The terminal of the creative communication connector can be a crimp terminal, specifically a fisheye terminal in the crimp terminal, and the terminal of the communication connector is used to further improve the conventional fisheye hole. Terminals to improve crimp reliability. The implementation of this creation will be described in detail below, and it is believed that the purpose, features and characteristics of the creation can be deeply and specifically understood.

Please refer to FIG. 1 to FIG. 4, which is the terminal of the communication connector of the present invention. As shown in FIG. 1, the terminals (S10, S20, S30, S40, S50, S60) of the present communication connector each include a contact tail section (13, 23, 33, 43, 53, 63). For convenience of explanation, the terminal S10 of the communication connector will be described as an example below.

As shown in Figures 1, 2A and 2B, the terminal S10 of the communication connector basically comprises a contact head section 11, an extension 12 connected to the contact head section, and a contact extending outward from the extension section 12 by a length L. Tail segment 13. In detail, the contact head segment 11 is for mating with another terminal (not shown) to form an electrical contact, and the contact tail segment 13 is for crimping with the conductive via M1 of the circuit board M. Figure 5) to form an electrical contact. A through hole G is formed in the center of the contact tail portion 13, and the through hole G is preferably a fisheye through hole (or a pinhole through hole). As shown in FIGS. 3 and 4, the distance from one side to the other side of the extension 12 is defined as the thickness T1 of the extension 12, and the distance from one side of the contact tail 13 to the other side is defined as the thickness T2 of the contact tail 13 And the extension section 12 is formed in a height difference state with the contact tail section 13 in the thickness direction, and the thickness T2 of the contact tail section 13 is smaller than the thickness T1 of the extension section 12. That is, one side of the contact tail section 13 is coplanar with one side of the extension section. In another modified embodiment, as shown in FIG. 8, the two sides of the extending section 12 are respectively formed in a height difference state with the two sides of the contact tail section 13 in the thickness direction, and the thickness T2' of the contact tail section 13 is smaller than the extension. The thickness T1 of the segment 12. In other words, the two sides of the contact tail section 13 are parallel to both sides of the extension section 12, and the two sides of the contact tail section 13 are interposed between the two sides of the extension section 12.

Preferably, in an exemplary embodiment, the ratio between the thickness T1 of the extension 12 and the thickness T2 of the contact tail 13 is 4:3, and the ratio is 1.333. More specifically The thickness T1 of the extension 12 is about 0.4 mm, and the thickness T2 of the contact tail 13 is about 0.3 mm. Therefore, the thicknesses of the foregoing two differ by a ratio of about 1/4.

As shown in FIGS. 2A and 2B, the contact tail section 13 includes a base portion 131 along its length L direction, two elastic portions (132a, 132b) connected to the base portion 131, and two elastic portions (132a, 132b). A distal end portion 133. The base portion 131 is a portion having a strong structural rigidity to provide sufficient strength of the terminal S10 of the communication connector to prevent the terminal S10 of the communication connector from being bent when the conductive via M1 of the circuit board M is crimped. The two elastic portions (132a, 132b) generate interference when the terminal S10 of the communication connector is crimped to the conductive through hole M1 of the circuit board M to provide insertion force and holding force. The terminal portion 133 is used for guiding when the terminal S10 of the communication connector is crimped to the conductive via M1 of the circuit board M. The fisheye-shaped through hole G is located between the two elastic portions (132a, 132b). The thickness T2 of the contact tail section 13 is the thickness of the two elastic portions (132a, 132b) and is equal to the depth D of the fisheye-shaped through hole G (Fig. 4). Specifically, the two elastic portions (132a, 132b) are symmetrical to each other and are respectively curved, and the distance between the outer surfaces of the curved portions of the two elastic portions (132a, 132b) can be defined as the width of the contact tail portion 13. W. Generally, the length L of the contact tail section 13 is adjusted according to the depth of the conductive via M1 to be crimped to the circuit board M, and the width W of the contact tail section 13 is based on the conductive via which is to be crimped to the board M. Adjust the diameter of M1.

