Abstract

The utility model relates to a spring pin, in particular to a novel spring pin for V-shaped insulator strings. The novel spring pin is characterized in that an opening section (1) and a bending section (2) are included, and the bending section (2) is 1.5 mm to 2.5 mm higher than the opening section (1). The trial proves that the spring pin provided by the utility model can still work reliably under the wind action of 30 miles per second, and has low possibility of deformation and falling-off.

Description

Novel V-type insulator string spring catch

Technical field

The utility model relates to a kind of spring catch, especially novel V-type insulator string spring catch.

Background technology

At bad weather, especially under the influence of strong wind weather, the accident that insulator string breaks away from might appear in V-type insulator string commonly used in the power circuit, if the V-type insulator string comes off and is not in time found, this moment, lead only had 1.8 meters apart from the minimum range of backguy, under windage, very likely body of the tower discharge is caused tripping operation, seriously influence thereby bring to operation of power networks.And facts have proved, thereby the reason that causes insulator string to break away from mainly is a spring catch to be extruded distortion and to come off and cause.

The utility model content

The purpose of this utility model provides a kind of novel V-type insulator string spring catch, and it is also not yielding coming off under the large wind effect, thus the accident that can effectively avoid insulator string to break away from.

A kind of novel V-type insulator string spring catch, its special feature is, is made up of open section and bending section, wherein the high 1.5-2.5mm of aspect ratio open section of bending section.

Wherein the thickness of open section and bending section is 2mm.

Wherein open section is one section in opening part outermost 15mm.

Further, wherein the height of whole open section is all identical, and the height of whole bending section is also all identical.

Through probationary certificate, spring catch of the present utility model still can reliably working under the wind-force effect of 30m/s, can not be out of shape more and can come off.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the left view of Fig. 1.

Embodiment

As shown in Figure 1, the difference of the utility model spring catch and conventional springs pin is as follows:

1, as shown in Figure 1, integral thickness (referring to horizontal direction among Fig. 1) increases 0.5mm, reaches 2mm to increase elasticity;

2, as shown in Figure 2, front opening section 1 height (referring to horizontal direction among Fig. 2) for 9mm with traditional consistent, locate back (being bending section 2) at the 15mm (referring to vertical direction among Fig. 2) of distance front opening section 1 and form the high platform of 1.5-2.5mm (specifically can adopt 2mm to be advisable), make bending section 2 height (referring to horizontal direction among Fig. 2) in rear portion reach 11mm.And the high platform of this 1.5-2.5mm can prevent that spring catch is extruded by the osculum place of porcelain vase ball-and-socket, and rear portion bending section 2 highly is increased to 11mm can also effectively prevent excessive wear.
