Description
Technical field
The present invention relates to technical field of electric connectors, relate in particular to a kind of rectangular connector.
Background technology
Existing rectangular connector generally can be divided into non-metal shell rectangular connector and metal shell rectangular connector.The structure of metal shell rectangular connector comprises connector shell and for the dielectric member of contact is installed, dielectric member is arranged in connector shell by insulator installation reed.
Insulator installation reed generally has two kinds, a kind of is presser type location structure, be dielectric member by pressing plate and standard component (as screw, pad) etc. be fixed in connector shell, thereby the reliable contact of contact in assurance connector, this presser type structure is from designing, just determined that dielectric member and connector shell must disposable assembling successes in the factory building of connector manufacturer, then could pay user uses, when user uses, again contact is packed in connector and used, in this traditional structure, can unloading parts be all single contact unloading, when contact core number is a lot, at the scene of narrow space, install and use very difficult for what become.And if time whole connector must be pulled down again and changed the outfit with the connector maintenance of the non-exchange modular of pressing plate, waste time and energy very much.If time also need pressing plate to remove with the connector maintenance of pressing plate replaceable module formula, after changing problematic module, be reinstalled pressing plate and just can complete maintenance, the dismounting of pressing plate has also increased maintenance personal's labour intensity greatly, has reduced maintenance personal's operating efficiency.
Another kind of for exempting from presser type location structure, on connector shell, drive location notch, and then on dielectric member, be designed with hangnail structure, can guarantee that dielectric member can not deviate from due to the existence of hangnail after installation from connector shell, realize the object of fixed insulation body component, because the characteristic of macromolecule engineering plastics self makes this kind of hangnail structure have certain elasticity, utilize extraction tool that hangnail is backed down and can realize dielectric member safety from housing and take out and can not destroy any parts.But because macromolecule engineering material should meet high strength high insulation, also to meet resilient requirement, the hangnail structure certainty being arranged on dielectric member can be very not large, hangnail structure is limited useful life, after the certain number of times of unloading, exist dielectric member to fix illusive risk, the dielectric member that at this moment just need to more renew, causes the waste of cost.
Summary of the invention
The object of the present invention is to provide a kind of rectangular connector, with solve insulator mounting structure dismounting in existing rectangular connector inconvenience and useful life of short duration problem.
In order to address the above problem, the technical scheme in the present invention is:
A kind of rectangular connector, comprise that front end is the connector shell of inserted terminal and for the dielectric member of corresponding contact part is installed, in described connector shell, be provided with the rectangular inner cavity with four corner parts, described dielectric member is arranged in described rectangular inner cavity by insulator installation reed, described insulator installation reed comprises base plate and the two side wall panels being connected by bending structure one with the left and right side of described base plate, described base plate and two side wall panels form U-lag structure, described base plate is provided with front end and described base plate is wholely set, extend endwise and to the prelocalization reed of the notch direction turnover of described U-lag structure, described base plate is also provided with front end and described base plate is wholely set, end extends and turns down the rear positioning reed of direction and described prelocalization reed turnover opposite direction backwards, the front end of described insulator installation reed is provided with confined planes towards the spacing seamed edge in the place ahead, two corner parts of correspondence of described rectangular inner cavity are provided with the guide slide that the bending structure for described insulator installation reed slides from front to back and packs into, the chamber wall of described rectangular inner cavity be provided with described insulator installation reed place-limited edge side bumper only coordinate so that described insulator installation reed moves forward spacing mounting structure limited step and coordinates so that described insulator installation reed moves spacing mounting structure positioning groove backward with the rear positioning reed location of described insulator installation reed, described dielectric member is provided with described prelocalization reed location and coordinates so that described dielectric member moves spacing insulator installation reed stopper slot backward.
Described rear positioning reed is arranged on the base plate at described prelocalization reed rear.
On the insulator installation reed of described base plate both sides, be integrally formed with backward the spacing gusset of projection projection and that there is relative direction confined planes, on the chamber wall of described rectangular inner cavity, in one, turn over and coordinate to stop described insulator installation reed to turn edge in circumferentially mobile in rectangular inner cavity with the spacing gusset block of described two projections.
On the cross section perpendicular to fore-and-aft direction, the cross sectional shape of described bending structure is circular arc, the bending structure of described circular arc consists of with the outwardly projecting portion being connected with corresponding wallboard the concave section being connected with base plate, and the arcuate guide slideway of joining is kissed in being shaped as with the bending structure of described insulator installation reed of the guide slide of described rectangular inner cavity.
On the chamber wall of described rectangular inner cavity, be also provided with insulator limited step, the periphery of described dielectric member is integrally formed with described insulator limited step block and coordinates so that dielectric member moves forward spacing insulator auxiliary section.
Described spacing seamed edge consists of the leading section seamed edge of the two side wall panels of described insulator installation reed, and described mounting structure limited step is arranged at the front end of corresponding guide slide.
Beneficial effect of the present invention is: insulator installation reed utilizes the bending structure slip of its both sides to pack in the rectangular inner cavity of connector shell, when the rear positioning reed of insulator installation reed slips into mounting structure positioning groove, under the common location of mounting structure limited step, mounting structure location groove and arcuate guide slideway, insulator installation reed keeps relative fixing with connector shell; Then dielectric member is packed in rectangular inner cavity, thereby guarantee that the installation of dielectric member is reliable.Because dielectric member is located by reed and step, very convenient dismounting is arranged dividing of insulator installation reed and dielectric member simultaneously, makes the structure of prelocalization reed no longer restricted, be guaranteed the useful life of U-shaped insulator installation reed, also avoided the waste of cost.
