Description
Technical field:
The utility model relates to electric elements technical field, more specifically to a kind of cylindricality power resistor.
Background technique:
It is usually one hollow iron set of the artificial dispensing in middle part of a ceramics insulator in existing cylindricality resistor,
And single ceramic insulator length is too long, cost of manufacture is high, when hollow iron set is installed at middle part, binder is used to fix, and holds
Easy degumming, firmly installs that degree is low, and effect is poor.
Utility model content:
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of cylindricality power resistor, it uses two
A ceramics insulator replaces a long ceramics insulator, and cost substantially reduces, meanwhile, the mutually pressing end of two ceramics insulators with
Hollow iron body holding is fixed, fixation, it is not easy to be detached from hollow iron set, long service life.
The scheme that the utility model solves the technical problem is:
A kind of cylindricality power resistor, including two ceramics insulators, one end of described two ceramics insulators are mutually pressed
By and holding in the inner sidewall of hollow iron body, the equal holding in mutually separate one end of two ceramics insulators is in end conductive shield
In, electric connection line, outside wall surface of the electric connection line in corresponding ceramics insulator are equipped between end conductive shield and hollow iron body
On, one end of electric connection line is connected with end conductive shield, and the other end of electric connection line is connected with hollow iron body.
The end conductive shield is irony cover.
Conducting rod is fixed on the lateral wall of the end conductive shield.
The electric connection line is resistive conductor or fusible link.
The electric connection line coils the lateral wall for being close to ceramics insulator in the shape of a spiral.
The protrusion effect of the utility model is:
Compared with prior art, it replaces a long ceramics insulator using two ceramics insulators, and cost substantially reduces,
Meanwhile the mutually pressing end of two ceramics insulators is fixed with hollow iron body holding, fixation, it is not easy to make hollow iron set
It is detached from, long service life.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model.
Specific embodiment:
The utility model is elaborated with specific preferred embodiment with reference to the accompanying drawing, so that the utility model
The advantages of and feature can be easier to be readily appreciated by one skilled in the art, these embodiments are only the purpose illustrated, and are existed incessantly
The scope of the utility model is defined.
Embodiment is shown in as shown in Figure 1 to Figure 2, a kind of cylindricality power resistor, including two ceramics insulators 1, described two
One end of a ceramics insulator 1 is mutually pressed against and holding is in the inner sidewall of hollow iron body 2, the phase of two ceramics insulators 1
The equal holding in separate one end is equipped with electric connection line 4, electricity in end conductive shield 3 between end conductive shield 3 and hollow iron body 2
In the outside wall surface of corresponding ceramics insulator 1, one end of electric connection line 4 is connected connecting line 4 with end conductive shield 3, is electrically connected
The other end of wiring 4 is connected with hollow iron body 2.
Further, the end conductive shield 3 is irony cover.
Further, conducting rod 5 is fixed on the lateral wall of the end conductive shield 3.
Further, the electric connection line 4 is resistive conductor or fusible link.
Further, the electric connection line 4 coils the lateral wall for being close to ceramics insulator 1 in the shape of a spiral.
In the present embodiment, ceramics insulator 1 is non-metallic body, has very high mechanical strength, high temperature resistant, good heat
The coefficient of expansion.
The present embodiment, when making, it is only necessary to by the end holding of two ceramics insulators 1 being mutually pressed against to hollow iron set
In 2, the length of two ceramics insulators 1 can be the same or different, and can be selected according to using, similarly, two electricity
Connecting line 4 can according to need to be wound in different ways, it can winding multi-turn number electric connection line 4 as needed, it can also be with
Wind the electric connection line 4 of fewer circle number, moreover it is possible to meet different resistor powers according to the canoe of positive and negative different directions
Needs, then, then the present embodiment is encapsulated into heat-shrinkable T bush, easy to make, effect is good.
Embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, related technology neck
The those of ordinary skill in domain, in the case where not departing from the spirit and scope of the utility model, can also make a variety of changes and
Modification, therefore all equivalent technical solutions also belong to the scope of the utility model, the scope of patent protection of the utility model is answered
It is defined by the claims.
