Description

Technical Field

[0001] This application relates to the technical field of electrical connector part processing, and particularly relates to an anti-misoperation structure and a crimping die. Background Art

[0002] In the fields of electronics, electrical engineering, communication, etc., a terminal is a basic component for connecting circuits, and its quality and reliability directly affect the normal operation and maintenance of equipment. Currently, traditional terminals are usually bent using a crimping die. First, the operator places the terminal to be bent on the workbench, and then the crimping die bends the terminal.

[0003] However, before placing the terminal to be bent on the workbench, it is necessary to confirm whether the terminal to be bent is correct. Refer to Figure 1 and Figure 2 , Figure 1 wherein 70 is the correct terminal, Figure 2 80 is a similar terminal. The correct terminal 70 has an opening 71 at a specified position, while the similar terminal 80 has no opening or the opening position is deviated. Currently, only the operator can visually identify the correct terminal 70 and the similar terminal 80 by eyes. When the operator mistakenly takes the similar terminal 80 for production, it will cause serious quality accidents. Therefore, it is particularly important to identify the correct terminal 70 and the similar terminal 80 before bending the terminal. Summary of the Utility Model

[0004] This application provides an anti-misoperation structure and a crimping die to solve the technical problem of quality accidents caused by mistakenly taking similar terminals for production.

[0008] A first detection component, slidably passing through the fixed seat along the first direction;

[0009] An adjusting component, mounted on the base along the first direction, and the adjusting component is disposed opposite to the first detection component;

[0010] Wherein, the first detection component has a detection end and a contact end. The detection end is disposed on the side close to the receiving cavity, and the contact end is disposed on the side close to the adjusting component. The contact end is configured to contact the adjusting component as the moving component moves, and make the detection end pass through the opening of the correct terminal or contact the similar terminal under the action of the adjusting component, so as to realize the identification of the terminal.

[0011] As one of the optional embodiments of this solution, it further includes a second detection member. An installation plate is provided on the base, and the second detection member passes through the installation plate. The second detection member is arranged towards the fixed seat in the first direction. The moving component has a stroke end point, and the second detection member has an effective triggering stroke. When the moving component moves to the stroke end point, the second detection member reaches the effective triggering stroke to identify whether the moving component and the terminal move in place.

[0012] As one of the optional embodiments of this solution, the adjusting member passes through the installation plate. The adjusting member has a pushing surface arranged towards the first detection member. The installation plate has an installation surface arranged towards the first detection member, and the distance between the pushing surface and the installation surface is adjustable.

[0013] As one of the optional embodiments of this solution, the moving component further includes a sliding plate. A sliding groove is formed on the base, and the sliding plate is slidably arranged in the sliding groove. A limiting strip is provided on the sliding plate, and a limiting groove is formed on the inner wall of the sliding groove. The limiting strip is slidably arranged in the limiting groove in the first direction, and the fixed seat is installed on the sliding plate.

[0014] As one of the optional embodiments of this solution, the moving component further includes a positioning member. The positioning member is rotatably connected to the sliding plate, and a positioning groove is formed on the base. The positioning groove is configured to allow the positioning member to be inserted when the sliding plate moves to the stroke end point.

[0015] As one of the optional embodiments of this solution, the fixed seat is slidably installed on the sliding plate in the first direction. An adjusting groove is formed on the sliding plate, and the adjusting groove is configured to allow the first positioning member to be inserted to position the fixed seat.

[0016] As one of the optional embodiments of this solution, a support member is provided on the side of the fixed seat away from the contact end. The support member is arranged on the sliding plate, and the support member has a support surface that contacts at least a part of the terminal.

[0017] As one of the optional embodiments of this solution, the support member is slidably installed on the sliding plate in the first direction, and a second positioning member for limiting the support member is provided on the sliding plate.

[0018] As one of the optional embodiments of this solution, the moving component further includes an adjusting block. An adjusting cavity is formed in the fixed seat, and the adjusting block is slidably installed in the adjusting cavity in the first direction.

[0019] On the other hand, the present application further provides a crimping die, including any one of the above anti-misoperation structures.

[0020] One of the above technical solutions has the following advantages or beneficial effects:

[0021] Before the terminal is crimped, the terminal is first placed in the accommodating cavity, and then the moving component carrying the terminal is pushed toward one side of the mounting plate along the first direction. With the movement of the moving component, the first detection member moves toward the side close to the adjusting member. After the adjusting member contacts the first detection member, the moving component continues to be pushed. The adjusting member pushes the contact end of the first detection member under the reaction force, so that the first detection member moves in the opposite direction along the first direction. When the terminal in the accommodating cavity is the correct terminal, the detection end of the first detection member passes through the opening of the correct terminal, and the first detection member collects similar terminal signals. When the terminal in the accommodating cavity is a similar terminal, the detection end of the first detection member conflicts with the similar terminal, and the detection end of the first detection member collects similar terminal signals, thereby realizing the identification and distinction between the correct terminal and the similar terminal. By setting an error-proofing structure, similar terminals can be identified and excluded before the terminals are crimped, and the crimping mold can be prevented from crimping similar terminals as much as possible, thereby avoiding crimping quality accidents.

