[0028] The utility model discloses a highly integrated connector for multi-terminal signal transmission. Refer Figures 1-6 as shown, it includes: contact terminal 1, main body housing 2, glue 3, and end cap 4.

[0029] Refer Figures 1-2 as shown, the contact terminal 1 is a good conductor made of metal, is a rectangular strip, and has a plurality of clamping points 101 arranged around it for achieving interference fit with the main body housing 2, and a chamfer 102 is formed at one end of each contact terminal 1.

[0030] The main body housing 2 has four mating interfaces of different sizes, and each mating interface integrates different numbers of terminal holes 203.

[0031] Specifically, the main body housing 2 is partitioned into four mating interfaces of different sizes by retaining walls 201, and anti-fooling mating is achieved through the mating interfaces of different width dimensions. The card slot 202 is arranged on the periphery of the retaining wall 201 for achieving mating locking and fixation.

[0032] Refer Figures 1-4 as shown, preferably, a chamfer 204 is formed around each terminal hole 203, and each chamfer 204 cooperates with the chamfer 102 of the contact terminal 1 to guide the contact terminal 1 to be assembled through the terminal hole 203, achieving tight fit between the terminal hole 203 and the contact terminal 1. More specifically, in this embodiment, the main body housing 2 is partitioned into four different mating interfaces, and each mating interface has 4 groups of 66 uniformly distributed terminal holes 203.

[0033] Specifically, the position and height of the clamping points 101 are designed through experience. After assembling the main body housing 2, it can be verified through actual high-temperature testing (72H / 100 °C) that the main body housing 2 will not have stress cracking around the holes 203, improving position stability and reliability. The uniformly distributed terminal holes 203 can make the incoming contact terminals 1 be made into a tape mode, thereby realizing automatic feeding in production and improving production efficiency.

[0034] Refer Figures 1-5 as shown, an end cap 4 is provided at the tail away from the main body housing 2 of the connector. The end cap 4 is used for secondary positioning protection after the contact terminal 1 is assembled to prevent the contact terminal 1 from being skewed.

[0035] As shown in Figures 1-6 Figure 0, the glue 3 is provided on the bottom plane 205 at the tail of the main body housing 2. At the same time, a quantitative glue height is defined according to empirical values to achieve waterproof sealing without causing excessive waste of glue.

[0036] Specifically, the glue 3 is used to fill the assembly gaps around the contact terminal 1 and between the main body housing 1 and the terminal hole 203.

[0037] As shown in Figures 1-5 Figure 1, specifically, the end cap 4 is provided with a plurality of terminal through holes 401. A chamfer edging 402 is provided at the terminal through holes 401 on the side of the end cap 4 close to the main body housing 2. The chamfer 402 cooperates with the chamfer feature 102 of the contact terminal 1 to facilitate the smooth guiding of the contact terminal 1 through.

[0038] An arc angle 403 is further added to the edge of the chamfer 402 to reduce the stress fracture of the mold insert caused by the sharp edge and effectively improve the mold life. At the same time, the terminal through hole 401 and the contact terminal 1 are in clearance fit to avoid the assembly stress of the contact terminal 1 caused by repeated positioning due to the end cap 4.

[0039] As shown in Figures 1-5 Figure 2, the end cap 4 is further provided with two positioning posts 404. The bottom plane feature 405 of the positioning posts 404 can make the end cap stand stably on the bottom plane 205 of the main body housing 2, preventing the end cap 2 from shaking and affecting the assembly position accuracy of the contact terminal 1. The aforementioned glue 3 can also secondarily fix the positioning posts 404 of the end cap 4 to prevent the end cap 4 from shaking, so as to achieve the functions of further fixing the terminal and waterproof sealing, thereby obtaining reliable position accuracy and quality.

[0040] It can be seen from the above technical solutions that the present utility model has the following beneficial effects:

[0041] Through the space setting inside the main body housing, on the one hand, the present utility model can simplify the installation space of the connector and facilitate the positioning of the connector. On the other hand, it helps to meet the requirements of connection reliability and sealing. It has the advantages of simple structure, convenient installation, high process stability, and stable and reliable product structure. At the same time, the innovative multi - interface integration solution proposed in the scheme effectively solves the key technical bottlenecks such as signal integrity and mechanical reliability, so as to meet the usage in multiple scenarios and the diversified market demands.
