Description
Technical field
The utility model relates to a kind of D-SUB connector, and more particularly, it relates to a kind of D-SUB connector with operator guards.
Background technology
D-SUB socket and plug are the high performance-price ratio general connectors widely applied in industrial equipment, and D-SUB connector mainly comprises glue core, the terminal be loaded on glue core, the metal shell being wrapped in glue core outside, the plastic casing being placed on metal shell outside and the holding screw be arranged on plastic casing.
At present; although the overall outermost of the contact pin of the D-SUB connector on market on D-SUB connector arranges operator guards, lay daily and use, mid portion contact pin easily touches staff; because pin head is sharp-pointed, 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 by contact pin bending, thus cause whole D-SUB connector normally to use during improper use.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of D-SUB connector with contact pin operator guards.
For achieving the above object; the utility model provides following technical scheme: a kind of D-SUB connector; comprise glue core, be loaded on the terminal on glue core and be wrapped in the shell of glue core outside; described shell comprises the first housing and the second housing; being provided with some contact pins in described first housing, described every root contact pin being all arranged with the operator guards for avoiding contact pin bending impaired.
By adopting technique scheme, contact pin outer setting operator guards, both can protect staff to be accidentally injured by contact pin, and contact pin also can be protected accordingly not by bending, damage, fail safe when effectively improve use and ensure that the integrality of D-SUB connector.
The utility model is set to further: described operator guards comprises expansion link, and described contact pin is positioned at inside expansion link, and described expansion link one end is connected with the first housing bottom, is provided with spring in expansion link, and described spring is fixed on expansion link inwall.
By adopting technique scheme, Telescopic rod structure is simple, technology maturation, and expansion link is enclosed within outside contact pin, with reach improve use time fail safe and ensure the object of integrality of D-SUB connector.
The utility model is set to further: described second housing is provided with jack, described expansion link diameter is greater than jack diameter, some grooves are provided with in described first housing, expansion link one end is connected to inside grooves, some reference columns for preventing expansion link from offseting are provided with in described groove, inside grooves is fixed in reference column one end, and described reference column is positioned at expansion link bar wall.
By adopting technique scheme, expansion link diameter is greater than jack diameter, can expansion link be effectively avoided to be strayed into jack, expansion link is fixed on inside grooves, contact pin coordinates with jack in use, and the expansion link outside contact pin can embed in groove, can not affect coordinating between contact pin with jack, reference column can have fixing expansion link position, prevents it from offseting.
The utility model is set to further: the hollow cylinder that described expansion link comprises some coaxial settings is also sheathed successively in the axial direction, and be slidably connected between described each hollow cylinder, hollow cylinder diameter reduces successively along telescopic direction.
By adopting technique scheme, Telescopic rod structure is simple, can effectively protect contact pin and not affect use.

Embodiment
Referring to figs. 1 through Fig. 3, the utility model D-SUB connector embodiment is described further.
As shown in Figure 1 to Figure 3; a kind of D-SUB connector; comprise glue core 3, be loaded on the terminal on glue core 3 and be wrapped in the shell of glue core 3 outside; described shell comprises the first housing 1 and the second housing 2; be provided with some contact pins 6 in described first housing 1, be provided with outside described contact pin 6 for the protection of the impaired operator guards of contact pin 6 bending.Described operator guards comprises expansion link 7, and expansion link 7 is placed on outside contact pin 6, fixes bottom described expansion link 7 one end and the first housing 1.Described second housing 2 is provided with jack 5, and described expansion link 7 diameter is greater than jack 5 diameter, is provided with some grooves 9 in described first housing 1, and it is inner that expansion link 7 is fixed on groove 9.Be provided with some reference columns 10 for preventing expansion link from offseting in described groove 9, it is inner that groove 9 is fixed in reference column 10 one end, and described reference column position 10 is in expansion link 7 bar wall.Described expansion link 7 is made up of some hollow cylinders, and hollow cylinder diameter increases from top to down successively, clamping between described hollow cylinder.
In order to better fixed housing, first housing 1 is provided with bolt 4, the second housing 2 corresponded is provided with nut 8, bolt 4 and nut 8 with the use of, abundant fixed housing body, above-mentioned expansion link 7 length is slightly longer than contact pin 6, when not using D-SUB connector, staff can be protected can not to be accidentally injured by contact pin 6, also the damaged or bending of contact pin 6 can effectively be avoided, when using D-SUB connector, by contact pin 6 tip alignment jack 5, contact pin 6 and jack 5 one_to_one corresponding, after aligning, contact pin 6 is inserted, because expansion link 7 diameter is slightly larger than the diameter of jack 5, along with contact pin 6 enters jack 5, expansion link 7 can be propped up by the glue core 3 in the second housing 2, expansion link 7 is retracted, until contact pin 6 coordinates completely with jack 5, it is inner that expansion link 7 will embed groove 9, described expansion link 7 material therefor is soft plastic, first housing 1 and the second housing 2 all can be divided into fore shell and back cover, being provided with contact pin 6 with jack 5 place is fore shell, the fore shell material therefor of described first housing 1 and the second housing 2 is tinplate, the back cover material therefor of the first housing 1 and the second housing 2 is plastics, insulating effect can be played, improve safety in utilization.
The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection range of the present utility model.
