Description

Technical Field

[0001] The utility model relates to the technical field of wire harness detection, in particular to a self-clamping mechanism for wire harness detection. Background Art

[0002] The wiring harness plays the role of connecting signals and power between devices. It is a wiring component that connects various electrical devices in circuits such as automobiles. It is composed of insulating sheaths, wiring terminals, wires and insulating wrapping materials. The wiring harness is usually made of metal parts such as copper. After the contact terminals are crimped with the wires, they are plastic-pressed with insulators or metal shells, and tied with cable ties to form components that connect circuits.

[0003] After the contact terminal is crimped with the wire, a tensile force test is required to determine whether the maximum tensile force that causes the contact terminal to fall off the wire is within the design range, thereby ensuring the connection strength between the contact terminal and the wire. The traditional clamping mechanism is cumbersome to operate and cannot achieve rapid detection. In addition, clamping slippage may occur during the detection process. Based on this, a self-clamping mechanism for wire harness detection is proposed that can solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] The liner block 10 has a movable groove 11 , which vertically penetrates the liner block 10 and is open on one side. The upper cover 20 is arranged on the top of the liner block 10 , and two groups of upper guide grooves 21 are opened on the upper cover 20 .

[0029] The movable groove 11 has a receiving function, and one side of the movable groove 11 is open, that is, one side of the movable groove 11 has an opening, and the upper cover 20 covers the upper part of the movable groove 11 on the top of the liner 10 to reduce the entry of external dust and other impurities.

[0030] There are two groups of shifting blocks 30, each group of shifting blocks 30 is movably arranged on the movable groove 11 through the adjustment component 40, and the two groups of shifting blocks 30 can extend along the movable groove 11 to clamp the contact terminal or be retracted into the movable groove 11 to release the contact terminal.

[0031] The inner walls of both sides of the movable groove 11 are provided with first inclined surfaces 111, and the outer walls of the two groups of moving blocks 30 are provided with second inclined surfaces 301. The first inclined surfaces 111 are in contact with the second inclined surfaces 301 in a one-to-one correspondence, and the distance between the two groups of first inclined surfaces 111 gradually decreases from the inside to the outside.

[0032] The second inclined surface 301 on the shift block 30 contacts the adjacent first inclined surface 111. When the two groups of shift blocks 30 are received in the movable groove 11, the interval is enlarged to loosen the contact terminal. When the two groups of shift blocks 30 are extended out of the movable groove 11, the interval is reduced to clamp the contact terminal.

[0033] The adjustment assembly 40 includes a straight rod 41 and a spring 42 . The straight rod 41 extends vertically upward and passes through a group of upper guide grooves 21 . The spring 42 is connected to the movable groove 11 . Each group of upper guide grooves 21 is parallel to the adjacent first inclined surface 111 .

[0034] When inspecting the wiring harness, the pad 10 is fixed to the carrier, and the two groups of straight rods 41 are pushed inward along the upper guide groove 21 above the upper cover 20, so that the two groups of shift blocks 30 are retracted into the movable groove 11 to compress the spring 42 and expand the interval, and then the contact terminal is inserted into the expanded interval, and then the push on the two groups of straight rods 41 is cancelled. The two groups of shift blocks 30 are partially extended out of the movable groove 11 under the elastic force of the spring 42. As a result, the interval between the two groups of shift blocks 30 is reduced to clamp the inserted contact terminal. The operation is simple and convenient, the operation time for clamping the contact terminal is short, and the wiring harness is quickly inspected.

[0035] A plurality of anti-slip protruding teeth 302 are disposed on the adjacent side of the two groups of shifting blocks 30 .

[0036] During the detection of the wiring harness, the anti-skid convex teeth 302 are provided to improve the clamping effect on the contact terminal and prevent slipping.

[0037] Example 2

[0038] A push handle is provided on the top of the straight rod 41, which is not shown in the figure. The push handle increases the contact surface, making it easier to push the straight rod 41 to move.

[0039] A lower cover 50 is disposed at the bottom of the lining block 10 , and a row of grooves 51 are formed on the lower cover 50 . The upper cover 20 and the lower cover 50 are detachably connected to the lining block 10 via connecting pieces 60 .

[0040] The lower cover 50 covers the bottom of the movable groove 11 at the bottom of the liner 10 to reduce the entry of external impurities such as dust. The connecting piece 60 is preferably a bolt, screw, etc., so that the upper cover 20 and the lower cover 50 can be disassembled for maintenance.

[0041] After the wiring harness is inspected, the contact terminals are separated from the wires, and the two sets of shift blocks 30 are retracted into the movable grooves 11. The clamped contact terminals can automatically fall downward along the row grooves 51 without the need for manual cleaning, further improving the convenience of operation. The separated contact terminals will not remain in the movable grooves 11, i.e., avoiding affecting the clamping of the contact terminals during the next inspection.

[0042] Example 3

[0043] Two groups of lower guide grooves 52 are formed on the lower cover 50 . The two groups of lower guide grooves are horizontally symmetrically distributed with the two groups of upper guide grooves. The straight rods 41 passing through the upper guide grooves extend downward and penetrate into the lower guide grooves.

[0044] That is, the moving block 30 has a guiding effect on the upper and lower ends of the moving airway, and the movement stability is good.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
