Description

ASSEMBLY OF A WIRE AND AN ELECTRICAL CONTACT AND METHOD OF
MANUFACTURE
FIELD OF THE INVENTION
The invention relates to assemblies of a wire and an electrical contact, and methods of manufacture of such assemblies .
BACKGROUND OF THE INVENTION
Electrical connectors usually comprise a housing in which electrical wires terminated by respective electrical contacts are inserted. The electrical contact is shaped to be electrically contacted by a complementary contact of a mating connector, and also to be locked in the housing.
The electrical contact is sometimes placed in electrical connection with the electrical core of the wire by crimping. It is of paramount importance that this crimping area be protected from any ingress of adverse matter. This is usually done by using a rear end portion of the electrical contact which surrounds the front end of the wire sheath, and by sealing the interface between this assembly and the connector housing.
In order to improve the sealing efficiency, US 2002/096,352 contemplates the use of a groove in the electrical contact to receive a ring-shaped seal. Crimping is then applied on the whole rear end of the electrical contact .
However, this process is rather complex. Further, since the material of the seal is highly incompressible, there is a doubt as to the reliability of this process. It is likely that this crimping process would indeed rather cause tearing of the seal or permanent deformation of the electrical contact around the seal, and thus be adverse to the desired effect.
An object of the invention consists in mitigating at least partially those drawbacks. SUMMARY OF THE INVENTION
It is provided an electrical wire with an electrically conducting longitudinal core, and an electrically insulating outer sheath around said core, wherein said core has a connection end which longitudinally protrudes from the outer sheath at one end of the electrical wire.
A seal made of an incompressible material is provided around said electrically insulating outer sheath.
An electrical contact has a front portion for electrical contact with a mating contact, and a rear portion assembled to the electrical wire.
The rear portion comprises:
an electrical connection portion, nearer the front portion, and crimped on the connection end of the core,
a rear end portion, continuously peripherically surrounding the seal, and with an open end sized to allow forced insertion of the seal therein, along the sheath.
With these features, the electrical connection between the electrical contact and the core of the wire is efficiently performed by crimping. The seal is easily and efficiently placed in position. The rear end portion is not crimped around the seal, and consequently not deformed allowing a reliable sealing between the crimped area of the wire and the portion of the wire not located within the terminal .
In some embodiments, one might also use one or more of the features defined in the dependent claims.
BRIEF DESCRIPTION OF THE DRAWINGS
Other characteristics and advantages of the invention will readily appear from the following description of one of its embodiments, provided as a non- limitative example, and of the accompanying drawings. On the drawings :
Fig. 1 is a perspective front view of an embodiment of an electrical connector,
Fig. 2 is a sectional view along line II-II on Fig. 1 of the connector of Fig. 1, and
Fig. 3 is a detailed partial half-sectional view of the insertion of the contact in the housing.
On the different Figures, the same reference signs designate like or similar elements.
DETAILED DESCRIPTION
Fig. 1 schematically shows an electrical connector 1 comprising an electrically insulating housing 2 defining a plurality of pathways 3. Each pathway receives an electrical contact 4 which is maintained in the connector housing. The electrical contact 4 is shaped to be electrically contacted with a complementary contact borne by a complementary electrical connector (not shown) to be mated with the electrical connector 1.
The electrical contact can be made by bar turning, and has a rotational symmetry around a central axis.
The electrical contact 4 is in fact assembled at the front end of an electrical wire 5 visible on Fig. 2. The assembly of the wire 5 and the contact 4 is mounted in the housing 2 from the rear, and the contact 4 is maintained in the pathway by any suitable means. For example, each contact 4 is assembled to a common rear grid 6 by any suitable way, such as the rear grid 6 having a lock 17 at the end of a flexible arm 18 and which is biased inside a complementary groove 20 of the contact 4. The rear grid 6 may itself be locked to the housing 2 in any suitable way, such as by snap-fitting 19 or the like. Other embodiments are possible.
The contact 4 comprises a front portion 7 which is shaped complementary to the mating contact, and a rear portion 8. "Front" and "rear" are used relatively to the direction of mating of the connector with respect to the mating connector.
The rear portion 8 is designed for assembly with the wire 5. In particular, the wire 5 comprises a central electrically conductive core 9 surrounded by an electrically insulating sheath 10. Intermediate layers may be provided between the two, such as intermediate shielding and insulating layers. At the front end of the wire, the sheath is removed (stripped) so that a connection end of the core 9 is accessible, protruding from the sheath.
The sheath further carries a seal joint 11 which surrounds the sheath at its front end. This seal joint is made of a suitable incompressible elastomeric material such as silicone.
The rear portion 8 of the electrical contact 4 is a hollow cylindrical cavity which is closed except at its open end 15 through which the wire 5 is inserted.
The rear portion 8 of the electrical contact 4 further comprises an electrical connection portion 12 located closest the front portion 7. It is for electrical connection with the wire 5, in particular with its core 9. In particular, the electrical connection portion 12 comprises a portion which is in close contact with the stripped portion of the wire. This is for example achieved by crimping this portion to the connection end of the core 9. This may lead to a portion of reduced diameter 13 such as shown. An intimate contact of the electrical connection portion with the core is obtained all around the periphery of the contact, in order to improve current transfer without any detrimental hot spot or the like.
Furthest away from the front portion 7 of the contact 4, a rear end portion 14 is provided. The rear end portion is provided to surround the assembly of the sheath 10 and the seal joint 11. The rear end portion 14 is thus provided with an enlarged diameter which is greater than the diameter of the electrical connection portion, and which is sufficiently large to surround both the wire and the seal 11. The rear end portion 14 has an open rear end 15 which has a larger diameter than the sheath, so as to allow forceful insertion of the seal 11 along the sheath, through the rear end, between the rear end portion and the sheath. Hence, sealing is provided very close to the electrical connection area between the wire and the contact, for an improved sealing efficiency. No further deformation (e.g. no crimping) is applied on the rear end portion of the contact after the seal 11 is put in place. The sheath is thus maintained on the contact only by retention through the seal 11.
It should be noted that sealing may be further improved, as shown on Fig. 3, by providing extra sealing between the assembly of a wire, a contact and a seal, as it has been described above, and the housing 2. An additional seal 16 may be provided between the outer surface of the electrical contact 4 and the housing 2. This seal may be made of the same material as the seal 11.
To assemble the above assembly, it is provided a wire with a stripped front end. A seal 11 is slid along the sheath 12. The contact is placed on the wire end, and the electrical connection portion is crimped on the core. The rear end portion of the contact is not crimped. The seal 11 is inserted through the open end of the contact between the rear end portion of the contact and the sheath. These operations can be performed for many wires which are assembled together as a cable 21. The contact is driven inside the pathway, and is assembled to the housing for example through the rear grid. A harness may comprise several of these wired connectors.
