Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector that pierces a terminal type.

The terminal connector is a basic component in the field of electronic communication as a bridge for electrically connecting a cable and a plug covering a plurality of core wires. A common connector is a piercing connector, that is, a connector having a piercing terminal, which includes a socket body, a full wire portion, and two outer covers. Wherein, the socket main system is used for plugging the plug, and a plurality of piercing terminals are arranged thereon for piercing the core wire. The entire line is used as a plug-in cable and can hold the core wire. The outer cover is pivoted on the socket body as a cover to protect the entire line. In operation, the user first pivots the two outer covers, and inserts the socket body into which the plug is inserted into the entire line portion to which the core wire is fixed. Then, the two outer covers are pivotally closed, and the whole line portion is coupled to the socket body in a manner of directly pressing the top surface of the whole line portion, so that the cable is fixed to the connector, and at the same time, the core wire is pierced, and the terminal is pierced. Electrical contact with the core wire to complete the assembly of the connector and the cable.

Due to the advancement of technology, the requirements for communication quality are getting higher and higher, and therefore, the connection quality requirements for connectors are becoming more and more stringent. However, in the above conventional connector, during the process of pivoting the outer cover, the force applied by the outer cover to the entire line portion is not uniform, and the whole line portion is liable to be tilted and pressed against the socket body in a wrong manner, so that the core wire is not pierced. Completely waiting for the problem to occur and failing to reach the predetermined transmission capacity not only directly affects the quality of the communication, but also has to re-disassemble the line and then perform the above-mentioned puncture process, which seriously affects the work efficiency. It can be seen that the traditional connector has been unable to meet the demand for connection quality at this stage.

The present invention is to provide an electrical connector, thereby solving the problem that the conventional piercing connector has a coupling failure during assembly.

The electrical connector disclosed in the present invention comprises a piercing terminal block, a terminal pressing member and a gland assembly. The terminal pressing member is detachably mounted on the piercing terminal block. The terminal pressing member has two pressure receiving faces opposed to each other. The two pressure receiving faces are pierced away from the terminal block. The gland assembly is pivoted to the piercing terminal block and has an inner wall surface and two pressing protrusions protruding from the inner wall surface and corresponding to the two pressure receiving surfaces. Each of the pressing bumps includes at least two pressing portions. The pressing portions of the two pressing protrusions are pivoted to the two pressing surfaces of the terminal pressing member to have the same pivoting angle, so that when the two pressing protrusions press the two pressure receiving surfaces of the terminal pressing member, the two pressing convex portions The block maintains four points of contact with the two pressure receiving faces.

According to the above-mentioned electrical connector of the present invention, due to the design of the two pressing protrusions on the gland assembly, each of the pressing protrusions can contact the terminal pressing member at least in two points, that is, the gland assembly The terminal pressing member is pressed by the contact method of four or more points to ensure uniform compression of the terminal pressing member, and can be pressed against the piercing terminal block in a predetermined manner to prevent the terminal pressing member from being stressed during the puncturing process. The problem of uneven tilting and inaccurate coupling, in addition to achieving the predetermined electrical connection effect of the electrical connector, can also reduce the situation in which the re-disassembly of the assembly is required due to incomplete puncture.

Next, the manner of use of the electrical connector 1 will be described. First, please refer to FIG. 3, which is a schematic view of a terminal pressing member and a cable connected thereto according to an embodiment of the present invention. The user can first pass the cable 90 through the through hole 27 of the terminal pressing member 20, and clamp the core wire 93 in the cable 90 to the clamping groove 23 of the terminal pressing member 20, respectively. Thereby, each of the core wires 93 is temporarily fixed to the terminal pressing member 20, and its positional arrangement can be maintained in a state corresponding to the piercing of the terminal 120. It can be understood that, by the aforementioned design having the projections 29 at the perforations 27, the insulating layer 91 peeled off from the cable 90 can be blocked from passing through the through holes 27 to avoid interference with the core wires 93 for subsequent operations.

Next, please refer to Figures 4~5C. 4 is an exploded view of an electrical connector and a cable and a plug connected thereto according to an embodiment of the present invention, and FIG. 5A is a side view of the electrical connector according to an embodiment of the present invention, 5B is a side cross-sectional view of an electrical connector in accordance with an embodiment of the present invention, and FIG. 5C is another side cross-sectional view of the electrical connector in accordance with an embodiment of the present invention. Here, in order to simplify the description, the cable 90 and the plug 97 will be omitted in FIG. 5A to 5C, and only the first gland 310 will be cut in FIG. 5C.

