Description
Technical field
The present invention relates to a kind of D-SUB connectors, specifically a kind of D-SUB connectors with protective case.
Background technology
D-SUB sockets and plug are the high performance-price ratio general connector widely applied in industrial equipment, D-SUB connector masters
To include glue core, loaded on the terminal on glue core, the metal shell being wrapped in outside glue core, the plastic casing being placed on outside metal shell
And it is arranged in the fastening screw on plastic casing.
At present, protected although the overall outermost of contact pin of the D-SUB connectors of in the market on D-SUB connectors is set
Protection structure, but in daily placement and in use, center section contact pin easily touches staff, because pin head is sharp,
Unnecessary injury can be caused.Due to the use of etc. reason, the material that there is a part of contact pin is softer, can be by during improper use
Contact pin bending, so as to cause whole D-SUB connectors not use normally.
In order to solve the above problems, prior art proposes a kind of D-SUB connectors with contact pin protection structure, and it is led
Structure is wanted to include glue core, loaded on the terminal on glue core and the shell being wrapped in outside glue core.The shell include plug casing and
Socket casing, be provided with the plug casing on some contact pins, the every contact pin be arranged with for avoid contact pin bending by
The protection structure of damage.The protection structure includes expansion link, and the contact pin is located on the inside of expansion link, and described expansion link one end is with inserting
Casing bottom is connected, and spring is provided with expansion link, and the spring is fixed on expansion link inwall.
Above-mentioned prior art has the drawback that：It is complicated, it is difficult to implement；After imprudence have compressed expansion link, still
So there is potential safety hazard.
The content of the invention
It is an object of the invention to provide a kind of D-SUB connectors with protective case, to solve prior art presence
It is complicated, it is difficult to implement, the problem of there is potential safety hazard.
To achieve the above object, the invention provides following technical scheme：A kind of D-SUB connectors with protective case,
Including glue core, loaded on the terminal on glue core and the shell being wrapped in outside glue core, the shell includes plug casing and socket shell
Body, plug casing is connected with each other with Socket casing by screw bolt and nut；Some contact pins are provided with the plug casing, at this
Socket casing is provided with jack corresponding with the contact pin, it is characterised in that outside the one end of described plug casing provided with contact pin
Enclose provided with the ring protection set by whole contact pins set internally, the two ends that the ring protection covers are consolidated with one end of a screw rod respectively
Fixed connection；Rotate one driven gear of connection respectively at the two ends of described plug casing, spiral shell is provided with the axle center of the driven gear
Hole, the other end of the screw rod is threaded through the screw in the driven gear axle center；It is arranged below in the nut of the bolt integral
Driving gear, and be intermeshed with described driven gear.
The top covered in the ring protection is provided with top cover, and through hole corresponding with described contact pin is provided with the top cover.
It is an advantage of the invention that：In plug end there is provided whole contact pins are covered into protective case internally, and with bolt tooth
Wheel drive connection, in use, protective case top is higher than the top of contact pin, and protective case will not be disappeared by compression movement
Except potential safety hazard；When mounted, bolt drives screw rod to move up by gear drive, and contact pin extends downwardly from protective case, no
Influence is normally used.

Embodiment
As shown in figure 3, a kind of D-SUB connectors with protective case of the present invention, including glue core, loaded on the terminal on glue core
With the shell being wrapped in outside glue core, the shell includes plug casing 1 and Socket casing 2, plug casing 1 and Socket casing 2
Pass through bolt 4 and nut（Top is provided with the cylinder of screw）8 are connected with each other；In the plug casing 1（Lower end）Provided with some
Contact pin 6, is provided with jack 5 corresponding with the contact pin, it is characterised in that be provided with described plug casing 1 on the Socket casing 2
One end periphery of contact pin 6 is provided with the ring protection set 14 by whole 6 sets of contact pins internally, and the ring protection covers 14 upper ends（It is left
It is right）Lower end of the two ends respectively with a screw rod 11 is fixedly connected；Rotated respectively at the two ends of described plug casing 1 connection one from
Moving gear 12, is provided with screw, the upper end of the screw rod 11 is threaded through the axle center of driven gear 12 in the axle center of the driven gear 12
Screw；Integral driving gear 13 is arranged below in the nut of described bolt 4, and is mutually nibbled with described driven gear 12
Close.
14 top is covered in the ring protection（Lower end in figure）Provided with top cover 15, on the top cover 15 be provided with it is described
The corresponding through hole 16 of contact pin 6.Top cover 15 can not also be set.
When not in use, ring protection covers 14 tops to the present invention（Lower end in Fig. 3）Higher than the top of contact pin 6（Under in Fig. 3
End）, due to the support of screw rod 11, ring protection set 14 will not be moved by compression；When mounted, bolt 4 passes through gear drive band
Dynamic screw rod 11 is moved up, and the through hole 16 of protective case top cover 15 is stretched out in the lower end of contact pin 6.
