Embodiment 1

[0026] Such as Figure 4 and Figure 5 As shown, the connector protection collar of this embodiment is composed of two buckle parts 1, 2 and a wire tie 5, and one end of the wire tie 5 is divided into two ends to connect the two buckle parts 1, 2, and the other end is respectively separated The fixing ring 51 and the fixing buckle 52, when in use, the fixing buckle 52 extends into the fixing ring 51, and at the same time surrounds a component on the connector to be protected, such as a wire, so that the overall protection collar of the connector will not be scattered or lost during use; The wire tie 5 is connected in the direction perpendicular to the closing plane of the snap rings 1 and 2, and is connected to the outside of the buckle. When using the clip ring, there is no need to artificially reverse the direction of the wire tie, which is convenient to use and prevents the wire tie from breaking from the root. .

Embodiment 2

[0034] The structure of the connector protection collar of this embodiment is basically the same as that of Embodiment 1, the difference is that the ends of the clips 1 and 2 close to the wire tie are connected to each other through a connecting part, and a flexible connection method is adopted, such as a wire One end of the connection with the collar is separated from the two ends that are close to each other to connect with the buckle parts 1 and 2; the insulating plastic material of the collar itself can also be used for connection, and the other end is respectively provided with a card with the same structure as in the first embodiment. hook or slot,

Embodiment 3

[0036] The structure of the connector protection collar of this embodiment is basically the same as that of Embodiment 1, the difference is that: both ends of the buckle 1 are provided with a group of hooks with the same structure as in Embodiment 1; and the buckle 2 Both ends of each are provided with a group of card slots with the same structure as in Embodiment 1.

Abstract

The invention relate to a connector protection clipping ring which is composed of two buckling parts (1 and 2). A hook (3) and a clipping groove (4) are arranged at one end of the buckling parts, the hook (3) extends out of the buckling part (1) and is composed of a hook neck and a hook tip, and a bulge (31) extending from the hook neck is arranged on the hook tip; a groove (41) matched with the hook tip bulge (31) is arranged in the clipping groove (4), the two buckling parts (1 and 2) are clipped into a closed hollow clipping ring through the hook (3) and the clipping groove (4), a through notch (6) is arranged at the rear part of the hook tip bulge (31) on the upper edge of the buckling part (1), and through notches (7) are arranged on the clipping groove (4) and the rear part of the groove (41) on the upper edge of the buckling part (2). The design reduces the production cost of products; and the wire binding structure increases the service life of the products.

Description

technical field [0001] The invention relates to a connector protection device, in particular to a connector protection device which can be clamped on the exposed metal part of a connector for insulation protection. Background technique [0002] Used in connection devices in chemical industry, petroleum, coal, flour mills and other potentially explosive environments. In the energized working state, the mutual looseness of the connecting parts will generate sparks, so that the dust and flammable gases in the air are very easy to generate explode. In order to avoid this potential explosion hazard, a collar is specially designed for connecting devices used in potentially explosive environments to protect the connecting parts from being loosened or damaged under working conditions. [0003] figure 1 It is a kind of collar currently on the market. The collar is mainly composed of two identical semicircular collars, and hooks and slots are respectively provided on the two semici...
