Description

Technical Field

[0001] This utility model relates to the field of charging clip technology, and more specifically, to a universal terminal block charging clip tool. Background Technology

[0002] During the vehicle assembly process, when the body instrument panel is being tested for electrical components, the battery is usually not yet installed, and an external power source is required. In this case, the electrodes need to be connected to the vehicle's terminals. For example... Figure 1 As shown, the vehicle terminal 3 has two structures: a terminal screw hole 31 and a terminal screw 32. The wire terminals are pressed onto the metal plate 33 of the terminal 3 by bolts and nuts to achieve conductivity. At this time, the terminal 3 is not connected to the power supply and can only be connected by a power connector clamp.

[0003] The existing charging caliper achieves fixation and conductivity by inserting a locking pin into the screw hole 31. At this point, the locking pin of the charging caliper contacts the screw hole of the terminal 3, providing the current required for voltage detection. However, since the terminal 3 has a threaded structure, this power supply method relies on the cylindrical surface of the locking pin contacting the internal thread of the terminal 3. The contact area between the cylindrical surface and the threaded hole is small, leading to unstable contact. Even slight disturbances to the charging caliper can easily cause poor contact, resulting in power interruptions and forcing the entire voltage detection process to restart. This also easily damages the voltage detection equipment. This solution has poor reliability and significantly affects the normal operation of the instrument voltage detection process. Furthermore, this solution is only applicable to single-screw-hole terminal structures and is completely unsuitable for vehicles with only a single screw stud 32 structure, resulting in poor versatility. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, this utility model provides a universal terminal charging clamping tool. A detachable charging pin is provided at the free end of the first jaw, and a slot penetrating the free end of the second jaw is provided on the clamping surface of the second jaw. The charging pin is used to conduct electricity by contacting the screw hole of the screw-hole type terminal, and the slot is used to clamp the screw of the stud type terminal for conduction. It can be applied to both stud type terminals and screw hole type terminals, and has universality.

[0005] The technical problem solved by this utility model is addressed by the following technical solution:

[0006] A universal terminal block charging clamping tool includes a first clamp body and a second clamp body hinged together. The first clamp body includes a first handle and a first jaw, and the second clamp body includes a second handle and a second jaw.

The clamping surface of the second jaw is provided with a slot that penetrates the free end of the second jaw.

[0007] Furthermore, the charging pin is provided with a flange, which is close to or abuts against the clamping surface of the first jaw; the length of the charging pin extending out of the flange is not greater than the depth of the wiring screw hole; preferably, the flange is threaded to the charging pin, and provides a stable current required for vehicle body electrical detection through the metal sheet surface of the flange end face contacting the end face of the terminal block.

[0008] Furthermore, the charging pin is threaded onto the first jaw for easy disassembly and replacement.

[0009] Furthermore, the free end of the first jaw is provided with a hook protruding toward the second jaw. The hook is not higher than the end face of the flange near the second jaw and can be used to engage the bottom surface of the outer shell reinforcing rib.

[0010] Furthermore, the first and second clamping bodies are hinged in an A-shape; the charging pin is vertically positioned on the clamping surface of the first jaw, allowing the first and second jaws to open to a parallel state.

[0011] Furthermore, when the first jaw and the second jaw are in a parallel state, the distance between the charging pin axis and the free end face of the second jaw is adapted to the distance between the wiring screw hole axis and the outer wall of the charging housing; the distance between the inner side of the hook and the free end face of the second jaw is adapted to the distance between the metal piece of the wiring stud and the bottom surface of the housing reinforcing rib, so that the tool can maintain stable clamping.

[0012] Furthermore, the first jaw includes a first connecting plate and a first clamp, the first clamp being detachably mounted on the first connecting plate, and the charging pin being detachably mounted on the first clamp; the second jaw includes a second connecting plate and a second clamp, the second clamp being detachably mounted on the second connecting plate, and the slot being mounted on the second clamp, so that the first jaw and the second jaw can be easily and quickly disassembled and replaced.

[0013] Furthermore, the first connecting plate is provided with a first elongated hole, the extension direction of the first elongated hole is consistent with the extension direction of the first jaw, the first chuck is provided with a first threaded hole, and the first chuck is connected to the first connecting plate by a first bolt passing through the first elongated hole and the first threaded hole;

[0015] Furthermore, the slot may be a V-shaped slot, an arc-shaped slot, or a trapezoidal slot, which can accommodate different specifications of wiring studs.

