Description

[Detailed description of the invention] [Industrial application field] The present invention is a defogger terminal for vehicles, particularly for connecting an electric heating pattern provided on a vehicle windshield and a power supply wire provided on the vehicle body. This relates to a defogger terminal for vehicles.

[Conventional technology]

As a device to quickly remove frost adhering to a vehicle's windshield, especially the side and rear windshields, a predetermined current is supplied to the defogger heating wire affixed to the windshield surface, and the defrost is removed by resistive heat generation. The defotsuga heat wire that performs this is well known.

This type of defogger heating wire requires a connection structure that connects the electric heating pattern affixed to the windshield surface in advance and the power supply wire provided on the vehicle body side quickly and reliably during assembly, and that does not cause disconnection during use. Conventionally, the connection between the two has been made using a defogger terminal.

However, conventional terminals usually
The removable connector is formed as a pair of male and female terminals, i.e. the male terminal on one side is usually soldered to the heating pattern on the windshield surface, and the female terminal is attached to the power supply wire on the vehicle side. Both terminals can be easily attached and detached.

For example, as shown in FIG. 12, the lower surfaces of the soldered portions 16 and 18 of the male terminal 14 are fixed on the electric heating pattern 12 attached to the surface of the windshield 10, and the male terminal 1
The other end of 4 is bent upward to form a male connection. A female connector is fixed to the tip of the power supply wire 26, the other end of which is connected to the vehicle body side, and is detachable from the male contact portion of the male terminal 14.

On the other hand, unlike such a connector-type connection device, a connection structure in which a power supply wire is directly soldered to an electric heating pattern is also known.

However, in this direct connection structure, soldering between the power supply wire made of stranded wires and the electrode pattern made of thin film electrodes is not always performed well, and the mechanical strength or electrical connection state may be poor. There was a fear that something would happen.

[Problem that the invention attempts to solve]

Therefore, conventionally, a connection structure using a terminal that makes two-dimensional contact with the electric heating pattern to establish a mechanically or electrically reliable connection is preferable, but the conventional male terminal as shown in FIG. According to a connector using a pair of terminals, depending on the type of vehicle or the structure around the windshield, it may be difficult to attach or detach the detachable connector 27, or it may be difficult to connect the terminals once removed. This also creates a difficult structure, which limits the connection area of the terminal and creates an unsightly terminal arrangement in the passenger compartment.Also, a large space is required for the connector housing, so the height of the terminal is limited. There was also the problem that it became expensive and the possibility of deformation increased.

The object of the present invention is to provide a defogger terminal for a vehicle to solve the above-mentioned problems.

[Means for solving problems]

The vehicle defogger terminal according to the present invention includes a soldering part that is soldered and connected to the electric heating pattern provided on the windshield surface of the vehicle in surface contact, and an electric wire caulking part to which the power supply wire is caulked and fixed. Either the soldering part or the wire crimping part is offset from the other so that the soldering part, the wire crimping part, and the wire path are at a position where they are not heavy when viewed from the windshield surface.

[Effect]

The above-mentioned vehicle defogger terminal has a soldered part and is fixed by soldering onto the electric heating pattern.
Connection with the power supply wire is made by caulking one end of the power supply wire at the wire crimping portion. Therefore, there is no need to attach or detach the connector, which is a difficult task when connecting by connecting a connector using a pair of male and female terminals.
There is no need to arrange the terminal in consideration of ease of attachment/detachment work, and there is no risk of spoiling the aesthetics of the interior of the vehicle. Further, since the soldering part and the wire crimping part are arranged offset, there is no problem in the soldering work of the soldering part, and workability during installation is ensured.

〔Example〕

Example of Basic Configuration FIG. 1 is a side view showing an example of the basic configuration of the present invention.

In the figure, an electric heating pattern 12 is pasted on the windshield 10 of the vehicle. One end of a vehicle defogger terminal 14 according to the present invention is soldered and fixed onto this electrothermal pattern 12 with soldering portions 16 and 18. A power supply wire 26 is caulked and connected to the other end of this terminal. A wire crimping portion 24 is formed that is bent upward, and the wire crimping portion 24 has an appropriate slope so that the power feeding wire 26 can be easily crimped. Although this figure shows the state in which the electric wire 26 is caulked, the electric wire 26 is secured by caulking the sheathing part of the electric wire 26 to the upper end of the caulking surface 28, as shown in FIG. A pair of first caulking protrusions 30 are provided to securely fix the wire 26, and a pair of first caulking convex portions 30 are provided below the first caulking convex portions 30 to secure an electrical connection by caulking the uncoated tip of the electric wire 26. A second caulking convex portion 32 is provided.

