Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a connection terminal structure for a laminated dry cell battery that allows easy battery replacement.

(Prior Art) Fig. 3 shows an example of the conventional connection terminal structure of a laminated dry battery (type S-006P in JIS, type 6F22 in 1EC), which is a type of manganese dry battery.

As shown in Fig. 3, the positive terminal 2 of the stacked dry battery 1 has a simple cylindrical shape, while the negative terminal 3 has an enlarged cylindrical tip and a plurality of vertical slits. is configured to be elastically expandable. On the other hand, in the connection terminal structure electrically connected to the terminals 2 and 3, the negative electrode 4 has a simple cylindrical shape, and the negative terminal 3
can be inserted into the cylinder of the negative terminal 3 while expanding its diameter through elastic deformation, and the positive electrode 5
The cylindrical tip is bent inward and a plurality of slits are provided in the vertical direction so that the tip can be elastically expanded, and the positive terminal 2 can be inserted into the cylinder while expanding this cylindrical shape by elastic deformation. . These negative electrodes 4 and positive electrodes 5 are
It is integrally fixed to the insulating base member 6, and the electrodes 4,
Power supply lines 7 and 7 are connected to the terminals 5 and 5, respectively. This connection terminal structure is generally called a battery snap.

In the above-described conventional connection terminal structure for a laminated dry battery, the positive terminal 2 and the positive electrode 5 come into elastic contact with each other due to the elastic deformation of the positive electrode 5 to establish an electrical connection, and the elastic deformation of the negative terminal 3 causes the positive terminal 2 and the positive electrode 5 to come into elastic contact. The negative electrode 4 and the negative terminal 3 come into elastic contact with each other due to elasticity, thereby establishing an electrical connection. Therefore, in order to obtain a more reliable electrical connection, the elasticity of the negative terminal 3 and the positive electrode 5 must be large. If they are brought into elastic contact with weak elasticity, there is a risk that the terminals 2, 3 and the electrodes 4, 5 may separate due to vibration or the like.

For this reason, when replacing the battery, it is necessary to pull the insulating base member 6 on which the electrodes 4 and 5 are provided from the stacked dry battery 1 with a strong force in the direction of separation. In the connected state, the insulating base member 6 is close to the stacked dry battery 1, and a nail can be inserted into the gap to pry it open. Therefore, there were problems in that changing the battery easily damaged the nails, and it was difficult for women and children who were weak to do so. Furthermore, since the insulating base member 6 is pulled with a lot of force, the force cannot be controlled well, and the terminal 2,
At the same time as the electrodes 4 and 5 are separated from the battery 3, the insulating base member 6 is separated from the stacked dry battery 1 by a large distance, and a strong force is applied to the power supply lines 7 and 7, causing them to be easily disconnected.

Therefore, a technology to make it easier to replace stacked dry batteries 1 is disclosed in Japanese Utility Model Laid-Open Publication No. 118658/1983. Simply put, this device is composed of a battery storage section that has a sloped surface that can guide the rear of the battery and a vertical surface below the sloped surface, and a plate that is placed in the battery storage section and has electrodes formed thereon to which the positive and negative terminals of the battery are connected by the pressing force of a spring.

Also, Utility Model Application No. 53-65521 and Utility Model Application No. 57-
No. 199950 discloses techniques for preventing stacked dry batteries from being stored in the battery compartment with the wrong polarity, but in both cases, the battery compartment is provided with a spring that presses the rear of the battery. The terminals of the battery are connected to each electrode by the pressing force of this spring.

(Problem to be solved by the invention) The technology shown in Utility Model Application No. 58-118658 mentioned above is superior in that it is possible to easily remove the battery by hooking your finger on the rear part of the battery and pulling it up. However, a space sufficient to form the slope surface is required, and the battery storage section becomes correspondingly large. In cases where electronic devices and the like are designed to be made smaller in size, there is a strong demand for smaller battery compartments.

In addition, in the technology shown in Utility Model Application No. 53-65521,
It is inconvenient to replace the battery because it is necessary to insert a nail or the like into the narrow gap between the rear part of the battery and the spring in the battery storage part to pull up the battery. In addition, Mikiakiaki
In the technique of No. 57-199950, the battery must be pulled up by inserting a nail or the like into the narrow gap between the rear part of the battery and the spring in the battery housing, or by grasping the battery itself. It is not universally possible to form the battery storage portion so that the battery itself can be held.

