Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] In a vehicle's battery module, high-voltage power distribution equipment such as BDU (Battery Disconnect Unit), PDU (Power Distribution Unit), and BMU (Battery Management Unit) are typically required to manage the power distribution of the battery.

[0038] High-voltage power distribution equipment, batteries, and external electrical control equipment are often connected by wire harnesses. To ensure the effectiveness and reliability of the connection, different connection terminals are set on the wire harness for different equipment, such as hole terminals, plug-in male terminals, and plug-in female terminals. All types of connection terminals need to be connected and fixed, but there is currently no corresponding clamping and fixing device.

[0039] In view of this, embodiments of this application provide a terminal clamping fixture for wire harness inspection, including a substrate 10, a first clamping member 20, a second clamping member 30, and a third clamping member 40; the first clamping member 20 includes a first base 21, a first crimping member 22, and a first connecting terminal 23. The first base 21 is connected to the substrate 10 and has a clamping groove 211 with an opening away from the substrate 10. The first base 21 has a first opening 212 on the side facing the first crimping member 22, and the first opening 212 communicates with the clamping groove 211. The first crimping member 22 is connected to the substrate 10 and can move toward the first opening 212. The first connecting terminal 23 communicates with the first crimping member 22. A crimping member 22 is connected and disposed on the side of the first crimping member 22 near the first base 21, facing the first opening 212; the second clamping member 30 includes a second base 31, a second crimping member 32, and a second connecting terminal 33. The second base 31 is connected to the substrate 10, the second connecting terminal 33 is connected to the second base 31, and the second crimping member 32 is connected to the second base 31 and can move toward the second connecting terminal 33; the third clamping member 40 includes a third base 41 and a third connecting terminal 42. The third base 41 is connected to the substrate 10 and has a insertion hole 411. The third connecting terminal 42 is partially inserted through the insertion hole 411. In this application, a first clamping member 20, a second clamping member 30, and a third clamping member 40 are provided on the substrate 10 to clamp and fix various connecting terminals on wire harnesses such as plug-in female terminals 50, hole terminals 70, and plug-in male terminals 60, so as to clamp and fix the wire harness and perform wire harness testing.

[0040] In some embodiments, please refer to Figure 9 , Figure 10 and Figure 11 , Figure 9 This is a perspective view of the plug-in female terminal block 50. Figure 10 This is a perspective view of the plug-in male terminal 60. Figure 11This is a perspective view of the hole-type terminal 70. The hole-type terminal 70 in this application is a sheet-like terminal with a connection hole 71. The plug-in male terminal 60 is a connection terminal with the wiring terminal 61 protruding outward. The plug-in female terminal 50 is a connection terminal with an enlarged plug interface 52 and a limiting boss 51 on the outer side wall.

[0041] In some embodiments, please refer to Figure 1 and Figure 2 , Figure 1 This is a perspective view of a terminal clamping fixture for wire harness inspection provided in an embodiment of this application. Figure 2 This is a perspective view of the first clamping member 20 in the terminal clamping fixture for wire harness testing provided in this application embodiment. The first clamping member 20 includes a support plate, a first base 21, a first crimping member 22, and a first connecting terminal 23 disposed on the support plate. The support plate is fixedly disposed on the substrate 10, and the first base 21 is fixedly disposed on the substrate 10 and disposed on the side of the support plate away from the substrate 10 to clamp and fix the plug-in female terminal 50. The first crimping member 22 is slidably connected to the support plate by means of a slider rail and is disposed on the side of the support plate away from the substrate 10. The sliding direction of the first crimping member 22 is towards the first clamping member 20. The first connecting terminal 23 is connected to the first crimping member 22 and is disposed on the side of the first crimping member 22 near the first base 21 along the movement direction of the first crimping member 22, so that the first connecting terminal 23 can be connected to the plug-in female terminal 50 by sliding the first crimping member 22.

