Description

Coil assembly

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the electronic component field, concretely relates to coil assembly.

[ background of the invention ]

The coil is a device which works by utilizing the principle of electromagnetic induction, when current passes through a wire, a certain electromagnetic field is generated around the wire, the wire is regularly wound to form a regular magnetic field, the hollow coil has a certain blocking effect on alternating current and has a corresponding relation with alternating current frequency, and the total potential and the current change in the hollow coil also have a certain counter effect; the air core coil also has a capacitive reactance in the loop, and electromagnetic energy can tune the frequency.

Hollow coil is owing to simple structure, and the cost is cheap, is playing very big effect in the circuit, but because its sleek structure, can't stabilize the location in the circuit, leads to the automation installation of can't collocating with the connection of circuit, can only assemble through manual mode, causes production efficiency low, and single worker still can lead to the product defective rate to improve moreover, has increased manufacturing cost.

[ Utility model ] content

In order to solve the existing problem that exists among the background art, the utility model provides a coil assembly.

The utility model adopts the following technical proposal:

a coil assembly comprises a coil box and a coil body arranged in the coil box, wherein the coil body is a hollow coil formed by winding a copper wire, pins extend out of two ends of the coil body in a straight line, the coil body is arranged in the coil box and packaged through a plastic film, and the pins are convexly arranged outside the coil box.

Further, the coil box is an integrated casing which is made of iron material and the surface of which is coated with antirust paint.

Furthermore, the two longer side plates of the coil box are provided with the same notches close to the two sides of the opening, and the pin adapter is clamped in the notches and extends out of the notches.

Further, the notch is an arc-shaped opening.

Furthermore, the pins are positioned on the same horizontal plane and extend in opposite directions in parallel with each other.

The utility model has the advantages as follows:

the utility model discloses a design one can match the firm coil box of placing the coil body to can be accurate and quick location coil body through the notch on the coil box, carry out plastic film encapsulation shaping again, insert the circuit board at last, whole accessible automated mode assembles the access welding with the circuit, and production efficiency is high, has reduced the defective products simultaneously and has taken place, thereby reduction in production cost.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

The utility model provides a coil assembly, includes coil box 1 and adorns in coil body 2 inside the coil box 1, coil body 2 forms hollow coil for the winding of copper line, and coil body 2 twines through the mode of close winding, simultaneously the outside straight line in coil body 2 both ends extends pin 3, pin 3 is in on the same horizontal plane and extends toward opposite direction mutually in parallel, and pin 3 is used for connecting outside circuit board, connects through the welded mode.

The coil box 1 is an integrated casing, in the utility model, the coil box 1 is made of iron material, in order to prevent rusting, the outer surface is coated with antirust paint and dried at last, the coil box 1 is a cuboid, the top is an opening, a punching machine is used for one-step punch forming, in order to facilitate the rapid and accurate positioning and assembling of the pins 3, the same notches 4 are arranged at the two sides of the longer two side plates of the coil box 1 close to the opening, the notches 4 are arc-shaped openings, the height, the length and the width of the coil box 1 are all matched with the size of the coil body 2, so that after the coil body 2 is placed into the coil box 1, the pins 3 are clamped in the notches 4 and extend out of the coil box 1, finally, the plastic film is packaged into a fixed body, and finally the coil assembly and the circuit board are welded, compared with the prior single coil body, the utility model discloses a positioning and automatic assembling, the efficiency is greatly improved, and the reject ratio caused by manual work is avoided.

The utility model has the advantages that:

the utility model discloses a design one can match the firm coil box of placing the coil body to can be accurate and quick location coil body through the notch on the coil box, carry out plastic film encapsulation shaping again, insert the circuit board at last, whole accessible automated mode assembles the access welding with the circuit, and production efficiency is high, has reduced the defective products simultaneously and has taken place, thereby reduction in production cost.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
