[0002] In fields such as battery packs and power electronic equipment, connectors are crucial conductive components, and their overcurrent capacity directly affects the safety and stability of the entire system. To ensure the quality and reliability of connectors, overcurrent testing is typically required. Existing connector overcurrent testing methods and devices often suffer from the following problems:

[0003] The connection requires drilling holes at both ends: The existing method for testing the overcurrent of the connection is to drill holes at both ends of the connection and fix it to the copper busbar with bolts and nuts for testing. The test will damage the connection and is not conducive to cost control.

[0004] Poor versatility: Existing detection structures may have poor compatibility with connecting pieces of different sizes and shapes, requiring frequent fixture replacements or complex adjustments, which reduces detection efficiency and the versatility of the equipment.

[0005] Inconvenient operation: Some existing testing structures are complicated to operate in terms of installing and disassembling the connecting pieces and adjusting the clamping force, which is time-consuming and labor-intensive and not conducive to batch testing.

[0006] Therefore, there is still room for improvement in the existing technology for overcurrent detection of single connectors, and a new detection structure is needed that can provide a non-destructive connection, improve versatility and ease of operation. Utility Model Content

[0007] To address the aforementioned problems in the existing technology, the present invention aims to provide a novel single-unit connecting piece overcurrent detection structure, thereby solving the problems of poor versatility and inconvenient operation that current detection structures require drilling holes at both ends of the connecting piece for connection.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A novel single-piece connecting piece overcurrent detection structure includes: a base plate and two support frames embedded in a sliding groove on the upper surface of the base plate.

[0010] The upper end of the support frame is connected to the upper fixed plate by the first bolt, and a copper busbar is provided between the support frame and the upper fixed plate.

[0011] The front end of the copper busbar is connected to the clamping structure, and the connecting piece is fixed between the clamping structures on both sides for overcurrent detection.

[0012] Furthermore, the clamping structure includes an upper pressure block connected to the copper busbar and a lower pressure block corresponding to the upper pressure block, and the upper pressure block and the lower pressure block are connected by a third bolt.

[0013] Furthermore, the corresponding surfaces of the upper and lower pressure blocks are provided with anti-slip teeth.

[0014] Furthermore, the sliding groove is provided with two through slots, and one end of the locking bolt passes through the two through slots and is connected to the support frame in the sliding groove, while the other end of the locking bolt is located on the other side of the through slot.

[0015] Furthermore, the end of the copper busbar connected to the clamp structure is uniformly provided with threaded holes, and the copper busbar and the clamp structure are connected by a second bolt.

[0016] Furthermore, the upper and lower pressure blocks are provided with protrusions at one end of the connecting piece for clamping.

[0017] Beneficial effects: Compared with the prior art, this application has the following advantages:

[0018] 1. This testing structure can directly clamp the connecting piece onto the fixture structure for testing without drilling holes in the connecting piece, thus enabling testing without damaging the connecting piece and saving some costs.

[0019] 2. The sliding groove design on the base plate of this testing structure allows the support frame to slide within a certain range. Combined with the fixing bolts, this enables the entire structure to accommodate connecting pieces of different lengths, improving the equipment's versatility. Simultaneously, the clamping structure design facilitates quick installation and removal of the connecting pieces.

[0020] 3. The testing structure is compact and easy to operate. The use of bolted connections makes the connections between components more secure and reliable, reducing malfunctions caused by loose connections and extending the service life of the equipment. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1

[0027] Please see Figure 1 This invention provides a novel single-piece connecting piece overcurrent detection structure, comprising a base plate 1 and two support frames 2 embedded in a sliding groove 101 on the upper end face of the base plate 1. The base plate 1 serves as the fundamental support component of the entire detection structure, and its upper end face is provided with the sliding groove 101, which accommodates and guides the sliding of the support frames 2. The two support frames 2 are symmetrically arranged within the sliding groove 101, and they can move relative to each other along the sliding groove 101 to accommodate connecting pieces 8 of different lengths.

[0028] The upper end of the support frame 2 is connected to the upper fixing plate 4 via the first bolt 3, ensuring a stable connection between the two. The upper fixing plate 4 is located above the support frame 2, providing support and fixation for the copper busbar 5. A copper busbar 5 is provided between the support frame 2 and the upper fixing plate 4. The copper busbar 5 is the main conductive component, used to transmit current through the clamp structure 7 from the power supply to the connection piece 8 to be tested. The copper busbar 5 is typically made of copper material with high conductivity to reduce resistance loss.

