The male connector E has a base plate 21 projecting forward from the back portion having the central partition 25 and walls 22 on the both sides of said base plate 21 to form a room R similarly to the female connector D to hold the terminal plate G.
The male connector includes a first male connector E, and a second male connector E On the both lateral faces of the first male connector E, are provided hooks 39 swingeably supported by a supporting portion 40 for engaging with said projection 32 of the first female connector D,, and on the upper and lower surfaces thereof are formed projected portions 43 with notches 41.
The second male connector E is provided with projections 42 for engaging with said notches 41 and stepped projections 44 for contacting with said projected portions 43.
A desired number of said first and second male connectors E,, E are adequately combined by fitting said projection 42 into said notch 41 until the projected portion 43 gets in touch with the stepped projection 44.
The thus combined male connectors E are inserted into the female connectors D previously combined and held by the supporting frame F to enable the terminal plates G respectively in the both connectors D and E to contact with each other.
As apparent from the above description, the female connectors combined and held by the supporting frame serve as a panel connector element to be attached to an intercepting wall and the male connectors combined in one block serve as an attachable connector element.
In FlG. 8, there is shown, in vertical section, the present embodiment employed in a motor-car for connecting the wiring harnesses in the engine room and in the instrument room to each other through the dash panel. The panel connector element comprising female connectors D is inserted in an opening 49 of the dash panel 48 from the engine room. The supporting frame F with its flange 38 covered with a grummet 45 is fitted to the dash panel 48 and secured by bolts 46 and nuts 47 to perfectly separate the instrument room from the engine room.
Then the male connectors connected to the wiring harness in the instrument room and united in one block are inserted into the female connectors to give an electrical connection.
As described above, the female and the male connectors can be adequately combined according to the number of wires required thereby to permit division of wiring work and abbreviate the executing time.
Further according to the present invention, since the connectors are put to use by combining a desired number of the same, a diversed covercan be employed for each block for water proof.
In the both embodiment according to the present invention, the terminal plates of the same structure can be advantageously employed for both the female and the male portions and connectors, thereby to facilitate and simplify a manufacturing process and a quality control.
Since the panel connector element is securely fixed to the intercepting wall such as a dash panel of a motorcar by means of the described fixing members, thereby effectively shutting off poisonous gases, noises etc.
