[0003] Power batteries include various connectors, and the connectors need to be pulled out during use or maintenance, so how to conveniently pull out the connectors is an urgent problem to be solved. SUMMARY

[0004] In view of the above problems, the present application provides a pulling tool for a connector to improve the convenience of pulling out the connector.

[0005] The present application provides a pulling tool for a connector for pulling out the connector from a base body, comprising a base, a clamping structure and an operating handle. The clamping structure is arranged on the base and comprises two clamping arms arranged at intervals in a first direction. A clamping space for clamping the connector is defined between the two clamping arms. The operating handle is rotatably connected to the base, and the rotation axis of the operating handle is configured to extend along the first direction. The first end of the operating handle is connected to the clamping structure, and the second end of the operating handle is configured to move towards the base under the action of an external force to drive the operating handle to rotate so that the first end of the operating handle moves away from the base to pull out the connector.

[0006] The technical scheme of the present application provides a pulling tool that first clamps and fixes the connector by using the clamping structure, and then applies an external force to the second end of the operating handle to move the second end of the operating handle towards the base and make the operating handle rotate around the rotation axis. This makes the first end of the operating handle move away from the base and realize the pulling out of the connector. The use of the pulling tool of the present application to pull out the connector improves the convenience of pulling out the connector.

[0007] In some embodiments, the pulling tool further comprises a guide structure for guiding the movement of the second end of the operating handle to move the second end of the operating handle in a second direction perpendicular to the first direction.

[0008] The technical scheme of the present application provides a guide structure to guide the movement of the second end of the operating handle, so that the movement direction of the second end of the operating handle is limited to the second direction, and the movement path of the connector when pulled out is perpendicular to the surface of the base body, thereby avoiding damage to the electrical connection between the connector and the base body.

[0009] In some embodiments, the guide structure comprises a connecting column arranged on the operation handle and a guide long hole arranged on the base, the length direction of the guide long hole extends along the second direction, and the connecting column is arranged in the guide long hole. The drawing tool of the embodiments of the present application draws the connector by arranging the guide long hole on the base, so that when the operation handle moves, the movement of the connecting column connected with the operation handle is limited by the guide long hole, that is, the connecting column can only move along the extension direction of the guide long hole, that is, along the second direction, and then the first end of the operation handle connected with the connecting column and the clamping structure connected with the first end of the operation handle move along the second direction, and then the connector clamped by the clamping structure also moves along the second direction relative to the base to be drawn out.

[0010] In some embodiments, the base comprises a bottom plate and a side plate arranged on at least one side of the bottom plate, the operation handle is arranged on one side of the bottom plate and is rotatably connected to the side plate, and the guide long hole is arranged on the side plate.

[0011] In some embodiments, the guide structure further comprises a guide groove arranged on the side plate and extending along the second direction, and the clamping structure comprises a clamping seat and a clamping arm arranged on the clamping seat, and the clamping seat is configured to move in the guide groove. The drawing tool of the embodiments of the present application limits the movement direction of the clamping seat by arranging the guide groove extending along the second direction on the side plate, so that the movement path of the connector when being drawn out is perpendicular to the surface of the base, and damage to the electrical connection between the connector and the base is avoided.

[0012] In some embodiments, the clamping structure comprises a clamping seat and a clamping arm arranged on the clamping seat, the clamping seat has a connecting groove, the first end of the operation handle is arranged in the connecting groove, the first end of the operation handle is provided with a through connecting hole, and the connecting column is arranged in the connecting hole and connected with the connecting groove.

[0013] In some embodiments, the clamping seat has a recess, the clamping arm has a protrusion, and the protrusion and the recess are matched. By arranging the protrusion on the clamping arm and the recess on the clamping seat, the position of the clamping arm can be accurately positioned by matching the protrusion and the recess when the clamping arm is connected.

[0014] In some embodiments, the drawing tool further comprises a reset spring arranged between the operation handle and the base.

[0015] In some embodiments, the clamping structure is configured to move along a third direction toward the connector on the surface of the substrate so that the connector gradually enters the clamping space. The clamping structure also includes an unlocking part configured to press a latching structure on the connector inward during the movement of the clamping structure along the third direction toward the connector, thereby disengaging the latching structure.

[0016] In some embodiments, the clamping structure is configured to move along a third direction on the surface of the substrate toward the connector so that the connector gradually enters the clamping space. The clamping arm has a clamping surface on the side near the connector, and the clamping surface is configured to be inclined relative to the third direction so that as the clamping structure moves toward the connector, the distance between the clamping surface and the connector gradually decreases, thereby causing the snap-fit ​​structure on the connector to disengage.

