Abstract
The invention relates to a lead pin type electronic transformer which comprises a transformer wire support and a lead pin. The lead pin is inserted into the transformer wire support, and inverted sharp thorns are arranged on the side portion of the inserting end of the lead pin. According to the lead pin type electronic transformer, the sharp thorns are arranged at the inserting end of the lead pin, so that the lead pin does not fall off the transformer wire support easily, the quality of the electronic transformer is guaranteed, and waste of the production cost is reduced.
Description
Technical field
The present invention relates to electronic product field transformer, especially one is drawn pin type electronic transformer.
Background technology
The existing pin transformer that draws is provided with and draws pin, be transformer pin, transformer contact pin or transformer PIN pin, be mainly used on charger transformer, audio frequency transformer, plug wire road board transformer, make a kind of electronics that transformer is connected with printed circuit board (PCB) connect product.
It is direct insertion that the electronic transformer product using at present draws pin implantation, will draw exactly pin and directly be inserted on transformer coil holder, and be drawn pin and be connected with printed circuit board (PCB) by this.But, adopt above-mentioned means to implant while drawing pin, draw pin and be easy to be subject to pulling capacity and drop out transformer coil holder, use transformer cannot insert printed circuit board (PCB), affect the normal use of electronic transformer.
In order to overcome the above problems, the present invention has done useful improvement.
Summary of the invention
(1) technical problem that will solve
The pin that draws that the object of the invention is to overcome existing electronic transformer holds caducous technical problem.
(2) technical scheme
The present invention is achieved by the following technical solutions: one is drawn pin type electronic transformer, comprise transformer coil holder and draw pin, described in draw pin and be inserted in described transformer coil holder; The described insertion end sidepiece that draws pin is provided with the spine of handstand.
Wherein, described in to draw pin be cylindrical or square, and this insertion end of drawing pin is provided with multiple spines; Described multiple spines draw being circumferentially uniformly distributed of pin described in edge.
Further, described in, draw and in the insertion end of pin, be provided with 2～3 circle spines.
(3) beneficial effect
Compare with product with prior art, the present invention has the following advantages:
The present invention can, by the insertion end sidepiece that draws pin, spine being set, be difficult for coming off from transformer coil holder thereby make to draw pin, ensures the quality of electronic transformer, reduces the waste of production cost.
Brief description of the drawings
Fig. 1 is the structure chart that draws pin type electronic transformer of the present invention;
Fig. 2 is the needle construction figure that draws of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
As shown in Figure 1, the invention provides a kind of high-intensity pin type electronic transformer that draws, it comprises transformer coil holder 2 and draws pin 1, described in draw pin 1 and be inserted in described transformer coil holder 2; To draw in order overcoming the technical problem that pin easily comes off from transformer coil holder, in insertion end of drawing pin 1 of the present invention, to be provided with the spine 11 of handstand at this sidepiece that draws pin 1.In the present embodiment, need to implant the insertion end of drawing pin of transformer coil holder with texture machine and get the spine of handstand, in the time drawing pin insertion transformer coil holder, be convenient to insertion pin guiding along the direction of spine like this, extracting can be against the direction of spine while drawing pin, needs larger power just can extract.Be difficult for coming off from transformer coil holder thereby make to draw pin, ensure the quality of electronic transformer, reduce the waste of production cost.
Described insertion end of drawing pin 1 is provided with multiple spines 11, and this draws pin 1 and can adopt cylindrical or square.The two opposite side surfaces that described multiple spine 11 can the side's of being arranged on bar shaped draws pin, also can be evenly distributed on described cylindrical or square week of drawing pin 1 upwards.Preferably, described spine 11 draws in the insertion end of pin 1 described in being arranged on round.In described insertion end of drawing pin 1, be provided with 2～3 circle spines 11.Thereby ensure to draw the stability that pin is connected with transformer coil holder.
Above execution mode is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
Claims (3)
1. draw a pin type electronic transformer, it is characterized in that, comprise transformer coil holder and draw pin, described in draw pin and be inserted in described transformer coil holder; The described insertion end sidepiece that draws pin is provided with the spine of handstand.
2. the pin type electronic transformer that draws according to claim 1, is characterized in that, described in to draw pin be cylindrical or square, and this insertion end of drawing pin is provided with multiple spines; Described multiple spines draw being circumferentially uniformly distributed of pin described in edge.