[0042] In some embodiments, please refer to Figure 2 and Figure 4 , Figure 2 This is a perspective view of the first clamping member 20 in the terminal clamping fixture for wire harness inspection provided in an embodiment of this application. Figure 4 This is a perspective view of the first base 21 of the terminal clamping fixture for wire harness testing provided in an embodiment of this application. The first base 21 has a clamping groove 211 on the side away from the substrate 10 for clamping and fixing the plug-in female terminal 50. Specifically, the first base 21 has a first opening 212 on the side facing the first crimping member 22. The first opening 212 communicates with the clamping groove 211, and the movement direction of the first crimping member 22 is towards the first opening 212, while the first connecting terminal 23 faces the first opening 212. It can be understood that the open end, i.e., the plug-in end, of the plug-in female terminal 50 is located at the first opening 212 and faces the first connecting terminal 23, so that when the first crimping member 22 is pushed towards the first base 21, the first connecting terminal 23 is connected to the plug-in female terminal 50 via the first crimping member 22.

[0043] In some embodiments, please refer to Figure 2 and Figure 4 , Figure 2This is a perspective view of the first clamping member 20 in the terminal clamping fixture for wire harness inspection provided in an embodiment of this application. Figure 4 This is a perspective view of the first base 21 of the terminal clamping fixture for wire harness testing provided in an embodiment of this application. The first base 21 also includes a first protrusion 213, which is disposed in the clamping groove 211 and on the side wall of the clamping groove 211 near the first opening 212. Specifically, two sets of first protrusions 213 may be provided, with the two sets of first protrusions 213 respectively located on two opposite side walls of the clamping groove 211. Understandably, the two first protrusions 213 clamp and fix the outer wall of the plug-in female terminal 50, and at the same time, along the movement direction of the first crimping member 22, the enlarged interface of the first crimping member 22 abuts against the two first protrusions 213, so that when the first crimping member 22 drives the first connecting terminal 23 to connect to the plug-in female terminal 50, the two first protrusions 213 abut against the enlarged interface of the plug-in female terminal 50, thus preventing the plug-in female terminal 50 from shifting.

[0044] In some embodiments, please refer to Figure 2 and Figure 4 , Figure 2 This is a perspective view of the first clamping member 20 in the terminal clamping fixture for wire harness inspection provided in an embodiment of this application. Figure 4 This is a perspective view of the first base 21 of the terminal clamping fixture for wire harness inspection provided in an embodiment of this application. The first protrusion 213 has a limiting groove 2131, the extending direction of which intersects the movement direction of the first crimping member 22. The limiting groove 2131 has a second opening 2132 facing the clamping groove 211. Specifically, the extending direction of the limiting groove 2131 is orthogonal to the movement direction of the first crimping member 22. Understandably, when the plug-in female terminal 50 is connected, the interface is located at the first opening 212, and the limiting boss 51 of the plug-in female terminal 50 is located in the limiting groove 2131. This allows the limiting groove 2131 and the limiting boss 51 to further limit the displacement of the plug-in female terminal 50 when the first crimping member 22 drives the first connecting terminal 23 to connect to the plug-in female terminal 50. At the same time, when the first crimping member 22 drives the first connecting terminal 23 to retract and release the connection between the first connecting terminal 23 and the plug-in female terminal 50, the limiting groove 2131 and the limiting boss 51 limit the displacement of the plug-in female terminal 50, preventing the first crimping member 22 from pulling the plug-in female terminal 50 out of the limiting groove 2131 through the first opening 212 via the first connecting terminal 23.

[0045] In some embodiments, please refer to Figure 3 , Figure 3This is a cross-sectional perspective view of the first crimping member 22 in the terminal clamping fixture for wire harness testing provided in this application embodiment. The first crimping member 22 has a first receiving groove 221, the opening of the first receiving groove 221 facing the first opening 212. The shape and size of the first receiving groove 221 are matched with the plug-in end of the plug-in female terminal 50 to accommodate the insertion of the plug-in end of the plug-in female terminal 50. A first connecting terminal 23 is disposed in the first receiving groove 221.