[0017] In some embodiments, the surfaces of the base, clamping structure, and operating handle are provided with an insulating protective layer. This insulating protective layer effectively prevents connector damage caused by electric arcing during connector removal or disconnection.

[0040] refer to Figure 1 When the connector 100 inside the battery system is connected to the base 200, the bottom end of the connector 100 is electrically connected to the base 200. Here, the bottom end refers to the end of the connector 100 that is closest to the base 200. Figure 1 The diagram shown is a top view of the connector 100 connected to the base 200. The connector 100 and the base 200 are electrically connected. To improve the reliability of this electrical connection, as... Figure 1 As shown, the connector 100 also has a snap-fit ​​structure on its side that engages with a snap-fit ​​hole (not shown) on the base 200. Therefore, when disassembling and repairing the connector 100, it is necessary to first press the snap-fit ​​structure inward by hand to disengage it from the snap-fit ​​hole, and then pull the connector 100 outward.

[0041] As can be seen from the above pulling process, manually pulling out connector 100 requires pressing the latching structure inwards from both sides to disengage it from the locking holes. Then, while maintaining the pressing position, the connector needs to be moved away from the base 200 to pull it out. This pulling process is very laborious and inefficient. Moreover, the ribbon cable on the connector 100 is also prone to damage during the pulling process.

[0042] To address the above issues, this application provides a connector puller tool that uses a clamping structure to clamp the connector 100 from both sides to secure it. Then, the connector 100 is pulled out by pressing the operating handle. Using this puller tool to pull out the connector is effortless and thus improves the ease of connector removal.

[0043] The following is for reference. Figures 1 to 3 The structure and usage of the connector puller of some embodiments of this application will be described in detail.

[0044] refer to Figure 1 The connector puller provided in this application embodiment is used to pull the connector 100 out of the base 200.

[0045] Before describing the structure of the pulling tool of this application in detail, the direction is defined first. Figure 1 The diagram shows a top view of the connector 100 connected to the base 200. In this embodiment, the pulling tool needs to clamp the connector 100 from both sides when pulling it out. Specifically, the connector 100 is clamped and fixed in place on both sides in the first direction X, and then pulled out. This is achieved by moving the connector 100 away from the base 200, i.e., away from the plane of the paper. During pull-out, the connector 100 moves away from the base 200 in the second direction Y, which is perpendicular to both the plane of the paper and the first direction X. Before clamping the connector 100 from both sides, it needs to move along the surface of the base 200 to gradually approach the connector 100, allowing the connector 100 to enter the clamping space for clamping. The direction of movement of the pulling tool along the surface of the base 200 to gradually approach the connector 100 is the third direction Z.

[0046] refer to Figure 2 and Figure 3The connector pulling tool provided in some embodiments of this application includes a base 1, an operating handle 2, and a clamping structure 3. The clamping structure 3 is disposed on the base 1 and includes two clamping arms 32 spaced apart in a first direction X. A clamping space for clamping the connector 100 is defined between the two clamping arms 32. The operating handle 2 is rotatably connected to the base 1, and the pivot of the operating handle 2 is configured to extend along the first direction X. A first end of the operating handle 2 is connected to the clamping structure 3, and a second end of the operating handle 2 is configured to move towards the base 1 under the action of an external force, thereby driving the operating handle 2 to rotate and causing the first end of the operating handle 2 to move away from the base 1 to pull out the connector.

[0047] like Figure 2 and Figure 3 As shown, base 1 is the seat of the pulling tool, and it is a structure that integrates and connects other components. These other components are basically connected to base 1. Figure 2 In the specific embodiment shown, the base 1 has a groove-shaped structure and includes a base plate 11 and two side plates 12 disposed opposite to each other on both sides of the base plate 11. The opposite sides of the base plate 11 are open.

[0048] The clamping structure 3 is connected to the base 1 near its lower end. The clamping structure 3 includes two clamping arms 32 arranged opposite each other in the first direction X. An open clamping space is formed between the two clamping arms 32. (Reference) Figure 1 Thus, as the tool moves along the surface of the base 200 towards the connector 100, the connector 100 gradually enters the clamping space and is eventually clamped and fixed by the two clamping arms 32. The two clamping arms 32 are mounted on a clamping seat 31, which is connected to the base 1. In some embodiments, the relative distance between the two clamping arms 32 is fixed. In other embodiments, the relative distance between the two clamping arms 32 is adjustable to allow the puller to be used with connectors of different sizes.

