[0028] The following will be combined with the drawings in this embodiment of the utility model to clearly and completely describe the technical solution in this embodiment of the utility model. Obviously, the described embodiment is one embodiment of the utility model, not all embodiments of the utility model. Based on this embodiment of the utility model, all other embodiments of the utility model obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please refer to Figures 1 to 8 , the utility model provides a communication connector.

[0030] like Figure 1 As shown, the communication connector includes an outer shell 1, which is made of PC plastic material. The outer shell 1 is an insulator and can be directly touched by human hands. At the same time, the outer shell 1 can be manufactured separately before assembly.

[0031] like Figure 2 As shown, five conductive pins 2 and cables 3 electrically connected to the conductive pins 2 are installed inside the outer shell 1; the conductive pins 2 have high rigidity and are generally made of copper, and the cables 3 are general metal wires that can be bent freely.

[0032] A cable plug 4 is also installed inside the outer shell 1. One end of the cable plug 4 is provided with a positioning block 41 for positioning the conductive pin 2, and the other end is provided with a positioning groove 42 for positioning the cable 3; further, during the assembly process, the conductive pin 2 and the cable 3 are electrically connected together to form a whole, which can be specifically connected together by soldering or fixed together by riveting.

[0033] During assembly and placement, the conductive pin 2 is placed inside the positioning block 41, and the cable 3 is placed inside the positioning groove 42. In this way, the conductive pin 2, the cable 3 and the cable plug 4 are connected together. Furthermore, the conductive pin 2, the cable 3 and the cable plug 4 are placed inside the outer shell 1 and assembled with the outer shell 1. Molten plastic is injected into the outer shell 1 to fill the gap between the conductive pin 2, the cable 3, the cable plug 4 and the outer shell 1. After cooling, a glue injection block 5 is formed. The above-mentioned method of injecting molten plastic is to adopt in-film molding. The glue injection block 5 fixes the conductive pin 2, the cable 3, the cable plug 4 and the outer shell 1 together to form a complete communication connector. At this time, Figure 1 As shown, the end of the conductive pin 2 extends out of the outer shell 1, and the end of the cable 3 extends out of the glue injection block 5.

[0034] The injection block 5 is formed by insert-molding, and is coated on the conductive pins 2, cables 3, cable plugs 4 and the outer shell 1, fixing the aforementioned components into a whole, which is convenient for the following process. The injection block 5 can be plastic, but the present invention does not limit the material and molding process of the injection block 5, as long as the injection block 5 can be formed to cover the aforementioned multiple components to form a whole.

[0035] like Figure 2 As shown, the conductive pins 2 are divided into two parts, wherein four conductive pins 2 are at the top, belonging to the first part; another conductive pin 2 is at the bottom, belonging to the second part; correspondingly, in order to place the conductive pins 2, as shown in FIG. Figure 7 and Figure 8 As shown, the positioning block 41 also consists of two parts, including four first U-shaped grooves 411 on the front of the cable plug 4 and a second U-shaped groove 412 installed on the back of the cable plug 4. The first U-shaped groove 411 and the second U-shaped groove 412 are arranged horizontally and symmetrically, corresponding to the conductive pin 2; the bottom of the first U-shaped groove 411 and the second U-shaped groove 412 are arc-shaped to accommodate the cylindrical conductive pin 2.

[0036] Further, such as Figure 7 and Figure 8 As shown, the first U-shaped groove 411 and the second U-shaped groove 412 isolate and separate the five conductive pins 2 so that they will not interfere with each other, thereby facilitating subsequent glue injection; further, the shape and size of the first U-shaped groove 411 and the second U-shaped groove 412 correspond to and adapt to the conductive pins 2; they can be adaptively changed and adjusted according to the number and thickness of the conductive pins 2, guide the conductive pins 2 to separate from each other, and can also temporarily fix the conductive pins 2.

[0037] like Figure 7 and Figure 8 As shown, the sides of the first U-shaped groove 411 and the second U-shaped groove 412 are both provided with first arc-shaped protrusions 413, and the first arc-shaped protrusions 413 are close to each other to restrict the conductive pin 2 and fix the conductive pin 2, so that the conductive pin 2 can be stably assembled.

[0038] like Figure 6 As shown, the same as the conductive pins 2, the number of the cables 3 is also five; the difference from the conductive pins 2 is that the five cables 3 are in a row and arranged horizontally, and correspondingly, the positioning grooves 42 also need to be changed accordingly.

[0039] Specifically, Figure 7 and Figure 8 As shown, the positioning groove 42 includes five third U-shaped grooves 421 installed on the front side of the cable plug 4 and a fourth U-shaped groove 422 installed on the back side of the cable plug 4. The third U-shaped groove 421 and the fourth U-shaped groove 422 are arranged in a row horizontally, the third U-shaped groove 421 is on the right side, and the fourth U-shaped groove 422 is on the left side. The third U-shaped groove 421 and the fourth U-shaped groove 422 are provided with a hollow portion 424 at one end and a separation protrusion 423 at the other end. The hollow portion 424 is provided to facilitate the injection block 5 to fix the cable 3 and the cable plug 4. In addition, the hollow portion 424 can also facilitate observation of whether each cable 3 is installed and whether it has fallen off, which is conducive to inspection and improving the qualified rate of finished products; the separation protrusion 423 is provided to isolate the cables 3 from each other.

