After the terminal hole parts 8 of the terminal cover 7a are fitted over the terminals 2 of adjacent control valve type lead-acid batteries 1, the copper bar 3 is threadedly attached by bolts 4 to nuts 5 inserted in the terminals 2.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is made by connecting terminals of a plurality of adjacent control valve type lead-acid batteries in series using a connecting jig such as a copper bar. The present invention relates to a terminal cover for use in an assembled battery, for insulating and protecting the periphery of the terminal and the connection jig. 2. Description of the Related Art An assembled battery using a plurality of control valve type lead-acid batteries connected in series is characterized by being inexpensive and highly reliable, so that emergency power supply equipment such as an uninterruptible power supply is used. Widely used for. [0003] As shown in FIG. 3, a battery pack used for these uses a connection jig such as a copper bar 3 for a nut insert type terminal 2 provided in each control valve type lead-acid battery 1. , Bolts 4 were tightened with a spanner or the like to connect them in series. [0004] From the viewpoint of safety, after connecting each control valve type lead-acid battery 1 in series, the periphery of the copper bar 3 is covered with a U-shaped plastic terminal cover 7b, so that the terminal 2, copper A method of insulating the periphery of the bar 3 and the bolt 4 has been used. [0005] However, the work of attaching and detaching the copper bar and the bolt to and from the terminal of the above-mentioned lead-acid battery of control valve type using a tool such as a spanner is extremely troublesome. there were. In addition, during this operation, the terminal of another control valve type lead-acid battery may erroneously come into contact with a tool such as a wrench to cause a short circuit, and as a result, a spark may occur and an accident may occur. It was also a task. SUMMARY OF THE INVENTION It is an object of the present invention to provide a control valve-type lead-acid battery in which a connection jig such as a copper bar is attached to or detached from a terminal of the control valve-type lead-acid battery. It is to provide a terminal cover for a lead storage battery. [0008] In order to solve the above-mentioned problems, the present invention is to improve the above-mentioned terminal cover so that a connection jig such as a copper bar is connected to the terminal of the control valve type lead-acid battery. This facilitates the work of attaching and detaching, and prevents a short circuit during the work. That is, according to the present invention, a connecting jig is screwed and attached to a nut insert type terminal of an adjacent control valve type lead-acid battery by bolts, and the periphery of the terminal, the connecting jig and the bolt is insulated. What is claimed is: 1. A terminal cover for a control valve type lead-acid battery for protection, wherein said terminal cover is a box-shaped member having a bottom and no upper surface portion, and one side surface of which is adjacent to a control valve-type lead storage battery. And has two terminal holes for fitting over the terminal.After fitting the terminal hole into the terminal, the connection jig is screwed to the terminal with the bolt. It is characterized by being attached. An embodiment of the present invention will be described below in detail with reference to FIGS. (1) Terminal Cover FIG. 1 is a schematic view of a main part showing a connection state of a control valve type lead-acid battery 1 using a terminal cover 7a according to the present invention. The terminal cover according to the present invention has a box shape with a bottom and no upper surface. The terminal cover 7a is made of a transparent PET resin, and has two terminal holes 8 for covering and fitting the terminals 2 of the adjacent control valve type lead-acid battery 1 on one side surface. Have. In addition, control valve type lead-acid battery between different positions
Two voltage measurement holes 9 are provided corresponding to the positions of the terminal holes 8 so that the terminal voltage of 1 can be easily measured from the near side using a measurement pin or the like. (2) Attachment of copper bar and terminal cover As shown in FIGS. 1 and 2, the terminal 2 of the control valve type lead-acid battery 1 is covered with the terminal cover 7a and fitted. Insert copper bar 3. And the bottomed terminal cover 7a
The copper bar 3 is placed upright with the bottom plate of the copper bar 3 against the bottom plate.
Then, the bolt 4 was inserted from the near side of the copper bar 3, and the bolt 4 was screwed to the nut 5 inserted into the terminal 2 using a wrench (not shown) or the like. According to the present invention, the bolt 4 can be screwed onto the nut 5 inserted into the terminal 2 with the copper bar 3 standing on the bottom surface of the terminal cover 7a. it can. Also, when the copper bar 3 is attached or detached, the bolt 4 or the copper bar 3 is attached by the bottom plate of the terminal cover 7a.
Can be prevented from falling. In addition, when the copper bar 3 is screwed with the conventional bolts 4 and nuts 5 as shown in FIG. 3, a spanner or the like comes into contact with the terminal 2 of another control valve type lead-acid battery to short-circuit. Since there is no case to work, work can be performed safely. As described above, the terminal cover according to the present invention facilitates the work of attaching or detaching a connection jig such as a copper bar to or from a terminal of a control valve type lead-acid battery. It is excellent in safety because a tool such as a spanner does not contact a terminal of another control valve type lead storage battery to cause a short circuit.
