Description
Technical field
The utility model is related to fuse, and more specifically it is related to a kind of fuse base.
Background technology
Fuse base is the housing for being used to install fuse-link.Application publication number is CN105097379A's in the prior art
Chinese patent document discloses a kind of fuse, and a kind of fuse base structure is disclose in detail in its application documents：Fuse
Base, side is provided with least two groups connector assemblies, and opposite side is provided with least two groups connector assemblies, the wiring group of the both sides
Part position correspondence, fuse base is additionally provided with multiple base contacts, and each connector assembly is respectively connected with and its position pair
On mutually insulated between the base contact answered, connector assembly, the base contact of the corresponding setting of the corresponding connector assembly in both sides
Lower superposition is set；Melt is carried, superposition setting above and below the vestibule of fuse element, vestibule can be placed by being provided with least two groups, and with melting
Disconnected device base contact position correspondence；Carry melt from fuse base transfer to when, at least four fractures can be formed simultaneously；Fusing member
Part, the fuse element quantity is at least two, is arranged in the vestibule for carrying melt, carries melt and is plugged on inside fuse base
Afterwards, fuse element is electrically connected with base contact.
Although existing above-mentioned fuse has preferable performance, the requirement to manufacturing process is very strict, its
It is mainly reflected in：Above-mentioned fuse is by setting base contact corresponding with connector assembly to be contradicted with fuse-link two ends, and base is touched
Head is contacted with fuse-link two ends for point, and fuse base will not only ensure the accuracy of base contact installation site when manufacturing, together
When also to ensure the accuracy of fuse length, error usually requires that control within positive and negative 0.3mm, is compared with Gao Shui in industry
Put down, and a kind of fuse base of specification is only capable of using corresponding to a kind of fuse-link；Emphasis is also resided in, fuse-link in the fuse
And base contact is set for multigroup superposition, as long as having a fuse-link or base contact to produce dimensional discrepancy, all can
Whole fuse is caused the situation of loose contact occur, so as to produce defective products, rework rate is higher；The problem is puzzlement downstream system
Make the problem of manufacturer.
Utility model content
In view of the deficienciess of the prior art, the first purpose of the present utility model is to provide a kind of fuse base, can
The requirement to machining accuracy is substantially reduced, yield rate is improved；And suitable for the fuse-link of the different plurality of specifications of length dimension, carry
High production efficiency and economic benefit.
To achieve the above object, the utility model provides following technical scheme：A kind of fuse base, including housing with
And be slidably connected in the load melt in housing, the housing provided with least two groups contact assemblies being parallel to each other, every group of contact
Component includes two base contacts being oppositely arranged, and the base contact includes the elasticity for being used to be clamped in the side wall of fuse-link two
Intermediate plate and the connecting part electrically connected with elastic clip；The load melt is provided with neck corresponding with contact assembly quantity,
The neck is included for fuse-link from the bayonet socket being radially inserted into and for the clamping part with fuse-link formation interference fit；Carry molten
When body skids off housing, the fuse-link and elastic clip for being fixed on neck are simultaneously switched off；When load melt is slipped into housing, card is fixed on
The fuse-link of groove is contacted simultaneously with elastic clip.
By using above-mentioned technical proposal, the contact knot that traditional fuse-link leans on end face to be contacted with conductive component point has been abandoned
Structure；In this programme, base contact contacts realization electrical connection with the side wall at fuse-link two ends using elastic clip；Due to elastic clip
There is longer axially contact distance between piece and fuse-link, even if there is axial deviation in the size of elastic clip and fuse-link,
Also can be that fuse-link and elastic clip provide stable electrical contact.
In addition, in this programme, fuse-link use instead the mode that is caught in neck from radial direction and is interference fitted with neck so as to
It is fixed on load melt, solves traditional scheme, fuse-link inserts the problem of vestibule easily slides out from melt side is carried.And compare
Traditional approach, this programme is more applicable for the fuse-link of the different plurality of specifications of length dimension；It is embodied in, according to tradition
Vestibule structure is used to insert fuse, and fuse-link insertion vestibule easily slides axially so that fuse-link two ends and elastic clip
Contact surface is difficult to balance, and influences stability in use；And increase assembly difficulty, even if the aperture of vestibule is reduced so that with fusing
Body formation interference structure, but because the two ends end cap inner face that the fuse base is directed to the fuse-link used is angular structures,
So that fuse-link only one may be inserted into vestibule, other end cannot be introduced into due to the conflict effect of end cap inner face and vestibule edge
Vestibule, even if filling in by force, is required for axially promoting fuse-link, fuse-link two ends end cap and vestibule at adjustment fusing body position
Inwall is scraped, and causes assembling difficult, it is easier to damage fuse-link.This programme is also to be proposed according to above mentioned problem, for length
The different fuse-link of size is spent in use, fuse-link need to only be placed to the bayonet socket edge pre-adjustment position of neck, then by fuse-link
It is pressed into neck and is interference fitted with neck, does not damage fuse-link, and assemble very convenient.
