Abstract
ABSTRACT
An electrical connector comprises an electrical terminal having a contact end and a crimping ferrule for connection to an electrical conductor, the crimping ferrule being received in a metal sleeve which extends beyond the end of the crimping ferrule in the direction away from the contact end of the terminal, the metal sleeve in turn being received in an outer sleeve of electrically insulating material. The metal sleeve is a seamless member having a relatively thick wall over the portion overlying the crimping ferrule, and a relatively thin wall over the portion extending beyond the end of the crimping ferrule. The different thicknesses of the two portions of the metal sleeve ensure reliable crimping of the connector to an insulated conductor at these two positions.

Description
Thjs i.nvention relates to an electrical connector.
~ ccordinc~ to this invention an electrical connector comprises an electrical terminal havlng a con~act end and a crimping ferrule for connection to an electrical conductor, the crimping ferru~.e being received in a metal sle2ve ~hich extends beyond the end of the cr.imping ferrule in the direction away from the contact end of the terminal, the metal sleeve belng a seamless member llaving a relaiively thick wall over the portion overlying the crimping ferrule, and a relatively thin wall over the portion extending beyond t.he end of the crimping ferrule, the metal sleeve in turn being received in an outer sleeve of el2ctrically insulating material.
An electrical connector according to this invention will now be described by way of example with reference to the drawings, in which:-Figure 1 is a side elevational view, partly in cross-section, of a metal sleeve of the connector;
Figure 2 is a sectional plan view of the sleeve of Figure 1 recaived in an outer lnsulating sleeve of the conn~c~or; and Figure 3 is a plan view of the complete connector.

sleev~ can be forrn~.a by conventional metal working techniques.
Be~ween the portions 2 and 3 is an intermediate portion 4 providing a funnel entry 5 from the portion
3 into the portion 2. The intermediate portion 4 also provides a shoulder 6 facing into the portion 2.
The free end 7 of the portion 3 is flared out~ardly to provide a funnel entry there-to.
Referriny now to Figure 2, this shows the metal sleev2 1 received in an outer sleeve 8 of electrically insulating plastics material, which outer sleeve 8 extends beyond the ree end 7 of the poxtion 3 of the sleeve l.
Figure 3 shows the complete connector which includes an electrical terminal 9 having a receptacle contact end.10 for mating ~ith a flat tab (not shown) and a crimping ferrule 11 of known form for connection to an electrical conductor, the crimping ferruls 11 being received in the portion 2 of the metal sle~ve 1 with its insertion limited by the shoulder 6 therein.
For use of the connector, the insulation 12 is stripped rom a portion at the end of an insulated elec~r:ical~ conductor 13, and the end portion is then .inserted into the free end of the outer sleeve 8 ~ith the end o the conductor 13 ~eing guided into the crimping ferrule 11 by ~he funnel entry 5 .

of the metal sl2eve 1, which funnel entry 5 also serves to limit insertion of the conductor by engagelnent of the insulation 12 on the conductor with the funnel entry 5. The crimping ferrule 11 is then crimped down onto ~he conductor 13 through the outer sleeve 8 and the portion 2 of the metal sleeve 1, and the portion 3 of the metal sleeve 1 can be crimped down onto th~ insulation 12 of the conductor throu~h the outer sleeve 8, in known manner.
lo The relatively thick wall of the portion 2 of the metal sleeve 1 ensures reliable crimping of the connector 1 onto the conductor 13 even when the materiàl from ~7hich the terminal 9 is made is relatively thin as may be necessary to ensure the necessary spring propsrties for the receptacle end 10 thereof, while the relatively thin wall of the portion 3 of the metal sleeve 1 allo~s for easy crimping of this portion onto the insulation 12 of the conductor.
Further, the absence of a seam in the metal sleeve 1 en~sur s that the metal sleeve 1 will not relax after crimping as could occur if the metal sleeve 1 ; had a longitudinally extending open seam as found in some known connectors.
