[TECHNICAL FIELD OF THE INVENTION]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery case applied to a mechanism such as a gas table provided with electronic device components such as an ignition circuit using a battery as a power source.

[Prior art]

Background Art Conventionally, it has been known that a front open case attached to a mechanism and a movable case freely detachable from the front in a fixed case for fixing a battery can exchange batteries in a state where the movable case is pulled forward.

When the negative electrode of the battery is fixed to the movable case to the rear, the coil spring attached to the contact bracket for the negative electrode formed at the rear end of the fixed case when the movable case is inserted into the fixed case. The negative electrode and the contact bracket of the battery are connected to each other by the spring terminal. In order to prevent the movable case from being pushed forward by the compression repulsive force of the spring terminal, the locking fixing means is formed so that the movable case is caught at a predetermined insertion position against the compression repulsive force of the spring terminal.

[Problems that the invention tries to solve]

In the battery case of the prior art, when no battery is attached to the movable case, the force from the spring terminal does not act on the movable case, and the 'arm' formed on one side and the other side of the movable case and the fixed case constituting the locking fixing means. There is a gap between the mating parts and the movable case is easy to swing. In addition, since the battery is not attached to the movable case at the time of shipment of the mechanism, when the purchaser unpacks and removes the mechanism, the movable case swings and a noise may occur, and the purchaser may be mistaken for a defective product. Therefore, in order to improve the merchandise, even if a battery is not attached to the movable case, it is preferable to prevent the swing of the movable case by applying a force to the movable case as a front.

In this case, an intermediate connecting bracket is formed at the rear end of the movable case, which extends in and out of the case, and a second spring terminal which contacts the negative electrode of the battery is attached to the inside of the case of the intermediate connecting bracket, and the outside of the case of the intermediate connecting bracket. The first spring terminal on the side of the fixed case is brought into contact with the negative electrode of the battery so as to be connected to the contact bracket of the fixed case via the second spring terminal, the intermediate connecting bracket, and the first spring terminal. Even if it is not, the swing of the movable case can be prevented by holding the movable case forward with the first spring terminal.

However, in the above example, even if the compression degree of any one of the first and second spring terminals is insufficient, contact failure between the battery and the contact bracket occurs, so that the battery to continuously compress the second spring terminal sufficiently in the movable case is provided. It is necessary to attach, and the force required for attaching a battery becomes large. In addition, since the intermediate connection bracket or two spring terminals are required, the number of parts increases, resulting in a cost increase.

SUMMARY OF THE INVENTION In view of the above, the present invention provides a battery case in which a moving force can be exerted on the movable case even when the battery is not installed in the movable case. Moreover, it is a subject to provide the battery case which reduced the number of components, and aimed at cost reduction.

[Means for solving the problem]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a battery case applied to a mechanism having an electronic device component using a battery as a power source, the front fixing case attached to the mechanism, and the battery fixed to and detachable from the front in the fixing case. A spring terminal comprising a coil spring for connecting the negative electrode at the rear end of the battery fixed to the movable case to the contact negative electrode for the negative electrode formed at the rear end of the fixed case when the movable case is inserted into the fixed case. And a battery case having a locking means for locking the movable case to a predetermined insertion position against the compression repulsion force of the spring terminal, wherein the spring terminal is in contact with the contact portion of the front end contacting the negative electrode of the battery and the rear end of the contact bracket. In the middle of the abutting part of the It can be prevented and it is equipped so as not to impede the transfer of power between yangmat abutment portion via the middle portion.

According to this, when the movable case is inserted into the fixed case with the battery mounted, the abutment portion of the rear end of the spring terminal abuts against the contact bracket of the fixed case, so that the spring terminal has a total length between the negative electrode of the battery and the contact bracket. Compression is ensured, and a degree of compression sufficient to prevent contact failure between the battery and the contact bracket is ensured.

Even if no battery is installed in the movable case, the spring terminal is compressed between the front end of the movable case rear end prevention portion and the contact bracket, which prevents the middle portion of the spring terminal from falling outwards. By means of the locking fixing means, the movable case is fixed to the predetermined insertion position without swinging.

In addition, when the battery is mounted by removing the movable case, the spring terminal is partially extruded from the front portion of the rear portion of the movable case to prevent the rear portion from slipping out of the rear portion of the movable case, so that the compression is less. Battery can be attached by force.

In addition, according to the present invention, the spring terminal is solved in one, and since the intermediate connecting brackets are unnecessary, the number of parts can be reduced and the cost can be reduced.

By the way, in the present invention, even if the movable member which is movable only in a predetermined stroke in the front-rear direction at the rear end of the movable case is fixed and the intermediate portion of the spring terminal is fixed to the movable member, the middle portion of the spring terminal is held in the movable case. Although the rear end portion can be prevented from falling out in the front-rear direction and prevented from interfering with the shear of the force between the two contact portions through the middle portion, the cost-effectiveness is halved due to the provision of the movable member.

On the contrary, the movable case is formed through a hole in the front of the pocket portion having holes in both front and rear sides, in which the spring terminal is formed into a substantially fusiform shape having a larger wound diameter in the middle portion, and the intermediate portion of the spring terminal is received at the rear end of the movable case. By protruding inward and projecting the abutting portion of the rear end of the spring terminal to the rear of the movable case through the hole at the rear of the pocket part, members other than the spring terminal are unnecessary and advantageous in cost.

