Description

Technical Field

[0001] This utility model relates to the field of switch terminal crimping technology, and in particular to a crimping and forming device for switch terminals. Background Technology

[0002] Switch terminal blocks are accessories used to achieve electrical connections and regulate the opening and closing of circuits. As industrial automation increases and industrial control requirements become more stringent and precise, the use of terminal blocks is gradually rising. Switch connectors are relay stations for circuit connections, connecting wire harnesses by inserting wire harness terminals into the switch connector.

[0003] The existing method of clamping the wire harness with bolts is generally to do so. However, the contact area between one end of the bolt and the wire harness is small, resulting in an unstable clamping. This method cannot effectively fix the wire harness and needs to be improved.

[0004] Therefore, this application proposes a crimping and forming apparatus for switch terminals to solve the problems in the prior art.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crimping and forming device for switch terminals.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A crimping and forming apparatus for switch terminals includes a switch body and a crimping mechanism;

[0009] Two mounting slots are provided on one side of the switch body. Each of the two mounting slots is equipped with a crimping mechanism. Two bolts are rotatably connected to the switch body. The bolts are respectively connected to the two crimping mechanisms. Wire harnesses are inserted into each of the two mounting slots. The two crimping mechanisms are respectively connected to the two wire harnesses.

[0010] The crimping mechanism includes a base, a conductive block, an arc-shaped pressure plate, a sleeve, a fixing plate, an insulating plate, and a protrusion. A base is fixedly installed in each of the two mounting slots, and a conductive block is fixedly installed on one side of each of the two bases. One end of each of the two wire harnesses abuts against the two conductive blocks. Through the design of the switch body, the crimping mechanism, and the bolts, the clamping force on the wire harness is increased, thereby achieving crimping fixation between the crimping mechanism and the wire harness, effectively ensuring the firmness of the crimping. Furthermore, after the wire harness is crimped, it effectively prevents external contact with the crimping mechanism and the wire harness, avoiding accidents caused by contact and greatly improving practicality and safety.

[0011] Preferably, each of the two mounting slots is slidably connected to an arc-shaped pressure plate, and a sleeve is fixedly connected to one side of each of the two arc-shaped pressure plates. One end of each of the two bolts is threadedly connected to the two sleeves respectively. Through the threaded transmission between the two bolts and the two sleeves respectively, the two arc-shaped pressure plates can be moved and adjusted.

[0012] Preferably, one end of the sleeve is slidably connected to the switch body, which is a detachable connection.

[0013] Preferably, the arc-shaped pressure plate is adapted to the conductive block and abuts against the wire harness, and is used to clamp and fix one side of the wire harness.

[0014] Preferably, a fixing plate is fixedly connected to one side of the arc-shaped pressure plate, and an insulating plate is fixedly connected to one end of the fixing plate. One end of the insulating plate abuts against the wire harness. After the wire harness is crimped, it can effectively prevent external contact with the crimping mechanism and the wire harness, and avoid accidents caused by contact.

[0015] Preferably, a protrusion is fixedly connected to one side of the base, and the protrusion is in contact with the wire harness, which facilitates pressing one end of the wire harness into an S-shape, thereby increasing the friction between the wire harness and the arc-shaped pressure plate and the conductive block.

[0016] Preferably, one end of the insulating plate has a first groove, and one side of the base has a second groove, which corresponds to the first groove, so as to facilitate further clamping and fixing of the wire harness and improve its firmness.

[0017] Preferably, the switch body has a sliding groove, the sleeve slides in the sliding groove, and the switch body has two through holes, which correspond to the two mounting grooves respectively. The two through holes facilitate the use of a test pen to test the wire harness and the switch body in the two mounting grooves.

[0019] This utility model discloses a crimping and forming device for switch terminals. Through the design of the switch body, crimping mechanism, and bolts, the clamping force on the wire harness can be increased, thereby achieving crimping and fixing between the crimping mechanism and the wire harness, effectively ensuring the firmness of the crimping.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a crimping and forming device for switch terminals, referring to... Figures 1-4 A crimping and forming apparatus for switch terminals includes a switch body 1 and a crimping mechanism 2;

[0028] Two mounting slots are provided on one side of the switch body 1. Each mounting slot is equipped with a crimping mechanism 2. Two bolts 3 are rotatably connected to the switch body 1. An insulating bearing is fixedly sleeved on each of the two bolts 3. The outer walls of the two insulating bearings are fixedly connected to the switch body 1. The filter bolts 3 are respectively connected to the two crimping mechanisms 2. Wire harnesses 4 are inserted into each of the two mounting slots. The two crimping mechanisms 2 are respectively connected to the two wire harnesses 4.