[0049] like Figure 3 As shown, the operating handle 2 is disposed within the groove-shaped cavity of the base 1. The operating handle 2 has a first pivot hole 21 extending along the first direction X, and the side plate 12 of the base 1 also has a second pivot hole 121 extending along the first direction X. The first pivot hole 21 and the second pivot hole 121 are coaxially arranged. The rotating shaft 5 passes through the first pivot hole 21 and the second pivot hole 121 to allow the operating handle 2 to rotate about the pivot extending along the first direction X.

[0050] like Figure 2As shown, the lower end of the operating handle 2 is provided with a connection hole 22, and the connecting post 6 passes through the connection hole 22 to connect with the clamping seat 31 of the clamping structure 3. Thus, when the upper end of the operating handle 2 is pressed towards the base 1, the operating handle 2 will rotate clockwise around the rotation axis 5, which in turn causes the lower end of the operating handle 2 to rotate clockwise as well, thereby driving the clamping structure 3 to move away from the base 1 and pull out the connector.

[0051] The pull tool provided in this application first uses the clamping structure 3 to clamp and fix the connector. Then, by applying external force to the second end of the operating handle 2, the second end of the operating handle 2 moves towards the base 1, thereby causing the operating handle 2 to rotate around the pivot. This causes the first end of the operating handle 2 to move away from the base 1, thereby pulling out the connector 100. Using the pull tool of this application to pull out the connector improves the convenience of pulling out the connector.

[0052] When the first end of the operating handle 2 is pressed to rotate the operating handle 2 around the pivot, the second end of the operating handle 2 will also rotate at the same time. In order to guide the rotation of the second end of the operating handle 2 as a linear movement along the second direction Y, in some embodiments, the pulling tool further includes a guide structure for guiding the movement of the second end of the operating handle 2 so that the second end of the operating handle 2 moves along the second direction Y, which is perpendicular to the first direction X.

[0053] The technical solution of this application embodiment guides the movement of the second end of the operating handle 2 by setting a guide structure, so that the movement direction of the second end of the operating handle 2 is limited to the second direction Y, thereby making the movement path of the connector perpendicular to the surface of the base when it is pulled out, thus avoiding damage to the electrical connection between the connector and the base.

[0054] refer to Figure 2 and Figure 3 In some embodiments, the guide structure includes a connecting post 6 disposed on the operating handle 2 and a guide elongated hole 122 disposed on the base 1. The guide elongated hole 122 extends along the second direction Y. The connecting post 6 passes through the guide elongated hole 122.

[0055] The pulling fixture of this application embodiment provides a guide elongated hole 122 on the base 1. When the operating handle 2 moves, the movement of the connecting post 6 is limited by the guide elongated hole 122. That is, the connecting post 6 can only move along the extension direction of the guide elongated hole 122, that is, along the second direction Y. This causes the first end of the operating handle 2 connected to the connecting post 6 and the clamping structure 3 connected to the first end of the operating handle 2 to move along the second direction Y. As a result, the connector clamped by the clamping structure 3 also moves relative to the base body along the second direction Y, thereby achieving the pulling out.

[0056] In some embodiments, the base 1 includes a base plate 11 and a side plate 12 disposed on at least one side of the base plate 11. An operating handle 2 is spaced apart on one side of the base plate 11 and rotatably connected to the side plate 12. A guide hole 122 is disposed on the side plate 12.

[0057] like Figure 2 As shown, the base 1 has a groove-shaped structure and includes a base plate 11 and side plates 12 disposed on opposite sides of the base plate 11. The operating handle 2 is thus disposed within the groove-shaped cavity of the groove-shaped structure and rotatably connected to the side plate 12. Figure 3 As shown, the upper end of the side plate 12 is provided with a second pivot hole 121 for passing through the rotating shaft 5 so that the operating handle 2 can rotate around the rotating shaft 5. The lower end of the side plate 12 is provided with a guide elongated hole 122 so that the connecting post 6 connected to the lower end of the operating handle 2 passes through the guide elongated hole 122. By providing side plates 12 on opposite sides of the base plate 11, the rotation of the operating handle 2 is made more stable.

[0058] In other embodiments not shown in the accompanying drawings, the base 1 may also have only one side plate.

[0059] The base 1 of this application embodiment includes a base plate 11 and a side plate 12 disposed on at least one side of the base plate 11, so that the operating handle 2 can be rotatably connected to the side plate 12, making the structure of the entire drawing fixture compact and simple.

[0060] To further improve the reliability of connector removal, in some embodiments, reference is made to... Figure 3 The guide structure also includes a guide groove 123 disposed on the side plate 12 and extending along the second direction Y. The clamping structure 3 includes a clamping seat 31. A clamping arm 32 is disposed on the clamping seat 31, and the clamping seat 31 is configured to move within the guide groove 123.

