At this time, the emergence of switches has greatly solved this situation. It can provide more connection ports for sub-networks to connect more devices. However, when using existing switches, the wiring terminals of the switches are prone to loosen after the connection heads are inserted, resulting in unstable network connections for the connected devices. Content of the Utility Model

[0004] The purpose of the utility model is to provide a switch for preventing wire harness loosening, so as to solve the problem that the wiring terminals of the switch are prone to loosen after the connection heads are inserted, resulting in unstable network connections for the connected devices as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution. A switch for preventing wire harness loosening includes:

[0006] A box body, including a network switch, and a connection head is inserted and connected to the surface of the network switch;

[0007] A limiting mechanism, including a protective shell, which acts on the surface of the network switch. A limiting block is fixedly connected to the surface of the protective shell, and a fixing block is fixedly connected to the surface of the protective shell. A connection block is fixedly connected to the surface of the network switch, and a rotating rod is fixedly connected to the surface of the network switch. A connecting rod is fixedly connected to the surface of the connection block, and a torsion spring is fixedly connected to the surface of the connection block. A limiting groove is fixedly connected to the surface of the network switch, and a limiting rod is rotatably connected to the surface of the limiting groove;

[0008] A supporting mechanism, including a butting plate, which acts on the lower surface of the network switch. A slot is opened on the surface of the butting plate, and a turntable is fixedly connected to the surface of the butting plate. A placement groove is opened on the lower surface of the network switch, and a support rod is rotatably connected to the inside of the placement groove.

[0009] Preferably, the limiting blocks are evenly distributed on the surface of the protective shell, and both the limiting blocks and the fixing blocks are in an "L" shape.

[0010] Preferably, the rotating rod is rotatably connected to the surfaces of the connecting rod and the connecting block, and the protective shell is rotatably connected to the surface of the network switch through the rotating rod.

[0011] Preferably, both ends of the torsion spring are fixedly connected to the surface of the connecting block and the inside of the rotating rod. The torsion spring is wound around the surface of the connecting rod, and the rotating rod is rotatably connected to the surface of the network switch through the torsion spring.

[0012] Preferably, a semicircular channel is formed on the surface of the limiting groove. The limiting rod is rotatably connected to the surface of the network switch through the limiting groove, and the protective shell is fixedly connected to the front end of the limiting rod through the fixing block.

[0013] Preferably, the abutting plates are symmetrically distributed in two groups on the lower surface of the network switch. The slots are evenly formed on the surface of the abutting plates, and the turntable is rotatably connected to the surface of the network switch.

[0014] Preferably, the support rod is rotatably connected to the surface of the network switch, and the network switch is fixedly connected to the surface of the abutting plate through the support rod.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. Through the connection of the protective shell and the rotating rod, the connection of the connecting block and the connecting rod, when the rotating rod rotates, it drives the protective shell to rotate. The connection of the torsion spring with the connecting block and the rotating rod causes the torsion spring to deform and generate elastic potential energy, enabling the protective shell to have an automatic reset effect, ensuring that when the protective shell is closed, it will not rotate due to external forces. The setting of multiple groups of limiting blocks fits on the surface of the wiring head, thereby limiting each wiring head inserted into the surface of the network switch. The "L" - shaped design of the limiting block is such that the middle section of the limiting block is attached to the surface of the wiring head, and the bottom end abuts against the surface of the network switch, avoiding the direct action of the limiting block on the surface of the wiring head. Excessive force is likely to damage the contact between the network switch and the wiring head. Finally, the connection of the fixing block and the limiting rod can fix the position of the protective shell after it is opened, without affecting the insertion of the wiring head, achieving the prevention of wire harness loosening and wiring head dropping, while also protecting the wiring end.

