Abstract
The invention relates to an electric connector. The electric connector comprises a shell and an insulator which is thrust forwards and inserted into the connector shell, a locating snap ring is arranged between the connector shell and the insulator and comprises an annular base body, a center hole of the annular base body is a stepped hole with a big front part and a small rear part, the step surface of the stepped hole and a locating surface arranged on the insulator are in thrusting matched, a blocking platform is arranged on an outer side surface of the front end of the annular base body, the blocking platform and an axial locating surface arranged on the inner wall of the connector shell are blocked and connected through backwards anti-stopping. In the electric connector, the insulator is fixed by the locating snap ring, because the wall of the annular base body of the locating snap ring is very thin, the height of the blocking platform arranged on the annular base body is small, the locating snap ring can be fixed only by arranging the locating surface with a smaller radial size on the connector shell, thereby even if the wall of the connector shell is very thin, the insulator can be also fixed by using the locating snap ring, and the locating snap ring is also suitable for fixing the insulator in miniaturized and high density connectors.
Description
Technical field
The present invention relates to a kind of electric connector.
Background technology
At present, the fixed form of insulator and connector shell mainly contains two kinds in connector industry: a kind of mode is to adopt gluing mode that insulator is bonded in the connector shell, and another kind of mode is that jump ring is installed on insulator in the connector shell in adopting.Adopt gluing mode because the difference of glue consumption can cause bonding consistency poor, and adopt gluing mode to need certain setting time, cause the production time longer, in addition, adopt gluing mode also to be not easy to the quality of checking that insulator is fixing.Adopt the mode of clamping need on connector shell, offer the jump ring groove, if offer the jump ring groove on the housing again under the situation that the wall thickness of connector shell approaches, therefore adopt the mode of interior jump ring clamping to fix insulator with regard to being not suitable for, also have the connector of small-sized high density also to be not suitable for adopting the mode of jump ring that insulator is fixed in the connector shell.
Summary of the invention
The purpose of this invention is to provide a kind of electric connector, in order to improve the fixed form of insulator in the existing electric connector.
For achieving the above object, the present invention adopts following technical scheme: a kind of electric connector, comprise connector shell and forward thrust be plugged in insulator in the connector shell, be provided with the location snap ring between described connector shell and the insulator, this location snap ring comprises the ring-type matrix, the centre bore of this ring-type matrix is pre-large post-small shoulder hole, the locating surface thrust that is provided with on the cascaded surface of this shoulder hole and the insulator cooperates, the lateral surface of described ring-type matrix front end is provided with Ka Tai, and the inwall of described Ka Tai and connector shell is provided with axial locating surface retaining clamping backward.
The place ahead of described location snap ring is provided with the bond layer between insulator and connector shell.
At least be provided with two Ka Tai on the described ring-type matrix, each Ka Tai circumferentially evenly is provided with at interval along the ring-type matrix, is provided with axially extended glue groove between per two adjacent card platforms.
The front end of described each Ka Tai is provided with chamfering.
The arranged outside in described connector shell stage casing has mounting panel.
The front end of this electric connector is provided with the grafting chamber, and the bottom in grafting chamber is provided with the end sealing ring.
Electric connector of the present invention, adopt the location snap ring that insulator and connector shell are fixed, the wall thickness of the ring-type matrix of location snap ring is very thin, the height of the Ka Tai that is provided with on the ring-type matrix also lower (generally about 0.3mm), so only need can be used for fixing the installing and locating snap ring in that the less axial locating surface of radial dimension (generally about 0.3mm) is set on the connector shell, and then insulator is fixed in the connector shell, therefore, even the thin location snap ring that also can adopt of the wall thickness of connector shell carries out the fixed insulation body, equally also be applicable to the fixing of insulator in the small-sized high density connector.Adopt the structure of location snap ring to fix insulator,, therefore can guarantee the consistency of product quality because the manufacturing of axial locating surface on the connector shell and location snap ring can reach the requirement of machining accuracy easily.
Bond layer between connector shell and the insulator has been eliminated the gap between them, has played the effect of fixed insulation body.Between per two card platforms of location snap ring, be provided with axial glue groove, when the installing and locating snap ring, a part of glue between connector shell and the insulator can enter in the glue groove, the situation that can't the location snap ring when having prevented to smear between connector shell and the insulator too much bonding agent be in place takes place, in addition, bonding agent enters into the effect of also having played the stationary positioned snap ring in the glue groove.Fixed structure among the present invention has adopted double fixed mode bonding and location snap ring clamping, has improved reliability of fixation between insulator and the connector shell.