[0061] like Figure 3 As shown, the inner surface of the side plate 12 is provided with a guide groove 123 extending along the second direction Y. The clamping seat 31 includes a lower clamping seat 311 and an upper clamping seat 312. The upper clamping seat 312 is connected to the upper side of the lower clamping seat 311, and as shown...Figure 2 As shown, the upper clamping seat 312 is disposed between the two side plates 12 and the two ends of the upper clamping seat 312 extend into the two guide grooves 123 on both sides respectively.

[0062] The pull-out tool of this application limits the moving direction of the clamping seat 31 by providing a guide groove 123 extending along the second direction Y on the side plate 12, so that the moving path of the connector during pull-out is perpendicular to the surface of the base and thus avoids damage to the electrical connection between the connector and the base.

[0063] In some embodiments, the clamping structure 3 includes a clamping base 31. A clamping arm 32 is disposed on the clamping base 31. The clamping base 31 has a connecting groove 3121. The first end of the operating handle 2 extends into the connecting groove 3121, and the first end of the operating handle 2 is provided with a through connecting hole 22. The connecting post 6 passes through the connecting hole 22 and is connected to the connecting groove 3121.

[0064] The clamping structure 3 of this application embodiment has a clamping seat 31 with a connecting groove 3121, which allows the first end of the operating handle 2 to extend into the connecting groove 3121 and connect with the clamping seat 31 through the connecting post 6, making the connection more reliable and thus improving the reliability of the pulling tool.

[0065] In order to achieve rapid positioning between the clamping arm 32 and the clamping seat 31, in some embodiments, the clamping seat 31 has a recess 3111 and the clamping arm 32 has a protrusion 322, with the protrusion 322 and the recess 3111 engaging in a convex-concave fit.

[0066] By providing a protrusion 322 on the clamping arm 32 and a recess 3111 on the clamping seat 31, the position of the clamping arm 32 can be accurately positioned by engaging the protrusion 322 with the recess 3111 when connecting the clamping arm 32.

[0067] like Figure 3 As shown, the clamping structure 3 includes a clamping base 31 and two clamping arms 32. The clamping base 31 includes an upper clamping base 312 and a lower clamping base 311. The lower clamping base 311 is a bent plate structure, which includes a connecting seat to the upper clamping base 312 and a connecting plate arranged perpendicular to the connecting seat. The clamping arms 32 are connected to the connecting plate. The clamping arms 32 are provided with two first through holes, and the connecting plate is also provided with two second through holes. The positions of the two first through holes and the two second through holes correspond to the positions of the clamping arms 32 and the connecting plate using bolts or other connecting components.

[0068] Furthermore, the protrusion 322 is disposed between the two first through holes, and the recess 3111 is disposed between the two second through holes. This allows for accurate positioning of the clamping arm 32 through the interlocking of the protrusion 322 and the recess 3111. Then, a connector is inserted between the first and second through holes to connect the clamping arm 32 to the clamping seat 31, thus eliminating the need for repeated positioning and facilitating installation. In some embodiments, such as... Figure 2 and Figure 3 As shown, the pulling tool also includes a return spring 4. The return spring 4 is disposed between the operating handle 2 and the base 1.

[0069] like Figure 2 As shown, when the first end of the operating handle 2 is pressed to pull out the connector, the return spring 4 is compressed under pressure. Therefore, after the connector is pulled out, the operating handle 2 can return to its original position under the restoring force of the return spring 4. Moreover, the setting of the return spring 4 makes the operating handle 2 and the base 1 mutually support each other, generating mutual thrust during operation to achieve the auxiliary force function.

[0070] During the research, the inventors also discovered that because the gap between the side of the connector and the housing of the base is very small, and a latching structure 110 is provided within this gap, when pulling out the connector by hand, it is necessary to insert one's hand into the very small gap to unlock the latching structure 110 before the connector can be pulled out. To address this problem, in some embodiments, the clamping structure 3 is configured to move along the third direction Z on the surface of the base towards the connector so that the connector gradually enters the clamping space. The clamping structure 3 also includes an unlocking part. The unlocking part is configured to press the latching structure 110 on the connector 100 inward during the movement of the clamping structure along the third direction Z towards the connector, thereby disengaging the latching structure 110.

[0071] In this embodiment, the clamping structure 3 moves towards the connector to gradually clamp the connector, while the unlocking part presses the latching structure 110 inward. This effectively achieves both unlocking and clamping in one action, thus simplifying the use of the pull tool and improving efficiency. Furthermore, the pull tool utilizes a small gap to unlock the mechanical latching structure.