The present invention was developed to solve the above-mentioned problems of the conventional technology, and although the space is small in the battery compartment, it is easy to replace the battery, and it is designed to prevent connections with incorrect polarity. An object of the present invention is to provide a connection terminal structure for a laminated dry cell battery.

(Means for Solving the Problem) In order to achieve the above object, the connection terminal structure for a laminated dry battery of the present invention includes a movable member made of an insulating material on the terminal side of the laminated dry battery to be stored in the battery storage part. is disposed so as to be movable in contact with and separate from the terminal, and this movable member is elastically biased toward the terminal by an elastic member, and the movable member is attached to the bottom end of the battery storage section to An operating part is provided in the battery storage part to be engaged with the battery storage part so as to be able to swing or retreat against the elasticity, and to allow the user to hook the free end of the operating part to swing or retreat against the elasticity; Connecting electrodes made of a conductor are arranged in a mutually insulated state on the movable member facing the positive terminal and negative terminal of the laminated dry battery, respectively, and a protrusion made of an insulating material is provided around the connecting electrode facing the positive terminal. A dimension surrounded by the protrusion is set to be larger than the outer diameter of the positive terminal and smaller than the outer diameter of the tip of the negative terminal, and power supply lines are electrically connected to the connection electrodes.

(Function) By moving the movable member on which the connecting electrode is arranged with a finger or the like against elasticity, the connecting electrode and the terminal are separated, and the stacked dry battery can be stored in or removed from the battery housing. It can be taken out. Then, when the finger or the like is released, the connection electrode of the movable member comes into elastic contact with the terminal of the stacked dry battery housed therein, thereby establishing a reliable electrical connection. At this point, the movable member, which is equipped with a connecting electrode that comes into contact with the terminal of the battery with elasticity, is moved with a finger or the like against the elasticity to remove the battery. There is no need to insert the battery, it is easy to take out the battery, and the space in the battery compartment does not become large. Moreover, because of the protrusion made of insulating material provided around the connection electrode facing the positive terminal, if the stacked dry battery is inserted in the wrong direction, the terminal will not come into elastic contact with the connection electrode.
There is no risk of incorrect polarity connection.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a partially cutaway perspective view of the connection terminal structure for a stacked dry battery according to the present invention, and FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1.

In FIGS. 1 and 2, a battery storage section 10 for storing a stacked dry battery 1 is formed in a part of a resin housing of an electronic device or the like. In this battery storage section 10, a movable member 1 made of an insulating material such as resin is provided on the terminals 2 and 3 side of the stacked dry battery 1 to be stored, so that it can freely come into contact with and separate from these terminals 2 and 3.
1 is arranged. Elastic arms 12, 12 are provided on both sides of the lower part of the movable member 11 (bottom side of the battery storage section 10).
Protrusions 13, 13 are provided to protrude outward from each other. Further, while forming the battery storage part 10, an engaging elongated hole 1 is provided in the side wall facing the protrusions 13, 13.
4 and 14 are drilled with their long diameters aligned with the moving direction of the movable member 11. Then, due to the elastic deformation of the arms 12, 12, the protrusions 13, 13 engage with the elongated holes 14, 1.
4 and the movable member 11 is inserted into and engaged with the battery storage section 1.
0, so that it can swing and retreat freely, and is prevented from falling off. Note that the upper end (free end) of the movable member 11 is hung with a finger or the like, and the movable member 1 is
A protruding operating portion is provided for swinging or retracting the device 1 against elasticity. Further, on the surface of the movable member 11 on the terminal 2, 3 side, connection electrodes 15, 16 made of a conductor are arranged in a mutually insulated state so as to face the terminals 2, 3, respectively, and one end of each is movable. Terminals 17 and 18 are protruded from the back surface of the member 11 (ie, the surface opposite to the terminals 2 and 3 side) and also serve as fixing members, and power lines 19 and 19 are connected to these terminals 17 and 18. Furthermore, around one of the connection electrodes 15 facing the positive terminal 2, protrusions 20 made of an insulating material and convex toward the terminal 2 (in FIG. ) will be provided.