[0016] Furthermore, a return spring is provided between the first clamp body and the second clamp body. The return spring pulls the first jaw and the second jaw to move in the closing direction, which can make the tool automatically and securely clamp.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments of this disclosure to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0029] In the description of this utility model, it should be noted that the term "comprising" and its variations indicate an open-ended inclusion, i.e., "including but not limited to". The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "and / or" when used to list two or more items means that it may include any one of the listed items, or any combination of two or more of the listed items.

[0030] This utility model provides a universal charging clamp tool with three terminals, see reference. Figure 2 and Figure 3 As shown, the clamping body includes a first clamping body 1 and a second clamping body 2 with hinged joints. The first clamping body 1 includes a first handle 11 and a first jaw 12. The second clamping body 2 includes a second handle 21 and a second jaw 22. The length of the first jaw 12 is greater than the length of the second jaw 22. The free end of the first jaw 12 is provided with a detachable charging pin 121, which extends toward the second jaw 22. The clamping surface of the second jaw 22 is provided with a slot 221 that penetrates the free end of the second jaw 22.

[0031] refer to Figure 4As shown, when supplying power to the screw-hole type terminal 3, hold the tool horizontally, open the first jaw 12 and the second jaw 22, and insert the charging pin 121 into the screw hole 31. The outer wall of the charging pin 121 contacts the screw hole 31, providing positioning and auxiliary power supply functions. Furthermore, the clamping surface of the first jaw 12 can be brought into contact with the metal plate 33 on the end face of the terminal 3 for conductivity, providing a stable current required for vehicle body electrical detection. Because the length of the first jaw 12 is greater than the length of the second jaw 22, there is a gap between the charging pin 121 and the free end face of the second jaw 22, allowing the second jaw 22 to clamp the outer shell reinforcing rib 5, completing the charging clamping and ensuring a stable clamping. (Reference) Figure 5 As shown, when supplying power to the stud-type terminal 3, remove the charging pin 121 in the power-off state, hold the tool vertically, open the first jaw 12 and the second jaw 22, and engage the slot 221 of the second jaw 22 with the terminal stud 32 to provide positioning and auxiliary power supply functions. Furthermore, the free end face of the second jaw 22 can be brought into contact with the metal plate 33 on the end face of the terminal 3 to conduct electricity, providing a stable current required for vehicle body electrical detection. Since the length of the first jaw 12 is greater than the length of the second jaw 22, the first jaw 12 can be used to clamp the charging housing 4 or the housing reinforcing rib 5, completing the charging clamping and ensuring a secure clamping. This tool is compatible with both screw-hole type and stud-type terminal 3, is universal, and has a simple and quick switching method. It is flexible and convenient to use, and can make good contact with the terminal 3 for stable power supply.

[0032] In some embodiments, reference Figures 2-4 As shown, the charging pin 121 is provided with a flange 122, which is close to or abuts against the clamping surface of the first jaw 12; the length of the charging pin 121 extending out of the flange 122 is not greater than the depth of the wiring screw hole 31. Figure 4 As shown, when the charging pin 121 is inserted into the wiring screw hole 31, the end face of the flange 122 can contact the metal plate 33 of the terminal block 3, providing a stable current required for vehicle body electrical detection. Preferably, the flange 122 is threaded to the charging pin 121, and the length of the charging pin 121 extending out of the flange 122 can be adjusted as needed to ensure that the charging pin 121 is inserted to a suitable depth into the wiring screw hole 31, which is sufficient to secure the charging pin 121 without exceeding the depth of the wiring screw hole 31, allowing the flange 122 to make stable contact with the metal plate 33 of the terminal block 3. The flange 122 can use a flat nut, making disassembly and assembly convenient and quick.

[0033] The tool is positioned by the threaded contact between the charging pin 121 and the wiring screw hole 31, and by the threaded contact between the slot 221 and the wiring stud 32. Then, the end face of the flange 122 contacts the metal plate 33 of the end face of the terminal 3, and the free end face of the second jaw 22 contacts the metal plate 33 of the end face of the terminal 3. This provides a stable current required for vehicle body electrical detection, thereby achieving planar contact power supply. The contact area is large, the charging loss is small, and the power supply is more stable and reliable.

