Detailed Description of the Preferred Embodiments
[0021] Referring to FIGS. 2 to 8, a preferred embodiment about the receptacle of the present invention is illustrated. The receptacle includes a main body 10, a plurality of terminals 20, a connector 30 and a plurality of leads 40.
[0022] The main body 10 is made of plastics and insulating materials. An elastic element 11 is installed at a top thereof. A receiving chamber 12 with an opening at the rear end is mounted within the main body 10. Near the rear end of the receiving chamber 12 is installed with a positioning groove 14 at position with respect to the buckle 13. The front end of the main body 10 is installed with a plurality of terminal grooves 15. The terminal grooves 15 are arranged with an equal space and are installed in the main body 10. The terminal grooves 15 are communicated with the receiving chamber 12.
[0023] The terminal 20 is made of copper and other conductive material. The terminals 20 are installed in the terminal grooves 15. Each terminal 20 has a respective pierce end 21 for being electrically connected the lead 40.
[0024] The connector 30 is made of plastics and other insulated material. The rear side of the connector 30 is a hollow cover 31. The front end and rear end of the hollow cover 31 are opened for being inserted by leads 40. The front end of the connector 30 is installed with a plurality of wire grooves 32. A hollowed portion is installed between the wire grooves 32 and the hollow cover 31. The wire grooves 32 are spaced with an equal space and are installed on the hollow cover 31. The lateral wall of each wire groove 32 is opened. Each of two sides of the opening is installed with a guide tilt surface 34. The lateral side of the wire groove 32 is installed with a narrow groove 35 the width of which is slight smaller than the inner diameter of the wire groove 32. Furthermore, referring to FIG. 8, the connector 30 may has a longer length.
[0025] The lead 40 is inserted into the hollow cover 31 of the connector 30, so that the lead 40 passed through the hollow cover 31 and the hollow portion 33. Then, the lead 40 enters into a wire groove 32 through the narrow groove 35 at a lateral wall of the wire groove 32 so that the lead 40 is connected to the connector 30 in advance (referring to FIG. 3), and then the connector 30 is inserted from the rear end of the receiving chamber 12 of the main body 10. The connector 30 serves to drive the lead 40 to insert into the inner front end of the main body 10 and the connector 30 is engaged in the receiving chamber 12 of the main body 10 (referring to FIG. 10). Then the terminals 20 are pressed into the terminal grooves 15. The pierce ends 21 of the terminals 20 are used to pierce into the leads 40 so that the terminals 20 are electrically connected to the conductor in the leads 40 (referring to FIG. 6).
[0026] To cause the lead 40 to be secured within the receiving chamber 12 of the main body 10 firmly, the buckle 13 can be pushed inwards so that the buckle 13 push the respective portion of the leads 40 (referring to FIG. 7). Therefore, leads 40 may be firmly secured between the buckle 13 and the positioning groove 14. Furthermore, a part on the lead 40 with respect to the buckle 13 and the positioning groove 14 is deformed so that the lead 40 does not release from the main body 10 and the connector 30.
[0027] In the present invention, the lead 40 is connected to the connector 30 in advance since the lead 40 is connected to the connector 30 out of the main body 10. Furthermore, the lateral wall of the wire groove 32 of the connector 30 has an opens and are installed with guide tilt surfaces 34, therefore, the lead 40 may be placed in the wire groove 32 from the opening at the lateral wall of the wire groove 32. Then, the connector 30 drives the lead 40 to insert into the main body 10 so as to be electrically connected to the terminal 20. By the special design of the present invention, the assembly and operation are easy with less labor and time so that the receptacle can be assembled successfully, and thus the manufacturing cost is reduced effectively and thus is economical. Furthermore, the opening at the lateral wall of the wire groove 32 is installed with a narrow groove 35. The width of the narrow grove is slightly smaller than the inner diameter of the wire groove 32 and the outer diameter of the lead 40. Therefore, after the lead 40 is placed in the wire groove 32, the lead 40 is prevented from released from the wire groove 32.
[0028] Moreover, referring to FIGS. 9 and 10, the wire grooves 32 at the front end of the connector 30 may be designed as a round hole. Only the front end and rear end are formed with openings. Therefore, the leads 40 are inserted into the wire grooves 32 from the rear end of the wire grooves 32 so that the leads 40 are connected to the connector 30 in advance. Then, the connector 30 is inserted from the rear end of the receiving chamber 12 of the main body 10 so that the connector 30 is buckled and fixed to the receiving chamber 12 of the main body 10. Then, the terminals 20 are pressed into the terminal grooves 15. The pierce ends 21 of the terminals 20 pierce into the leads 40 and thus, the terminals 20 are electrically connected to the inner conductor of the leads 40.
[0029] Therefore, the present invention has improved the prior art receptacle. In the prior art, the leads are inserted from the rear end so that the leads are inserted into the grooves in the connector. Since the connector is fixed in the inner deep portion of the main body and the leads are made of slender and soft material. It is very hard to align the lead and the wire groove in the connector. As a result, the assembly work is inconvenient. However, this prior art defect has been improved by the present invention.
[0030] Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
