Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a tubular plug-in terminal with an anti-dropping function. Background Art

[0002] Tubular terminals are common connectors on electrical equipment. Common tubular terminals usually include a flat end and a wiring end. The flat end is provided with a connection hole, and the wiring end is provided with a wiring hole for connecting the cable. When wiring the tubular terminals, the cable needs to be inserted into the wiring hole, and then crimped using a crimping pliers or the like. When crimping the tubular terminals, the rear end of the cable needs to be fixed to prevent the cable from falling off from the wiring hole. Most of the existing methods are that the operator holds the cable with one hand and operates the hydraulic pliers with the other hand to pre-crimp the tubular terminal and the cable to ensure that the cable will not fall off, and then operates the hydraulic pliers with both hands to crimp the tubular terminal and the cable with all their strength.

[0003] The currently published patent: CN212062731U discloses a tubular terminal block, in which a spring sheet is fixed on the inner wall of the wiring hole. When the cable is inserted into the wiring hole, the spring sheet applies pressure to the spring sheet, and the spring sheet clamps the cable under the action of the restoring force, so that the operator can directly crimp the tubular terminal block and the cable with all his strength, simplifying the crimping process and improving the crimping efficiency.

[0004] Based on the above search, it is found that the above patent has the following problems when in use: during the process of crimping the cable with the tubular terminal, the cable exerts pressure on the spring sheet when inserted into the wiring hole, so the spring sheet can clamp the cable under the action of the restoring force, thereby facilitating the operator to directly crimp the tubular terminal. Since the surface of the spring sheet is relatively smooth, the friction between the spring sheet and the cable is small. Although the spring sheet can clamp the cable, the cable is still easy to slide on the surface of the spring sheet and move out of the wiring hole. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art, and provides a tubular plug terminal with an anti-dropping function, which can solve the problem that since the surface of the spring sheet is relatively smooth and the friction between the spring sheet and the cable is relatively small, although the spring sheet can clamp the cable, the cable is still easy to slide on the surface of the spring sheet and move out of the interior of the wiring hole.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tubular plug-in terminal with an anti-drop function, comprising a wiring terminal and a wiring fixing device; a wiring hole is provided at one end of the wiring terminal away from the flat end; the wiring fixing device comprises two circular rings and barbs, the two circular rings are fixedly connected to the inside of the wiring hole, the surfaces of the two circular rings are welded with barbs, and the barbs are distributed equidistantly in a circle around the center of the circular ring on the surface of the circular ring.

[0007] Preferably, a flat plate end is welded on the surface of the terminal, and a connecting hole is opened on the surface of the flat plate end.

[0008] Preferably, the barbs on the left side of the circular ring surface are smaller than the barbs on the right side of the circular ring surface.

[0009] Preferably, a plastic sliding sleeve is slidably sleeved on the surface of the wiring terminal, and a positioning groove is provided on the inner wall of the plastic sliding sleeve.

[0010] Preferably, a positioning clamp ring is welded on the surface of the wiring terminal, and the positioning clamp ring is slidably engaged in the interior of the positioning clamp groove.

[0011] Preferably, a protective cover is fixedly connected to the surface of the plastic sliding sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The tubular connector with anti-drop function fixes the cable by two sections of barbs, so the cable can be firmly fixed and connected to the inside of the wiring hole. Compared with the spring sheet clamping the cable, the barb structure fixes the cable more stably, so it is more convenient for the operator to directly crimp the tubular terminal and the cable, simplifying the crimping process of the staff and improving the convenience of the staff in crimping the cable.

