Abstract

The utility model discloses a pin shift preventing transformer which comprises a skeleton, pins and a pin base, wherein fixing plates are respectively arranged on the two sides of a transverse plate on the skeleton, and a primary coil is arranged on the transverse plate; the pin base is arranged at the bottom of the transverse plate; and one end of the pins are inserted into the pin base. According to the utility model, the transverse strength of the skeleton is improved, and the problems that a conventional transformer is susceptible to coil tension to deform during roasting, and consequently, the pins shift and a PCB (printed circuit board) is difficult to insert into a client are effectively solved.

Description

A kind of transformer of anti-pin displacement

Technical field

The utility model relates to a kind of transformer, particularly a kind of anti-pin displacement transformer that uses on high-power energy-saving lamp.

Background technology

At present, light fixture generally all can use the skeleton of PET material with voltage device, but the transformer that uses the PET material to make toasts in process of production and be subject to the coil pulling force and produce distortion, causes the pin displacement, makes client insert the pcb board hard problem.

The utility model content

Utility model purpose: for existing transformer to produce distortion because baking is subject to the coil pulling force in process of production in above-mentioned prior art, cause the pin displacement, make client insert the pcb board hard problem, the utility model provides a kind of transformer of anti-pin displacement.

Technical scheme: for realizing above-mentioned utility model purpose, the utility model provides a kind of transformer of anti-pin displacement, comprise skeleton, pin and pin base, wherein, the transverse slat both sides that primary coil is set on described skeleton are respectively equipped with fixed head, the transverse slat bottom is provided with pin base, and an end of described pin is inserted on pin base.

Be provided with salient point outside pin base, enamelled wire is by after hanging over salient point like this, be wrapped with pin and cushion enamelled wire to the pulling force of pin, utilize the buffering of transverse slat and salient point, the displacement that pin occurs the tension force that when reducing pin and toasting due to transformer, coil produces.

Wherein, the fixed head of transverse slat both sides is preferably trapezoidal, is more suitable for like this structure of skeleton, makes skeleton more stable, and is not yielding.

Beneficial effect: compared with prior art, the utility model not only increases the horizontal intensity of skeleton, and efficiently solve transformer and produce distortion because baking is subject to the coil pulling force in process of production, cause the pin displacement, make client insert the pcb board hard problem.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.

As shown in Figure 1, a kind of transformer of anti-pin displacement comprises skeleton 1, pin 2 and pin base 3, wherein, transverse slat 4 both sides that primary coil is set on described skeleton 1 are respectively equipped with fixed head 5, and transverse slat 4 bottoms are provided with pin base 3, and an end of described pin 2 is inserted on pin base 3.

Wherein, be provided with salient point 6 in the outside of pin base 3, enamelled wire by after hanging over salient point 6, is wrapped with pin 2 and cushions enamelled wire to the pulling force of pin 2 like this, utilize the buffering of transverse slat 4 and salient point 6, the displacement that pin 2 occurs the tension force that when reducing pin 2 and toasting due to transformer, coil produces.

In order to be more suitable for the structure of skeleton, make skeleton more stable like this, not yielding, the fixed head 5 of transverse slat 4 both sides is preferably trapezoidal.
