Joint connector

The present invention relates to a connector, and more particularly to a connector having a joint terminal for electrically connecting between terminals provided inside the connector.

In general, the connector is composed of a connector housing and a terminal, and is widely used in power circuits such as washing machines, refrigerators, or automobiles. The use of the connector in these electrical and electronic devices can assemble a plurality of parts separately and then insert them into the final product, which has the advantage of greatly simplifying maintenance work as well as device manufacturing.

Such a connector is electrically connected between terminals provided between the two by connecting the mating connector. In this case, the connector may be provided with a plurality of terminals. In addition, the mating connector may be provided with a busbar type terminal for electrically connecting the plurality of terminals to each other. Such a connector is generally referred to as a joint connector.

By doing so, it is electrically connected between the counter terminals. Each of the terminal parts 6a to 6t is provided with a coupling part 8 so as to be press-fitted into the housing of the joint connector 5 so that the joint terminal 6 is not arbitrarily removed from the housing.

On the other hand, the bus bar terminal 6 does not need to be electrically connected to all of the joint connector (5). For example, a bus bar terminal 6 electrically connected between a total of five terminal parts 6a to 6e is provided, and a bus bar terminal electrically connected to a total of five terminal parts 6f to 6j is separately provided. 6) is provided and the remaining terminal parts (6k ~ 6t) may be separately connected to each of the joint connector (5).

However, the prior art as described above has the following problems.

The bus bar terminal 6 used for the joint connector 5 is made so that the respective terminal portions 6a to 6t are arranged in a line, as shown in FIG. Such a bus bar terminal 6 is made by successive machining sequentially in a progressive mold. Therefore, in order to make the bus bar terminal 6 in which the terminal parts 6a to 6t are lined up in this way, a relatively large process time is required. For example, if it takes one second to make one terminal part, the bus bar terminal 6 shown in Fig. 2 takes 20 seconds.

In addition, the bus bar terminal 6 of the prior art should be such that each terminal portion 6a to 6t has a coupling portion 8 separately so as not to be detached from the housing of the joint connector 5 arbitrarily. Accordingly, there is a problem in that the bus bar terminal 6 is made relatively, which costs a lot of materials.

Accordingly, an object of the present invention is to solve the conventional problems as described above, and to more quickly manufacture the bus bar terminal constituting the joint connector.

As the seating slot is formed to the insertion hole, a coupling bar is formed in the housing. An end of the coupling bar is provided with an elastic piece that is elastically deformed to enter and exit the bus bar terminal into and out of the seating space.

The elastic piece is made elastically deformable by forming an elastic groove at the tip of the coupling bar, and the locking jaw protrudes from the inner surface of the elastic piece to face the bottom surface of the seating space.

The locking jaw is formed in a plane in which the inner side facing the inside of the seating space is upright on the surface of the opening piece, so that the connection portion of the bus bar terminal is walked and the outer side facing the outside of the seating space is formed as an inclined surface or curved surface.

The length of the connection part is formed to be equal to the distance between the inside of the seating space and the locking step.

As the seating slot is formed to the insertion hole, a coupling bar is formed in the housing, and a hook bar that is elastically deformable is formed in a through groove passing through the housing in the seating space facing the coupling bar. Secure in the seating space.

A locking boss is formed in the coupling bar to protrude into the seating space, and a hook hole into which the locking boss is inserted is formed at the connection portion of the bus bar terminal.

The seating space is divided into two inside the housing, and each insertion hole is formed at both ends of the housing, and a bus bar terminal made separately is inserted into each seating space.

In the joint connector according to the present invention, the following effects can be obtained.

The seating slots 16 are formed to extend to the insertion hole 14, two of which extend side by side at a predetermined interval. As the seating slot 16 is formed in this way, the coupling bar 18 is formed in the housing 10. The coupling bar 18 partitions the seating space 12 and the outside of the housing 10 into a kind of cantilever shape. The tip of the coupling bar 18 forms part of the insertion hole 14.

The coupling bar 18 is dimensioned so that almost no elastic deformation occurs except for a portion of the opening piece 22 which will be described below, which is formed at the tip portion. This is because the coupling bar 18 must be firmly fixed to the connecting portion 28 of the bus bar terminal 26 installed in the seating space 12. The coupling bar 18 may have resistance to elastic deformation by appropriately designing the thickness thereof.

An elastic groove 20 is formed at the tip of the coupling bar 18, and the thickness of the coupling bar 18 of the portion where the elastic groove 20 is formed is relatively thin, so that an opening piece is provided at the tip of the coupling bar 18. (22) is formed. Since the opening piece 22 is elastically deformable at a portion corresponding to the elastic groove 20, the opening piece 22 can be opened and closed.

A locking jaw 24 is formed to protrude from the opening piece 22 to the seating space 12. The locking jaw 24 is usually in close contact with the bottom surface of the seating space 12, the opening piece 22 is elastically deformed to expand the insertion hole 14, the bottom surface of the seating space 12 To allow the bus bar terminal 26 to enter and exit the seating space 12 from the outside.

The hooking jaw 24 has a portion corresponding to the inner side of the seating space 12 has a plane upright with respect to the surface of the opening piece 22, the connection portion 28 of the bus bar terminal 26 to be described below Is not allowed to walk out of the house. In addition, the portion corresponding to the outside of the seating space 12 in the locking step 24 is an inclined surface or curved surface so that the bus bar terminal 26 can be easily inserted into the seating space 12. As such, when the outside of the locking step 24 is an inclined surface or a curved surface, the opening piece 22 may be elastically deformed without a separate tool.

