Abstract
The utility model provides a kind of wire resistor, including insulating body, it is arranged on the weld cap at the insulating body two ends, the resistance wire being wrapped on the insulating body, the resistance wire two ends are respectively welded on weld cap described in two ends, the weld cap surface setting is fluted, and the resistance wire is welded in the groove.By resistance wire is welded in groove, it is to avoid in production process, solder joint meets the rosin joint that other objects cause, the significant increase yields of finished product.
Description
Technical field
The utility model is related to electronic devices and components field, more particularly to a kind of wire resistor.
Background technology
The use of wire wound resistor is more and more extensive, and demand is increasing.Chinese patent CN201838410U discloses one
Kind of wire wound resistor structure, including matrix, the resistance wire being wrapped on matrix and is arranged on the weld cap at matrix two ends, resistance wire bond
It is connected on the weld cap at two ends, Chinese patent CN205211514U, CN105590708A also disclose similar wire resistor respectively
Device structure.However, as resistance wire is welded on weld cap, and weld cap surface is smooth, after welding, solder joint will be projected in weldering
Cap surface, in process of production, especially for circular weld cap, solder joint is easy to meet other objects, causes often appearance
The situation of rosin joint, causes fraction defective to remain high always, how the yields of improving product, has become that industry is urgently to be resolved hurrily to ask
Topic.
Content of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of coiling electricity for solving the above problems
Resistance structure.
The technical scheme adopted for achieving the above object by the utility model is：
A kind of wire resistor, including an insulating body, is arranged on the insulating body two ends
Weld cap, the resistance wire being wrapped on the insulating body, the resistance wire two ends are respectively welded at described in two ends and weld
On cap, the surface setting of the weld cap is fluted, and the resistance wire is welded in the groove.
Preferably, the longitudinal section of the weld cap is inverted T shape, and the groove is the depression position of T-shaped bottom.
Preferably, the insulating body, the weld cap and the resistance wire are provided with one layer of thermal dispersant coatings.
Further, the weld cap is for ease of the square weld cap of paster.
Preferably, the insulating body and the weld cap are coated with encapsulating shell, and the encapsulating shell extends from weld cap
The termination electrode of sheet, the termination electrode flanging shaping.
Of the present utility model have the technical effect that, by arranging groove position in weld cap upper surface, resistance wire is welded on groove position
Place, it is to avoid the rosin joint that the mutual collision of solder joint and other objects is caused, greatly improves the yields of finished product.
Below in conjunction with the accompanying drawings the utility model is specifically described.
Description of the drawings
Fig. 1 is the structural representation of the utility model first embodiment.
Fig. 2 is the structural representation of the utility model second embodiment.
Wherein corresponding relation is, insulating body 1, weld cap 2, resistance wire 3, groove 4, solder joint 5, encapsulating shell 6, termination electrode 7.
Specific embodiment
Embodiment 1：
Referring to accompanying drawing 1, a kind of wire resistor, including insulating body 1, weld cap 2, resistance wire 3, insulating body 1 can be according to realities
Border is needed using materials such as ceramic matrix, cement matrixes, and 1 two ends installation settings of insulating body has weld cap 2, for ease of paster, is welded
Cap 2 may be designed to square structure.Resistance wire 3 is wrapped on insulating body 1, and two ends are respectively welded at the weldering at 1 two ends of insulating body
On cap 2.
2 surface of weld cap arranges fluted 4, for ease of arranging groove 4, it is preferable that weld cap 2 is arranged to longitudinal section for inverted T shape
Shape, then can be used as groove 4 at T-shaped undercut.Resistance wire 3 is welded in groove 4, and whole solder joint 5 is hidden in recessed
In groove 4, even if being subject in process of production to collide with other objects, it is also difficult to encounter solder joint, so as to reduce the probability of rosin joint, carry
Rise finished product yields.Certainly groove 4 also has other designs, for hiding solder joint 5, all in protection domain of the present utility model
Within.
For strengthening radiating effect, insulating body 1, resistance wire 3 and weld cap 2 are also provided with one layer of thermal dispersant coatings.
Embodiment 2：
Referring to accompanying drawing 2, the utility model embodiment 2 with the difference of embodiment 1 is, in insulating body 1, the outer increase of weld cap 2
One layer of encapsulating shell 6, extends the termination electrode 7 of sheet from weld cap 2 and is exposed to the outer both sides of encapsulating shell 6, and 7 flanging of termination electrode becomes
Type, in order to paster.
Certainly, this utility model can also have other conversion, it is not limited to above-mentioned embodiment, those skilled in the art
The knowledge for being possessed, can also various changes can be made without departing from the concept of the premise utility, such change all should
Fall in protection domain of the present utility model.
