DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0018] according to Figure 1-4As shown, a wiring harness with a quick-connect function includes a wire group 1, wherein the wire group 1 is composed of a plurality of groups of wires 11, and crimping terminals 2 are installed at both ends of the plurality of groups of wires 11. Joints 3 are installed at both ends of the wire group 1, and plug-in connectors 4 are fixedly installed inside the joints 3. The number of the plug-in connectors 4 is consistent with the number of the wires 11. A connecting portion 41 for connecting to the crimping terminal 2 is provided at one end of the plug-in connector 4 close to the wire group 1, and a pressure cover 5 is provided above the connecting portion 41, and the pressure cover 5 is rotatably installed on the joint 3.

[0019] In the above specific embodiment, when the wire group 1 is installed on the connector 3, the entire wiring harness can be assembled by installing the crimping terminal 2 in the connecting portion 41 and pressing the crimping terminal 2 through the pressure cover 5. If a certain wire 11 fails, it is only necessary to open the pressure cover 5 and remove the faulty wire 11 from the connector 3 and replace it. There is no need to replace the entire wiring harness, which reduces maintenance costs and avoids the situation where the equipment cannot be repaired in time due to lack of spare wiring harnesses, affecting the normal use of the equipment.

[0020] The present embodiment provides a wiring harness with a quick-connect function. When a fault occurs in the wiring harness, the maintenance personnel sequentially insert the probe of the multimeter into the through hole 52 at the top of the gland 5 to detect the wires 11 in turn. When the faulty wire 11 is found, the gland 5 is opened to remove the faulty wire 11 from the connector 3. When a new wire 11 is replaced, the crimping terminal 2 is installed on the connecting portion 41, the crimping terminal 2 is squeezed by the first arc-shaped piece 42, and then the gland 5 is closed to align the second arc-shaped piece 43 with the pressing plate 53. The crimping terminal 2 is squeezed to improve the stability of the crimping terminal 2 in the connecting portion 41, and the clamping claw 21 is blocked by the pressing plate 53 to prevent the wire 11 from falling off the connector 3. At the same time, the clamping groove 51 is clamped on the clamping platform 31 to prevent the gland 5 from automatically opening during use. Therefore, when the wiring harness fails, only the faulty wire 11 needs to be replaced, and the entire wiring harness does not need to be replaced, which reduces the maintenance cost and avoids the situation that the equipment cannot be repaired in time due to the lack of spare wiring harness, which affects the normal use of the equipment. The specific technical solution is as follows:

[0021] The inner walls on the left and right sides of the pressure cover 5 are provided with clamping grooves 51, and the connector 3 is provided with a clamping platform 31 corresponding to the clamping grooves 51. When the pressure cover 5 is closed and presses the crimping terminal 2, the clamping grooves 51 are clamped on the clamping platform 31 to prevent the pressure cover 5 from automatically opening during use. A plurality of groups of through holes 52 are provided on the top of the pressure cover 5, and the positions of the plurality of groups of through holes 52 correspond to the plug-in connector 4. The maintenance personnel can insert the probe of the multimeter into the through hole 52 to contact the crimping terminal 2, so as to facilitate the maintenance personnel to detect the wire 11. A pressing plate 53 for pressing the crimping terminal 2 is provided on the bottom wall of the pressure cover 5.

[0022] A claw 21 is provided on the top wall of the crimping terminal 2, and one end of the claw 21 close to the pressure plate 53 is upwardly tilted. When the pressure cover 5 is closed, the pressure plate 53 is located at the rear side of the claw 21, and the pressure plate 53 blocks the claw 21 to prevent the wire 11 from falling off the connector 3.

[0023] First arc-shaped pieces 42 are fixedly mounted on both side walls of the connection portion 41 . When the crimping terminal 2 is installed in the connection portion 41 , the first arc-shaped pieces 42 are pressed and deformed, thereby squeezing the crimping terminal 2 from both sides to prevent the crimping terminal 2 from falling out of the connection portion 41 .

[0024] A second arc-shaped piece 43 is fixedly mounted on the bottom wall of the connecting portion 41. When the pressing cover 5 is closed, the pressing plate 53 presses on the crimping terminal 2, and the second arc-shaped piece 43 is pressed and deformed. The crimping terminal 2 is squeezed by the second arc-shaped piece 43 and the pressing plate 53, thereby improving the stability of the crimping terminal 2 in the connecting portion 41.

[0025] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
