Abstract

The utility model provides a quick plug for an electric terminal box, comprising an inserted link. The quick plug for the electric terminal box is characterized in that: the inserted link is provided with a spring plate which is gradually protruded backwards from the front end of the inserted link and is extended to the tail end of the inserted link; a contact surface with the hole wall of a terminal box on the spring plate is provided with ratchets layer by layer. Because the quick plug adopts the structure, the ratchets of the spring plate are used to replace an elastic inverted hook to eliminate a clearance between the elastic inverted hook and the tail end of the inserted link, thereby reducing the precision requirement to the clearance between the elastic inverted hook and the tail end of the inserted link, and simplifying the processing process to reduce the processing cost; meanwhile, the quick plug for the electric terminal box does not have requirement on the wall thickness of the terminal box; when the quick plug for the electric terminal box is inserted into the terminal box, the ratchets on the spring plate can buckle the wall of the terminal box, because the spring plate is gradually protruded backwards from the front end of the inserted link and is extended to the tail end of the inserted link, when the spring plate is inserted deeper, the connection between the spring plate and the inserted link is fastener, thereby a firm connection is formed.

Description

The electrical junction box quick plug

Technical field

The utility model relates to the electrical junction box quick plug, mainly is used in the connection of various circuits being introduced terminal box.

Background technology

In various wiring operation process, because lead, optical fiber etc. have certain length, when laying certain-length or needing separated time, need will carry out in the introducing terminal boxes such as lead, optical fiber, introducing joint commonly used is to be inserted in the terminal box, is fixed this connected mode inconvenient operation again by the Luo cap, especially when terminal box hour, ease for operation is more not outstanding for it.So, a kind of quick plug has appearred on the market, and it is that front end increases an elasticity hook on existing inserted link, and the elasticity hook is protruding gradually to the back-end by the inserted link front end, and the distance between elasticity hook and the inserted link end is corresponding with the terminal box wall thickness.When it inserted terminal box, the elasticity hook was oppressed, and inserted link inserts smoothly, and after the insertion, the elasticity hook is upspring, and hooks the terminal box inwall, thereby reaches purpose of connecting.This quick plug requires the machining accuracy height, when the terminal box wall thickness less than between elasticity hook and the inserted link end apart from the time will make connect loosening, when the terminal box wall thickness greater than between elasticity hook and the inserted link end apart from the time will make the elasticity hook can not hook the terminal box inwall, thereby do not reach purpose of connecting, and its versatility is also lower.

The utility model content

The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, provide simple in structure, manufacturing cost is lower, easy to operate, connection stability good, the related little electrical junction box quick plug with the terminal box wall thickness of versatility.

The technical solution of the utility model is: the electrical junction box quick plug, comprise inserted link, it is characterized in that on inserted link being provided with by inserted link front end projection and extend to the shell fragment of inserted link end gradually backward, be provided with ratchet layer by layer with terminal box hole wall contact-making surface on the shell fragment.

Described shell fragment is connected with inserted link by the shell fragment matrix, and the shell fragment matrix is a cylindrical snare, and its internal diameter is corresponding with the inserted link external diameter, and shell fragment is arranged on the shell fragment outer surface of matrix.

Described shell fragment matrix is curled into the cylindrical snare of open-ended by side's bar shaped elastic sheet.

Described shell fragment matrix and inserted link can adopt the connected mode of welding, also can adopt on the inserted link outer surface by the inserted link end offer radially that a width is corresponding with the shell fragment width, the degree of depth and shell fragment thickness corresponding groove, with the shell fragment setting wherein.

The utility model is owing to adopted said structure, replaced the elasticity hook with the ratchet on the shell fragment, eliminated the gap between elasticity hook and the inserted link end, thereby reduced because of the gap precision requirement between elasticity hook and the inserted link end, simplified processing technology, thereby reduced processing cost, simultaneously, butted line box wall thickness does not require yet, when the utility model electrical junction box quick plug inserted terminal box, the ratchet on the shell fragment will fasten the terminal box wall, because of shell fragment is by inserted link front end projection and extend to the inserted link end gradually backward, insert dark more will be tight more, thereby form firm connection.That the utility model compared with prior art has is simple in structure, manufacturing cost is lower, easy to operate, connection stability good, the advantage of highly versatile.

Concrete case study on implementation

The utility model is described in further detail below in conjunction with accompanying drawing:

In Fig. 1, the electrical junction box quick plug comprises inserted link 2, is provided with on inserted link 2 by inserted link front end projection and extend to the shell fragment 1 of inserted link end gradually backward, be provided with ratchet 5 layer by layer with terminal box hole wall 4 contact-making surfaces on the shell fragment 3 among Fig. 2, described shell fragment 3 is connected with inserted link 2 by shell fragment matrix 1.Among Fig. 3, shell fragment matrix 1 is a cylindrical snare, and its internal diameter is corresponding with the inserted link external diameter, and shell fragment is arranged on the shell fragment outer surface of matrix.Described shell fragment matrix 1 can be curled into the cylindrical snare of open-ended by side's bar shaped elastic sheet.

Described shell fragment matrix and inserted link can adopt the connected mode of welding, also can adopt shown in Fig. 1, on the inserted link outer surface by the inserted link end offer radially that a width is corresponding with the shell fragment width, the degree of depth and shell fragment thickness corresponding groove, with the shell fragment setting wherein.

Owing to adopted said structure, replaced the elasticity hook with the ratchet on the shell fragment, eliminated the gap between elasticity hook and the inserted link end, thereby reduced because of the gap precision requirement between elasticity hook and the inserted link end, simplified processing cost, simultaneously, butted line box wall thickness does not require yet, when the utility model electrical junction box quick plug inserts terminal box, ratchet on the shell fragment will fasten the terminal box wall, because of shell fragment be by the inserted link front end backward gradually the projection and extend to the inserted link end, insert dark more will be tight more, thereby form firm connection.

More than be specific embodiments more of the present utility model, those skilled in the art also should belong to protection range of the present utility model not breaking away from the equivalent transformation that spirit of the present utility model makes.
