Problems solved by technology

A conventional sealing solution is to install a sealing rod in the female needle, and use the male needle to push the sealing rod to move, so that it is gradually inserted into the female needle without gaps until it contacts with the female needle; in conventional technology, the female needle is in the The chamber is usually airtight, and in the environment of deep water and high water pressure, if the internal and external pressures of the closed female pin end and the male pin end are unbalanced when plugging and unplugging, it will be very difficult to plug in and out, so conventional technology will set The oil bladder is used to ensure the pressure balance, but the cost of the oil bladder is extremely high, which is not suitable for large-scale promotion and application, and the various connectors on the market still generally have the problem of poor sealing

Embodiment 1

[0051] refer to figure 1 and image 3 As shown, as a preferred embodiment of the present invention, a connector is provided, including a male plug 2 and a female plug 1 that can be mated together, with several female pins 20 on the male plug 2, and several female pins 20 on the female plug 1. A male pin 10, when the male plug 2 and the female plug 1 are butted together, the male pin 10 can be inserted into the female pin 20, and cooperate with the female pin 20 to complete the electrical connection between the male plug 2 and the female plug 1. Specifically, the male plug 2 includes a male plug housing 22, see Figure 11 and Figure 12 , the male socket housing 22 is a cylindrical structure with a cylindrical inner cavity, and a first sliding groove 222 is opened on its outer peripheral surface, and the first sliding groove 222 communicates with the inner cavity of the male socket housing 22 . refer to Figure 11 and Figure 13 , a package of colloid 21 is fixed inside th...

Embodiment 2

[0066] This embodiment provides a connector whose structure is generally similar to the connector structure in Embodiment 1, the difference is that this embodiment adopts another set of structures on the elastic locking mechanism between the female plug shell 11 and the slider Specifically, in Embodiment 1, the structure of the elastic bayonet (block 15) is arranged on the female socket housing 11, and the bayonet (that is, the hole 262) is arranged on the slider. On the contrary, this The embodiment chooses to set the clamping block structure on the slider, and set the clamping slot on the female plug shell 11. Now, it will be further explained in conjunction with the accompanying drawings:

[0067] refer to Figure 26 and 27 , and in accordance with the description in Embodiment 1, the slider 26' has a claw elastic piece 26'1, which is an elastic member of a sheet structure, which is formed from the base part 26'2 of the slider 26' Extend diagonally. Correspondingly, ther...

Abstract

The invention relates to an electric connection device with good sealing performance and easy plugging, and the device comprises a first connection assembly and a second connection assembly which canbe plugged with each other, wherein the first connection assembly is provided with an insertion rod, the second connection assembly is provided with a plugging hole channel, an insulating sealing rodis movably assembled in the plugging hole channel, and an insertion rod can be inserted into the plugging hole channel and is electrically connected with the plugging hole channel. The rear end of theinsulation sealing rod is arranged in the environment communicated with the outside, good pressure balance inside and outside the female needle is achieved, on the basis of movable sealing of the insulation sealing rod, the sliding block is arranged at the rear end of the insulation sealing rod in a linkage mode, and the coupling matching structure is arranged to enable the sliding block and thefirst connecting assembly to form a linkage relation, thereby achieving the sealing when the male and female plugs are pulled out. In addition, the invention further provides a quick plug module, an unlocking structure and a control mechanism, and underwater manual plugging or ROV (underwater robot) plugging is facilitated.

Description

technical field [0001] The invention relates to an electrical connection device, in particular to an underwater connector with excellent sealing performance, good pressure balance and easy plugging and unplugging. Background technique [0002] Underwater connectors are usually used in special environments such as deep water. For underwater connectors with underwater plugging and unplugging functions, it is necessary to ensure that the male and female plug contacts of the connector are sealed and isolated from the external medium during the plugging and pulling process, so as to avoid cause a short circuit. A conventional sealing solution is to install a sealing rod in the female needle, and use the male needle to push the sealing rod to move, so that it is gradually inserted into the female needle without gaps until it contacts with the female needle; in conventional technology, the female needle is in the The chamber is usually airtight, and in the environment of deep wate...
