Description

The present invention relates to an electric wire with a terminal that waterproofs the connection point between the core wire and the terminal of the electric wire with a shrinkable tube.

As a conventional example of an electric wire with a terminal that is waterproofed with a shrinkable tube, there is one disclosed in Patent Document 1. In this electric wire 50 with terminals, as shown in FIG. 13, the electric wire W in which the core wire 61 is covered with the insulating coating 62 and the core wire 61 of the terminal portion is exposed from the insulating coating 62 and the exposed core wire 61 of the terminal portion are The terminal 51 connected by ultrasonic welding, the elastic ring 70 attached to the terminal 51 at the tip position of the exposed core wire 61 of the terminal portion, and the elastic ring 70 and the exposed core wire 61 and the terminal 51 of the terminal portion. It is provided with a heat-shrinkable tube 80 for sealing the core wire connection portion of the above.

The height h1 of the elastic ring 70 from the terminal surface is formed to be lower than the height h2 of the core wire 61 from the terminal surface. Compared with the case where the elastic ring 70 is not attached, the step from the surface of the terminal 51 is lowered by (h2-h1). As a result, the shrinkage difference when the heat-shrinkable tube 80 is heat-shrinked is reduced, and the tip of the heat-shrinkable tube 80 is in close contact with the entire outer peripheral surface of the terminal 51 (so-called heat-shrinkable tube is closed) to ensure waterproofing. I try to do it.

That is, when the heat-shrinkable tube 80 is used to waterproof the electric wire 50 with a terminal, the front end side of the heat-shrinkable tube 80 is in close contact with the surface of the terminal 51 without a gap, and the rear end side of the heat-shrinkable tube 80 is in close contact with the insulating coating 62 without a gap. There is a need. Since the rear end side of the heat-shrinkable tube 80 (the side that comes into close contact with the insulating coating 62) causes only a small shrinkage, it comes into close contact with the insulating coating 62 without any gap. However, on the tip side of the heat shrinkable tube 80 (the side in close contact with the terminal 51), a large step is formed between the surface of the terminal 51 and the tip of the core wire 61, so that the heat shrinkable tube 80 has no gap in the terminal 51. It may not adhere.

In order to solve this problem, in the conventional example, the elastic ring 70 is arranged at a position in front of the tip surface of the core wire 61.

Japanese Unexamined Patent Publication No. 2016-184493

However, in the conventional electric wire 50 with terminals, the elastic ring 70 may be misaligned when the heat-shrinkable tube 80 is shrunk, which may impair the waterproof performance.

Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an electric wire with a terminal that can surely ensure waterproofness.

In the present invention, the core wire is covered with an insulating coating, the electric wire whose core wire of the terminal portion is exposed from the insulating coating, and the exposed core wire of the terminal portion are connected by ultrasonic welding, and the core wire is crimped. A terminal having a core wire crimping portion to be connected, an exposed core wire of the terminal portion, and a shrinkable tube for sealing the core wire crimping portion are provided, and the tip height of the core wire protruding from the core wire crimping portion is before connection. It is characterized in that the entire upper portion of the connection portion of the exposed core wire of the terminal portion or the upper portion on the tip side is cut and removed to form the core wire lower than the height of the core wire covered with the insulating coating. It is an electric wire with a terminal.

According to the present invention, since the height of the tip of the core wire from the surface of the terminal itself is low, waterproofness can be reliably ensured.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First Embodiment)
1 and 2 show a first embodiment of the present invention. The electric wire 1A with a terminal of the first embodiment is a heat-shrinkable tube that seals an electric wire W whose core wire 11 is covered with an insulating coating 12, a terminal 2 connected to the electric wire W, and a connection portion between the terminal 2 and the electric wire W. (Shrinkable tube) 20 and.

In the electric wire W, the insulating coating 12 of the terminal portion is stripped off, and the core wire 11 of the terminal portion is exposed from the insulating coating 12. The core wire 11 is formed by twisting a large number of strands (not shown). The entire upper part of the exposed core wire 11 of the terminal portion is removed by cutting over the entire area. As a result, the height H1 of the tip of the exposed core wire 11 is formed to be lower than the height H2 of the core wire 11 covered with the insulating coating 12.

