DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling type connector in which a plurality of connector housings having connection terminals inserted thereinto by an automatic machine are integrally combined to form a connector having connection terminals of multiple circuits. .

[0002]

2. Description of the Related Art A plurality of divided connector housings in each of which a housing for accommodating connection terminals is formed in a horizontal row are provided.
As these split connector housings, there are known assembling connectors in which a connector having a multi-circuit is formed by connecting the split connector housings in upper and lower tiers after connecting terminals are inserted by an automatic machine.

[0003] As a conventional example of this assembly type connector, there is a structure as shown in FIG. 1, wherein 1 is a first split connector housing, 2 is a second split connector housing, and both of them are split. Connector housings 1 and 2
First, the connection terminals are formed in such a manner that the connection terminals are inserted into the respective split connector housings by an automatic machine and then assembled integrally.

A plurality of terminal accommodating chambers 3 are formed in each of the split connector housings 1 and 2 in a horizontal row, and a connection terminal formed by connecting an electric wire 4 in each terminal accommodating chamber 3 in advance. 5 can be inserted by an automatic machine.

At the four corners of the lower surface of the first split connector housing 1, locking claws 6 are projected, and at the four corners of the upper surface of the second split connector housing 2, the above-mentioned locking claws 6 are provided. A locking hole 7 to be locked is formed.

The work of inserting the connection terminal 5 to which the electric wire 4 is connected in advance into each terminal accommodating chamber 3 in each of the split connector housings 1 and 2 is performed by holding the electric wire 4 by an automatic machine. The connection terminal 5 is connected to the terminal receiving chamber 3
, And the connection terminal is pushed into the terminal accommodating chamber while holding the wire, thereby completing the insertion of the connection terminal. Then, the first split connector housing 1 and the second split connector housing 2 after the terminal insertion into each terminal accommodating chamber is completed, by the locking action of the locking claw 6 and the locking hole 7, When they are connected, a target multi-pole connector is formed.

[0007]

However, when inserting the connection terminal 5 into each of the terminal accommodating chambers 3, the electric wire 4 is clamped. Buckling is likely to occur in the electric wire, which makes it difficult to completely accommodate (reliably accommodate) the connection terminal,
At times, there are problems such as poor insertion or inability of terminal insertion by an automatic machine.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an upper portion of each terminal accommodating chamber formed in a connector housing body and a shelf frame into which connection terminals are to be inserted is opened. The structure is such that each connection terminal can be accommodated in the terminal accommodation room from the upper opening of the terminal accommodation room, and each connection terminal is not affected by the thickness of the electric wire. Is to provide an assembling type connector that can be easily and reliably set (interior) in a connector housing main body and a shelf frame using an automatic machine.

The configuration of the present embodiment has been described above. Next, the operation will be described.
A connection terminal 28 carried by an automatic machine (not shown) is fitted into the terminal accommodating grooves 13 and 23 arranged on the first and shelf frames 22 from directly above the terminal accommodating grooves 13 and 23. I do. This fitting operation can be performed by a simple fitting operation by an automatic machine.

The shelf frame 22 fitted with the connection terminals 28 is placed on the connector housing main body 11 after the connection terminals 28 are fitted and set, and the latch provided on the shelf frame 22 is provided. The claw 27 is locked in the locking hole 21 provided in the connector housing main body 11, and the connector housing main body 11 and the shelf frame 22 are connected. Next, the upper lid 18 provided on the connector housing body 11 is put on the shelf frame 22, and the locking claws 19 are locked in the locking holes 26 provided in the shelf frame 22. Type male connector is completed.

As described above, in this embodiment, the connector housing body 11 and the shelf frame 22 are provided with the terminal accommodating grooves 13 and 23 whose upper surfaces are opened. Since it is configured to fit in the receiving grooves 13 and 23, the connecting terminal fitting operation by the automatic machine is smooth and easy, the number of assembly steps can be reduced, and the productivity is improved.

Embodiment 2 This embodiment is shown in FIG. 3. The connector housing main body 11 'shown in this embodiment is a mating connector fitting portion into which the male connector shown in Embodiment 1 is fitted. 30
It is provided integrally with the bottom wall portion 12 and the partition wall 14 that form the same plurality of terminal accommodating grooves 13 as in the first embodiment. In the following description, since the structure is substantially the same as the structure shown in the first embodiment, the same reference numerals as those in the first embodiment are attached and the outline of the structure is described.

[0021]

As described above, the present invention provides a connector housing main body 11 or 11 'in which a plurality of terminal receiving grooves into which a plurality of connection terminals are fitted are formed, and an opening of the terminal receiving groove of the connector housing main body. A shelf frame 22 on which a plurality of terminal receiving grooves are formed and arranged to fit a plurality of connection terminals, and the shelf frame is overlaid on the connector housing body, and then placed on the shelf frame. Top lid 1 to be attached
8 is an assembling connector provided in the connector housing main body so as to be openable and closable. According to this, each terminal accommodating groove provided in the connector housing main body and the shelf frame is open at the upper side. It is possible to automate the work of fitting the connection terminal into each terminal accommodating groove and the work of connecting the connector housing body and the shelf frame, and it is also possible to simultaneously fit each row, thereby assembling a multi-pole connector. The effect of improving productivity and economic efficiency accompanying the reduction of man-hours can be obtained. Also, since the completed connectors are not overlapped individually as in the conventional example, it is not necessary to combine the mating connector as a separate connector for each row. Therefore, the size in the overlapping direction (upward in the embodiment) can be minimized, so that a compact and cheap connector can be provided.
