Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric connector for a battery, which electrically connects two electric wires to one electrode of a battery of an automobile or the like.

[0002]

[Prior art]

 FIG. 3 shows a conventional electrical connector for batteries similar to the one described in Japanese Utility Model Laid-Open No. 51-115482. In the figure, reference numeral 1 is a main body which is crimped to a battery electrode and has an electrode insertion hole 3. The main body 1 has a pair of fastening pieces that face each other across the groove, and by fastening them together by fastening means 5, they are crimped to the battery electrode. A connecting plate 7 is integrally formed on the main body 1, and a stud bolt 9 is provided on the connecting plate 7. Then, the stud bolt 9 is fitted with the terminal fittings 11 and 13 with the wires W1 and W2 being swaged at one end, respectively, and the nut 15 is tightened, so that the two wires W1 and W2 are connected to the battery electrode. To connect.

FIG. 4 shows a conventional electrical connector for batteries similar to that described in Japanese Utility Model Laid-Open No. 55-136164. In the figure, reference numeral 21 is a main body portion 21 which is curved and formed in a U shape so as to fit into the battery electrode. The main body portion 21 has a pair of fastening pieces 23 and 25, which are fastened to the battery electrode by fastening them with a bolt 27 and a nut 29. The electric wire W1 is crimped to the one clamping piece 23. Reference numeral 31 is a separately designed terminal piece, and this terminal piece 31 is provided with a tab terminal 33 for connecting another electric wire (not shown). Then, the terminal piece 31 is fastened together with the fastening pieces 23 and 25 together with the bolt 27 and the nut 29, thereby connecting a plurality of electric wires to the battery electrode.

[0004]

[Problems to be solved by the device]

 By the way, in the conventional example shown in FIG. 3, since the two terminal fittings 11 and 13 are connected to the main body portion 1 by tightening the nut 15 on the stud bolt 9, especially when the electric wires W1 and W2 are thick, the nut tightening is performed. The work is troublesome. Further, since the terminal fittings 11 and 13 are electrically connected to the main body portion 1 by the contact pressure when the nut 15 is tightened, it is not suitable for passing a large current.

Further, in the conventional example shown in FIG. 4, since the electric wire is electrically connected via the tab terminal 33, it is also unsuitable when a large current is passed. Further, in this conventional example, it is conceivable to further extend the fastening piece 25 on the other side and crimp another electric wire thereto, but it requires labor such as bending the main body portion 21 after crimping. So it is not good for work.

The present invention has been made in view of the above circumstances and has an object to provide an electric connector for a battery, which allows easy crimping of two electric wires and is suitable even when a large electric current is passed.

[0007]

[Means for Solving the Problems]

 The present invention relates to a battery electrical connector in which two electric wires are electrically connected to one battery electrode. Two battery connectors are arranged so as to sandwich the battery electrode and are directly contacted with each other. The terminal piece is provided with an electric wire crimping portion for crimping each of the two electric wires, and a fastening means for fastening the two terminal pieces to each other while sandwiching the battery electrode.

[0008]

[Action]

 When electrically connecting the electric wire to the battery electrode using the electric connector having the above structure, first, each electric wire is crimped to the terminal piece. Then, the terminal pieces are arranged so as to face each other so as to sandwich the battery electrode, and the terminal pieces are fastened to each other by fastening means to be fixed to the battery electrode. As a result, the two terminal pieces with the electric wires crimped directly contact the battery electrodes, and the electric wires are electrically connected to the battery electrodes.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an electrical connector of an embodiment, and FIG. 2 is a view of the electrical connector as viewed from above. In the figure, 50 and 70 are two terminal pieces that are separately configured. Each of the terminal pieces 50 and 70 is formed by pressing a band plate, and has a crimping portion 60 that is curved in a semi-circular shape so that a cylindrical battery electrode can be sandwiched in a posture in which they are opposed to each other. There is. These crimp portions 60 are portions that directly contact the battery electrodes.

Further, an electric wire crimping portion 62 for crimping the electric wires W1 and W2 is provided at the base end portions of the terminal pieces 50 and 70. Each wire crimping portion 62 is provided on a surface facing outward when the terminal pieces 50, 70 are fixed to the battery electrode. A tightening portion 64 is provided at a position of each wire tightening portion 62 close to the pressing portion 60. The tightening portion 64 is provided with a bolt through hole 66 and a pair of upper and lower engaging pieces 68 protruding toward the outer surface. Then, a square bolt 90 as a fastening means is passed through the bolt through hole 66, and a nut 94 is fastened through a square washer 92, so that the fastening portions 64 of both terminal pieces 50, 70 are fastened together. There is. The engaging piece 68 serves to prevent the square bolt 90 and the square washer 92 from rotating during fastening. Further, 100 is a cushion material sandwiched between the tightening portions 64, 64 of the terminal pieces 50, 70.

A hook-shaped hook portion 54 having an engaging groove 52 into which the tip of the other terminal piece 70 fits is provided at the tip of the one terminal piece 50. When the tip of the other terminal piece 70 is engaged with the hook portion 54, the hook portion 54 functions as a hinge, and the two terminal pieces 50, 70 are connected in a rotatable state. A pair of upper and lower engaging pieces 56 are provided at the tip of the terminal piece 50 to prevent the terminal piece 70 from coming out vertically when the terminal piece 70 is engaged with the hook portion 54. There is.

In order to connect the electric wires W1 and W2 to the battery electrodes by using the electric connector having such a structure, first, the electric wire crimping portion 62 of the terminal pieces 50 and 70 formed in advance as shown in the figure is used. Crim the wires W1 and W2, respectively. Then, the battery electrodes are sandwiched between the two crimping portions 60 with the tips of the two terminal pieces 50, 70 engaged with each other, and in that state, the bolt 90, washer 92, and nut 94 are used to insert the cushion material 100 between them. The tightened portions 64 and 64 are fastened to each other. By tightening in this manner, the crimp portion 60 of each terminal piece 50, 70 is directly crimped to the battery electrode, and the electric wires W1, W2 crimped to the terminal piece 50, 70 and the battery electrode are electrically connected. .

In the case of this embodiment, since the hinge is constructed by simply engaging the tip of the other terminal piece 70 with the hook portion 54 provided at the tip of the one terminal piece 50, it is detachable. Therefore, the work of attaching and detaching the terminal pieces 50 and 70 can be easily performed.

[0015]

[Effect of device]

 As described above, according to the present invention, the two terminal pieces are in direct contact with the battery electrode, and the electric wires are directly crimped to the respective terminal pieces. Moreover, since the electric wire is crimped to the two separate terminal pieces, the crimping work is easy, and the work for fixing the terminal piece to the battery electrode thereafter is also easy.
