Description

The utility model relates to instrumentation and is a device for installing a tape contact spring on a sealed outlet and subsequent adjustment.

A known method of mounting springs using standard plumbing tools or tools for general and special purposes, such as mounting awl OST 92-2091-85 or the like, various types of tweezers.

The disadvantages of this method are the difficulty of manipulation and the possibility of damage to the mating surfaces of the spring and the sealed output. Subsequent adjustment of the spring is also carried out with tweezers or a special key with a tip in the form of a sleeve with a groove. Consequently, installation in this way requires a relatively higher qualification of the working personnel and is accompanied by large time and material costs.

A tool is known for inserting a spiral spring insert without a driver, at least the leading end part of which is formed from a screw shaft and a rotary gripper, equipped with a gripping section for fastening with a recess of the end spring section of a spiral spring insert without a driver, screwed onto a screw shaft, and for installing a rotary of the gripper, a groove is made in the core with a predetermined length for attaching the rotary gripper in the axial direction of the core, while the rotary gripper has an elastic connection element, one end of which is fixed in the groove for attaching the rotary gripper, and the other end is attached to the gripping section with the possibility of moving it outward in radial direction of the screw shaft in such a way that the engaging section of the gripping section is elastically engaged with the recess of the end spring section (RF Patent No. 2556259, IPC V25V 27/30, 07/10/2015). This technical solution is taken as a prototype.

The disadvantage of the above utility model is the impossibility of its application for mounting tape contact springs.

The task that the device solves is to simplify the manipulation of the mounted spring.

The technical result of the utility model is to facilitate installation and reduce the risk of damage to the mounted parts.

The technical result is achieved by the fact that the device for mounting a tape contact spring on a sealed outlet has a body with a tip in the form of a sleeve with a groove on one side and a through end hole on the other. A rod is installed in the housing, which has the possibility of axial movement inside the housing, and a locking screw that limits the movement of the rod. One end of the rod protrudes from the housing; at the end of the second end of the rod, a pin is fixed, having a lead-in chamfer and passing inside the tip sleeve.

The essence of the utility model is illustrated by drawings, where

1 - fixture body;

1.1, 1.2, 1.3 - body bushings;

2 - rod;

3 - pin with lead-in chamfer;

4 - locking screw;

5 - contact spring;

6 - sealed output.

In FIG. 1 shows a general view and section of the device.

In FIG. 2 shows a drawing of mounted springs.

In FIG. 3-5 shows the operation of the device:

- in Fig. 3 shows a device in which a spring is installed, resting its end against the working surface of the table;

- in Fig. 4 shows a fixture with a pin inserted into the spring loop;

- in Fig. 5 shows a fixture with a spring mounted on a sealed output of the product.

A device for mounting a tape contact spring is a prefabricated body 1, made in the form of three sequentially pressed bushings 1.1, 1.2, 1.3; there is a groove on the bushing 1.3. Inside the housing, a rod 2 is installed with a pin 3 fixed in it with a lead-in chamfer, which has the possibility of axial movement inside the housing when pressing on the end, which is limited by the locking screw 4.

Due to the tight fit required for adjustment, the spring seat diameter loop is approximately 15% smaller than the sealed terminal diameter and ranges from 0.5 mm to 0.7 mm.

The device works as follows.

To carry out the installation, the contact spring 5 (Fig. 2) is placed in a loop in the sleeve 1.3 of the device so that the free part of the spring is in the groove of the sleeve 1.3, as shown in Fig. 3. Then, resting the end of the spring loop in the working surface of the table, by pressing on the protruding part of the rod 2 of the device until the rod stops in the limit screw 4, the pin 3 is inserted inside the spring loop, as shown in Fig. 4. The fixed contact spring is transferred to the corresponding pressure seal with the creation of a small axial pressure on the body of the device until the pressure seal completely pushes the pin out of the spring loop, fixed on the pressure seal; the result is shown in Fig. 5. Adjustment of the contact spring is carried out by turning the fixture around the output axis.

Claims (1)

A device for mounting a tape contact spring on a sealed terminal, comprising a housing with a tip, characterized in that the tip is made in the form of a sleeve with a groove, a rod is installed inside the housing, capable of axial movement inside the housing, one end of which protrudes from the housing, and a locking screw, limiting the movement of the rod, while at the end of the second end of the rod a pin is fixed, having a lead-in chamfer and passing inside the tip sleeve.
