[0002] At present, electrical connectors are divided into circular electrical connectors and rectangular electrical connectors according to their shapes. The installation of tight components makes the shape of this type of connector flat and narrow, which makes it unsuitable for installation in some installation environments, and the processing of the rectangular shell is difficult, time-consuming, and expensive.
[0003] Circular electrical connectors have the characteristics of high contact density and small volume. series of miniature twist needle quick lock circular electrical connectors) generally use push-pull locking, relying on the friction of the ball and the spring for locking, which greatly reduces the overall size of the product, and has the characteristics of quick connection and quick separation, although the push-pull type Although the structure has the characteristics of fast locking and separation, the number of parts in the structure is too large, which is prone to failure, difficult to assemble, and poor interchangeability, and it is easy to cause balls to fall and get stuck. In actual use, the lock The phenomenon of not being able to enter or remove happens from time to time, which is very inconvenient to use

[0054] 5. Insulation resistance: ≥500MΩ;
[0055] 6. Dielectric withstand voltage: 600V.
[0056] Such as Figure 1 to Figure 11 As shown, the micro-circular four-pin electrical connector includes a plug assembly and a socket assembly. The plug assembly includes a plug housing 11, and the two ends of the plug ...
Embodiment 2
[0079] Such as Figures 12 to 15 Shown, a kind of assembly method of microcircular four-core electric connector, comprises the following steps:
[0080] A. Crimp the first cable 14 at the tail of the jack 13, and crimp the second cable 24 at the tail of the pin 23; specifically, crimp the wires of the corresponding cable to the tail of the jack 13 or the pin 23;
[0081] B. Adhesively fix the socket 13 connected with the first cable 14 on the socket base 12, insert the pin 23 connected with the second cable 24 on the pin base 22, and then insert the pin 23 Bonding and fixing on the pin base 22, the adhesive can be DG-4 adhesive when bonding, and the glue must not exceed the tail boundary of the jack base 12 and the pin base 22;
[0082] C. Install the jack base 12 connected with the jack 13 in the plug housing 11, and form the cavity between the outer circumference of the end where the first cable 14 is connected to the jack 13 and the inner wall of the jack 13 housing Inject ...

Abstract
The invention discloses a mini round four-core electric connector. The mini round four-core electric connector comprises a plug component and a socket component. The plug component comprises a plug shell. A jack base, a jack and a first cable are mounted in the plug shell. A connection ring and a plug bushing sleeve the plug shell. A clamp ring is arranged at the joint between the connection ringand the plug shell. The socket component comprises a socket shell. A pin base is mounted in the socket shell. A pin is fixed to the pin base. A second cable is connected with the pin. An O-ring is arranged on a waist pad of the socket shell. Locking nuts are mounted on two sides of the socket shell. The mini round four-core electric connector shares the features of high contact density and small size with round connectors, has the advantages of high density, lightweight and microminiaturization, can be applied to severe environments with high vibration and impact, is applicable to occasions with special requirements on space and equipment lightweight, and can be widely applied to aviation and spaceflight fields and environments with large environment temperature change.
