Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a battery holder for a battery-powered watch or the like.

[Prior Art] Traditionally, the battery contact piece has been attached to the battery holder of a watch. The base end of the piece is passed through a through hole in a printed circuit board, and the penetrated base end and the printed circuit board are welded together with solder (Utility Model Publication No. 1989-89270).
etc. were hot. However, these require a complicated process for attaching the battery contacts, and a simpler assembly process has been desired.

Therefore, the battery contact piece is erected vertically within the frame body, brought close to the inner wall of the frame body, and the battery contact piece is resisted against the spring force by the protruding portion or retaining column formed integrally with the inner wall. one end of the battery contact piece is held in the upper case in this bent state, the other end of this battery contact piece is extended to protrude from the upper case, and is brought into contact with the inner wall of the battery storage chamber of the lower case; Furthermore, it was proposed that the upper case and the lower case be combined to safely hold the battery contact piece and the circuit board vertically disposed on the frame inside the case (Kokuko Sho 54-26227).

[Problem to be solved] However, in this example, the battery contacts cannot be stably held unless both the upper and lower cases are used, and since the inner wall of the case is used, If the battery holder is provided in a position that is not close to the battery holder, the battery contact piece cannot be held. Furthermore, since it is necessary to form a protrusion on the case, the manufacturing cost is increased and the shape of the battery contact piece is also complicated.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a battery holder in which a battery contact piece can be easily held in any position on one case, which can be easily attached and detached, and whose frame can be easily formed and assembled.

[Means for Solving the Problems] The present invention is characterized by a battery contact piece provided perpendicularly to the bottom surface of the frame body, a holding protrusion that holds the battery contact piece in a predetermined position, and a battery contact piece provided perpendicularly to the bottom surface of the frame body. The battery contact piece consists of a horizontally disposed circuit board, and the battery contact piece is formed by bending a conductive plate material into an L-shape in the thickness direction to form a vertical contact piece part and a horizontal contact piece part, and an end of the horizontal contact piece part. is formed with a fork-shaped portion, and the holding protrusion is vertically provided from the bottom surface of the frame body and comes into contact with both sides of the vertical and horizontal contact pieces of the battery contact piece, and the holding protrusion The ends of the substrate are in engagement with the forked portions of the cell contacts.

[Examples] Examples of the present invention will be described below with reference to the drawings.

In FIG. 1, a battery holder 2 is provided on a front frame 1 of a timer, etc., and the configuration of this battery holder is such that conductive plates are bent in an L-shape in the thickness direction at both ends of the battery holder. Battery contact pieces 3 and 4 are vertically provided facing each other on the bottom surface 2a of the front frame.

Vertical contact pieces 3a, 4 of battery contacts 3, 4, respectively
a are facing each other, and each horizontal contact piece part 3
b and 4b are close to each other, and bifurcated portions 3c and 3c are formed at the ends of the horizontal contact pieces, as shown in the third figure.

Next, the structure of the holding contacts 5, 6, 7, and 8 that hold the battery contacts 3 and 4 in predetermined positions will be explained.

The holding protrusions 5 to 8 are vertically arranged from the bottom surface 2a of the front frame 1, and are attached to both sides of the L-shaped vertical and horizontal contact pieces 3a, 3b, 4a, and 4b of the battery contacts 3 and 4, respectively. It comes into contact with.

Its specific configuration is that plate-shaped holding protrusions 5 are in contact with both sides of the vertical contact piece 3a of one battery contact piece 3.
a, 5b, a plate-shaped holding protrusion 6a and a rod-shaped holding protrusion 6b, which are in contact with both sides of the horizontal contact piece 3b.
6b. Also, the other battery contact piece 4
plate-shaped holding protrusions 7a, 7b that are in contact with both sides of the vertical contact piece part 4a; a plate-shaped holding protrusion 8a and a bar-shaped holding protrusion 8 that are in contact with both sides of the horizontal contact piece part 4b;
b, 8b.

Therefore, the positioning of the battery contacts 3 and 4 in the horizontal direction (horizontal direction in FIG. 1) is determined by the vertical contact parts 3a,
Holding protrusions 5a, 5b, 7a, which are in contact with 4a,
7b, and the vertical positioning of both battery contact pieces 3 and 4 (in the vertical direction in FIG.
b, 6c, 8a, 8b, 8c.

Furthermore, a mechanism for preventing the battery contacts 3 and 4 from coming off toward the opening end of the front frame 1 (toward the left in FIG. 3) will be described.

The circuit board 13 is provided horizontally on the bottom surface 2a of the front frame 1, and the ends of this circuit board are formed at the ends of the horizontal contact pieces 3b, 4b of the battery contacts 3, 4. It is engaged with certain bifurcated portions 3c, 3c (shown in the third figure). This engaged state is as shown in the first and third figures. In addition, in FIG. 3, the bifurcated portion 3c,
3c shows only the shape bored in the horizontal contact piece 3b of one battery contact piece 3, but the horizontal contact piece 4b of the other battery contact piece 4 also has a bifurcated part 3c, A bifurcated portion having the same shape is bored in a position facing 3c.

The battery contacts 3 and 4 are connected to a predetermined circuit pattern on the circuit board 13.

Battery receiving ribs 9 and 10 are erected perpendicularly from the bottom surface 2a of the battery holder 2 along the direction in which the battery is inserted. Also, the battery holder 2 is placed along the outer peripheral surface of the battery.
Wall parts 11 and 12 are vertically arranged on the bottom surface 2a, and the front frame 1 is connected to a rear frame 14, and a small battery cover 15 is fitted to the rear frame.

Therefore, in order to assemble the battery holder 2, first attach the ends of the circuit board 13 to each horizontal contact piece 3 of the battery contact pieces 3 and 4.
The circuit board 13 is fixed to the front frame 1 by fitting it into the forked portions 3c and 3c of the battery contacts 3b and 4b, and pushing the battery contact piece down vertically from above onto the holding protrusions 5 to 8 and inserting it between the holding protrusions. Bye. To take it out, conversely, it is sufficient to release the circuit board 13 from the front frame 1, pull up the battery contacts 3 and 4 vertically, and then pull out the circuit board horizontally.

To attach and detach the battery, the battery is inserted by sliding the receiving ribs 9 and 10 extending along the direction in which the battery is inserted.

[Effects] In the present invention having the above configuration, since the holding protrusion is vertically provided from the bottom surface of the frame body, the mold for forming the battery holder is simplified, the formation is easy, and the manufacturing cost can be reduced. Further, the L-shaped battery contact piece is positioned by the holding protrusion and the circuit board, and its movement in all directions is restricted, and at the same time it is easy to assemble. Furthermore, even when the battery holder is provided in a part of the case of a battery-powered device, it can be provided anywhere on the case, for example, in the center, which increases the degree of freedom in placement.
