[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint connector used for various and complicated electric circuits such as a harness circuit of an automobile.

[0002]

2. Description of the Related Art Conventionally, a joint connector can connect an electric wire by branching from a small number of buses to a large number of small wires.
In addition, it has excellent advantages such as connecting a large number of electric wires at once with one touch. For example, a bus bar having a plurality of connection ends formed from a conductive metal plate is inserted into a reception terminal holder in which another number of reception terminals attached to the end of the electric wire are arranged,
2. Description of the Related Art There is known a joint connector in which arbitrary receiving terminals are short-circuited to perform connection. Such a joint connector can be branched and connected to a large number of wiring circuits all at once and in an orderly manner, and is therefore widely used in automobile harness circuits and the like.

[0003]

However, the conventional joint connector described above has a problem that the number of steps is increased and workability is poor because the bus bar is fitted into a holder molded with an insulating synthetic resin. doing.

An object of the present invention is to solve the above-mentioned problems and to provide a joint connector in which busbars can be easily combined or replaced.

[0005]

A joint connector according to the present invention for achieving the above object is made of a synthetic resin containing a bus bar formed by punching a conductive metal plate for connecting between connection terminals. A housing having a busbar accommodating portion for accommodating the busbar in the housing and an openable / closable cover for covering the busbar accommodating portion, opening the cover and inserting the busbar into the busbar accommodating portion; A joint connector for closing the bus bar by closing a cover, wherein a rear end of the bus bar contacts an inner wall surface of the bus bar storage portion, and the cover is located on a side portion of the stored bus bar. And

[0006]

In the joint connector having the above-described structure, the connection terminal is accommodated in the housing, the cover is opened, the bus bar is accommodated in the bus bar accommodating portion, the connection between the connection terminals is established, and the bus bar accommodated by closing the cover is accommodated. Fix it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail based on an embodiment relating to the illustrated flat cable joint connector.

FIG. 1 is a perspective view of the housing of the embodiment with the cover opened when viewed from the rear, FIG. 2 is a perspective view of the housing viewed from the front, and FIG. 3 is a longitudinal sectional view thereof. On the rear side of the housing 1 made of a synthetic resin material or the like, busbar storage portions 2 and 3 and cover portions 4 and 5 are formed integrally with the housing 1 on the upper and lower sides thereof, and the cover portions 4 and 5 are hinged portions 6 and 7. It can be opened and closed freely through. An opening 8 is provided in front of the housing 1 for accommodating a mating housing (not shown) containing a receiving terminal to which a flat cable is connected, and a guide groove 8a for guiding the mating housing is provided in an inner peripheral portion thereof. When,
A locking projection 8b for locking after introduction is provided.

In order to accommodate a plurality of bus bars 9 formed by punching a conductive metal plate as shown in FIG. 4, the bus bar accommodating portion 2 communicates with a plurality of vertical grooves 10 and communicates with the vertical grooves 10. One horizontal groove 11 orthogonal to the vertical groove 10 is provided, and the bus bar 9 is configured to abut the inner wall surface of the bus bar storage unit 2. The bus bar 9 has a plurality of connection ends 9a.
These connecting ends 9a are bridged by a bridging portion 9b, and a locking portion 9c is bent at the bridging portion 9b. The width of the vertical groove 10 of the busbar storage portion 2 is set to a size that accommodates the connection end 9a, and the size of the horizontal groove 11 is set to the size of the busbar 9.
Of the bridge portion 9b. Also,
A groove 12 is formed behind the horizontal groove 11 so as to be offset from the vertical groove 10 so that the state of the bus bar 9 accommodated therein can be checked. The cover 4 is provided with a pressing portion 13 that fits into the vertical groove 10 to fix the bus bar 9, and the rear end of the pressing portion 13 is a step 13 a.

On the other hand, the busbar storage section 3 has a symmetrical shape with the busbar storage section 2, and the cover section 5 has a projection 5a at its tip.
Are formed symmetrically to the cover part 4 except that the cover part 4 is provided. In addition, the cover part 4 is the busbar storage part
And the cover part 5 covers the busbar storage part 3,
These cover parts 4 and 5 are locked with the bus bar storage parts 2 and 3 by a locking mechanism 14, respectively.
5 does not open.

FIG. 6 is a sectional view taken along the line AA of FIG. 3, and shows a state in which bus bars 9, 9'9 "having different numbers of connection ends 9a are housed in the bus bar housing 2.
9 'and 9 "have two connection ends 9a, three connection ends 9a and four connection ends 9a, respectively, and are individually formed from a conductive metal plate. Bus bars 9, 9 ', 9 "are appropriately selected according to the circuit configuration, and the connection ends 9a of the bus bars 9, 9', 9" are aligned obliquely upward with the longitudinal grooves 10 with the covers 4, 5 opened. Insert from
A circuit can be formed by housing the bridging portions 9b in the lateral grooves 11. At this time, the locking portion 9c at the rear end of each bus bar comes into contact with the inner wall surface of the bus bar storage portions 2, 3. Reference numeral 15 denotes a locking portion 9 of the bus bar 9, 9 ', 9 ".
c is a locking groove for retaining to be fitted. When the cover 4 is closed after the busbars 9, 9 ', 9 "are housed in the busbar housing 2, the pressing portions 13 are fitted into the vertical grooves 10, and the busbars 9, 9', 9" are fixed.

In the embodiment, even when the covers 4 and 5 are closed, the respective bridge portions 9 are formed from the rear through the grooves 12.
b can be visually recognized, and it can be confirmed even after assembling whether the circuit configuration is properly performed.
Further, when it is discovered that the circuit configuration is inappropriate or when the circuit configuration is changed, the bus bars 9 can be easily added or replaced by opening the covers 4 and 5.

[0013]

As described above, in the joint connector according to the present invention, since the busbar accommodating portion for accommodating the busbar and the cover for fixing the busbar are integrally formed in the housing, the cover is opened and the busbar is easily inserted. The busbar can be fixed simply by closing the cover. In addition, since the rear end of the bus bar abuts against the wall surface of the housing, the bus bar is stably fixed even when a fitting force is applied to the bus bar from the mating terminal.
Further, the bus bar can be formed in a small size because it can have a simple shape, and the joint connector can also be downsized. In addition, the bus bar can be replaced by opening the cover, and the circuit structure can be easily changed.
