Features of cable connectors and assembly quality control measures
The purpose of the cable connector
Cable connectors are mainly used to transmit data, audio, video and other communication equipment. Various types of digital program-controlled switches, photoelectric transmission equipment internal connection and signal transmission between distribution frames, used to transmit data, audio, video and other communication equipment. The sheath is made of flame-retardant materials with high safety factor. It adopts advanced technology to make the cable have good flame-retardant and anti-uniformity. Multi-core cables make the rack installation more convenient.
Preparation before processing the cable connector
Check the required tools: (Scale, Allen wrench, tap, board file, hand saw, blade or electrician's knife, special metal scissors, hammer, emery cloth, needle-nose pliers, nozzle pliers, wire pliers, screwdriver, copper brush, special installation tools).

Assembly quality control measures for cable connectors
In the assembly of electronic products, cable connectors are widely used. It is a key product to ensure the correctness and reliability of electrical signal transmission. There are many types of cable connectors, mainly divided into low frequency, high frequency, round and rectangular. In the assembly process of the cable connector, in order to ensure product quality, a number of effective quality control measures should be taken in each link. The selection, pretreatment, crimping or welding, and testing of cable connectors should be strictly controlled. If there is a problem with the quality of the assembly, such as: The ground wire is broken; Cable core wire and core wire; The core wire is short-circuited with the shell of the electrical connector; Failure phenomena such as poor contact of electrical connector contact pairs will inevitably seriously affect the reliability of the entire electronic product and system. Therefore, in the assembly production process, effective quality control measures should be taken for the assembly process of the cable connector.
Quality control measures of XKE type cable connector
XKE series small circular electrical connectors have the characteristics of high contact density, good sealing performance, high reliability, and good three-proof performance. It has been widely used in aviation, aerospace, weapons, electronics and other industrial products. It is composed of a sealed body, a shell, a connecting nut, a socket (needle), an insulator and a positioning claw. It adopts bayonet connection, which is fast and self-locking. The single pinhole of this connector can be taken and sent, and the pinhole and wire are connected by crimping. Through the actual application of production, the main points of control measures for assembling XKE connectors are summarized.
(1) Selection of crimping wires, pins (holes), and crimping tools (equipment). The cross-sectional area of the wire is selected according to the size of the current through the wire.
(2) For XKE type connectors with shielding structure, the shielding sleeve of the cable should be welded on the flange circumference between the shielding outer sleeve and the shielding inner sleeve. It is strictly forbidden to compress the shielding sleeve only with the accessories of the connector. It may cause the shielding sleeve to be loose and fall off during use, resulting in an unreliable phenomenon of poor resistance contact.
(3) In order to avoid the hidden danger of short circuit caused by the short-circuit wire and the accessories of the connector, the short-circuit wire in the connector should be tied or split with a joint.
(4) Special supporting tools should be used for loading and unloading connector tail accessories. It should be ensured that the connector is connected reliably during installation, and it should be ensured not to damage the appearance of the connector during disassembly.
