Description

A kind of novel transformer based holder structure

The utility model relates to electric type, particularly a kind of novel transformer based holder structure.

At present electronic component is all towards gently, thin, short, little form design, so volume of miniature transformer, thickness has to classify as the emphasis of consideration, as shown in Figure 9, this transformer system is by an iron-dust core (10), one pedestal (20) and a conduction element (30) constitute, can know that from accompanying drawing 9 circumference of finding out iron-dust core (10) and pedestal (20) is not for isometrical, therefore can be on making because pedestal (20) both sides of the edge are located also one group of conduction element of clamping connection (30) again and do not influence iron-dust core (10) again affixed with pedestal (20), the area of pedestal (20) just must be greater than iron-dust core (10), cause the transformer overall volume excessive, and conduction element (30) with the mode clamping connection of clamping connection in pedestal (20), easily make and produce phenomenon loosening and that thickness increases between conduction element (30) and pedestal (20), and conduction element (30) with clamping connection mode clamping connection on pedestal (20), and this pedestal (20) is when being fixed in circuit board surface, because conduction element body foot has certain thickness, can make and produce a gap between base portion and the circuit board, transformer integral body can't be engaged with circuit board plane, other has conduction element directly is embedded in base interior in molded mode, it is for penetrating method for making, before must insert conduction element in die cavity inside, making wage height, and speed of production is slow, on the aforementioned in addition conduction element a single stiff end is arranged in addition, therefore the coil tail end place that is wound on the iron-dust core remains when not growing, can make the coil tail end place can't be affixed, therefore the line end of transformer windings may need to reduce a circle coiling just has enough line ends can be fixed, so fixed position has more limited chance.

The purpose of this utility model is exactly the shortcoming at above-mentioned traditional fabrication transformer, redesigns a kind of novel transformer base construction.

The technical solution of the utility model:

According to the purpose of this utility model, the technical solution of the utility model is to utilize a pedestal that equates body with the iron-dust core floor space, upper surface is for iron-dust core bottom set, the volume-diminished of transformer integral body is not taken up space, use in order to the miniature electric equipment, this base bottom is rabbeted conduction element in the interlocking mode, in order to automated production, and this conduction element has most stiff ends, utilize its stiff end to be divided into different peripheral positions for most, and be not subjected to the restriction of fixed position for twining the compressed-iron-core coil tail end, can select one of the just the most contiguous stiff end affixed, be convenient to assemble and be beneficial to automated production fast, and its automated production mode process is as follows:

1, will penetrate the pedestal finished of system, be delivered in conjunction with work station via the lining-up machine auto arrangement.

2, in last course of conveying, can be about to adhesive earlier via the engaging groove bottom surface of a gluing machine point glue in pedestal.

3, one give earlier the conduction element punching out that is shaped with the strip punching out after, rolling is a web-like, hang on feeding mechanism, by feeding mechanism by with each conduction element with step-by-step system, send in conjunction with work station one by one.

4, via in conjunction with the impact extrusion tongue in the set impact extrusion machine mechanism of work station, align conduction element and the engaging groove of pedestal into of throwing, make it promptly to finish joint after the combination to the position.

The utility model is simple in structure, can carry out automated production, boosts productivity greatly, reduces cost.
