The embodiment provides an armor component for a metal armored movable switch device, as shown in fig. 1-2, the armor component comprises an armor plate 1 and a connecting plug pin 3, two ends of the armor plate 1 are both provided with connecting platforms 2, and the connecting platforms 2 are provided with through holes for the plug pin 3 to pass through;

the bolt 3 comprises an inserting part 32, a first limiting part 31 and a second limiting part 33 which are respectively positioned at two ends of the inserting part 32, the first limiting part 31 comprises more than two elastic clamping jaws, and a gap is formed between every two adjacent elastic clamping jaws.

Armor 1 in this embodiment can customize or select according to the size of cubical switchboard, and the installation of armor 1 in this application adopts bolt 3 to fix adjacent armor 1, does not need the trompil also can not destroy the cabinet body on the cabinet body.

Preferably, the connection platform 2 that sets up on the adjacent armour 1 in this application can crisscross the setting from top to bottom, makes things convenient for 1 internal surface of armour and the laminating of cabinet body surface, and the surface keeps relatively level and smooth, and concrete arrangement mode technical staff in the field can select as required.

The connecting table 2 in this embodiment may be plate-shaped and disposed along the edge of the armor 1, or may be disposed along the edge of the armor 1, or if disposed along the edge of the armor 1, it is disposed in plural.

The connection platform 2 and the armor plate 1 in the embodiment are preferably integrally formed, so that the cabinet body is firmer and can be better protected.

When the armor 1 in the embodiment is installed, only the connecting platforms 2 of two adjacent armor 1 need to be lapped together, and then the plug pin 3 is inserted into the through hole in an aligning manner. When bolt 3 inserts, can press hard or beat, elasticity jack catch can contract under the pressure effect this moment, after first spacing portion 31 passes the through-hole, owing to lost the pressure of through-hole lateral wall to the jack catch, the jack catch can resume deformation to play spacing, prevent the effect that bolt 3 and armour 1 break away from.

In this embodiment, each elastic claw includes a connecting elastic sheet 311 and an inverted elastic sheet 312, one end of the connecting elastic sheet 311 is connected to the insertion portion 32, the other end of the connecting elastic sheet is connected to the inverted elastic sheet 312, the distance between the inverted elastic sheet 312 and the axis of the plug pin 3 gradually increases along the direction close to the second limiting portion 33, and the maximum distance is greater than the radius of the through hole.

Set up flip-chip shell fragment 312 in this embodiment, make things convenient for first spacing portion 31 to pass the through-hole on the one hand, flip-chip shell fragment 312 can play the effect of direction, and on the other hand avoids the elasticity jack catch atress to withdraw from the through-hole, the better spacing effect of playing.

Preferably, the connecting elastic piece 311 and the flip elastic piece 312 in this embodiment both have a certain thickness and deformability, and the specific numerical value can be determined by those skilled in the art according to the working condition.

In this embodiment, two or more elastic claws are uniformly arranged around the axis of the plug pin 3, so that the whole stress of the first limiting part 31 is relatively uniform.

In this embodiment, the second position-limiting portion 33 is connected to the inserting portion 32 through a screw.

Because the unique structure of first spacing portion 31 for it is more convenient that first spacing portion 31 passes the through-hole, nevertheless withdraw from the through-hole and hardly withdraw from the through-hole even under the prerequisite that does not harm first spacing portion 31 relatively difficult, so adopt threaded connection between spacing portion 33 of second and grafting portion 32, when needs are dismantled armor 1, only need pull down spacing portion 33 of second, then make armor 1 produce the gap under the effect of self toughness and between the cabinet body, wear out grafting portion 32 and first spacing portion 31 from the one side that is close to the cabinet body, realize the dismantlement of armor 1, make armor 1 can reuse.

In this embodiment, for convenience of installation, the second limiting portion 33 may be fixed on the inserting portion 32 in advance, so that no extra workload is generated when the armor 1 is installed. In addition, can set up spacing portion in the through-hole, can set up the spacing groove that is used for dodging spacing portion on the grafting portion 32 for when needs dismantle spacing portion 33 of second, rotate spacing portion 33 of second, grafting portion 32 can not follow the rotation under the restriction of spacing portion and spacing groove, make things convenient for the quick dismantlement of spacing portion 33 of second, of course technical staff in the field can also set up other spacing modes as the condition.

In this embodiment, the connection station 2 includes a first connection station 2 disposed at one end of the armor 1 and a second connection station 2 disposed at the other end of the armor 1, and an avoidance slot is disposed on one side of the first connection station 2 away from the second connection station 2 and/or one side of the second connection station 2 away from the first connection station 2.

In this embodiment, the connection platforms 2 at the two ends of the armor 1 may have one surface flush with the inner surface and the outer surface of the armor 1, respectively, so that the inner and outer surfaces of the whole assembled armor 1 are kept relatively smooth, and at this time, in order to prevent the first limiting portion 31 and the second limiting portion 33 from protruding out of the surface of the armor 1, the connection platforms 2 are provided with avoiding grooves.

In this embodiment, the armor 1 is a straight armor 1 or an L-shaped armor 1, where the straight armor 1 may be installed on the surface of the cabinet body, and the L-shaped armor 1 may be installed at a corner of the cabinet body.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
