Compact junction box

Abstract

The invention discloses a compact junction box, which comprises a junction box body (15). Binding posts (13) are arranged in the box body (15). Each binding post (13) comprises a housing (43), a wire pressing bolt (41), a spring (42), an adapting column (44) and a terminal (45), wherein the wire pressing bolt (41) and the spring (42) are arranged in the housing (43); the adapting column (44) is fixed in the housing; the terminal is riveted at the lower end of the adapting column (44); and a round threading hole (46) is formed in the top of the housing (43), and a wire is inserted into the hole. Compared with the prior art, the compact junction box has the advantages that: novel binding posts are adopted, so that the overall volume of the product is decreased, and the mounting space of a user is reduced; shell sealing rings and gaskets at the bolts are adopted, so that the whole product is endowed with a sealed waterproof function; a material for the compact junction box to contact the outside adopts a high temperature resistant, oil-proof and waterproof material, so that the antismog capability of the product is improved; and the compact junction box is additionally endowed with a high temperature resistant function, an antirust function and the waterproof function, and the service life of the junction box is prolonged.

Description

technical field [0001] The invention relates to a connection device, especially a connection device for a small portable switch. Background technique [0002] With the continuous change of communication technology, communication equipment is not only constantly updated in function, but also continuously introduces new products in terms of hardware. The binding posts in the prior art are bulky and require a large space for installation on equipment, and cannot be installed on miniaturized communication equipment. prior art binding posts such as figure 1 As shown, the binding post is operated by hand, acting on the top of the binding post to press down, and the two crimping nails in the middle are separated. After the wire is inserted, release the hand, and the spring at the lower end will rebound and press the wire. This structure is due to the manual There must be sufficient space for operation, both horizontally and vertically. In addition, the binding posts are used sepa...

AI Technical Summary

Problems solved by technology

The binding posts in the prior art are bulky and require a large space for installation on equipment, and cannot be installed on miniaturized communication equipment.

prior art binding posts such as figure 1 As shown, the binding post is operated by hand, acting on the top of the binding post to press down, and the two crimping nails in the middle are separated. After the wire is inserted, release the hand, and the spring at the lower end springs back to press the wire. This structure is due to the manual There must be enough space for operation, both horizontally and vertically. In addition, the binding posts are used separately, and each one needs to be installed and sealed with the chassis. The more installations, the more mounting holes on the box, which seriously affects the mechanical strength of the chassis. thereby affecting the quality of the entire product

Moreover, the junction box of the prior art is bulky, and the user can only use it alone

At the same time, the junction box in the prior art has no sealing structure and cannot be used in a wading environment
