[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a non-detachable connector with line positioning. The non-detachable connector with line positioning includes a housing 1. The housing 1 has a plurality of evenly spaced wiring grooves 101. Each wiring groove 101 has a pin 2 fixedly installed in it. The housing 1 has a plurality of wiring holes 102 communicating with the wiring grooves 101. One end of the pin 2 inserted into the wiring groove 101 is fixedly installed with a locking copper block 3. The end of the locking copper block 3 facing the wiring hole 102 has a mating hole 301. The top of the locking copper block 3 has a threaded locking hole 302 communicating with the mating hole 301. The housing 1 is equipped with a pressure cap 4 for pressing and securing the wire harness connector. The housing 1 has T-shaped grooves 103 symmetrically spaced on both sides of the wiring grooves 101. Wire securing components 5 are installed on the T-shaped grooves 103.

[0024] The cover 4 includes a cover plate 41. One end of the cover plate 41 is provided with a plurality of protruding plates 43 for sealing the wiring groove 101. Each of the protruding plates 43 is equipped with a crimping screw 44 that is threadedly connected to the threaded locking hole 302.

[0025] The housing 1 has a lower conduit 6 fixedly installed on the outside of several wiring holes 102. Two pads 7 are fixedly installed inside the lower conduit 6. The pads 7 have cable trays 701. The cable fixing assembly 5 includes a plug plate 51. The plug plate 51 has T-shaped feet 52 on both sides that are inserted into the T-shaped slots 103. The bottom outer side of the plug plate 51 is fitted with an upper conduit 53 that aligns with the lower conduit 6. The upper conduit 53 has a pressure plate 54 that aligns with the cable trays 701. The top outer side of the plug plate 51 has a cable entry mark slot 55. There are three sets of connecting springs 56. One end of the three sets of connecting springs 56 is fixedly connected to the top of the inner cavity of the upper conduit 53, and the other end of the three sets of connecting springs 56 is fixedly connected to the pressure plate 54.

[0026] It should be noted that during use, the wire to be connected is passed through the lower conduit 6, the wiring hole 103 and the docking hole 301 and inserted into the threaded locking hole 302. Then, the cover plate 41 is placed on the housing 1, and the crimping screw 44 is screwed into the threaded locking hole 302. The wire is then connected to the locking copper block 3 to complete the wiring. In the later use, the pin 2 can be directly inserted into the slot of the corresponding other terminal. After the connection, the wire fixing component 5 is used to prevent the connected wire from coming loose and to press it firmly.

[0027] Specifically, during the pressing process, the insert plate 51 is inserted into the T-slot 102 using the T-shaped foot 52 until the upper conduit 53 and the lower conduit 6 are aligned. During pressing, the pressure plate 54 is used to press and secure the wires placed on the pad block 7 cable tray 701 to prevent them from accidentally falling off.

[0028] It is worth noting that the plug plate 51 is also equipped with a horizontal plate to cover the protruding plate 43, which can protect the connected parts and prevent accidental electric shock.

[0029] Furthermore, to facilitate the positioning and marking of incoming and outgoing lines, the cover plate 41 is evenly equipped with outgoing line marking slots 42 corresponding to several wiring slots 101. In this way, the outgoing lines can be marked with cards and then inserted into the outgoing line marking slots 42 for easy marking. Then, in conjunction with the incoming line marking slots 55, the incoming wires can be similarly marked with cards and then inserted into the incoming line marking slots 55 to complete the positioning of the lines, which is convenient for subsequent connection positioning and troubleshooting of the lines.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 4 The upper tube 53 and the lower tube 6 are provided with mating external threads and are threadedly connected with locking nuts 8;

[0031] It should be noted that after the upper conduit 53 and the lower conduit 6 are aligned, the locking nut 8 can be used to lock the upper conduit 53 and the lower conduit 6 together, thereby improving the stability of the pressure plate 54 in securing the wire.

[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 The number of cable trays 701 is three sets, and the pressure plate 54 is fixedly installed on the upper cable tube 53 by connecting spring 56;

[0033] It should be noted that this arrangement allows the wires to be folded into an S-shape and routed out of the cable trays 701 when they pass over the two pads 7, thus improving the tightness of the pressure plate 54 in securing the wires.

[0034] The working principle of the anti-disconnection connector with line positioning provided by this utility model is as follows:

[0035] In use, the wire to be connected is passed through the lower conduit 6, the wiring hole 103, and the mating hole 301 and then into the threaded locking hole 302. The cover plate 41 is then placed on the housing 1, and the crimping screw 44 is screwed into the threaded locking hole 302. The wire is then mated with the locking copper block 3. After mating, to facilitate the marking of the connected and disconnected lines, the disconnected line is marked with a card and inserted into the outgoing line marking slot 42 for easy marking. This is then combined with the incoming line marking slot 55, and the connected wire is similarly marked with a card. Insert the pin into the inlet marking slot 55 to complete the line positioning, which facilitates the connection and positioning of the line in the later stage. After the wiring marking is completed, the pin 2 can be directly inserted into the slot of the corresponding other terminal block. After the connection is completed, the wire fixing component 5 is used to prevent the connected wire from falling off. Specifically, when fixing, the plug plate 51 is inserted into the T-slot 102 with the T-shaped foot 52 until the upper wire tube 53 and the lower wire tube 6 are aligned. When pressing, the pressure plate 54 is used to fix the wire placed on the pad block 7 cable tray 701 to prevent the wire from falling off accidentally.

[0036] Furthermore, when the wire is introduced into the wiring hole 103 from the lower conduit 6, the wire passes over the two pads 7 and is arranged and folded into an S-shape by the three sets of wiring channels 701 to be led out from the wiring channels 701. This makes it easier to improve the tightness of the pressure plate 54 in pressing the wire.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
