Description

Socket connector

The present invention relates to a kind of socket connector, refer to especially a kind of can effectively improve terminal and peg graft the time mechanical property and increase terminal and plug between the socket connector of contact area.

In recent years, along with the high speed development of various miniature electronic utensils such as technology such as mobile phone, portable computer, the application of socket connector on the miniature electronic device day by day increases, and occurred variously being useful on the different electronic installations and socket connector with multiple grafting function, related art sees also United States Patent (USP) the 4th, 393, and 283,4,846,719,4,978,310 and 5, case such as 092, No. 795.See also Fig. 6, existing socket connector mainly includes insulation shell 100, it is provided with the spliced eye 102 of the cylindrical docking section 101 that can make the plug insertion, conducting terminal 200,300 are separately positioned on the both sides in the socket connector spliced eye, it is respectively equipped with along the spliced eye centerline direction and extends projection and the suitable flexible contact site 201 of tool, 301, contact site 201,301 stretch in this spliced eye 102 and can with plug 8 conducting that connects, and aforementioned each terminal 200,300 respectively are provided with pin 202,302 extend outside the insulation shell, and can adopt the solid welding of surface adhesion technology on the corresponding circuit connection pad of circuit board.But, the elastic contact part 201,301 of the conducting terminal 200,300 of aforementioned existing structure contacts with the contact site 81 of plug 8 individually in one-sided, and the strength that can't clamping plug 8 effectively is provided and be located, therefore this plug 8 location in spliced eye 102 does not have enough steadinesss, very easily obscission occurs because of vibration.Moreover because terminal 200 is one-sided the contact with plug 8, its contact area is less relatively, and is prone to the not good situation of contact performance.

The objective of the invention is to, provide a kind of can effectively improve plug and insert the time terminal mechanical property and increase terminal and plug between contact area, and terminal is this plug of clamping and suitable active force is provided effectively, make plug be inserted to the precalculated position automatically and constitute good contact, and then make the better socket connector of telecommunication laser propagation effect.

Technical program of the present invention lies in: socket connector includes insulating body and several conducting terminals etc., this conducting terminal comprises first, second terminal of being located at and arranged on left and right sides in the insulating body spliced eye and the 3rd terminal of being located at the spliced eye rear end side, wherein first and second terminal is equipped with along the spliced eye centerline direction and extends and the suitable elasticity of tool and can keep the contact arm of good butt with plug, and extend insulating body outer with the pin of circuit board welding.Take the shape of the letter U and the 3rd terminal is rough, it comprises that one extends to be provided with the base portion of pin and to be positioned at the base portion both sides and is two elastic contact arms that are oppositely arranged, and the extending end of this two contact arm is slightly towards close mutually direction bending and form the larger area contact site and connect face.When banjo when this face that connects inserts, elastic contact arm can clamp plug, and borrow its elastic-restoring force to act on the plug, and and can produce a pulling force towards terminal inside, make plug to be inserted to the precalculated position of terminal automatically and well contact with its formation.

The invention has the advantages that: the plug of butt joint can be inserted to the precalculated position of socket connector automatically and constitute good contact, and the telecommunication laser propagation effect is better.

Below in conjunction with accompanying drawing and preferred embodiment the present invention is further described.

See also Figure 1 and Figure 2, socket connector of the present invention comprises members such as insulating body 1, the first terminal 2, second terminal 3 and the 3rd terminal 4.Wherein, insulating body 1 is the lengthwise body, the one side is made as front surface 11, relative opposite side then is made as rear surface 12, front surface 11 both sides respectively are provided with spliced eye 13, spliced eye 13 is towards insulating body 1 inner extension and be through to 12 places, rear surface, and can be inserted wherein by front surface 11 spliced eyes 13 places for plug 6.In addition, at the front surface 11 of insulating body 1 part of 13 of two spliced eyes and the signal terminal conduit 16 that upper surface 14 is provided with some channel form, the corresponding signal terminal 17 that accommodates transmission telecommunication or electric power in each conduit 16 then respectively is provided with for reference column (not shown) insertion of plug 6 between 16 liang of sides of conduit and spliced eye 13 and wherein and firmly docks location hole 15.In addition, side surface 18 middle parts at insulating body 1 two ends are assembled with the bonding pad 19 parallel with upper surface 14 respectively, socket connector can be welded and fixed on the circuit board.

First and second and three terminals 2,3 and 4 are mounted on and arranged on left and right sides and the rear end side in insulating body 1 spliced eye 13 respectively, this first and second terminal 2,3 has rectangle base portion 21,31 respectively, wherein base portion 21 is extended with elastic contact arm 23 and pin 25 towards the direction away from base portion 21 respectively along the both end sides of longitudinally, and the terminal suitably bending of this elastic contact arm 23 and convex to form a contact site 24 towards spliced eye 13 center lines; Base portion 31 then in the both end sides of longitudinally respectively towards extending Extendible flake 36 and pin 35 away from direction, and make elastic contact arm 33 in these Extendible flake 36 upper punches, it forms contact site 34 towards the extension of base portion 31 directions and its end towards spliced eye 13 center lines projection.The in addition both sides of this first and second terminal 2,3 all bend be provided with interference piece 22,32 with strong fix in spliced eye 13.

The 3rd terminal 4 slightly takes the shape of the letter U, it is provided with base portion 41, be extended with two elastic contact arms 43 that omit perpendicular to base portion 41 in each bending of these base portion 41 and arranged on left and right sides, and the extending end of this two elastic contact arm 43 slightly is bent to form a contact site 44 and connects face 46 towards mutual close direction.Moreover the bending of the bottom side of this base portion 41 is extended with the interference piece 42 of vertical configuration, with the 4 firm windings of the 3rd terminal to insulating body 1, relative opposite side then continuously bending also extend to form a pin 45 in the opposite direction.See also Fig. 3, Fig. 4 and Fig. 5, when plug 6 inserts in the spliced eyes 13 appropriate depth and makes its contact site that slightly is reverse taper 61 terminal set contra bevels 612 touch the face that connects 46 (the 3rd diagram) of the 3rd terminal 4, at this moment, further the application of force promotes plug 6, because the interaction between the inclined-plane, its contra bevel 612 will and strut two elastic contact arms 43 along the face of connecting 46 slips, make plug 6 successfully insert 43 of two elastic contact arms.When the contra bevel 612 of this plug 6 is in contact with it 611 junctions, inclined-plane and contacts with the contact site 44 of this two elastic contact arm 43, elastic deformation amount's maximum (as shown in Figure 4) of elastic contact arm 43.When plug 6 continues to insert, under the elastic-restoring force effect, elastic contact arm 43 is tendencies toward shrinkage, this moment is because elastic-restoring force directly acts on the contact inclined-plane 611 of plug 6, by mechanics principle as can be known, the restoring force that vertically acts on the contact inclined-plane 611 will produce a component (axial tension) along plug 6 axial normals, locate (as shown in Figure 5) and plug 6 is pulled to the 3rd terminal 4 default contact location.In addition, because elastic contact arm 43 contact sites 44 have suitable width and area, can guarantee that 6 of itself and plugs have enough contacts area and keep excellent electrical property to contact.