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0034] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after without special explanation.

[0035] In the fields of electronics, electrical, communication, etc., the wiring terminal is a basic component for connecting circuits, and its quality and reliability directly affect the normal operation and maintenance of equipment. At present, traditional wiring terminals usually use a crimping die for bending. First, the terminal to be bent is placed on the workbench by the staff, and then the terminal is bent by the crimping die.

[0036] However, before placing the terminal to be bent on the workbench for crimping, it is necessary to confirm whether the terminal to be bent is correct. Refer to Figure 1 and Figure 2 , Figure 1 is the correct terminal 70, Figure 2For similar terminals 80, the correct terminal 70 is provided with an opening 71 at a specified position, while the similar terminal 80 is not provided with an opening or there is a deviation in the opening position. Currently, only the correct terminal 70 and the similar terminal 80 can be identified by the naked eye of the staff. When the staff mistakenly takes the similar terminal 80 for production, it will cause serious quality accidents. Therefore, it is particularly important to identify the correct terminal 70 and the similar terminal 80 before the terminal is bent.

[0037] Therefore, the present application provides an anti-mistake structure and a crimping die. The anti-mistake structure provided by the present application is arranged in the crimping die, and the anti-mistake structure can identify the correct terminal 70 and the similar terminal 80 before terminal crimping. It can be understood that the anti-mistake structure can also identify other similar products with an opening 71, not limited to identifying the correct terminal 70 and the similar terminal 80. For example, the anti-mistake structure can also identify and distinguish sheet metal parts with an opening 71 and without an opening 71, etc., which is not limited herein. The anti-mistake structure and the crimping die provided by the present application will be described below.

[0038] Refer to Figure 3 and Figure 4 The anti-mistake structure provided by the present application includes a base 10 and a moving component 20. The moving component 20 is slidably mounted on the base 10 along a first direction ( Figure 3 the X direction in Figure 5 and Figure 6 ). The moving component 20 includes a fixed seat 210. An accommodation cavity 211 is formed in the fixed seat 210 for at least part of the terminal to be inserted. The anti-mistake structure further includes a first detection component 30 and an adjustment component 40. The first detection component 30 is slidably inserted through the fixed seat 210 along the first direction X. An installation plate 11 is fixed on the base 10. The adjustment component 40 is inserted through the installation plate 11 along the first direction X. The adjustment component 40 is disposed opposite to the first detection component 30, that is, the axes of the adjustment component 40 and the first detection component 30 are parallel or coincident. Refer to

[0039] Before terminal crimping, first place the terminal in the receiving cavity 211, and then push the moving component 20 carrying the terminal along the first direction X towards the mounting plate 11. As the moving component 20 moves, the first detecting member 30 moves towards the adjusting member 40. After the adjusting member 40 contacts the first detecting member 30, continue to push the moving component 20. Under the reaction force, the adjusting member 40 pushes the contact end 32 of the first detecting member 30, causing the first detecting member 30 to move in the reverse direction of the first direction X. When the terminal in the receiving cavity 211 is the correct terminal 70, the detecting end 31 of the first detecting member 30 passes through the opening 71 of the correct terminal 70. In some embodiments, a detecting groove 212 may be formed on the fixing base 210. The detecting groove 212 communicates with the correct terminal 70 and can accommodate the detecting end 31 of the first detecting member 30. That is to say, when the first detecting member 30 can pass through the opening 71 and enter the detecting groove 212, the first detecting member 30 collects the signal of the similar terminal 80. When the terminal in the receiving cavity 211 is a similar terminal, the detecting end 31 of the first detecting member 30 abuts against the similar terminal 80, and the detecting end 31 of the first detecting member 30 collects the signal of the similar terminal 80. In this way, the correct terminal 70 and the similar terminal 80 can be identified and distinguished. By setting the anti-mistake structure, the similar terminal 80 can be identified and excluded before terminal crimping, and the crimping die is prevented from crimping the similar terminal 80 as much as possible, thereby avoiding crimping quality accidents.

