As shown in fig. 3 and 5, after the injected glue enters the mold cavity corresponding to the main body 3 from the glue inlet 33, the injected glue flows towards the mold cavity corresponding to the actuating mechanism 4 disposed at the front and rear sides of the main body 3, when the injected glue flows to the mold cavity corresponding to the two connecting portions 42, the injected glue is divided into two injected glue streams, and the two injected glue streams merge at the mold cavity corresponding to the cross beam 411, due to the existence of the adjusting portion 44, the entire space of the mold cavity corresponding to the cross beam 411 does not extend straight, but there are portions with different space sizes, so that the injected glue flows fast at the portion with a larger space, and flows slow at the portion with a smaller space, and due to the asymmetric arrangement of the adjusting portion 44 relative to the center line L extending in the front and rear direction of the cross beam 411, the flow rate of the injected glue towards the middle portions of the two mold cavities corresponding to the cross beam 411 is changed, and finally, the joint line W formed by the merging at the middle portions of the mold cavity corresponding to the cross beam 411 extends in the front and rear direction The curve that stretches sets up, just joint line W is relative central line L offset that crossbeam 411 extends along the fore-and-aft direction is the curve setting like this joint line W makes two strands of injecting glue cooling back formation crab-bolt structures, also the unsmooth cooperation of part that two strands of injecting glue combine, coincide each other.

As shown in fig. 9 and 12, in which the solid line of the actuating mechanism 4 in fig. 12 represents the buckled state, and the dotted line of the actuating mechanism 4 in fig. 12 represents the unbuckled state, it can be seen that when a user's finger applies a pressing force F to the two beams 411 in the front-back direction toward the main body 3, that is, the user's finger applies an opposite pressing force F to the two beams 411, a deformation space is provided for the beams 411 due to the hollow-out groove 43 abutting against the beams 411, and the beams 411 are subjected to the pressing force F and bent toward the main body 3, so that when the beams 411 are deflected toward the main body 3 around the connecting portion 42 as a fulcrum, the portion of the operating portion 41 near the beams 411 with respect to the stopper 34 in the left-right direction is bent toward the main body 3 in the front-back direction, the portion of the operating portion 41, which is away from the cross beam 411 in the left-right direction relative to the stopper 34, is bent and deformed in the front-back direction, and the latching portions 461 at the ends of the latching arms 46 at the left and right ends of the operating portion 41 are driven to tilt toward the side away from the insulating body 11, so as to release the latching between the latching portions 461 and the latching grooves 111 of the insulating body 11, and at this time, the user can upwardly extract the plastic cover 20, so as to finally realize the separation between the plastic cover 20 and the insulating body 11. The two stoppers 34 on the front side or the rear side of the main body 3 stop the operating portion 41 overlapping with the operating portion in the front-rear direction in a direction away from the main body 3, so as to prevent the operating portion 41 from being excessively deformed and broken. Wherein because the joint line W is the setting of curve and forms the crab-bolt structure along fore-and-aft direction, has strengthened the joint strength of crossbeam 411 department, and be in crossbeam 411 receives along the fore-and-aft direction orientation when the pressing force F of main part 3, because the direction of action of joint line W and pressing force F is not parallel arrangement, just the joint line W forms the intersect with the direction of action of pressing force F, makes operating portion 41 is difficult because of receiving along the fore-and-aft direction orientation the pressing force F of main part 3, and in crossbeam 411 department breaks.

The utility model has the advantages as follows:

1) compared with the prior art, the utility model arranges the adjusting part 44 for changing the wall thickness of the beam 411 in the front-back direction or the up-down direction, and the adjusting part 44 is asymmetrically arranged relative to the central line L of the beam 411 extending in the front-back direction, so that when two strands of glue flow to the beam 411, the flow rates are different at different places with different wall thicknesses, and the bonding line W formed by joining two strands of glue is finally not arranged in a straight line extending in the front-back direction, but arranged in a curved line extending in the front-back direction, compared with the bonding line W arranged in a straight line, the bonding strength of the beam 411 is enhanced, and when the operating part 41 is pressed by the pressing force F towards the main body 3 in the front-back direction, so as to release the buckling between the buckling part 461 and the electric connector component 10, since the curved bonding line W and the pressing force F are not parallel to each other and intersect each other, it is known that the operating portion 41 is not easily broken from the cross beam 411 along the curved bonding line W when the pressing force F is applied.

2) Since the grooves are formed at the cross member 411 to reduce the structural strength of the cross member 411, in order to avoid the reduction of the structural strength of the cross member 411, the reinforcing protrusions 45 are formed on the cross member 411 to compensate for the structural strength reduced by the grooves, so as to avoid the fracture of the operation portion 41 at the cross member 411 due to the pressing force F.

3) The connecting portion 42 includes the first portion 421 extending in the front-back direction and the second portion 422 extending in the up-down direction, and the hollow groove 43 is disposed between the two first portions 421 and the two second portions 422, so as to increase a deformation space of the cross beam 411 when being subjected to an external force.

4) The reinforcing ribs 423 are provided at the connection between the first portion 421 and the second portion 422, so that the second portion 422 is not easily broken at the connection between the first portion 421 and the second portion 422 when receiving a pressing force F transmitted thereto from the cross member 411 in the front-rear direction and directed toward the main body 3.

5) The rough portion 412 is a plurality of protrusions protruding toward a side away from the main body 3 in the front-back direction, and the plurality of protrusions are arranged beyond the left and right sides of the cross beam 411 in the left-right direction, so that friction force of fingers of a user when two operating portions 41 apply a pressing force F toward the main body 3 side is increased.

6) The lower surface of the cross member 411 is higher than the upper surface of the main body 3, so that the cross member 411 does not block the deformation of the cross member 411 toward the main body 3 due to the block of the main body 3 when the cross member 411 receives the pressing force F provided toward the main body 3 in the front-rear direction.

7) The two connecting portions 42 on the front side or the rear side of the main body 3 are located between the two stoppers 34 on the same side in the left-right direction, and are spaced from the two stoppers 34 on the same side, and the two stoppers 34 on the front side or the rear side of the main body 3 are spaced from and partially overlapped with the operating portion 41 on the same side in the front-rear direction, so as to provide a deformation space for the actuating mechanism 4 when receiving a pressing force F toward the main body 3 in the front-rear direction, and when the cross beam 411 receives the pressing force F toward the main body 3 in the front-rear direction, the stoppers 34 on the same side block the overlapping portion of the operating portion 41 in the direction away from the main body 3, so as to prevent the operating portion 41 from being excessively deformed and broken.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all the equivalent technical changes using the description and drawings of the present invention are included in the scope of the present invention.