[0029] The crimping mechanism 2 includes a base 21, a conductive block 22, an arc-shaped pressure plate 23, a sleeve 24, a fixing plate 25, an insulating plate 26, and a protrusion 27. A base 21 is fixedly installed in each of the two mounting slots, and a conductive block 22 is fixedly installed on one side of each base 21. One end of each of the two wire harnesses 4 abuts against the two conductive blocks 22. Through the design of the switch body 1, the crimping mechanism 2, and the bolts 3, the clamping force on the wire harnesses 4 can be increased, thereby achieving crimping fixation between the crimping mechanism 2 and the wire harnesses 4, effectively ensuring the firmness of the crimping. Moreover, after the wire harnesses 4 are crimped, it can effectively prevent external contact with the crimping mechanism 2 and the wire harnesses 4, avoiding accidents caused by contact, and greatly improving practicality and safety.

[0030] In this embodiment, two arc-shaped pressure plates 23 are slidably connected in each of the two mounting slots. A sleeve 24 is fixedly connected to one side of each of the two arc-shaped pressure plates 23. One end of each of the two bolts 3 is threadedly connected to the two sleeves 24. Through the threaded transmission between the two bolts 3 and the two sleeves 24, the two arc-shaped pressure plates 23 can be moved and adjusted.

[0031] In this embodiment, one end of the sleeve 24 is slidably connected to the switch body 1, which is a detachable connection.

[0032] In this embodiment, the arc-shaped pressure plate 23 is adapted to the conductive block 22 and abuts against the wire harness 4, and is used to clamp and fix one side of the wire harness 4.

[0033] In this embodiment, a fixing plate 25 is fixedly connected to one side of the arc-shaped pressure plate 23, and an insulating plate 26 is fixedly connected to one end of the fixing plate 25. One end of the insulating plate 26 abuts against the wire harness 4. After the wire harness 4 is crimped, it can effectively prevent external contact with the crimping mechanism 2 and the wire harness 4, and avoid accidents caused by contact.

[0034] In this embodiment, a protrusion 27 is fixedly connected to one side of the base 21. The protrusion 27 contacts and connects with the wire harness 4, making it easy to press one end of the wire harness 4 into an S-shape (see attached figure). Figure 3 and Figure 4 This increases the friction between the wire harness 4 and the arc-shaped pressure plate 23 and the conductive block 22. The protrusion 27, the base 21, the arc-shaped pressure plate 23, the sleeve 24 and the fixing plate 25 are all made of insulating material, and appropriate insulating material can be selected according to the actual situation.

[0035] In this embodiment, a groove 5 is provided at one end of the insulating plate 26, and a groove 6 is provided on one side of the base 21. The groove 6 corresponds to the groove 5, which facilitates further clamping and fixing of the wire harness 4 and improves its firmness.

[0036] In this embodiment, a sliding groove is provided on the switch body 1, and the sleeve 24 slides in the sliding groove. Two through holes 7 are provided on the switch body 1, and the two through holes 7 correspond to the two mounting grooves. The two through holes 7 facilitate the use of a test pen to test the wire harness 4 and the switch body 1 in the two mounting grooves.

[0037] Working principle: In use, first remove the outer sheath of one end of the wire harness 4 and insert it into the mounting groove 1 on the switch body 1, so that it is positioned between the arc-shaped pressure plate 23 and the base 21. Then, turn the bolt 3 with a screwdriver. At the same time, the bolt 3 and the sleeve 24 are threaded, so that the arc-shaped pressure plate 23 slides down in the mounting groove 1 and acts with the conductive block 22 and the base 21, thereby achieving the effect of clamping and fixing the wire harness 4. In this process, the friction between the arc-shaped pressure plate 23, the conductive block 22 and the protrusion 27 increases, thereby preventing the wire harness 4 from moving or falling off.

[0038] During the sliding process of the arc-shaped pressure plate 23, the insulating plate 26 is driven to slide on the switch body 1 through the transmission of the fixed plate 25. Through the cooperation between the first groove 5 and the second groove 6, the wire harness 4 can be further clamped and fixed. At the same time, the insulating plate 26 can seal the first mounting groove, which has a protective effect and improves safety.

[0039] Conversely, this can achieve the effect of unscrewing the wire harness 4, and then pulling it out of the mounting slot 1, thereby achieving the effect of disassembling the wire harness 4.

[0040] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the wire harness 4 be clamped and fixed in multiple stages, but accidental contact can also be prevented, greatly improving safety. Moreover, the structure is simple and the practicality is higher.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