[0014] (2) The tubular connector terminal with an anti-drop function has a plastic sleeve that slides and drives the protective cover to gradually move to the left and cover the connection position between the cable and the flat end. At this time, the protective cover can be used to protect the connection position between the cable and the flat end, thereby improving the stability of the connection between the cable and the flat end and ensuring the stability of the use of the tubular connector terminal.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] See also Figure 1-4 The utility model provides a technical solution: a tubular plug-in terminal with an anti-drop function, comprising a wiring terminal 1 and a wiring fixture, a flat plate end 3 is welded on the surface of the wiring terminal 1, a connecting hole 4 is provided on the surface of the flat plate end 3, a wiring hole 2 is provided at one end of the wiring terminal 1 away from the flat plate end, and the wiring fixture comprises two circular rings 5 ​​and barbs 6, the two circular rings 5 ​​are fixedly connected to the inside of the wiring hole 2, the surfaces of the two circular rings 5 ​​are welded with barbs 6, the barbs 6 are equidistantly distributed in a circle around the center of the circular ring 5, and the barbs on the surface of the left circular ring 5 are smaller than the barbs on the surface of the right circular ring 5;

[0026] When the tubular connector with anti-drop function is in use, the staff peels off the plastic on the surface of the cable and inserts it into the wiring hole 2. The cable enters the wiring hole 2 and first passes through the right ring 5 and squeezes the barb 6 on its surface. Then the cable gradually moves to the left and passes through the left ring 5 and squeezes the barb 6 on its surface. At this time, the cable moves to the leftmost side of the terminal 1. Since the barb 6 on the left is smaller than the barb on the right, the cable opens more inside the left ring 5 than inside the right ring 5. When the cable wants to move to the right and slide out of the wiring hole 2 When the cable is inserted into the wiring hole 2, the barbs on the surfaces of the two circular rings 5 ​​fix the cable, and the leftmost end of the cable opens wider, so the cable cannot escape from the inside of the two circular rings 5, and then cannot be moved out of the wiring hole 2, and the cable is fixed by the two sections of barbs 6, so the cable can be firmly fixed and connected to the inside of the wiring hole 2. Compared with the spring sheet clamping the cable, the structure of the barb 6 fixes the cable more stably, so it is more convenient for the operator to directly crimp the tubular terminal 1 and the cable with all his strength, which simplifies the crimping process of the staff and improves the convenience of the staff in crimping the cable.

[0027] A positioning clamp ring 7 is welded on the surface of the terminal 1, and a plastic sleeve 8 is slidably sleeved on the surface of the terminal 1. A positioning groove 10 is opened on the inner wall of the plastic sleeve 8, and the positioning clamp ring 7 is slidably clamped inside the positioning groove 10. A protective cover 9 is fixedly connected to the surface of the plastic sleeve 8.

[0028] When the staff inserts the cable into the connecting hole 4 and completes the connection with the flat end 3, the staff gradually slides the plastic sleeve 8 to the left on the surface of the terminal 1, the plastic sleeve 8 slides on the surface of the terminal 1 and drives the positioning groove 10 to be clamped on the surface of the positioning clamp ring 7, and then the plastic sleeve 8 is fixedly installed on the surface of the terminal 1, the plastic sleeve 8 slides and drives the protective cover 9 to gradually move to the left and cover the connection position of the cable and the flat end 3. At this time, the protective cover 9 can be used to protect the connection position of the cable and the flat end 3, thereby improving the stability of the connection between the cable and the flat end 3 and ensuring the stability of the use of the tube-type connector.

[0029] Working principle: for the tubular connector with anti-slip function, the staff inserts the cable into the wiring hole 2, and the cable first passes through the right ring 5 and squeezes the barb 6 on its surface, and then passes through the left ring 5 and squeezes the barb 6 on its surface. When the cable wants to move to the right and slide out of the wiring hole 2, the barbs on the surfaces of the two rings 5 ​​fix the cable, and the leftmost end of the cable opens wider, so the cable cannot move out of the wiring hole 2. Compared with the spring sheet clamping the cable, the structure of the barb 6 fixes the cable more stably. The staff gradually slides the plastic sleeve 8 to the left on the surface of the wiring terminal 1 and drives the positioning slot 10 to be clamped on the surface of the positioning ring 7. The plastic sleeve 8 slides and drives the protective cover 9 to gradually move to the left and cover the connection position of the cable and the flat end 3. At this time, the connection position of the cable and the flat end 3 can be protected by the protective cover 9.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
