Description

Movable electrical connector

The present invention relates to electric connector; Particularly relevant being installed on the every wiring board is by the movable electrical connector that the interconnective pair of connectors of the circuit that constitutes is in the circuit board constituted.

When the circuit that is formed on 2 wiring boards such as vehicle audio mechanism movement (カオディオメカデッキ) and main printed circuit board (PCB) is interconnected, often there is the situation that 2 wiring boards each other can not fine aligning.Although on certain program, be difficult to aim at,, need connector itself to be in the movable electrical connector of movable state within the specific limits in order to realize interconnecting simply securely.And when between 2 wiring boards, being offset because of the vibratory impulse occurrence positions, essential too movable electrical connector.

So movable electrical connector also can be considered to interconnect with flexible cables such as flat cables between wiring board.Yet, in scope of activities under mm level situation, it is disclosed for example to open No. 70677 communiques of flat 4-3 as the spy, use the case (fixedly case part and movable case part) of 2 isolating constructions, flexible terminal by Z-shaped structure makes between 2 cases and is connected, and She Ji movable electrical connector has reached the practical stage like this.

But, in above-mentioned existing movable electrical connector, because pair of connectors produces too big stress on terminal when plug, so terminal or case are impaired, for prevent between terminal or terminal and external conductor between short circuit, the limiter of specified campaign scope then must be set between 2 cases.Fixing and movable case is partly being adorned many terminals in another group, so be difficult to reliablely and stablely assemble mutually 2 cases.

Therefore, the object of the invention is a kind of movable electrical connector of providing such can be easy to the specified campaign scope, and terminal or case are not impaired during plug; And the manufacturing assembling is simple, cheap, unfailing performance is high.

In order to realize the foregoing invention purpose, movable electrical connector of the present invention will fix by the terminal that the header portion that tilts is inwards arranged and movable case partly is connected to each other.Thereby, utilize this oblique cross beam part, it is flexible fully to invest terminal, and simultaneously, even because movable case part moves in the plane, terminal can not stretch out beyond the case yet, so can remove the sorrow that contacts with external conductor.And the formation earlier when terminal is assembled of fixed and movable case part is whole, treats to cut off after terminal installs again and separates, and above-mentioned formation makes the assembly production of movable electrical connector simple, and cheap.

With reference to the accompanying drawings, describe the most preferred embodiment of movable electrical connector of the present invention in detail.

Fig. 1 is to use the cutaway view of jockey between the printed circuit board (PCB) of active type connector of the present invention.This jockey has movable electrical connector of the present invention (or bullet connector) 10 and butt connector (or block joint) 100.

Movable electrical connector 10 is by being fixed on elongated fixedly case part 30 on the 1st wiring board 20 and movable case part 40 and 2 row's terminals 50 are formed, and 2 arrange terminals 50 connects 2

case parts

30,40 each other movably from two sides.As described below, it is desirable to, 2

case part

30,40 usefulness insulating plastics material are molded into integral body, are housed to terminal 50 and cut off afterwards separately, and are removable each other.

Wiring board 20 has best with a determining deviation, and 2 rows that form as 2mm plate good through hole 22,24.Insert the soldering pin 51 of the terminal 50 that stretches out from the fixedly case part 30 of movable electrical connector 10 in this through hole 22,24 downwards.This soldering pin is done soldering by known method, is connected with the conductive path (operation) that forms on wiring board 20 surfaces.

Fixedly case part 30 is roughly rectangular, the accepting groove 32 that the terminal that is made of separates walls 31 in both sides formation is pressed into.In each terminal containing slot 32, form the traverse furrow 33 and the recess 34 parallel and bigger of fixed terminal 50 with above-mentioned traverse furrow 33.Movable case part 40 is a kind of slightly rectangular members, is provided with the gap with fixing case part 30 tops, and configured in parallel.Be to have and fixedly the terminal containing slot 32 corresponding grooves 42 of case part 30 and the groove 44 that is used for fixing on this activity case part 40.

Terminal 50 has soldering pin 51, barbed standing part 53, the header portion that slightly is the ear shape 54 that tilts inwards, limiter part 55, neck 56, the corbel back slab shape contact part 57 of stretching out and the standing part 58 that is pressed into traverse furrow 44 internal fixation of movable case part 40 in the recess 34 of fixing case part 30.As shown in the figure, terminal 50 slightly is tabular,

By conductive metal plate stamping and forming (stamping-out processing).At soldering pin 51 and neck 56, process strip bulge along the Center Length direction, can play the reinforcement effect.And though form narrow space between soldering pin 51 and the neck 56, the header portion 54 that the connection between them is extended by inwardly being inclined upwardly after stretching out is downwards again realized.The below of adding neck 56 from the upper end of this header portion 54 constitutes approximate shape of ears, so the effective length between soldering pin 51 and the corbel back slab shape contact 57 has increased, consequently invests terminal 50 sufficient elasticity and even flexible.Also have, be formed slopely the technique effect that header portion 54 produced and treat the back narration.

