Description

Wire harness

The present invention relates to a wire harness including a terminal-attached electric wire and a connector portion formed using the end portion as an insert portion.

A wire harness mounted on an automobile may be required to have high waterproofness at a portion where the end of the electric wire and the terminal fitting are connected. In this case, a connector, which is a resin molded portion that seals a water stop region extending from a part of the terminal fitting to the portion of the insulation coating of the electric wire, is provided. The waterproof resin molded portion (connector) is referred to as a molded connector or the like.

The waterproof connector is made of a synthetic resin that is insert-molded with the water-stop region of the terminal-attached electric wire as an insert portion. And the connector for waterproofing is inserted in the frame part of the housing | casing which accommodates the apparatus which becomes a connection partner of a wire harness. Thereby, a connector fills the clearance gap between an electric wire with a terminal, and a housing | casing. In addition, an annular packing that is sandwiched between the outer peripheral surface of the connector and a frame portion that forms the edge of the opening in the housing is attached to the connector.

That is, the waterproof connector (resin molding part) prevents liquid from entering the connection part between the electric wire and the terminal fitting, and further enters the housing from the gap between the wire harness and the frame part of the housing housing the equipment. Prevent the ingress of liquid.

Further, Patent Document 1 discloses a wire having a hard connector portion (resin molding portion) in which a water stop portion, which is a resin molding portion of a thermoplastic elastomer resin plastic material, is formed of a polyethylene-based resin at an end portion of a terminal-attached electric wire. It is shown that the gap between the connector part and the electric wire is filled at the outlet.

On the other hand, in Patent Document 2, an adhesive is formed on an insulating coating of an electric wire that has been subjected to corona discharge treatment or plasma discharge treatment, and a connector portion (resin molded portion) extends from the terminal fitting to the adhesive in the electric wire with terminal. It is shown that it is formed in a region.

By the way, the portion of the insulation coating of the electric wire is easily deformed by the pressure received from the fluid resin during the insert molding. Therefore, when the rigid connector part is molded using the region extending from the wire connection part of the terminal fitting to the insulation coating of the electric wire in the terminal-attached electric wire as an insert part, the variation in the outer dimensions of the connector part is within a predetermined tolerance. It is difficult to suppress.

Especially, when the electric wire insulation coating is made of a rubber material such as silicon rubber, it becomes more difficult to keep the outer dimensions of the connector portion within the tolerance due to the deformation of the insulation coating. Variation in the outer dimensions of the connector part leads to deterioration of the surface roughness of the rubber packing provided in the connector part, and consequently deterioration of the water stop performance between the connector part and the frame part of the housing into which the connector part is fitted. Connected. Furthermore, the insulating coating made of a rubber material may be damaged by the pressure received from the high-pressure fluid resin at the portion of the wire outlet in the insert molding die.

An object of the present invention is to secure a high water-stopping property by suppressing variations in the outer dimensions of a connector part in a wire harness having a resin-molded waterproof connector part.

The wire harness which concerns on the 1st aspect of this invention is equipped with each component shown below.
(1) A 1st component is an electric wire with a terminal which consists of a conductor and the terminal metal fitting connected to each both ends of the conductor.
(2) The second component is a connector part. This connector part consists of the 1st synthetic resin insert-molded by using a part of each said terminal metal fitting of the both ends of the said electric wire with a terminal as an insert part. The connector portion seals a partial region on the contact portion side of the remaining region excluding the contact portion that contacts the connection partner of the terminal-attached electric wire in the terminal fitting.
(3) A 3rd component is a water stop part. This water stop part consists of the 2nd synthetic resin insert-molded by using as the insert part the part ranging from a part of said terminal metal fitting of one end in the said electric wire with a terminal to a part of said terminal metal fitting of the other end. This second synthetic resin is softer than the first synthetic resin. The said water stop part has sealed the whole part between the parts sealed by each said connector part of the both ends in the said electric wire with a terminal.

