Problems solved by technology

[0016] The above-mentioned existing problems can be solved through the development of such a quick snap-fit ​​electrical connector, but since the connector is smaller than the battery, it is not easy to see clearly during disassembly and assembly, and sometimes the center position of the male and female connector parts is displaced, The engaging part may be damaged, and it is necessary to further improve the operability during engaging
In addition, when dust or liquid adheres to the connector or its terminal connection part, the resistance increases or the conductivity fluctuates, which easily affects the good electrical connection. Therefore, it is also necessary to improve the dustproof and waterproof aspects.

Embodiment

[0147] Below, according to the attached Figure 1 While describing various embodiments of the present invention, the present invention will be described in more detail.

[0148] First, refer to figure 1 and figure 2 A basic embodiment of an electrical storage device in which the connector of the present invention can be suitably used will be described.

[0149] This power storage device is, for example, a large capacitor constituted by a plurality of electric double layer capacitor cells (battery batteries), and is used as a supercapacitor of a power storage power supply device of an electric vehicle.

[0150] Such as figure 1 As shown, the power storage device 1 has a frame body 2 and a power storage module 3. The frame body 2 has a storage space inside; the power storage module 3 is housed in the frame body 2 and has a large power storage capacity.

[0151] The storage battery module 3 has a capacitor unit (storage battery) 20, a bus bar 4, a binding plate (enclosed wit...

Deformed example 1

[0192] Refer to the following Figure 9 Modification 1 of the connector of the present invention will be described.

[0193] The basic structure of Modification 1 is the same as that of the connector 30 described in the first embodiment, but this Modification 1 is characterized by the female thread portion provided on the inner ring portion. In the following description, although the male connector part is used as an example, it is also applicable to the female connector part.

[0194] Figure 9 The male connector part 40a of the illustrated connector 30 has a base portion 41 , an outer ring portion 42 and an inner ring portion 45 .

[0195] A female thread portion 46 is provided on the inner peripheral surface of the inner ring portion 45 . Further, a groove 47 is recessed in the inner peripheral surface of the inner ring portion 45 in the axial direction (cylindrical axis direction) of the inner ring portion 45 . The grooves 47 are provided at predetermined intervals, fo...

Deformed example 2

[0200] Refer to the following Figure 10 Modification 2 of the connector of the present invention will be described.

[0201] The basic structure of Modification 2 is the same as Modification 1, but Modification 2 is characterized by having a handle portion. In addition, in the following description, although the male connector part is used as an example for description, it is also applicable to the female connector part.

[0202] Figure 10 The male connector part 40b of the illustrated connector 30 has a base portion 41, an outer ring portion 42, and an inner ring portion 45 having an internal thread portion 46 and a groove 47 formed by roll forming on the inner peripheral surface thereof.

[0203] exist Figure 10 In the upper end portion of the inner ring portion 45, a handle portion 48 protruding radially is provided. The handle portion 48 is formed in connection with the groove 47, and three are provided at intervals of 120°.

[0204] Here, a method of forming the h...

Abstract

PROBLEM TO BE SOLVED: To provide connection structure of a storage element capable of flowing large current, without mentioning the capability of improvement in the workability in connection of two or more elements, as well as the reduction in production cost.SOLUTION: The storage elements are connected each other by mutually abutting on countering end surfaces in the direction of an axis of inner side cylinders 41 and 51 of a male side electrical connection hook 22 and a female side electrical connection hook 32, and also by pressure-welding the circumference surface of an outside cylinder 42 of the male side electrical connection hook 22, and the inner circumference surface of an outside cylinder 52 of the female side electrical connection hook 32. In this way, the male side electrical connection hook 22 and the female side electrical connection hook 32 can be detached and attached with a single touch. A current path is formed between the end sides mutually abutted by the inner side cylinders 41 and 51 of the male side electrical connection hook 22 and the female side electrical connection hook 32, and furthermore a current path is formed between the circumference surface of the outside cylinder 42 of the male side electrical connection hook 22 and the inner circumference surface of the outside cylinder 52 of the female terminal.

Description

technical field [0001] The present invention relates to a connector for electrically connecting terminals and wires, and more particularly, to a quick-fit connector.
