Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a terminal bonded to an automobile window glass and a method for attaching the terminal.
[0002]
[Prior art]
A rear window glass (hereinafter referred to as rear glass) for automobiles is provided with a conductive pattern obtained by screen-printing silver paste on the glass surface on the vehicle interior side and then firing the glass to prevent fogging of the window glass. This conductor pattern is composed of a heat wire for heating the window glass and a bus bar for supplying a current to the heat wire. Some of the conductor patterns include antenna wires, and others include only antenna wires and bus bars. Defrosting of the window glass is performed by supplying electric current to the hot wire. A plurality of the heat rays are arranged in parallel on the window glass, and both ends thereof are connected to each other by a bus bar made of the same silver paste. A terminal is bonded to the bus bar for power supply. The terminal is connected to a power source such as a battery via a lead wire. In addition, antenna terminals and the like are bonded to the bus bar.
[0003]
The conventional terminal includes a base that is bonded to the bus bar by soldering, and a terminal that is a connecting piece for connecting to the base and an external connection coupler provided at the end of the lead wire. When this coupler is inserted into a terminal (connecting piece) of a terminal fixed to a window glass, a strong insertion force acts on the terminal, so that the terminal may be peeled off if the base is not sufficiently soldered. For this reason, a certain amount of adhesive strength is required between the bus bar and the terminal. In order to improve such adhesive strength, for example, Patent Documents 1 to 3 describe terminals that take adhesive strength into consideration.

[Problems to be solved by the invention]
However, since the terminal has a variety of shapes, it is difficult to automate bonding to the window glass by a robot or the like, and the bonding is left to human hands. That is, the base of the terminal has a substantially constant shape, but the size of the terminal (connection piece) integrated therewith varies in size, shape, orientation, etc. depending on the vehicle type or application. For this reason, it is necessary to prepare a small number of various types of terminals, change the terminals for each vehicle type and use, and perform solder bonding, and solder bonding is performed manually by workers.
[0006]
For this reason, even if it is devised to increase the adhesive strength as in Patent Documents 1 to 3, the skill of the person performing soldering is necessary to obtain a stable adhesive strength, and the adhesive state varies from product to product. Skill is also necessary to obtain stable and reliable adhesive strength. In addition, manual attachment of terminals takes time, and the workability is poor and there is a problem in productivity. In addition, the terminals to be bonded must be changed for each vehicle type and application, which increases man-hours for parts management, work management, and quality control.
[0007]
The present invention is based on the above-described prior art, and can be automatically attached to the window glass by solder bonding regardless of the shape of the terminal terminal. Highly reliable solder bonding with high reliability and sufficient terminal coupling strength, and can easily cope with vehicle type changes and terminal changes, and component management and work management in the solder bonding process The purpose is to provide automotive window glass terminals that can be easily controlled.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a conductor pattern is formed on the surface of an automotive window glass, and is a terminal for electrical connection bonded to the conductor pattern by solder, and is soldered to the conductor pattern. And a terminal for connecting to a coupler for external connection, the terminal being separate from the base, and the terminal being coupled to the base via a connecting member Provide window glass terminals.
[0009]
According to this configuration, the terminal is coupled to the base via the connecting member, and the base and the terminal are separate structures. Therefore, a certain standard shape base and various types of terminals having different shapes can be provided. A combination of different types of terminals can be formed. Therefore, even if it is a different kind of terminal, only the base of a fixed shape is first bonded to the window glass, and then the terminals are joined together to unify the soldering operation of the different terminals. For this reason, since the bonding operation of the base can be performed in a fixed pattern, it is possible to automate the bonding of the base to the window glass, the mounting time is quick, and the workability is improved.
[0010]
In this case, the terminal and the base are separate from each other and are coupled to each other via a connecting member provided on either the terminal or the base. That is, the connecting member may be integrated with the terminal and may be separate from the base, or conversely, may be integrated with the base and separate from the terminal, or may be separate from the terminal and the base. . The connecting member refers to a member indispensable for electrically and mechanically coupling the terminal and the base.
[0011]
In addition, automation eliminates the need for soldering skills and skill, eliminates variations in the adhesion state due to differences in worker skills, and makes it possible to always attach highly reliable terminals.