[0017] 2. Through the connection of the abutting plate and the turntable, when it is necessary to change the inclination angle of the network switch, by rotating the support rod and rotating the abutting plate, and inserting the support rod into the slot, the inclination angle of the network switch can be adjusted. Moreover, the support rod can support the network switch. The design of two groups of abutting plates improves the support effect and ensures the stability of the network switch after it is lifted. Moreover, when not in use, the support rod can also be retracted into the placement groove, and the abutting plate can be rotated to the surface of the network switch to act as a footrest, achieving the effect of keeping the wiring end of the network switch facing upward and not occupying space when not in use.

DETAILED DESCRIPTION

[0024] 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 in 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.

[0025] See also Figures 1-5 , an embodiment provided by the utility model:

[0026] A switch for preventing a wire harness from loosening, comprising:

[0027] The box body includes a network switch 1. The surface of the network switch 1 is plugged and connected with a wiring head 11, which is used to plug the network switch 1 to ensure the normal use of the network switch 1. The network switch 1 and the wiring head 11 are both existing products and are not used as technical protection points of this application. No excessive description is made here.

[0028] The limiting mechanism includes a protective shell 2 which acts on the surface of the network switch 1 for protecting the wiring ports. A limiting block 21 is fixedly connected to the surface of the protective shell 2 for limiting the wiring head 11 connected to the surface of the network switch 1. A fixing block 22 is fixedly connected to the surface of the protective shell 2 for hanging on it by rotating the limiting rod 28 to fix the position of the protective shell 2 after it is opened. A connecting block 23 is fixedly connected to the surface of the network switch 1 for connecting the network switch 1, the connecting rod 25 and the torsion spring 26. A rotating rod 24 is fixedly connected to the surface of the network switch 1 for connecting the protective shell 2 and the torsion spring 26 so that the protective shell 2 can rotate on the surface of the network switch 1. A connecting rod 25 is fixedly connected to the surface of the connecting block 23 for winding the torsion spring 26 and enabling the rotating rod 24 to rotate. A torsion spring 26 is fixedly connected to the surface of the connecting block 23 for providing a reset effect so that the protective shell 2 can close itself after being opened. Due to the existence of the torsion spring 26, the protective shell 2 and the limiting block 21 can fit on the surface of the wiring head 11 to prevent the wiring head 11 from loosening. A limiting groove 27 is fixedly connected to the surface of the network switch 1 for the limiting rod 28 to rotate. At the same time, the semicircular groove opened on the surface limits the rotation angle of the limiting rod 28 so that it is always located in the upper half area of the network switch 1. The limiting rod 28 is rotatably connected to the surface of the limiting groove 27. After the protective shell 2 is completely opened, rotate the limiting rod 28 and hang the front section at the fixing block 22 to fix the position of the protective shell 2;

[0029] The supporting mechanism includes a butting plate 3 which acts on the lower surface of the network switch 1 for adjusting the angle of the wiring end of the network switch 1. A slot 31 is opened on the surface of the butting plate 3 for inserting a supporting rod 34 to support the network switch 1. The setting of multiple groups of slots 31 can adjust the network switch 1 to different angles. A turntable 32 is fixedly connected to the surface of the butting plate 3 for connecting the butting plate 3 and driving the butting plate 3 to rotate. When the butting plate 3 is not in use, it can be flush with the bottom of the network switch 1. A placement groove 33 is opened on the lower surface of the network switch 1 for placing the supporting rod 34. The supporting rod 34 is rotatably connected inside the placement groove 33. After rotation, the front end is inserted into different positions of the slot 31 to change the inclination angle of the network switch 1 and support the position of the network switch 1.

[0030] Further, the limiting blocks 21 are evenly distributed on the surface of the protective shell 2 to limit each wiring head 11 inserted into the surface of the network switch 1. Both the limiting block 21 and the fixing block 22 are in an "L" shape. The "L" shape design of the limiting block 21 is that the middle section of the limiting block 21 restricts the position of the wiring head 11 and the bottom end abuts against the surface of the network switch 1 to avoid the limiting block 21 directly acting on the surface of the wiring head 11. Excessive force is likely to damage the contact between the network switch 1 and the wiring head 11.

