The embodiment of the application provides a wire harness assembly. The harness assembly is applied to the charging socket, and the risk that a cable of the charging socket is easy to break is reduced.

Referring to fig. 1 to 3, a wire harness assembly includes a flat cable 1 and a connection terminal 2, one end of the flat cable 1 being soldered to the connection terminal 2;

the flat cable 1 includes at least two conductors 12, and at least two of the conductors 12 are arranged at a distance from each other in the width direction of the flat cable 1.

The conductor 12 is bent in the thickness direction of the flat cable 1 to form a deformed section 121 and a connection section 122, and the deformed section 121 and the connection section 122 are connected.

The projected length of the deformed segment 121 on the end face 11 of the flat cable 1 is less than or equal to one half thickness dimension of the conductor 12. Wherein the thickness dimension of the conductor 12 is a dimension in the thickness direction of the flat cable 1;

the connection section 122 extends in the longitudinal direction of the flat cable 1, and the connection section 122 is soldered to the connection terminal 2.

In the embodiment of the present application, the wire harness assembly includes the flat cable 1 and the connection terminal 2. When the flat cable 1 is soldered to the connection terminal 2 (see fig. 1, a, which shows the soldering position of both), the conductors 12 of the flat cable 1 deform under the pressing force of the soldering head. After the conductors 12 of the flat cable 1 are deformed, the flat cable 1 contacts the connection terminals 2 and the two are soldered together by a soldering head. Since the cable of the wire harness assembly is the flat cable 1 (the structure of the cable is a flat structure, specifically, the dimension in the width direction of the cable is larger than the dimension in the thickness direction of the cable), when the flat cable 1 and the connection terminal 2 are welded together by the welding head, the conductor 12 of the flat cable 1 is deformed to a small extent in the thickness direction of the flat cable 1, and the conductor 12 of the flat cable 1 is less likely to undergo a wire breakage phenomenon.

When the flat cable 1 is soldered to the connection terminal 2, the conductor 12 of the flat cable 1 is bent in the thickness direction of the flat cable 1 under the pressing force of the soldering head to form the deformed section 121 and the connection section 122, and the deformed section 121 and the connection section 122 are connected. For example, the soldering tip presses the conductor 12 at the junction of the deformed section 121 and the connection section 122, and the conductor 12 is bent in the thickness direction of the flat cable 1 to form the deformed section 121 and the connection section 122.

The deformation section 121 formed by bending the conductor 12 in the thickness direction of the flat cable 1 characterizes the deformation of the flat cable 1, and the projection length of the deformation section 121 on the end face 11 of the flat cable 1 characterizes the deformation degree of the deformation of the flat cable 1, wherein the deformation degree can be understood as the height difference formed by bending the conductor 12.

Wherein "the end face 11 of the flat cable 1" can be understood as: exposing the surface of the conductor 12 of the flat cable 1; it can also be understood that: at the surface of the end of the flat cable 1. Wherein the flat cable 1 has two ends, wherein one end of the flat cable 1 exposes the conductor 12, the conductor 12 is connected with the connection terminal 2, and the other end of the flat cable 1 is connected with a battery pack in a vehicle.

Wherein when the flat cable 1 is welded with the connection terminal 2, the conductor 12 of the flat cable 1 is deformed, and wherein the projection length of the deformed section 121 on the end face 11 of the flat cable 1 is less than or equal to one half of the thickness dimension of the conductor 12, the deformation degree of the conductor 12 of the flat cable 1 is smaller, and the risk of breakage of the flat cable 1 is reduced.

Specifically, in the prior art, the cable of the charging socket is a round cable, a conductor is arranged in the round cable, and the diameter of the conductor in the round cable is larger, generally about 17 mm. When the conductor in the circular cable is welded with the connecting terminal, the conductor in the circular cable is larger in deformation under the action of the pressing force of the welding head, and the conductor is easy to break. For example, in the length direction of the round cable, the round cable and the connection terminal are opposite, the welding position of the round cable and the connection terminal is at the center line of the round cable, and at this time, the deformation of the conductor of the round cable is half the conductor diameter of the round cable, that is, the deformation degree of the conductor of the round cable in the radial direction of the round cable is 8.5mm.

In the embodiment of the present application, the cable of the charging socket is designed as the flat cable 1, wherein the flat cable 1 includes at least two conductors 12, and the at least two conductors 12 are disposed apart in the width direction of the flat cable 1. That is, the flat cable 1 has at least two conductors 12 without affecting the current-carrying capacity of the cable of the charging socket, so that the flat cable 1 has the same current-carrying capacity as the round cable, even the flat cable 1 has a larger current-carrying capacity with respect to the round cable.

The dimension of the conductor 12 of the flat cable 1 in the thickness direction of the flat cable 1 is smaller than the diameter dimension of the conductor of the round cable, and when the flat cable 1 is welded with the connection terminal 2, the deformation degree of the conductor 12 of the flat cable 1 in the thickness direction of the flat cable 1 is small, so that the risk of breakage of the flat cable 1 is reduced. For example, the dimension of the conductor 12 of the flat cable 1 in the thickness direction of the flat cable 1 is 9mm, and the degree of deformation of the conductor 12 of the flat cable 1 in the thickness direction of the flat cable 1 is 4.5mm. It follows that the degree of deformation of the conductors 12 of the flat cable 1 in the thickness direction of the flat cable 1 is smaller than the degree of deformation of the conductors 12 of the round cable in the radial direction of the round cable, and therefore the flat cable 1 reduces the risk of breakage of the flat cable 1 when soldered to the connection terminal 2.

Therefore, in the embodiment of the present application, the harness assembly applied to the charging socket includes the flat cable 1 and the connection terminal 2, and the risk of breakage of the flat cable 1 is reduced when the flat cable 1 is soldered to the connection terminal 2.