[0040] Further, such as Figure 7 and Figure 8 As shown, the third U-shaped groove 421 and the fourth U-shaped groove 422 isolate and separate the five cables 3 so that they will not interfere with each other, thereby facilitating subsequent glue injection; further, the shapes and sizes of the third U-shaped groove 421 and the fourth U-shaped groove 422 correspond to and adapt to the cables 3; specifically, the bottoms of the third U-shaped groove 421 and the fourth U-shaped groove 422 are arc-shaped to accommodate the cylindrical cables 3; adaptive changes and adjustments are made according to the number and thickness of the cables 3 to guide the cables 3 to separate from each other, and the cables 3 can also be temporarily fixed.

[0041] like Figure 7 and Figure 8 As shown, the side surfaces of the separation protrusions 423 are provided with second arc-shaped protrusions 425 , and the second arc-shaped protrusions 425 are close to each other to restrict and fix the cable 3 , so that the cable 3 is stably assembled.

[0042] like Figure 5 and Figure 6As shown, a positioning ring 21 is provided in the middle of the conductive pin 2, and the first U-shaped groove 411 and the second U-shaped groove 412 are located on one side of the positioning ring 21 to block the positioning ring 21 and position the conductive pin 2. When the conductive pin 2 is inserted into the through hole 11 on the outer shell 1, the first U-shaped groove 411 and the second U-shaped groove 412 block the positioning ring 21, so that the conductive pin 2 can smoothly pass through the through hole 11, and the exposed length of the conductive pin 2 is also consistent, which can be effectively controlled, thereby improving the consistency of the finished product.

[0043] like Figure 4 As shown, the outer shell 1 is provided with a plurality of holes 11 for passing the conductive pins 2 through, and a positioning ring groove 12 is provided around the hole 11. The positioning ring groove 12 is used to prevent the positioning ring 21 from extending, and cooperates with the first U-shaped groove 411 and the second U-shaped groove 412 to position the conductive pin 2; in this way, both the extension and retraction of the conductive pin 2 are restricted, so that the exposed length of the conductive pin 2 can remain stable during multiple plugging and unplugging processes, thereby making the connection stable and having a higher number of plugging and unplugging times and service life.

[0044] In order to make the conductive pin 2 better inserted into the through hole 11, the end of the through hole 11 is set to be hemispherical. At the same time, in order to facilitate the matching of the positioning ring 21 with the positioning ring groove 12, the end of the positioning ring groove 12 is also provided with a guiding slope 13 for guiding the insertion of the positioning ring 21. The positioning ring 21 is inserted into the interior of the positioning ring groove 12 through the guiding slope 13 to achieve a stable connection.

[0045] like Figure 2 As shown, the side of the outer shell 1 is provided with a plurality of arc grooves 14, which can increase the friction between the hand and the outer shell 1, and is convenient for plugging and unplugging the communication connector; in order to facilitate matching or connecting with another communication connector, the side of the outer shell 1 is also provided with a matching groove 15 that matches with another communication connector, and the inner side of the outer shell 1 is also provided with a positioning inclined surface 16 that facilitates the positioning of another communication connector. Correspondingly, the other communication connector should be provided with a matching protrusion corresponding to the matching groove 15 and a positioning protrusion corresponding to the positioning inclined surface 16.

[0046] like Figure 5As shown, the end of the conductive pin 2 is provided with an insertion hole 22 for accommodating the cable 3, and the insertion hole 22 is provided with an observation hole 23 for observing the cable 3 in the radial direction, and the observation hole 23 is connected with the insertion hole 22, so as to observe the cable 3 inserted into the insertion hole 22. The cable 3 is inserted into the insertion hole 22, and the cable 3 is observed from the observation hole 23, which means that the cable 3 is inserted into the insertion hole 22, and the insertion hole 22 is riveted, so that the insertion hole 22 is deformed, and the conductive pin 2 and the cable 3 are riveted together.

[0047] The steps of assembling the communication connector;

[0048] Step S1: Connect the conductive pin 2 and the cable 3 together; peel one end of the cable 3 to expose the copper wire, insert the copper wire into the insertion hole 22, observe through the observation hole 23, and observe the copper wire, indicating that the copper wire is inserted in place, and rivet the insertion hole 22 to deform the insertion hole 22, and rivet the conductive pin 2 and the cable 3 together;

[0049] Step S2: Place the conductive pin 2 and the cable 3 and connect them with the cable plug 4; place the conductive pin 2 inside the first U-shaped groove 411 and the second U-shaped groove 412, the positioning ring 21 is located on one side of the first U-shaped groove 411 and the second U-shaped groove 412, adjust the cable 3, place the cable 3 in the third U-shaped groove 421 and the fourth U-shaped groove 422, and the five cables 3 can be observed from the hollow part 424 to complete the placement;

[0050] Step S3: insert the conductive pin 2, the cable 3 and the cable plug 4 into the outer shell 1, and sequentially pass the conductive pin 2 through the guide slope 13, the positioning ring groove 12 and the through hole 11, and extend out from the outer shell 1, wherein the positioning ring 21 is fixed inside the positioning ring groove 12; the through hole 11 limits one side of the positioning ring 21, and the first U-shaped groove 411 and the second U-shaped groove 412 limit the other side of the positioning ring 21, thereby fixing and limiting the conductive pin 2;

[0051] Step S4: Place the conductive pin 2, cable 3, wiring plug 4 and outer shell 1 into an injection molding machine, and use the in-mold molding method to inject molten plastic into the inner part of the outer shell 1 to fill the gap between the conductive pin 2, cable 3, wiring plug 4 and outer shell 1. After cooling, a glue injection block 5 is formed, and the glue injection block 5 fixes the conductive pin 2, cable 3, wiring plug 4 and outer shell 1 together to form a complete communication connector, thereby completing the assembly of the communication connector.
