Description

A kind of plug-in connector for electric connection equipped with automatic locking mechanism

Technical field

The present invention relates to a kind of electrical connection connector, especially a kind of plug-in connector for electric connection equipped with automatic locking mechanism.

Background technology

It is typically to be made of two plugs of male and female for the plug-in connector for electric connection for industrial connector.By In such industrial connector sometimes under applied to harsh environmental condition, it is necessary to ensure two housings in strenuous vibration and high load capacity Condition can be locked mutually securely to ensure its higher seal request, be arranged one on male and female plug so generally requiring A or two tight locking buttons, can surround the fulcrum post rotation on male and female housing parts, and locked position be overlapped on it is public, Latch protrusion on parent shell component or locking pin, to realize that male and female shell mutually locks binding.

Traditional lock type connecting structure is that male and female shell is mutually locked in binding procedure, and there is usually require manually This program is completed to operate, and also needs after the completion of checking determining program whether male and female plug mutually bind completely by locking The problem of.

Invention content

The mesh of the present invention is to provide a kind of plug-in connector for electric connection equipped with automatic locking mechanism so that it can avoid existing The defect of technology realizes safe and reliable automatic connection locking.

For achieving the above object, present invention employs following technical solutions：A kind of electricity equipped with automatic locking mechanism Plug connector is connected, is made of male plug, female and the lock handle on male plug；The male plug and female The male and female shell for including the positive and negative electrode connected suitable for grafting and being moulded on the outside of positive and negative electrode；On the male and female shell It is respectively equipped with fulcrum post and locking pin；Described lock handle one end is equipped with grip part, and the other end is two spaced locks The tail end of tight leg, each locking leg is arranged at intervals with a supporting arm and a locking arm.

The supporting arm be equipped with the matched mounting hole of fulcrum post on public shell so that lock handle can It is rotated by axle center of fulcrum post；

In order to enable locking pin to facilitate into that in locking hole and can be fixedly secured, the locking arm end is equipped with one section of guiding Arc, for importing locking pin in the circular arc cavity on locking arm；The locking regiones brachii medialis section is equipped with and the mother The matched circular arc cavity of locking pin on shell.

In order to make the fully automated closure of male and female plug, a briquetting is equipped on parent shell；In operation, for general Female and male plug tight close need to only apply female one downward power, during female declines, on female Briquetting drive supporting arm rotate around fulcrum post, to drive lock handle rotate, when locking pin is completely on locking arm In circular arc cavity, master-slave socket also just completes grafting, and master-slave socket is in closed state.

The beneficial effects of the invention are as follows：（1）The design of briquetting so that when male and female plug is mutually inserted, briquetting drives supporting arm rotation Turn, so that the circular arc cavity on locking arm is mutually locked with locking pin automatically, enable male and female plug auto lock；（2）Locking arm end Pilot arc reduces the friction between locking arm and locking pin so that lock handle is more robust.

Description of the drawings

Fig. 1 is the male and female plug opening state figure of the present invention；

Fig. 2 is the male and female plug closed state figure of the present invention；

Fig. 3 is the stereogram of the lock handle of the present invention；

In figure, 1, male plug；2, female；3, handle is latched；4, fulcrum post；5, locking pin；6, briquetting；31, grip part；32、 Supporting arm；33, locking arm；33-1, circular arc cavity；33-2, pilot arc.

Specific implementation mode

In conjunction with shown in Fig. 1 to Fig. 2, a kind of plug-in connector for electric connection equipped with automatic locking mechanism, by male plug 1, female 2 And the lock handle 3 on male plug 1 forms；The male plug 1 and female 2 include be suitable for that grafting is connected just, Negative electrode and the male and female shell being moulded on the outside of positive and negative electrode；Fulcrum post 4 and locking are respectively equipped on the male and female shell Pin 5.

Fig. 3 therein is the stereogram for latching handle, is made as described below in conjunction with Fig. 3：Described 3 one end of lock handle is equipped with Grip part 31, the other end are two spaced locking legs, and the tail end of each locking leg is arranged at intervals with a supporting arm 32 With a locking arm 33.

The supporting arm 32 be equipped with the 4 matched mounting hole of fulcrum post on public shell so that lock handle Hand 3 can be rotated with fulcrum post 4 for axle center.

In order to enable locking pin to facilitate into that in locking hole and can be fixedly secured, 33 end of locking arm is equipped with one section Pilot arc 33-2, for importing locking pin 5 in the circular arc cavity 33-1 on locking arm 33；The 33 inside section of locking arm It is equipped with and the 5 matched circular arc cavity of locking pin on the parent shell（33-1）.

In order to make the fully automated closure of male and female plug, a briquetting 6 is equipped on parent shell；

Its working principle is that：In use, it to realize the grafting of male and female plug, need to only apply one to female 2 downwards Power F1, female 2 declines under force, and during decline, briquetting 6 on female will drive supporting arm 32 around bearing Pin 4 rotation to latch handle 3 around rotationally support pin 4 counterclockwise rotate, when locking pin 5 by pilot arc 33-2 completely into lock In circular arc cavity 33-1 on tight arm 33, male and female plug also just completes grafting at this time, and male and female plug is in closed state；This When due to locking pin 5 and locking arm 33 close connection, master-slave socket realizes tight closure.

When realizing the separation of male and female plug, only it need to apply a downward power F2, lock in the grip part 31 of lock handle Handle 3 will be rotated clockwise around fulcrum post 4, to which supporting arm 32 touches briquetting 6, briquetting 6 be jacked up upwards, so that lock Tight arm 33 is detached from locking pin 5, so that female 2 is detached from male plug 1, realizes the separation of male and female plug.

The technical concepts and features of above-described embodiment only to illustrate the invention, its object is to allow be familiar with technique Personage cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to this hair Equivalent change or modification made by bright Spirit Essence, then should be covered by the protection scope of the present invention.
