The technical scheme of the utility model is that the utility model relates to an arrangement type contact opening detection and limiting tool, which at least comprises a positioning block, a limiting block and a protection plate; the positioning blocks and the limiting blocks form an interval distribution structure at the rear upper end of the protection plate, and a positioning block is arranged between the two limiting blocks; and a space is arranged between the positioning block and the limiting block.
The positioning block is in a trapezoidal block structure, and the external dimension of the positioning block is matched with the internal dimension of the static contact of the distributed contacts.
The limiting block is of a trapezoidal block structure, and the surface opposite to the positioning block is provided with a cambered surface; one side with the cambered surface faces the outer side of the static contact piece of the distributed contact.
The side section of the protection plate is of a block structure with a small upper part and a large lower part, the small upper part is arranged on the rear edge line of the large lower part, and the small upper part is composed of a limiting block; the positioning block, the limiting block and the protection plate are of an integrated structure.
The side section of the protection plate is of a block structure with a small upper part and a large lower part, the small upper part is arranged on the rear edge line of the large lower part, and the small upper part is composed of a limiting block; the positioning block, the limiting block and the protection plate are of a split structure.
The front end protection plate of the positioning block and the limiting block is provided with a bulge or a depression.
The utility model has the advantages that: the utility model discloses convenient to use can compromise the quiet contact piece opening size of the formula of arranging contact and detect and opening value limit function, can prevent to maintain the function that personnel touched the terminal by mistake simultaneously.
The invention will be further explained with reference to the drawings of the embodiments.
Drawings
Fig. 1 is a schematic perspective view of an embodiment of the present invention;
fig. 2 is a side view of fig. 1.
In the figure, 1, a positioning block; 2. a limiting block; 3. and (4) a protective plate.
Detailed Description
As shown in fig. 1 and 2, the utility model relates to an arrangement type contact opening detection and limiting tool, which at least comprises a positioning block 1, a limiting block 2 and a protection plate 3; the positioning blocks 1 and the limiting blocks 2 form an interval distribution structure at the rear upper end of the protection plate 3, and one positioning block 1 is arranged between the two limiting blocks 2; a space is arranged between the positioning block 1 and the limiting block 2.
The positioning block 1 is in a trapezoidal block structure, the external dimension of the positioning block is matched with the internal dimension of the static contact of the arrangement type contact, and the positioning block can be clamped into paired arrangement type contact static contact pieces to play a positioning role.
The limiting block 2 is of a trapezoidal block structure, and the surface opposite to the positioning block 1 is provided with a cambered surface; one side with a cambered surface faces the outer side of the static contact piece of the distributed contact; the static contact piece of the arrangement type contact is limited by the cambered surface shape to deform towards one side of the limiting block with the cambered surface, so that the limiting effect is achieved.
The protection plate 3 is of a block structure with a small upper section and a large lower section, the small upper section is arranged on the rear edge line of the large lower section, and the small upper section is composed of a limiting block 2; the positioning block 1, the limiting block 2 and the protection plate 3 are of an integrated structure.
The protection plate 3 is of a block structure with a small upper section and a large lower section, the small upper section is arranged on the rear edge line of the large lower section, and the small upper section is composed of a limiting block 2; the positioning block 1, the limiting block 2 and the protection plate 3 are of a split structure.
