Embodiment

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however appended accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.

See also Fig. 1 and Fig. 2, be respectively the three-dimensional exploded view of the utility model supply socket and the three-dimensional combination figure of the utility model supply socket, the utility model provides a kind of supply socket, in the present embodiment, supply socket comprises two conducting terminals 10 and insulating base 20, wherein:

Conducting terminal 10 is formed in one, and conducting terminal 10 has cross-under end 11, extension 12 and guiding access 13, and cross-under end 11 is cylindric, pegs graft in order to power supply source line (not shown); Extend from an end of cross-under end 11 extension 12, and this extension 12 is vertical mutually with cross-under end 11, and this extension 12 in the form of sheets; An end of 12 extends guiding access 13 from the extension again, and guiding access 13 also in the form of sheets.

Insulating base 20, the external form that is approximate cuboid, and be plastic material, insulating base 20 is coated on the outside of conducting terminal 10 for ejection formation and part, and 11 places form inserting groove 21 at insulating base 20 corresponding cross-under ends, and two or more folders groove 22 (as shown in Figure 3) of pulling is arranged in the bottom of insulating base 20 reshaping, pull groove 22 of folder coats pull in the extension 12 outside of folder, inserting groove 21 is for the power line grafting (not shown) corresponding with supply socket, and guiding access 13 exposes to an end of insulating base 20; And the sectional area of cross-under end 11, extension 12 and guiding access 13 equates, makes conducting terminal 10 equate the stability in the time of increasing conducting terminal 10 transmission currents like this in the impedance at cross-under end 11, extension 12 and guiding access 13 places; In addition, the current strength that can bear of this supply socket is 2.5 amperes to 7 amperes.

In addition, because conducting terminal 10 is two kinds of different materials with insulating base 20, insulating base 20 direct injections and part are coated on the outside of conducting terminal 10, and can't firmly fixedly connected with conducting terminal 10, so, extension 12 offers fixing hole 121, and fixing hole 121 is for insulating base 20 ejection formations and fixedly connected insulating base 20, to increase the tightness that conducting terminal 10 is connected with insulating base 20.

See also Fig. 3, be cutaway view along 3-3 hatching among Fig. 2, the production method of this supply socket is: produce integrated conducting terminal 10 earlier, conducting terminal 10 is inserted in the mould of plastics ejection formation, again with insulating base 20 ejection formations and part coated with conductive terminal 10, insulating base 20 will form and press from both sides the groove 22 of pulling like this, and extension 12 will be contained in and press from both sides in the groove 22 of pulling, thereby makes insulating base 20 press from both sides the conducting terminal 10 of pulling.The production method of this supply socket has only two steps, that is: 1, make conducting terminal 10; 2, insulating base 20 ejection formations and part coated with conductive terminal 10.This production method is compared with the production method that five steps of needs of known supply socket are finished, and can save processing cost, assembly cost and time cost.

See also Fig. 4 and Fig. 5, be respectively the three-dimensional combination figure of another embodiment of the three-dimensional exploded view of another embodiment of the utility model supply socket and the utility model supply socket, in the present embodiment, have three conducting terminals, be respectively conducting terminal 10, conducting terminal 10 ' and conducting terminal 10 "; Conducting terminal 10 has cross-under end 11, extension 12 and guiding access 13, and extension 12 offers fixing hole 121, conducting terminal 10 ' and conducting terminal 10 " then be configured in the both sides of conducting terminal 10; Conducting terminal 10 ' has cross-under end 11 ', extension 12 ' and guiding access 13 ', and extension 12 ' is skewed and offers fixing hole 121 ' thereon; Conducting terminal 10 " have a cross-under end 11 ", extension 12 " and guiding access 13 ", and extension 12 " be skewed and offer fixing hole 121 thereon "; This embodiment with three conducting terminals, its production method is and utilizes insulating base 20 ejection formations and part to be coated on integrated conducting

terminal

10,10 ' and 10 "; therefore, various forms of supply sockets even connector all can utilize this mode to make.

Therefore, supply socket of the present utility model has following advantage:

1, is formed in one by conducting terminal 10, be different from known conducting terminal and must make earlier contact pin and guide-joining plate respectively, it is riveted mutually, the procedure of processing of the utility model supply socket is reduced to a procedure of processing by known three, can save processing cost again.

2, be coated on conducting terminal 10 outsides by insulating base 20 direct injections and part, just can finish the manufacturing of supply socket, be different from known supply socket and must earlier contact pin be plugged in insulating base, and make an end of contact pin expose to insulating base, again guide-joining plate and contact pin are located riveted joint mutually; The mode that the utility model supply socket directly utilizes insulating base 20 ejection formations and part to be coated on conducting terminal 10 outsides just can be finished the making of supply socket, can significantly save assembly cost.

3, be formed in one by conducting terminal 10, and insulating base 20 direct injections and part are coated on conducting terminal 10 outsides, only need two procedure of processings just can finish the making of supply socket, thereby improve the shortcoming that needs five steps when known supply socket is made, the cost of significantly saving time.

4, the sectional area by cross-under end 11, extension 12 and guiding access 13 equates, makes conducting terminal 10 equate the stability in the time of increasing conducting terminal 10 transmission currents in the impedance at cross-under end 11, extension 12 and guiding access 13 places.