In addition, two attachment portions 12d to the attachment bracket 5 are formed so as to cope with a change in the attachment position of the attachment bracket 5 according to the model of the gas table.

The movable case 20 is formed of a cover portion 21 at the front end corresponding to the open hole formed in the front panel 2, and a cover portion 21 rear surface. It is formed by integrally molding the resin frame 22 and the box-shaped battery housing 23 extending to the rear of the frame 22 with a resin. When the movable case 20 is inserted into the fixed case 10 by forming a portion 22a and attaching the terminal bracket 24 contacting the positive electrode of the battery E to the support pillar portion 22a, The positive electrode contact tool 13 is brought into contact with the upper end of the terminal fitting 24 engaged with the upper end of the column 22a.

The rear end portion of the battery storage portion 23 is provided with a contact portion 25a of the front end where the battery E abuts against the front end of the negative electrode and a rear end contact portion 25b which is in contact with the negative electrode contact bracket 14. A spring terminal 25 formed of one coil spring is formed, and when the movable case 20 is inserted into the fixed case 10, the negative electrode of the battery E passes through the spring terminal 25 for the negative electrode contact bracket ( 14).

The spring terminal 25 is in a state where the rear end of the battery storage portion 23 is prevented from falling back and forth in the middle portion 25c, and the contact portions 25a and 25b are connected through the middle portion 25c. It is mounted so as not to impede the transmission of force in the liver. In the illustration, the spring terminal 25 is formed in a substantially fusiform shape having a larger wound diameter of the intermediate portion 25c, and the intermediate portion 25c of the spring terminal 25 is formed at the rear end of the battery storing portion 23. The pocket part 26 which has the holes 26a and 26b of the front and back both sides to receive is formed, and the contact part 25a of the front end of the spring terminal 25 is connected to the battery storage part 23 through the hole 26a of the front side. In addition to protruding inwardly, the abutting portion 25b of the rear end of the spring terminal 25 is protruded to the rear of the battery storing portion 23 through the rear hole 26b.

As shown in FIG. 5 (a) between the battery and the battery E, it is compressed by L1. Then, when the movable case 20 is inserted into the fixed case 10, the spring terminal 25 is connected with the battery E. As shown in FIG. 5 (b), the compression degree of the spring terminal 25 is L1 + L2, and the battery E and the contact bracket ( 14) Good contact between them can be obtained. Since the compression degree of the spring terminal 25 when the battery is mounted on the movable case 20 is smaller than the final compression degree at L1, the battery E can be mounted with only a light force. The ratio of L1 and L2 can be set suitably, and by setting it as L1 / L21, the force required for attachment of the battery E can be reduced further.

When the spring terminal 25 is compressed as described above by the insertion of the movable case 20 into the fixed case 10, the movable case 20 is pushed forward by the compression repulsive force, so that the movable case 20 is inserted into the predetermined case. In order to secure the locking against the compression of the spring terminal 25 in the position, the locking means (27) consisting of a 'male / male' engaging portion on one side and the other side of the fixed case 10 and the movable case 20 is In the illustrated case, the tongue-shaped glass portion 27a extending from the bottom of the battery storage portion 23 into the mold portion 22 is integrally formed in the movable case 20.

It locks in place without swinging. And in this embodiment, even if the battery E is not attached to the movable case 20, when the movable case 20 is inserted into the fixed case 10, the spring terminal 25 removes the middle part 25c. As shown in Fig. 5 (c), between the front wall of the pocket portion 26 and the negative electrode contact bracket 14 which prevents the front portion from falling out, it is compressed by L2, and the movable case 20 is moved forward by this compression repulsion force. Is burnt. Thus, even when the purchaser unpacks the gas table packed without the battery E mounted on the movable case 20, the movable case 20 is fixed to the predetermined insertion position without swinging so that the movable case Occurrence of the joint by the fluctuation of (20) prevents the purchaser from mistaken the defective product.

At the time of battery replacement, it is necessary to release the jam of the movable case 20 and to take it forward. Thus, a hole 21a is formed at the front end of the glass portion 27a so as to form a rising portion 27d extending upward in the portion 22 and the upper portion of the rising portion 27d is formed in the lid portion 21. Protruding forward through the cover portion 21 is formed side by side as the finger catch portion (27e) with a gap in the lower portion of the handle portion 21b on the front of the cover portion 21, the grip portion (21b) with the finger catch portion (27e) At this time, the glass portion 27a is pulled up, the projection 27b is separated from the engagement hole 27c, and the locking of the movable case 20 is released.

When the locking of the movable case 20 is released in this way, the movable case 20 comes forward only by the compression degree L2 of the spring terminal 25, and the movable case 20 can be easily taken out. This is the same even when the battery E of the movable case 20 is not mounted, so the operation feeling is good.

In addition, at the rear end of the movable case 20, as shown in FIG. 4, a pair of locking projections 28 and 28 are formed on both sides of the pocket portion 26 to form the fixed case 10. As shown in FIG. 1 and FIG. 2, the inner surface of both sides of the case body 11 is shown. When the movable case 20 is pulled out to a position where the battery E can be mounted, the engaging projections 28 are formed by forming the projections 11b having a long length in the vertical direction that cooperate with the engaging projections 28. By engaging with each projection 11b, it is regulated that the movable case 20 is taken out further. The case body 11 is provided with a hole 11c which meets the upper end portion of each protrusion 11b, by inserting a tool into the hole 11c for maintenance, and pressing the locking protrusion 28 inward.
