Abstract

<P>PROBLEM TO BE SOLVED: To overcome a problem wherein a complicated work and many materials are needed for a plurality of connections because an operation fastening a bolt with a nut is needed after a platy connector, a washer and a spring washer are inserted into the bolt, when an electric device or a storage battery having a protrusive terminal is connected with the platy connector. <P>SOLUTION: In the platy connector 1, holes 2 for penetrating a terminal and protrusive portions 9, 9' having a spring function are arranged, and the protrusive portion is made of a part of the platy connector. <P>COPYRIGHT: (C)2003,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-like connector. 2. Description of the Related Art When connecting an electric device or a storage battery having a protruding terminal, a plate-shaped connection body has been often used. One example is shown in FIG. Reference numeral 1 denotes a plate-like connection body, and 2 denotes a terminal insertion hole. FIG. 2 shows, as an example, a state in which storage batteries are connected via a plate-like connection body.
Reference numeral 3 indicates a storage battery, 4 indicates a nut, and 5 indicates a bolt. FIG. 3 shows a state where a plate-like connector is inserted into a bolt and tightened with a nut.
2 is a hole for terminal insertion, 3 is a storage battery, 4 is a nut, 5 is a bolt, 6 is a washer, 7 is a spring washer, and 8 is a bushing. As described above, when connecting the storage batteries by inserting the plate-like connection body into the bolts inserted into the terminals, it is common to insert the washer 6 and the spring washer 7 and then tighten them with nuts. [0006] As described above, when a storage battery or the like is connected via a plate-like connecting body, it is necessary to insert a washer 6 and a spring washer 7 into a bolt and then tighten with a nut. Therefore, connecting a large number of storage batteries is a complicated operation. Also, many parts are required. According to the present invention, it is not necessary to insert the washer 6 and the spring washer 7, and the plate can obtain the same tightening torque as that when the washer 6 and the spring washer 7 are inserted simply by directly tightening the plate-like connection body with a nut. It is intended to provide a shape-like connection body. The present invention does not require the washer 6 and the spring washer 7 by providing the plate-like connector itself with a spring washer-like function. , A terminal insertion hole, and a projection having a spring function disposed on an outer peripheral portion of the hole, wherein the projection is formed by a part of a plate-shaped connection body. Things. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to embodiments. FIG. 4 is a front view and a sectional view of an embodiment showing a plate-like connection body according to the present invention, wherein 1 is a connection plate, 2 is a hole for inserting a terminal, and 9 and 9 'are 2 holes for insertion. Are formed integrally with the plate-like connector along the outer periphery of the protruding piece and protrude from the surface of the plate-like connector. With such a shape, when the plate-like connection body is inserted into the bolt inserted into the terminal and the nut is tightened, the protrusion acts as a spring washer on the lower surface of the nut, and the washer 6 Also, a sufficient torque can be maintained only by the nut without using the spring washer 7. [0010] In the embodiment, the plate-like connector is inserted into the bolt with the protruding piece facing upward. The same effect can be obtained because the projection acts as a spring washer. In the embodiment, the projecting pieces integrally formed on the plate-like connecting body project in the same direction. However, the same effect can be obtained by projecting the two projecting pieces in opposite directions. . As described above, the projecting piece having a spring function is formed integrally with the plate-like connection body along the outer periphery of the terminal insertion hole of the plate-like connection body, thereby making the plate-like connection possible. Even after the body is inserted into the raised terminal, the same torque as when using a washer and a spring washer can be maintained even when tightening only with the nut, reducing the number of parts and man-hours in the tightening work, and greatly increasing the industrial effect. is there.