[0034] In some embodiments, the charging pin 121 is threadedly connected to the first jaw 12. A threaded through hole can be provided on the first jaw 12, and the charging pin 121 can be threadedly connected to the threaded through hole, thereby detachably connecting the charging pin 121 to the first jaw 12. This facilitates quick and easy disassembly and replacement / maintenance. The charging pin 121 can be a stud, a single-ended bolt, etc. When supplying power to the stud-type terminal 3, it is necessary to remove the charging pin 121 and the flange 122. The charging pin 121 and the flange 122 can be connected to the outside of the first jaw 12 for safekeeping and to prevent loss.

[0035] In some embodiments, such as Figure 4 As shown, the free end of the first jaw 12 is provided with a hook 123 protruding towards the second jaw 22, and the hook 123 is not higher than the end face of the flange 122 near the second jaw 22. Figure 5 As shown, when supplying power to the stud-type terminal 3, removing the charging pin 121 and flange 122 allows the hook 123 to engage with the bottom surface of the outer casing reinforcing rib 5, ensuring stable and reliable clamping of the tool. The end face of the flange 122 near the second jaw 22 protrudes from or is flush with the hook 123. When supplying power to the screw-hole type terminal 3, this prevents the hook 123 from being too high and causing interference. When the charging pin 121 is inserted into the screw hole 31, the end face of the flange 122 can fit well with the metal piece 33 on the end face of the terminal 3, increasing the charging contact area.

[0036] In some embodiments, the first clamp body 1 and the second clamp body 2 are hinged in an A-shape. When the first handle 11 and the second handle 21 move in the opening direction, the first jaw 12 and the second jaw 22 move in the closing direction; when the first handle 11 and the second handle 21 move in the closing direction, the first jaw 12 and the second jaw 22 move in the opening direction. The first jaw 12 and the second jaw 22 can open to a roughly parallel state, facilitating clamping operations. Preferably, the charging pin 121 is vertically disposed on the clamping surface of the first jaw 12. When charging the screw-hole type terminal 3, the first jaw 12 and the second jaw 22 can be opened to easily insert the charging pin 121 into the terminal screw hole 31. At this time, the first jaw 12 is in a horizontal position, and the second jaw 22 can easily open to a horizontal position to clamp the bottom surface of the outer shell reinforcing rib 5. The large clamping area makes the tool clamp more securely.

[0037] Of course, the first clamp body 1 and the second clamp body 2 can also be configured with an X-shaped hinge. When the first handle 11 and the second handle 21 move in the opening direction, the first jaw 12 and the second jaw 22 move in the opening direction; when the first handle 11 and the second handle 21 move in the closing direction, the first jaw 12 and the second jaw 22 move in the closing direction. The first jaw 12 and the second jaw 22 can open to a suitable position to lock the terminal 3 and the outer shell reinforcing rib 5.

[0038] like Figure 1 As shown, the outer shell reinforcing rib 5 is basically parallel to the metal piece 33 on the end face of the terminal post 3. When clamping, it is better for the first jaw 12 and the second jaw 22 of the tool to be in a parallel state. When the first jaw 12 and the second jaw 22 are in a parallel state, the distance between the axis of the charging pin 121 and the free end face of the second jaw 22 is adapted to the distance between the axis of the wiring screw hole 31 and the outer wall of the charging shell 4; the distance between the inner side of the hook 123 and the free end face of the second jaw 22 is adapted to the distance between the metal piece 33 of the wiring screw 32 and the bottom surface of the outer shell reinforcing rib 5.

[0039] refer to Figure 4 As shown, when charging the screw-hole type terminal 3, the charging pin 121 is inserted into the screw hole 31 to avoid the second jaw 22 being too long and interfering with the charging housing 4. The distance between the axis of the charging pin 121 and the free end face of the second jaw 22 can be slightly greater than the distance from the axis of the screw hole 31 to the charging housing 4. The free end face of the second jaw 22 presses against the outer wall of the charging housing 4. After releasing the first handle 11 and the second handle 21, the second jaw 22 can clamp the housing reinforcing rib 5 as much as possible, so that the tool can maintain stable clamping.