[0031] Furthermore, the rotating rod 24 is rotationally connected to the surfaces of the connecting rod 25 and the connecting block 23. The connecting rod 25 penetrates through the surface of the rotating rod 24, enabling the rotating rod 24 to rotate. The protective shell 2 is rotationally connected to the surfaces of the rotating rod 24 and the network switch 1. When the rotating rod 24 rotates, it drives the protective shell 2 to rotate, thereby opening and closing the protective shell 2 for the normal insertion of the connection head 11.

[0032] Furthermore, both ends of the torsion spring 26 are fixedly connected to the surface of the connecting block 23 and the interior of the rotating rod 24. The two ends of the torsion spring 26 are respectively fixed to two structures, enabling the torsion spring 26 to produce a reset effect. The torsion spring 26 is wound around the surface of the connecting rod 25 for resetting. The rotating rod 24 is rotationally connected to the surface of the network switch 1 through the torsion spring 26. After the protective shell 2 is opened, due to the existence of the torsion spring 26, the protective shell 2 will automatically reset and will not move without external force, which is used to limit the position of the connection head 11.

[0033] Furthermore, a semi-circular channel is provided on the surface of the limiting groove 27, restricting the rotation angle of the limiting rod 28 so that it always remains in the upper half area of the network switch 1. The limiting rod 28 is rotationally connected to the surface of the network switch 1 through the limiting groove 27. The protective shell 2 is fixedly connected to the front end of the limiting rod 28 through the fixing block 22. After the protective shell 2 is fully opened, rotating the limiting rod 28 and hanging the front section at the fixing block 22 can fix the position of the protective shell 2.

[0034] Furthermore, the abutting plates 3 are symmetrically distributed in two groups on the lower surface of the network switch 1. The design of the two groups of abutting plates 3 not only improves the support effect but also ensures the stability of the network switch 1 after being lifted. The slots 31 are evenly provided on the surface of the abutting plates 3 for inserting the support rods 34 to support the network switch 1. The setting of multiple groups of slots 31 can adjust the network switch 1 to different angles. The turntable 32 is rotationally connected to the surface of the network switch 1 and can drive the abutting plates 3 to rotate. When the abutting plates 3 are not in use, they can be flush with the bottom of the network switch 1 and be retracted to act as feet, without occupying space.

[0035] Furthermore, the support rod 34 is rotationally connected to the surface of the network switch 1. After rotation, the front end is inserted into different positions of the slots 31 to change the inclination angle of the network switch 1. The network switch 1 is fixedly connected to the surfaces of the support rod 34 and the abutting plate 3. After adjusting the inclination angle of the network switch 1, the rotating rod 24 is inserted into the slot 31 to achieve the effect of supporting the position of the network switch 1.

[0036] Working principle: When using the network switch 1, multiple sets of terminal connectors 11 need to be inserted into the connection terminals of the network switch 1. If the position of the network switch 1 is relatively low and it is not convenient to insert, the network switch 1 can be lifted, the support rod 34 can be turned out, and the abutting plate 3 can be rotated so that all the slots 31 on the surface of the abutting plate 3 are exposed. After determining the inclination angle of the connection port of the network switch 1, the support rod 34 is inserted into the corresponding slot 31, and the other set of abutting plates 3 is processed in the same way to complete the adjustment of the inclination angle of the network switch 1. Then, by opening the protective shell 2, at this time, the torsion spring 26 deforms, the limiting rod 28 is rotated, and the front end of the limiting rod 28 is hooked on the fixed block 22 on the surface of the protective shell 2. After fixing the opening position of the protective shell 2, the terminal connector 11 can be inserted. After the insertion is completed, the limiting rod 28 is separated from the fixed block 22, and the protective shell 2 is lowered. The protective shell 2 automatically resets due to the deformation of the torsion spring 26, and the limiting block 21 is attached to the surface of the terminal connector 11. Then, the network switch 1 is slightly lifted, the support rod 34 is rotated, and after it is turned back to the placement groove 33, the abutting plate 3 is rotated and attached to the bottom of the network switch 1, and then the network switch 1 can be placed back in place.
