Technical Field
[0001] This utility model belongs to the field of new energy battery testing technology, and in particular relates to a test line connector clamping and protection device. Background Technology
[0002] With the development of new energy vehicles, environmental testing of new energy vehicle batteries is becoming increasingly common. Before mass production of new energy battery packs (PACKs), multiple extreme condition tests are conducted, one of which is the series-parallel connection test of multiple modules within the PACK. Traditional clamping devices fix the test lead contacts with screws, requiring specialized insulating tools. After clamping, the exposed contacts are repeatedly wrapped with insulating tape; disassembly involves tearing off the insulating tape and unscrewing the screws. This tightening and loosening process wastes a significant amount of testing personnel's time, and the exposed test lead contacts also pose safety hazards. Therefore, how to fix the test lead contacts and whether the fixation provides protection is crucial, necessitating a test lead connector clamping and protection device to solve these problems. Utility Model Content
[0003] To overcome the shortcomings of the prior art, this invention provides a test lead connector clamping and protection device. This invention allows for convenient and quick fixation of the test lead contacts.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A test lead connector clamping and protection device includes a matching upper cover plate and a lower base. A clamping mechanism is installed in the lower base. The clamping mechanism includes a self-locking rod and a fixing member with a threaded hole. The self-locking rod includes a lower screw section and a locking rod hinged to the upper part of the upper screw section. The screw section is threadedly connected to the threaded hole of the fixing member. A groove is embedded in the middle of the lower base, and the fixing member is embedded in the groove.
[0006] Preferably, the upper cover plate has several first slot groups with upward openings on its periphery for the test lines to pass through. Each first slot group has two opposing first slots, and the first slots are U-shaped with downward openings. The lower base has several second slot groups with upward openings on its periphery along the groove. Each second slot group has two opposing second slots, and the second slots are U-shaped with upward openings. The positions of the first slot groups and the second slot groups are arranged in a one-to-one correspondence.
[0007] Preferably, the upper cover plate has two first slot groups on its periphery and the lower base has two second slot groups. The upper cover plate is installed on the lower base. After the first slot and its corresponding second slot overlap, they form a notch for the test line to pass through. The first slot and the second slot are staggered to better fit the misalignment around the contact when it is fixed.
[0008] Preferably, the fastener includes a cylindrical first nut and a square second nut that are fixedly connected from top to bottom, with a threaded hole on the first nut, the shape of the second nut matching the shape of the groove, and the top of the first nut located in the notch, so that the test lead contact is securely installed in the device.
[0009] Preferably, the bottom end of the lower base is provided with a threaded groove, which is threadedly connected to the tripod to facilitate the fixation of the entire device.
[0010] Preferably, the device further includes a foolproof component, with a first foolproof groove on the side wall of the upper cover plate and a second foolproof groove on the side wall of the lower base. The positions of the first foolproof groove and the second foolproof groove are on a straight line, which facilitates alignment during installation.
[0011] Preferably, the upper surface of the upper cover plate has a first upper protrusion, that is, the upper surface of the upper cover plate is convex upward to facilitate the outflow of liquid. The upper surface of the lower base has a second upper protrusion, that is, the upper surface of the lower base is convex to prevent water accumulation.
[0012] Preferably, anti-slip particles are evenly distributed on the outer surface and inside of the lower base, which both serve to increase friction. Specifically, the anti-slip particles on the outer surface of the lower base allow the lower base and the upper cover plate to fit together more closely, making the two more tightly assembled; the anti-slip particles inside the lower base prevent the test line from shifting within the lower base.
[0013] Both the top cover and the bottom base are made of polyvinyl chloride, and the interior can be filled with fire-resistant and insulating material to meet the high temperature and high humidity requirements during environmental testing.
[0014] The advantages of this utility model are:
[0015] (1) This utility model can place multiple test lead contacts into the lower base. The groove of the lower base is equipped with a nut. Then, the self-locking rod is aligned with the hole of the contact and inserted. After rotating several times, the self-locking rod is pressed down, and then the upper cover plate is put on to easily fix the test lead contacts. It is convenient and quick, and at the same time, it can clamp and protect the test lead contacts. It can also be operated for test lead contacts of different sizes, which is highly flexible. By using standard parts, the manufacturing cost and subsequent maintenance cost are reduced.
[0016] (2) This utility model is provided with a non-foolproof groove to facilitate alignment during installation; the upper surface of the upper cover plate is raised upward to facilitate the outflow of liquid; the lower base of the upper cover plate can serve as insulation, dustproof and waterproof, and the clamping mechanism can serve as quick clamping.

