Detailed Implementation

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] This application provides a 360° contact connector, which solves the problems of poor contact and high cost in the prior art.

[0023] like Figures 1 to 2 As shown in the embodiment of this application: a 360° contact connector, including: a male connector 1 and a female connector 2. The male connector 1 includes a male PCB board 11, a male plastic 10, and a male terminal 12. The male plastic 10 has multiple fixing holes 100 inside. One end of the male plastic 10 has a thread on its outer periphery, and the end away from the thread has the male PCB board 11. The male terminal 12 passes through the fixing holes 100 and the male PCB board 11. The female connector 2 includes a female PCB board 21, a female plastic 20, and a female terminal 23. The female plastic 20 has multiple channels 200. One end of the female plastic 20 has a nut 22 on its outer periphery, and the end away from the nut 22 has the female PCB board. The female terminal 23 passes through the channels 200 and the female PCB board 21. When the male terminal 12 is inserted into the female terminal 23, the female plastic 20 and the male plastic 10 are connected by mating with the nut 22 and the thread.

[0024] Reference Figures 3-5 The male terminal 12 has a ring of outwardly protruding contact bumps 121 at its front end. The female terminal 23 has a cylindrical structure. The male terminal 12 extends into the female terminal 23, and the contact bumps 121 contact the female terminal 23.

[0025] By stamping the sheet metal into cylindrical female terminal 23 and male terminal 12, contact bumps 121 are further made on the male terminal 12. The contact bumps 121 are more stable than the general spring contact, which can achieve a stable connection and 360° terminal contact. This avoids the limitation of the spring arm type terminal, and the cross-section of the terminal is fully utilized, so that it can carry a larger current.

[0026] Reference Figure 5 The male connector plastic 10 has at least one pair of snap-fit ​​protrusions 102 on the inner wall of the fixing hole 100, and the male connector terminal 12 has at least one pair of outwardly protruding anti-retraction pieces 122. The at least one pair of anti-retraction pieces 122 abut against the snap-fit ​​protrusions 102 to prevent the male connector terminal 12 from moving forward.

[0027] Further reference Figure 2 The fixing hole 100 inside the male connector plastic 10 is also provided with a stop groove 101, and the rear end of the anti-reverse piece 122 is provided with a stop piece 120. The stop piece 120 abuts against the stop groove 101, which can further prevent the male connector terminal from moving backward.

[0028] like Figures 6-8 As shown, the female plastic base 20 is provided with a retaining boss 202, and the rear end of the nut 22 is provided with an inwardly extending flange 220, which abuts against the retaining boss 202. The function of the retaining boss 202 is to prevent the assembled nut 22 from coming off. The female plastic base 20 is provided with a ring of outwardly protruding hanging platform 201 in the middle, which is connected to the inner wall of the nut 22. The hanging platform 201 also prevents the nut 22 from falling off from the other end.

[0029] The 360° contact connector in this embodiment can be used with both a PCB board and a cable. Specifically, it also includes a male connector cable 13 and a female connector cable 24. The male connector PCB board 11 has a first through hole 110 and the female connector PCB board has a second through hole 210. The male connector cable 13 passes through the first through hole 110 and is connected to the male connector terminal 12, and the female connector cable 24 passes through the second through hole 210 and is connected to the female connector terminal 23.

[0030] The assembly method of the 360° contact connector in this embodiment is as follows:

[0031] The female terminal 23 and the female plastic 20 are assembled into a semi-finished product by insert molding. The nut 22 is assembled onto the semi-finished product by a fixture. During the assembly process, the nut 22 is interference-fitted through the anti-reverse boss 202 on the female plastic 20. After the female terminal 23, the female plastic 20 and the nut 22 are assembled, the female connector 2 is formed.

[0032] The male connector terminal 12 is assembled onto the male connector plastic 10 using a fixture. After the male connector terminal 12 is inserted into the correct position in the male connector plastic 10, the anti-retraction piece 122 on the male connector terminal 12 pops up and engages with the snap-fit ​​protrusion 102 inside the male connector plastic 10, preventing the male connector terminal 12 from being removed from the male connector plastic 10. At the same time, the stop piece 120 on the male connector terminal 12 also reaches the correct position and engages with the stop groove 101 on the male connector plastic 10 to prevent the male connector terminal 12 from being inserted too deeply.

[0033] After assembly, the male connector 1 and female connector 2 are connected by mating. The male terminal 12 is inserted into the female terminal 23, and the threads and nuts 22 are used to connect the male and female connectors.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the scope of protection of this utility model.
