specific Embodiment 1

[0040] Specific embodiment 1 of the duckbill contact of the present invention, the duckbill contact in this embodiment is a static contact fixed in the contact box of the switch cabinet for matching with the handcart. Such as figure 1 and figure 2 As shown, the duckbill contact includes a base 1 on which a contact support 2 is rotatably mounted, and a bracket 31 is swayably mounted on the contact support 2 . The rotation axis of the contact support 2 relative to the base 1 and the swing axis of the bracket 31 relative to the contact support 2 are perpendicular to each other, and the swing axis of the support 31 relative to the contact support 2 and the insertion of the duckbill contact Direction is vertical. A first splint 32 and a second splint 33 are swingably mounted on the bracket 31, and both the first splint 32 and the second splint 33 are conductively connected with the contact support 2, and the contact support 2 is fastened with the end of the external electrical c...

specific Embodiment 2

[0055] The specific embodiment 2 of the duckbill contact of the present invention, the difference between the duckbill contact in this embodiment and the above-mentioned specific embodiment 1 of the duckbill contact is only that: directly between the first splint and The contact fingers are directly processed on the second plywood, which increases the cost compared with the installation of the watch strap contacts, and is not as stable as the structure of the watch strap contacts, but the conductivity is better.

specific Embodiment 3

[0056] The specific embodiment 3 of the duckbill contact of the present invention, the difference between the duckbill contact in this embodiment and the specific embodiment 1 of the above-mentioned duckbill contact is only that the contact in this embodiment The support and the base are of an integrated structure.

Abstract

The invention relates to the field of contacts, in particular to a duckbilled contact and a switch device with the same. The duckbilled contact comprises a support and an elasticity keeping structure,a first clamping plate and a second clamping plate are assembled on the support in a swinging manner, a swinging axis of the first clamping plate is parallel to that of the second clamping plate, inserting connection structures for matching with adaptive contacts in an inserted manner are enclosed at one end of the first clamping plate and one end of the second clamping plate leaving the support,and the first clamping plate and the second clamping plate approach each other by the elasticity keeping structure. The first clamping plate and the second clamping plate are assembled on the supportin a swinging manner, the first clamping plate and the second clamping plate of the duckbilled contact can swing in the inserting connection process of the duckbilled contact and the adaptive contacts, high assembly errors are matched, and the duckbilled contact solves the problem that contact is poor as low errors are allowed when an existing duckbilled contact is matched with the adaptive contacts.

Description

technical field [0001] The invention relates to the field of contacts, in particular to a duckbill contact and a switchgear using the same. Background technique [0002] The commonly used duckbill contact is composed of multiple contact fingers, supported by a frame inside, and the multi-piece contact fingers are tensioned by springs. This kind of contact is rarely used in switch cabinets, and its structure is simple, but during the insertion process The allowable margin of error is limited. For example, a Chinese patent with the authorized announcement number CN202759181U and the authorized announcement date of 2013.02.27 discloses a duckbill type movable contact, which includes a handcart contact arm. The front end of the handcart contact arm is provided with a mounting hole, and the upper and lower sides of the mounting hole There are two contact copper medals, one of the contact copper bars is provided with a contact fixing pad on the outside, and a first disc-shaped co...
