Specific implementation mode

It elaborates below in conjunction with the accompanying drawings to the utility model embodiment.

Embodiment 1：As shown in Figures 1 to 6, a kind of locking mechanism of underwater electrical connector, electric connector include mainly inserting First 1 and socket 2, plug 1 is equipped with contact pin 11, and socket 2 is equipped with jack 21, and contact pin 11 plugs together in jack 21, can also pass through Jack 21 is set on plug 1, and the mode of contact pin 11 is set on socket 2 to realize plugging together between plug 1 and socket 2, i.e. plug 1 With the interchangeable setting of structure of socket 2, the terminals that can make to be electrically connected are all had in plug 1 and socket 2, terminals connect with cable It connects, after ensureing that plug 1 and socket 2 plug together, the connectivity of the electricity of electric connector ensures electric connector making in use Use performance.

Existing plug 1 easily loosens after being plugged together with socket 2, causes the terminals being arranged in plug 1 and socket 2 indirectly It is tactile bad, great inconvenience is brought to the use of electric connector, this implementation above-mentioned in the prior art in order to solve the problems, such as Plug 1 in example is realized by locking mechanism after being plugged together with socket 2 and is locked, and ensures that plug 1 and the structure of 2 junction of socket are strong Degree, avoids falling off in use, adversely affect.

Locking mechanism includes the locking slot 3 formed on plug 1 and the elastic drag rope 4 being fixedly connected on socket 2, the locking When structure is in locking state, the tension of drawstring 4 is embedded in locking slot 3, and locking slot 3 can be opened up on plug 1, also can be in socket Locking slot 3 is formed on 2, and drawstring 4 is set on plug 1, realizes the exchange of structure, can equally realize between plug 1 and socket 2 Lock this goal of the invention.

Drawstring 4 is made of elastic material, can be formed with 2 integrated vulcanizing of socket, ensures the knot of drawstring 4 and 2 junction of socket Structure intensity ensures that the service life of drawstring 4 by the tensile force of drawstring 4, drawstring 4 is buckled and is pulled in locking slot in use In 3, this kind of embodiment is smaller to space requirement, simple in structure, is conveniently operated, and takes less, facilitates staff under water Plug 1 or socket 2 are overhauled or replaced, operation difficulty is reduced.

In order to ensure the service life of drawstring 4, the wear intensity of drawstring 4 in use is reduced, locking slot 3 is located at and is inserted It is shaped to arc at first 1 surface, if squarely is arranged in locking slot 3, drawstring 4 is easily that right-angle side rubs with locking slot 3 It wipes, damages, easily reduce the service life of drawstring 4, therefore, camber is arranged in locking slot 3 and 4 contact position of drawstring.

As shown in figure 4, in order to ensure drawstring 4 in cinching process, the balance of plug 1 and socket 2, the setting of drawstring 4 is being inserted The center of seat 2.

As shown in figure 3, locking slot 3 extends to form irregular fluting from 1 surface of above-mentioned plug to 1 central interior of plug, draw Rope 4 is in use it is possible that the phenomenon that being slid from arc locking slot, is influenced by 4 screen resilience of drawstring, easily caused Socket 2 is detached with 1 inserting position of plug, therefore, locking slot 3 is extended to 1 center of plug, if purpose is exactly for drawstring 4 It falls off from arc locking slot, drawstring 4 can be made to enter directly into the locking slot of 1 center position of plug, be unlikely to cause to insert First 1 detaches with 2 inserting position of socket.

The part of contact pin 11 be coated with contact pin sealing ring 12 made of 1 integrated vulcanizing of plug, the end of contact pin 11 is outer The contact of dew, 21 inner wall of jack are coated with and jack sealing ring 22, the processing side of integrated vulcanizing made of 2 integrated vulcanizing of socket Formula can effectively ensure that the structural strength and performance of plug 1, the electric connector usually use under water, the shape of integrated vulcanizing Water can also be effectively avoided to enter from junction the use of 1 internal influence plug 1 of plug at mode.

Contact pin sealing ring 12 can be made with jack sealing ring of rubber material, and elasticity is big, and plug 1 can be effectively ensured and insert The leakproofness of 2 inserting positions of seat.

When plug 1 and 2 grafting of socket, the rubber bore portion elasticity interference of rubber-coated male portion and jack is matched It closes, realizes isolation sealing of the contact between, between contact pair and seawater, metal contact part and the jack 21 of contact pin 11 Elastic metallic contact body portion contact, realize contact pin 11, jack 21 excellent electric contact.

An antelabium 23 is at least provided on the wall surface that jack 21 is contacted with contact pin 11, being equipped in above-mentioned antelabium 23 can elasticity change The setting of the sealing ring of the ring packing antelabium 23 of shape, sealing ring further ensures the sealing between contact pin 11 and jack 21 Property, and the frictional force of contact pin 11 and 21 junction of jack is enhanced, it avoids caused by electric connector loosens in use Contingency.

Embodiment 2：The present embodiment is distinguished with embodiment 1 and is characterized in that：It is to be arranged to locking mechanism in this implementation The structure type of lock sleeve, the lock sleeve include public set and mother set, and public affairs set can be sleeved on outside plug 1 or socket 2, cover position with public affairs It sets correspondingly, mother set is sleeved on outside socket 2 or plug 1, public affairs are covered and are threadedly coupled between mother set, realize plug 1 and socket 2 Between locking.

Embodiment 3：It is distinguished with above-described embodiment, convertible buckle knot also can be used in the locking mechanism in this implementation Structure is equipped with that is, on socket 2 along the turnover buckle of axis, and fixed edge strip is equipped on plug 1, and fixed edge strip is mutually fitted with buckle Match and installation site is corresponding, when locking state, is connected on fixed edge strip, can equally realize between plug 1 and socket 2 Lock this goal of the invention.
