Technical field
The present invention relates to a kind of connector for electric current or signal converting, particularly relate to a kind of contact and strengthen connector reliably with coordinating between insulator.
Background technology
Existing a kind of connector as shown in Figure 1, 2, comprise housing 1, the through hole before and after running through is provided with in housing 1, be fixedly installed by insulating element in the through hole of housing and have contact 2, insulating element comprises and is fixedly installed on front insulator in housing 14 and rear insulator, and the rear of rear insulator is also provided with afterbody insulator.Contact 2 is located in the endoporus of front insulator, rear insulator and afterbody insulator.What the leading section of front insulator 4 was arranged on varus fixedly turns edge 5.The location that contact 2 is realized in insulating element by locating detent 3, locating detent 3 comprises a cylindrical body, the inwall of cylindrical body being provided with one end is fixed on the inwall of cylindrical body, other end free inclination stretches to the Location resilient piece of the axis of cylindrical body, locating detent 3 is set on contact 2 by its cylindrical body, and locating detent is in the endoporus of front insulator.The front end face top of locating detent be pressed in front insulator 4 fixedly turn edge 5 outer rim position, the rear end face top of locating detent is pressed on the front end face of rear insulator.Contact 2 is provided with set collar 6, the front end face top of set collar 6 be pressed in front insulator 4 fixedly turn edge 5 position, inner edge, the rear end face of set collar 6 and the Location resilient piece top press-fit of locating detent, thus realize fixing in housing 1 of contact.When assembling, first front insulator is assemblied in the endoporus of housing 1, then locating detent is plugged in the endoporus of front insulator 4, load onto rear insulator and afterbody insulator more successively, finally from rear end, contact 2 is penetrated the endoporus of each insulator, when set collar touches the Location resilient piece of locating detent, Location resilient piece can be extruded, make Location resilient piece strain, after set collar crosses Location resilient piece, Location resilient piece restores to the original state and presses with the rear end face top of set collar.Because contact needs the elastic force overcoming Location resilient piece, therefore need when assembling on contact, apply certain pushing force, when operating, if the size of pushing force controls bad, the set collar of contact will bump against fixedly turning edge of front insulator, due to structural limitations, the axial dimension fixedly turned edge is less, generally only have 0.76-1.1mm, this just makes fixedly to turn edge and is easy to be touched part and crashes through, and causes front insulator damage.
Summary of the invention
The object of the present invention is to provide and a kind of strengthen connector, with solve the contact that occurs in connector device timing in prior art by front insulator fixedly turn edge crash through cause before the problem of insulator damage.
For achieving the above object, the present invention adopts following technical scheme: a kind of reinforcement connector, comprise housing, running through in the endoporus of front and back of housing is fixedly installed contact by insulating element, contact has set collar, insulating element is fixedly installed in housing, insulating element comprises front insulator and rear insulator, contact is fixed in the endoporus of front insulator and rear insulator by locating detent, contact is fixed in the endoporus of front insulator and rear insulator by the metal sleeve be plugged in the endoporus of front insulator by described locating detent, the outer peripheral face of metal sleeve have towards the positioning table terrace of front end, positioning table terrace and front insulator top press-fit, the rear end face of metal sleeve and the leading section top press-fit of rear insulator, the location that the leading section of metal sleeve is provided with varus turns edge, the inner margin portion top press-fit that the front end face of locating detent and location turn edge, the rear end face of locating detent and the leading section top press-fit of rear insulator, the inner margin portion top press-fit that the front end face of described set collar and location turn edge, the rear end face of set collar and the Location resilient piece top press-fit of locating detent.
Described positioning table terrace is the front end face of the locating flange of the evagination of the rearward end being arranged on metal sleeve.
The rear end face of described front insulator is provided with in locating flange place counterbore is set, the dead in line of the axis of counterbore and the endoporus of front insulator is set, described positioning table terrace by with the top press-fit of end face of counterbore and front insulator top press-fit are set.
The rear end face of described locating flange is concordant with the rear end face of metal sleeve, and the rear end face of metal sleeve is concordant with the rear end face of front insulator.
The rear of described rear insulator is provided with afterbody insulator, and afterbody insulator is in the endoporus afterbody of housing, and afterbody insulator is located on contact by its inner hole sleeve.
Metal sleeve is inserted with in the endoporus of front insulator of the present invention, metal sleeve and front, rear insulator top press-fit, the inner margin portion that the location that is pressed in metal sleeve turns edge is pushed up in the front end of locating detent, the top, rear end of locating detent is pressed on rear insulator, the front end face top of the set collar of contact is pressed in the position, inner edge of locating and turning edge, the rear end face of set collar and the Location resilient piece top press-fit of locating detent, when assembling, pushing force is applied on contact, contact extruding Location resilient piece crosses Location resilient piece to make the set collar of contact, material due to metal sleeve is metal, intensity is larger, even if the pushing force be applied on contact is larger, location also can not turn edge and crash through by contact, the setting of metal sleeve enhances the intensity of whole connector.