The terminal 2 has a flat base portion 3, a core wire crimping portion 4 extending from both side ends of the base portion 3, and a covering crimping portion 5 extending from both side ends of the base portion 3. A connecting portion 6 is provided at the tip of the base portion 3. A hole 6a is formed in the connecting portion 6. The exposed core wire 11 of the terminal portion is connected (fixed) to the base portion 3 by ultrasonic welding. The exposed core wire 11 of the terminal portion is crimped to the terminal 2 by the core wire crimping portion 4. The insulating coating 12 near the terminal portion of the electric wire W is crimped to the terminal 2 by the coating crimping portion 5.

The heat-shrinkable tube 20 seals the exposed core wire 11 of the terminal portion and the core wire crimping portion 4. Specifically, the tip of the heat-shrinkable tube 20 is in close contact with the entire outer circumference of the base portion 3 of the terminal 2 without a gap, and the rear end thereof is in close contact with the entire outer circumference of the insulating coating 12 of the electric wire W without a gap. .. The heat-shrinkable tube 20 is substantially in close contact between the front end portion and the rear end portion along the outer contour of the core wire 11 and the terminal 2. In FIG. 1, the heat-shrinkable tube 20 is shown by a virtual line in order to clearly display the accommodation portion in the heat-shrinkable tube 20.

The heat-shrinkable tube 20 has a tubular shape in which the tip side is gradually reduced in diameter as shown in FIG. 2D before shrinking due to heat. In FIG. 1, the heat-shrinkable tube 20 is shown by a virtual line so that the internal portion can be seen.

Next, the manufacturing procedure of the electric wire 1A with a terminal will be described. As shown in FIG. 2A, in the electric wire W, the insulating coating 12 of the terminal portion is removed, and the core wire 11 is exposed. The entire upper part of the connection portion of the exposed core wire 11 of the terminal portion is removed by cutting before welding. Next, as shown in FIG. 2B, the exposed core wire 11 of the terminal portion of the electric wire W is placed on the base portion 3 of the terminal 2 and ultrasonically welded. With this, the core wire 11 and the base portion 3 of the terminal 2 are welded. In ultrasonic welding, a compressive force is applied to the core wire 11 and the core wire 11 is slightly melted, so that the height of the core wire 11 is slightly lowered.

Next, as shown in FIG. 2C, the insulating coating 12 near the terminal portion of the electric wire W is crimped and crimped by the coating crimping portion 5, and the exposed core wire 11 of the terminal portion of the electric wire W is crimped to the core wire crimping portion 4. Crimping and crimping with. Next, as shown in FIG. 2D, the heat-shrinkable tube 20 is inserted at a position that completely covers the exposed core wire 11 (in FIG. 2D, the accommodation portion in the heat-shrinkable tube 20 is clearly defined. The heat shrink tube 20 is shown by a virtual line for display). Then, heat is applied to the heat shrinkable tube 20. Then, the heat-shrinkable tube 20 shrinks into a shape along the outer contour of the portion (terminal 2 and electric wire W) housed inside. As a result, the electric wire 1A with a terminal shown in FIG. 1 is manufactured.

In this first embodiment, the tip height H1 of the core wire 11 protruding from the core wire crimping portion 4 is formed to be lower than the height H2 of the core wire 11 covered with the insulating coating 12. That is, the step at the tip of the core wire 11 with respect to the surface of the terminal 2 is lower than that in the case where only ultrasonic welding is performed without cutting. As a result, there is no part where a large shrinkage difference is formed when the heat-shrinkable tube 20 is heat-shrinked, and the tip of the heat-shrinkable tube 20 is in close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20). Closed), ensuring waterproofness.

Since the tip height H1 of the core wire 11 can be adjusted by the cutting position, the tip of the heat-shrinkable tube 20 can be surely brought into close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20 is closed). ..

Since the core wire 11 and the terminal 2 of the electric wire W are connected (fixed) by ultrasonic welding and the core wire crimping portion 4, compared with the case where only ultrasonic welding or only the core wire crimping portion 4 is connected (fixed). It is firmly connected (fixed). Even if water infiltrates into the heat-shrinkable tube 20 for some reason and a connection failure portion occurs due to corrosion, disconnection or the like can be prevented as much as possible by a strong connection. Further, in the first embodiment, since the entire exposed core wire 11 of the terminal portion has a reduced diameter, it is possible to secure a reliable connection (fixation) between the core wire 11 of the electric wire W and the terminal 2.