The wire harness according to the second aspect of the present invention is an aspect of the wire harness according to the first aspect. The wire harness which concerns on a 2nd aspect WHEREIN: The said connector part seals only the intermediate part between the electric wire connection part connected to the said conductor in the said terminal metal fitting, and the said contact part.

The wire harness according to the third aspect of the present invention is one aspect of the wire harness according to the first aspect or the second aspect. In the wire harness according to the third aspect, each of the connector portions collectively holds the terminal fittings of the plurality of electric wires with terminals arranged in parallel. Furthermore, a gap is formed in a portion between the adjacent conductors in the water stop portion that seals the plurality of conductors.

The wire harness according to the fourth aspect of the present invention is one aspect of the wire harness according to any one of the first to third aspects. The wire harness which concerns on a 3rd aspect WHEREIN: The edge part on the opposite side with respect to the said contact part side of the said terminal metal fitting in the said connector part overlaps with the outer side of the edge part on the said terminal metal fitting side in the said water stop part, and is formed. Yes.

The wire harness according to the fifth aspect of the present invention is one aspect of the wire harness according to any one of the first to fourth aspects. In the wire harness according to the third aspect, the second synthetic resin is made of a rubber material.

The wire harness according to the sixth aspect of the present invention is an aspect of the wire harness according to the fifth aspect. In the wire harness according to the sixth aspect, the first synthetic resin includes polybutylene terephthalate, and the second synthetic resin includes silicon.

In each of the above embodiments, the connector portion is made of a relatively hard synthetic resin, and the water stop portion is made of a relatively soft synthetic resin. Moreover, the conductor in the electric wire with a terminal before a water stop part is formed is a bare electric wire or a bus bar which does not have an insulation coating. That is, the water stop portion seals a part of the terminal fitting and the conductor, and also serves as a conductor covering.

And the connector part is a part formed by insert molding using a part of the terminal fitting in the electric wire with terminal as an insert part. That is, the soft member that is easily deformed by the pressure of the injected resin is not included in the insert portion when the connector portion is molded. Therefore, it is possible to suppress variations in the external dimensions of the connector part and increase the surface roughness of the rubber packing provided in the connector part. As a result, a high waterproof property is ensured between the connector part and the frame part of the housing into which the connector part is fitted.

Also, a water stop portion made of a soft synthetic resin is integrally formed from the conductor to part of the terminal fittings at both ends. Therefore, there is no problem of breakage of the insulation coating that occurs when injection molding is performed at a high pressure around the insulation coating made of a soft material such as a rubber material.

Also, the soft synthetic resin constituting the water stop portion has better adhesion to the water stop region of the electric wire with terminal than the hard synthetic resin. Therefore, the soft water stop part which covers the water stop area | region of an electric wire with a terminal exhibits high water stop performance. Further, the soft water stop does not hinder the ease of bending of the conductor.

As described above, if the wire harness according to each of the above aspects is employed, it is possible to suppress a variation in the external dimensions of the connector portion and ensure high water-stopping.

By the way, the electric wire connection part of the terminal fitting is a part where the variation in shape is likely to occur. When such an electric wire connection part is included in the insert part at the time of shaping | molding of a connector part, there exists a possibility that the dimensional accuracy of a connector part may deteriorate.

In the second aspect, the connector portion is a portion that is insert-molded with an intermediate portion of the terminal fitting in the electric wire with terminal as an insert portion. That is, neither a soft member that easily deforms nor an electric wire connection part of a terminal metal fitting whose shape tends to vary is included in the insert part when the connector part is molded. As a result, the variation in the outer dimensions of the connector portion is further suppressed, and the water stoppage is further increased.

Further, in the third aspect, a gap is formed in a portion between adjacent conductors in the water stop portion that seals the plurality of conductors. Thereby, a water stop part can be comprised with a comparatively small amount of material, and it leads to the weight reduction and cost reduction of a wire harness. Furthermore, the conductor portion is more easily bent.

Further, in the fourth aspect, the edge of the region covering the terminal fitting in the connector portion is formed so as to overlap the outer edge of the water stop portion. Therefore, the soft water-stop part which is easy to deform is prevented from turning up from the electric wire with terminal at the edge.

