Description

Technical Field

[0001] This utility model belongs to the field of testing tool technology, and in particular relates to a testing fixture for bent connectors. Background Technology

[0002] In the field of new energy batteries, conductive connectors are needed to connect battery packs or batteries with other components. To reduce space occupation, connectors are adapted to the shape of the space by bending. In order to ensure that the two ends of the connector can be properly connected, there are corresponding requirements for the accuracy of the bending position and bending angle of the bent connector. Based on this requirement, the applicant designed a testing fixture for Z-shaped double-bending connectors to enable rapid detection of the angle of the two bending parts and the length of the middle area. Utility Model Content

[0003] The purpose of this utility model is to provide a testing fixture for bent connectors to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a testing fixture for bent connectors, comprising a placement platform, wherein a bending angle testing block is provided on the placement platform, the first segment of the double-bent connector is placed on the placement platform, the middle segment of which is attached to the side of the testing block, and the third segment of which overlaps the top surface of the testing block. The placement platform is equipped with a clamping fixture for pressing the connector onto the placement platform. A middle section height detection slider slides on the top surface of the bending angle detection block. A height detection groove is opened on the side wall of the middle section height detection slider near the connector. When the middle section height detection slider slides on the top surface of the bending angle detection block, if the third section of the double-bent connector passes through the height detection slot without any obstruction, the product is qualified; if it cannot pass or obstruction occurs during the passage, the product is unqualified.

[0005] Preferably, the bending angle detection block is provided with a guide limiting component, and the middle section height detection slider moves back and forth in a fixed direction under the guiding and limiting action of the guide limiting component.

[0006] Preferably, a fixing member is provided on the bending angle detection block, which can fix the middle section height detection slider on the bending angle detection block.

[0007] Preferably, the bending angle detection block is further provided with a placement groove, and the fixing member can be placed in the placement groove.

[0008] Preferably, the placement platform is also vertically provided with at least two sets of positioning pins, each set of positioning pins including two, and the first section of the double-bent connector is placed between each set of positioning pins.

[0009] Preferably, the positioning pin includes a guide section and a width detection section distributed in the vertical direction, the width detection section being mounted on the placement platform.

[0010] Preferably, the placement platform has an installation positioning groove extending downwards from the top, the bottom surface of the bending angle detection block is provided with an installation positioning block that can be embedded in the installation positioning groove, the placement platform has a first connecting fixing hole that extends to the installation positioning groove, the installation positioning block has a second connecting fixing hole, and a second fixing member can be inserted into the first connecting fixing hole and the second connecting fixing hole to fix the installation positioning block in the installation positioning groove.

[0011] Preferably, the clamping fixture includes a pressing body and a pressing head, wherein the pressing head is made of rubber.

[0012] The beneficial effects of this utility model are as follows: This solution sets up a bending angle detection block. After the first section of the double-bent connector is placed flat on the placement platform, the bending angle is determined by observing the degree of fit between the middle section of the double-bent connector and the bending angle detection block. At the same time, by setting up a middle section height detection slider, if the third section of the connector can pass through the height detection groove without obstruction, it means that the height of the middle section meets the standard and the bending angle of the third section meets the standard. This inspection tool can simultaneously detect the height of the middle section of the connector and the bending angle of the two bending parts, effectively ensuring the efficiency of the inspection. Among them, fixing the segment height detection slider on the bending angle detection block by using a fastener can avoid loss and collision during the movement of the fixture; By setting positioning pins, the width of the first section of the connector can also be detected simultaneously; if it is too wide, it cannot be inserted.
