Description

A kind of high current high density PCB watertight connector

Technical field

A kind of connector is the utility model is related to, specifically a kind of high current high density PCB watertight connector.

Background technology

With the continuous development of space flight and aviation product, the variation of market demand connector function.At present, the bend cutting of in the market Insulator can not mostly be dismantled using sealing note, disposable installation in printed board connector, and assembling adjustment performance is uncontrollable, into Product rate is uncontrollable, increases production cost；The locking mode of other connector is locked using elastic force or frictional force, two kinds of sides The spring of formula locking, the consumable accessory such as friction plate after long-term use, easily cause failure.

The content of the invention

For the above-mentioned deficiency of prior art, the utility model provides one kind and effectively adjustment installation accuracy, raising can produced Quality, the high current high density PCB watertight connector to increase the service life.

The technical solution adopted in the utility model is：A kind of high current high density PCB watertight connector, including plug And socket, it is characterised in that：The plug includes plug casing, welded type contact pin component, contact pin insulator, contact pin insulator lid Plate, insulator stay hook, wire harness pressing plate, locking bail, contact pin insulator and contact pin insulator cover plate are worn and are connected in plug casing, weldering The formula contact pin component of connecing, which is worn, to be connected on contact pin insulator and contact pin insulator cover plate, is passed through between contact pin insulator and contact pin insulator cover plate Insulator stay hook one end hooks connection, and the insulator stay hook other end is socketed in plug casing rear inside wall through fixing screws In fixed plate, bolt is locked with the wire harness pressing plate of crimping cable on the plug casing after fixed plate, outside the two side of plug casing Provided with the corresponding locking bail towards socket；The socket include Socket casing, hole insulator, curved formula printed board wire spring socket, absolutely Edge body back-up ring, printed board protective cover, printed board location-plate, hole insulator, which is worn, to be connected in Socket casing, the front end of hole insulator with Socket casing inwall boss is spacing, and the rear end of hole insulator and Socket casing inwall are through insulator retainer ring spacing, curved formula printed board The front end of wire spring socket, which is worn, to be connected in the insulator of hole, and the rear end bending positioning of curved formula printed board wire spring socket, which is worn, to be connected on printed board and determine On the plate of position, curved formula printed board wire spring socket coordinates printed board location-plate, Socket casing to encapsulate through printed board protective cover, Socket casing Front end outer wall is provided with the locking head of corresponding locking bail.

Further, worn between contact pin insulator and contact pin the insulator cover plate through more than two alignment pins and connect positioning.

Further, described insulator stay hook one end is provided with preceding gib head and rear grab, the contact pin insulator outer wall and Contact pin insulator cover plate outer wall is respectively equipped with the forward and backward mouth of hook, preceding gib head and the rear grab difference forward and backward mouth of hook of clasp joint.

Further, the forward and backward mouth of hook is notch or step.

Further, the preceding gib head and rear grab are towards relatively.

Further, the locking bail includes coupler body, arm-tie, locking post, crimping screw, upset pin, is passed through in the middle part of coupler body The rotatable pin joint of pin is overturn in plug casing side wall, locking post is vertically set in plug casing side wall, and locking post is divided into Post and lower prop, upper column diameter are less than lower column diameter, and through arm-tie vertical support in locking post, arm-tie is provided with front and rear at coupler body rear portion The locking slot of two connections in direction releases well width and increased successively with groove, upper column diameter, locking well width, lower column diameter is released, Crimping screw wear be connected in locking post it is non-depressed press connect coupler body.

Further, be respectively equipped with the plug casing and Socket casing the spigot seal circle that is compressed during corresponding plug together and Square cushion.

Compared with prior art, the utility model has the advantages that：Using on locking bail one end towards relative preceding gib head and Grab hooks contact pin insulator and contact pin insulator cover plate clamping afterwards, then is socketed by the locking bail other end through fixing screws The fixed installation of contact pin components is realized in the fixed plate of plug casing rear inside wall, is insulated using boss and back-up ring combination spacing hole Body realizes the fixed installation of female part in Socket casing, notes and seals without glue, in the detachable adjustment assembly precision of assembled, Yield rate is improved while Product Precision is ensured, reduces production cost；When plug, socket plug together, pulling arm-tie, which makes to wear, to be connected on Locking slot on upper prop, which shifts and makes to release groove, is pulled to upper prop position, pressure coupler body rear portion, groove card is released to lower prop, after coupler body Portion can around its middle part upset pin nail rotation make coupler body front portion open outwardly be easy to be sent into locking head, locking head be sent into after, unclamp hook Body rear portion compresses and lifted, and after coupler body rear portion is lifted, promotes arm-tie to make locking slot card to upper prop, lower prop limitation arm-tie it is descending so as to The upset of coupler body rear portion is limited, so as to realize the anterior locking with locking head of coupler body, mechanization locking mode, can effectively avoid elasticity Problem of Failure caused by the rapid wear of locking and friction lock, improves service life and practical security.
