Step 1: insulating body is provided, and wherein said insulating body is provided with a slot for the connectors male seat and some accepting grooves for affixed conducting terminal;
Step 2: conducting terminal is provided;
Step 3: number of assembling steps, by conducting terminal assembling and riveting extremely in corresponding accepting groove;
In being provided, the step 2 of conducting terminal comprises the following steps:
Step 1: from the terminal material consisted of beryllium-bronze, punch forming goes out the conducting terminal of required form;
Step 2: the conducting terminal after punch forming is carried out to the quenching heat treatment operation;
Step 3: the conducting terminal after quenching heat treatment technique is carried out to electroplating work procedure, on the surface of conducting terminal, form coating.
Beneficial effect of the present invention is: the conducting terminal after punch forming carries out electroplating work procedure after quenching heat treatment again, makes its surface form coating, has strengthened abrasive resistance and mechanical strength, has improved the connection reliability of connector female seat; Simultaneously, improve the conductive contact impedance, improved conductivity, promoted the signal transmission.

Embodiment
In order to set forth thought of the present invention and purpose, below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
Please refer to Fig. 1 and Fig. 2, there is shown a kind of automobile audio connector female seat, it comprises an insulating body 1 and some conducting terminals 2, and the middle part of insulating body 1 is provided with for the slot 11 of connectors male seat and some accepting grooves for affixed conducting terminal 2 12.
As shown in Figure 3, accepting groove 12 arranges to inside from the bottom of insulating body 1 equally spacedly, and in the present embodiment, accepting groove 12 is provided with 14 pairs, lays respectively at the both sides, inside of insulating body 1, and the spacing of adjacent two accepting grooves 12 of homonymy is 1.5mm.
As shown in Figure 4 and Figure 5, furthermore, conducting terminal 12 comprises contact site 121, kink 122, fixed part 123 and weld part 124, an end connecting welding section 124 of fixed part 123, the other end connecting bending folding part 122 of fixed part 123, contact site 121 connecting bending folding parts 122.As shown in Figure 2, after conducting terminal 2 assembles with insulating body 1, contact site 121 puts in slot 11, after connector socket embeds slot 11, contact site 121 contacts with the conducting terminal of connector socket, fixed part 123 is fixed in conducting terminal 2 in accepting groove 12, and fixed part 123 is provided with hangnail, and weld part 124 stretches out from insulating body 1 bottom.
The manufacture method of this automobile audio connector female seat comprises the following steps:
Step 1: insulating body 1 is provided, and wherein insulating body 1 is provided with slot 11 and some accepting grooves 12, and insulating body 1 is by the injection mo(u)lding of PBT plastic material.
Step 2: conducting terminal 2 is provided.
Furthermore, in step 2, comprise the following steps:
Step 1: from the terminal material that the beryllium-bronze that is 0.15T by material specification forms, punch forming goes out the conducting terminal 12 of required form.
Step 2: the conducting terminal 12 after punch forming is carried out to the quenching heat treatment operation, improve the hardness of conducting terminal 12.
