Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to an anti-pulling structure of a wire harness and a connector. Background Art

[0002] A wire harness connector is a device that connects two or more wires by connecting one or more wires together. It is mainly used to connect different electrical components and equipment and is widely used in automobiles, electronic equipment, industrial machinery, etc. This solution specifically relates to a wire harness and connector pull-out resistant structure;

It is not convenient to press and fix to provide anti-pullout properties. After being fixed, it is easy to slide if pulled for a long time. It is not convenient to adjust and increase the pull-out buffer length of the wire harness body, which has a certain impact on actual use. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a wire harness and connector anti-pull-out structure includes a connector body 1, a positioning component 2 is movably installed on the front of the connector body 1, a stretching component 3 is installed on the rear of the positioning component 2 and passes through the connector body 1, the positioning component 2 includes a positioning seat 4, a plurality of wire harness grooves 5 are opened inside the positioning seat 4, a top plate 6 is fixedly installed on the top of the positioning seat 4, a plurality of positioning rods 7 are movably installed through the top of the top plate 6, a first knob 8 is fixedly installed on the top of the positioning rod 7, a positioning block 9 is movably installed on the bottom end of the positioning rod 7 and is located in the wire harness groove 5, an arc groove 10 is opened at the bottom of the positioning block 9, and a plurality of ring pads 11 are fixedly provided on the inner wall of the arc groove 10.

[0023] In this embodiment, the front view of the cable trough 5 is rectangular, and a plurality of cable troughs 5 are arranged equidistantly. The wiring harness body is inserted into the cable trough 5 and connected to the connector body 1 for fixing and supporting.

[0024] In this embodiment, the positioning rod 7 passes through the top of the top plate 6 and is threadedly connected. The bottom end of the positioning rod 7 passes through the interior of the positioning block 9 and is connected through a bearing. The threaded connection of the positioning rod 7 drives the positioning block 9 to slide up and down, thereby pressing and fixing the wiring harness body.

[0025] In this embodiment, the positioning block 9 is located in the wiring harness groove 5 and is slidable up and down. The inner wall of the arc groove 10 is arc-shaped. The positioning block 9 is located in the wiring harness groove 5 and slides up and down to press the wiring harness body. The friction force is increased by the annular pad 11 in the arc groove 10 to improve the tensile resistance of the wiring harness body.

[0026] In this embodiment, the stretching assembly 3 includes two screws 12, and screw grooves 13 are opened on both sides of the front part of the connector body 1. Two guide rods 14 are fixedly installed on both sides of the rear part of the positioning seat 4. The screw 12 movably passes through the front and rear parts of the positioning seat 4 on both sides and is located in the two screw grooves 13. A spring 15 is sleeved on the outer periphery of the screw 12 near the front end, and a second knob 16 is fixedly installed at the front end of the screw 12. The distance between the positioning seat 4 and the connector body 1 can be changed by rotating the screw 12, and can be adjusted when the wiring harness body is loose.

[0027] In this embodiment, the screw rod 12 is located in the screw groove 13 and is threadedly connected. The screw rod 12 passes through the interior of the positioning seat 4 and is movably rotatable. The screw rod 12 is extended and retracted under the action of the rotation and thread of the screw rod 12, so that the positioning seat 4 is easily adjusted.

[0028] In this embodiment, the guide rod 14 penetrates the interior of the connector body 1 and is slidably arranged. The two ends of the spring 15 are respectively connected to the rear of the positioning seat 4 and the front of the connector body 1. The spring 15 allows the positioning seat 4 to always slide forward and contact the rear of the second knob 16.

[0029] It should be noted that the utility model is an anti-pullout structure for a wiring harness and a connector. When in use, the wiring harness body is first inserted into the wiring harness groove 5 in sequence and connected to the corresponding position of the connector body 1. When fixing, the first knob 8 is rotated by a tool so that the positioning rod 7 drives the positioning block 9 to slide downward under the action of the thread, and the wiring harness body is pressed and fixed. The friction force is increased by the ring gasket 11. Since the wiring harness body is prone to sliding due to long-term pulling, causing the connection to fall off, when adjusting, the second knob 16 is rotated by using a tool to make the screw 12 rotate and slide inward under the action of the thread, thereby driving the positioning seat 4 to slide backward, so that the wiring harness body located between the positioning seat 4 and the connector body 1 is bent, thereby increasing the pulling buffer length of the wiring harness body.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
