Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a connector assembly. Background Art

[0002] PCB board connector is a type of electronic connector, including terminal parts and connecting pins, etc., used for connecting PCB boards and boards, connectors, electronic connectors, communication equipment connectors, used for connecting communication equipment backplanes and daughter boards, industrial control backplanes and daughter boards, and precise and reliable connections.

[0003] According to Chinese patent CN213401579U, a connector plug-in structure for a PCB board is disclosed. The connector includes a female socket fixed on a first PCB board and a male socket fixed on a second PCB board. The female socket and the male socket are plug-connected. A number of middle needles are fixed in the female socket. The middle needles include an upper needle plate and a lower needle plate inserted into the female socket, and a middle needle contact pin exposed outside the female socket. An open clamping groove is formed between the upper needle plate and the lower needle plate for clamping the male socket contact piece. However, the upper needle plate and the lower needle plate have relatively regular shapes due to their own elastic force requirements. When they are molded and connected with the female socket, the upper needle plate and the lower needle plate are pressed into the female socket, which will generate stress interference on the female socket and cause deformation of the female socket.

[0004] Therefore, it is necessary to develop a connector assembly to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a connector assembly which reduces stress interference.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a connector assembly comprising:

[0007] A male socket, comprising a first upper contact terminal and a first lower contact terminal, and an inner plastic part covering the first upper contact terminal and the first lower contact terminal, wherein the first upper contact terminal and the first lower contact terminal are exposed from the inner plastic part;

[0008] The female socket includes a second contact terminal and a female socket plastic part that wraps the second contact terminal. The female socket plastic part has a docking groove formed by being recessed inward from its end surface, and a card slot that passes through the upper and lower surfaces of the female socket plastic part and is connected to the docking groove. The first upper contact terminal and the first lower contact terminal can be extended into the docking groove and abut against the second contact terminal. The second contact terminal is received in the card slot, and its side forms unequal barbs.

[0009] Furthermore, the card slot is located outside the docking slot and corresponds to the first upper contact terminal and the first lower contact terminal one by one.

[0010] Furthermore, the female seat includes an integrally formed female seat body, a female seat contact portion and a female seat docking portion. The female seat body is completely placed in the card slot, and unequal barbs and grooves are provided on both sides thereof.

[0011] Furthermore, the female socket contact portion is connected to one end of the female socket main body, and one end thereof extends obliquely toward the docking groove.

[0012] Furthermore, the female base docking portion is connected to the other end of the female base main body, and one end thereof is relatively raised.

[0013] Furthermore, the second contact terminals are divided into two rows and are relatively symmetrically arranged, and are respectively installed in the card slots. The second contact terminals in the upper and lower rows are spaced apart by a distance, which is greater than the distance between the first upper contact terminal and the first lower contact terminal.

[0014] Furthermore, the female seat also includes bushings, which are installed at both ends of the female seat plastic part and penetrate the upper and lower surfaces of the female seat plastic part for strong application installation and precise metal positioning.

[0015] Furthermore, the material is metal.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the present invention is a connector assembly with the characteristic of reducing stress interference. The second contact terminal is installed and positioned using a unilateral asymmetric barb design to avoid the stress interference of the barb pressed into the plastic, thereby solving the functional failure caused by plastic deformation caused by plastic extrusion.

[0030] Please see Figures 2 to 3 , the number of inner plastic parts 13 is a pair, which respectively wrap the first upper contact terminal 11 and the first lower contact terminal 12. Specifically, the structure of the pair of inner plastic parts 13 is the same, which respectively wrap the male seat body 111 of the first upper contact terminal 11 and the first lower contact terminal 12. In this embodiment, the pair of inner plastic parts 13 are rectangular, and both have a groove 131 formed inwardly from the surface thereof. The length and shape of the groove 131 can be changed according to needs. Preferably, a fixing protrusion 132 is provided on the surface of the first upper contact terminal 11 or the first lower contact terminal 12, and a fixing groove 133 is provided on the surface of the other first upper contact terminal 11 or the first lower contact terminal 12 opposite thereto. The fixing groove 133 extends into the fixing protrusion 132 to expand the contact area of the pair of inner plastic parts 13.

[0031] Please see Figure 4 The male socket 1 includes an outer plastic part 14, which wraps the first upper contact terminal 11, the first lower contact terminal 12 and the inner plastic part 13. The outer plastic part 14 has a receiving cavity 141 formed by being recessed inward from its outer end.

The shape of the docking groove 221 is consistent with the shape of the outer plastic part 14, and the outer plastic part 14 can extend into the docking groove 221. The card slot 222 is located on the outside of the docking groove 221 and is connected to the docking groove 221. The number of the card slots 222 is the same as the number of the first upper contact terminals 11 and the first lower contact terminals 12 and corresponds one by one.

[0034] The second contact terminals 21 are divided into two rows, upper and lower, and are relatively symmetrically arranged, and are respectively installed in the card slots 222.
