Background
The crown band jack contact element is widely applied to a new energy automobile connector, the crown band is used as a main component in the crown band jack contact element, and the fixing or limiting mode of the crown band jack contact element influences the overall function of the crown band jack contact element. The existing connection mode of the crown band and the jack rear sleeve mainly comprises two modes of fixing or limiting, wherein one mode is that a fixing element is additionally arranged at the head of the jack rear sleeve and is used for fixing the crown band, but the fixing mode has a complex structure and increases the product cost; the other is that the annular groove is processed in the rear sleeve of the jack and used for limiting the head end and the tail end of the crown band, although the structure of the limiting mode is simple, the crown band cannot be axially fixed, and the crown band moves back and forth when the contact pin is plugged, so that the floating is large and the stability is poor.
SUMMERY OF THE UTILITY MODEL
For solving the problem that the current crown band jack contact member crown band fixing mode structure is complicated and the limit structure poor stability, the utility model discloses crown band jack contact member adopts the protruding fixed and unsteady mode of afterbody of crown band head, connects crown band and jack back cover.
The purpose of the utility model and the technical problem thereof are realized by adopting the following technical scheme. The foundation the utility model provides a novel crown band jack contact, including jack back cover and the crown band of assembly in jack back cover front end mounting hole, the crown band front end sets up a plurality of archs along circumference, thereby the jack back cover is seted up and is restricted crown band axial displacement's ring channel with this protruding stop cooperation, has between the spacing step that crown band rear end and mounting hole rear end set up and provides the axial clearance in axial extension space for the crown band at adaptation contact pin and crown band grafting in-process.
The purpose of the utility model is further realized by adopting the following technical measures.
According to the crown band jack contact piece, the front end hole of the jack rear sleeve is provided with the chamfer, and the chamfer is matched with the flanging arranged at the front end of the crown band.
The aforementioned socket-in-cap contact, wherein the protrusion has a circular or annular or square shape.
By the technical scheme, the head of the crown band is provided with the convex structure which is matched with the annular groove on the rear sleeve of the jack, so that the crown band can be prevented from axially shaking during plugging; the tail of the crown band adopts a floating structure which is not fixed, and when the adaptive contact pin is inserted, the tail of the crown band can be expanded along the axial direction under the action of the inserting force, so that the friction between the tail of the crown band and the contact pin is reduced, and the contact pin can be conveniently inserted and pulled out.
The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are described in detail with reference to the accompanying drawings.

Detailed Description
The following detailed description of the present invention will be made with reference to the accompanying drawings.
Please refer to fig. 1 to 4, a novel crown band jack contact, including jack back cover 1 and crown band 2 of assembly in the mounting hole 11 of jack back cover front end, wherein crown band 2 is for having the tubular structure of axial opening 21, is equipped with the reed 22 that a plurality of intervals set up between the front and back end of crown band 2, the reed 22 middle part is received the waist so that with 3 elasticity butts of adaptation contact pin, foretell crown band jack contact structure and theory of operation are prior art, no longer give details, and the utility model discloses the improvement point for this current crown band jack contact lies in: the front end of the crown band 2 is circumferentially provided with a plurality of protrusions 23, the jack rear sleeve 1 is provided with an annular groove 12 which is matched with the protrusions 23 in a blocking mode so as to limit the axial movement of the crown band, an axial gap 4 is formed between the rear end of the crown band 2 and a limiting step 111 arranged at the rear end of the mounting hole, so that in the process of splicing and matching of the adaptive contact pin 3 and the crown band 2, an axially extending space is provided for the crown band 2, and the rear end of the crown band 2 and the inner wall of the mounting hole form a guiding sliding fit relation.
In this embodiment, the crown band 2 is formed by processing and curling a metal band or plate, and has good conductivity and elasticity. The jack rear sleeve 1 is made of a metal material and has good conductivity, the jack rear sleeve 1 serves as a conductive supporting element for accommodating the crown band 2, and the mounting hole 11 of the jack rear sleeve is in interference fit with the crown band and used for limiting radial expansion of the crown band, so that the crown band and the adaptive contact pin are guaranteed to have certain contact holding force. The protrusion is circular, annular, square or other shapes, which the present invention is not limited to.
Preferably, a chamfer 13 is processed at the front end orifice of the mounting hole of the jack rear sleeve 1 and matched with a flanging 24 at the front end of the crown band, so that the crown band is conveniently arranged in the mounting hole.
As shown in FIG. 4, conventional plastics are installed to the spigot of contact pin 3 and are prevented touching finger cap 5, contact pin 3 with the utility model discloses when beginning to join in marriage to insert, the arch of hat ribbon front end is fixed with the ring channel cooperation, can prevent that the hat ribbon from rocking along the axial in the mounting hole, especially in the operational environment that the vibration is many, is favorable to keeping the stability of elastic contact. The rear end of the crown band 2 has a certain axial clearance with the limiting step 111, so that the rear end of the crown band is floating and unfixed, when the contact pin 3 is inserted, the contact pin 3 is in elastic contact with the reeds 22, the circular socket surrounded by the reeds is expanded, the rear end of the crown band 2 extends towards the rear end along the axial direction under the action of the insertion force of the contact pin, the strain of the crown band is released, and therefore the friction force during insertion is reduced, and the contact pin can be conveniently inserted and pulled out.
The above description is only a preferred embodiment of the present invention, and any person skilled in the art can easily modify, change or modify the above embodiments according to the technical spirit of the present invention without departing from the scope of the present invention.
