After the conductor part of the power cord is inserted into the power terminal, the upper cover is buckled on the lower cover, and finally the fastening screw is screwed between the upper cover and the lower cover, so that the power cord can be fixed between the two clamping blocks of the upper cover and the lower cover. However, this wire fixing structure has the following shortcomings in actual use: since the fixing operation of the power cord and the power terminal after wiring is achieved only by the clamping force of the clamping blocks on the lower cover and the upper cover, when external force acts on the power cord, the main body of the power cord is prone to shaking and displacement between the lower cover and the upper cover, and the conductor part of the power cord is prone to move in the power terminal, resulting in poor contact and falling off, which reduces the safety and stability of the actual use of the power cord after it is fixed in the electrical connector.
[0004] In view of this, it is particularly important to design and manufacture a fixed wire structure that can comprehensively fix the main body and the conductor part of the power cord and reduce the problem of accidental falling off of the power cord under stress, and to apply it to electrical connectors. Utility Model Content

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1-4The utility model provides a technical solution: an electric connector wire fixing structure, comprising a shell 1, a plurality of power terminals 101 equidistantly fixed inside the shell 1, a wire groove 103 opened at the right end of the shell 1 and corresponding to the plurality of power terminals 101, a lower cover 2 integrally fixed to the bottom of the right end of the shell 1, an upper cover 3 detachably mounted on the upper end of the lower cover 2, a wire clamping block 8 fixed to the lower cover 2 and the middle part of the inner side of the upper cover 3, a power cord 4 fixed between the two wire clamping blocks 8, and a wire 401 installed on the power cord 4 and plugged with the plurality of power terminals 101, a wire locking portion for preventing the wire 401 from falling off and limiting it between the power terminals 101 and the wire groove 103 is provided on the shell 1, and a wire clamping portion for auxiliary clamping of the power cord 4 fixed between the two wire clamping blocks 8 is provided between the lower cover 2 and the upper cover 3.
[0029] Specifically, Figure 2 and Figure 3 As shown, the wire locking portion includes a transverse slot 104 opened on the shell 1 and passing through multiple wire slots 103, a transverse insertion block 7 movably installed on the inner side of the transverse slot 104, and a lower convex pressure block 701 equidistantly fixed at the lower end of the transverse insertion block 7 and abutting against the outer walls of multiple wires 401. When the transverse insertion block 7 slides horizontally into the transverse slot 104, the transverse insertion block 7 generates a downward extrusion force to squeeze the wire 401 downward and fix it in the wire slot 103.
[0030] The inner side of the wire slot 103 is integrally fixedly connected with a support block 105 that protrudes upward and abuts against the outer wall of the wire 401 , which can support and lift the wire 401 in the wire slot 103 and improve the fixing effect of the wire 401 in the wire slot 103 .
[0031] Specifically, Figure 2 and Figure 3 As shown, the wire clamping part includes two inner screw blocks 201 symmetrically fixed on the front and rear ends of the lower cover 2, a fastening screw 5 installed on the inner side of the two inner screw blocks 201 through threaded engagement and passing through the upper cover 3, two slide grooves 202 symmetrically arranged between the lower cover 2 and the wire clamping block 8, and a sliding lock block 6 movably arranged on the inner side of the slide groove 202 and located between the power cord 4 and the fastening screw 5. When the fastening screw 5 is screwed inwardly into the inner screw block 201, on the one hand, the upper cover 3 can be locked and fixed on the lower cover 2, and on the other hand, the sliding lock block 6 can be pushed to squeeze the power cord 4 backward in the slide groove 202, wherein the sliding lock block 6 is provided with an inner concave clamping groove 601 in the shape of an isosceles triangle structure toward one end of the power cord 4, which, on the one hand, can guide the middle part of the sliding lock block 6 to the center of the power cord 4, and on the other hand, can increase the contact area between the power cord 4 and the sliding lock block 6, thereby improving the stability of the sliding lock block 6 in auxiliary locking and fixing the power cord 4 between the two wire clamping blocks 8.
[0032] Specifically, Figure 1-3As shown, the front and rear ends of the shell 1 are symmetrically fixedly connected with fixing buckles 102, and a mounting hole is opened in the middle of the fixing buckle 102. The setting of the fixing buckle 102 and the mounting hole makes it convenient for the shell 1 to be installed and fixed outside the connecting seat by fasteners after the electrical connector is inserted.
[0033] Working principle: When the power cord 4 needs to be fixed inside the electrical connector, the first step is to insert the wire 401 of the power cord 4 into the power terminal 101 through the wire groove 103, and then the horizontal insertion block 7 can be horizontally slid into the horizontal slot 104. When the horizontal insertion block 7 is completely slid into the horizontal slot 104, the lower convex pressing block 701 on the horizontal insertion block 7 can press the wire 401 downward and fix it on the support bracket 105. At this time, the wire 401 will be stably locked between the power terminal 101 and the wire groove 103; the second step is to adjust the power cord 4 to the lower cover 2 and the upper cover 2. After the cover 3 is between the clamping blocks 8, the two sliding blocks 6 can be placed in the sliding groove 202 of the lower cover 2, and the upper cover 3 can be closed on the top of the lower cover 2; the third step: the fastening screw 5 is passed inward through the reserved hole on the upper cover 3, and then screwed into the inner screw block 201 through the thread. At this time, the fastening screw 5 can move inward, contact and squeeze the sliding block 6 to move inward, and the two sliding blocks 6 can squeeze the power cord 4 between the two clamping blocks 8 inward, clamp the main part of the power cord 4, and prevent the power cord 4 from being pulled and moved between the lower cover 2, the upper cover 3 and the clamping blocks 8.
