An object of the utility model is to provide a contact combination die to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the contact combined rivet comprises a pressing rod and a rivet head, wherein the pressing rod is sleeved on the outer side of the bottom of the rivet head, a static contact is mounted at the bottom of the pressing rod, the upper end of the static contact penetrates through the pressing rod and the rivet head and extends to the outside, and a contact matched with the lower end of the rivet head is fixedly mounted at the lower end of the static contact.

As a further technical solution of the present invention: and the bottom of the pressure lever is provided with a rivet hole for the rivet head to pass through.

As a further technical solution of the present invention: a first abdicating hole matched with the static contact is formed in the pressing rod, and a second abdicating hole matched with the static contact is formed in the rivet head.

As the utility model discloses a further technical scheme again: the pressing rod is connected with the rivet head through a fixing pin, and pin holes matched with the fixing pin are formed in the pressing rod and the rivet head.

As the utility model discloses a further technical scheme again: the riveting head is characterized in that a spring groove is formed in the outer portion of the riveting head, a spring is installed in the spring groove, the spring sleeve is arranged on the outer portion of the riveting head, and the lower end of the spring is connected with the pressing rod.

Compared with the prior art, the beneficial effects of the utility model are that: the spring and the pressure rod are sleeved at the bottom of the rivet head to be matched, so that the phenomenon of deflection is avoided when the rivet head is riveted with a static contact, the performance of the switch after installation is improved, and the assembly efficiency is high.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

The contact combination rivet head shown in fig. 1, 2 and 3 comprises a pressure lever 1 and a rivet head 2, wherein the pressure lever 1 is sleeved outside the bottom of the rivet head 2, and is specifically in sliding connection, namely the rivet head 2 can slide up and down in the pressure lever 1; the static contact 5 is installed at the bottom of the pressure rod 1, the upper end of the static contact 5 penetrates through the pressure rod 1 and the rivet head 2 and extends to the outside, the contact 6 matched with the lower end of the rivet head 2 is fixedly installed at the lower end of the static contact 5, namely the static contact 5 is fixed through the pressure rod 1, then the rivet head 2 is pressed down to be riveted with the contact 6 on the static contact 5, assembly is completed, the phenomenon that the contact 6 is inclined when the switch is installed is avoided, and therefore various performances of the switch are improved, and installation efficiency is high.

Furthermore, the bottom of the pressure lever 1 is provided with a riveting hole for the rivet head 2 to pass through, so that the rivet head 2 is convenient to rivet with the contact 6 through the riveting hole.

Furthermore, a first yielding hole matched with the static contact 5 is formed in the pressure lever 1, a second yielding hole matched with the static contact 5 is formed in the rivet head 2, the static contact 5 is made of elastic metal, the upper end of the static contact penetrates through the two yielding holes, and the lower end of the static contact is pressed by the pressure lever 1, so that the stability during riveting is improved, and the riveting effect is good.

Example 2

This embodiment is further optimized on embodiment 1's basis, depression bar 1 links to each other with die 2 through fixed pin 4, all seted up on depression bar 1 and the die 2 with fixed pin 4 matched with pinhole, install after accomplishing through inserting fixed pin 4 in the pinhole with depression bar 1 and die 2 fixed, constitute wholly.

Further, a spring groove is further formed in the outer portion of the rivet head 2, a spring 3 is installed in the spring groove, the spring 3 is sleeved on the outer portion of the rivet head 2, the lower end of the spring 3 is connected with the pressing rod 1, and by arranging the spring 3, when the rivet head 2 is pressed down, the spring 3 applies force to the pressing rod 1, so that the pressing rod 1 fixes the static contact 5, stability during riveting is guaranteed, and deflection is avoided.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