In addition, the cable of the harness assembly is the flat cable 1, and in the condition that the total number of the cores of the conductors 12 of the flat cable 1 is the same as that of the round cable, the flat cable 1 has better heat dissipation than the round cable. The flat wire cable heat dissipation capacity is strong, has bigger current bearing capacity, lower inductance and faster current transmission speed, and wire harness assembly is applied to the charging socket, and the charging socket is better for vehicle battery package charging effect.

In one embodiment, referring to fig. 1, the flat cable 1 and the connection terminals 2 are opposed to each other along the length direction of the flat cable 1, and the connection terminals 2 are located at the center position in the thickness direction of the flat cable 1.

Specifically, when the flat cable 1 is soldered to the connection terminal 2, the positional relationship between the flat cable 1 and the connection terminal 2 is: in the length direction of the flat cable 1, the flat cable 1 and the connection terminals 2 are arranged opposite to each other, and the risk of breakage of the flat cable 1 is reduced. For example, in the thickness direction of the flat cable 1, the connection terminal 2 is located at the center of the thickness direction of the flat cable 1, and when the flat cable 1 is soldered to the connection terminal 2, the deformation degree of the conductor 12 of the flat cable 1 is small, and the risk of breakage of the conductor 12 is reduced.

In one embodiment, referring to fig. 2, the connection section 122 has a side surface, and the side surface of the connection section 122 is welded to the connection terminal 2.

In this embodiment, after the conductors 12 of the flat cable 1 are bent in the thickness direction of the flat cable 1 to form the connection sections 122, the connection sections 122 are soldered to the connection terminals 2. Specifically, the side of the connection section 122 is welded with the connection terminal 2, increasing the contact area of the connection section 122 and the connection terminal 2, and improving the connection strength of the connection section 122 and the connection terminal 2.

Where "the side of the connecting section 122" can be understood as: the surfaces in the circumferential direction of the connection section 122 are both side surfaces of the connection section 122. I.e. the connecting section 122 comprises an end surface (the surface at the end of the connecting section 122) and a side surface, the surface of the end face 11 of the connecting section 122 being removed, the remaining surfaces being the side surfaces of the connecting section 122.

In one embodiment, the deformed section 121 is a linear conductor 12, and a length dimension of the deformed section 121 in the thickness direction of the flat cable 1 is less than or equal to one half of the thickness dimension of the conductor 12.

In this embodiment, the deformed segment 121 is a linear conductor 12, and the projected length of the deformed segment 121 on the end face 11 of the flat cable 1 coincides with the length dimension of the deformed segment 121 in the thickness direction of the flat cable 1. When the flat cable 1 and the connection terminal 2 are soldered together, the length dimension of the deformed segment 121 is less than or equal to one-half the thickness dimension of the conductor 12, reducing the risk of breakage of the conductor 12. For example, the length dimension of the deformed segment 121 formed by bending the conductor 12 near the center line of the flat cable 1 (the center line is the center line in the thickness direction of the flat cable 1) is smaller than one half of the thickness dimension of the conductor 12; the length dimension of the deformed segment 121 formed by bending the conductor 12 at the position farthest from the center line of the flat cable 1 (the center line is the center line in the thickness direction of the flat cable 1) is equal to the thickness dimension of one half of the conductor 12.

For example, after the conductor 12 is bent in the thickness direction of the flat cable 1, the conductor 12 is divided into three parts including a body section 123, a deformed section 121 and a connecting section 122, wherein one end of the deformed section 121 is connected with the body section 123, the other end of the deformed section 121 is connected with the connecting section 122, wherein an included angle formed between the body section 123 and the deformed section 121 is 90 °, and an included angle formed between the deformed section 121 and the connecting end is 90 °. In this embodiment, after the flat cable 1 is bent, the degree of deformation of the flat cable 1 is small, that is, the height difference formed between the body section 123 and the connection section 122 is small, and the risk of breakage of the conductor 12 is reduced.

In one embodiment, referring to fig. 2, the conductor 12 is bent in the thickness direction of the flat cable 1 to form a body section 123, one end of the deformation section 121 is connected to the body section 123, the other end of the deformation section 121 is connected to the connection section 122, wherein an included angle formed between the body section 123 and the deformation section 121 is an obtuse angle, and an included angle formed between the deformation section 121 and the connection section 122 is an obtuse angle.

Specifically, after the conductor 12 is bent in the thickness direction of the flat cable 1, the conductor 12 is divided into three parts, the three parts include a body section 123, a deformed section 121 and a connecting section 122, wherein one end of the deformed section 121 is connected with the body section 123, the other end of the deformed section 121 is connected with the connecting section 122, an included angle formed between the body section 123 and the deformed section 121 is an obtuse angle, and an included angle formed between the deformed section 121 and the connecting section 122 is an obtuse angle. In this embodiment, the included angle formed between the body section 123 and the deformed section 121, and the included angle formed between the deformed section 121 and the connecting section 122 are defined, further reducing the risk of breakage of the conductor 12. In this embodiment, after the flat cable 1 is bent, the degree of deformation of the flat cable 1 is small, that is, the height difference formed between the body section 123 and the connection section 122 is small, and the risk of breakage of the conductor 12 is reduced.

For example, the flat cable 1 is deformed by the pressing force of the welding head, wherein the deformed section 121 is the inclined conductor 12, specifically, the deformed section 121 is the conductor 12 inclined toward the direction away from the end face 11 of the flat cable 1.

Wherein the end face 11 defining the conductor 12 is rounded in shape, so that the welding head exerts a force on the conductor 12 to weld the conductor 12 and the connection terminal 2.
