Description

{Car glass terminal}

The present invention relates to a terminal for an automobile glass, and more particularly to a terminal for an automobile glass in which at least one slot formed in a metal pattern formed on an automobile glass surface is soldered and electrically connected.

Automobile safety glass consists of windshield, rear glass and side glass and is made of tempered glass or laminated glass to protect the safety of the driver and passengers.

On the glass surface, a silver paste is used as a material to form a hot line pattern in micrometers by screen printing, and the hot line pattern is mainly formed on the rear glass. The terminal is soldered onto the glass on which the hot wire pattern is formed and bonded to the glass.

The terminal is connected to the heating wire to be used as a connection part for heating the heating wire of the glass, or as a connection part for receiving the radio wave connected to the antenna, and the power wire and the antenna wires are connected to this terminal.

In the conventional soldering method, after the terminal is fixed at the attachment position of the hot wire pattern located on the inner surface of the glass, the operator manually melts the solder by using the soldering iron, the molten solder flows between the terminal and the glass, Terminal is attached to the glass.

Such conventional manual soldering has a problem in that it increases the working time to lower the workability and uses an excessive amount of solder to achieve a desired adhesive force.

In addition, since the soldering iron is directly brought into contact with the glass in the state where the terminals are attached to the glass, a thermal shock is applied to the base metal (terminal, glass). In automobile glass, tempered glass is applied by heat treatment, and the nature of the base material is deformed due to thermal shock caused by soldering during soldering, which causes quality problems.

In addition, variations in the amount of solder between the products and the contact time of the base material in the soldering iron vary depending on the skill level of the worker, and it is difficult to ensure the consistent quality of the product.

The terminal for an automobile glass according to the present invention has the following purpose.

(1) A terminal for an automobile glass capable of remarkably improving the workability of soldering by increasing the melting rate of the solder.

(2) A terminal for an automobile glass which can increase the melting speed of the solder and achieve a desired adhesive force even with a small amount of solder, thereby reducing the cost.

(3) A direct or indirect automatic soldering process is applied to provide terminals for automobile glass that can improve productivity.

(4) A terminal for an automobile glass that can prevent solder from being detached from a terminal after pre-soldering.

(5) A terminal for an automobile glass capable of increasing a bonding force between a terminal and a glass by increasing a heating area of the solder.

(6) A terminal for an automobile glass capable of reducing the occurrence of thermal stress due to a difference in thermal expansion coefficient between a glass and a metal located between two solder-attached portions of a metal pattern of a glass.

(7) Since the melted solder flows quickly through the slot formed in the attachment portion, and joins between the metal pattern and the terminal, the heating time of the glass is reduced, and the amount of thermal shock applied to the glass can be reduced.

(8) By increasing the heating area of the solder, the melting rate of the solder is increased, thereby minimizing the stress caused by the difference in thermal expansion between the terminal and the glass, thereby preventing the decrease in the strength of the glass, Thereby providing a terminal for an automobile glass which can reduce the possibility of breakage.

(9) By forming a slot in the attachment portion, the solder contact area of the solder bonded portion with the metal pattern on the glass is increased, and the bonding force of the terminal can be increased.

The objects of the present invention are not limited to those mentioned above, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

A terminal for an automobile glass according to an embodiment of the present invention is attached to and electrically connected to a hot wire or a metal pattern of an antenna attached to an automobile glass, And solder pre-soldered to the mounting portion, wherein the solder is melted to fix the mounting portion on the metal pattern.

The slot includes a through hole formed in an inner side of the attachment portion and passing through an upper surface and a lower surface of the attachment portion; And a through extension extending from an upper surface and a lower surface of the attachment portion to an outer side of the attachment portion from the through hole.

It is preferable that the through hole has a circular or polygonal hole shape.

And the slot preferably includes a through extension extending through the upper surface and the lower surface of the attachment portion and extending from the inside of the attachment portion to the outside of the attachment portion.

Preferably, the solder is pre-soldered to the lower surface of the attachment portion and the inside of the slot.

The terminal for an automobile glass according to the present invention provides the following effects.

(1) The melting speed of the solder is increased, and the workability of the soldering is remarkably improved.

(2) By increasing the melting rate of the solder, it is possible to achieve a desired adhesive force even with a small amount of solder, thereby reducing the cost.

(3) Direct or indirect automatic soldering process is applied to improve productivity.

(4) Prevent solder from detaching from terminal after pre-soldering.

(5) As the heating area of the solder is increased, the bonding force between the terminal and the glass is increased.

(6) Reduces the thermal stress caused by the difference in thermal expansion coefficient between the glass and the metal located between the two solder-attached portions of the metal pattern of the glass.

 (7) Since the molten solder rapidly flows through the slot formed in the attachment portion and joins between the metal pattern and the terminal, the heating time of the glass is reduced, and the amount of thermal shock applied to the glass is reduced.

