[0002] In general, there will be a scenario of off-line sub-module testing for PCBA modules. When removing the module with quick insertion terminals, frequent disassembly and assembly have a high probability of causing fatigue deformation of the male terminal, resulting in poor contact or damage of the terminal. The occurrence of this situation will lead to inconsistent variables in the hardware connection during the testing process, resulting in inaccurate test results and increased time and labor costs. Content of the Utility Model

Through the mutual cooperation of the misaligned cards and the misaligned card slot, the degree of freedom of the first base card in the vertical direction of the space perpendicular to the horizontal plane is restricted. The limiting pins are slidably connected with the limiting slot. Through the mutual cooperation of the limiting pins and the limiting slot, the degree of freedom of the first base card in the horizontal plane perpendicular to its target movement direction is restricted, so as to ensure that the plug and the connector have only one degree of freedom of movement during insertion, and the PCBA boards are connected together by a split splicing method.

[0025] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.

[0026] Embodiment: In view of the characteristic that the movement direction of the quick insert generally has only one degree of freedom (horizontal / vertical movement in the quick insert direction); the present utility model provides a quick-insert connection auxiliary device for patch terminals, as Figure 1 and 2As shown, it includes a plug 1, a connector 2 and a connection auxiliary component. The connection auxiliary component includes a first base card 301, a second base card 302, a first PCBA board 303 and a second PCBA board 304. The plug 1 is installed on one side wall surface of the first PCBA board 303, and the connector 2 is installed on one side wall surface of the second PCBA board 304. The wires on the plug 1 and the connector 2 are respectively connected to the first PCBA board and the second PCBA board 304 by welding. And the plug 1 and the connector 2 are respectively close to the edges of the first PCBA board 303 and the second PCBA board 304. The other side wall surface of the first PCBA board 303 is connected to the other side wall surface of the first base card 301. A nut post 4 is provided between the first PCBA board 303 and the first base card 301. The nut post 4 is installed around the card slot 305. The other side wall surface of the second PCBA board 304 is connected to the other side wall surface of the second base card 302. A panel fastener 5 is provided between the second PCBA board 304 and the second base card 302.

[0027] Among them, as Figures 2 - 6As shown, a card slot 305 is provided on the first base card board 301. The card slot 305 is located at the middle position of the first base card board 301. The second base card board 302 is located at the front end of the second PCBA board 304 and is respectively provided with a misaligned card slot 306 and a limiting slot 307. The misaligned card slot 306 is perpendicular to the long side direction of the second base card board 302, and the misaligned card slot 306 is formed by stamping with a forming tool; the limiting slot 307 is parallel to the long side direction of the second base card board 302. One end wall surface inside the card slot 305 is symmetrically provided with misaligned card plates 308. On the back surface of the first base card board 301 on one side of the card slot 305, limiting pins 309 are symmetrically provided. The model of the limiting pin 309 is MPP-1MM-3; the misaligned card plates 308 are engaged with the misaligned card slot 306. Through the mutual cooperation of the misaligned card plates 308 and the misaligned card slot 306, the degree of freedom of the first base card board 301 in the vertical direction of the space with the horizontal plane is restricted. On one side of the first base card board 301 facing the second PCBA board 304, semi-circular grooves 311 are symmetrically provided. The semi-circular grooves 311 are engaged with the panel fasteners 5 to assist the plug 1 and the joint 2 in being inserted into each other. Auxiliary push plates 310 are provided on both sides of the first base card board 301. The auxiliary push plates 310 wrap the second base card board 302 on both sides to assist the first base card board 301 to first vertically cover the surface of the second base, and then push the first base card board 301 to move inward and cooperate with the second base card board 302; the limiting pin 309 is slidably connected with the limiting slot 307. Through the mutual cooperation of the limiting pin 309 and the limiting slot 307, the degree of freedom of the first base card board 301 in the horizontal plane perpendicular to its target movement direction is restricted. Finally, the movement perpendicular to the movement direction in the horizontal plane is restricted by the limiting pin 309 with a precise size, and the misaligned card plates 308 are used to restrict the vertical movement in the Z-axis space, so as to ensure that there is only one degree of freedom of movement when the plug 1 and the joint 2 are inserted. The two groups of PCBA boards are connected together by adopting a split splicing method.

[0028] Specific working principle:

[0029] First, align the slot 305 on the first base card 301 with the area on the second base card 302 that does not contain the second PCBA board 304. Then, control the auxiliary push plate 310 to move the limit pin 309 on the first base card 301 along the limit groove 307 on the second base card 302 inward by a certain distance until the misaligned card 308 is pushed into the misaligned slot 306. At this time, the plug 1 will be inserted into the connector 2, and then the PCBA module with quick-connect terminals will complete a movement with only one degree of freedom, restricting the degrees of freedom that cause fatigue deformation to other pairs of terminals, thus ensuring removal, greatly reducing the insertion loss rate of the terminals, ensuring the performance of the terminal contact, and reducing the waste of labor costs.

[0030] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
