Abstract
The utility model discloses a fuse tuning fork PIN structure of improvement type, including fuse and tuning fork PIN, tuning fork PIN has two pins, its characterized in that, every the pin is equipped with two at least convex contact points, the fuse is cliied to two pins of tuning fork PIN, makes all the convex contact points on every pin all be connected with the fuse contact. The utility model discloses rate of heat removal is fast, makes the temperature rise of whole electrical apparatus box be in and stabilizes controllable scope, ensures normal operating condition.
Description
Technical field
The utility model relates to automobile electrical equipment box field, refers to a kind of fuse tuning fork PIN structural of modified form especially.
Background technology
The tuning fork PIN of current automobile electrical equipment box on the market, adopt single circular arc wise manner to clamp fuse, in use, the temperature rise of whole electrical appliance kit product is higher.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of temperature rise that can reduce electrical appliance kit, makes product be in stable temperature range, to ensure the fuse tuning fork PIN structural of normal operating conditions.
The technical scheme adopted is:
A fuse tuning fork PIN structural for modified form, comprises fuse and tuning fork PIN, and described tuning fork PIN has two pins, and each described pin is provided with at least two circular arc contact points; Two pins of described tuning fork PIN clamp described fuse, all circular arc contact points on each described pin are all contacted with described fuse and connects.
Preferably, each described pin is provided with two circular arc contact points.
The beneficial effects of the utility model are:
Compared with prior art, adopt many circular arc wise manner, namely each pin at least two circular arc contact points clamp fuse, contact point increases, and contacts that to produce impedance less with fuse, and rate of heat dispation is fast, make whole electrical appliance kit temperature rise be in stable controlled range, ensure normal operating state.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of fuse tuning fork PIN structural of prior art;
Fig. 2 is the structural representation of tuning fork PIN in prior art;
Fig. 3 is the schematic diagram of the fuse tuning fork PIN structural of modified form of the present utility model.
Embodiment
In order to be illustrated more clearly in prior art and the utility model, be further described below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of fuse tuning fork PIN structural of prior art, it comprises fuse 1 and tuning fork PIN2, and tuning fork PIN here refers to the pin with tuning fork structure.Tuning fork (tuningfork) common implication is steel in approximate " Y " shape or aluminium alloy acoustical generator, and various tuning fork can send the pure tone of different frequency when vibration because its quality and yoke length, thickness are different.PIN is the English meaning of pin.As shown in Figure 2, the implication of the parts therefore represented by " tuning fork PIN " should be clearly to the structure of the tuning fork PIN inside the automobile electrical equipment box of the art.This specification said fuse tuning fork PIN structural refers to the device of fuse, tuning fork PIN and tectonic relationship between the two.Therefore, the implication of the device represented by " fuse tuning fork PIN structural " also should be clearly, or those skilled in the art should be clearly with reference to the explanation of this specification.
The tuning fork PIN2 of automobile electrical equipment box has two pins, and two pins of tuning fork PIN2 clamp insurance 1, and pin adopts single circular arc wise manner to clamp fuse.
This is the structure that prior art has, and inventor in use finds, tuning fork PIN contacts with fuse and produces impedance comparatively greatly, makes the temperature rise of whole electrical appliance kit product higher.
Fork PIN how is made to contact with fuse to produce impedance less, make the temperature rise of whole electrical appliance kit product lower? inventor enters deep understanding and analysis to prior art.Because those skilled in the art generally can not relate to this technical problem in the prior art, because it has become a kind of general structure, be it has been generally acknowledged that the rising of its temperature also belongs in normal range (NR), therefore seldom can expect doing improvement.
Therefore, after first inventor confirms the existence of this technical problem, and then analyse in depth the reason place of problem, find that each pin adopts single circular arc wise manner to be in fact adopt single contact point, from but contact point has been electrically connected tuning fork PIN and fuse, when current is excessive, in fact that contact point connects alive circulation, and the area of each contact point is certain (that is to say in the known value range of a fixed value or this area), thus make the impedance of whole tuning fork PIN and fuse larger, thus make the temperature rise of whole electrical appliance kit larger.
After finding this reason, in conjunction with prior art structure and facilitate follow-up improvement or repacking, inventor defines following inventive concept: increase contact point area, reduces to contact the impedance produced with fuse, and defines the utility model:
A fuse tuning fork PIN structural for modified form, comprises fuse and tuning fork PIN, and described tuning fork PIN has two pins, and each described pin is provided with at least two circular arc contact points; Two pins of described tuning fork PIN clamp fuse, all circular arc contact points on each pin are all contacted with fuse and connects.
Namely by increasing contact point (namely at least two), thus increase contact point area, thus the impedance that the contact of tuning fork PIN and fuse is produced is less, thus whole electrical appliance kit temperature rise is in stable controlled range.
And, increase contact point, and the contact point increased also is circular arc contact point, thus follow-up improvement or repacking is become be more prone to, more easily produce in batches.
And increase circular arc contact point, circular arc contact point disperses each other, thus also make rate of heat dispation speed, thus make whole electrical appliance kit temperature rise be in stable controlled range further.
Wherein, " at least two " can be such as 2,3 or 4 etc.
As follows for an embodiment:
Shown in Figure 3, a kind of fuse tuning fork PIN structural of modified form, comprises fuse 1 and tuning fork PIN2, and described tuning fork PIN has two pins, and each described pin is provided with two circular arc contact points 3; Two pins of described tuning fork PIN2 clamp fuse 1, all circular arc contact points 3 on each pin are all contacted with fuse 1 and connects.
The above embodiments are also not used to limit protection range of the present utility model, and all the present utility model that do not depart from are conceived the Equivalent embodiments done or changed and all should be included within protection range of the present utility model.
