Definitions
- the present invention relates to a sealed overmolded electric cable and to a method for producing such a cable. More particularly, it is an electric cable intended to be installed in a motor vehicle.
- a motor vehicle is intended to meet all kinds of traffic conditions, climatic conditions, loads, etc.
- all equipment mounted on a vehicle must be capable of showing fault-free operation regardless of the conditions of movement of the vehicle.
- the electrical devices on board the vehicle have a tight seal, not only to water, but also to fuels, engine fluids, etc.
- Such overmolded cables are widely used, for example for wheel speed sensors, connectors overmolded on cable, etc., but also in other less severe environments.
- the present invention aims to obtain an optimum seal between the cable and the overmolded material.
- the present invention relates to an overmolded electric cable comprising on the one hand: - a cable of the type comprising a plurality of insulated conductive wires inside an insulating sheath, and
- the said overmolded cable being characterized in that: - at least one groove is produced on the external surface of the insulating sheath, the said groove being suitable for receive the overmolding material.
- at least one fin forming an integral part of the sheath is produced in the groove.
- the overmolded material cooperates not only with the groove produced in the sheath to ensure an adhesive seal, but also with the fin (s) to ensure a cohesive seal.
- the cooperation between the groove and the overmolded material makes it possible to perfectly adhere even partially these two materials to each other throughout the range of their operating temperature and whatever their respective coefficient of expansion, while the cooperation of the fins and the overmolding material causes at least partial melting of the fins, which ensures, after cooling, an intimate cohesion between the two materials.
- the profile of the fin affects its ability to merge with the overmolding material. Preferably, the finer the fin, the easier it is to obtain its fusion. However, it must be ensured that the quantity of material coming from the fin remains in sufficient quantity to create a homogeneous cohesion.
- grooves block the differential expansion which may occur between the material of the sheath and that of overmolding.
- the fins for their part, by partial or total reflow, cohesion of the two materials.
- seal obtained according to the present invention is independent of the diameter of the cable and the surface condition of the sheath.
- the seal (by grooving) is also independent of the pair of material chosen (cable and overmolding material) as well as the design of the overmolding mold and the parameters of implementation of the overmolding material.
- the height of the fins produced is less than the depth of the groove. Therefore, when the cable is handled before carrying out the overmolding operation, the fins are protected against any pollution by contact (in particular grease) which could deteriorate the cohesion between the fins and the overmolding material deposited subsequently.
- the present invention also relates to a method for producing an overmolded cable. This process consists in particular in:
- the method according to the invention also consists in creating at least one fin in the groove produced.
- FIG. 1 is a schematic sectional view showing a cable according to the invention before the overmolding operation
- FIG. 2 is a schematic detail view of a groove according to the invention.
- a cable 10 molded according to the present invention comprises an insulating sheath 11 ( Figure 1) wrapping a plurality of conductive electrical wires 12 (two in the example shown). Each of these conductive wires 12 is sheathed, in a manner known per se, in an insulating material. It should be noted that the insulating sheath 11 has a relatively large thickness as well as a certain rigidity, even if it remains flexible. This sheath is generally made of an elastomeric thermoplastic material or the like.
- At least one groove 13 (three in the example shown) is produced in the thickness of this sheath, generally in the form of a U. This groove does not entirely perforate the sheath and is produced on the external surface of the sheath 11.
- Each of these grooves 13 has inside at least one fin 14 (two in the example shown). These fins are also produced in the thickness of the sheath and do not pass right through.
- the groove 13 is generally U-shaped.
- the fins 14, on the other hand, have a section which decreases as one moves away from the bottom of the groove. The usefulness of this decrease will be explained below.
- the cable shown in FIGS. 1 and 2 is overmolded by an overmolding material 15.
- this overmolding makes it possible to produce a complete electrical component, such as the sensor shown by way of example in FIG. 3.
- a complete electrical component such as the sensor shown by way of example in FIG. 3.
- the realization of the rest of this sensor being known per se, it will not be explained here.
- the overmolding material 15 which is generally a thermoplastic material such as polyamide filled with glass fibers (or the like)
- the overmolding material comes into contact on the one hand, the walls 13a 13b, 13c (FIG. 2 ) of the groove and on the other hand, with the fins 14.
- the entire groove 13 is filled with this overmolding material. On cooling, this material strongly adheres to the walls 13a, 13b, 13c of this groove. A first form of sealing called adhesive is thus produced.
- the cable according to the invention thus comprises a plurality of grooves 13, each comprising a plurality of fins 14.
- the apex S of the fins is arranged in a plane situated below the plane P of the sheath 11.
- the height h of the fins is less than the depth p of the groove. Therefore, when the grooves and the fins are made but the overmolded material is not yet in place, it is possible to manipulate the insulating sheath without polluting it by contact. In particular, it is avoided that any manipulation of the sheath which is not yet overmolded deposits traces of fatty substance (or other) on the top of the fins, which could subsequently harm the good cohesion of the fins and of the molding material 15. It should be noted that any modification of the profile of the fins causes a modification of the degree of tightness. Thus, for specific applications, it is possible, by modifying this profile, to adapt the seal to the requirements requested.
- the present invention also relates to a method for producing an overmolded electric cable comprising:
- this method also includes a step in which at least one fin 14 is produced in the groove 13, and this, prior to the overmolding of this groove.