[0012]
Further, since different types of terminals can be bonded to the window glass using a common base, it is not necessary to distinguish the bonded components, and the component management, product management, and quality management of the solder bonding process are simplified.
[0013]
In addition, when the terminal and base are detachable, if the terminal needs to be repaired or replaced for maintenance, etc., only the terminal can be removed. And usability is improved.
[0014]
In a preferred configuration example, the connecting member is integral with the terminal, the connecting member has a locking piece, and the locking piece is inserted into an opening of the base so that the terminal becomes the base. It is characterized by combining.
[0015]
According to this configuration, the connecting member is integral with the terminal, and the locking piece of the connecting member is inserted from the opening of the base and locked to the base to securely connect the terminal and the base. Further, the handling of the terminal is improved by integrating the connecting member with the terminal.

In a preferred configuration example, the connecting member is integral with the terminal, and the base is continuous with the pedestal portion soldered to the conductor pattern, a rising portion continuous with the pedestal portion, and the rising portion. The connecting member has a locking piece parallel to the top surface having a protrusion at the tip, the base has an opening at the rising portion, and the locking piece is inserted into the opening. Then, the protrusion is elastically locked and coupled to the base side.
[0017]
According to this configuration, the connecting member is integral with the terminal, and the locking piece of the connecting member integrated with the terminal is securely locked and fixed to the base. The terminal does not come off the base when installing the coupler. Since the locking piece is inserted from the side to the lower side of the upper surface portion of the base through the opening of the rising portion of the base, the coupling state can be reliably maintained when the terminal is pulled upward.
[0018]
In a preferred configuration example, the connecting member is integral with the terminal, and the base is continuous with the pedestal portion soldered to the conductor pattern, a rising portion continuous with the pedestal portion, and the rising portion. The connecting member has a locking piece protruding downward with respect to the pair of C-shaped upper surface portions and a positioning convex portion, and the base is connected to the terminal on the upper surface portion. An opening for inserting the locking piece having a longitudinal direction perpendicular to a direction in which the locking piece spreading in the shape of a letter C is joined and a hole or a recess into which the convex part is fitted. It is said.
[0019]
According to this configuration, the connecting member is integral with the terminal, and the locking piece and the convex portion of the connecting member integrated with the terminal are securely locked and fitted to the base to be fixed. For this reason, the terminal does not come off the base when a coupler for external connection is attached to the terminal. In this case, the locking piece is inserted through the opening on the upper surface portion of the base and rotated 90 ° from above, so that the work becomes easy and can be easily combined.
[0020]
In a preferred configuration example, the connecting member is integral with the terminal, and the base is continuous with the pedestal portion soldered to the conductor pattern, a rising portion continuous with the pedestal portion, and the rising portion. The connecting member slides on the upper surface portion of the base during assembly and is held and held on the upper surface portion, and the connecting member is used to prevent the protruding member from protruding downward. The base has an opening for locking the claw piece on the upper surface thereof, and side edges on both sides of the connecting member are in sliding contact with each other at the time of assembly to guide the connecting member. It is characterized by having side walls inclined inward so as to be brought into pressure contact with the upper surface of each side edge.
[0021]
According to this configuration, since the claw piece is securely locked and fixed to the opening of the upper surface portion of the base, the terminal is not detached from the base when the external connection coupler is attached to the terminal. In addition, since the inclined side walls on both sides of the upper surface of the base are in pressure contact with the connecting member to bring the connecting member into close contact with the upper surface, resistance loss when electricity is passed through the terminals is reduced, and power loss is reduced and power is efficiently supplied. can do.
[0022]
In another preferred configuration example, the terminal is separate from the coupling member and is connected to the coupling member via a lead wire.
[0023]
According to this configuration, the connecting member is separate from the base, and is also separate from the terminal. Since the terminal can connect the terminal and the coupler for external connection at a position away from the base via the lead wire, the force at the time of connection does not act on the base. Therefore, the adhesive strength between the base and the bus bar and the coupling strength between the connecting member and the base are ensured stably.
[0024]
In a preferred configuration example, the connecting member is separate from the terminal, the connecting member has a locking piece, and the terminal is made into a base by inserting the locking piece into an opening of the base. It is characterized by being coupled to.
