[0002] An engine is a machine that can convert other forms of energy into mechanical energy. When the engine runs, it is necessary to conductively connect the engine wiring harness with a connector. Since the engine will generate certain vibrations during operation, the wiring harness is prone to looseness in a vibrating environment for a long time, so an anti-seismic connector is required.

[0003] In the prior art, the patent document with the publication number CN211700582U discloses a bent engine wiring harness connector. The injection molded body includes an injection molded main body and an injection molded sub-body connected at one end. The middle of the wire pressing terminal is bent and the included angle is 30° to 150°. A plurality of wire pressing terminals are sequentially fixed in the injection molded body and both ends are respectively located in the injection molded main body and the injection molded sub-body. A plurality of wire bodies respectively pass through the other ends of the injection molded main body or the injection molded sub-body and are fixed to the wire pressing terminals. By fixing the wire pressing terminals to the upper and lower wire bodies respectively, and then cooperating with the injection molded body to completely wrap the one end of the wire body and the wire pressing terminal, it blocks the engine oil and avoids air leakage and oil leakage phenomena, thereby solving the sealing performance during engine assembly and ensuring the stable working state of the engine; by bending the wire pressing terminals and using the limiting main body and the limiting sub-body to wrap from both ends, the wiring harness connector is in a bent shape, which is convenient for use in different occasions.

[0004] However, the anti-seismic effect of the engine wiring harness connector in the prior art patent CN211700582U is poor, the connection firmness is low, it is not convenient to meet people's use requirements, the wiring harness is prone to looseness in a vibrating environment for a long time, and the practicability is reduced.

[0024] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: an anti-seismic connector for an engine wiring harness, including a main body mechanism 1 and a reinforcement mechanism 2. The reinforcement mechanism 2 is located at the inner end of the main body mechanism 1. The main body mechanism 1 includes a connector body 101, a connection slot 102 and a connector head 103. The connection slot 102 is fixedly arranged at the front end of the connector body 101, and the connector head 103 is movably installed at the inner end of the connection slot 102;

[0025] The main body mechanism 1 further includes a wire harness body 104, a positioning groove 105, a first mounting groove 106, a telescopic rod 107, a return spring 108 and a positioning block 109. The wire harness body 104 is fixedly installed at the rear end of the connector 103. The positioning groove 105 is fixedly arranged at the front end of the upper end of the connector 103. The first mounting groove 106 is fixedly arranged at the upper end of the inner end of the connector body 101. The telescopic rod 107 is fixedly installed at the inner end of the first mounting groove 106. The return spring 108 is movably installed at the outer end of the telescopic rod 107. The positioning block 109 is fixedly installed at the lower end of the telescopic rod 107. The positioning block 109 is adapted to the positioning groove 105. When the connector 103 is inserted, it exerts a squeezing force on the positioning block 109 and the telescopic rod 107 into the first mounting groove 106. When inserted into the specified position, the positioning groove 105 is exactly located below the positioning block 109, the squeezing force disappears, and the return spring 108 drives the telescopic rod 107 and the positioning block 109 to return to their original positions and snap into the positioning groove 105, improving the firmness of the connection between the wire harness and the connector and reducing the influence on the wire harness during engine operation.

[0026] The reinforcement mechanism 2 includes a groove 201, a second mounting groove 202, a bidirectional lead screw 203, a plum blossom knob 204, a positioning nut 205, a fixing block 206, a clamping block 207 and a clamping groove 208. The groove 201 is fixedly arranged at the left and right ends of the inner end of the connector body 101. The second mounting groove 202 is fixedly arranged at the lower end of the inner end of the connector body 101. The bidirectional lead screw 203 is movably installed at the inner end of the second mounting groove 202. The bidirectional lead screw 203 extends to the inner end of the groove 201. The plum blossom knob 204 is movably installed at the lower end of the left end of the connector body 101. The plum blossom knob 204 extends into the interior of the groove 201. The plum blossom knob 204 is fixedly connected to the bidirectional lead screw 203. The positioning nuts 205 are threadedly installed at the left and right ends of the outer end of the bidirectional lead screw 203. The fixing blocks 206 are fixedly installed at the upper ends of the positioning nuts 205. The clamping blocks 207 are fixedly installed in the middle of the fixing blocks 206. The clamping grooves 208 are fixedly arranged at the left and right ends of the connector 103. The clamping grooves 208 are movably connected to the clamping blocks 207. The bidirectional lead screw 203 drives the positioning nuts 205 at both ends to move towards the middle simultaneously. The positioning nuts 205 drive the fixing blocks 206 and the clamping blocks 207 to move to both sides of the connector 103. The fixing blocks 206 can play a role in clamping and fixing both sides of the connector 103. The clamping blocks 207 snap into the clamping grooves 208, further improving the firmness of the connection between the wire harness and the connector and avoiding the problem of wire harness loosening.

[0027] Working principle: First, when using the anti-seismic connector of the engine wiring harness, the operator inserts the connector head 103 into the connection slot 102 inside the connector body 101. When the connector head 103 is inserted, it squeezes the positioning block 109 and the telescopic rod 107 into the first installation groove 106. When it is inserted into the specified position, the positioning groove 105 is exactly below the positioning block 109. The squeezing force disappears, and the return spring 108 drives the telescopic rod 107 and the positioning block 109 to return to their original positions and snap into the positioning groove 105, improving the firmness of the connection between the wiring harness and the connector and reducing the impact on the wiring harness during engine operation. The operator rotates the plum blossom knob 204 to drive the bidirectional lead screw 203 to rotate. The bidirectional lead screw 203 drives the positioning nuts 205 at both ends to move towards the middle at the same time. The positioning nuts 205 drive the fixed blocks 206 and the clamping blocks 207 to move to both sides of the connector head 103. The fixed blocks 206 can clamp and fix both sides of the connector head 103, and the clamping blocks 207 snap into the clamping grooves 208, further improving the firmness of the connection between the wiring harness and the connector and avoiding the problem of the wiring harness loosening.