[0046] In some embodiments, please refer to Figure 3 , Figure 3 This is a cross-sectional perspective view of the first crimping member 22 in the terminal clamping fixture for wire harness testing provided in this application embodiment. The first crimping member 22 also has a first wiring hole 222, which is a hole with both ends open, and the first wiring hole 222 communicates with the first receiving groove 221. Specifically, in this application, the first wiring hole 222 is a straight hole and is arranged along the movement direction of the first crimping member 22. It can be understood that the first wiring hole 222 is used to insert and fix the first connecting terminal 23, and at the same time, it allows the wire connecting the first connecting terminal 23 to pass through and connect to the first connecting terminal 23.

[0047] In some embodiments, please refer to Figure 2 , Figure 2 This is a perspective view of the first clamping member 20 in the terminal clamping fixture for wire harness testing provided in an embodiment of this application. The first clamping member 20 also includes a thrust member 24. Along the moving direction of the first crimping member 22, the thrust member 24, the first crimping member 22, and the first base 21 are spaced apart to provide a thrust to the first crimping member 22 toward the first base 21 through the thrust member 24.

[0048] In some embodiments, please refer to Figure 2 , Figure 2This is a perspective view of the first clamping member 20 in the terminal clamping fixture for wire harness testing provided in this application embodiment. The thrust member 24 is hinged to the base plate 10, achieving a rotatable connection between the thrust member 24 and the base plate 10. The rotation plane of the thrust member 24 is parallel to the line of motion of the first pressing member 22, so that the rotation of the thrust member 24 pushes against the first pressing member 22, causing the first pressing member 22 to move towards the first base 21. Specifically, the thrust member 24 includes a second protrusion 241, which is disposed on the side of the thrust member 24 near the first pressing member 22. The distance from different positions of the outer contour line of the second protrusion 241 to the rotation center of the thrust member 24 is different, so that when the thrust member 24 is rotated, the outer contour lines of different positions of the second protrusion 241 contact the first pressing member 22, thereby pushing the first pressing member 22 towards the first base 21. For example, the second protrusion 241 can be a cam or an eccentric wheel. Understandably, the thrust member 24 and the first pressing member 22 are in a pushing state. In the pushing state, the second protrusion 241 pushes the first pressing member 22 toward the first base 21 along the moving direction of the first pressing member 22.

[0049] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 6 , Figure 1 This is a perspective view of a terminal clamping fixture for wire harness inspection provided in an embodiment of this application. Figure 5 This is a perspective view of the second clamping member 30 in the terminal clamping fixture for wire harness inspection provided in an embodiment of this application. Figure 6 This is an exploded view of the second crimping member 32, the fixing block 34, and the handle 35 in the terminal clamping fixture for wire harness testing provided in this embodiment of the application. The second clamping member 30 includes a second base 31, a second crimping member 32, and a second connecting terminal 33. The second base 31 is fixedly connected to the substrate 10 by bolts or other means. The second connecting terminal 33 is connected to the second base 31 and is disposed on the side of the second base 31 away from the substrate 10. The second crimping member 32 is connected to the second base 31 and can move toward the second connecting terminal 33. It can be understood that the second connecting terminal 33 passes through the connecting hole 71 of the hole terminal 70 and connects to the hole terminal 70. At the same time, the second crimping member 32 crimps and fixes the hole terminal 70 onto the second base 31, thereby realizing the connection and fixation of the hole terminal 70.

[0050] In some embodiments, please refer to Figure 5 and Figure 6 , Figure 5 This is a perspective view of the second clamping member 30 in the terminal clamping fixture for wire harness inspection provided in an embodiment of this application. Figure 6This is an exploded view of the second crimping member 32, the fixing block 34, and the handle 35 in the terminal clamping fixture for wire harness testing provided in this application embodiment. The second clamping member 30 further includes the fixing block 34, which is disposed on the side of the second base 31 away from the substrate 10 and is fixedly connected to the second base 31 by bolts. The fixing block 34 has a sliding hole 341, which is disposed on the side of the fixing block 34 near the second base 31. The sliding hole 341 has a third opening 342 facing the second connecting terminal 33. The second crimping member 32 is disposed in the sliding hole 341 and can extend from the third opening 342 toward the second connecting terminal 33 to crimp the defined hole type terminal 70.