[0040] It is easy to understand that in this embodiment, the first detecting member 30 is a probe, and a spring (not shown in the figure) is arranged inside the probe. When the contact end 32 of the first detecting member 30 is separated from the adjusting member 40, the detecting end 31 of the probe can be reset under the action of the spring, so that the detecting end 31 moves out of the detecting groove 212, facilitating the identification and detection of the next terminal. The specific structure of the probe is prior art and will not be elaborated here.

[0041] Refer to Figure 7 , in some embodiments, the adjusting member 40 has a pushing surface 41 facing the first detecting member 30, the mounting plate 11 has a mounting surface 12 facing the first detecting member 30, the pushing surface 41 is closer to the first detecting member 30 than the mounting surface 12, and the distance between the pushing surface 41 and the mounting surface 12 is adjustable.

[0042] Therefore, by setting the distance between the pushing surface 41 and the mounting surface 12 to be adjustable, before detecting and identifying terminals of different thicknesses and specifications, the position of the adjusting member 40 can be adjusted to make the anti-mistake structure applicable to terminals of different specifications, so as to improve the applicability of the anti-mistake structure.

[0043] It can be understood that in this embodiment, the adjusting member 40 is specifically a bolt, which is threadedly connected to the mounting plate 11. A nut is threadedly connected to the bolt. By rotating the bolt, the distance between the pushing surface 41 and the mounting surface 12 can be adjusted, and the position is locked and fixed by the nut. The structure is simple and easy to operate.

[0044] Further, continue to refer to Figure 7 , the anti-misoperation structure provided by the present application further includes a second detection member 50. The second detection member 50 is inserted through the mounting plate 11 and is arranged towards the fixed seat 210 along the first direction X. The moving assembly 20 has a stroke end point, and the second detection member 50 has an effective triggering stroke. When the moving assembly 20 moves to the stroke end point, the second detection member 50 reaches the effective triggering stroke. At this time, the second detection member 50 detects a in-place signal to identify whether the moving assembly 20 and the terminals on the moving assembly 20 have moved in place. It can be understood that when the moving assembly 20 does not move to the stroke end point, the second detection member 50 cannot reach the effective triggering stroke. If the crimping is performed when the moving assembly 20 is not in place, it will cause inaccurate crimping positions, affect the crimping effect, and even cause crimping quality accidents.

[0045] Place the terminal in the accommodating cavity 211, and push the moving assembly 20 towards the mounting plate 11. When the terminal is the correct terminal 70, the detection end 31 of the first detection member 30 passes through the opening 71 of the correct terminal 70 and enters the detection groove 212. The first detection member 30 reaches the effective recognition stroke, and at this time, the signal of the correct terminal 70 is recognized; at the same time, the moving assembly 20 reaches the stroke end point, and the second detection member 50 abuts against the fixed seat 210. The second detection member 50 reaches the effective triggering stroke, and at this time, the in-place signal of the correct terminal 70 is recognized. After the first detection member 30 reaches the effective recognition stroke and the second detection member 50 reaches the effective triggering stroke, the crimping die will start to crimp the correct terminal 70, so as to avoid crimping the similar terminals 80 and the terminals that are not in place, which helps to ensure the crimping quality.

[0046] It is not difficult to understand that when the terminal is the similar terminal 80, the detection end 31 of the first detection member 30 abuts against the similar terminal 80, and the first detection member 30 cannot reach the effective recognition stroke. At the same time, the moving assembly 20 also cannot reach the stroke end point, and the second detection member 50 also cannot reach the effective triggering stroke. At this time, the crimping die will not start, so as to avoid crimping the similar terminals 80 and the terminals that are not in place, which helps to ensure the crimping quality.

[0047] Refer to Figure 7 and Figure 8, in some embodiments, the moving component 20 further includes a sliding plate 220 and a positioning member 230. A sliding groove 110 is formed on the base 10. The sliding plate 220 is slidably disposed in the sliding groove 110. A limiting strip 221 is fixed on the sliding plate 220. The limiting strip 221 extends along the first direction X. A limiting groove 111 is formed on the inner wall of the sliding groove 110. The limiting groove 111 is formed along the first direction X and is communicated with the sliding groove 110. The limiting strip 221 is slidably disposed in the limiting groove 111 along the first direction X. A positioning plate 270 is fixed on the sliding plate 220. The positioning member 230 is rotatably connected to the positioning plate 270. A positioning groove 120 is formed on the base 10. The positioning groove 120 is configured to receive the positioning member 230 when the sliding plate 220 moves to the end of the stroke.