(8) By increasing the heating area of the solder, the melting rate of the solder is increased, thereby minimizing the stress caused by the difference in thermal expansion between the terminal and the glass, thereby preventing the decrease in the strength of the glass, Thereby reducing the possibility of breakage.

(9) By forming a slot in the attaching portion, the solder contacting area of the solder bonded portion with the metal pattern on the glass is increased, and the bonding force of the terminal is increased.

The effects of the present invention are not limited to those mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the following description.

1 is a view showing a terminal for an automobile glass according to a preferred embodiment of the present invention.
2 is a view showing a modified example of a slot of an automotive glass terminal according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a view showing a terminal for an automobile glass according to a preferred embodiment of the present invention.

A terminal 100 for an automobile glass according to an embodiment of the present invention is a metal terminal for an automobile glass which is attached to and electrically connected to a hot wire or a metal pattern of an antenna attached to an automobile glass. The terminal 100 includes an attachment portion 110 and a solder 130.

The attachment portion 110 is formed on both sides of the terminal 100, and preferably has a plate shape. At least one slot 120 is formed in the attachment portion 110.

The slot 120 penetrates the upper surface and the lower surface of the attaching portion 110 and has a through hole 121 formed in the inside of the attaching portion 110 and a through hole 121 passing through the upper and lower surfaces of the attaching portion 110. [ And a penetration extension portion 122 extending from the attachment portion 110 to the outside of the attachment portion 110. The inner through hole 121 may have various shapes such as a circular shape, a square shape, and a polygonal shape. In addition, the slot 120 may include only the penetration extending portion 122 without the through hole 121.

2 is a view showing a modified example of a slot of an automotive glass terminal according to a preferred embodiment of the present invention.

2 (a) and 2 (b) show the shape of a slot in which the through extension extends from the circular through-hole. FIG. 2 (c) shows the shape of the slot in which the through- 2 (d) shows the shape of a slot in which a through extension extends from a rectangular through hole, and FIG. 2 (e) shows the shape of a slot in which only a through extension is present without a through hole.

Solder 130 is pre-soldered to fill the interior of slot 120 as well as being attached to the lower surface of attachment 110. The area of contact of the pre-soldered solder 130 with the mount 110 due to the slot 120 is increased to prevent the solder 130 from being detached from the mount 110 after pre-soldering.

The pre-soldered solder 130 is brought into direct contact with the heating part through the slot 120 when the upper surface of the attachment part 110 is heated by the heating part (for example, the iron) The melted solder 130 flows between the mounting portion 110 and the glass to bond the mounting portion 110 and the glass. The area of contact between the solder 130 and the attaching portion 110 is increased as compared with the conventional case, so that the bonding force between the attaching portion 110 and the glass is increased.

The metal terminal 100 and the glass have different thermal expansion coefficients and the glass and metal terminals 100 positioned between the attachment portions 110 when heating the attachment portions 110 located on both sides of the terminal 100 The thermal stress due to the difference in the thermal expansion coefficient occurs. When the melting time of the solder 130 is shortened, the generation of such thermal stress can be suppressed.

In addition, the terminal 100 according to an embodiment of the present invention can increase the melting speed of the solder 130, thereby achieving a desired adhesive force even with a small amount of solder, thereby reducing the cost. In the case of using the terminal 100 according to an embodiment of the present invention, the amount of solder used is reduced by about 60% compared with the conventional one, and the cost saving effect is reduced by about 50% as compared with the related art. Particularly, since lead-free solders contain a large amount of expensive indium, the cost reduction effect of the use of the lead-free solder is more excellent.

In addition, the terminal 100 according to an embodiment of the present invention can be applied to an automatic soldering process by induction heating because the melting area of the solder is increased and the melting rate is short. Thus, the productivity is remarkably improved .

Among the effects of the present invention, the experimental results relating to the improvement of the adhesive strength and the reduction of the solder amount are as follows.

The experimental example and the comparative example are terminals having the same shape, and only the shape of the slot is different. The experimental example is a terminal having a slot of the shape shown in Fig. 2 (a) of the present invention. Experiments were conducted on eight samples. The comparative example is a conventional terminal having an attachment part shape in which only through holes exist, Experiments were performed on 8 samples.

The initial adhesive strength test and the adhesive strength test under high temperature and high humidity conditions were carried out. The amount of solder used is expressed in x g, and 3x means that solder is used three times as much as x.

As can be seen from Table 1, the experimental example shows better adhesion even when the solder amount is reduced by about 1/3 as compared with the comparative example. As can be seen from Table 2, it can be confirmed that the experimental example maintains an excellent adhesive force as compared with the comparative example in which the adhesive strength of the terminals remarkably decreases in the state of high temperature and high humidity.

While the present invention has been described in connection with certain exemplary embodiments, it will be understood by those skilled in the art that various changes may be made without departing from the scope of the present invention.
