Description
Technical field
The present invention relates to a kind of electric connector.
Background technology
Connector is the electric connecting part that electrical connection art is in daily use, and is coordinated by the connection that can dismantle flexibly, can make the function realizing between different wire harness being electrically connected.But in the wire harness electric connector of more existing electric connectors especially automobile; usually can because service time is long or use under the environment of vibration of being everlasting; the female terminal that electric connector usually can occur is connected with male terminal and loosens and cause the situation of loose contact, and then causes vehicular electrical appliance cisco unity malfunction.
A kind of electric connector of prior art, normally female terminal and male terminal contact site are set to the shape of elastic contact blade, produce certain elastic force by the strain of elastic contact blade self and elastic force acted on male terminal surface, thus making described elastic contact blade and described male terminal surface have certain extruding force; But, owing to using under long vibration environment, the yield strength of elastic contact blade easily reduces, thus the pressure acted on male terminal can reduce, elastic contact blade and male terminal are easy to electrical contact and do not go up, thus easily cause the situation of female terminal and male terminal loose contact, electric connector was easily lost efficacy.
Summary of the invention
Use under the environment of vibration due to long for described above, female terminal and male terminal easily come in contact bad situation, the invention provides a kind of electric connector, it can make female terminal and male terminal under long vibration environment, use the situation that loose contact is less likely to occur.
A kind of electric connector of the present invention, comprise sheath, be inserted in the male terminal in described sheath one end and be inserted in the described sheath other end and can the female terminal that coordinates of electrical contact with described male terminal, the contact site that described female terminal contacts with described male terminal is at least two elastic contact blades, described sheath is also installed with to push up with described elastic contact blade opposite position place and buckles, after described male terminal coordinates with described female terminal electrical contact, the outer surface of described elastic contact blade is detained inner surface and is mutually extruded to contact with described top and coordinate, another opposing inner surface of described elastic contact blade mutually extrudes to contact with described male terminal outer surface and coordinates.
Further, described sheath has a container cavity, and described sheath is provided with described elastic contact blade opposite position place and along the horizontal direction of described sheath the installing hole be communicated with in described container cavity, and described top button is installed in described installing hole.
Further, described top button comprises the base portion be sticked in described installing hole and the lug boss extended in described container cavity chamber along the inner surface of described base portion, and described lug boss and described elastic contact blade mutually extrude to contact and coordinate.
Further, the sidewall of a pair symmetry of described base portion is respectively arranged with an anti-back button, described anti-back button and described installing hole cooperatively interact and keep described top button bit in described installing hole.
Further, described elastic contact blade has an aduncate bend, and the end face away from described base portion on described lug boss is resisted against on the outer surface of described bend.
Further, the surface described lug boss contacted with described bend is the curved surface suitable with described bend outer surface.
Further, described sheath comprises the female terminal installing rack be arranged in the container cavity installing described female terminal one end, and described female terminal is installed on described female terminal installing rack.
Further, described female terminal installing rack is provided with a through hole with corresponding position, described elastic contact blade position, described top button mutually to extrude with described elastic contact blade through described through hole and coordinates.
Further, described female terminal installing rack is sticked in the container cavity of described sheath by buckle.
Further, described elastic contact blade is two, and comprise the first elastic contact blade positioned opposite to each other and the second elastic contact blade, described top button is two, and comprise the first top be arranged on relative to one another on described sheath and buckle and second push up and buckle, described first top button is arranged at and described first elastic contact blade opposite position place, described second top button is arranged at and described second elastic contact blade opposite position place, after described male terminal coordinates with described female terminal electrical contact, described first top button mutually extrudes to contact with described first elastic contact blade and coordinates, described second top button mutually extrudes to contact with described second elastic contact blade and coordinates, described male terminal is between described first elastic contact blade and described second elastic contact blade, and mutually extrude with described first elastic contact blade and the second elastic contact blade respectively and coordinate.
Further, ultimate range between the two sides that described male terminal contacts with described first elastic contact blade and the second elastic contact blade is respectively h, described first top button and described second pushes up button and is installed to before in installing hole, minimum range between described first elastic contact blade and described second elastic contact blade is d, and described d is greater than described h.
The invention has the beneficial effects as follows that fixedly mounting top by position corresponding with elastic contact blade on sheath buckles, and coordinate by the inner surface of top button is extruded mutually with the outer surface of elastic contact blade, thus make top button provide extruding force to described elastic contact blade, and by another opposing inner surface of described elastic contact blade is coordinated with described male terminal exterior surface, thus described top button can be converted into the extruding force of described elastic contact blade to described male terminal to the extruding force of described elastic contact blade, and then strengthen elastic contact blade to the pressure of male terminal; Thus when using under long vibration environment, the yield strength effectively decreased due to elastic contact blade reduces and situation that the elastic contact blade that causes does not contact with male terminal occurs.And then the situation effectively decreasing female terminal and male terminal loose contact occurs, make electric connector be not easy to lose efficacy, improve the reliability of the connection of electric connector, and then improve the quality of electric connector.
