Description

The positioner of bayonet connector

Affiliated technical field

The utility model relates to a kind of positioner of bayonet connector, refers to especially a kind ofly can realize the adjusting play automatically, effectively solve when fastening the arm welding and the positioner of the bayonet connector of insulating body end horizontal error.

Background technology

Bayonet connector is realized electric connector between memory card and circuit board, is to belong to a kind of high precision electric connector, and its number of terminals is more, is installed on the circuit board and has relatively high expectations.Along with the computer development trend, the connector of computer-internal also dwindles thereupon, certainly will reduce and dwindle terminal density for this high precision bayonet connector, and bayonet connector mainly utilizes surface adhering technology (SMT) to be fixed in motherboard at present, if horizontal error is excessive between the solder side of connector and the motherboard pad face, then can produce connector, can't well electrically contact, strengthen the processing procedure difficulty with circuit board.

See also the known bayonet connector of structure shown in Figure 1, this bayonet connector plug socket A is provided with the docking groove A1 of plural terminals A2, plural terminals A2 is arranged in plug socket A fore-and-aft direction, plug socket A two sides are concaved with location notch A3 respectively, this location notch A3 is used for pegging graft for snap close piece B fixing, this snap close piece B has a fixed arm B1 and elastic arm B2, fixed arm B1 bends inwards in root edge and is provided with weld part B11, utilizing surperficial technology for applying to be preset on the motherboard plural terminals A2 and snap close piece weld part B11 locatees, yet, when plug socket A and snap close piece B assemble, and be installed in and form three pad faces between the terminal A2 of plug socket A, must cause between three pad faces and form horizontal error, because of then can causing welding, horizontal error the time have only firmly weld at 2 with circuit board, another the point then because of the plane not coplane degree have gap or perk, can't form good the contact with circuit board, form the cavity between solder joint and circuit board, if it is too much to add tin by force, and the closeer spacing of terminal is too small, can cause short circuit between terminal again.As seen, known bayonet connector can't guarantee with circuit board between well contact, increase processing procedure and make difficulty, cause follow-up working procedures to repeat, product uses fraction defective to increase, and further can have influence on the normal connection of this bayonet connector.

Therefore,, in fact be necessary existing technology is improved, so that the positioner that forms the bayonet connector that well contacts between a kind of and circuit board to be provided at the existing defective of above-mentioned known bayonet connector.

Summary of the invention

Main purpose of the present utility model, it is the positioner that is to provide a kind of bayonet connector, utilize a metalwork to be linked in the junction surface that fastens arm, to form unsteady adjusting play, it is good again that coplane degree with the insulating body end is obtained, and effectively solves to fasten arm when welding and the horizontal error problem between the insulating body.

The above-mentioned purpose of the present utility model and the technical scheme of dealing with problems are achieved in that a kind of positioner of bayonet connector, it is mainly by insulating body, fastening arm and metalwork constitutes, insulating body central authorities are provided with the slot of plural terminals, slot two sides are respectively equipped with holddown groove, described holddown groove is provided with the fastening arm of installation, the side plate that fits tightly inside and outside this fastening arm has, be provided with the support portion in the outside bending of interior plate root edge, the not end bending of this support portion is provided with the junction surface, two lateral bucklings at junction surface are provided with limited wall, and limited wall forms metalwork with aforementioned junction surface and engages the space; One metalwork, have last fish plate and following fish plate, form between the fish plate up and down and insert and put access slot, metalwork is connected on the engaging space that fastens arm by inserting and putting the access slot buckle, be formed with flying height between its metalwork and the junction surface, when connector was welded in the circuit board contact, flying height can realize adjusting function automatically, make when fastening the arm welding and obtain preferable coplane degree, when effectively solving snap close and closing arm and weld and the horizontal error problem of insulating body end with the insulator end.

From the above, the positioner advantage of the utility model bayonet connector is obvious: the positioner of this bayonet connector can play the fixed connector effect, can in welding process, regulate automatically in addition and fasten arm and the preferable coplane degree of insulating body end acquisition, effectively solve the horizontal error problem that fastens arm assembly welding ends and insulating body end, the scolding tin that the solution connector brings because of flatness differs connects a series of problem, thereby improve processing procedure, improve the performance of product.
