Description

Divided connector

Technical field

The present invention relates to the connector technique field of transmission cable.

Background technology

The existing connector that is used for optical cable or cable, it is that afterbody feeds for cable ends that one class is arranged, the connector of the oral area inserting of head and other connectors, for the ease of being connected of cable and contact pin parts, can be with before the connector shell, back split setting, and it is preceding, the back casing parts generally are to join by the card of lead key and opening to be connected, before after being connected, can not axially relatively move between the back casing, because connector has the designing requirement of elastic floating in the axial direction of contact pin parts, the contact pin parts of this class split structure housing generally are to be inserted in the housing by activity elasticity inserting mode, and when the contact pin part dimension was not suitable for plug-in mounting in housing and need directly is connected on the connector shell, the connector shell of the branch body structure that is connected obviously can not satisfy the needs of design.

Summary of the invention

The object of the present invention is to provide a kind of housing parts along the line the cable channel axis to the divided connector of elastic floating.

Technical scheme of the present invention is: a kind of divided connector, establish the connector shell of cable passage in comprising, described housing is by first, the housing parts of establishing the cable passage in the second two is pegged graft and is constituted, contact pin installation end and cable that a end away from inserted terminal of two housings parts is respectively connector feed end, it is characterized in that: the inserted terminal of first housing parts is provided with the connection tongue, the inserted terminal of second housing parts is provided with for the slot that connects tongue activity inserting, the cell wall of slot is provided with the drop-proof structure that retaining cooperates, first with tongue, be respectively equipped with corresponding cable passage first on axially on second housing parts, the second axial limiting structure; First, second housing parts is by connecting tongue and slot activity inserting, and realizes that with the drop-proof structure on the slot axial anti-avulsion elasticity is connected by the spring and the tongue of top dress between first, second axial limiting structure.

Described connection tongue is two tongues that are relatively arranged on the inserted terminal of first housing parts, and described spring is held between two tongues, and spring has the inner ring that wears for cable; Described two slots corresponding with tongue are relatively arranged on the inwall of cable passage of second housing parts, and the notch of slot is logical is located at the reach the standard grade edge of cable access portal of the second housing parts grafting end face.

Described drop-proof structure is the stopping-receding bench terrace in the anti-avulsion opening and the barb on the tongue on the cell wall of slot.

Described tongue is the arc corresponding with the spring profile with the surface of spring contact.

Described first, second housing parts is the being used to flat shell that with fine intert of depth of section size greater than width dimensions, described spring is the spring of cross section approximate ellipsoidal, and the major and minor axis of the oval cross section of spring is the height and the Width in corresponding flat shell cross section respectively; The inwall of first, second housing parts is provided with the spring guide groove, the logical edge of being located at the cable access portal of the notch of spring guide groove, the bottom land of spring guide groove forms the axial limiting structure of joining with the end top of spring, and the side channel wall shape of spring guide groove is corresponding with the spring profile.

Tongue, slot on described first and second housing parts is on the sidewall on the Width, and the spring guide groove is on the sidewall on the short transverse of first and second housing.

Described spring guide groove is for connecting the groove of sidewall.

One of them of described first, second housing parts is the contact pin positioning seat, and another is to have the lock sleeve that cable feeds end, is fixed on before the contact pin parts on the contact pin positioning seat front end face.

Described contact pin parts are connected by safetied pin and contact pin positioning seat end, and the afterbody of safetied pin cooperates with the housing parts axial limiting, and the head of safetied pin plugs and is anchored in the pin hole set in the contact pin parts.

Has the locking key that is used for being fixed on housing outer surface on the described connector shell with the elasticity of socket cooperation, locking key comprises that elasticity is suspended in the hammerlock of connector shell surface and the elastic arm that elasticity is fixed on the connector case surface, be connected with the bulge-structure that the position is higher than hammerlock between elastic arm and the hammerlock, the link position of described elastic arm and connector shell feeds end near cable, the free end of hammerlock is near the contact pin installation end of connector shell, described bulge-structure forms the limiting section that cooperates along block with the mouth of socket with the coupling part of hammerlock, and the finger that the bulge-structure top has for finger presses touches portion.

Two housings parts of the present invention realize that by the cooperation of spring roof pressure and drop-proof structure the elasticity of anti-avulsion connects, and the guiding by tongue and slot realizes axial elastic floating, thus the contact pin installation end that the satisfies divided connector demand of other end elastic floating relatively.

In addition, connection tongue of the present invention and spring are the clamping setting, and the inner ring of spring can hold that cable is logical to be established, and makes spring easily assembling and guiding, also makes the overall structure of connector compact more simultaneously.

Further, connector of the present invention is flat connector, in order further to save the space, the spring guide groove is set in the cable passage simultaneously, spring is set to the sub-elliptical type accordingly, and form the axial limiting structure of spring at the bottom land of spring guide groove, and utilize the sidewall spaces of connector case body component to install and retainer spring, make the structure of connector compact more.

In addition, the locking key of connector of the present invention has the bulge-structure that is higher than hammerlock, the finger portion of touching at this bulge-structure top makes the feel of pushing better, the bulge-structure that is higher than hammerlock simultaneously can be on hammerlock form naturally with the socket mouth along the limiting section that block cooperates, make connector when pegging graft, can recognize the contact pin installation end and whether put in place and prevent that grafting is excessive from the outside; In addition, the cable of the close connector of the stiff end of locking key feeds end, makes connector when throwing off, and is not easy to cause clamping stagnation with the cable winding on the pulling traffic direction.

Further, described hammerlock and connector case surface be arranged in parallel, are beneficial to guiding when inserting, and difficult simultaneously and cable takes place to intersect and twines.

And the described finger portion of touching is that the finger of ledge structure and elastic arm joint touches the plane, and the feel of finger presses is better.