Further, in the fifth embodiment, the synthetic resin of the water stop portion that also serves as the conductor coating is made of a rubber material that is very easily deformed. Such a water stop part is suitable when it is necessary to easily bend a thick conductor through which a large current flows.

Further, in the sixth aspect, the connector part containing polybutylene terephthalate and the water stop part containing silicon are easily bonded without a gap by the action of the intermolecular force of the hydroxyl group present at each molecular terminal. Therefore, by forming the water stop portion in contact with the connector portion, the water stop and robustness of the connector portion and the entire water stop portion are enhanced.

It is a top view of wire harness 10 concerning a 1st embodiment of the present invention. 2 is a side view of an end portion of the wire harness 10. FIG. 2 is a cross-sectional view of an end portion of the wire harness 10. FIG. It is a top view of the wire harness 10 which concerns on 2nd Embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example embodying the present invention, and is not an example of limiting the technical scope of the present invention.

The wire harness according to each embodiment shown below is a high-voltage wire harness. For example, in an electric vehicle such as a hybrid vehicle or an electric vehicle, the high voltage system wire harness is laid between an inverter circuit and a motor, or between a charging port and a charging circuit.

<First Embodiment>
First, the configuration of the wire harness 10 according to the first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the wire harness 10 includes a terminal-attached electric wire 90, and a connector portion 1 and a water stop portion 2 provided at an end portion of the terminal-attached electric wire 90. Further, a packing part 3 is formed on the connector part 1. For convenience, in FIGS. 1 and 2, a net pattern is shown on the water stop portion 2 and the packing portion 3.

<Wire with terminal>
The terminal-attached electric wire 90 includes a conductor 9 and a terminal fitting 8 connected to the end of the conductor 9. In the terminal-attached electric wire 90 before the water stop portion 2 is formed, the insulating coating is not formed. In the example shown in FIGS. 1 to 3, the wire harness 10 includes a plurality of electric wires 90 with terminals.

The conductor 9 is made of, for example, a metal material such as copper, a copper alloy, or an aluminum alloy, and is formed in a long linear shape or plate shape. For example, if the conductor 9 is a stranded wire composed of a plurality of strands, it is easy to bend. It is also conceivable that the conductor 9 is a bus bar made of a single long plate-like conductor or a laminated bus bar having a structure in which a plurality of plate-like conductors are laminated.

The terminal fitting 8 is a terminal connected to the end of the conductor 9. The terminal fitting 8 is a fitting made of a metal material such as copper or a copper alloy. The terminal fitting 8 has a wire connection part 82, a contact part 81 and an intermediate part 83.

The wire connecting part 82 is a part connected to the end of the conductor 9. For example, the wire connecting portion 82 is a portion where a crimped portion that is crimped to the end portion of the conductor 9 is formed. Alternatively, it is also conceivable that the wire connection portion 82 is a portion welded to the end portion of the conductor 9 by ultrasonic welding or resistance welding.

The contact portion 81 is a portion that contacts a connection partner of the terminal-attached electric wire 90. In the example shown in FIG. 1, the contact portion 81 is a flat plate portion having a through hole through which a screw is passed. However, it is also conceivable that the contact portion 81 is formed in other shapes such as a plate shape or a rod shape without a through hole.

The intermediate part 83 is a part between the wire connecting part 82 and the contact part 81. In the example shown in FIGS. 1 to 3, the intermediate portion 83 has a flat plate shape. However, it is conceivable that the intermediate portion 83 is formed in another shape such as a bent plate shape or a round bar shape.

<Connector part>
The connector portion 1 is a portion made of a synthetic resin that is insert-molded using a part of each of the terminal fittings 8 at both ends of the terminal-attached electric wire 90 as an insert portion. Therefore, a soft member such as an insulating coating that is easily deformed by the pressure of the injected resin is not included in the insert portion when the connector portion 1 is molded.

