Abstract

The utility model discloses a take voice coil loudspeaker voice coil motor coil supporting structure of vertical wrapping post, including stake body, shell fragment, coil. The middle part of stake body a centre bore has, on the up end of stake body, the both sides of centre bore correspond respectively and set up a perpendicular ascending vertical wrapping post, the solderless wrapped connection is on two vertical wrapping posts respectively for the initiating terminal and the final phase of a project end of coil, and the middle section solderless wrapped connection of coil is on the stake body, the shell fragment draw close and connect in the lower part of the vertical wrapping post of stake body at the top surface of stake body and the borehole jack that cup joints on it, the mode that the riveting is passed through to the upper end of vertical wrapping post forms the flange of an outside extension, this flange is pressed in the solderless wrapped connection on the coil at vertical wrapping post top. Because the utility model discloses a flange at the vertical wrapping post top of stake body is pressed on the coil at solderless wrapped connection and vertical wrapping post top to reliably contact coil and shell fragment, form the electricity and connect, need not welding procedure, avoided the appearance of exploding the tin phenomenon.

Description

Voice coil motor coil brace structure with vertical wrapping post

Technical field

This utility model relates to a kind of digital camera, particularly relates to a kind of voice coil motor coil brace structure with vertical wrapping post.

Background technology

Known digital camera, mobile phone autofocus mechanism etc. on the voice coil motor that uses, make the lens carrier of holding lenticular body be moved along optical axis direction by the travel mechanism being made up of Magnet, coil and yoke.In this voice coil motor, the lens carrier outer peripheral face keeping lenticular body is adhesively fixed and is bunched to ring-type coil in advance, then worked by the magnetic field of the Magnet being fixed on yoke internal face, make lens carrier move along optical axis direction.In above-mentioned voice coil motor, owing to coil and shell fragment to realize conducting, conventional method is to use scolding tin to realize electrical connection, needs the soldering opening of a reserved/ending position initial with coil in existing structure on shell fragment, it is electrically connected after stannum on point, complex process.Meanwhile, having Colophonium in scolding tin, usually occur quick-fried stannum phenomenon in welding process, the stannum club produced hinders the smooth and easy movement of lens carrier, voice coil motor yields is reduced, to this end, industry is badly in need of a kind of technique of design simply, and can save the structure of welding process.

Summary of the invention

The purpose of this utility model is to provide the voice coil motor coil brace structure with vertical wrapping post that a kind of technique is simple, save welding step.

For achieving the above object, technical solution of the present utility model is:

This utility model is a kind of voice coil motor coil brace structure with vertical wrapping post, including stake body, shell fragment, coil；The middle part of described stake body has a centre bore, on the upper surface of stake body, the both sides of centre bore be correspondingly arranged a vertical wrapping post vertically upward respectively；The initiating terminal of coil and ending end are rotating around being connected on two vertical wrapping posts, and the stage casing of coil is around being connected on stake body；The both sides of described shell fragment offer a sleeve joint hole respectively, shell fragment abuts against the end face of stake body, sleeve joint hole is socketed in the bottom of the vertical wrapping post of stake body respectively, the upper end of vertical wrapping post forms a flange flexed outward by the way of riveting, and this flange is pressed on the coil being wire-wrapped in vertical wrapping post top.

The upper end of the described vertical wrapping post being wrapped with coil is pasted with glue.

Described it is wound around two circles around being connected on the coil segment that vertical wrapping post bottom contacts with shell fragment end face.

The described sleeve joint hole on shell fragment is square.

After using such scheme, owing to being provided with vertical wrapping post vertically upward on the upper surface of this utility model stake body, the initiating terminal of coil and ending end are rotating around being connected on two vertical wrapping posts, the sleeve joint hole of shell fragment is socketed in the bottom of the vertical wrapping post of stake body, the upper end of vertical wrapping post forms a flange flexed outward by the way of riveting, this flange is pressed on the coil at solderless wrapped connection and vertical wrapping post top, thus by coil and shell fragment reliable contacts, form electrical connection, without welding step, it is to avoid the appearance of quick-fried stannum phenomenon.

With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention

As shown in Fig. 1, Figure 1A, this utility model is a kind of voice coil motor coil brace structure with vertical wrapping post, including stake body 1, shell fragment 2, coil 3.

The middle part of described stake body 1 has a centre bore 11, on the upper surface of stake body 1, the both sides of centre bore 11 be correspondingly arranged a vertical wrapping post 12(vertically upward respectively as shown in Fig. 3, Fig. 4, Fig. 4 A).The initiating terminal 31 of described coil 3 and ending end 32 are rotating around being connected on two vertical wrapping posts 12, and the stage casing of coil 3 is around being connected on stake body 1；The both sides of described shell fragment 2 offer a sleeve joint hole 21 respectively, this sleeve joint hole 21 is square, shell fragment 2 abuts against the end face of stake body 1, sleeve joint hole 21 is socketed in the bottom (as shown in Fig. 5, Fig. 5 A, Fig. 5 B) of the vertical wrapping post 12 of stake body 1 respectively, the upper end of vertical wrapping post 12 forms a flange flexed outward 13 by the way of riveting, and this flange 13 is pressed on the coil 3 being wire-wrapped in vertical wrapping post 12 top (as shown in Fig. 6, Fig. 7, Fig. 7 A, Fig. 7 B).

The upper end of the described vertical wrapping post 12 being wrapped with coil 3 is pasted with the mushroom glue 4(of formation as shown in Fig. 2, Fig. 2 A).

In order to make shell fragment 2 relatively reliable with the electrical connection of coil 3 initiating terminal 31 and ending end 32, being wound around two circles (as shown in Figure 7 B) around being connected on initiating terminal 31 coil segment 311 that vertical wrapping post 12 bottom contacts with shell fragment 2 end face, ending end 32 coil segment 321 is wound around two circles (as shown in Figure 7 A).

Emphasis of the present utility model is that shell fragment uses the mode of a kind of riveting to be connected with coil.

The above, it is only this utility model preferred embodiment, the shape of shell fragment sleeve joint hole can have multiple, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
