China Patent No. CN200510055839.6 discloses a kind of design of being convenient to spring terminal and shell installation, better to raise labour productivity.This design is by the some accepting holes of design on shell, at the corresponding some lug bosses of elasticity binding post standing part design, accepting hole in when assembling with the corresponding shell of jut of elasticity binding post, carry out pressing then, like this, the elasticity binding post is just realized assembling by lug boss and combining of accepting hole.Though this design has solved all bad of elasticity binding post and shell one injection moulding generation technically, improved labor productivity to a certain extent, but this technology easily causes loose contact in the pressing process, and the elasticity binding post is not tight with combining of shell, is easy to generate drawback such as come off.Therefore, be necessary further improvement to such scheme.
The utility model content
Technical problem to be solved in the utility model provides a kind of termination of miniature moving-coil type electroacoustic transducer, to overcome the defective of original miniature electro-acoustic transducer elasticity binding post assembling, reduce technology difficulty, avoid defectives such as loose contact, improve the production efficiency of assembling.
For solving the problems of the technologies described above, the technical solution of the utility model is: the termination of miniature moving-coil type electroacoustic transducer, the plastic casing that comprises electroacoustic transducer, at least two elastic metallic binding posts are installed on the described shell, described binding post is " U " shape, and: described shell is provided with the hole that holds that described binding post is installed, the blind end of described binding post inserts the described hole that holds, and a branch of the openend of described binding post stretches out as the external electrode part and holds hole and exceed described shell plane.Thisly hold hole by design on shell, thereby in assembling, the blind end of binding post can be inserted and hold hole, a branch of the openend of binding post stretches out as external electrode and holds hole and exceed described shell plane, thereby after miniature moving-coil type electroacoustic transducer is assembled to electronic product, the external electrode of binding post is crimped on the electronic product by elasticity, realizes that the assembling of miniature moving-coil type electroacoustic transducer is installed; The more important thing is that the binding post of this structure is inserted into to be installed to and holds in the hole, assembling is simple, efficient is high, and binding post is received hole constraint location, good reliability.
As a kind of improvement, another branch of the described relatively branch as external electrode of described binding post is provided with hangnail, the described holding part that is provided with corresponding described hangnail in the hole that holds.
As a kind of further improvement, the elastic strip body of described hangnail for forming through punching press.This processing technology by elastic strip body is simple, and fixed performance is good.
As a kind of further improvement, described hangnail is one or more.The quantity that can change hangnail as required satisfies the design requirement different to the elasticity arrangements of electric connection with change in location.
As a kind of further improvement, the described hole that holds is two, and symmetrical being located on the described shell.
As a kind of further improvement, described holding part is described depression, hollow out or the projection that is provided with in the hole of holding.
As a kind of further improvement, describedly be provided with salient point as external electrode.
As a kind of improvement, described miniature moving-coil type electroacoustic transducer is square.The preferred square miniature electro-acoustic transducer of the technical solution of the utility model, other shapes such as circle etc. also can be used certainly.
Owing to adopted technique scheme, the assembling process of elasticity binding post and shell is simple to operation more, and switching performance is good, has avoided defectives such as the complex process that produces in the technical processs such as one injection moulding, pressing and loose contact, reduce production cost, improved production efficiency.

Embodiment
As Fig. 1-shown in Figure 4:
A kind of termination of miniature moving-coil type electroacoustic transducer comprises the plastic casing 1 of electroacoustic transducer being equipped with two on the shell 1 " U " shape elastic metallic binding post.
Shell 1 is a rectangle plastics shell, at the major axis two ends of shell 1, is symmetrically arranged with two and holds hole, holds hole by in case surface groove being set, and is coated with top cover 12 on the groove and constitutes.Binding post comprises two branches and the crooked blind end 23 that is connected two branches.Thereby binding post can insert blind end 23 in groove, be received hole and limit, and two branches of binding post and hold Elastic Contact between the hole.This fit is simple, the production efficiency height.
First branch is fixed on the lead-in wire that is used for connecting electroacoustic transducer inside on the shell 1, the second branch part is stretched out and is held hole, and exceed the surface of shell 1, thereby after miniature moving-coil type electroacoustic transducer is being installed to electronic product inside, local and the electronic product Elastic Contact of second branch guarantees to be electrically connected.
First branch comprises a hangnail 211, hangnail 211 is set on the main part 212 of first branch, the end of main part 212 also is provided with connecting portion 213, and connecting portion 213 and main part 212 be not on a horizontal plane, and connecting portion 213 also is connected with a planar portions 214.Binding post is installed to shell 1 hold hole after, on the bottom 11 of main part 212 attached to groove; Hangnail 211 is the elastic opening that main part 212 forms through technologies such as punching presses, and its opening direction is consistent with the opening direction of binding post branch; The position of channel bottom 11 and hangnail 211 correspondences is provided with holding part 13, holding part 13 is depressions that are provided with on the channel bottom 11, thereby binding post be installed to hold hole after, the elasticity of hangnail 211 obtains discharging, be snapped in the holding part 13, can prevent that binding post from coming off from hold hole; Connecting portion 213 and planar portions 214 combine attached on the shell 1, and and main part 212 not on a horizontal plane, can effectively strengthen the bond strength between first branch and the shell 1; Planar portions 214 areas are bigger, can be used for connecting the lead-in wire of electroacoustic transducer inside, and the connection design of lead-in wire and the part of electroacoustic transducer inside are installed and belonged to known technology, and do not influence the novelty and the creativeness of this patent, do not repeat them here.
Second branch comprises main part 221 and bend 222, also is provided with salient point 223 on the bend 222; Main part 221 is limited by the top cover 12 on groove top on the shell, bend 222 parts are stretched out and are held hole, and exceed the surface of shell 1, after electroacoustic transducer was installed to electronic product, the salient point 223 on the bend 222 can be connected with electronic product elasticity preferably.
Certainly, as the common engineers and technicians in this area, described hangnail 211 can be one or more.Equally, holding part 13 can be depression, hollow out or the projection that is provided with in the accommodation hole hole.Shell 1 surface is provided with groove, thereby and be coated with on the groove top cover 12 form the design of holding hole can appropriate change, its aim is to be beneficial to the insertion of binding post and to be convenient to fixing get final product of binding post in holding hole.
The art of this patent scheme comparatively is applicable to a rectangular electroacoustic transducer, in fact also can adopt in the electroacoustic transducer of other shapes; " U " shape metal connection terminal is meant end sealing, and the elongated shape structure of other end opening is not to refer in particular to " U " " elastic sheet metal of font, should be understood to adopting by equation as Approximate Design schemes such as " V " shapes to this patent.
