Abstract
ABSTRACT
TERMINATING DEVICE FOR WIRE:
A terminal for terminating wire comprises a contact portion for electrical connection to a conductor of the wire and a crimping portion for crimping to insulating material on the wire. The crimping portion is formed to have an outwardly bulged barrel-like portion. The bulged portion provides a configuration that has a dimension greater than that of burrs which may be formed during fabrication of the terminal. Thus, in use, for example, where the terminal is to be inserted through a water-seal bushing, damage resulting from sharp burrs may be minimized.

TERMINATING DEVICE FOR WIRE
1 FIELD OF INVENTION:
This device relates to an electrical terminal used to terminate a wire, and in particular to a terminal useful for terminating a wire connected to a water-proof connector.
BACKGROUND OF THE INVENTION~
A terminal according to the prior art is described with reference to Figures 5 to 7.
Figure 5 shows terminal 1' as it is connected by a connecting plate known as a carrier 4'. The terminal actually used is severed from the carrier plate. As shown in Figure 6, insulating material of a wire is crimped by a portion of the terminal and another portion thereof is electrically connected to a conductor having the insulating material removed therefrom to expose the conductor.
In this case, burrs 9' formed when the terminal is severed from the carrier outwardly protrude greater than the outer diameter of that portion of the terminal which crimps the insulating material of the wire, as shownO When the wire thus terminated is to be connected to a water-proof connector, for example, it is necessary to push it through a rubber bushing as shown in Figure 1 which will be described later, and therefore, at that time, the burrs can damage the rubber bushing to thereby reduce the waterproofing effect of the connector. Figure 7 shows a prior art terminal having a receptacle at the tip end thereof.
SUMMARY OF THE INVENTION: ~
The present device has as its object the provision of a terminal having structure which reduces the above-noted deficiencies peculiar to th,e prior-art terminating devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT:
Figure 1 shows a wire terminated by the terminal of the ` present invention as it is used in a water-proof connector. In Figure 1, the reference numeral 10 designates a first housing (of the plug type), the reference numeral 11 denotes a second housing (of the cap type) fitted to the first housing, and the reference numeral 12 designates a locking spring mounted on the top of the first housing. When the two housings 10 and 11 are fitted together, the engagement projection of the second housing 11 is engaged with an engagement hole formed in the spring. The reference numeral 13 denotes a rubber bushing contained in a concavely depressed portion formed in the first housing 10. The rubber bushing 13 is formed with a plurality of through-holes through which are extended wires terminated by the terminal according to the present device.
The terminal 1 of the preferred embodiment has a receptacle 2 provided at the tip end thereof, and is contained in a containing groove provided in the first housing 10. A
ferrule 3 is provided on the end of the receptacle of the terminal, and as shown, it is engaged with a lance 14 provided in the containing groove of the housing 10, thereby holding the terminal 1.
In Figure 1, the reference numeral 15 designates a sealing member, the reference numeral 16 denotes an earth plate, the reference numeral 17 designates a through capacitor, and the reference numeral 18 denotes a printed circuit board.
The reference numeral 19 designates a pin contact, one end portion of which is inter-fitted to the receptacle 2 of the terminal 1 of the present device to thereby make electrical contact therewith. The other end portion of the pin contact 19 2 0 2 1 ~ 2 ~
is electrically connected to a conductive pattern of the printed circuit board.
Figure 2 show~ a terminal 1 of the present device as it is connected to a connecting plate called a carrier 4. The terminal actually used is cut at a location indicated by a dot-and-dash line 20 and severed from the carrier 4, which defines an inwardly directed tab.
Figure 3 shows the essential portions of a wire 5 terminated b~ such the terminal 1. As shown, the terminal of the present device comprises a contact portion 7 electrically connected to an exposed portion of a conductor 6 of the wire 5, and an insulating material crimping portion 8 for crimping insulating material of said wire, said insulating material crimping portion having an outwardly bulged barrel-like portion 8a.
Burrs 9 may be formed when the terminal 1 is severed from the carrier. However, in the present device, as is apparent from Figure 3, the barrel-like portion 8a of the insulating material crimping portion bulges out to a dimension greater than the outer diameter of the burr portion.
Figure 4 shows the tip end portion 2 of the wire 5 . -.
terminated by a terminal of the type having a receptacle, according to the present device.
In Figure 2, a level difference is provided in a region wherein the insulating material crimping portion 8a is connected to the carrier, and this also is effective for preventing burrs from protruding beyond the outer diameter of the insulating material crimping portion 8a. A similar effect may be provided by forming a recess in the region wherein the insulating material crimping portion is connected to the carrier.
In the terminal according to the present device, the barrel-like portion of the insulating material crimping portion bulges out to a dimension greater than the outer diameter of the burr portion formed when the terminal is severed from the carrier. Therefore, when a wire terminated by such the terminal is connected, for example, to a water-proof connector, the rubber ,, .: . . . ~: ~ - . ~
