After adopting above-mentioned scheme can effectively reduce the height of welding back electric capacity, its rational in infrastructure, excellent in use effect.

Description

Flat-pin reverse welding capacitor

Technical Field

The utility model relates to a condenser especially indicates a flat foot reverse welding electric capacity.

Background

Traditional condenser stitch is the welding of forward direct formula, and the electric capacity core is above the stitch after welding promptly, and the electric capacity occupation space of this kind of mode installation is big, and the welding contact surface between stitch and the external component is little simultaneously, easy loose welding.

Disclosure of Invention

An object of the utility model is to provide a flat foot reverse welding electric capacity that excellent in use effect, occupation space are little.

In order to achieve the above object, the present invention provides a technical solution: the utility model provides a flat foot reverse welding electric capacity, it is including the electric capacity main part, and electric capacity main part one end is connected with two stitches, and electric capacity main part upper portion shrink forms beam waist groove, and stitch horizontal cross section is rectangle, and two stitch cross section length directions are parallel to each other, and the stitch middle part is bent to electric capacity main part both sides and is formed n shape buffer segment, and the outside level extension in n shape buffer segment lateral wall bottom forms the welding limit, and the electric capacity main part top in one of them stitch outside is equipped with the negative pole sign.

The stitch at the negative pole identification position is a negative pole stitch.

The horizontal plane of the bottom of the welding edge is higher than the horizontal plane of the top of the capacitor main body.

The bending directions of the two pins are opposite, and the central lines of the two extended welding edges are positioned on the same straight line.

The distance between the outer side walls of the n-shaped buffer sections of the two pins is larger than the outer diameter of the capacitor main body.

By adopting the above technical scheme, the utility model, adopt flat stitch, the contact surface is bigger when making the welding, welding limit bottom and outside part contact welding (just to the welding limit of electric capacity core), the welding limit of rectangular shape makes the welding more firm, difficult loose welding, adopt n shape buffer segment can carry out certain distance skew to the electric capacity core after the welding and adjust (pull the electric capacity main part and adjust), it is better to make electric capacity mounted position, adopt the height that can effectively reduce electric capacity after this kind of mode welding, its is rational in infrastructure, excellent in use effect.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, and the preferred embodiments of the present invention are:

example 1

Referring to fig. 1 and fig. 2, the flat-pin reverse-welding capacitor described in this embodiment includes a capacitor main body 1, one end of the capacitor main body 1 is connected with two pins 2, the upper portion of the capacitor main body 1 is contracted to form a beam waist groove, the horizontal cross sections of the pins 2 are rectangular, the length directions of the cross sections of the two pins 2 are parallel to each other, the middle portions of the pins 2 are bent toward two sides of the capacitor main body 1 to form n-shaped buffer sections 3, the bottom portions of the outer side walls of the n-shaped buffer sections 3 extend outward horizontally to form welding edges 5, the bending directions of the two pins 2 are opposite, the central lines of the two extended welding edges 5 are located on the same straight line, the top of the capacitor main body 1 outside one pin 2 is provided with a negative pole identifier 4, the pin 2 at the negative pole identifier 4 is a negative pole pin, the negative pole identifier is used to prevent miswelding of the, can push down n shape buffer segment lateral wall, make welding limit bottom horizontal plane be less than electric capacity main part bottom horizontal plane), the distance between 3 lateral walls of n shape buffer segment of two stitches 2 is greater than electric capacity main part 1 external diameter. Adopt flat stitch, the contact surface is bigger when making the welding (can only flatten welding limit 5 as required, all the other positions adopt circularly), welding limit bottom and external component contact welding (just to the welding limit of electric capacity core), the welding limit of rectangular shape makes the welding more firm, difficult loose welding, the electric capacity of this embodiment is especially suitable for being used for circuit boards such as ceiling lamp \ ceiling lamp to use (ceiling lamp \ ceiling lamp circuit board is for reducing weight, it has the hole that runs through from top to bottom to open on its circuit board, the electric capacity main part of this embodiment can just imbed downtheholely), adopt n shape buffer segment can carry out certain distance skew to the electric capacity core after the welding and adjust (pull electric capacity main part and adjust), make electric capacity mounted position better.

Embodiment 2, referring to fig. 3, the difference between this embodiment and embodiment 1 is that the middle portion of the pin 2 is bent toward two sides of the capacitor body 1 to form an n-shaped buffer section 3, the bottom portion of the outer sidewall of the n-shaped buffer section 3 extends outward horizontally to form a welding edge 5, and straight-edge corners are adopted among the pin 2, the n-shaped buffer section 3, and the welding edge 5.

Embodiment 3, referring to fig. 4, this embodiment is different from embodiment 1 in that, instead of using the buffer section, the welding edge 5 is formed by bending the upper portion of the pin 2 outwards, and the distance between the outer ends of the two welding edges 5 is greater than the outer diameter of the capacitor body 1.

The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