(Second Embodiment)
3 to 6 show a second embodiment of the present invention. The electric wire 1B with a terminal of the second embodiment differs only in the configuration of the exposed core wire 11 of the terminal portion. That is, in the second embodiment, the tip height H1 of the core wire 11 protruding from the core wire crimping portion 4 is removed by cutting the portion of the core wire 11 protruding from the core wire crimping portion 4 (not the entire core wire 11). Therefore, it is formed low. More specifically, the portion of the core wire 11 protruding from the core wire crimping portion 4 is formed on an inclined surface 11a that becomes lower toward the tip due to cutting.

Since the other configurations are the same as those of the first embodiment, the same components are designated by the same reference numerals as those of the first embodiment, and the description thereof will be omitted.

Next, the first to third manufacturing procedures of the electric wire 1B with terminals will be sequentially described.

First, the first manufacturing method will be described. As shown in FIG. 4A, in the electric wire W, the insulating coating 12 of the terminal portion is removed and the core wire 11 is exposed. The terminal portion of the electric wire W is placed on the base portion 3 of the terminal 2, and ultrasonic welding is performed between the core wire 11 and the terminal 2. With this, the core wire 11 and the base portion 3 of the terminal 2 are welded. In ultrasonic welding, a compressive force is applied to the core wire 11 and the core wire 11 is slightly melted, so that the height of the core wire 11 is slightly lowered.

Next, as shown in FIG. 4B, the upper portion on the tip end side of the exposed core wire 11 of the terminal portion is cut in a tapered shape. As a result, an inclined surface 11a that becomes lower toward the tip is formed at the tip of the exposed core wire 11 of the terminal portion. Next, as shown in FIG. 4C, the insulating coating 12 near the terminal portion of the electric wire W is crimped and crimped by the coating crimping portion 5, and the exposed core wire 11 of the terminal portion of the electric wire W is crimped to the core wire crimping portion 4. Cramping and crimping. Next, as shown in FIG. 4 (d), the heat-shrinkable tube 20 is inserted at a position that completely covers the exposed core wire 11 (in FIG. 4 (d), the accommodation portion in the heat-shrinkable tube 20 is clearly defined. The heat shrink tube 20 is shown by a virtual line for display). Then, heat is applied to the heat shrinkable tube 20. Then, the heat-shrinkable tube 20 shrinks into a shape along the outer contour of the portion (terminal 2 and electric wire W) housed inside. As a result, the electric wire 1B with a terminal shown in FIG. 2 is manufactured.

Next, the second manufacturing method will be described. As shown in FIG. 5, in the second manufacturing method, in comparison with the first manufacturing method, the electric wire W is first crimped (see FIG. 5B), and then the exposed core wire of the terminal portion is exposed. The difference is that the cutting step on the tip side of No. 11 (see FIG. 5C) is performed. Other than this, it is the same as the first manufacturing method, so duplicate description will be omitted.

Next, the third manufacturing method will be described. As shown in FIG. 6, in the third manufacturing method, in comparison with the first manufacturing method, first, a cutting step (see FIG. 6A) of the tip end side of the exposed core wire 11 of the terminal portion is performed. The difference is that an ultrasonic welding step (see FIG. 6B) is then performed. Other than this, it is the same as the first manufacturing method, so duplicate description will be omitted.

In this second embodiment, the tip height H1 of the core wire 11 protruding from the core wire crimping portion 4 is formed lower than the height H2 of the core wire 11 covered with the insulating coating 12. That is, the step at the tip of the core wire 11 with respect to the surface of the terminal 2 is lower than that in the case where only ultrasonic welding is performed without cutting. As a result, there is no part where a large shrinkage difference is formed when the heat-shrinkable tube 20 is heat-shrinked, and the tip of the heat-shrinkable tube 20 is in close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20). Closed), ensuring waterproofness.

Since the tip height H1 of the core wire 11 can be adjusted by the cutting position, the tip of the heat-shrinkable tube 20 can be surely brought into close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20 is closed). ..

Since the core wire 11 and the terminal 2 of the electric wire W are connected (fixed) by ultrasonic welding and the core wire crimping portion 4, compared with the case where only ultrasonic welding or only the core wire crimping portion 4 is connected (fixed). It is firmly connected (fixed).

(Third Embodiment)
7 and 8 show a third embodiment of the present invention. In the electric wire 1C with a terminal of the third embodiment, as in the second embodiment, the tip height H1 of the core wire 11 protruding from the core wire crimping portion 4 is such that the portion of the core wire 11 protruding from the core wire crimping portion 4 is cut. It is formed low by being removed, but the cutting method is different. That is, the portion of the core wire 11 protruding from the core wire crimping portion 4 is formed on the surface 11b where the entire upper portion of the core wire is one step lower by cutting.

