Example 2

Fig. 1 and 2 also show embodiment 2 of the present invention, and embodiment 2 differs from embodiment 1 in that: the lateral surface of slope seal section 114 is formed with two at least ridge form sealing washer 1141 that arrange in proper order along its axis direction, ridge form sealing washer 1141's front side inclined plane with be formed with contained angle alpha between the lateral surface of slope seal section 114, ridge form sealing washer 1141's rear side inclined plane with be formed with contained angle beta between the lateral surface of slope seal section 114, wherein, contained angle alpha with contained angle beta is the acute angle, just contained angle beta is greater than contained angle alpha, ridge form sealing washer 1141 is made by elastic material.

A connection point 1142 is formed between the back side inclined surface of the ridge-shaped sealing ring 1141 and the outer side surface of the inclined sealing section 114, when the outer side surface of the inclined sealing section 114 is subjected to radial pressure, for example, in the process of gradually inserting the insertion portion into the annular sealing groove 221, the outer side surface of the inclined sealing section 114 is subjected to radial pressure from the side wall of the annular sealing groove 221, the ridge-shaped sealing ring 1141 can be laid back around the connection point 1142 and attached onto the outer side surface of the inclined sealing section 114, and the shape of the ridge-shaped sealing ring 1141 after being laid down can be filled into the slit between the inclined sealing section 114 and the inclined adapting section 2212 to form a seal, and when the radial pressure of the outer side surface of the inclined sealing section 114 is removed, for example, in the process of gradually withdrawing the insertion portion from the annular sealing groove 221, the radial pressure of the outer side surface of the inclined sealing section 114 gradually decreases until disappears, because ridge sealing washer 1141 is made by elastic material, the ridge sealing washer 1141 after lodging resumes its shape and gesture before receiving the oppression under the effect of its self elastic restoring force, and is formed with the slot that is located between the two adjacent ridge sealing washers 1141, grafting portion progressively follows the in-process that cyclic annular seal groove 221 withdrawed, ridge sealing washer 1141 can be in the same direction as the area and take out residual water stain and spot in cyclic annular seal groove 221, prevents that subsequent butt joint in-process from leading to water proof failure because the residual water stain of cyclic annular seal groove 221 and spot.

Further, the angle of the included angle alpha is 5-20 degrees, and the angle of the included angle beta is 45-85 degrees. In a preferred embodiment, the angle of included angle α is 15 ° and the angle of included angle β is 75 °.

Further, the height of the cross section of the ridge seal 1141 decreases in the direction away from the male interface, and the height of the cross section of the ridge seal 1141 closest to the male interface is assumed to be h₁The ridge-shaped sealing ring 1141 next to the male interface has a cross-sectional height h₂The ridge-shaped sealing ring 1141 third closest to the male interface has a cross-sectional height h₃…, the ridge seal 1141 furthest from the male interface has a cross-sectional height h_nThen, there are: h is_n＝h₁q^n-1Wherein, in the step (A),by adopting the structure, the initial insertion resistance of the insertion part can be reduced, and the rebound acting force of the insertion part when being pulled out is improved, so that the insertion is convenient, and the insertion is difficult to pull out due to good sealing performance when being pulled out.

Example 3

Also shown in fig. 2 is example 3 of the present invention, which example 3 differs from example 1/example 2 in that:

a male wire 122 is arranged inside the male butt joint 11 in an extending manner, and the male wire 122 enters the male buffer space 112 and then is electrically connected with the male conductive cell 121; the male buffer space 112 is provided with a plug-in reset component 13 elastically connected between the male conductive cell 121 and the male butt joint 11. The plug-in reset component 13 can ensure that the male conductive cell 121 and the female conductive cell 222 always keep good contact, and prevent the circuit from being broken due to loosening between the two.

In a preferred embodiment, the male and female connectors 11, 12, 21, 22, the extension 23 and the locking sleeve 243 are made of insulating materials, and the locking and returning member 245 and the inserting and returning member 13 may be any one of a spring, a torsion spring, hydraulic or pneumatic or a combination of two or more of the above elastic returning methods.

The number of apparatuses and the scale of the process described herein are intended to simplify the description of the present invention. Applications, modifications and variations of the present invention will be apparent to those skilled in the art.
