Description

Technical Field

[0001] The present invention relates to the technical field of wiring harness cables, and in particular to a wiring harness cable. Background Art

[0002] As a key component of the electrical system, the wiring harness is responsible for connecting the control system and the terminal electrical components. As the nerve of the electrical system, the wiring harness is an effective carrier of various electrical signals, and its reliability plays a vital role. The existing wiring harness is composed of a contact terminal (connector) and a wire and cable crimped together, and then an external plastic-pressed insulator or an external metal shell. When the contact terminal of the wiring harness is connected to the wire and cable, the insulating protective layer on the wire and cable needs to be stripped off first to expose the metal inner core inside the wire and cable, and then the metal inner core and the contact terminal are fixedly connected to make the circuit conductive. In the prior art, wire stripping is generally completed by workers using special stripping tools. The whole process is huge in workload, consumes a lot of manpower, and has very low efficiency.

[0018] 4. By setting a positioning pin in the connector body, when the two connectors are docked together, the lock cores in the two connectors extend out and insert into each other, and cooperate with the positioning pins set in the other connector body to achieve a locking effect, making the connection more convenient.

[0019] To sum up, before use, insert the two cables to be connected into the corresponding connector body, and then directly connect the two connector bodies. Through the mutual cooperation between the connector bodies, the internal lock core is extended, and then the ring cutter and contact connecting rod inside the connector body are controlled at the same time. First, the cable is ring cut to leak the core, and then the metal inner core of the cable is connected to the connector body. When the two connectors are plugged in, the circuit is completed. There is no need to manually strip the cable and then connect it to the connector body, which greatly improves work efficiency. The quality of the ring cutting of the cable using the ring cutter can also be well guaranteed, and it is safer to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It is worth noting that, Figure 1 、 Figure 5 and Figure 6As shown, there are three limiting situations of the limiting ball 7. The first is that the first limiting hole 111 is connected to the limiting through hole 33, that is, the limiting ball 7 limits the linkage frame 3 and the connector body 1. At this time, only the tool holder 21 moves in the linkage frame 3 following the movement of the lock cylinder 2; the second is that the first limiting hole 111, the limiting through hole 33 and the second limiting hole 211 are connected, that is, the limiting ball 7 limits the tool holder 21, the linkage frame 3 and the connector body 1 to a certain extent; the third is that the second limiting hole 211 is connected to the limiting through hole 33, that is, the limiting ball 7 limits the linkage frame 3 and the tool holder 21. At this time, only the linkage frame 3 and the tool holder 21 move following the movement of the lock cylinder 2.

[0039] Preferably, Figure 1 and Figure 5 As shown, the inner cavity 11 is provided with an inner wall surface 17 on one side close to the positioning cover 4 . When the contact point 311 contacts the inner wall surface 7 , the first limiting hole 111 , the limiting through hole 33 and the second limiting hole 211 are just connected.

[0040] Preferably, Figure 1 and Figure 5 As shown, a first inclined surface 34 for pushing the circular cutting knife 22 to close is provided on the inner side of one end of the linkage frame 3 close to the contact link 31 .

[0041] Preferably, Figure 1 and Figure 5 As shown, the connector body 1 is provided with a first limiting surface 18 located at the inner cavity 11 for pushing the contact link 31 to close.

[0042] Preferably, Figure 1 、 Figure 5 and Figure 6 As shown, the end surface of the connector body 1 away from the positioning cover 4 is provided with a second limiting surface 19 for pushing the control rod 6 to rotate.

[0043] Preferably, Figure 1 、 Figure 5 and Figure 6 As shown, both ends of the control rod 6 are spherical, one end extends into the control groove 25 and has a gap with the bottom surface of the control groove 25 when not docked, and the other end is used to contact the second limit surface 19 when docked.

[0044] Working principle:

[0045] When in use, first pass the cable 9 through the perforation to connect it to the positioning cover 4, then tighten the positioning cover 4, and use the contraction effect of the tapered thread to fix the cable 9. At this time, the head of the cable 9 just touches the lock core 2. Figure 1 As shown, the preparation is completed.

