Abstract
A connector includes an insulation body having a recess defined in the first end thereof and a protrusion extends from the inner end of the recess to form an annular gap between the inner periphery of the recess and the protrusion. The protrusion has a connection hole defined therethrough and a shoulder is formed in the connection hole. A passage is defined in the second end of the insulation body and communicates with the connection hole. A conductive member is inserted into the connection hole and the passage. Multiple flexible plates extend inclinedly from the outer periphery of the conductive member and are engaged with the shoulder. The body is easily removed from the mold and the conductive member is securely connected to the insulation body.
Description
- The present invention relates to a connector, and more particularly, to a connector securely combined with the electric cable.
- A conventional connector is shown in
Figs. 1 and2 , and generally includes aninsulation body 10, acollar 11 and aterminal 12, wherein theinsulation body 10 has arecess 13 defined in the rear end thereof and apassage 14 defined in the front end thereof. Aconnection hole 15 is located in communication between therecess 13 and thepassage 14. An enlarged radial groove is formed in the inside of theconnection hole 15 so as to form ashoulder 16. Thecollar 11 is located in theconnection hole 15 and has multipleflexible plates 17 extending inclinedly at the rear end thereof so as to be engaged with theshoulder 16. Multipleresilient plates 18 extend from a periphery of thecollar 11 and toward the front end of thecollar 11. Theterminal 12 extends through the collar and inserted into thepassage 14. Theterminal 12 has multipleengaging plates 19 extending inclinedly from the periphery thereof and toward the rear end of theterminal 12 so that theengaging plates 19 are engaged with theresilient plates 18. - However, the inner diameter of the
connection hole 15 is slightly larger than that of thepassage 14, and theshoulder 16 is directly formed on the inside of theconnection hole 15, so that when theinsulation body 10 is made by way of plastic injection molding, it is difficult to removed from the mold. The inside of the enlarged groove that forms theshoulder 16 is easily damaged and fails to position thecollar 11. In order to easily remove theinsulation body 10 from the mold, the manufacturers tend to make theshoulder 16 to protrude a limited radial thickness from the inside of theconnection hole 15. Nevertheless, thethin shoulder 16 cannot firmly position thecollar 11 and theterminal 12 is easily disengaged from theinsulation body 10. Furthermore, because theshoulder 16 is directly formed on the wall of theconnection hole 15, the thick wall of theinsulation body 10 shrinks when the molding process is completely and theconnection hole 15 and theshoulder 16 deform. Thecollar 11 is either difficult to be installed in theconnection hole 15 or theflexible plates 17 of thecollar 11 cannot be engaged with theshoulder 16. - The present invention intends to provide a connector wherein the insulation body is easily manufactured and the collar is firmly connected to the insulation body.
- The present invention relates to a connector and comprises an insulation body having a recess defined in the first end thereof and a protrusion extends from the inner end of the recess to form an annular gap between the inner periphery of the recess and the protrusion such that the protrusion is expandable radially and outward. The protrusion has a connection hole defined therethrough and an enlarged groove is defined in a periphery of the connection hole so as to form a shoulder. A passage is defined in the second end of the insulation body and communicates with the connection hole. The inner diameter of the passage is smaller than that of the connection hole. A conductive member is inserted into the connection hole and the passage. Multiple flexible plates extend inclinedly from the outer periphery of the conductive member and are engaged with the shoulder.
- In the invention, the conductive member can be a terminal or a combination of a collar and a terminal. The collar is located in the connection hole and the flexible plates extend inclinedly from the first end of the collar. Multiple resilient plates extend inclinedly from the periphery of the collar and toward the second end of the collar. The terminal has multiple engaging plates extending inclinedly from the periphery thereof and toward the first end of the terminal. When the terminal extends through the collar, the engaging plates are engaged with the resilient plates of the collar.
- By the annular gap, the protrusion is expandable and can return to the initial position, so that the insulation body can easily removed from the mold by the adjustment of the protrusion. Also, a deeper enlarged groove can be made so that the flexible plates on the conductive member are firmly engaged with the shoulder. The annular gap and the connection hole have thinner wall which shrinks slightly so that the conductive member can easily be positioned and engaged within the connection hole.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
