Referring to fig. 3, the female plug 1 includes a female plug housing 11, a male pin 10 is provided in the female plug 1, the number and the position of the male pin 10 are four, the female pin 20 is matched with four, a latch 15 is provided at a position of the female plug housing 11 near the front end thereof, specifically, a latch mounting seat 13 is fixedly provided at a position of the female plug housing 11 near the front end thereof, the latch mounting seat 13 has a mounting cavity, the latch 15 is mounted in the mounting cavity of the latch mounting seat 13 through a compression spring 14, so as to form an elastic latch structure, and the latch 15 has four positions corresponding to the number and the position of the slider 26. Referring to fig. 15-16, the latch 15 is a generally one-piece structure having a first guiding slope 153 at a free end thereof, which is inclined generally from front to back, for guiding the latch 15 to be latched into the latch hole 262; a second guide slope 151 inclined forward from the rear for being unlocked by the second slope 235 of the unlocking ring 23; and a third guide slope 152 formed at the rear end of the first guide slope 153 in substantially the same inclination direction as the second guide slope 153, for being unlocked by the first slope 234 of the unlocking ring 23.
Referring to fig. 17, in the process of inserting and butting the male pin and the female pin, the male pin 10 and the guide hole 211 are gradually close to each other, then the convex surface at the front end of the male pin 10 is in contact with the concave surface at the front end of the insulating sealing rod 25, and since the male pin and the insulating sealing rod are spherical surfaces which are matched with each other, in the process of inserting the male pin 10, a medium such as liquid or gas in the concave surface on the insulating sealing rod 25 is gradually squeezed out from the bottom end of the concave surface to the foremost end, so that the male pin 10 and the insulating sealing rod 25 are sealed and no. With the male plug 2 inserted, the latch 15 also falls into the latch hole 262 of the slider 26, forming a resilient latch mechanism. Continuing to insert, as shown in fig. 18, the male pin 10 is finally inserted into the female pin jack 201, and contacts with the contacts of the female pin 20 to realize electrical connection. In the whole process of inserting the male pin 10 into the female pin 20, due to the existence of the insulating sealing rod 25, the insertion hole of the female pin 20 is always sealed, and no gap exists among the male pin 10, the insulating sealing rod 25 and the insertion hole 300. In addition, referring to fig. 19, the male pin 10 includes a metal part 101 at a front section and a plastic part 102 at a rear section, the plastic part 102 wraps plastic on the rear section of the male pin 10, when the male pin 10 is inserted into the female pin 20, the plastic part 102 replaces the male pin 10 made of original metal material to be in contact with the convex ring 212 in front of the female pin jack 201, compared with the case where hard metal material is in contact with flexible plastic material, the plastic material which is an elastomer is in contact with the convex ring 212 at the rear of the female pin jack 201, the sealing performance is further improved, and the front section 253 of the insulating sealing rod 25 replaces the rear section 252 to be in contact with the convex ring 212 at the rear of the female pin jack 201 (the surface of the insulating sealing rod 25 is also made of encapsulated flexible material) because the insulating sealing rod 25 is pushed backwards, so as to further enhance the front and rear sealing of the contact point where the female pin.
In this embodiment, on the basis of ensuring the front and rear sealing performance of the female pin jack 201, the encapsulant 21 forms a chamber (the first sliding groove 222+ the receding groove 213) communicating with the outside at the rear end of the insertion hole 300, and the rear end of the insulating sealing rod 25 is located in the sliding chamber, so that the front and rear of the female pin jack 201 keep pressure balance with the outside, thereby ensuring that the internal and external pressure difference of the insertion hole 300 is consistent, and facilitating the smooth front and rear movement of the insulating sealing rod in the hole. Under the condition of high pressure (such as deep water environment), the problem that the plugging and unplugging are difficult due to overlarge pressure difference can be avoided.
During the insertion process, the male needle 10 pushes the insulating sealing rod 25 to replace part of the insulating sealing rod 25 to contact with the female needle 20, because the male pin 10 pushes the insulating sealing rod 25 in the inserting process, the contact ends of the male pin 10 and the insulating sealing rod 25 are always tightly matched, the sealing performance of the connection is easy to realize, but when the male pin and the female pin are inserted and pulled out, since the male pin 10 no longer has a pushing force against the insulating seal rod 25, a driving force is required to form a restoring force against the insulating seal rod 25, so that the insulating seal rod 25 and the male pin 10 are kept in close contact, in this embodiment, the rear end of the insulating seal rod 25 is linked with the slider 26, and proposes to make the female plug 1 and the sliding block 26 form a coupling connection relationship, and the pulling-out motion of the female plug 1 and the male plug 2 drives the sliding block 26 and the insulating sealing rod 25 to move synchronously, so as to achieve the tight contact between the insulating sealing rod 25 and the male pin 10 when the male plug and the female plug are pulled out. The coupling connection relationship is realized by a coupling matching mechanism, in this embodiment, a mechanical elastic clamping mechanism is preferably adopted to ensure good reliability in a special environment, and in other embodiments, other coupling forms of the female plug 1 and the slider 26, such as a magnetic attraction connection, may also be adopted. Referring to fig. 17-18, it can be seen from the above description that in the process of inserting the male pin 10 into the pin hole, the latch 15 on the female plug housing 11 also falls into the latch hole 262 on the slider 26 to form an elastic latch mechanism, and along with the insertion of the male pin 10 in place, the slider 26 also slides to the rear end of the first sliding slot 222 and is limited by the rear end of the first sliding slot 222; when the male pin 10 is pulled out from the female pin 20 (the male pin 2 and the female pin 1 move relatively far away), since the fixture block 15 on the female pin housing 11 is clamped in the clamping hole 262 of the slider 26, in the process that the male pin 2 moves relatively far away from the female pin 1, the fixture block 15 abuts against the front end of the clamping hole 262 and drives the slider 26 and the insulating sealing rod 25 to move towards the front end of the male pin 2, the male pin 10 and the insulating sealing rod 25 synchronously move towards the front of the male pin 2 (or the rear of the female pin 1), the convex surface of the front end of the male pin 10 still keeps close fit with the concave surface of the front end of the insulating sealing rod 25, and finally the insulating sealing rod 25 resets to the initial position and forms a sealing structure with the convex ring 212 in front and back of the female pin jack 201.
Referring to fig. 3, in order to further improve the good contact between the male pin 10 and the female pin 20, a pressing elastic sheet 27 is further disposed at the front end of the periphery of the rubber-covered body 21 at a position corresponding to the female pin insertion hole 201, the pressing elastic sheet 27 is an elastic member, and the pressing elastic sheet 27 extends approximately from front to back to be in a sheet shape and slightly tilts at the rear end.
