Description

Technical Field

[0001] The utility model relates to the field of tensile strength testing, in particular to a vehicle cable tie testing fixture. Background Art

[0002] Cable ties, also known as cable ties, are generally made of plastic. They are acid-resistant, corrosion-resistant, have excellent insulation properties, are not susceptible to aging, and have strong endurance. These properties make them a safe, non-toxic, lightweight, and practical bundling tool, widely used in electronics factories, securing oil pipelines for mechanical equipment, securing cables on ships, and securing automotive wiring. Cable ties used for automotive wiring often have a hanging structure on the head to facilitate securing the vehicle structure after securing the vehicle wiring harness, enhancing the overall appearance of the vehicle. The tensile strength of the hanging structure is also a key performance indicator. If the tensile strength is weak and the corresponding part is prone to breakage, the cable tie is of poor quality. Higher tensile strength indicates better quality. The hanging structure of automotive cable ties requires testing of tensile strength data in two directions when clamped. Existing clamps on the market are not capable of testing automotive cable ties or are unable to test for forces in two directions. Utility Model Content

[0019] Reference Figures 1 to 6 The embodiments of the present invention are further described.

[0020] As shown in the figure, the vehicle cable tie test fixture in the embodiment of the present invention includes an upper seat 1, a lower seat 2 and a fixing member. The fixing member is connected to the lower seat 2, and the fixing member and the lower seat 2 have two connection position relationships. A connector 3 for the cable tie is provided on the fixing member. The upper seat 1 drives the cable tie to move and in the two connection position relationships, the upper seat 1 has the same movement direction and pulls the cable tie 9 in the direction away from the lower seat 2 to move. When testing the connection strength of the connector 3 and the cable tie 9, the connector 3 is fixed on the fixing member and the cable tie 9 is fixedly connected to the upper seat 1. The test is carried out by controlling the upper seat 1 to move away from the lower seat 2. Since there are two connection position relationships between the fixing member and the lower seat 2, the force direction between the cable tie 9 and the connector 3 during the test can be changed by adjusting the direction of the fixing member during the test; the test fixture in the present invention can adapt to the tensile performance test of the connector and the cable tie 9 in two different directions, so as to facilitate the detection of the production quality of vehicle cable ties. The detection fixture is easy to operate and has a low manufacturing cost and good practicality.

[0021] Reference Attachment Figure 1 and Figure 2As shown, the fixing member includes a fixed bin 4 and a fixed bin seat 41 fixed to each other, and the fixed bin 4 and the fixed bin seat 41 are fixedly connected by bolts, welding or integral molding. The fixed bin 4 and the fixed bin seat 41 are L-shaped, and a first adjustment block 42 is provided on the lower seat 2. The lower seat 2 is also recessed to form a card slot. The first adjustment block 42 slides laterally and is inserted into the card slot. The first adjustment block 42 is formed with a fixed slot. The fixed slot is provided on the side of the first adjustment block 42 facing away from the lower seat 2 and on the side wall of the fixed slot. A screw hole is provided, in which a locking screw is threaded. A first sliding protrusion 43 cooperating with the fixed slide groove is provided on the fixed bin 4 and the fixed bin seat 41 respectively. The first sliding protrusion 43 slides in the fixed slide groove and is locked by the locking screw. The first sliding protrusion 43 on the fixed bin 4 and the first sliding protrusion 43 on the fixed bin seat 41 are arranged vertically. When different first sliding protrusions 43 are matched with the fixed slide groove, the connectors are in different directions, thereby adapting to the tensile performance test of the connector 3 and the cable tie 9 in two different directions.

[0022] The first adjustment block 42 on one of the fixed bin 4 and the fixed bin seat 41 can cooperate with the lower seat 2 to perform force tests on the cable tie 9 in two directions respectively, and the fixed bin 4 and the fixed bin seat 41 are both connected to the first adjustment block 42 by sliding and locking screws, which is reliable and easy to disassemble and assemble.

[0023] Reference Attachment Figure 6 The fixing chamber 4 is provided with a positioning groove 44, and the connector 3 is arranged in the positioning groove 44. The fixing chamber 4 is rotated to be provided with a fixing chamber cover 5 that closes the port on one side of the positioning groove 44, and the fixing chamber seat 41 closes the other end of the positioning groove. The connector 3 is installed into the positioning groove 44 from the port at one end of the fixing chamber cover 5, and then the fixing chamber cover 5 is rotated and pressed against one end of the connector 3, and the other end of the connector 3 is against the fixing chamber seat 41, so that the connector 3 is reliably positioned in the positioning groove 44. The fixing chamber 4 is provided with a chamber cover lock 51 for locking the fixing chamber cover 5. The chamber cover lock 51 includes a lock buckle, and the fixing chamber cover 5 protrudes with a locking protrusion that cooperates with the chamber cover lock 51. After the fixing chamber cover 5 is closed, the lock buckle and the locking protrusion cooperate to lock it, so as to ensure that the fixing chamber cover 5 is close to the connector, so that the connector 3 will not move during detection and affect the detection result. The structure is practical and convenient for installation and removal of the connector 3.

[0024] A snap-fitting end 52 for mating with the connector 3 is protruded from the fixed compartment seat 41, and the snap-fitting end 52 is suitable for forming a snap-fitting fit with the opening at the corresponding end of the connector 3. A first sliding groove 53 is provided in the positioning groove 44.