[0029] The front end of the copper busbar 5 is connected to the clamping structure 7. The clamping structure 7 is a key component that directly contacts and clamps the connecting piece 8. The connecting piece 8 is fixed between the two clamping structures 7 for overcurrent detection. This means that the connecting piece 8 to be tested is clamped from both sides by the two clamping structures 7, forming a complete current loop, thus enabling overcurrent detection. This double-sided clamping method provides a uniform and stable clamping force, effectively preventing the connecting piece 8 from loosening or shifting during the testing process. Moreover, it eliminates the need for drilling holes in the connecting piece, allowing for testing without damaging it, thus saving costs.

[0030] Please see Figure 2The clamping structure 7 includes an upper clamping block 701 connected to the copper busbar 5 and a lower clamping block 702 corresponding to the upper clamping block 701. The upper clamping block 701 and the lower clamping block 702 are components that directly clamp the connecting piece 8. The upper clamping block 701 is connected to the copper busbar 5 by bolts or other fastening methods to ensure good electrical contact. The upper clamping block 701 and the lower clamping block 702 are connected by a third bolt 703. The third bolt 703 is used to adjust the distance between the upper clamping block 701 and the lower clamping block 702, thereby clamping or loosening the connecting piece 8. By tightening the third bolt 703, sufficient clamping force can be applied to the connecting piece 8 to ensure that it does not shift during overcurrent detection.

[0031] Furthermore, to improve clamping stability and prevent slippage of the connecting piece 8, anti-slip teeth are provided on the corresponding surfaces of the upper pressure block 701 and the lower pressure block 702. These anti-slip teeth can increase the friction between the clamping surface and the connecting piece 8, ensuring the stable fixation of the connecting piece 8 even under large current surges.

[0032] The upper pressure block 701 and the lower pressure block 702 are used to clamp one end of the connecting piece 8, which has a protrusion. These protrusions can better connect with the connecting piece 8, preventing the connecting piece 8 from being too protruding and inconvenient to clamp. The design of the protrusions can also be optimized according to the shape of the connecting piece 8 to achieve the best clamping effect.

[0033] Example 2

[0034] Please see Figure 1 and Figure 3 As shown, this embodiment further optimizes the fixing method of the support frame 2 on the base plate 1. Please refer to [link / reference]. Figure 3 The sliding groove 101 has two through grooves 102. These two through grooves 102 are parallel to the length of the sliding groove 101 and extend through the bottom of the sliding groove 101. One end of the locking bolt 103 passes through the two through grooves 102 and is connected to the support frame 2 inside the sliding groove 101, while the other end of the locking bolt 103 is located on the other side of the through groove 102. When it is necessary to fix the position of the support frame 2, by tightening the locking bolt 103, one end of it will press against the support frame 2, and the other end will provide a reaction force through the side wall of the through groove 102, thereby firmly locking the support frame 2 in a specific position inside the sliding groove 101. This design makes the positioning and locking of the support frame 2 more convenient and reliable, and can quickly adapt to the detection needs of connecting pieces 8 of different lengths.

[0035] Example 3

[0036] The end of the copper busbar 5 connected to the clamp structure 7 is uniformly provided with threaded holes 601. These threaded holes 601 are used to mate with bolts to achieve a tight connection between the copper busbar 5 and the clamp structure 7. The copper busbar 5 and the clamp structure 7 are connected by a second bolt 6. The second bolt 6 passes through a through hole on the clamp structure 7 and is screwed into the threaded hole 601 on the copper busbar 5, thus firmly connecting the two together. This bolted connection method ensures good electrical contact between the copper busbar 5 and the clamp structure 7, effectively reducing contact resistance and ensuring smooth current transmission, thereby improving the accuracy of overcurrent detection. Furthermore, users can adjust the position of the clamp structure 7 according to actual needs, improving its applicability.

[0037] Through the above-described structural design, this invention achieves stable, reliable, and low-contact-resistance overcurrent detection of the single connecting piece 8. The cooperation of the base plate 1, sliding groove 101, and support frame 2 gives the structure good versatility and adjustability; the copper busbar 5 ensures effective current transmission; and the clamping structure 7 (including upper pressure block 701, lower pressure block 702, third bolt 703, anti-slip teeth, and protrusions) provides precise and stable clamping of the connecting piece 8, ensuring the accuracy and safety of the detection.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
