Abstract
The utility model discloses an elastic pin for an electric connector. An electric contact member is formed from the utility model and a rigid tubular jack which are arranging in a matching mode. The elastic pin comprises a pin main body, the pin main body is an integral structure of which the middle is big, both ends of the integral structure are small, and the middle section of the pin main body is provided with an elastic body which is in shape of a waist drum and is formed from a plurality of convex elastic sheets; the tail of the elastic pin is pressed with a pressing piece, and the pin main body is formed by one-step punching in a mould. Processing and manufacture are simple. The elastic pin has the advantages of simple and stable structure, and strong practicability; the small volume of the utility model can be designed; the utility model is especially suitable for various miniature electric connectors of which the volume is in a high requirement.
Description
Technical field
The utility model relates to a kind of contact component of electric connector, is meant a kind of elastic contact pin of electric connector specifically, belongs to the electronic devices and components field.
Background technology
The contact of traditional electric connector generally all adopts rigidity contact pin, flexible jack, and adopts flexible contact pin, rigidity jack can make the volume-diminished of contact pin and jack under the prerequisite that does not reduce contact performance, thereby has correspondingly improved the density of contact.
Present existing elastic contact pin is generally stranded structure, the a branch of elastic metallic yarn that is intertwined is processed into small in the end and big in the middle dolioform, utilize the elasticity tension of elastic metallic yarn itself realize with the rigidity jack between reliable the contact and electrical connection, but the rigidity of this stranded elastic contact pin is poor, occuring bending and deformation easily even fractureing when inserting with the rigidity jack, thereby useful life is short, this in addition structure precision requires than higher, the processing technology complexity, make product percent of pass low, the corresponding raising of cost.
Utility model patent ZL94211070.6 discloses a kind of elasticity Linear spring pin that is used for electric connector, form conduction with the tubular receptacle of rigidity and contact idol, its elastic contact part by spring wire in the shape of a spiral shape around the nook closing member surface, the spring wire of front guide end and nook closing member are welded together and are hemisphere, it is one with it with the backshank pressing that afterbody has pressure ring, be that outwardly-bent the arching upward of spring wire is cydariform at last, the enveloping surface two ends are thin, middle thick.This structure is that spring wire is welding on the nook closing member as the elastic contacting part of contact pin, and because of must all carrying out melting welding to every spring wire, processing and fabricating is more time-consuming, and the elastic contact pin complex structure that makes like this, and fastness is not high yet.
Summary of the invention
The utility model provides a kind of elastic contact pin of electric connector of integral structure, this contact pin simple in structure, and processing and fabricating is simple and easy, and is practical.
A kind of elastic contact pin of electric connector, form the conductive contact piece of electric connector with the rigid tubular jack of supporting setting, described elastic contact pin comprises the contact pin body, the contact pin body is an integral structure small in the end and big in the middle, and its interlude is formed the elastomer of swelling-waist shape by the flexure strip of some protrusions.
Described flexure strip is the 2-4 sheet.
The outer ring pressing of described contact pin body afterbody has the pressing part.
Described contact pin body adopts mould one time punching molded.
The utility model protrudes into dolioform integral structure in the middle of contact pin is designed to, adopt the die stamping moulding, technology is simple and easy, this contact pin simple and stable structure, the wire that its resilient contact has replaced the twisted wire elastic contact pin to adopt by sheet metal, elasticity still is that rigidity all is greatly improved.And the volume of the contact pin of this structure and supporting jack can be provided with smallerly, has improved the density of electric connector conductive contact piece, and practicality is fine, is particularly useful for all kinds of miniature electric connectors high to volume requirement.
Description of drawings
Fig. 1 is a user mode reference view of the present utility model;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is that Fig. 2 C-C is to generalized section.
Embodiment
As shown in Figure 1, a kind of elastic contact pin A of electric connector forms the conductive contact piece of electric connector with the rigid tubular jack B of supporting setting.
As shown in Figure 2, elastic contact pin A comprises contact pin body 1, contact pin body 1 is an integral structure small in the end and big in the middle, surround the elastomer of swelling-waist shape from the plurality of elastic sheet metal 3 of the head of contact pin body 1 and rear portion projection, resilient contact as contact pins A, the outer ring pressing of contact pin body 1 afterbody has pressing part 2, can be used for connecting drawing lead all afterbody pressing parts that this pressing part can be traditional contact pin any.Contact pin body 1 adopts mould one time punching molded according to said structure.
Fig. 3 is the generalized section of resilient contact in the middle of the elastic contact pin A, and for the resilient contact that makes contact pin body 1 has better elastic and rigidity, sheet metal 3 generally is designed to the 2-4 sheet.
During assembling, with the elastic contact pin A that has made the position of design in advance of packing on the electrical connector plug, be the radius of the maximum protruding radius that encloses of dolioform resilient contact in the middle of the elastic contact pin A greater than jack B, when elastic contact pin A is inserted jack B, the volume that this resilient contact is subjected to dwindling from the active force of jack B hole wall himself enters jack B, support the inwall that invests jack B again owing to the elasticity tension of itself tightly, thereby realize the reliable electrical contact effect.Adopt the contact pin of this structure and the volume of jack can be provided with smallerly, thereby the density of electric connector conductive contact piece improves relatively, be particularly useful for all kinds of miniature electric connectors high volume requirement.