Referring to FIG. 5 to FIG. 7 , the terminal S10 of the present communication connector is electrically connected to the conductive via M1 of the circuit board M. The conductive via M1 can have any diameter and depth according to design requirements. In general, the length L of the contact tail segment 13 of the terminal S10 of the communication connector is greater than the depth of the conductive via M1, and the width W of the contact tail segment 13 is slightly larger than the diameter of the conductive via M1 to avoid the elastic portion during crimping ( 132a, 132b) The interference is too large, and the fish-eye-shaped through hole G has elastic contractibility to digest the force at the time of crimping, so that the terminal S10 of the communication connector is not twisted and deformed. However, the elastic portions (132a, 132b) must be designed to be symmetrical, and the fisheye-shaped through holes G must also maintain their symmetry so that the amount of contraction deformation during interference is uniform. But in practice, the fish-eye through hole G must be designed and processed. Strictly controlled, otherwise the symmetry cannot be achieved and the result is not good, but the contact tail section 13 of the terminal S10 of the present communication connector is thinner than the extension section 12, so that the two elastic parts (132a, 132b) The thickness of the through hole G is shallower than that of the conventional one, and the depth of the through hole G of the fisheye is shallower than that of the prior art, and the reliability of the terminal S10 of the communication connector can be improved without the fisheye through hole. G is poorly designed (for example, symmetry is not maintained, improper position, etc.), and the pinching phenomenon caused by the crimping of the terminal S10 of the communication connector is caused.

The following describes the forming method of the terminal S10 of the communication connector of the present invention, as follows: First, the preliminary outline of the terminal S10 of the communication connector is punched out on the material with the material thickness T1, and then the preliminary contact tail of the terminal S10 of the communication connector is punched out. Section, at this time, the thickness of the preliminary contact tail section is T1, and then the preliminary contact tail section of the terminal S10 of the communication connector is crushed, so that the thickness of the preliminary contact tail section is formed from T1 to T2 to form a thinned contact tail section. 13, then punch out the fisheye-shaped through hole G. Therefore, it is very simple to make the contact tail portion 13 of the terminal S10 of the communication connector thinner by only one more process of flattening and forming. It should be noted that the manner of forming the terminal S10 of the communication connector is not limited to the above manner, as long as the final result is that the thickness T2 of the contact tail portion 13 is thinner than the thickness T1 of the extension portion 12.

Referring to FIG. 9 and FIG. 10, the communication connector C provided by the present invention is exemplified by an orthogonal connector, but is not limited thereto. The communication connector C is crimped and fixed on the circuit board M and is opposite to another matching communication connector (not shown), and the communication connector C includes a body C1 and a plurality of communication connectors disposed on the body C1. Terminals (S10, S20, S30, S40, S50, S60 shown in Figure 1, the terminals of the remaining communication connectors of Figure 9 are not labeled). However, the communication connector C may include any number of terminals of the communication connector and the remaining terminals (such as the ground terminal), and the terminals of the communication connectors are coupled to the communication connector C. Therefore, the extension 12 of the terminal S10 of the communication connector is substantially bent at a nearly right angle. The contact head section 11 is substantially in the shape of a pointed rod and protrudes from the front side of the body C1. The contact tail section 13 extends from the extension section. The bottom side of the body C1 protrudes for a length, and the extension 12 forms a level difference with the contact tail 13 in the thickness direction. The contact header 11 and the extension 12 of the terminal S10 of the above communication connector are in the form of a matching orthogonal connector, which is not necessarily present if it is not disposed in the orthogonal connector. The contact tail segments (13, 23, 33, 43, 53, 63 as shown in FIG. 9 and the remaining contact tail segments are not labeled) are arranged in a matrix to press fit into the conductive via M1 of the circuit board M (eg Figure 10).

Since the thickness of the contact tail segments is thinner than conventionally known in the present invention, when the conductive vias are pressed into the contact tails, the fisheye-shaped through holes of one or part of the contact tail segments are not designed. Poor, causing the terminal of the communication connector of one or part of the crimping device to be pinched when the crimping is uneven, causing the communication connector to be unstable. Therefore, through the creation, only the contact tail portion of the terminal is thinned, not only maintaining the volume and structural strength of the terminal itself, but also improving the reliability of the terminal crimping to the circuit board, and ensuring the stability of the communication connector and the circuit board. Pick up.

However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the patent protection of the present invention. Therefore, the equivalent technical changes that are made by using the present specification and the contents of the drawings are included in the scope of the present invention.
