2. Description of the Related Art Conventionally, among wire harnesses for electrically connecting electrical devices, for example, wires connected to the ground and wires using a common electrical signal are connected to the same terminal of the electrical device. Is unsuitable, so that only one electric wire is connected to the terminal of the electric device by conducting the electric current on the way.

As shown in FIG. 7, for example, a bus bar connector 3 for accommodating a so-called bus bar 1 in a housing 2 having a common rear end side of a plurality of male terminals 1a to 1c is provided for the conduction between the electric wires. While preparing, as shown in FIG. 8, each of the electric wires C which need to be inserted (inserted) with the male terminals 1a to 1c of the bus bar 1 and to conduct the electrically connectable female terminals 5a to 5c. To connect the connectors 3 and 7 by fitting the housings 2 and 6 to connect the female terminals 5a to 5c to the male terminals 1a to 1c of the bus bar 1. The connection between the electric wires C is established by connection.

[0004]

However, in the case of such conventional conduction between electric wires, the bus bar connector 3 must be prepared as a separate component in addition to the terminal connector 7, and the production work is required. However, there is a problem that the bus bar connector 3 causes the overall size to be increased.

[0005] The combination of the electric wires C to be conducted does not always have the same pattern. For example, FIG.
As shown in (e), the bus bar 1 and the housing 2 must be prepared for each combination pattern, and the bus bar connector 3 may be color-coded in order to use it properly. For this reason, there has been a problem that the number of parts increases, which hinders cost reduction.

Accordingly, an object of the present invention is to provide a connector capable of reducing man-hours, reducing the number of parts, and saving space by realizing conduction between electric wires without using a bus bar. I do.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, a plurality of first terminals connected to an electric wire attached to an electric device are housed in a housing and connected to other electric wires. A second terminal connected to the first terminal in the housing, thereby electrically connecting the electric wires connected to the first and second terminals.
A terminal is electrically connected to another first terminal adjacent to the first terminal.

According to the first aspect of the present invention, the adjacent first terminals are electrically connected, and the second terminals connected to the first terminals are electrically connected. Therefore, these first,
Electrical connection can be established between the electric wires connected to the second terminals without using special parts such as bus bars. Claim 2
The invention described in (1) is in addition to the configuration of the invention described in claim 1,
The first terminal accommodates the second terminal, or the second terminal

A conductive piece having an elastic force for contacting the terminal and ensuring conduction with the other first terminal, wherein at least one or two or more conductive pieces are provided on the connection body. It is.

According to the second aspect of the present invention, between the first terminals, another conductive piece provided on the connection body for accommodating the second terminal and extending in a direction away from the side surface is adjacent to the other first terminal. By contacting the connection body of the terminal or the conductive piece, conduction between the terminals is ensured. At the time of this contact, the conductive piece has an elastic force, and the contact state is maintained by the elastic force. Therefore, even if each of the first terminals is a separate component, contact failure between the terminals does not occur.

According to a third aspect of the present invention, in addition to the configuration of the second aspect, the housing has a partition wall defining a cavity for accommodating the first terminal individually. Is characterized in that a window is formed so that the conductive piece of the connection body can be opened so as to be able to contact the adjacent other first terminal. According to the third aspect of the present invention, the first terminals are individually housed in the cavities defined by the partition walls of the housing, and the other first terminals are located adjacent to the elastic pieces located in the windows opened in the partition walls. Can contact terminals. Therefore, it is possible to manufacture a connector in which the first terminals are electrically connected only by storing the first terminals in the cavity of the housing, that is, by a normal assembling operation. Can be connected to each other to achieve continuity between wires of another connector.

Here, a plurality of types of first terminals having different numbers and positions of the elastic pieces may be prepared, and the first terminals of different types may be combined and housed in the housing.
In this case, it is possible to freely manufacture a connector according to a pattern for conducting the electric wire. Further, for example, when the side surface of the connection body is a square, the elastic pieces
A window may be formed on the partition wall of the housing in accordance with the pattern for conducting the electric wires. In this case, only the first terminal is housed in the cavity, and the window corresponding to the pattern is formed. A connector can be made.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 4 show a first embodiment of a conductive connector according to the present invention.
It is a figure showing an embodiment. Referring to FIG.
Reference numeral 10 denotes a housing 31 in which a plurality of female terminals (first terminals) 11 are housed in a housing 31. The female terminal 11 is entirely made of a conductive metal.
Is defined by a partition wall 33 having an insulating property.

As shown in FIG. 2, the female terminal 11
12 is plastically deformed so that the core wire c of the electric wire C is crimped and joined. The terminal body (connection main body) 13 is formed in a box shape and a male terminal (not shown)
Terminal) can be inserted and electrically connected.
On two orthogonal side surfaces of the terminal body 13, there are provided elastic pieces 14 having an elastic force which are curved in a direction away from the side surfaces and formed in a convex shape. It is formed to be flat. In addition, this elastic piece
14 may be made by cutting out from the terminal body 13 or may be provided by fixing another metal material.

As shown in FIG. 3, the housing 31 has an insertion opening 34 for inserting and receiving the female terminal 11 to which the electric wire C is connected in the cavity 32, and a partition defining the cavity 32. The window 33 is formed at the position corresponding to the elastic piece 14 of the stored female terminal 11 so that the elastic piece 14 can open into the adjacent cavity 32.

