Abstract

The utility model discloses a fastening device for a lightning protection device. The lightning protection device comprises an insert module (1) and a bottom seat (2) with an insert groove (2- 1), wherein the insert groove (2- 1) is adaptive with the insert module (1) and a pressure slice (1-1) is respectively arranged on two side surfaces of the insert module (1) and a fastener (1-2) is respectively arranged on the pressure slice, a spring is mounted between two pressure slices (1-1) and a bayonet (2-2) adaptive with the fastener (1-2) is arranged in the insert groove (2-1). Even in the bump, long-period movable environment, the insert module (1-1) is not away from the bottom seat (2), therefore the lighting protection device can work at a normal state and the service life of the lighting protection device is prolonged.

Description

A kind of bayonet unit that is used for lightning protection device

Technical field

The utility model relates to a kind of bayonet unit, is specifically related to a kind of bayonet unit that is used for lightning protection device.

Background technology

Lightning protection device comprises insert module and base, and base is provided with the insertion groove that is " recessed " type with insert module is suitable, inserts groove and is used to supply insert module to insert.But be provided with the projection of two conducting electric currents on the existing insert module at least, in inserting groove, be provided with and the suitable socket that is used to supply the projection insertion of projection; After combining like this; Though lightning protection device can normally use, insert module is not fastening with being connected of base, if be installed on the moving vehicle; The long-term insert module and the base that can make lightning protection device that jolt breaks away from; Do not have the due effect of lightning protection device, the lightning protection device effect is not identical with installing, thereby has influenced the useful life of lightning protection device.

The utility model content

To the deficiency that prior art exists, the utility model purpose provides a kind of bayonet unit that insert module and base is connected firmly and is easy to plug insert module, thereby has prolonged the useful life of lightning protection device.

To achieve these goals, the utility model is to realize through following technical scheme:

The lightning protection device of the utility model comprises insert module and has the base that inserts groove; It is suitable to insert groove and insert module, is equipped with compressing tablet on the two sides of insert module, and compressing tablet is provided with buckle; Between two compressing tablets spring is installed, inserts in the groove and be provided with the bayonet socket suitable with buckle.

Also be provided with the track groove on the two sides of above-mentioned insert module, insert and be provided with the track convexity suitable in the groove with the track groove.

But be provided with the projection of two conducting electric currents on the above-mentioned insert module at least, insert in the groove and be provided with the socket suitable with projection.

Also be provided with anti-slide plate on the above-mentioned compressing tablet.

Time saving and energy saving, flexible aspect that the utility model uses; Even make lightning protection device in the environment that jolts, moves for a long time, insert module can not break away from from base yet, thereby makes the lightning protection device can operate as normal, has prolonged the useful life of lightning protection device; The utility model is applicable to the needs that the various device lightning protection device is installed, and is particularly useful for the environment that motor vehicles move for a long time, jolt.

Description of drawings

Fig. 1 is the overall structure sketch map of the utility model;

Fig. 2 is the understructure sketch map of the utility model;

Fig. 3 is the insert module structural representation of the utility model.

Each label among the figure: insert module 1, base 2, compressing tablet 1-1, buckle 1-2, track groove 1-3, projection 1-4, anti-slide plate 1-5 inserts groove 2-1, bayonet socket 2-2, the protruding 2-3 of track, socket 2-4.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.

Referring to Fig. 1, the lightning protection device of the utility model comprises insert module 1 and has the base 2 that inserts groove 2-1 that insert groove 2-1 and be " recessed " type, it is suitable to insert groove 2-1 and insert module 1.

Referring to Fig. 2 and Fig. 3, but be provided with the projection 1-4 of two conducting electric currents on insert module 1 bottom surface at least, the front of inserting groove 2-1 is provided with the socket 2-4 suitable with projection 1-4.

Be equipped with the compressing tablet 1-1 and the track groove 1-3 that can push on the upper and lower two sides of insert module 1; Track groove 1-3 is provided with two, and all is positioned at the edge of side; Compressing tablet 1-1 is provided with buckle 1-2 and anti-slide plate 1-5, and spring (not drawing among the figure) is installed between the two compressing tablet 1-1.

The upper and lower side of inserting groove 2-1 is provided with the bayonet socket 2-2 suitable with buckle 1-2, also is provided with the track protruding 2-3 suitable with track groove 1-3 in the upper and lower side of inserting groove 2-1.

The utility model inserts socket 2-4, buckle 1-2 insertion bayonet socket 2-2 through projection 1-4, and the protruding 2-3 of track inserts track groove 1-3, just can insert module 1 tightly be stuck on the base 2, prevents that insert module 1 breaks away from base 2.

Insert module 1 is installed: the track groove 1-3 of insert module 1 is aimed at the protruding 2-3 of track of base 2, and the projection 1-4 of insert module 1 aims at the socket 2-4 of base 2, at first pushes the compressing tablet 1-1 of both sides; This moment, spring shrank, and made buckle 1-2 get into bayonet socket 2-2, stopped to push the compressing tablet 1-1 of both sides then; This moment, spring stretched out; Buckle 1-2 and bayonet socket 2-2 are fastened, insert module 1 and base 2 are fastenedly connected, can not cause the lightning protection device isolation of components because of non-artificial factor.

Extract insert module 1: push compressing tablet 1-1, this moment, spring shrank, and buckle 1-2 is withdrawed from from bayonet socket 2-2, just can be with insert module 1 extracting easily and fast.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