[0051] In some embodiments, please refer to Figure 5 , Figure 6 and Figure 7 , Figure 5 This is a perspective view of the second clamping member 30 in the terminal clamping fixture for wire harness inspection provided in an embodiment of this application. Figure 6 This is an exploded view of the second crimping member 32, the fixing block 34, and the handle 35 in the terminal clamping fixture for wire harness testing provided in the embodiments of this application. Figure 7 This is a perspective view of the second crimping member 32 in the terminal clamping fixture for wire harness testing provided in this application embodiment. The second clamping member 30 also includes a handle 35, which is connected to the second crimping member 32. When the hole terminal 70 needs to be crimped and fixed, the second crimping member 32 is driven to extend from the sliding hole 341 through the third opening 342 to crimp and fix the hole terminal 70 on the second base 31. When it is necessary to load or unload the hole terminal 70, the second crimping member 32 is brought into the sliding hole 341 to release the restriction on the hole terminal 70, facilitating the loading and unloading of the hole terminal 70 on the second clamping member 30.

[0052] In some embodiments, please refer to Figure 6 and Figure 7 , Figure 6 This is an exploded view of the second crimping member 32, the fixing block 34, and the handle 35 in the terminal clamping fixture for wire harness testing provided in the embodiments of this application. Figure 7 This is a perspective view of the second crimping member 32 in the terminal clamping fixture for wire harness testing provided in this application embodiment. The fixing block 34, on the side away from the second base 31, also has a guide hole 343. The guide hole 343 communicates with the sliding hole 341 and is formed along the movement direction of the second crimping member 32. The handle 35 is connected to the second crimping member 32 and at least partially passes through the guide hole 343 to guide and limit the stroke of the handle 35. Specifically, along the direction in which the guide hole 343 communicates with the sliding hole 341, the cross-section of the guide hole 343 is a monolithic circle, and the direction of the straight side of the monolith is the movement direction of the handle 35.

[0053] In some embodiments, please refer to Figure 6 , Figure 6 This is an exploded view of the second crimping member 32, the fixing block 34, and the handle 35 in the terminal clamping fixture for wire harness testing provided in this embodiment of the application. The second clamping member 30 in the wire harness clamping fixture provided in this embodiment of the application further includes an elastic member for pushing the second crimping member 32 outwards. Specifically, the elastic member is disposed in the sliding hole 341, one end of the elastic member is connected to the fixing member, and the other end is connected to the second clamping member 30. The extension and retraction direction of the elastic member is set along the sliding direction of the second crimping member 32, so as to continuously push the second clamping member 30 outwards from the sliding hole 341 through the third opening 342, thereby keeping the second clamping member 30 pressed and fixed against the hole-type terminal 70.

[0054] In some embodiments, please refer to Figure 1 and Figure 8 , Figure 1 This is a perspective view of a terminal clamping fixture for wire harness inspection provided in an embodiment of this application. Figure 8 This is a cross-sectional perspective view of the third base 41 in the terminal clamping fixture for wire harness testing provided in this application embodiment. The third clamping member 40 in the terminal clamping fixture for wire harness testing provided in this application embodiment includes a third base 41 and a third connecting terminal 42. The third base 41 is fixedly connected to the base plate 10 by bolts. The third base 41 has a insertion hole 411, which is located on the side of the third base 41 away from the base plate 10. The third connecting terminal 42 partially passes through the insertion hole 411. Understandably, the protruding terminal 61 of the plug-in male terminal 60 is inserted into the insertion hole 411 and contacts the third connecting terminal 42 in the insertion hole 411, thereby achieving the connection and fixation of the plug-in male terminal 60.