In this basic configuration example, the power supply wire 26 is caulked during the vehicle body assembly process, so there is no need to connect the connector after assembly, which is difficult to do, and the connection strength is strong, so the power supply wire 26
However, it has the advantage that it does not easily come off from the caulked portion 24.

First Embodiment FIG. 3 is a plan view showing a first embodiment of this invention, in which the same elements as those in the basic configuration are given the same reference numerals. The defogger terminal shown in FIG. 3 is designed to place the caulked part 24 and the caulked electric wire 26 in a position where they will not interfere with the soldering work of the soldering parts 16 and 18. The attachment portion 18 is offset from the route of the power supply wire 26. That is, when bending and forming the main body of the defogger terminal 14 of the present invention, the length of the portion 34 formed by folding back the standing portion connected to the soldering portion 16 is such that the soldering portion 18 is offset from the electric wire 26. The length is such that it can be placed in any position. As a result, the soldering part 18 has an offset distance of ₁ with respect to the electric wire 26, which improves the workability of the soldering operation and prevents heat damage and damage to the electric wire 26 during the soldering operation. be able to.

Next, in a modification of the first embodiment shown in FIG.
6 and 18 so as to be offset from each other. Therefore, soldering part 1
6 and 18 on the same line, solder part 1.
Since an offset distance can be obtained between the electric wire 26 and the electric wire 26, the electric heating pattern can be formed without having an irregular shape as in the embodiment shown in FIG.

Second Embodiment FIG. 5 is a perspective view showing a second embodiment of the present invention. In this embodiment, two pairs of caulking convex portions 30, 3
A caulking surface 28 having a diameter of 2 is formed substantially perpendicular to the windshield surface, and the wire route of the caulked electric wire 26 does not overlap with the soldering portion 18 in the direction perpendicular to the windshield surface. That is, as shown in the plan view of the defogger terminal of this embodiment in FIG.
is located on a line connecting one edge 16a and 18a of each of the soldered portions 16 and 18, when viewed from a direction perpendicular to the windshield surface. It goes without saying that the caulking surface 28 can be formed to protrude further away from the soldering surface than on this line.

In this embodiment, it is possible to easily obtain a structure in which the route of the crimped electric wire 26 and the soldered portion 18 do not overlap in the direction perpendicular to the windshield surface. In addition, as shown in the side view of the defogger terminal according to the embodiment in FIG. Terminal height ₂ can be made low. Thereby, deformation of the wire crimped portion can be prevented.

Furthermore, FIG. 8 is a perspective view showing another modification of the second embodiment of the present invention. In this example, caulking surface 2
8 is formed diagonally with respect to the terminal body. That is, as shown in the plan view of the defogger terminal according to the present example in FIG.
Corner 1 of the soldering part 18 diagonally opposite from
A caulking surface 28 is provided across 8b. In this example, since the tensile force of the electric wire 26 (in the direction of arrow A) is applied diagonally to the soldering parts 16 and 18,
The peel strength of the soldered parts 16 and 18 can be increased. Also, the electric wire 2 for the soldering part 18
The offset distance of 6 can be made larger,
Heat damage and damage to the electric wire 26 can be more effectively prevented.

FIGS. 10 and 11 are diagrams showing other modifications of the second embodiment of the present invention.

In the example shown in FIG. 10, the angle 38 formed by the crimping surface 28 and the upright portion 36 continuous with the soldering portion in the terminal body is formed to be a right angle.
According to this example, there is an advantage that caulking work of the electric wire 26 is easy to perform.

The example shown in FIG. 11 is the same as the example shown in FIG. 9, in which the upright portion in contact with the soldering portion is doubled by folding back. In this example, the peel strength of the soldered portion is increased by preventing deformation of the terminal itself. Note that the double structure of the upright portion 36 according to this example can also be applied to the modification shown in FIG. 10.

[Effect of idea]

The vehicle differential terminal according to the present invention is
The soldered part is fixed by soldering on the electric heating pattern affixed to the windshield surface, and connection with the power supply wire is made by crimping the power supply wire that supplies current to the defogger heating wire to the wire crimping part. Therefore, unlike the case where the power supply wire is connected through a connector using a pair of male and female terminals, the wire crimping work in the vehicle differential terminal according to the present invention is performed during the vehicle body assembly process. Because the bonding strength is strong, there is no need to attach or detach the connector, which can be difficult depending on the vehicle model or the structure around the windshield surface, and also eliminates the need for space in the connector housing. Therefore, the height of the terminal can be lowered and deformation of the terminal can be prevented. Furthermore, since the soldering part and the wire crimping part are arranged offset, workability during soldering can be ensured, and assembly and installation can be carried out efficiently.