In the present embodiment, the connector portion 1 is a portion that is insert-molded using only the intermediate portion 83 of the terminal fitting 8 as an insert portion. In this case, neither the soft member that easily deforms due to the pressure of the injected resin nor the wire connection portion 82 of the terminal fitting 8 whose shape tends to vary is included in the insert portion when the connector portion 1 is molded.

The connector part 1 is a hard member, and seals a partial area on the contact part 81 side in the remaining area (water stop area) excluding the contact part 81 in the terminal fitting 8.

The connector portion 1 in this embodiment is in close contact with the surface of the intermediate portion 83 of the terminal fitting 8 over the entire area in the circumferential direction. Therefore, the connector part 1 seals the intermediate part 83 of the terminal fitting 8. The connector part 1 in this embodiment seals only the intermediate part 83 in the terminal fitting 8 and does not contact the wire connection part 82 and the contact part 81.

The synthetic resin constituting the connector part 1 is, for example, a synthetic resin mainly composed of polybutylene terephthalate (PBT). In addition, it is also conceivable that the connector portion 1 is a molded member made of a synthetic resin mainly composed of polyamide 6T (PA6T), polypropylene (PP), acrylonitrile / butadiene / styrene copolymer synthetic resin (ABS resin), or the like.

In the wire harness 10, each of the connector parts 1 at both ends collectively holds the terminal fittings 8 of the plurality of electric wires 90 with terminals arranged in parallel. That is, each connector section 1 holds a plurality of terminal fittings 8 arranged in parallel with a certain positional relationship with an interval. Thereby, each of the both ends of the plurality of terminal-attached electric wires 90 is held in a fixed positional relationship with the gaps arranged in parallel.

In the example shown in FIGS. 1 to 3, the connector portion 1 has an opening 12 for accessing the terminal fitting 8. The opening 12 is closed by a lid member (not shown) after the contact portion 81 of the terminal fitting 8 is connected to the terminal portion of the counterpart device by a screw or the like.

<Water stop part>
The water stop portion 2 is a member made of synthetic resin that is insert-molded with a portion extending from a part of the terminal fitting 8 at one end to a part of the terminal fitting 8 at the other end of the terminal-attached electric wire 90 as an insert portion.

The water stop portion 2 in the present embodiment seals the region of the terminal-attached electric wire 90 from the boundary 84 of the intermediate portion 83 of the terminal fitting 8 at one end to the boundary 84 of the intermediate portion 83 of the terminal fitting 8 at the other end. ing. That is, the water stop part 2 is the whole area | region which is not connected with the terminal metal fitting 8 in the conductor part 9 among the water stop area | regions of the terminal metal fitting 8 of the both ends of the electric wire 90 with a terminal in the connector part 1 and the conductor 9. And sealed.

Moreover, the water stop part 2 consists of a synthetic resin softer than the synthetic resin which comprises the connector part 1. FIG. For example, the water stop part 2 consists of a silicone type synthetic resin which has elasticity in the shape | molded state. Alternatively, it is also conceivable that the water stop portion 2 is made of a relatively soft synthetic resin such as an elastomer other than silicon, a polyamide resin, or a polyester resin.

The connector part 1 and the water stop part 2 are formed by so-called two-color molding. Accordingly, the water stop portion 2 is in contact with the connector portion 1. In the two-color molding, the water stop portion 2 is molded after the connector portion 1 is molded.

More specifically, after the insert molding of the connector portion 1 is performed, the wire connection portion 82 of the connector portion 1 at the other end from the edge portion 11 on the wire connection portion 82 side of the connector portion 1 at the one end of the electric wire 90 with terminal. Insert molding of the water stop portion 2 is performed using the region up to the side edge portion 11 as an insert portion.

In the wire harness 10, it is conceivable that a synthetic resin mainly composed of polybutylene terephthalate is adopted as the material of the connector part 1, and a synthetic resin mainly composed of silicon is adopted as the material of the water stop part 2. Thereby, the connector part 1 and the water stop part 2 are easy to adhere | attach without a space | gap by the effect | action of the intermolecular force of the hydroxyl group which exists in each molecular terminal.

