Description

Socket connector

[technical field]

The utility model is relevant a kind of socket connector, refers in particular to a kind ofly to link to each other with cable and be immobilizated in module type socket connector on the printed circuit board (PCB) by set align member.

[background technology]

The module type socket connector is widely used in the Network Transmission of telephone or data communication, existing this module type socket connector generally is directly to be immobilizated on the printed circuit board (PCB) to plug for the banjo connector, correlation technique discloses in No. the 240879th, TaiWan, China and No. 322214 patent to some extent, described patent has disclosed a kind of conducting terminal and has been welded in module type socket connector on the printed circuit board (PCB), and this socket connector cooperates with this socket connector of assist location with the corresponding hole of printed circuit board (PCB) by set pair of columns in both sides in the middle of its bottom surface.But, when the conducting terminal of above-mentioned socket connector links to each other with cable, the set cylinder in both sides provides the fixing effect in the middle of only depending on the connector bottom, locating effect is not good, particularly when extracting with this socket connector winding banjo connector together, because of rear end, socket connector bottom does not have corresponding fixing member, socket connector obviously has the danger that dumps forward.The cylinder of described connector is to divide post to constitute by a pair of rubber-like, by the gap of intercolumniation existence in two fens, cylinder elasticity is inserted in the hole corresponding on the circuit board, thus fixing whole socket connector.In initial design, the post end was not established the protuberance of projection laterally in two minutes, and when it was inserted in the circuit board hole, post need not too big strain in two minutes, divided the gap of intercolumniation less relatively.But this cylinder fixing effect is poor, very easily breaks away from from circuit board.Afterwards, the structural design of protuberance occurred convexing with laterally, and fastened in circuit board bottom surface by protuberance, and make cylinder not have the danger of breaking circuit plate at minute post end.Yet because the existence of protuberance has increased the cylinder end diameter, two fens posts need inwardly to produce bigger strain and can snap in the circuit board hole, and intercolumniation just needed bigger gap in such two minutes.Excesssive gap surpasses yield limit when making the inside strain of two fens posts again easily, can't well set back, and then cause and the circuit board hole between the good power that holds of forfeiture.

The existence of above-mentioned many disadvantages and contradiction, make the align member of module type socket connector have bigger design difficulty, how fixing effect preferred positioning member to be set, really to have become a big technical barrier of industry in the module type socket connector bottom that conducting terminal links to each other with cable.

[summary of the invention]

Main purpose of the present utility model is to provide a kind of socket connector, and its align member location is firm, and fixing effect is preferable.

Another purpose of the present utility model is to provide a kind of align member of socket connector, and its elasticity is preferable, and all the time can and the circuit board hole between keep the good power that holds.

The purpose of this utility model is achieved through the following technical solutions: a kind of socket connector, and be arranged on the circuit board and and be connected with external cable or circuit board, it comprises insulating body and plurality of conductive terminals.Wherein said insulating body front end is provided with one can be for the host cavity of banjo connector grafting, described conducting terminal group is located in the above-mentioned insulating body, each terminal includes contact site that stretches in the above-mentioned host cavity and the afterbody that extends and can be connected with external cable to the insulating body rear end, insulating body has the two side that is oppositely arranged, at the above-mentioned sidewall of insulating body bottom next-door neighbour and locate each downward one near the centre position and extend first reference column, can be inserted on the circuit board in the corresponding hole, described first reference column comprises first and second minute post, the lateral surface of above-mentioned two minutes posts is the periphery of reference column, there is certain interval between the medial surface of above-mentioned two minutes posts, in above-mentioned gap, tilts to extend to form a up-narrow and down-wide lug boss at the basal surface position of second fen post of medial surface next-door neighbour of second fen post.The position that is positioned at the above-mentioned first reference column rear in insulating body bottom also downwards one extend second reference column that can match with corresponding hole on the circuit board, this second reference column is positioned on the perpendicular bisector of above-mentioned a pair of first reference column.

Compared with prior art, the utility model is by being provided with first reference column and second reference column that isosceles triangle distributes on insulating body, corresponding hole interference with printed circuit board (PCB) cooperates, the location is firm, avoid the situation that socket connector dumps forward when the banjo connector is extracted takes place, fixing effect is preferable.Moreover, branch post medial surface at first reference column is provided with lug boss, the situation that the strain of two fens posts surpasses yield limit in the time of can avoiding reference column to insert in the circuit board hole takes place, and makes reference column remain preferable elasticity, and and the circuit board hole between remain the good power that holds.
