Description
Technical field
The present invention relates to a kind of D-SUB connector, specifically a kind of D-SUB connector with protective case.
Background technique
D-SUB socket and plug are the high performance-price ratio general connector widely applied in industrial equipment, D-SUB connector master
It to include glue core, the terminal loaded on glue core, the metal shell being wrapped in outside glue core, the plastic casing that is placed on outside metal shell
And it is arranged in the fastening screw on plastic casing.
Although being protected currently, contact pin entirety outermost of the D-SUB connector in the market on D-SUB connector is arranged
Protection structure, but in daily placement and in use, middle section contact pin is easy to touch staff, since pin head is sharp,
It can cause unnecessary injury.With the use of etc. due to, can will there are the material of a part of contact pin is softer, when improper use
Contact pin bending, can not normal use so as to cause entire D-SUB connector.
To solve the above-mentioned problems, the prior art proposes a kind of D-SUB connector of slotting needle protection structure of band, master
Wanting structure includes 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 is equipped with several contact pins in the plug casing, be arranged on the every contact pin for avoid contact pin bending by
The protection structure of damage.The protection structure includes telescopic rod, and the contact pin is located on the inside of telescopic rod, described telescopic rod one end and is inserted
The connection of casing bottom, telescopic rod is interior to be equipped with spring, and the spring is fixed on telescopic rod inner wall.
It is above-mentioned of the existing technology the disadvantage is that: structure is complicated, it is difficult to implement；After accidentally having compressed telescopic rod, still
So there are security risks.
Summary of the invention
The purpose of the present invention is to provide a kind of D-SUB connector with protective case, it is of the existing technology to solve
Structure is complicated, it is difficult to implement, there are problems that security risk.
To achieve the above object, the present invention provides the following technical scheme that a kind of D-SUB connector with protective case,
Including glue core and the shell that is wrapped in outside glue core, the shell includes plug casing and Socket casing, plug casing and socket
Shell is connected with each other by screw bolt and nut；In the plug casing be equipped with several contact pins, on the Socket casing be equipped with
The corresponding jack of the contact pin, which is characterized in that be equipped in one end periphery that the plug casing is equipped with contact pin by whole contact pins
It covers in internal ring protection set, the both ends of ring protection set are fixedly connected with one end of a screw rod respectively；Described
The both ends of plug casing are rotatablely connected a driven gear respectively, the axle center of the driven gear be equipped with screw hole, each screw rod it is another
One end is threaded through the screw hole in the driven gear axle center；It is arranged below integrated driving gear in the nut of the bolt, and with
The corresponding driven gear intermeshing.
It is equipped with top cover on the top of ring protection set, through-hole corresponding with the contact pin is equipped on the top cover.
Whole contact pins are covered in internal protective case the invention has the advantages that being provided in plug end, and with bolt tooth
Wheel transmission connection, in use, protective case top is higher than the top of contact pin, and protective case will not be disappeared by compression movement
In addition to security risk；During installation, bolt drives screw rod to move up by gear drive, and contact pin extends downwardly protective case, no
Influence normal use.

Specific embodiment
As shown in figure 3, a kind of D-SUB connector with protective case of the present invention, including glue core and it is wrapped in outside glue core
Shell, the shell includes plug casing 1 and Socket casing 2, and plug casing 1 and Socket casing 2 pass through bolt 4 and nut
(cylinder that top is equipped with screw hole) 8 is connected with each other；(lower end) is equipped with several contact pins 6 in the plug casing 1, in the socket shell
Body 2 is equipped with jack 5 corresponding with the contact pin, which is characterized in that is equipped with one end periphery of contact pin 6 in the plug casing 1
Equipped with by 6 sets of whole contact pins, in internal ring protection set 14, which covers (left and right) both ends of 14 upper ends respectively with one
The lower end of root screw rod 11 is fixedly connected；Be rotatablely connected a driven gear 12 respectively at the both ends of the plug casing 1, this from
The axle center of moving gear 12 is equipped with screw hole, and the upper end of each screw rod 11 is threaded through the screw hole in 12 axle center of driven gear；Described
The nut of bolt 4 be arranged below integrated driving gear 13, and be intermeshed with the corresponding driven gear 12.
The ring protection set 14 top (lower end in figure) be equipped with top cover 15, on the top cover 15 be equipped 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 (lower end in Fig. 3) and is higher than the top of contact pin 6 (under in Fig. 3 the present invention
End), due to the support of screw rod 11, ring protection set 14 will not be moved by compression；During installation, bolt 4 passes through gear drive band
Dynamic screw rod 11 moves up, and the through-hole 16 of protective case top cover 15 is stretched out in the lower end of contact pin 6.