Here, the outer diameter of the positive terminal 2 of the stacked dry battery 1 is
d ₁ is smaller than the outer diameter d ₂ of the tip of the negative terminal 3.
Therefore, the dimension D surrounded by the protrusion 20 is set to be larger than d ₁ and smaller than d ₂ so that only the positive terminal 2 can come into contact with the connection electrode 15 and the negative terminal 3 cannot.

Furthermore, a spring fixing part 21 consisting of a circumferential protrusion is formed on the back surface of the movable member 11, and a spring positioning protrusion 22 is formed on the side wall forming the battery storage part 10 opposite thereto. And the spring fixing part 2
1 and the spring positioning protrusion 22, both ends of which are positioned, and the spring spring 23 is compressed. Note that a restricting protrusion 24 is formed on the side wall of the battery storage portion 10 to restrict the range in which the movable member 11 moves toward the terminals 2 and 3 due to the elasticity of the spring spring 23.

In this configuration, if the stacked dry cell battery 1 is not stored in the battery storage section 10, the movable member 11 is pressed against the restriction ridge 24 and its movement is restricted by the elastic bias of the spring spring 23. . Further, the protrusions 13, 13 are engaged with the elongated holes 14, 14.
Since it is inserted into and engaged with, it will not fall off. When storing the laminated dry cell battery 1, the movable member 11 is moved against the elasticity of the spring spring 23 using a finger or the like, and the laminated dry cell battery 1 is stored in the battery storage part 10. When the laminated dry cell battery 1 is released, the movable member 11 is moved. The member 11 moves due to the elasticity of the spring spring 23, and the connecting electrode 1
5 and 16 come into elastic contact with the terminals 2 and 3, respectively, to ensure electrical connection. Here, the laminated dry battery 1
If the insertion direction is incorrect, the protrusion 20 around the connection electrode 15 will cause the negative terminal 3 to be inserted into the connection electrode 1.
5, so there is no possibility of erroneous connection. Moreover, if the protrusion 20 is provided around the connection electrode 15 and between the connection electrode 16 and the connection electrode 16 as shown in FIG. 1, the terminals 2 and 3 will not shift and come into elastic contact with the connection electrodes 15 and 16. In particular, if the connecting electrode 15 is surrounded on three sides by the projections 20, the positive terminal 2 that comes into elastic contact with the connecting electrode 15 can be easily positioned. Furthermore, when taking out the laminated dry battery 1, the movable member 1 must be pressed against the elasticity of the spring spring 23 with a finger or the like.
1 and connect electrodes 15, 16 and terminals 2, 3.
The stacked dry battery 1 can be taken out by separating the stacked dry battery 1, and the stacked dry battery 1 can be easily replaced using a finger or the like. Moreover, there is no need to enlarge the battery storage section 10.

In the above embodiment, the movable member 11 is elastically biased by the spring spring 23 as an elastic member, but the present invention is not limited to this. The movable member 11 may be elastically biased toward the terminals 2 and 3 by protruding an arm or the like. Also, protrusion 1
3 and 13 and the engaging elongated holes 14 and 14 prevent the movable member 11 from falling off, but the structure is not limited to this.

(Effects of the invention) As explained above, according to the connection terminal structure for a laminated dry cell battery of the present invention, the laminated dry cell battery can be easily replaced by moving the movable member with a finger or the like against the elastic bias. I can do it. The force for moving the movable member is weaker and more sufficient than that of the conventional battery snap, which is a connection terminal structure for laminated dry batteries, and does not damage nails, etc., and is suitable for women and children with weak physical strength. However, battery replacement is easy. moreover,
The battery can be removed by moving the movable member, which is equipped with a connection electrode that makes elastic contact with the battery terminal, with a finger or the like against the elastic force, making it easy to remove the battery, while requiring extra space behind the battery. without,
The space in the battery compartment does not become large,
It is suitable for downsizing the housing of electronic equipment. Further, the movable member only moves within the battery housing, and there is no risk of pulling and breaking the power line or the like. Furthermore, if the laminated dry battery is inserted in the wrong direction, the terminal will not be able to make elastic contact with the connecting electrode due to interference from the protrusion, and it has the excellent effect that it will not be connected with the wrong polarity. .