[0040] refer to Figure 5As shown, when charging the stud-type terminal 3, the distance between the inner side of the hook 123 and the free end face of the second jaw 22 is slightly greater than the distance between the metal piece 33 of the terminal stud 32 and the bottom surface of the outer shell reinforcing rib 5. After releasing the first handle 11 and the second handle 21, the inner side of the hook 123 can engage with the bottom surface of the outer shell reinforcing rib 5, keeping the tool clamping stably. At the same time, it enables good and stable surface contact between the free end face of the second jaw 22 and the metal piece 33 of the terminal stud 32, improving conductivity stability and providing the stable current required for vehicle body electrical detection.

[0041] In some embodiments, the first jaw 12 includes a first connecting plate 124 and a first clamp 125, the first clamp 125 being detachably disposed on the first connecting plate 124, and the charging pin 121 being detachably disposed on the first clamp 125; the second jaw 22 includes a second connecting plate 222 and a second clamp 223, the second clamp 223 being detachably disposed on the second connecting plate 222, and the slot 221 being disposed on the second clamp 223. The first clamp 125 and the second clamp 223 can be easily and quickly disassembled and assembled, facilitating replacement and maintenance. This tool has a simple structure, good versatility, and can be used with simple modifications to standard straight-jaw charging pliers for automotive batteries, saving manufacturing costs.

[0042] Preferably, the first connecting plate 124 is provided with a first elongated hole, the extension direction of which is consistent with the extension direction of the first jaw 12, and the first chuck 125 is provided with a first threaded hole. The first chuck 125 is connected to the first connecting plate 124 by a first bolt passing through the first elongated hole and the first threaded hole. And / or, the second connecting plate 222 is provided with a second elongated hole, the extension direction of which is consistent with the extension direction of the second jaw 22, and the second chuck 223 is provided with a second threaded hole. The second chuck 223 is connected to the second connecting plate 222 by a second bolt passing through the second elongated hole and the second threaded hole. By screwing the first bolt through the first elongated hole into the first threaded hole, the first clamp 125 can be connected to the first connecting plate 124. The first threaded hole can be moved along the first elongated hole to adjust the length of the first jaw 12. Similarly, the length of the second jaw 22 can be adjusted through the second elongated hole, thereby adjusting the distance between the axis of the charging pin 121 and the free end face of the second jaw 22, and the height difference between the inner side of the hook 123 and the free end face of the second jaw 22, to adapt to different sizes of charging shell 4 and shell reinforcing rib 5.

[0043] In some embodiments, the slot 221 includes a V-shaped slot, an arc-shaped slot, or a trapezoidal slot. When supplying power to the stud-type terminal 3, it can accommodate different specifications of terminal studs 32, ensuring a stable clamping effect when the slot 221 engages with the terminal stud 32, providing stable positioning and auxiliary power supply functions. When supplying power to the screw-hole type terminal 3, it does not affect the stability of the second jaw 22 clamping the outer shell reinforcing rib 5.

[0044] In some embodiments, a return spring is provided between the first clamp body 1 and the second clamp body 2. The return spring pulls the first jaw 12 and the second jaw 22 to move in the closing direction. After releasing the first handle 11 and the second handle 21, the return spring can automatically and securely clamp the first jaw 12 and the second jaw 22, preventing poor contact when the charging pin 121 is inserted into the wiring screw hole 31, especially when clamping the wiring stud 32, preventing the tool from falling. Moreover, the operator does not need to manually maintain the clamping state, and can release the tool to avoid danger and reduce labor intensity. The return spring can be a helical spring or a torsion spring, etc. The two ends of the return spring are respectively connected to the first handle 11 and the second handle 21, or respectively connected to the first jaw 12 and the second jaw 22, as long as it can pull the first jaw 12 and the second jaw 22 to move in the closing direction, which is not limited here.

[0045] This tool can be used for vehicle electrical testing as well as during emergency vehicle repairs, providing convenient and quick power to the vehicle's instruments. 70% of instrument electrical test failures are caused by sudden power outages due to unstable clamping. This tool has a simple structure, stable clamping, and is less affected by shaking or impact, eliminating 70% of power outages caused by unstable clamping. The first-pass yield rate for electrical testing has increased from 85% to 99%.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
