Description

The utility model relates to a special tool for adjusting the tightness of the contacts of electromagnetic relays of the REL type with flat contact springs.

A two-way adjustment is known for servicing contacts of electromagnetic relays, characterized in that it contains a handle located in the middle of a metal rod, mainly a rod, at the ends of which bevels are made with parallel planes at an angle to the center line of the rod, the ends of the rod are bent in one plane at 90° to the axial line lines of the rod and are directed in opposite directions; slots are made in the bent ends perpendicular to the axis of the rod. The bend forms a blade 5 mm high, 4 mm wide and (2.5-3) mm long. The bend height is 7 mm with a slot depth of 5 mm, a slot width at one end of 0.6 ⁺⁰¹ mm, at the other end 1.0 ⁺⁰¹ . The rod is made of a round rod of 40X steel. The adjustment ends are hardened to (36-42) HRC. Has an anti-corrosion coating. The handle is made of polystyrene with longitudinal stiffeners (RU 209143 U1, H01H 50/00, 02/03/2022).

The disadvantage of this technical solution is the insufficient efficiency of servicing relays of the REL type of the later generation (third, fourth) at a signaling, centralization and blocking distance (SCB). This is due to the fact that these relays have smaller dimensions, and these adjustments do not allow for high-quality maintenance of the relay.

The objective of the claimed utility model is to develop a two-way adjustment for adjusting the tightness of the contacts of electromagnetic relays with flat contact springs.

In the process of solving the problem, a technical result is achieved, which consists in increasing the efficiency of repair work.

The technical result is achieved by double-sided adjustment for servicing electromagnetic relay contacts, made of a metal plate 10 mm wide, 2.5 mm thick, on which, on opposite sides of the plate, from the central part, two bevels are made at an angle of 5° to the center line of the plate, forming parallel planes, the ends of the plate are bent 90° in opposite directions to a bend value of 8 mm, in the plane, at an angle of 12° to the center line, slots are made in the bent ends to a depth of 4 mm, a width of 0.6 mm.

The bend forms a blade 5 mm high, 4 mm wide and (2.5-3) long with a slot.

The adjustment is made of 40X steel.

The adjustment ends are hardened to (36-42) HRC.

The adjustment has an anti-corrosion coating.

The bevels of the sides are made to a length of 70 mm.

Performing adjustments with the specified parameters increases the efficiency of repair work and reduces relay maintenance time.

The two-way adjustment is made in such a way that, starting from the center to the ends, the height of the plate decreases from 10 to 6 mm.

The utility model is illustrated in the drawing, where Fig. 1 shows a general view of the two-way adjustment (two types), and Fig. 2 shows a fragment of the end of the plate with a bend.

Two-way adjustment is made of steel plate 1, width a = 10 mm, thickness b = 2.5 mm. From the center to the ends of the plate, the width of the plate decreases, i.e. There is a 1.1 bevel. at an angle of 5° to the center line of the plate. The ends 2 of the plate 1 are bent 90° in opposite directions to a bend value of 8 mm, in the plane, at an angle of 12° to the center line, in the bent ends 2.1 slots 3 are made to a depth of 4 mm, a width of 0.6 mm.

Two-way adjustment works as follows. The specialist who adjusts the tightness of the contacts visually identifies the contact pair that needs to be adjusted in the light. The selected plate is placed in the adjustment slot 3, and the plate is bent by rotating adjustment 1 relative to the center by a small amount. The adjustment is disengaged from the plate. Check the gap between the contacts. If necessary, this cycle is repeated.

The proposed two-way adjustment has ergonomic characteristics, allowing it to be easily positioned on the thin contact springs of small-sized relays. There is technical documentation for production.