[0024] like Figure 1-5 As shown, a test lead connector clamping and protection device includes a protection mechanism, a clamping mechanism, and a support mechanism. The protection mechanism includes an upper cover plate 1 and a lower base 4. The upper cover plate 1 is hollowed out, and a groove is embedded in the center of the lower base 4. A fixing member 3 is embedded in the groove to elevate the contact and is designed to be detachable and replaceable. The self-locking rod 2 and the tripod 5 are common standard parts on the market. The upper cover plate 1 and the lower base 4 provide insulation, dustproofing, and waterproofing.
[0025] Specifically, the upper cover plate 1 has several first slot groups 103 with upward openings on its periphery for the test wires to pass through. Each first slot group 103 has two opposing first slots, which are U-shaped with downward openings. The lower base 4 has several second slot groups 402 with upward openings on its periphery along the groove. Each second slot group 402 has two opposing second slots, which are U-shaped with upward openings. The positions of the first slot groups 103 and the second slot groups 402 are arranged in a one-to-one correspondence. The dimensions of the second slots in the second slot groups 402 can be different to accommodate test wire widths of different sizes. The upper cover plate 1 has two first slot groups 103 on its periphery. The lower base 4 is not completely hollowed out. The lower base 4 has two second slot groups 402, and the upper cover plate 1 is installed on the lower base 4 to facilitate the insertion of test wires and to provide horizontal fixation.
[0026] The upper cover plate 1 has a first anti-misalignment groove 102 on its side wall, and the lower base 4 has a second anti-misalignment groove 403 on its side wall. The positions of the first anti-misalignment groove 102 and the second anti-misalignment groove 403 are aligned in a straight line to facilitate alignment during installation. The upper surface of the upper cover plate 1 has a first upper protrusion 101, that is, the upper surface of the upper cover plate 1 protrudes upward to facilitate the outflow of liquid. The upper surface of the lower base 4 has a second upper protrusion 401 to prevent water accumulation. Both the first and second grooves are staggered, that is, the first groove and its corresponding second groove overlap to form a notch for the test lead to pass through, so as to better fit the misalignment around the contact when fixing the contact and facilitate the fit of the test lead contact.
[0027] The clamping mechanism includes a fixing member 3 and a self-locking rod 2 mounted on the upper surface of the lower base 4. The fixing member 3 includes a cylindrical first nut 301 and a square second nut 302 fixedly connected from top to bottom, with a threaded hole in the first nut 301. The shape of the second nut 302 matches the shape of the groove. The fixing member 3 can be removed from the groove, facilitating the replacement of fixing members 3 with threaded holes of different sizes, thereby adapting to test lead contacts of different sizes. The top of the first nut 301 is located in a notch in a horizontal position, and the upper part of the first nut 301 can elevate the test lead contact. The lower part of the second nut 302 can fit into the interior of the lower base 4, and is also easy to disassemble. The self-locking rod 2 is a commercially available standard part, including a lower screw section and a locking rod hinged to the upper part of the screw section. The screw section is threadedly connected to the threaded hole of the fixing member 3, and can be matched according to requirements. Furthermore, for test leads with different apertures currently available on the market, in practical applications, only the matching self-locking rod 2 and fixing component 3 need to be replaced to achieve the original function, demonstrating cost reduction and efficiency improvement in the testing process. The fixing component 3 is installed on the upper surface of the lower base 4 of the device and serves as a quick clamping device.
[0028] The support mechanism includes a threaded groove 404 at the bottom of the lower base 4 and a tripod 5 threadedly connected to the threaded groove 404, allowing the lower base 4 to be fixed on the tripod 5 for easy lifting of the entire device. During humidity testing, the protection and clamping mechanisms are kept away from the ground to prevent water immersion. The tripod 5 is a standard commercial component to reduce the overall manufacturing cost of the device.
[0029] The working principle and usage procedure of this utility model are as follows: When connecting multiple test leads (2≤X≤4), first select a suitable self-locking rod 2 and fixing member 3 to fix the contact in the second slotted group 402 of the lower base 4. Then, align the self-locking rod 2 with the hole of the contact and insert it. After rotating it several times, the self-locking rod 2 will press the contact firmly. Then, press the rod part of the self-locking rod 2 to confirm that it is locked. Finally, after ensuring that the upper cover plate 1 and the foolproof assembly of the lower base 4 are on the same line, put the upper cover plate 1 on.
[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
