Frequently asked questions about Micro Crimp Socket Connector

Are crimp style connectors good?

Good micro crimp style connectors can be used on solid or stranded conductors, and provides a good mechanical and electrical connection.

Is it better to solder or crimp?

Crimping offers stronger, more reliable connections than soldering. Soldering uses heated metal to join the cable to the connector. Over time, this filler metal will degrade, which may cause the connection to fail. Most electricians will agree thatcrimping is also easier than soldering.

What is micro crimp style connectors used for?

Crimp connections are used typically to fix connectors, such as BNC connectors, to coaxial cables quickly, as an alternative to soldered connections. Typically the maleconnector is crimp-fitted to a cable, and the female attached, often using soldered connections, to a panel on equipment.

The standards of our military power connectors include 83513 Micro-D and COTS connectors provide a reliable solution for all high-performance interconnect requirements including high temperature and hermetic applications.

MIL-DTL-32139 Nano D Connectors

The MIL-DTL-83513 and MIL-DTL-32139 specifications define the minimum acceptable performance levels for Micro-D and Nano miniature connectors. While the specs are rigid in their performance benchmarks, manufacturers are given considerable leeway when it comes to contact design, crimp fabrication, contact finish and material selection. Stamped and formed contacts, for example, are widely used in Micro-d connectors due to their low cost and ease of manufacture. But independent testing clearly shows that Twist Pin style contacts provide superior performance in such areas as high-temperature tolerance, contact retention and crimp strength. If you have already made the decision to use either a Micro-D or Nano military specification connector because its ruggedized performance outweighs the potential cost-savings realized in a lesser-caliber connector, then you owe it to yourself to understand the very real differences between stamped pins and the Sunkye Twist Pin Contact System.

Sunkye Hermetic Sealed Connectors enable efficient electrical signal and power transmission in severe situations like high temperature high pressure and highly corrosive chemicals.

Glass-to-metal sealing is a technique to hermetically insulate electrical conductors that pass from one side of a barrier to the other. The glass melts to both the package and pin, it can act as an airtight barrier and, in the meantime provide insulation between the housing and the pins. In the oil and gas field, as hermetically sealed feedthroughs used to conduct power or signals through the metal walls of vessels of liquefied gas tanks, they must operate reliably for the long term.

Glass-to-metal seals can be manufactured for high-temperature high-pressure connectors onshore and offshore, this type of seals are suitable for high-pressure applications (up to 60,000psi). High-temperature operation from -55 degrees to 350 degrees.

Glass to metal seal applications in Oil and gas fields are sub-sea cable termination & condition monitoring, containment seal/fire barrier and wireline tools (measurement/logging whilst drilling), etc. So, it is true that the feedthroughs require hermetic or airtight seals that can withstand severe conditions such as high temperature, high pressure, vibration, moisture, and difficult chemical environments.

Sunkye High-temperature high-pressure glass to metal sealed military connectors are protected against extreme conditions and are engineered for very high reliability. The glass is a good electrical insulator and it has low thermal conductivity, along with the capacity to withstand high operational pressure and temperature. The housing material is Kovar, this type of matched seal have the advantage that only small levels of residual stress are present and the feedthrough can withstand very high temperatures.

Ⅰ. What is an electrical connector?

An electrical connector is a device that connects two active devices to transmit current or signals. A connector is a detachable element (except for adapters) that is usually installed on the cable supplier or equipment for the electrical connection of the transmission line system, that is, a device that connects two active devices to transmit current or signals.

Ⅱ. The function of the electrical connector

The role of the electrical connector is very simple: it builds a bridge of communication between the blocked or isolated circuits in the circuit, so that the current can flow and the circuit can realize the predetermined function.

Electrical connectors are an indispensable part of electronic equipment. Observing along the path of current flow, you will always find one or more electrical connectors. The form and structure of electrical connectors are ever-changing. There are various types of connectors with different application objects, frequencies, power, and application environments, such as multi-wire electrical connectors.