[0025]
According to this configuration, the connecting member is separate from the terminal, and the locking piece of the connecting member is inserted from the opening of the base and locked to the base to securely connect the connecting member and the base. A terminal is electrically connected to the connecting member via a lead wire.
[0026]
In the present invention, the base is solder-bonded on the conductor pattern, and then the connecting member is inserted into the opening of the base to couple the connecting member and the base. Provided is a method of attaching a window glass terminal.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention.
FIG. 1 is a schematic view of a window glass to which a terminal of an automotive window glass according to the present invention is bonded.
[0029]
A plurality of heat wires 2 for preventing fogging are arranged in parallel on the rear glass 1 of the automobile. Each hot wire 2 is connected by a bus bar 3 at both left and right ends. The hot wire 2 and the bus bar 3 are film-like conductor patterns obtained by screen-printing silver paste on the rear glass 1 and sintering at around 600 ° C. to 700 ° C. A terminal 4 is soldered on the bus bar 3. A coupler, which will be described later, is connected to the terminal 4 and connected to a battery via a lead wire. When necessary, a current is supplied to the heat wire 2 and the rear glass 1 is defrosted.
[0030]
In addition, although the present Example demonstrates the power supply terminal of the rear glass of a motor vehicle, the terminal of the window glass for motor vehicles concerning this invention can be used also as a power supply terminal of the antenna terminal attached to a side glass, or the hot wire for snow melting attached to a windshield. It is.

FIG. 2 is a schematic view showing a base of a terminal of an automobile window glass according to the present invention, FIG. 3 is a schematic view of a terminal and a connecting member, and FIG. 4 is a schematic view when the base and the terminal are combined.
2A is a side view of the base mounted state, FIG. 2B is a top view of the base, FIG. 2C is an AA view of (B), and FIG. 2D is a perspective view of the base.
[0032]
As shown in FIG. 2A, the base 5 is bonded onto the bus bar 3 of the rear glass 1 via solder 6. The adhesive strength between the base 5 and the bus bar 3 is equal to or higher than a certain strength (for example, 78.4 N), and is securely fixed by the solder 6. The base 5 is generally made of copper or brass, and some are plated with tin to prevent oxidation. The base 5 includes a pedestal 5c soldered to the bus bar 3, a rising portion 5b continuous with the pedestal 5c, and an upper surface 5a continuous with the rising 5b. It has a stop holding part 7. The base 5 is formed by, for example, sheet metal punching and press bending. Openings 8 are formed in the rising portions 5b on both sides of the upper surface portion 5a. A locking piece of a connecting member integrated with a terminal to be described later is inserted from the opening 8 of one rising portion 5b. This opening 8 is not only for the insertion of the locking piece, but also by providing this opening 8, the base becomes a flexible structure, and the thermal stress based on the difference in thermal expansion coefficient between the glass and the base during soldering is released. By absorbing the metal expansion and contraction, a stable adhesive strength can be secured. In addition, as shown to (E), it is good also as a cantilever structure by providing the rising part 5b only in the one side of the upper surface part 5a.
[0033]
3A is a side view of the terminal and the connecting member, FIG. 3B is a bottom view thereof, FIG. 3C is a BB view of FIG. 3B, and FIG. As shown in the figure, the terminal 9 is integral with the connecting member 19 and is integrally formed, for example, by sheet metal punching and press bending. The terminal 9 is generally made of copper or brass, and some of them are plated with tin to prevent oxidation. The connecting member 19 has a pair of locking pieces 10 that are substantially parallel (or are gradually spaced toward the tip). A protrusion 11 is provided at the tip of the locking piece 10. The connecting member 19 integral with the terminal 9 is inserted into the base 5 shown in FIG. 2 to connect the base 5 and the terminal 9 to form the terminal 4 (FIG. 1).
