Description

The invention relates to devices for group fixing of electrical contacts and can be used in the electrical industry.

A device for mounting electrical contacts by installing them in a sleeve is known [1] ·

The disadvantage of this device is that it does not provide reliable pinning of contacts.

Of the known devices for group fixing of electrical contacts, the device closest to that proposed by the technical entity is a device comprising bending elements installed with the possibility of simultaneous rotation around the longitudinal axis with recesses for the terminals of electrical contacts, concentrically mounted in a housing designed as a fixed sleeve. around the longitudinal axis of the sleeve, on one of the end planes of which there are recesses, and on the other - ystup interacting with a straight groove mover {2].

The disadvantage of this device is

that it is intended for group

pinning electrical contacts only

with a radial arrangement of conclusions in

an insulator and cannot be applied if the leads are located tangentially to the circle or the angular arrangement of the leads in the insulator is different, and for reliable pinning of the contacts, the leads must be turned one angle. In addition, due to the presence of residual deformation in the terminals after the contacts are fixed, additional means are needed to remove the insulator from the device with the contacts fixed.

The aim of the invention is to expand the functionality of the device and increase productivity.

FIG. 1 shows the proposed device in section, general view; in fig. 2 — section A — A of FIG. one.

A device for group fixing of electrical contacts comprises a housing 1, made in the form of a glass, in which a sleeve 2 with a protrusion 3 is installed with the possibility of rotation around a longitudinal axis. Holes are made in the bottom of the glass. In the sleeve there is a cylindrical recess, in the walls of which, grooves a are made symmetrically with the holes of the housing. Bending elements 4 are made in the form of two shoulders, one shoulder 5 of which is located in the groove and sleeve 2, and the other in the groove of the housing 1. At the free ends of the arms of the levers located in the housing grooves, recesses are made b. The location and shape of the recesses on the arms of the levers correspond to the location and shape of the terminals of the electrical contacts. The movement mechanism is made in the form of a pusher 6 with a groove in which the protrusion 3 of the sleeve 2 is located.

The number and location of holes in the housing, grooves in the sleeve and double-arm levers are determined by the number and location of electrical contacts.

The device contains a spring-loaded pin 7, in the case there is a longitudinal axial hole. Spring-loaded pin 7 is located with the possibility of axial movement in the axial holes of the housing 1 and the sleeve 2. Spring-loaded pin 7 is designed to push out of the device insulator with fixed contacts.

The device works as follows.

An insulator with dialed electrical contacts, mounted in the mandrel with the terminals facing up (not shown), is fed to the device so that the terminals of the contacts fall into the recess b of the bending elements. When this spring is compressed and the pin 7 is sunk in the axial holes of the housing 1 and the sleeve 2. When you move the pusher 6, the protrusion 3 moves into the groove of the pusher. The sleeve 2 rotates around the longitudinal axis, while the shoulders 5 levers, located in the grooves of the sleeve 2, also rotate. Wherein

at the same time, they rotate around their longitudinal axes and shoulders of the levers located in the openings of the housing, unfolding the leads of the electrical contacts placed in the recesses b. The angle of rotation of the sleeve is chosen depending on the specified angle of rotation of the terminals of the electrical contacts and determines the stroke of the pusher 6. At the end of the stroke of the pusher pin 7 under the action of the spring 8 pushes the insulator with fixed contacts. The device is reset.
