The means for connecting a lead wire to an aluminum plate by soldering as shown in FIG. 3 is inferior in workability of soldering, and depends on the amount of heat at the time of soldering. May be damaged.

In the case of using the screw fixing means shown in FIG. 4, it is necessary to integrally connect a screw fitting to the tip of the lead wire, and the screw fixing portion is loosened when the lead wire is drawn. It is also conceivable that the electrical continuity is hindered.

Therefore, when connecting a lead wire to an aluminum plate, there is a technical problem to be solved in order to connect the aluminum plate and the lead wire, which simplifies the connection work and increases the connection strength. Therefore, the present invention aims to solve the problem.

DISCLOSURE OF THE INVENTION The present invention has been proposed to achieve the above object, and a lead wire having a lower hardness than an aluminum material is attached to an end of an aluminum plate constituting a connection terminal piece. The aluminum plate is disposed orthogonal to the longitudinal direction, and a small hole is formed in the end of the aluminum plate, and the aluminum plate is provided at the end of the aluminum plate. The lead wire is connected to the lead wire by crimping while crimping the end of the aluminum plate, and the lead wire is inserted into the small hole drilled at the end of the aluminum plate. The present invention provides a connection mechanism by caulking means between an aluminum plate and a lead wire which are partially engaged with each other to engage the small hole with a part of the lead wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In the figure, reference numeral 10 denotes a connection terminal piece, and reference numeral 11 denotes a lead wire connected to the connection terminal piece 10. Thus, the connection terminal piece 10 is formed in a substantially circular shape and protrudes from one end of the heat radiation plate 12 integrally formed by punching an aluminum plate. Therefore, the connection terminal piece 10 is also processed into a rectangular shape by an aluminum plate. Thus, the heat sink 1
Reference numeral 2 is mainly used for a vaporizer (not shown) using a PTC heater (not shown) having a self-temperature control function. Therefore, the radiator plate 12 corresponds to the upper electrode of the PTC heater. That is, the lower electrode (not shown)
The PTC heater is sandwiched between the radiator plate 12 and the radiating plate 12 constituting the upper electrode, and heats itself to a predetermined temperature. It is configured so that it can be heated.

Further, the lead wire 11 is connected to the connection terminal piece 10.
No solder means is adopted as means for connecting
Assume that both are connected by caulking means. At this time, a small hole 13 is formed in a substantially central portion of the end 10a of the connection terminal piece 10, and the end 10a of the connection terminal piece 10 is
When crimping is performed on the end of the lead wire 11 while curling, the small hole 13 is formed so as to face a part of the lead wire 11.

That is, the lead wire 11 is connected to the connection terminal strip 1.
0 of the connection terminal piece 10 by crimping means.
First, the lead wire 11 is connected to FIG.
As shown in the figure, the connection terminal piece 10 is disposed at an end 10 a in a direction orthogonal to the connection terminal piece 10. Therefore, when the lead wire 11 is arranged with respect to the end 10a of the connection terminal piece 10, there is no particular trouble such as centering. Thus, the end 10a of the connection terminal strip 10 is surrounded by the lead wire 11 disposed on the end 10a of the connection terminal strip 10.
Then, the end 10a of the connection terminal piece 10 is crimped to the lead wire 11 while curling. At this time, the lead wire 11
The facing portion of the lead wire 11 bites into the small hole 13 facing the hole, and both are strongly connected. That is, the lead wire 11 has a strong proof strength in the pulling-out direction due to the engagement between the small hole 13 and the portion of the lead wire 11 that bites into the small hole 13.

Since the lead wire 11 is selected to have a hardness lower than that of the aluminum plate, the end 10a of the connection terminal piece 10 which is crimped to the lead wire is firmly holding the lead wire 11. In addition, the lead wire can easily bite into the small hole 13 opened at the end 10a of the connection terminal piece 10 at the time of the caulking, so that the coupling force between the two can be further improved. Therefore, when assembling the radiator plate 12 connected to the lead wire 11 to the evaporator, for example, the lead wire 11 can be freely turned in an arbitrary direction. The work is also easy. Furthermore, the caulking portion is also formed within the width of the connection terminal piece 10, so that the routing of the lead wire 11 becomes unnecessary, and space can be saved.

The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified ones.

[0012]

According to the present invention, as described in detail in the above embodiment, a lead wire having a lower hardness than the aluminum plate is attached to the end of the aluminum plate constituting the connection terminal piece. The lead wires are arranged in a direction perpendicular to the longitudinal direction, and the ends of the connection terminal pieces are crimped and crimped to the lead wires while curling the ends of the connection terminal pieces. Since a small hole is previously drilled at the end of the piece, when the end of the connection terminal piece is crimped to the lead wire, a part of the lead wire bites into the small hole and the lead A proof stress in the wire drawing direction is provided. Therefore, for example, when assembling a heat sink which is stamped and formed integrally with the connection terminal piece by an aluminum plate to an evaporator or the like, the lead wire can be freely turned in any direction. Therefore, the work of assembling the heat sink is also facilitated. Furthermore, since the caulking portion is also formed within the width of the connection terminal piece, it is an invention which has a remarkably great effect such as eliminating the necessity of arranging the lead wire and enabling space saving.