[0034]
As shown in FIG. 4, when forming the terminal 4 according to the present invention, the locking piece of the connecting member 19 from the opening 8 provided in the rising portion 5 b of the base 5 bonded to the bus bar 3 of the rear glass 1 via the solder 6. 10 is inserted. While the two locking pieces 10 are elastically deformed inward, the tip protrusion 11 passes through the locking piece holding part 7, and the protrusion 11 is hooked and held by the end of the locking piece holding part 7. That is, when the locking piece 10 passes through the locking piece holding portion 7 of the base 5, the protrusions 11 at the tips of the two locking pieces 10 come into contact with the side walls of the locking piece holding portion 7, so that they face inward. When the stress acts, the projection 11 opens when it passes through the locking piece holding portion 7, and both are elastically locked and fixedly held. In this case, the pair of locking pieces 10 have a larger elastic force when they are inserted when the distance between the distal ends is somewhat wider than when they are completely parallel, so that the locking pieces 10 can be securely and elastically locked. can do. The coupler 13 at the end of the lead wire 12 connected to the battery (not shown) is fitted into the terminal 9 of the terminal 4 formed in this way, and power is supplied to the terminal 4 when necessary.
[0035]
In this way, the connecting member 19 can be reliably locked and held with respect to the base 5. Thereby, the connecting member 19 is not detached from the base 5 due to the insertion force generated when the coupler 13 is attached to the terminal 9. If the terminal 9 is to be replaced, the terminal 9 can be removed and replaced, so that it can be replaced with a new terminal or the like without requiring soldering or the like. In addition, in order to avoid unnecessary contact with the bus bar 3, it is desirable that the lower surface of the locking piece holding portion 7 is provided with a space from the bus bar 3.
[0036]
FIG. 5 is a schematic view of an example in which the shape of the terminal is changed.
Since the type of coupler and the direction in which the coupler is inserted are determined depending on the type of vehicle and the application of the terminal, the coupler 13 is inserted when the coupler 13 is inserted from the upper side of the terminal as shown in (A) or as shown in (B). There are cases where the coupler 13 is placed vertically and inserted from the side, and the variations thereof exceed 100. In the present invention, since the terminal and base of the terminal are separate bodies, the terminal 9 can be prepared in the same number of variations, and the base 5 can have the same shape. Therefore, all the operations of bonding the base 5 to the rear glass 1 can be performed in the same operation process, and can be automated by a robot or the like. This simplifies the work and enables quick and reliable mounting.

The terminal 9 of this embodiment is integral with the connecting member 19, and has a convex portion 16 and a locking piece 17 on the lower side of the connecting member 19. The locking piece 17 is formed so as to be opposed in a letter C shape whose lower side extends outward. Moreover, as shown to (E), the latching piece 17 may be pressed from a back surface, and a root may be protruded.
[0040]
When the base 5 and the terminal 9 of this embodiment are joined, as shown in FIG. 8A, the terminal 9 and the base 5 are orthogonally spread at the tip of the locking piece 17 in a state where the direction of the terminal 9 and the direction of the base 5 are orthogonal to each other. The inserted portion is inserted into the opening 15 of the base 5. Thereafter, as shown in (B), the terminal 9 is rotated by 90 °, and the convex portion 16 is fitted into the hole 14. As a result, the terminal 9 is positioned with respect to the base, and the expanding portion below the locking piece 17 is caught by the narrow portion of the opening 15, so that the connecting member 19 does not come off the base 5. Therefore, when the coupler is attached to the terminal 9, the terminal 9 is not detached, and the convex portion 16 and the hole 14 are fitted, so that the terminal 9 and the base 5 are stably and reliably maintained in a coupled state.
[0041]
If the terminal 9 is to be replaced, the terminal 9 can be removed and replaced, so that it can be replaced with a new terminal or the like without requiring soldering or the like.
[0042]

The base 5 of the present embodiment has an opening 20 at substantially the center of the upper surface portion 5a and side walls 21 that protrude inwardly on both sides of the upper surface portion. A terminal connecting member is inserted between the inclined side walls 21 as described later. Other configurations, the mounting method to the bus bar 3, etc. are the same as those of the base of FIG.

Thereafter, the claw piece 22 is locked to the opening 20 and the terminal 9 is coupled to the base 5. The connecting member 19 is subjected to a stress that tends to spread outward, but the side walls 21 on both sides inclined inwardly act on the side edges on both sides of the connecting member 19 obliquely from above, and a downward force acts. The member 19 and the upper surface portion 5a are brought into close contact with each other, so that the energization effect at the time of supplying power to the terminal is improved.