[0046] When two cables 9 are to be connected, the plug ends of the two connector bodies 1 are first plugged in. Figure 5 As shown, during the plug-in movement, the second limiting surface 19 touches the control rod 6 and pushes the control rod 6 to swing, thereby overcoming the first spring 24 to pull the lock core 2 outward, so that the front end of the lock core 2 extends. At this time, the limiting ball 7 is simultaneously located in the first limiting hole 111 and the limiting through hole 33 to limit the linkage frame 3, so that the linkage frame 3 remains stationary and the knife holder 21 slides in the linkage frame 3. Therefore, under the action of the first inclined surface 34 on the linkage frame 3, the two circumcision knives 22 are pushed to overcome the first torsion spring 23 and rotate until the two circumcision knives 22 merge to cut the insulation skin outside the cable 9. Figure 5 As shown, when the insulation of the cable 9 is cut, the two connector bodies 1 are continued to be pushed for plugging, thereby driving the lock core 2 to continue to move outward, so that the lock core 2 extends into the lock core groove 13 on the opposite connector body 1. During this process, the lock core 2 contacts the linkage frame 3 and pulls the linkage frame 3 to move together. When the lock core 2 contacts the linkage frame 3, the first limiting hole 111, the limiting through hole 33 and the second limiting hole 211 are just connected, so that the limiting ball 7 moves into the second limiting hole 211, that is, the knife holder 21 and the linkage frame 3 are limited and linked, and then the linkage frame 3 is driven to move when the lock core 2 moves, and when the contact link 31 touches the first limiting surface 18, the first limiting surface 18 pushes the contact link 31 to overcome the second torsion spring 32 to rotate and clamp it in the middle. At the same time, during this process, the circumcision knife 22 always follows the lock core 2 to move outward and is in a closed state, thereby driving the cut insulation to move together. When the metal core of the cable 9 is exposed, the metal core of the cable 9 will be clamped when the contact link 31 is closed to the middle, so that the contact point 311 is connected to the metal core of the cable 9. Since the wiring point 312 and the contact point 311 are connected inside the contact link 31 and the wiring point 312 is connected to the contact probe 51 and the contact pin hole 52 respectively through the wire 8, when the two connector bodies 1 are docked, the corresponding contact probes 51 and the contact pin hole 52 are plugged in, so that the circuits on both sides are connected. At the same time, the lock cores 2 on both sides are just inserted into the lock core grooves 13 of each other. The lock core 2 pushes the second inclined surface on the positioning pin 15 to overcome the second spring 16 and move until the positioning pin 15 is aligned with the positioning hole 26. Under the recovery action of the second spring 16, the positioning pin 15 is pushed into the positioning hole 26 to lock the lock core 2, that is, the two connector bodies 1 are locked, completing the connection of the cables 9 on both sides. Figure 6 shown.

[0047] When the circuit fails and the two connector bodies 1 need to be separated, the second spring 16 is first overcome and the positioning pins 15 on the two connector bodies 1 are pulled outward at the same time, so that the lock cores 2 on both sides are unlocked at the same time. At this time, the lock core 2 is pushed inward by the action of the first spring 24, and then the control rod 6 is driven to rotate to push the second limit surface 19 to separate the two connector bodies 1. At this time, under the action of the limit ball 7, the linkage frame 3 and the tool holder 21 are still in a limited state, so that the lock core 2 moves inward and drives the linkage frame 3 to move together. When the contact link 31 disengages from the first limit surface 18, the second torsion spring 32 drives the contact link 31 to rotate and separate, so that it is disconnected from the metal inner core of the cable 9. At the same time, after the contact link 31 is separated, the contact point 311 contacts the inner wall surface 17 of the connector body 1 for limitation. At this time, the first limit hole 111, the limit through hole 33 and the second limit hole 211 are just connected, and the linkage frame 3 cannot continue to move. Figure 5 As shown, the limiting ball 7 enters the first limiting hole 111 to position the linkage frame 3, and then the lock core 2 continues to move inward under the action of the first spring 24, and the ring cutter 22 is controlled to rotate and separate under the action of the first torsion spring 23, so that the cable 9 is completely loosened and the lock core 2 is also completely retracted, that is, the connector bodies 1 on both sides are completely separated, and then the positioning cover 4 is unscrewed to remove the cable 9 for maintenance, completing the disassembly of the connector body 1.
