Abstract

PURPOSE:To connect leads to the terminal of a heat emitting element simply and congestedly by furnishing a clamping part for clamping of terminal electrodes of the heat emitting element, arms provided on both sides of the clamping part, and leads fixed to these arms. CONSTITUTION:The mouth 1a of a clamping part 1 is widened by an inward pressing force applied to arms 2a, 2b and mounted to a columnar terminal electrode of a heat emitting element. That is, even through the pressing force applied to the arms 2a, 2b is removed, the clamping part 1 is put in pressure contact with the outside surface of the terminal electrode, with the tip 3a of a meshed band 3 interposed, through the action of the resilience of the clamping part itself 1. The terminal electrode and the tip 3a of meshed band 3 are put in such a condition that a number of line contacts are gathered, and connections of leads are obtained with high reliability. The tip 3a of the meshed band 3 on the inner side face of the clamping part 1 has an effect to increase the contacting area with the terminal electrode, which ensures increased reliance upon the connection. Because the tip 3a secured to the inner side face of the clamping part 1 uniformly and with satisfactory strength, there is no risk of generation of poor contacting.

Description

[Detailed Description of the Invention] Rikurikamibei M Moon Duke! The present invention relates to a clip with a lead wire attached to a terminal portion of a heating element that constitutes a part of a heater component.

Traditionally, as shown in Figure 8, non-metallic heat generating materials (e.g.
When connecting a lead wire (mesh band wire) 42 to a rod-shaped heating element 40 made of silicon carbide, etc., first wind the lead wire 42 around the cylindrical terminal electrode 41 of the heating element 40, and then, as shown in FIG. As shown in Figure 1, the lead wire 42 was held down and connected by a metal knob 43. However, this lead wire connection using the clip 43 connects the lead wire 42 to the electrode 41.
The work of winding the lead wire 42 and the electrode 41 may be complicated, or there may be poor contact between the lead wire 42 and the electrode 41, or
There have been problems in that the terminal end portion of the lead wire 42 is not completely suppressed, and a portion of the wire may short-circuit to another adjacent terminal electrode.

Moreover, as shown in FIG. 10, two heating elements 5 placed opposite each other
When connecting lead wires 59a and 59b to 0a and 50b, insulating terminal plates 52a and 52b are inserted between semi-cylindrical terminal electrodes 518 and 51b of heating elements 50a and 50b, respectively. Holding metal fittings 57 were arranged on the upper and lower surfaces. The holding fittings 57 were pressed against the electrodes 51a, 51b by screws 55 and nuts 56 made of insulating material, and were completely fixed to the terminal plates 52a, 52b. At the same time, the lead wires 59a and 59b are connected to the holding plate 54.
(The holding plate on the lower surface side of the terminal plate 52b is not shown) and the holding fitting 57, and the screw 55 and the nut 5
It was screwed in by 6. In this way, the lead wire 5
9a and 59b were connected to electrodes 51a and 51b, respectively. However, this connection method uses the lead wire 598.
In order to prevent short-circuiting between the terminals 59b and 59b, it was necessary to use terminal plates 52a and 52b with large external dimensions, holding fittings 57, and the like.

Therefore, these terminal plates 52a, 52b, holding fittings 57
etc. had problems such as not being able to be used in locations where node lines must be connected closely.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a clip with lead wires that allows lead wires to be easily and densely connected to the terminal portion of a heating element.

Means and Function for Solving the Problems In order to solve the above problems, the clip with lead wire according to the present invention includes: (a) a clamp portion for clamping the terminal electrode of the heating element; (b) both sides of the clamp portion. and (c) a lead wire fixed to the arm.

With the above configuration, one end of the lead wire is fixed to the arm in advance, so all that is required to connect the lead wire is to clamp the terminal electrode of the heating element with the clamp part. There is no need to wind the lead wires.

Furthermore, there is no risk that a portion of the terminal end of the lead wire may protrude from the clip body and short-circuit with other adjacent terminal electrodes or the like.

Furthermore, the clip with lead wire according to the present invention is (d)
(e) arm parts provided on both sides of the clamp part; (f) a tip part of the clamp part; and (g) a lead wire fixed to the arm.

The clip with the above structure clamps the approximately semi-cylindrical terminal electrode of the heating element with its clamp part,
Attached to each terminal electrode. At this time, the pair of clips are arranged so that the insulators provided at the tip portions of the clamp portions face each other, and the insulators ensure insulation between the clips and, by extension, between the terminal electrodes. This eliminates the need for the conventionally used terminal board, and the area occupied by the lead wire connection portion can be reduced.

Embodiments Hereinafter, embodiments of the clip with lead wire according to the present invention will be described with reference to the accompanying drawings.

[First Example, Figures 1 and 2] This example shows a clip that secures a reticulated band wire.