A piece 24 is formed. Both the locking pieces 10 may be formed so that the width H between the outsides is widened so that the front end side is wider (the front end is narrowed for insertion guide). Thereby, at the time of insertion into the base, it is elastically pressed against the side wall 21 as in the example of FIG. Further, the claw piece 24 is caught in the opening 20 and the base 5 and the terminal 9 are coupled. As in the example of FIG. 3, the protruding piece 23 can be omitted by providing the locking projection 11 and hooking it on the front end of the side wall 21 to prevent it from coming off.

The terminal 9 is connected to a coupler 13 provided at the end of a lead wire 12 connected to a battery (not shown), and power is supplied to the terminal 4 when necessary. Thereby, since the force at the time of connecting the coupler 13 is not transmitted to the base 5, the influence on the adhesive strength of the base 5 by the coupler connection is avoided. The coupling of the connecting member 19 and the base 5 is the same as that of FIG. 4 in the example of the figure, but the example of FIG. 8, 11 or 13 described above may be used.
[0049]
In each of the above embodiments, the connecting member is separated from the base, and the connecting member is inserted and fixed between an opening or a side wall provided in the base. However, the connecting member may be formed integrally with the base. In this case, a locking piece as a connecting member is provided on the base, an opening or the like is formed on the terminal side, and the locking piece of the base and the opening of the terminal are fitted and coupled. In any case, since the terminal is coupled to the base via the connecting member, the terminal and the base are separate.
[0050]
【The invention's effect】
As described above, according to the present invention, since the base and the terminal are separate, it is possible to form a terminal with different types of shapes by combining a base with a certain standard shape and various types of terminals with different shapes. Therefore, even if it is a different kind of terminal, the soldering operation | work of a different terminal can be unified by joining a terminal after adhere | attaching only the base of a fixed shape to a window glass first. For this reason, since the bonding operation of the base can be performed in a fixed pattern, it is possible to automate the bonding of the base to the window glass, the mounting time is quick, and the workability is improved. When the shape of the base is symmetric, it is particularly preferable for automation. In addition, automation eliminates the need for soldering skills and skill, eliminates variations in the bonding state due to differences in worker skills, and makes it possible to always adhere highly reliable terminals.
[0051]
Further, since different types of terminals can be bonded to the window glass using a common base, it is not necessary to distinguish the bonded components, and the component management and product management of the solder bonding process are simplified. In addition, when the terminal and base are detachable, if the terminal needs to be replaced due to maintenance, etc., only the terminal can be removed. Improves.
[0052]
When transporting the glass with a terminal, when the connecting member is separated from the base, the glass interval can be narrowed during glass transport, and more glass can be transported at one time.
[0053]
The connecting member is integrated with the terminal by inserting the connecting member into the opening provided in the rising portion of the base from the side and engaging and engaging the engaging piece holding portion and the engaging piece protrusion provided on the connecting member. Since the locking piece of the connecting member is securely locked and fixed to the base, the terminal does not come off the base even if an upward force is applied to the terminal when the coupler is connected.
[0054]
In addition, the engaging piece of the connecting member is inserted into the opening of the upper surface of the base from above and rotated by 90 °, and the engaging piece of the connecting member is hooked on the base and the convex portion is fitted into the hole of the base, The integrated connecting member is easily fixed and held from above with respect to the base, and the terminal does not come off the base when the coupler is connected to the terminal.
[0055]
In addition, a claw piece is provided on the connecting member, and an inwardly inclined side wall is provided on the upper surface of the base so that the claw piece is securely locked and fixed to the opening on the upper surface of the base. The terminal does not come off the base when installing the coupler. In addition, since the inclined side walls on both sides of the upper surface of the base are in pressure contact with the connecting member to bring the connecting member into close contact with the upper surface, resistance loss when electricity is passed through the terminals is reduced, and power loss is reduced and power is efficiently supplied. can do.
[0056]
Also, by connecting the connecting member separately from the terminal and providing the terminal at a position away from the base via the lead wire, the coupler and terminal for external connection can be connected at a position away from the base, so the force at the time of connection Will not work on the base. Therefore, the adhesive strength between the base and the bus bar and the coupling strength between the connecting member and the base are ensured stably.