As shown in FIG. 4, the conductive connector 10 is structured such that the female terminals 11 are housed in the cavities 32 of the housing 31 for each of the combination patterns A and B of the electric wires C to be conductive. During this assembly, the elastic piece 14 of the female terminal 11 is housed in the cavity 32 while being elastically deformed by the edge of the insertion port 34, and then the elastic piece 14
Is elastically restored, and presses against the side surface of the terminal body 13 of another female terminal 11 adjacent to the window 35 of the partition wall 33 and adjacent thereto. Therefore, the female terminal 11 can make contact with the adjacent female terminal 11 without causing a contact failure due to the elastic force of the elastic piece 14 to secure conduction, and at this time, the elastic piece 14 of the female terminal 11 Since it is formed in a plane, it can contact the side surface of the terminal body 13 of the adjacent female terminal 11 with a large area, and the electric capacity does not decrease.

Further, since the elastic piece 14 elastically returns into the window 35 and engages with the partition wall 33 of the housing 31, it also functions as a means for preventing the female terminal 11 from coming off. When the male terminal that is inserted into and electrically connected to the female terminal 11 is assembled in a connector (not shown) that houses the housing 31, the female terminal 11 and the male terminal are connected by a normal connector connection. Of the electric wire C can be taken.

As described above, in the present embodiment, the electric wire C
The female terminal 11 is freely (freely) accommodated in the cavity 32 of the housing 31 in accordance with the pattern of the conduction of the elastic piece 14 so that the elastic piece 14 faces the window 35 of the partition wall 33 and the adjacent female terminal
11 can be contacted. Therefore, conduction between the female terminals 11 can be easily secured, and the female terminals 11
The male terminals connected to the terminals can also be electrically common. Therefore, when assembling a normal connector, the conductive connector 10 is employed to adopt the electric wire C which needs to be conductive.
By using the female terminal 11 in a pattern corresponding to the above, it is possible to easily secure the conduction of only the necessary electric wire C without using a special part such as a bus bar for conduction. The electric wire C that is electrically connected to the female terminal 11 to be electrically common may be connected to the male terminal on the connector side to be fitted to the conductive connector 10. As a result, the number of steps, the number of parts, and the space can be reduced.

An elastic piece 14 for establishing conduction between the female terminals 11 is provided.
Since the flattened top portion is elastically restored by the elastic force and pressed against the adjacent terminal body 13, it functions not only as a stopper, but also as a contact failure, and ensures a sufficient electric capacity. Can be. Next, FIG. 5 and FIG. 6 are views showing a second embodiment of the conductive connector according to the present invention. Note that the present embodiment is formed substantially in the same manner as the above-described embodiment, and therefore, the same components will be described with the same reference numerals.

In both figures, the conductive connector 20 has elastic pieces 14 on only one side of the terminal body 13 in addition to the plurality of female terminals 11.
Female terminal 21 provided with a cavity 32 of the housing 31
It is stored and assembled inside. In this embodiment, the elastic connector 14 is a conductive connector using the female terminal 21 having only one side.
Since 20 is assembled, the combination patterns F and G in FIG.
And the other female terminal 11 adjacent to the female terminal 21
The housing 32 can be housed in the cavity 32 without being electrically connected to the housing 21, so that the cavity 32 of the housing 31 can be used effectively.

In the above-described embodiment, a square terminal body is used.
Although an example in which one or two elastic pieces 14 are provided on the 13 side faces has been described, the present invention is not limited to this, and the elastic pieces 14 may be provided on three or four side faces. Alternatively, conduction may be achieved. Further, the position of the elastic piece 14 is not limited to the above-described embodiment, and may be provided on the upper, lower, left and right side surfaces of the terminal body 13 or may be arbitrarily designed as necessary so that the number of parts does not become too large. .

Further, as another aspect of the above-described embodiment, a housing at a position corresponding to a pattern for conducting the electric wire C is provided.
The window 35 may be opened only in the partition wall 33 of the 31,
As a result, the types of female terminals used can be reduced, and the cavity 32 can be used effectively.
In the above-described embodiment, an example in which the elastic pieces 14 are provided on the side surfaces of the square terminal body 13 will be described.
Needless to say, it is not limited to corners. For example,
The same can be applied to a cylindrical shape. Further, in the above-described embodiment, conduction is established on the female terminal 11 side, but it goes without saying that conduction may be established on the male terminal side.

In the above-described embodiment, the housing 32 in which the cavity 32 for accommodating the female terminal 11 is defined by the partition wall 33.
Although 31 is used, the female terminal 11 may be directly accommodated in a housing without a partition wall, or a connector may be manufactured using only the female terminal. However, since the connector is not stable, the connector is preferably configured as in the above embodiment. It is.

[0023]

According to the first aspect of the present invention, since the first terminal can be electrically connected, an electric wire is connected to the first and second terminals without using a special part such as a bus bar. Only the continuity between the wires can be obtained. Therefore, it is not necessary to manufacture a connector or the like for accommodating the bus bar, so that the number of steps, the number of parts, and the space can be reduced.

According to the second aspect of the present invention, since the conductive piece having the elastic force of the first terminal comes into contact with another adjacent first terminal to establish conduction between the terminals, contact failure may occur. Absent. Therefore, conduction between the terminals can be ensured with high reliability. According to the third aspect of the present invention, the first terminal is housed in the cavity defined by the partition wall of the housing, and the elastic piece faces the adjacent cavity through the window of the partition wall to form another first terminal. Because it contacts one terminal,
Just by storing the first terminal in the cavity as in a normal assembling operation, it is possible to manufacture a connector in which the first terminal is electrically connected, and easily store the second terminal in the connector fitted to the first terminal. Conduction between electric wires can be taken. Therefore, the work can be easily performed, and the electric wires can be electrically connected in a connector to which a normal wire harness is connected, instead of the connector for connecting the electric wires.
