Definitions
- the present invention relates to an overmolded electric cable waterproof and a method of making such a cable.
- he is an electrical cable intended to be placed in a vehicle automobile.
- a motor vehicle is intended to meet all kinds of traffic conditions, climatic, load, etc.
- all vehicle-mounted equipment must be capable of showing a fault-free operation whatever the conditions of moving the vehicle.
- the apparatus on-board electrical equipment have a high degree of only with water, but also with fuels, motor fluids, etc.
- This sealing is, of course, also necessary at the level of the power supply of these different components, and therefore at the level of introducing the power cable into an electrical component.
- Such overmolded cables are widely used, for example for wheel speed sensors, over-molded connectors on cable, etc., but also in other less severe environments.
- the present invention aims to obtain optimum sealing between the cable and the overmoulded material.
- At least one fin forming an integral part of the sheath is made in the groove.
- the overmoulded material cooperates with only with the groove made in the duct to ensure a tightness adhesive, but still with the wing or fins to ensure a seal cohesive.
- the cooperation between the groove and the overmolded material allows to perfectly adhere even partially these two matters to each other throughout the range of their operating temperature and whatever their 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 fin profile influences its ability to merging with the overmoulding material.
- the fin is finer and the easier it is to get a merger.
- it must be ensured that the quantity of material from the fin remains in sufficient quantity to create cohesion homogeneous.
- the grooves ensure a blocking of the expansion differential between the material of the sheath and that of overmolding.
- the fins ensure, for their part, by partial reflow or total, a cohesion of the two materials.
- the seal obtained according to the present invention is independent of the cable diameter and the surface condition of the sheath.
- the sealing (grooving) is also independent of the material pair chosen (cable and overmoulding material) as well as the design of the mold of overmoulding and implementation parameters of the overmoulding material.
- the height of the fins produced is less than the depth of the groove.
- the method according to the invention also consists in creating at least one fin in the groove made.
- a cable 10 overmoulded according to the present invention comprises an insulating sheath 11 (FIG. 1) coating a plurality of conductive electrical wires 12 (two in the example represent). Each of these conductive wires 12 is sheathed in a manner known in itself, in an insulating material.
- the insulating sheath 11 has a thickness relatively important as well as a certain rigidity, even if it remains flexible.
- This sheath is generally made of a thermoplastic material elastomer or the like.
- this sheath is made in the thickness of this sheath at least one groove 13 (three in the example shown), generally shaped This groove does not completely perforate the sheath and is made on the surface outer sheath 11.
- Each of these grooves 13 has inside it at least one fin 14 (two in the example shown). These fins are also realized in the thickness of the sheath and do not go through it.
- the groove 13 is generally in The fins 14, on the other hand, have a section which decreases as and when as one moves away from the bottom of the groove. The usefulness of this decline will be explained later.
- the cable shown in Figures 1 and 2 is overmolded by a molding material 15.
- this overmolding makes it possible to produce a component electrical circuit, such as the sensor shown by way of example in FIG. realization of the rest of this sensor being known per se, it will not be explained right here.
- the overmoulding material comes into contact with, on the one hand, the walls 13a, 13b, 13c ( Figure 2) of the groove and secondly, with the fins 14.
- the entire groove 13 is filled by this material of overmolding. By cooling, this material strongly adheres to the walls 13a, 13b, 13c of this groove. A first form of so-called adhesive sealing is thus performed.
- the contact of the overmoulding material with the fins 14 causes also the at least partial fusion of these.
- these fins present progressive thinning towards the outside of the groove, the vertex S of wings as soon as the molded material touches them.
- the melting thereof becomes partial.
- a phenomenon of progressive anchoring of the non fondue of the fin in the overmoulding material The part of the wing having fondue causes, for its part, an intimate mixture of the materials in the presence. This fusion and this anchoring create a second form of sealing cohesion.
- the cable according to the invention thus comprises a plurality of grooves 13, each having a plurality of fins 14.
- the top S of the fins is disposed in a plane below the plane P of the sheath 11.
- the height h of fins is less than the depth p of the groove.
- any modification of the profile of the fins causes a modification of the degree of tightness. So, for specific applications, it is possible, by modifying this profile, to adapt the tightness to the requested requirements.
- this method also comprises a step in which is made at least one fin 14 in the groove 13, and this, prior to overmolding this groove.
