Abstract

The utility model discloses a DF framework of a bridge rectifier, which is formed by installing lead pins in a plane framework. The utility model is characterized in that the plane framework is a square framework, the end A and the end B of the square framework have the same structure, two groups of lead pins are integrally formed in the framework, the upper ends of the two groups of lead pins are arranged in opposite directions, the lower ends of the lead pins are respectively connected with the end A and the end B of the square framework into a whole body, and the lead pins are also fixed to the square framework through reinforcing ribs. The utility model has the advantages that the integral framework is adopted, the installation is convenient, the problem of staggered position of combination parts during the installation is effectively controlled, the whole framework adopts the plane design, and the glue brushing rate is effectively improved.

Description

A kind of bridge rectifier D F framework

Technical field

The utility model relates to a kind of bridge rectifier D F framework, is specifically related to a kind ofly by the pin that distributes in the framework, can carry out the bridge rectifier D F framework that the packing of DF form forms the bridge rectifier of DF packing forms to the upper end of pin then.

Background technology

Traditional bridge rectifier D F framework is split type framework, and the pin configuration in its two framework is identical, is equipped with boss on pin.When making product, the upper end clamping chip of two groups of pins is involutory then, encapsulate again, form finished product.The shortcoming of this structure is: described framework is split type, and when encapsulating, the joint portion branch of pin end misplaces because of external force, influences the quality of finished product.In addition because pin is provided with boss, only cannot brush coating when causing printing glue with a glue, reduce operating efficiency.

The utility model content

The utility model relates to a kind of bridge rectifier D F framework, is specifically related to a kind of convenience and installs, is beneficial to the bridge rectifier D F framework that guarantees product quality and can effectively improve brush coating efficient.

In order to solve above technical problem, a kind of bridge rectifier D F framework described in the utility model constitutes by establishing pin in the plane framework, it is characterized in that: described plane framework is the identical hollow framework of both ends A, B structure, global formation has two groups of pins in described framework, arrange in opposite directions these two groups of pin upper ends, the bottom connects as one with hollow framework both ends A, B respectively, and described pin is also by reinforcement and hollow frame fixation.

Further, one group of pin of A place, described plane framework end global formation, described this group pin is two, and shape is identical, and its shape all is the shape that " F " removes middle little horizontal line, and two pins distribute relatively.

Further, one group of pin of B place, described plane framework end global formation, described this group pin also is two, the inequilateral U type that is shaped as of one of them pin, another is shaped as: the upper end of pin is an inequilateral U type; Being distributed as of described two groups of pin upper ends: the minor face of two pins inequilateral U type all is embedded in the cavity of U type.

Advantage of the present utility model is: adopt integral frame, and convenient the installation, binding site problem of misalignment when effectively control is installed, and whole framework adopts planar design entirely, effectively improves the brush coating rate.

Description of drawings

Figure is the utility model structural representation.

Embodiment

As shown in the figure, the utility model employing molds bridge rectifier D F framework by the integral forming method of the needed parts of punching removal redundance formation the utility model on a copper sheet.

Therefore this framework integral body in one plane be called plane framework 1, described plane framework is the identical hollow framework of both ends A, B structure, global formation has two groups of

pins

2,3 in described plane framework 1, arrange in opposite directions these two groups of pins, 2,3 upper ends, the bottom connects as one with hollow framework both ends A, B respectively, and described

2,3 is also fixedlyed connected with plane framework 1 by

reinforcement

4,5 respectively.

One group of pin 2 of A place, above-mentioned plane framework end global formation, its pin is two, is called 2a, 2b, and shape is identical, and its shape all is the shape that " F " removes middle little horizontal line, and two pins distribute relatively; One group of pin of B place, plane framework end global formation is two also, is called pin 3a, 3b, the inequilateral U type that is shaped as of described pin 3a, and another pin 3b is shaped as: the upper end of pin 3b is an inequilateral U type; Being distributed as of described two groups of pin 3a, 3b upper end: the minor face of two pins inequilateral U type all is embedded in the cavity of U type, and is separated from each other.

Above-mentioned

2,3 upper ends are equipped with the chips welding district, and place's soldering has chip 7 in the chips welding district.

When product is assembled, being connected to of two groups of pins 2,3: be connected by wire jumper 8 solderings with pin 3a by the chip on the pin 2a 7; Certainly the chip 7 on the pin 3b connects and composes by wire jumper 8 solderings with pin 2b, and the like.Like this, the encapsulation by the DF form of the pin that connects is encapsulated it, and then excision reinforcement 6 and other unnecessary leftover pieces, finished product formed.
