In order to solve the above problems, the electrolyte battery of the present invention press-fits an appropriately elastic resin or rubber insulator into the opening formed in the sealing body of the electrode can to prevent it from coming out. The shaft of the electrode terminal is hermetically inserted around the periphery and penetrated into the electrode can, and an end face perpendicular to the axis of the terminal and facing outside the can and an end face facing outside the can are attached to the outer peripheral surface of the shaft. A required number of narrow grooves each having a V-shaped cross section and a tapered surface that gradually increases in diameter are formed, and a part of the inner circumferential surface of the insulator is cut into the narrow grooves.

According to the above configuration, when the inner end of the shaft portion of the electrode terminal receives pressure inside the electrode can, the end surface of the thin groove formed on the outer circumferential surface of the shaft portion facing outside of the can becomes The narrow groove has a cross section of about V with a tapered surface that gradually becomes larger in diameter toward the outside of the can.
Because of the shape, it is easy to insert the shaft of the electrode terminal into the periphery of the insulator during assembly, and since the insulator is made of elastic resin or rubber,
As the pressure inside the electrode can increases, the load from the end face of the narrow groove increases, and the part that bites into the narrow groove finally deforms or breaks, and the electrode terminal comes out of the insulator, reducing the pressure inside the can. Open to the outside.

元力による食い込みを利用したものでも良い。 The electrolyte battery shown in Fig. 1 has a positive electrode and a negative electrode (both not shown) arranged insulated inside, and a stainless steel electrode can 1 filled with electrolyte is sealed with a sealing body 2 also made of stainless steel. A pin-shaped electrode terminal 3 is sealed via an insulator 4 to the opening 2a of the sealing body 2, which is fitted and bent with its peripheral edge 2b toward the inside of the can. The insulator 4 is made of Teflon (registered trademark) resin or rubber having appropriate elasticity, and a rib 4a integrally formed on the outer periphery of the inner end is connected to the opening 2a of the sealing body 2.
It is fixed to prevent it from coming off by abutting against the peripheral edge 2b of. As shown in an enlarged view in FIG. 2, the outer peripheral surface of the shaft portion of the electrode terminal 3 inserted into the inner periphery of the insulator 4 has an end surface 7a that is perpendicular to the shaft center and faces outside the can.
and a tapered surface 7b with a larger diameter on the outer side of the can.A required number (two in the axial direction in the illustrated embodiment) of narrow grooves 7 having a substantially V-shaped cross section are formed, and one part of the inner circumferential surface of the insulator 4 is formed. The portion is configured to bite into this narrow groove 7. The biting portion 4b on the inner periphery of the insulator 4 biting into the narrow groove 7 may be shaped in advance to correspond to the narrow groove 7, or may utilize biting due to the elastic restoring force of the insulator 4 during press-fitting.

易である。 In the electrolyte battery having the above configuration, the inner end surface of the shaft portion of the electrode terminal 3 is exposed to a load F on the outside of the can due to the pressure inside the electrode can 1.
When received, the end surface 7a of the narrow groove 7 formed on the outer circumferential surface of the insulator 4 engages with the biting portion 4 on the inner circumferential surface of the insulator 4.
However, since the insulator 4 is easily elastically deformed, the pressure inside the electrode can 1 increases and the load F from the end face 7a to the biting part 4b is reduced. As the pressure increases, the thrust direction support force of the biting part 4b to the electrode terminal 3 eventually reaches its limit, and the biting part 4b deforms or breaks and the electrode terminal 3 comes out from the inner periphery of the insulator 4, so that the pressure inside the can increases. can be opened to prevent the entire battery from exploding. In addition, when press-fitting the shaft portion of the electrode terminal 3 from the outside of the can into the inner circumference of the insulator 4,
The tapered surface 7b of the narrow groove 7 slides while elastically deforming the inner peripheral surface of the insulator 4 including the biting portion 4b toward the outer diameter, and the tightness of the insulator 4 relative to the electrode terminal 3 prevents leakage. Because it is not something to gain sex,
Press-fitting of the shaft portion of the electrode terminal 3 during assembly is easy.
なお、缶内圧力がどの程度まで上昇したときに

定可能である。 Note that the degree to which the pressure inside the can increases before the electrode terminal 3 comes out can be appropriately set by the size and number of the narrow grooves 7 or the interference of the insulator 4.

As described above, according to the present invention, excellent leakage resistance against the electrolyte in the electrode can is achieved by biting a part of the inner peripheral surface of the insulator into the narrow groove formed on the outer peripheral surface of the shaft portion of the electrode terminal. In addition, it is easy to insert the electrode terminal into the periphery of the insulator during assembly, and if the pressure inside the electrode case rises abnormally, it will not be damaged due to deformation or breakage of the biting part. Since the electrode terminal comes out and releases the pressure inside the can, it is possible to prevent the entire battery from bursting and improve safety.