[0048] Specifically, referring to Figure 7 , the rotation axis of the positioning member 230 is arranged along the first direction X. The positioning member 230 includes a handle portion 231 and a positioning portion 232. The handle portion 231 and the positioning portion 232 are integrally formed. Both the positioning portion 232 and the positioning groove 120 extend along the second direction ( Figure 7 the Y direction in

[0049] In some embodiments, referring to Figure 7 and Figure 8 , a support member 60 is disposed on the side of the fixed seat 210 away from the mounting plate 11. The support member 60 is mounted on the sliding plate 220 and is disposed in contact with the fixed seat 210. One side of the support member 60 facing away from the sliding plate 220 is provided with a support surface, and the support surface is in contact with at least a part of the terminal. The support member 60 is used to support the terminal to ensure a good crimping effect. It can be understood that the support member 60 is specifically a support block in this embodiment, and may also be in the shape of a plate or a strip in other embodiments, which is not limited herein.

[0050] In some embodiments, referring to Figure 7 and Figure 8, the size of the accommodating cavity 211 is adapted to the size of the terminal, that is, the accommodating cavity 211 can just accommodate one terminal, so as to avoid the terminal from being offset during the crimping process as much as possible. Furthermore, in the present embodiment, an adjustment cavity 213 is provided in the fixed seat 210, and the movable assembly 20 also includes an adjustment block 240, which is slidably installed in the adjustment cavity 213 along the first direction X, and the adjustment block 240 divides the adjustment cavity 213 into two chambers, wherein the chamber close to the terminal side is the accommodating cavity 211. The terminal is clamped by the fixed seat 210 and the adjustment block 240 to realize the positioning of the terminal in the accommodating cavity 211, and the terminal is avoided from being offset during the crimping process as much as possible to ensure the crimping effect of the terminal.

[0051] A first fixing hole 260 is provided on the side of the fixing seat 210 away from the support member 60, and a second fixing hole (not shown in the figure) is provided on the adjusting block 240. The first fixing hole 260 and the second fixing hole are coaxially arranged, and the first fixing hole 260 and the second fixing hole are configured to allow a fixing member (not shown in the figure) to pass through. In this embodiment, the fixing member is specifically a bolt, and the fixing member is simultaneously inserted into the first fixing hole 260 and the second fixing hole. The fixing member is threadedly connected to the first fixing hole 260. By rotating the fixing member, the fixing member can drive the adjusting block 240 to move in the adjusting cavity 213 along the first direction X to adjust the size of the accommodating cavity 211, so that the size of the accommodating cavity 211 can be adjusted according to terminals of different thicknesses and sizes, so that the error-proofing structure is applicable to terminals of various sizes, thereby improving the applicability of the crimping mold. It is not difficult to understand that in other embodiments, the fixing member can be a screw rod or a stud, etc., which is not limited here.

[0052] In some embodiments, see Figure 6 The sliding plate 220 is provided with an adjustment groove 250, which is specifically a waist-shaped groove provided along the first direction X. The adjustment groove 250 penetrates the base 10 along the thickness direction of the base 10, and the adjustment groove 250 is configured for the insertion of a first positioning member (not shown in the figure). The fixed seat 210 is provided with a positioning hole (not shown in the figure) on the side facing the base 10, and the positioning hole is also used for the insertion of the first positioning member. The first positioning member is specifically a bolt in this embodiment. In other embodiments, the first positioning member may be a stud or a latch, etc., which is not limited here. By having the first positioning member pass through the adjustment groove 250 and the positioning hole in sequence, the fixed seat 210 can be positioned so as to adjust the position of the fixed seat 210.

[0053] Similarly, the support member 60 is slidably mounted on the sliding plate 220 along the first direction X, and a second retaining member (not shown in the figure) for limiting the position of the support member 60 is provided on the sliding plate 220. The second retaining member passes through the adjustment slot 250 and contacts the support member 60 to achieve the positioning of the support member 60. The second retaining member is specifically a bolt in this embodiment. In other embodiments, the second retaining member can be a stud or a latch, etc., which is not limited here. By providing the second retaining member, after adjusting the position of the support member 60, it is convenient to position the support member 60 to ensure the stability of the terminal during crimping.

[0054] An embodiment of the present application also provides a crimping die, including the above error-proofing structure. After the error-proofing structure identifies the correct terminal 70 and the correct terminal 70 moves to the correct position, the crimping die will start to crimp the terminal. Therefore, the crimping die provided by the present application can avoid the problem of mistakenly producing similar terminals 80, can avoid production quality accidents as much as possible, and can also avoid the problem of crimping the terminal before it moves into place, thereby ensuring the crimping effect and crimping quality of the terminal.

[0055] The above description is only a partial implementation method of the embodiments of the present application and does not constitute any form of limitation on the application. The protection scope of the embodiments of the present application is not limited thereto.
