Description

The conductive stud structure-improved of relay

Technical field

The utility model relates to a kind of conductive stud structure-improved of relay, refer in particular to a kind of locomotive that is applicable to activating relay and automobile power source electricity post, can make the thickness of electrode slice more unrestricted, and and electrode slice between can certain quilt lock and reach the conductive stud structure of electric connection.

Background technology

See also Fig. 1, it is a kind of known relay, this relay is to use for locomotive to activate relay, it includes a shell 10a and a cover cap 11a, this shell 10a inside is provided with the electromagnetism operating member by solenoid formations such as (figure slightly), this cover cap 11a is fixed in shell 10a top, in order to seal this shell 10a open top, this cover cap 11a inside is provided with the relay system that is made of two conductive stud 12a etc., this two conductive stud 12a runs through cover cap 11a in the upper end and stretches out outside suitable length, can be combined with pad 13a on this two conductive stud 12a, respectively has a contact site 17a who does not establish screw thread on this two conductive stud 12a, this pad 13a is the contact site 17a that is sheathed on conductive stud 12a in the tight fit mode, this contact site 17a also exposes the suitable height of pad 13a end face, this contact site 17a can cooperate the electrode slice 15a of lead 14a, and borrow nut 16a to be bolted in conductive stud 12a, be matched with electrode slice 15a (as shown in Figure 2) on the conductive stud 12a in order to locking, electrode slice 15a is folded between pad 13a and the nut 16a, and electrode slice 15a can borrow nut 16a and pad 13a and conductive stud 12a to reach electric connection, and then make this two leads 14a and relay reach electric connection, to reach the effect that activates the locomotive running.

But, above-mentioned known relay, owing to be not provided with the setting of the contact site 17a of screw thread, make relative being restricted of height of electrode slice 15a, promptly the thickness of this electrode slice 15a can not be lower than contact site 17a to expose the height of pad 13a end face too many, if electrode slice 15a is lower than certain thickness, because contact site 17a is not provided with screw thread, this nut 16a promptly can't be certain be bolted in conductive stud 12a, what make that electrode slice 15a can't be stable is locked in conductive stud 12a.

Moreover, above-mentioned known relay, this two electrode slice 15a bottom surface is face with two pad 13a end faces and contacts under desirable state, but at those pads 13a, electrode slice 15a or nut 16a when correctly locking does not have deflection, the situation that promptly has loose contact between this electrode slice 15a and the pad 13a takes place, and makes between this electrode slice 15a and the pad 13a can't certain quilt to lock and reach electric connection.

So as from the foregoing, the conductive stud of above-mentioned known relay on reality is used, obviously has inconvenience and exists with shortcoming, and can wait to be improved.

Summary of the invention

The purpose of this utility model is to propose the conductive stud structure-improved of the relay that a kind of trunk portion by conductive stud, threaded portion and pad form, it makes the thickness of electrode slice select to have the elasticity variation, also make can be certain between this electrode slice and the contact site by affixed and reach electric connection, thereby solved the existing in prior technology problem.

The technical scheme that the utility model adopted is:

This conductive stud has a trunk portion and a threaded portion, is provided with the bigger contact site of an external diameter between this trunk portion and the threaded portion, is combined with pad on this contact site, and this contact is provided with a plurality of grooves, and those groove upper ends respectively are formed with a protruding point;

Whereby, the electrode slice of lead can be placed on the contact site of this conductive stud, and utilize nut to be bolted in the threaded portion, this electrode slice is locked in conductive stud, make this electrode slice bottom surface and those protruding points form multipoint mode and contact.

Characteristics of the present utility model are: its electrode slice can be placed on the contact site of conductive stud, the thickness of electrode slice can not be subjected to the restriction that contact site exposes the pad apical side height, no matter thickness all can be placed on the contact site electrode slice, and utilize nut with electrode slice stable be locked in conductive stud, so the thickness of electrode slice is selected to have elasticity and is changed.

Next is, its electrode slice bottom surface is to form multipoint mode between the contact site with conductive stud to contact, when even pad, electrode slice or nut have deflection, still can be certain between this electrode slice and the contact site contact makes between this electrode slice and the contact site can certain quilt to lock and reach electric connection.