The bus bar terminal 26 is made of a conductive metal material. The bus bar terminal 26 has a connecting portion 28 extending in the same direction as the extending direction of the housing 10 and seated inside the seating space 12, and in the longitudinal direction of the connecting portion 28. The terminal portion 30 extends symmetrically in both orthogonal directions. The length of the connection portion 28 is equal to the length from the inner side of the seating space 12 to the locking step 24 of the opening piece 22. By doing so, the bus bar terminal 26 does not flow arbitrarily inside the seating space 12.

The terminal portion 30 is bent 90 degrees at a portion extending from the connecting portion 28 so that the front end portions of all the terminal portions 30 extend in the same direction. The bent portion of the terminal portion 30 is in a position adjacent to the seating slot 16 in the seating space 12. A portion of the terminal portion 30 extending to both sides with respect to the connecting portion 28 and extending in parallel in the same direction extends through the seating slot 16 to the outside of the housing 10. The protruding portion of the terminal portion 30 protruding to the outside of the housing 10 is inserted into the mating connector and electrically connected to the terminal inside the mating connector.

On the other hand, Figure 6 shows another embodiment of the present invention. In the embodiment described above, all terminal portions 30 are electrically connected, but in this embodiment, the terminal portions 30 are divided into two groups and electrically connected.

In this embodiment, the seating space 12 of the housing 10 is separated into two, and the insertion hole 14 is formed at both ends of the housing 10, respectively. In this way, the bus bar terminals 26 electrically separated from each other are seated in the separated seating spaces 12. In the illustrated embodiment, one bus bar terminal 26 has six terminal parts 30 and the other bus bar terminal 26 has four terminal parts 30.

Figure 7 shows another embodiment of the present invention. In the present embodiment, for the sake of convenience of description, components similar to those of the embodiment shown in FIG. In this embodiment, the locking boss 124 protrudes into the seating space 112 of the housing 110 without a configuration for coupling the bus bar terminal 126 to the coupling bar 118 of the housing 110. The hanger bar 122 is formed. The hook bar 122 is provided in the through part 120 penetrating the housing 110 to allow elastic deformation. The hook bar 122 is formed to protrude into the mounting boss (124) the seating space (112).

In addition, the bus bar terminal 126 is provided with a plurality of hook holes 128 ′ on which the engaging boss 124 is hooked to the connection portion 128. The bus bar terminal 126 is not separated from the seating space 112 by the locking boss 124 is inserted into the hook hole 128 '.

Hereinafter, the joint connector according to the present invention having the configuration as described above will be used in detail.

The joint connector of the present invention is configured such that a part of the connection portion 28 and the terminal portion 30 of the bus bar terminal 26 is positioned in the seating space 12 of the housing 10. Inserting the bus bar terminal 26 into the seating space 12 is as follows.

One end of the connecting portion 28 of the bus bar terminal 26 made in the form as shown in FIG. 4 is positioned in the insertion hole 14 of the housing 10. When one end of the connecting portion 28 is inserted into the seating space 12 through the insertion hole 14, the opening piece 22 should be elastically deformed.

The elastic deformation of the opening piece 22 may use the connecting portion 28 of the bus bar terminal 26 or a separate tool. When the opening piece 22 is elastically deformed, the locking jaw 24 is spaced apart from the bottom surface of the seating space 12 to open the insertion hole 14. When the insertion hole 14 is opened, the connection portion 28 of the bus bar terminal 26 and the terminal portion 30 extending in both longitudinal directions thereof are inserted into the seating space 12. In this process, the terminal portion 30 is bent at a right angle so that each terminal portion 30 extends in parallel to move along the seating slot 16.

After the connecting portion 28 of the bus bar terminal 26 completely enters the seating space 12 of the housing 10, the force used to elastically deform the opening piece 22 is removed. When the force used to elastically deform the opening piece 22 is removed, the opening piece 22 is returned to its original position, and the locking jaw 24 is in close contact with the bottom surface of the seating space 12. Therefore, the bus bar terminal 26 that enters into the seating space 12 does not come out of the seating space 12 arbitrarily because of the locking jaw 24.

In addition, one end of the bus bar terminal 26 is in close contact with the inside of the seating space 12, and the other end thereof is walked on the plane of the locking jaw 24 so that the bus bar terminal 26 does not arbitrarily flow inside the seating space 12. do.

The joint connector of the present invention assembled as described above is coupled to the mating connector so that the terminal in the mating connector and each terminal portion 30 are electrically connected. As such, the terminals of the counterpart connectors electrically connected to the respective terminal units 30 are all electrically connected to form a circuit.

Of course, in the embodiment shown in Figure 6 the terminals of the mating connector is divided into two groups and electrically connected.

Meanwhile, in order to remove the bus bar terminal 26 from the seating space 12, the opening piece 22 is elastically deformed so that the locking jaw 24 is spaced apart from the bottom surface of the seating space 12. In this process, the connecting portion 28 of the bus bar terminal 26 is separated from the locking jaw 24. When the latching jaw 24 is spaced apart from the bottom surface of the seating space 12, the insertion port 14 is opened so that the bus bar terminal 26 can come out of the seating space 12.

The scope of the present invention is not limited to the embodiments described above, but may be defined by the scope of the claims, and those skilled in the art may make various modifications and alterations within the scope of the claims It is self-evident.
