[0002] The terminals are usually connected to the wires by crimping them together with pressure. After the wires are connected to the terminals, it is usually necessary to test whether the connection is firm or not.

[0003] Existing connection strength testing devices only use two sets of clamping blocks to clamp the terminals and the two sides of the wire body respectively. Although the wire body can be effectively fixed, due to the flat shape of the terminals, this clamping method can easily cause the terminals to fall out of the clamping blocks. This is especially true for thicker cables and cables with greater pull-out force. The probability of the terminals falling out is greater, affecting the test results. Utility Model Content

[0004] The purpose of the utility model is to provide a terminal connection strength detection device, which can detect the connection strength between the terminal and the wire, improve the fixing effect of the terminal during testing, reduce the possibility of the terminal falling out from the fixed end of the device, and improve the detection effect.

[0007] A further improvement of the present invention is that the driving member includes a first rotating shaft vertically arranged on the side of the movable clamping block away from the fixed clamping block, the first rotating shaft is rotatably connected to a cam abutting the movable clamping block, and a handle is provided on one side of the cam.

[0008] A further improvement of the present invention is that a through-hole is provided on the table, and the placement plate includes a plate body located above the table and a connector slidably connected to the lower end of the table, one side of the connector is connected to the telescopic rod, and the other side is connected to the dynamometer.

[0010] A further improvement of the present invention is that the diameter extension line of the second rotating shaft parallel to the clamping surface of the fixed clamping block is located between the fixed clamping block and the movable clamping block.

[0014] The beneficial effects of the present invention are:

[0015] The utility model can fix the terminal and the wire by arranging a clamping ring and a wire clamping mechanism, so as to detect the connection strength between the two. By providing a clamping groove on the clamping ring, the diameter difference between the wire body and the terminal connection is utilized through the clamping groove to realize the positioning of the terminal during the pulling process, thereby improving the fixing effect of the terminal during testing, reducing the possibility of the terminal falling off from the fixed end of the device, and improving the detection effect.

[0016] The utility model drives the movable clamping block to close or separate from the fixed clamping block by a cam, thereby clamping and fixing the wire body, and can increase the speed of closing or separating the movable clamping block from the fixed clamping block, with fast adjustment speed and firm positioning.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: Combination Figures 1 and 2 As can be seen, a terminal connection strength testing device includes a table 1. A retaining ring 2 is rotatably mounted on one end of the table 1. A plurality of retaining grooves 3 of varying widths are circumferentially spaced at the upper end of the retaining ring 2. A placement plate 4 is slidably connected to the other end of the table 1. The placement plate 4 is provided with a wire clamping mechanism. A telescopic rod 5 is provided below the table 1, at the end away from the retaining ring 2, for moving the placement plate 4. A dynamometer 6, connected to the placement plate 4, is provided at the other end below the table 1. The gauge head of the dynamometer 6 is located on one side of the placement plate 4, allowing the operator to directly observe the gauge head reading when looking down. Preferably, the telescopic rod 5 is an electric telescopic rod.

[0024] The terminal is a conventional terminal with a ring and a tail sleeve. The wire is inserted into the tail sleeve and fixed by crimping. The ring is used to connect to other components. The terminal and wire are crimped together to form a connecting wire. Different slots 3 correspond to connecting wires of different wire diameters. The width of each slot 3 is larger than the wire diameter of the corresponding connecting wire and smaller than the diameter of the tail sleeve of the terminal crimped onto the wire.

[0025] The wire clamping mechanism includes a fixed clamping block 7 fixedly set on the placement plate 4, and a movable clamping block 8 slidably connected to the placement plate 4 is provided on one side of the fixed clamping block 7. The side of the movable clamping block 8 away from the fixed clamping block 7 is provided with a driving member for driving it to approach the fixed clamping block 7.

[0026] The driving member includes a first rotating shaft 9 vertically arranged on the side of the movable clamping block 8 away from the fixed clamping block 7. A cam 10 is rotatably connected to the first rotating shaft 9 and abuts against the movable clamping block 8. A handle 11 is provided on one side of the cam 10.

[0027] Tabletop 1 is provided with an opening 12. The placement plate 4 comprises a plate body 17 positioned above the plate 1 and a connector 13 slidably connected to the lower end of the plate 1. One side of connector 13 is connected to the telescopic rod 5, and the other side is connected to the dynamometer 6. The lower end surface of tabletop 1 is provided with slide rails jutting out of the opening 12. Connector 13 slidably connects to the slide rails and has a raised portion extending through the opening 12 to connect to plate body 17. Fixed clamping block 7, movable clamping block 8, and first rotating shaft 9 are provided on the surface of plate body 17.

[0028] A second rotating shaft 14 is vertically provided on the table 1 , and the snap ring 2 is coaxially rotatably connected to the second rotating shaft 14 . A gap having a height greater than the thickness of the plate body 17 is provided between the lower end surface of the snap ring 2 and the table.

[0029] The diameter extension line of the second rotating shaft 14 parallel to the clamping surface of the fixed clamping block 7 is located between the fixed clamping block 7 and the movable clamping block 8. Preferably, the fixed clamping block 7 and the movable clamping block 8 are both provided with latch teeth on the opposite sides.

[0030] A stabilizing frame 15 is provided on the placement plate 4, and the dynamic clamping block 8 is partially located in the stabilizing frame 15 and its two sides are slidingly connected to the inner side walls of the stabilizing frame 15. An extension portion 16 is provided on one side of the upper end of the stabilizing frame 15, and the upper end of the second rotating shaft 14 is rotatably connected to the extension portion 16. The cam 10 is located between the extension portion 16 and the placement plate 4.

[0031] When the cam 10 rotates counterclockwise, the distance between the movable clamping block 8 and the fixed clamping block 7 decreases. When the end of the handle 11 of the cam 10 approaches the clamping ring 2 as the cam 10 rotates, the movable clamping block 8 and the fixed clamping block 7 gradually separate. When the end of the handle 11 of the cam 10 moves away from the clamping ring 2 as the cam 10 rotates, the movable clamping block 8 and the fixed clamping block 7 gradually approach each other.

[0032] The working principle of a terminal connection strength detection device provided by the utility model is as follows: when in use, place the wire body of the connecting wire into the card slot 3 that is adapted to its wire diameter, pull the wire body so that the terminal at one end abuts against the inner wall of the clamping ring 2, and place the other end of the wire body between the movable clamping block 8 and the fixed clamping block 7. Turn the handle 11 to rotate the cam 10, and the cam 10 presses the movable clamping block 8 toward the fixed clamping block 7 to clamp and fix the wire body. Then start the telescopic rod 5, and the telescopic rod 5 contracts to drive the placement plate 4 away from the clamping ring 2. During this process, the wire body gradually straightens, and the connection strength between the terminal and the wire body is judged by observing the reading on the dynamometer 6. Whether the connection strength between the terminal and the wire body is within the specified value range.
