Description
Technical field
The present invention relates to rectangular connector and its plug.
Background technology
Rectangular connector and cylindrical connector are two kinds of common connector forms, higher for some reliability requirements
Occasion, needs to keep locking after connection is plugged together, this locking generally relies on plug as the plug and socket of connector assembly
The locking mechanism set between housing and Socket casing is realized.A kind of locking mechanism such as application publication number that cylindrical connector is used
The locking ball type locking mechanism being disclosed in for the A of CN 106299871 Chinese patent, the front end of Socket casing is provided with adapter sleeve
Be provided with cylinder, the sleeve wall of female connector cylinder be provided with the mounting hole of insertion, mounting hole can radial floating ball, mounting hole
Aperture is provided with the closing-in structure for being used for preventing that ball from deviating from；It is oriented to and moves along the longitudinal direction on the plug casing being adapted to Socket casing
It is dynamic to be equipped with locking sleeve, spring, the periphery of plug casing are provided with the spaced radial between locking sleeve and plug casing
It is provided with for the locked groove with ball engagement.The engagement process of plug and socket is：When both are to inserting, first retract locking backward
Sleeve, mobile link sleeve, after lock ball is moved at locked groove position, unclamps locking sleeve, locking sleeve is in spring further along
Effect is lower to be resetted, and the internal perisporium of locking sleeve presses to lock ball, makes the mated condition being held in locked groove that lock ball is firm, realizes
The locking of two connectors.When needing the separation of two connectors, locking sleeve of pulling back, because lock ball is no longer locked sleeve limit
Position, therefore lock ball can deviate from locked groove and realize unblock.During plugging together, separating, locking sleeve is and plug casing
Outer peripheral face, which coordinates, realizes front and rear guiding, and lock ball and locked groove usually are circumferentially evenly arranged that locking sleeve is better achieved
Good guidance, while spring is circular, using the teaching of the invention it is possible to provide uniform support in itself, can equally aid in realizing guiding.
But, the cross section of rectangular connector is rectangle, and its housing part using non-rotating processing mode because making housing
Part is diametrically（On axially vertical direction i.e. with rectangular connector）It is asymmetric, generally rectangular connector with
The corresponding width size in long side of rectangle is the number of the thickness direction size corresponding with the short side of rectangle of rectangular connector
Times, so if still using the locking ball type locking mechanism on existing cylindrical connector, lock ball will be unable to be evenly arranged, it is difficult to rise
The effect being oriented to auxiliary, and if using the Rectangular Spring with the cross-section adaptation of rectangular connector, spring also can not be right
Locking sleeve provides uniform, smoothly support, and lock sleeve is easily tilted, and imbalance easily occur in particularly width both sides.
If locking sleeve is tilted when using, not only easy clamping stagnation, it is impossible to ensure locking in place, it is also possible to and then cause contact
Tilt, the connector that some needs are accurately interconnected（Such as joints of optical fibre）Cause damage, so existing circular connection
Ripe locking mode can not be applied on rectangular connector on device.
At present, locking mechanism relatively common in rectangular connector mainly has：Single screw as shown in Figure 1 is locked, such as
Double bolts shown in Fig. 2 are locked, clip as shown in Figure 3 is locked etc..Single screw locking mechanism is usually in rectangular connector
Between a design one clamping screw 103 and locking nut 104, plug is realized by screwing for clamping screw and locking nut
101 and the locking of socket 102；Double bolt locking mechanisms are usually that two pairs of clamping screws are separately designed on rectangular connector both sides
103 and locking nut 104, realize the He of plug 101 by screwing the clamping screw and locking nut on connector both sides when using
The locking of socket 102.Above-mentioned clamping screw and locking nut can also replace with the form that screw and screwed hole coordinate.Clip is locked
Locking structure is usually that two controllable locking folders 105 are respectively articulated with the both sides of plug 101, and is separately designed on the both sides of socket 102
Ear 106 is locked, when plug and socket interconnect, pin tail is promoted, two of plug both sides locking folder meetings are with plug along socket
Housing advances, when the leading section for pressing from both sides plug-locking across locking ear and under the effect of torsion spring 107 is pressed from both sides in locking and is locked on socket
Ear step is fastened, and then realizes the locking of plug and socket；When needing to carry out plug and socket unloading, locked with hand pressing plug
Grip rearward end, locking, which is clipped under leverage, completes locking ear separation on leading section and socket, can be by by pulling motion
Plug is extracted from socket, realizes being kept completely separate for plug and socket.
In scheme shown in existing Fig. 1 and Fig. 2, the plug and socket of rectangular connector is locked using screw bolt and nut
Connection, although this locking mode is reliable, screw thread, which is tightened, needs the long time, along with needing to use screwdriver, six
The instruments such as square head wrench, therefore, operating space are required than larger.In addition, scheme shown in Fig. 1 is held because being locked only with a bolt
Easily there is plug and socket connection uneven；In scheme shown in Fig. 2 final plug is solved on both sides using two bolt lockings
Imbalance problem is connected with socket, but is tightened in both sides bolt under out of step conditions, may in plug and socket connection procedure
There is interconnection to tilt, this connector for accurately interconnecting some needs（Such as：Joints of optical fibre etc.）Equally it is harmful.And
In existing clip locking scheme, although solve the problems such as bolt locking uses instrument, the Connection Time is long, but bring
New puzzlement, for example：1st, operating space is larger：Clip locking needs the locking for pressing rectangular connector long edge position with hand to press from both sides come real
The unblock and separation of existing plug and socket are, it is necessary to take bigger connector operating space.2nd, there is hidden danger in connection：Work as device side
When installing multiple rectangular connectors on plate, because the connector operating space is big and locking folder is without any protection, in unloading one
The locking of other connectors may be influenceed during connector, so as to cause to connect reliable hidden danger.3rd, ambient influnence is reliable：The connection
The torsion spring at device locking folder rear portion is in naked state, easily by environmental factor（Such as：Salt fog）Infringement, once spring becomes rusty
The problems such as erosion, it is likely to result in connector and is reliably connected hidden danger.