Moreover, in the example shown by FIG.2, 3, the edge part 11 by the side of the electric wire connection part 82 of the terminal metal fitting 8 in the connector part 1 overlaps with the outer side of the edge part 21 by the side of the terminal metal fitting 8 in the water stop part 2. Has been.

Further, as shown in FIGS. 2 and 3, a convex part and a concave part in which a part of the connector part 1 and a part of the water stop part 2 are fitted in a direction intersecting the extending direction (axial direction) of the conductor 9. It is conceivable that the fitting structure 4 including

In the example shown in FIGS. 2 and 3, the concave portion 13 of the connector portion 1 and the convex portion 22 of the water stop portion 2 constitute a fitting structure 4 that fits in a direction orthogonal to the extending direction of the conductor 9.

As shown in FIG. 1, a gap 23 is formed in a portion between adjacent conductors 9 in the water stop portion 2 that seals the plurality of conductors 9. In other words, the plurality of conductors 9 are individually covered with the water stop portions 2 at intermediate portions between both end portions thereof.

<Packing part>
The packing part 3 is an annular elastic member formed along a part of the outer peripheral surface of the connector part 1. The packing portion 3 is formed along the outer peripheral surface of the portion of the connector portion 1 that is fitted into the frame portion 72 of the housing 7 that accommodates a device to which the wire harness 10 is connected. The frame portion 72 is a portion that forms the edge of the opening 71 in the housing 7. 2 and 3, the housing 7 is drawn with a virtual line (two-dot chain line).

When part of the connector part 1 is fitted into the frame part 72 of the housing 7, the packing part 3 is sandwiched between the outer peripheral surface of the connector part 1 and the frame part 72 of the housing 7. Thereby, the packing part 3 fills the gap between the outer peripheral surface of the connector part 1 and the frame part 72 of the housing 7.

For example, it is possible that the packing part 3 is shape | molded with the water stop part 2 using the same material as the water stop part 2. FIG. In this case, at least the portion where the packing portion 3 in the connector portion 1 is formed and the water-stopping portion 2 and the packing portion 3 in parallel by one-time insert molding with the water-stopping region of the terminal-attached electric wire 90 as the insert portion. Molded. The material of the water stop part 2 and the packing part 3 is considered to be an elastic material which has silicon as a main component, for example.

On the other hand, it is also conceivable that the packing part 3 is an independent member attached to the connector part 1.

<Effect>
In the wire harness 10, the connector portion 1 is made of a relatively hard synthetic resin, and the water stop portion 2 is made of a relatively soft synthetic resin. Moreover, the conductor 9 in the electric wire 90 with a terminal before the water stop part 2 is formed is a bare electric wire or a bus bar without an insulating coating. That is, the water stop portion 2 seals a part of the terminal fitting 8 and the conductor 9 and also serves as a covering for the conductor 9.

The connector portion 1 is a portion that is insert-molded with a part of the terminal fitting 8 in the terminal-attached electric wire 90 as an insert portion. That is, a soft member that is easily deformed by the pressure of the injected resin is not included in the insert portion when the connector portion 1 is molded. Therefore, it is possible to suppress variations in the external dimensions of the connector part 1 and increase the surface roughness of the packing part 3 provided in the connector part 1. As a result, a high waterproof property is ensured between the connector part 1 and the frame part 72 of the housing 7 into which the connector part 1 is fitted.

Also, since the soft synthetic resin is generally excellent in fluidity at the time of injection molding, the injection pressure of the fluid resin when the water stop portion is insert-molded can be kept low. Therefore, even if the insulating coating of the electric wire is made of a soft material such as a rubber material, the insulating coating can be prevented from being damaged by the pressure received from the fluid resin.

Further, the water stop portion 2 made of a soft synthetic resin is integrally formed from the conductor 9 to part of the terminal fittings 8 at both ends thereof. Therefore, there is no problem of breakage of the insulation coating that occurs when injection molding is performed at a high pressure around the insulation coating made of a soft material such as a rubber material.

