With the increasing level of industrial automation and the increasingly strict and precise requirements for industrial control, the usage of wiring terminals is gradually increasing. With the development of the electronics industry, the application range of wiring terminals is becoming wider and wider.

[0003] When connecting existing wiring terminals, it is necessary to hold the wire head to complete the subsequent wiring and pressing work. However, the operation is rather inconvenient during wiring, and it is easy to have an unstable connection. Moreover, only fixed by the wire head, the connection between the wire and the wiring terminal head is likely to become loose when the wire is pulled during use, resulting in poor contact. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the hand-held wiring operation is inconvenient and it is easy to loosen during use.

[0005] To solve the above problems, the following technical solutions are adopted in the utility model: The wiring terminal for preventing loosening proposed by the utility model includes a housing. An inlet for the wire is opened at the rear side of the housing. It further includes a wiring mechanism, a fixing mechanism, and an anti-loosening mechanism. The wiring mechanism is arranged on the other side inside the housing. The fixing mechanism is arranged at the middle position inside the housing. The fixing mechanism includes a base and a wire pressing plate. The base is fixedly connected to the inner side of the housing. The wire pressing plate is movably connected to the base. Anti-loosening mechanisms are arranged on both the left and right sides of the fixing mechanism. The anti-loosening mechanism includes a guiding column and a spring. The lower end of the guiding column is fixedly connected to the upper part of the base. The middle section of the guiding column is slidably connected to the wire pressing plate and penetrates through the wire pressing plate. A limiting block is fixedly arranged at the upper end of the guiding column. One end of the spring is fixedly connected to the limiting block, and the other end of the spring is fixedly connected to the upper part of the wire pressing plate. The spring is sleeved outside the guiding column.

[0006] Furthermore, the wiring mechanism includes a wiring head and a pressing screw. The wiring head is fixedly connected to the front part inside the housing. A wiring opening is opened at the rear side of the wiring head. A pressing bolt hole is opened at the upper side of the wiring head. The pressing bolt hole is connected to the wiring opening in a through manner. The pressing screw is in threaded connection with the pressing bolt hole and penetrates through the pressing bolt hole.

[0007] Furthermore, the fixing mechanism further includes a fixing bolt hole and a fixing screw. A wire pressing opening is opened at the upper part of the base. A wire pressing opening is opened at the lower side of the wire pressing plate. The wire pressing opening on the base and the wire pressing opening on the wire pressing plate are arranged oppositely.

[0008] Furthermore, a pulling block is fixedly arranged on the upper part of the wire pressing plate.

[0009] Further, the fixing bolt holes are sequentially arranged through the pulling block, the wire pressing plate and the base, and the fixing screw is in threaded connection with the fixing bolt hole.

[0010] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0011] The anti-loosening wiring terminal proposed in this solution can temporarily press the wire head during the wiring process by arranging a fixing mechanism in the housing and an anti-detaching mechanism on the fixing mechanism, which is convenient for subsequent wiring operations. And the device after wiring is fixed multiple times by the fixing screw, avoiding the loosening of the wiring during use. Description of the Drawings

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a kind of anti-loosening wiring terminal proposed by the utility model includes a housing 1. An inlet port 101 is provided at the rear side of the housing 1. It further includes a wiring mechanism 2, a fixing mechanism 3 and an anti-detaching mechanism 4. The wiring mechanism 2 is arranged on the other side inside the housing 1. The fixing mechanism 3 is arranged at the middle position inside the housing 1. The fixing mechanism 3 includes a base 301 and a wire pressing plate 302. The base 301 is fixedly connected to the inner side of the housing 1. The wire pressing plate 302 is movably connected to the base 301. Anti-detaching mechanisms 4 are arranged on both the left and right sides of the fixing mechanism 3. The anti-detaching mechanism 4 includes a guide post 401 and a spring 403. The lower end of the guide post 401 is fixedly connected to the upper part of the base 301. The middle section of the guide post 401 is slidably connected to the wire pressing plate 302 and penetrates through the wire pressing plate 302. A limit block 402 is fixedly arranged at the upper end of the guide post 401. One end of the spring 403 is fixedly connected to the limit block 402. The other end of the spring 403 is fixedly connected to the upper part of the wire pressing plate 302. The spring 403 is sleeved outside the guide post 401.

[0019] As Figure 1 and Figure 2 shown in the figure, the wiring mechanism 2 includes a wiring head 201 and a pressing screw 204. The wiring head 201 is fixedly connected to the front part inside the housing 1. A wiring port 202 is provided at the rear side of the wiring head 201. A pressing bolt hole 203 is provided on the upper side of the wiring head 201. The pressing bolt hole 203 is connected to the wiring port 202 in a through manner. The pressing screw 204 is in threaded connection with the pressing bolt hole 203 and penetrates through the pressing bolt hole 203 for wiring.

[0020] As Figure 2 and Figure 3 shown in the figure, the fixing mechanism 3 further includes a fixing bolt hole 304 and a fixing screw 305.