As shown in FIG. 4, when the terminal crimping member 20 and the cable 90 are to be inserted into the terminal block 111 of the terminal block 10, the core wire 93 clamped to the clamping slot 23 can be correspondingly coupled to the terminal block 111. Pierce the terminal 120. Next, as shown in FIGS. 5A to 5C, pivoting the first gland 310 forces the terminal pressing member 20 to press against the piercing terminal block 10. Specifically, during the process of pivoting the first gland 310 to the terminal pressing member 20, the two pressing protrusions 313 on the inner wall surface 311 of the first gland 310 are simultaneously pressed against the terminal pressing member 20 at the same time. Two pressure receiving faces 21. In detail, during the process of pivoting the pressing protrusion 313 to the pressure receiving surface 21 of the terminal pressing member 20, the first pressing surface S1 of the first pressing portion 3131 pivots to the pivot of the pressure receiving surface 21. The pivoting angle θ1 and the second pressing surface S2 of the second pressing portion 3133 are pivoted to the pivoting angle θ2 of the pressure receiving surface 21, that is, the surfaces of the first pressing portion 3131 and the second pressing portion 3133 are pivoted. The pivoting amount to the pressure receiving surface 21 is the same, so that the first pressing portion 3131 and the second pressing portion 3133 of the pressing protrusion 313 simultaneously touch the pressure receiving surface 21 of the terminal pressing member 20. That is, the single pressing bump 313 first touches the pressure receiving surface of the terminal pressing member 20 in a two-point contact manner. Therefore, by the arrangement of the two pressing protrusions 313, the single first gland 310 can touch the terminal pressing member 20 in four-point contact, so that the first gland 310 is pressed from the initial pressure to the terminal. In the case of the member 20, the terminal pressing member 20 is pressed in a manner of a relatively even force application, so that the force applied to the terminal pressing member 20 by the first pressing cover 310 is evenly distributed, thereby avoiding the unevenness of the terminal pressing member 20 due to the force. The terminal block 10 is punctured at an oblique angle. Thereby, it can be ensured that the piercing terminal 120 can surely cut through the core wire 93 clamped on the clamping groove 23 of the terminal pressing member 20, thereby reducing the problem that the piercing terminal 120 is not coupled with the core wire 93 to obtain the core wire 93 and A predetermined electrical connection between the plugs 97. In addition, compared with the conventional design that some electrical connectors have to pierce the core wires by pivoting the two covers, the present invention can only apply a uniform pressure to the terminal press members by pivoting only one single gland. Can significantly reduce the impact of human factors on assembly.

Next, please refer to FIG. 6, which is another side view of the electrical connector and the cable and plug connected thereto according to an embodiment of the present invention. Finally, the user can pivot the second gland 320 to select the two latching blocks 323 on the inner side walls 321 of the second gland 320 to be engaged with the positioning bumps 317 of the first gland 310. A gland 310 is clamped and fixed between the second gland 320 and the piercing terminal block 10. In addition, as can be seen from FIG. 6 and the multiple reference FIG. 1, the cable 90 can be clamped between the second gland 320 and the first gland 310 to achieve the effect of the wire harness.

In addition, a plurality of positioning bumps 317 are provided in the embodiment for the second gland 320 to be engaged, so that the second gland 320 can be fastened and fixed to different cover positions relative to the first gland 310 for The user can clamp the cable 90 of different thickness according to actual needs, or adjust the beaming effect of different degrees. However, the present invention is not limited to the number of positioning bumps 317. For example, in other embodiments, the number of the positioning bumps 317 on each of the outer sidewalls 315 of the first gland 310 may be only one, two or four or more.

In addition, in the embodiment, the first pressing portion 3131 and the second pressing portion 3133 of the pressing protrusion 313 are integrally formed, and the first pressing surface S1 and the second pressing surface S2 are a continuous curved surface. However, this new model is not limited to this. In fact, as long as it helps to make the first gland 310 touch the terminal pressing member 20 in four-point contact, or as long as it helps to make the first gland 310 to the terminal pressing member 20 The design of evenly distributed force is within the scope of the present invention. For example, in other embodiments, the first pressing portion 3131 and the second pressing portion 3133 of each pressing protrusion 313 may also be two independent structures, and the first pressing surface S1 and the second pressing surface are respectively pressed. The face S2 may also be a bevel. Or in other embodiments, the number of the first pressing portion 3131 and the second pressing portion 3133 in each of the pressing protrusions 313 may be plural. In this design, each pressing protrusion 313 pivots. When the pressure is applied to the terminal pressing member 20, it is not limited to three or four points or more, that is, the first pressing cover 310 can also press the terminal pressing in a total of six or more points. The member 20 makes the force distribution of the first gland 310 to the terminal pressing member 20 more uniform.

In summary, the electrical connector proposed by the present invention, due to the design of two pressing protrusions on the gland assembly, each of the pressing protrusions can contact the terminal pressing member at least in two points, that is, The gland assembly touches the terminal pressing member with more than four points of contact, which ensures that the terminal pressing member is uniformly pressed, and can be pressed against the piercing terminal block in a predetermined manner to avoid the terminal pressing member during the puncture process. The problem of tilting due to uneven force and causing inaccurate coupling, in addition to achieving the predetermined electrical connection effect of the electrical connector, can also reduce the need for re-disassembly and assembly due to incomplete puncture.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the present invention.
