Description

  The present invention relates to a storage box structure for positive and negative electrode coplanar batteries, and in particular, each terminal bar of the battery storage body is operable via a spring, the head of this terminal bar is in contact with the battery, The present invention relates to a novel improvement for facilitating battery replacement by removing a portion of the battery from the battery housing body by the action of a spring.

Conventionally, as a battery storage box structure in which the negative electrode and the negative electrode are opposite to each other, a patent document or the like showing the structure is not shown, but the configuration shown in FIG. 4 is generally adopted.
That is, what is indicated by reference numeral 1 in FIG. 4 is a battery housing body for housing the battery 2, and a positive electrode 3 and a negative electrode 4 are formed at both ends of the battery housing body 1.
The negative electrode 4 is formed of a helical spring.

Since the conventional battery storage box structure is configured as described above, the following problems exist.
That is, a battery in which the positive electrode and the negative electrode are arranged on the same surface (CR-P2 type battery) cannot have the above-described conventional structure because the positive electrode and the negative electrode are in the same surface.
In addition, since the electrode is a spring, the contact area with the negative electrode of the battery is small and the electrical conduction is not good.

  The positive and negative electrode coplanar battery storage box structure according to the present invention includes a battery storage body provided in a mounting body having an opening, a pair of through holes formed in a rear wall of the battery storage body, A pair of terminal rods movably provided in each through hole via a spring, a head formed at the inner end of each terminal rod, and a lead wire connection formed at the outer end of each terminal rod And a step formed in the opening, and a cover body that is detachably provided on the step, and the battery is housed in the battery housing and the cover is mounted on the step The spring is in a compressed state, and the spring is located in the hole step formed in the through hole, and the lead wire connecting portion is formed with a screw. And the cover body is connected to the battery housing body. If you et removed, a structure part of the battery is to be pushed out of the opening, also the head is detachable from the terminal rod, a construction can be exchanged.

Since the storage box structure of the positive electrode and negative electrode coplanar battery according to the present invention is configured as described above, the following effects can be obtained.
In other words, when the battery of the positive electrode and negative electrode coplanar arrangement type is housed, the terminal rod provided on the battery housing body is pressed against the terminal part of the battery by the spring, so the contact with the battery is good and the contact failure is When the cover body is removed by the spring force of this spring, a part of the battery is pushed out from the opening, and the battery can be easily replaced.
Moreover, it can be set as the optimal shape matched with the electrode of the battery by replacement | exchange of a head.

  According to the present invention, the terminal rod provided in the battery housing body can be operated by a spring, and the cover body is detachably provided in the opening. The purpose is to ensure electrode contact.

Hereinafter, preferred embodiments of a storage box structure for positive and negative electrode coplanar batteries according to the present invention will be described with reference to the drawings.
In addition, the same code | symbol is attached | subjected and demonstrated about the same or equivalent part as a prior art example.
1, reference numeral 10 denotes a box-shaped mounting body having an opening 12 having a stepped portion 11. On the inner surface of the mounting body 10, a battery housing body 1 having a box shape as a whole is provided with a mounting screw. 13 is attached.

A pair of through holes 21 having hole step portions 20 are formed in the detachable rear wall 14 of the battery housing 1.
A terminal rod 23 is provided in each through-hole 21 via a spring 22 so as to be operable along the axial direction.

The terminal rod 23 is configured to be enlarged in FIG. 3, and a head 30 having a diameter larger than the diameter of the terminal rod 23 is integrally formed at an inner end 23a thereof, and an outer end thereof is formed. A lead wire connecting portion 32 made of a screw 31 is formed on 23b.
The lead wire connecting portion 32 is not limited to the screw 31, and other structures are possible.

The inner diameter of the spring 22 of the terminal bar 23 is set sufficiently larger than the outer diameter of the terminal bar 23, and a plurality of nuts 35 are screwed onto the screw 31.
The lead wire 40 and the terminal rod 23 are connected by sandwiching a crimp terminal 41 to which the lead wire 40 is connected between the nuts 35. Each terminal rod 23 and each head 30 constitute a positive electrode 3 and a negative electrode 4 corresponding to the conventional one.

In the battery housing 1, a positive electrode and a negative electrode coplanar arrangement type battery 2 corresponding to each terminal rod 23 and the head 30 (for example, a well-known CR-P2 type commercial product) is stored. A storage space 45 is formed, and a cover body 50 is detachably provided on the step portion 11 of the opening 12.
Each head 30 of each terminal rod 23 can be integrated with each terminal rod 23, but can be detachable and replaced with a shape that is optimal for the electrode shape of the battery 2 to be stored. It can also be configured to be able to.

  Next, after the battery 2 is inserted and mounted in the storage space 45 in the state of FIG. 1, the cover body 50 having the rubber plate 51 is attached to the step portion 11 of the opening 12, as shown in FIG. 2. Each terminal rod 23 is pushed into the back side by the battery 2 and the spring 22 is compressed.

  When the battery 2 is taken out after the mounting of the battery 2 described above, the battery 2 is pushed outward by the spring force of each compressed spring 22 by removing the cover body 50 from the opening 12. A part of the battery 2 jumps out of the opening 12, and the battery 2 can be easily taken out by hand.

  The present invention can be applied not only to a battery but also to a cartridge-like electronic unit.

1 is an exploded cross-sectional configuration diagram illustrating a storage box structure of a positive electrode and negative electrode coplanar battery according to the present invention. It is a cross-sectional block diagram which shows the state which accommodated the battery of FIG. It is an exploded view which shows the terminal rod of FIG. It is an exploded view which shows a conventional structure.