Since the other configurations are the same as those of the first embodiment, the same components are designated by the same reference numerals as those of the first embodiment, and the description thereof will be omitted.

The manufacturing method of the electric wire 1C with a terminal of the third embodiment can be manufactured by substantially the same manufacturing method as that of the second embodiment except for the method of cutting the tip of the exposed core wire 11. For example, FIG. 8 shows a third manufacturing method (corresponding to FIG. 6). As shown in FIG. 8, the ultrasonic welding step between the core wire 11 and the terminal 2, the crimping step of the terminal 2, the cutting step of the tip end portion of the core wire 11, and the sealing step by the heat shrinkable tube 20 are performed in this order.

In the third embodiment, the tip height H1 of the core wire 11 protruding from the core wire crimping portion 4 is formed to be lower than the height H2 of the core wire 11 covered with the insulating coating 12. That is, the step at the tip of the core wire 11 with respect to the surface of the terminal 2 is lower than that in the case where only ultrasonic welding is performed without cutting. As a result, there is no part where a large shrinkage difference is formed when the heat-shrinkable tube 20 is heat-shrinked, and the tip of the heat-shrinkable tube 20 is in close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20). Closed), ensuring waterproofness.

Since the tip height H1 of the core wire 11 can be adjusted by the cutting position, the tip of the heat-shrinkable tube 20 can be surely brought into close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20 is closed). ..

Since the core wire 11 and the terminal 2 of the electric wire W are connected (fixed) by ultrasonic welding and the core wire crimping portion 4, compared with the case where only ultrasonic welding or only the core wire crimping portion 4 is connected (fixed). It is firmly connected (fixed).

(Fourth Embodiment)
9 to 11 show a fourth embodiment of the present invention. In the electric wire 1D with a terminal of the fourth embodiment, as compared with the first embodiment, only the exposed core wire 11 of the terminal portion is welded between the strands of the core wire 11 by ultrasonic welding, but the terminal portion The difference is that the exposed core wire 11 is not connected (fixed) to the base portion 3 of the terminal 2 by ultrasonic welding. The exposed core wire 11 of the terminal portion is connected (fixed) to the terminal 2 only by the core wire crimping portion 4.

Since the other configurations are the same as those of the first embodiment, the same components are designated by the same reference numerals as those of the first embodiment, and the description thereof will be omitted.

Next, the first and second manufacturing procedures of the electric wire 1D with terminals will be sequentially described.

First, the first manufacturing method will be described. As shown in FIG. 10A, in the electric wire W, the insulating coating 12 of the terminal portion is removed and the core wire 11 is exposed. Only the exposed core wire 11 of the terminal portion is ultrasonically welded. With this, the wires of the core wire 11 are welded together. In ultrasonic welding, a compressive force is applied to the core wire 11 and the core wire 11 is slightly melted, so that the height of the core wire 11 is slightly lowered.

Next, as shown in FIG. 10B, the insulating coating 12 near the terminal portion of the electric wire W is crimped and crimped by the coating crimping portion 5, and the exposed core wire 11 of the terminal portion of the electric wire W is crimped to the core wire crimping portion 4. Cramping and crimping.

Next, as shown in FIG. 10 (c), the upper portion on the tip end side of the exposed core wire 11 of the terminal portion is cut in a tapered shape. As a result, an inclined surface 11a that becomes lower toward the tip is formed at the tip of the exposed core wire 11 of the terminal portion.

Next, as shown in FIG. 10 (d), the heat-shrinkable tube 20 is inserted at a position that completely covers the exposed core wire 11 (in FIG. 10 (d), the accommodation portion in the heat-shrinkable tube 20 is clearly defined. The heat shrink tube 20 is shown by a virtual line for display). Then, heat is applied to the heat shrinkable tube 20. Then, the heat-shrinkable tube 20 shrinks into a shape along the outer contour of the portion (terminal 2 and electric wire W) housed inside. With this, the electric wire 1D with a terminal shown in FIG. 9 is manufactured.

Next, the second manufacturing method will be described. As shown in FIG. 11, in the second manufacturing method, in comparison with the first manufacturing method, a cutting step (see FIG. 11B) of the tip end side of the exposed core wire 11 of the terminal portion is first performed. The difference is that the crimping step of the electric wire W (see FIG. 11C) is then performed. Other than this, it is the same as the first manufacturing method, so duplicate description will be omitted.