The limiter part 55 of terminal 50 is by neck 56 lower end horizontal expansions.This limiter part 55 is contained in the lateral recess 34 of fixing case part 30.The width dimensions of the width of this limiter part 55 and recess 34 gives selected earlier respectively.Not to applying under the common state of external force on terminal 50 or the electric connector 10, limiter part 55 is positioned at the center of recess 34, and being noted that at lower wall surface on the recess 34 and limiter part should have certain interval between the ora terminalis about in the of 55.Recess 34 lateral depth selected should be that the front end apart from limiter part 55 has a fixed gap.Therefore, as if left and right directions pushing activity case part 40 in figure, then limiter part 55 any front ends contact recess 34 inwall of left and right sides terminal 50 determine maximum addendum modification with this.

Also have when movable case part 40 when direction is squeezed or stretches up and down, by contact the excessive displacement or the deflection of the limiter part 55 prevention terminals 50 of terminal 50 with lower wall on the recess 34.Such displacement is for movable electrical connector 10, when resulting from butt connector 100 by plug, utilize this fixedly recess 34 of case part 30 and limiter part 55 of terminal 50, on terminal 50, produce excessive stress in the time of can avoiding making flexible lamp connector 10 and butt connector 100 to insert or extract.And in the traverse furrow 44 of movable case part 40, be pressed into the standing part 58 of terminal 50.A standing part 53 is pressed into the fixedly traverse furrow 33 of case part 30; Another standing part 58 is pressed into the traverse furrow 44 of movable case part 40, so terminal 50 has interconnective function.On 2 standing

parts

53,58, form thorn (hangnail), flexibly connect mutually between 2 case parts 30,40.As hereinafter described, terminal 50 is pressed into fixedly case part 30 and movable guard part shell 40 from side direction respectively, and is held.

Then, with reference to Fig. 1 butt joint (block) connector 100 with movable electrical connector 10 cooperations of the present invention is carried out simple declaration.This butt connector 100 for example is the connector of mounted on surface SMT on other wiring board 120.The movable case part 40 of these butt connector 100 accepting activity type electric connectors 10.Case 130 with band recess 131 also bigger than this activity case part 40.The recess 131 of this case 130 is made of bottom surface 132 and 2 sidewalls 133,134.As shown in the figure, between 2 sides of 2 sidewalls 133,134 and movable case 40, wish and set the space as far as possible, alleviate to 2 connectors 10 and 100 to alignment request.

At the case 130 of butt connector 100, its bottom surface 132 is provided with 2 row's terminals 150.Above-mentioned each terminal 150 has the forked contact part 151 of adjustment, cooperates with the corbel back slab shape contact 57 of movable electrical connector 10 broads to contact.And the connection that is connected with the bottom surface 132 of case 130 is arranged or be pressed into standing part 152 at terminal 150 mid portions; Also have the soldering shank to divide 153 at the other end, its bottom surface 132 by case 130 is protruding, opposite each other towards transverse curvature into about right angle (parallel) with wiring board 120 surfaces.

As shown in the figure, on the 132 liang of lateral surfaces in the bottom surface of case 130, constitute taper 135.After terminal 150 being pressed in the opening of bottom surface 132 of case 130, divide 153 to make it crooked along these taper 135 extruding soldering shanks.Remove this extruding force then because the elasticity of the metal material of terminal 150 produces bounce, so the surperficial almost parallel of final and wiring board 120 when one.On the surface (not shown) of dividing 153 wiring board 120 corresponding to this soldering shank, for example form the circuit pad that has applied paste soldering material.Divide heat emission line such as irradiation infrared ray or laser on 153 at this soldering shank, make solder fusing, be soldered on the wiring board 120.In addition as shown in phantom in FIG., on the optional position, 132 outside, bottom surface of connector 100 cases 130, form locator protrusions 136, do friction and be connected with being formed on the quite locational conjugate foramen (not shown) of wiring board 120, can strengthen the adhesion of wiring board 120 and connector 100.

If use above-mentioned movable electrical connector 10 and butt connector 100, for the situation of wiring board about 20,120 (laterally) direction misalignment, can cooperate with the diverse location of wide cut corbel back slab shape contact 57 by the forked contact part 151 of the adjustment of terminal 150 to be adapted to.And the misalignment or the interval error of (vertically) direction about two wiring boards 20,120 are alleviated by the length of fit of adjusting terminal 50,150.Have, the movable case part 40 of movable electrical connector 10 is because of the flexibility of the header portion 54 that contains terminal 50, because up and down and be movably in the certain limit of the left and right sides, so offset the mobile of two wiring boards 20,120 effectively again.And the header portion 54 of terminal 50 is direction inclination inwardly from bigger fixedly case part 30 towards less movable case part 40.Therefore, can understand, even movable case part 40 relative fixed case parts 30 move to left and right direction, terminal 50 does not stretch out