[0072] In some embodiments, the clamping structure 3 is configured to move along the third direction Z on the surface of the substrate toward the connector so that the connector gradually enters the clamping space. The clamping arm 32 has a clamping surface 321 on the side near the connector. The clamping surface 321 is configured to be inclined relative to the third direction Z so that as the clamping structure moves toward the connector, the distance between the clamping surface 321 and the connector 100 gradually decreases, thereby causing the snap-fit ​​structure on the connector 100 to disengage.

[0073] In this embodiment, the clamping surface 321 of the clamping arm 32 is set as an inclined surface. When moving towards the connector, the inclined surface acts on the latching structure. The closer to the connector, the closer the inclined surface acts on the latching structure is to the inside, thus causing the latching structure to disengage from the latching hole. Therefore, the unlocking part of this embodiment can be achieved by using only an inclined surface, which is simple in structure and easy to process.

[0074] In some embodiments, the surfaces of the base 1, the clamping structure 3, and the operating handle 2 are provided with an insulating protective layer.

[0075] The insulating protective layer effectively prevents connector damage caused by electric arcing during connector removal and removal. Furthermore, the surface of the insulating protective layer can be designed with an uneven surface, which further enhances its anti-slip properties during use.

[0076] The following is based on Figures 1 to 3 A detailed description of a connector puller according to a specific embodiment of this application will be provided.

[0077] like Figure 1 As shown, connector 100 is mounted on base 200. Specifically, the bottom surface of connector 100 near base 200 is connected to base 200. Therefore, to remove connector 100, it is necessary to move connector 100 away from base 200 to pull it out. See details... Figure 1 In terms of direction, connector 100 should be pulled out in the direction away from the paper.

[0078] In using such Figure 2 The pulling tool shown Figure 1 When disassembling the connector 100 shown, the pulling tool needs to be moved downward along the third direction Z so that the clamping structure of the pulling tool clamps the connector 100 on both sides in the first direction X to clamp the connector 100. Then, the clamping structure 3 is moved away from the base 200 in the direction (second direction Y) to pull out the connector 100.

[0079] like Figure 2As shown, the pulling tool in this embodiment includes a base 1, an operating handle 2, a clamping structure 3, a return spring 4, a rotating shaft 5, and a connecting post 6.

[0080] The base 1 includes a base plate 11, two side plates 12, and a limiting part 13. The two side plates 12 are respectively connected to both sides of the base plate 11 and enclose a groove-shaped cavity. The limiting part 13 is disposed at the upper end of the base plate 11. The limiting part 13 is spaced apart from the operating handle 2, so that the limiting part 13 limits the operation handle 2 when it is pressed and moved closer to the base 1.

[0081] like Figure 3 As shown, a countersunk hole is provided on the base plate 11, and correspondingly, a countersunk hole is also provided on the surface of the operating handle 2 near the base plate 11, and the return spring 4 abuts against the two countersunk holes.

[0082] The operating handle 2 is disposed within the cavity. The operating handle 2 is rotatably connected to the two side plates 12 via a rotating shaft 5. The second end of the operating handle 2 is connected to the clamping structure 3 via a connecting post 6.

[0083] The clamping structure 3 includes a clamping base 31 and a clamping arm 32. The clamping base 31 is connected to the second end of the operating handle 2 via a connecting post 6.

[0084] In this embodiment, the puller moves along the Z-direction to gradually approach the connector 100, causing the two clamping arms of the clamping structure 3 to clamp onto both sides of the connector. The clamping surfaces of the clamping arms are beveled to unlock the connector's snap-fit ​​connection. Unlocking principle: As the puller moves along the contact surface towards the connector, the clamping surfaces of the clamping arms contact the snap-fit. The beveled design of the clamping surfaces pushes the snap-fit ​​structures on both sides towards the center during the movement, thereby releasing the connection between the connector and the housing.

[0085] Specifically, the bottom end of the snap-fit ​​structure is engaged in the snap hole of the housing, and the upper end of the snap-fit ​​structure protrudes from the housing, thus providing space for the clamping arm to function.

[0086] After the pulling tool is inserted into place, press the second end of the operating handle 2, as shown. Figure 2 As shown, a force F1 is applied to the operating handle 2 to rotate the operating handle in the direction indicated by arrow M, thereby applying a force F2 to the connector opposite to the direction of connector insertion. Under the premise of unlocking the latch, the connector can be pulled out.

[0087] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