In the fourth embodiment, the core wire 11 is covered with the insulating coating 12, the core wire 11 of the terminal portion is exposed from the insulating coating 12, and the exposed core wire 11 is ultrasonically welded to the electric wire W and the terminal portion. A terminal 2 having a core wire crimping portion 4 for crimping and connecting the exposed core wire 11 and a shrink tube 20 for sealing the exposed core wire 11 of the terminal portion and the core wire crimping portion 4 are provided, and the core wire crimping portion is provided. The terminal-equipped electric wire 1D is characterized in that the tip height of the core wire 11 protruding from 4 is formed lower than the height of the core wire 11 covered with the insulating coating 12.

In the fourth embodiment, the tip height H1 of the core wire 11 protruding from the core wire crimping portion 4 is formed to be lower than the height H2 of the core wire 11 covered with the insulating coating 12. That is, the step at the tip of the core wire 11 with respect to the surface of the terminal 2 is lower than that in the case where only ultrasonic welding is performed without cutting. As a result, there is no part where a large shrinkage difference is formed when the heat-shrinkable tube 20 is heat-shrinked, and the tip of the heat-shrinkable tube 20 is in close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20). Closed), ensuring waterproofness.

Since the tip height H1 of the core wire 11 can be adjusted by the cutting position, the tip of the heat-shrinkable tube 20 can be surely brought into close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20 is closed). ..

Since the exposed core wire 11 of the terminal portion is ultrasonically welded, it becomes easy to secure an electrical connection between the strands constituting the core wire 11. As a result, it is possible to reduce the electric resistance at the connection point between the electric wire W and the terminal 2.

(Fifth Embodiment)
FIG. 12 shows a fifth embodiment of the present invention. As shown in FIG. 12A, the electric wire 1E with a terminal of the fifth embodiment has the electric wire W whose core wire 11 is covered with the insulating coating 12 and the terminal connected to the electric wire W, as in the first embodiment. 2 and a heat-shrinkable tube (shrinkable tube) 20 for sealing the connection portion between the terminal 2 and the electric wire W are provided. The difference from the first embodiment is that the core wire 11 and the terminal 2 of the electric wire W are not ultrasonically welded but are connected only by crimping the core wire crimping portion 4.

As shown in FIG. 12B, the exposed core wire 11 of the terminal portion of the electric wire W has its entire upper portion removed by cutting.

Therefore, also in this fifth embodiment, the tip height H1 of the core wire 11 protruding from the core wire crimping portion 4 is formed lower than the height H2 of the core wire 11 covered with the insulating coating 12. That is, the step at the tip of the core wire 11 with respect to the surface of the terminal 2 is lower than that in the case where only ultrasonic welding is performed without cutting. As a result, there is no part where a large shrinkage difference is formed when the heat-shrinkable tube 20 is heat-shrinked, and the tip of the heat-shrinkable tube 20 is in close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20). Closed), ensuring waterproofness.

Since the tip height H1 of the core wire 11 can be adjusted by the cutting position, the tip of the heat-shrinkable tube 20 can be surely brought into close contact with the entire outer peripheral surface of the terminal 2 (so-called heat-shrinkable tube 20 is closed). ..

(Modification example, etc.)
In each embodiment, the electric wire W can be applied to an aluminum electric wire, a copper electric wire, a mixed electric wire of aluminum and copper, and the like. In particular, when the electric wire W is an aluminum electric wire or a mixed electric wire of aluminum and copper, each of the embodiments is effective because corrosion by water is likely to occur in the electric wires 1A to 1D with terminals.

In each embodiment, the heat-shrinkable tube 20 has a tubular shape in which the tip side is gradually reduced in diameter as shown in FIG. 2D and the like before shrinking due to heat. The heat shrinkable tube 20 may have a cylindrical shape having the same diameter over the entire area. However, since the amount of heat shrinkage is smaller when the shape of each embodiment is used, the adhesion to the terminal 2 can be improved.

In each embodiment, the heat shrink tube 20 is used as the shrink tube, but the shrink tube may be a tube that shrinks by physical or scientific action.

In each embodiment, when the ultrasonic welding step is performed, the coating crimping portion 5 of the terminal 2 may be crimped to the insulating coating 12 of the electric wire W.