Generally speaking, what the electrical connector is connected to is not limited to current. In today’s rapid development of optoelectronics technology, the carrier of transmitting signals is light in the optical fiber system. Glass and plastic replace the wires in ordinary circuits, but light Connectors are also used in signal paths, and their functions are the same as electrical connectors.

Ⅲ. The characteristics and advantages of electrical connectors

1. Improve the production process

The connector simplifies the assembly process of electronic products. It also simplifies the mass production process;

2. Easy to repair

If an electronic component fails, the failed component can be quickly replaced when an electrical connector is installed;

3. Easy to upgrade

With the advancement of technology, components can be updated when electrical connectors are installed, and new and more complete components can be used to replace the old ones;

4. Improve design flexibility

The use of electrical connectors allows engineers to have greater flexibility when designing and integrating new products and when composing systems with components.

The connection forms of industrial electrical connectors can be roughly divided into four types, and more types are currently used. Here are four industrial electrical plug types:

Threaded connection

Some types of connections are commonly used for contacts with larger dimensions and the military electrical connector that operate in high vibration environments. This type of connection can be equipped with a fuse to prevent loosening after the connection is completed. The connection is reliable, but the connection is slow.

Bayonet connection

This is a reliable and fast form of connection and disconnection. Most electrical connectors in the form of a card 121 connection have a visual display of proper connection and locking, and can be seen through a small hole on the side of the electrical connector’s connection nut.

In-line connector

This is a versatile form of connection. When the plug and military socket of the electrical connector are connected and disconnected, the moving direction is usually a reciprocating linear motion, without twisting and rotating, and only requires a small working space to complete the loading and unloading. Common plug-in connections come in spherical or pin configurations. Because there is no mechanical labor-saving mechanism in the connection form, once it is inserted incorrectly, the mechanical resistance increases significantly and can be found in time.

Military electrical connector cabinet connection

As one type of the industrial connectors electrical, it was used on some devices and requires a blind connection near the frame. It can make electrical equipment lighter, smaller, easier to maintain and more reliable.

This type of connection prevents the operator from feeling the connection. It is necessary to design an accurate positioning device to avoid forcibly connecting the wrongly inserted micro electrical connectors together, so that the wrong insertion cannot be performed. Cabinet-type electrical connectors are usually designed with floating or resilient contacts to ensure proper connection.

Circular connectors play an important role in electronic engineering construction, ensuring the smooth flow of circuits, so they are widely used. At present, there are many types of circular electrical connectors on the market, with various specifications and styles, and there are also many excellent connection technologies. At present, there are four connection methods that are commonly used. Let’s introduce the specific content below!

1. Thread connection method of circular connector

A connection form that is often used by circular connectors that have larger-sized contacts and work in a strong vibration environment. This type of connection can be installed with a fuse to prevent loosening after the connection is completed. This connection form is reliable to use, but the connection and disassembly speed is slow.

2. The bayonet connection method of the circular connector

It is a reliable and rapid connection and separation form. Most card 121 connection style micro circular connectors have a visual indication of proper connection and locking, which can be viewed from the small hole on the side of the circular connector connection nut.

3. The plug-in connection method of the circular connector

is a versatile form of connection. When the plug and socket of the military circular connector are connected and separated, the moving direction is usually a reciprocating linear motion, without twisting and rotating, and only a small working space is required to complete the connection and disassembly.

Common plug-in connections have two structures: balls or pins. Because there is no mechanically labor-saving mechanism in this connection form, once it is mis-inserted, the mechanical resistance will increase significantly, and it can be found in time.

4. Cabinet connection method of circular connector

It is suitable for circular connectors on some equipment that is close to the frame and needs to be connected blindly, which can make electrical equipment lighter and smaller, easier to maintain and more reliable.

This type of connection makes the operator unable to feel the connection, and an accurate positioning device must be designed to avoid forcing the misinserted circular connectors together, making misinsertion impossible. Cabinet circular connectors usually adopt floating or elastic contact design structure to ensure their correct connection.