Further, the soft synthetic resin constituting the water stop portion 2 has better adhesion to the water stop region of the terminal-attached electric wire 90 than the hard synthetic resin. Therefore, the soft water stop part 2 which covers the water stop area | region of the electric wire 90 with a terminal exhibits high water stop performance.

As described above, if the wire harness 10 is employed, it is possible to suppress a variation in the outer dimensions of the connector portion 1 and ensure high water-stopping.

In the wire harness 10, the connector portion 1 is a portion that is insert-molded using the intermediate portion 83 of the terminal fitting 8 in the terminal-attached electric wire 90 as an insert portion. In this case, neither the soft member that easily deforms nor the wire connection portion 82 of the terminal fitting 8 that easily causes variation in shape is included in the insert portion when the connector portion 1 is molded. As a result, the variation in the external dimensions of the connector part 1 is further suppressed, and the waterstop is further increased.

Further, in the wire harness 10, a gap 23 is formed in a portion between adjacent conductors 9 in the water stop portion 2 that seals the plurality of conductors 9. Thereby, the water stop part 2 can be comprised with a comparatively small amount of material, and it leads to the weight reduction and cost reduction of the wire harness 10. FIG. Furthermore, the portion of the conductor 9 becomes easier to bend.

Also, the edge 11 on the wire connecting portion 82 side of the terminal fitting 8 in the connector portion 1 is formed so as to overlap the outer side of the edge 21 of the water stop portion 2. Therefore, the soft water stop portion 2 that is easily deformed is prevented from turning up from the terminal-attached electric wire 90 at the edge portion 21. In addition, the edge part 11 of the connector part 1 is an edge part on the opposite side with respect to the contact part 81 side of the terminal metal fitting 8. FIG.

Further, it is conceivable that the synthetic resin of the water stop portion 2 that also serves as the conductor 9 is made of a rubber material that is very easily deformed. The water stop portion made of such a synthetic resin is suitable when it is necessary to easily bend the thick conductor 9 through which a large current flows.

Also, the connector part 1 containing polybutylene terephthalate and the water stop part 2 containing silicon are easily bonded without gaps by the action of the intermolecular force of the hydroxyl group present at each molecular terminal. Therefore, by forming the water stop portion 2 in contact with the connector portion 1, the water stop and robustness of the entire connector portion 1 and the water stop portion 2 are increased.

Second Embodiment
Next, a wire harness 10A according to a second embodiment of the present invention will be described with reference to FIG. This wire harness 10A is different from the wire harness 10 shown in FIGS. 1 to 3 in that it has a branch structure. 4, the same components as those shown in FIGS. 1 to 3 are given the same reference numerals. Hereinafter, only the differences of the wire harness 10A from the wire harness 10 will be described.

FIG. 3 is a plan view of the wire harness 10A.

As shown in FIG. 4, the wire harness 1 </ b> A has a structure in which a plurality of terminal-attached electric wires 90 are branched in the middle. In the example shown in FIG. 4, the six terminal-attached electric wires 90 are collectively held by one set of connector portion 1A and water stop portion 2A at one end portion, and two sets of connector portions at the other end portion. Each of 1A and water stop part 2A is divided into two pieces and held in three pieces.

Further, the conductor 9A in the wire harness 1A is a long plate-shaped bus bar. In addition, the connector part 1A and the water stop part 2A have the same structure as the connector part 1 and the water stop part 2 only in the number of the electric wires 90 with a terminal used as an insert part differing. The wire harness 1A shown in FIG. 4 is also one embodiment of the present invention.

<Others>
The wire harnesses 10 and 10 </ b> A include a plurality of terminal-attached electric wires 90, and a connector portion 1 and a water stop portion 2 that collectively cover ends of the plurality of terminal-attached electric wires 90. However, it is also considered that the structure of the connector part 1 and the water stop part 2 in the wire harnesses 10 and 10A is applied to one electric wire 90 with a terminal.

In the wire harness according to the present invention, the embodiments described above can be freely combined within the scope of the invention described in each claim, or each embodiment can be appropriately modified or partially omitted. It is also possible to constitute by doing.
