Description

  The present invention relates to a connection component that electrically connects a planar electrode provided on an outer surface of a plate-like member and an electric wire.

  Conventionally, a heater wire for preventing fogging is attached to a windshield or the like of an automobile (see, for example, Patent Documents 1 to 3). In recent years, not only the above-described windshield but also the above-described heater wire or the like is attached to a window glass that is attached to an automobile door and moves in the vertical direction. Conventionally, for example, a connection structure 100 shown in FIG. 10 is used as a connection structure for connecting the heater wire of the window glass and an electric wire for supplying power to the heater wire.

  FIG. 10 shows a connection structure 100 that connects the conductor pattern 121 as the heater wire and the electric wire 103. This connection structure 100 electrically connects the conductor pattern 121 and the electric wire 103 by soldering the terminal fitting 104 attached to the electric wire 103 to the conductor pattern 121.

  The conductor pattern 121 is formed by applying a conductive paste to the outer surface of the window glass 102 as a plate-like member. Both end portions of the conductor pattern 121 form a planar electrode 122. The terminal fitting 104 is formed by bending a sheet metal. The terminal fitting 104 includes an electrical contact portion 141 and a wire connection portion 142. The electrical contact portion 141 is formed in a flat plate shape, overlapped with the planar electrode 122, and is electrically connected to the planar electrode 122 via solder. The electric wire connecting portion 142 includes a bottom plate portion on which the end portion of the electric wire 103 is placed and a crimping piece for caulking the core wire of the electric wire 103, and the caulking piece caulks the core wire of the electric wire 103, Electrically connected.

In the connection structure 100 described above, when the window glass 102 or the door is in an open state, liquid such as rainwater is applied to the contact between the planar electrode 122 and the electric contact portion 141, the contact between the core wire of the electric wire 103 and the electric wire connection portion 142, or the like. There was such a problem. In addition, even when the window glass 102 or the door is closed, there is a problem that water or the like that is condensed on the outer surface of the window glass 102 is applied to these contacts. For this reason, in the connection structure 100, after the terminal fitting 104 is soldered to the planar electrode 122, the waterproofing is performed by applying an insulating coating agent to the above-described contacts and the like (portion H surrounded by a two-dot chain line in FIG. 10). We were processing.

  However, in the connection structure 100 described above, since the terminal fitting 104 and the planar electrode 122 are connected by soldering, there is a problem that the connection work is complicated and the workability is poor. Also, the use of solder is not preferable in consideration of environmental aspects. Further, since the contact point described above is waterproofed after the terminal fitting 104 is soldered to the flat electrode 122, there is a problem that the number of work steps increases and workability is poor. Furthermore, since the window glass 102 is assembled to the door after the terminal fitting 104 or the electric wire 103 is attached to the window glass 102, the handleability and the assembly work of the window glass 102 in the assembly line to the door are performed. There was a problem that the nature was bad.

  The present invention aims to solve such problems. That is, an object of the present invention is to provide a connection component that can electrically connect a planar electrode and an electric wire with an easy operation.

  In order to solve the above problems and achieve the object, the invention described in claim 1 is a connecting part for electrically connecting a flat electrode formed on an outer surface of a plate-like member and an electric wire, A terminal fitting to be attached to the electric wire; a housing for accommodating the terminal fitting therein; a clamping portion that is made of an elastic material and that is attached to the housing and sandwiches the plate-like member; and is attached to the clamping portion, And a conductive portion that is electrically connected to the planar electrode when the clamping portion sandwiches the plate-like member. It is a connecting part.

A first contact portion that is in close contact with the plate member, and a second contact portion that is in close contact with the plate member or the planar electrode so as to surround a contact point between the planar electrode and the other end of the conductive portion. This is a connection part characterized by this.

  According to the first aspect of the present invention, a sandwiching portion that is made of an elastic material and sandwiches the plate-like member, and is attached to the sandwiching portion and is electrically connected to the terminal fitting and the sandwiching portion is a plate. Since the other end portion includes a conductive portion electrically connected to the planar electrode when the shaped member is sandwiched, the sandwiched portion sandwiches the plate-like member, so that the connecting component is attached to the planar member and is planar. The electrode and the electric wire are electrically connected. Therefore, it is not necessary to perform soldering, and the planar electrode and the electric wire can be electrically connected by an easy operation of attaching the connection component to the plate-like member. Further, since there is no need for a separate part for attaching the connection part to the plate-like member, the number of parts can be reduced and the cost can be reduced.

  According to the second aspect of the present invention, the sandwiching portion includes the first contact portion that is in close contact with the housing or the terminal fitting so as to surround the contact point between the terminal fitting and the one end portion of the conductive portion, the planar electrode, and the conductive member. Since the second contact portion that is in close contact with the plate-like member or the planar electrode is provided so as to surround the contact point with the other end of the portion, the two contact points are reliably waterproofed. Therefore, it is not necessary to separately perform waterproofing on these contacts, and the number of work steps can be reduced.

However, as long as the contact S2 can be surrounded. The window glass 2 may be in close contact with only the outer surface, or may be in close contact with the planar electrode 22 only. Moreover, if the 1st contact part and 2nd contact part of this invention are closely_contact | adhered so that contact S1 and S2 may be enclosed, respectively, the shape will be the 1st contact part 64 of embodiment mentioned above, The shape of the first rib 65 and the second rib 66 is not limited. For example, the second contact portion may be formed in the same shape (annular shape) as the first contact portion 64 on the back side of the first contact portion 64 on the inner surface of the one side wall 62a.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.

It is a front view which shows the state which the connection component concerning one Embodiment of this invention connected the plane electrode and the electric wire. It is a disassembled perspective view of the connection component shown by FIG. It is a perspective view which shows the state by which the terminal metal fitting and the waterproof plug were attached to the electric wire shown by FIG. It is sectional drawing of the housing along the IV-IV line in FIG. It is a perspective view which expands and shows the connection body shown by FIG. It is sectional drawing along the VI-VI line in FIG. FIG. 3 is a perspective view illustrating a state in which the connection component illustrated in FIG. 2 is assembled and the planar electrode and the electric wire are connected. It is sectional drawing along the VIII-VIII line in FIG. It is sectional drawing which expands and shows the IX part in FIG. It is a front view which shows the connection structure which connects the conventional plane electrode and an electric wire.
