[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chain-type electrical connector incorporated in a fuse box or the like mounted on an automobile.

[0002]

2. Description of the Prior Art As shown in FIG.
1, 21 'was protrudingly provided. Such a chain-like electric connector 20 is used for intensively interconnecting a wide variety of electric wirings, and is incorporated in a fuse box or the like of an automobile.

[0003]

However, in the chain-like electric connector 20 constructed as described above, when the electric wire is crimped and connected to the electric wire crimping portion 22 formed by bending the electric connector 21, the electric connector 21 Extend in the axial direction (the direction of the arrow), causing a difference in the length dimension from the electric connector 21 ′ that does not crimp the electric wire to the electric wire crimping portion 22 ′, which causes a problem in mounting in the housing. For this reason,
An operation is required in which an electric wire crimping portion 22 ′ formed by bending the electric connector 21 ′ that does not crimp the electric wire is punched without crimping the electric wire to extend the electric connector 21 ′ in the axial direction. Further, since the plurality of electrical connectors 21 and 21 ′ are continuously and integrally connected to the strips 23 on the bottom surfaces of the wire crimping portions 22 and 22 ′ formed by being bent substantially in a U shape, However, there is a problem that the electric strength cannot be increased due to a low mechanical strength and a high electric resistance.

As means for solving the above problem, as shown in FIG. 5, an electric contact portion 31 formed by bending an electric connector 30 and an electric wire crimping portion 32 are continuously and integrally connected by a strip 33, and A chain-shaped electric connector is constructed in such a manner that the axial elongation when the electric wire is crimped and connected to the crimping portion 32 does not affect the electric contact portion 31 and is limited only to the electric wire crimping portion 32. It is disclosed in Japanese Patent Application Publication No. By configuring the chain-like electrical connector as described above, there is an advantage that the mechanical strength of the chain-like electrical connector can be improved and the electric capacity can be increased. On the other hand, when the electric contact portion 31 and the wire crimping portion 32 are continuously and integrally connected by the strip 33, the electric connector 30 becomes longer in the longitudinal direction, and the overall shape of the chain-like electric connector becomes large. There is a point.

The present invention has been made in view of the above problems, and has as its object to provide a chain-shaped electrical connector which is small and has excellent electrical characteristics.

[0006]

SUMMARY OF THE INVENTION In order to solve the problems of the prior art, the present invention solves the above-mentioned problems by connecting the electric contact portions formed by bending to a plurality of electric connectors continuously and integrally with a strip. It is what constituted.

[0007]

The chain-like electrical connector intensively interconnects various electric wirings. The opposite terminal is inserted and connected to the electric contact portion bent and formed on each electric connector, and the electric wire is crimped and connected to the wire crimping portion bent and formed on a predetermined electric connector.

[0008] Thus, by forming a chain-like electrical connector by connecting the electrical contact portions formed by bending the plurality of electrical connectors continuously and integrally with a strip, the electrical contacts are bent into a predetermined electrical connector. When the wire is crimped to the wire crimping part, the axial extension of the electrical connector does not affect the electrical contact part, but only the wire crimping part, so there is no problem with mounting in the housing. Therefore, it is not necessary to blank the wire crimping portion formed by bending another electric connector which does not crimp the wire. In addition, by connecting the electrical contact portions formed by bending to the plurality of electrical connectors continuously and integrally with a strip, the electrical connector is reduced in size in the longitudinal direction, the electrical resistance of the electrical connector is reduced, and
Heat generated by contact resistance when the other terminal is connected can be efficiently released to the strip. Furthermore, by reducing the size of the electrical connector in the longitudinal direction, the overall shape of the chain-like electrical connector is also reduced. Furthermore, the pitch between the electrical connectors can be easily adjusted by bending the strip into a concave shape or a V shape.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG.
In the drawing, reference numeral 1 denotes a chain-like electric connector formed by bending a conductive metal plate having a spring property, and the chain-like electric connector 1 is connected to an electric contact portion 3 in a longitudinal direction as shown in FIG. A plurality of electric connectors 2, which are formed by successively bending the wire crimping portion 5, are continuously and integrally connected with the electric contact portions 3, 3 formed by bending the electric connectors 2, 2 by a strip 6. It is formed.

In order to form the chain-like electrical connector 1 by bending a conductive metal plate having spring properties, as shown in FIG. The folded tongue pieces 4a, 4a are folded inward from the position shown by the dotted line a to form the contacts 4, 4 shown in FIG. 1, and the plate surfaces 3a, 3a continuous with the contacts 4, 4 are shown by the dotted line b. The electric contact 3 shown in FIG. 1 is formed by rising upward from the position, and the strip 6 is bent horizontally from the position shown by the dotted line c to connect the electric contacts 3 continuously with each other. Sleeves 5a, 5a stamped and formed at the base end of conductive metal plate A
Is bent into a substantially U shape from the bottom surface to form the wire crimping portion 5.

The shape of the electrical contact portion 3 formed by bending the electrical connector 2 is not limited to the above-described embodiment, but can be changed as needed.

As described above, the electrical contacts 3 formed by bending the plurality of electrical connectors 2 and 2 are continuously and integrally connected by the strip 6 to form the chain-like electrical connectors 1. When the electric wire is crimped and connected to the wire crimping portion 5 formed by bending the predetermined electric connector 2, the axial extension of the electric connector 2 does not affect the electric contact portion 3.
Therefore, there is no problem in installation in a housing (not shown), and therefore, it is not necessary to punch the electric wire crimping portion 5 bent and formed on another electric connector 2 which does not crimp and connect the electric wire.

Further, since the electrical contacts 3, 3 formed by bending the plurality of electrical connectors 2, 2 are continuously and integrally connected to each other by the strip 6, the electrical connector 2 is downsized in its longitudinal direction. The electrical resistance of the electrical connector 2 is reduced,
In addition, since the heat generated by the contact resistance when the counterpart terminal is connected can be efficiently released to the strip 6, the heat generation of the chain-shaped electric connector 1 is extremely effectively suppressed.

Furthermore, by reducing the size of the electrical connector 2 in the longitudinal direction, the overall shape of the chain-like electrical connector 1 is also reduced, and a housing for mounting the chain-like electrical connector 1 and a chain-like electrical connector are provided. It is possible to reduce the size and weight of a fuse box or the like incorporating the housing to which the connector 1 is mounted.

Further, as shown in FIG. 3, the pitch P between the electric connectors 2 and 2 can be adjusted very easily by bending the strip 6 into a concave shape or a V shape.

[0016]

According to the present invention, as described above, it is possible to improve the electrical characteristics while reducing the size of the chain-like electrical connector 1, and to form a crimped wire on the predetermined electrical connector 2. The extension in the axial direction when the wire is crimped and connected to the portion 5 does not affect the electric contact portion 3 but only the wire crimp portion 5. Therefore, the wire crimp portion 5 formed on the other electric connector 2 is emptied. There are excellent advantages, such as no need for a hitting operation.