The clip body includes a substantially cylindrical clamp part 1 having a mouth part 1a, arm parts 2a integrally provided on both sides of the clamp part 1,
It consists of 2b. The clamp portion 1 is made of a material with excellent spring properties, such as spring steel. One end portion 3a of the reticular band wire 3 functioning as a lead wire is inserted through a slit provided in the clamp portion 1 near the arm portion 2b, and then electrically connected to the inner surface of the clamp portion 1 and fixed. ing.

Further, the relay portion 3b of the mesh band wire 3 is electrically connected and fixed to the upper surface of the arm portion 2b by means such as welding or brazing.

The clip with a lead wire thus obtained has an arm portion 2a,
A pressing force is applied inward (in the direction of the arrow in FIG. 1) to 2b to widen the mouth portion 1a of the clamp portion 1, and the clamp portion 1 is attached to the cylindrical terminal electrode of the heating element. That is, even if the pressing force applied to the arm parts 2a and 2b is removed, the clamp part 1 retains the tip end 3a of the reticulated band wire 3 due to its own spring properties.
Pressure contact is made to the outer peripheral surface of the terminal electrode via the terminal electrode. The terminal electrode and the tip portion 3a of the reticular band wire 3 are in a state where a large number of wire contacts are assembled, and a lead wire connection with high connection reliability can be obtained.

The tip portion 3a of the mesh band wire 3 on the inner surface of the clamp portion 1 has the effect of increasing the contact area with the terminal electrode, and has the effect of increasing connection reliability. Since the tip portion 3a is fixed uniformly and with sufficient strength to the inner surface of the clamp portion 1,
The contact failure that conventionally occurs when a reticulated band wire is wound around a terminal electrode does not occur. Moreover, since the tip end portion 3a of the mesh band wire 3 is fixedly fixed to the inner surface of the clamp portion 1, there is no risk of it protruding from the clip body and causing a short circuit with other adjacent terminal electrodes or the like.

[Second Example, Figures 3 and 4] This example shows a clip securing a copper cable.

The clip main body is composed of a substantially cylindrical clamp part 11 having a mouth part 11a, and arm parts 12a and 12b integrally provided on both sides of the clamp part 11. The clip body is made of electrically conductive spring steel. A conductive mesh pad 13 is electrically connected and fixed to the inner surface of the clamp part 11. One terminal end 14a of the copper cable 14 serving as a lead wire is electrically connected and fixed to the upper surface of the arm 12b. Similar to the first embodiment, this clip is constructed by applying an inward pressing force to the arm portions 12a and 12b (in the direction of the arrow in FIG.
is unfolded and attached to the cylindrical terminal electrode of the heating element. That is, even if the pressing force applied to the arms 12a and 12b is removed, the clamp part 11 is pressed against the terminal electrode via the pad 13 due to the spring property of the clamp part 11 itself.

In this way, the terminal electrode and the copper cable 14 can be electrically connected.

The functions and effects of this embodiment are the same as those of the first embodiment.

[Third Example, FIGS. 5 to 7] This example shows a clip used for a spiral heating element terminal electrode.

The clip body includes a roughly semi-cylindrical clamp part 21 having a mouth part 218, arm parts 22a and 22b integrally provided on both sides of the clamp part 21, and insulators 25a and 25b provided at the tip of the clamp part 21. It consists of

The clip body is made from conductive spring steel.

A conductive mesh pad 23 is electrically connected and fixed to the inner surface of the clamp portion 21. One terminal end 26a of the copper cable 26 is fixed to the upper surface of the arm 22b.

Next, a method of attaching this clip to a spiral heating element terminal electrode will be explained.

As shown in FIG. 6, two opposing heating elements 30a,
The semi-cylindrical terminal electrodes 31a and 31b of 30b are fixed with a holder 32 made of an insulating material with a gap between them. This clip has an arm portion 22 as shown in FIG.
By applying a pushing force in the inward direction (in the direction of the arrow in FIG. 5) to a and 22b, the opening 21a of the clamp part 21 is expanded, and the semi-cylindrical terminal electrode 31a of the heating element is opened.
31b. At this time, the two clips are insulators 25a and 2 provided at the tip of the clamp part 21.
5b are arranged to face each other, and the insulators 25a, 2
5b ensures insulation between the two clips. Therefore, the conventional terminal board is no longer necessary, and in addition to the effects of the clip of the first or second embodiment, this clip has the advantage that it can be used in places where lead wires must be connected closely together. There is.

[Other Examples] Note that the clip with lead wire according to the present invention is not limited to the above-mentioned embodiments, and can be variously modified within the scope of the gist thereof. In particular, the pads 13, 23 do not need to be mesh-like as long as they are made of conductive elastic material. however,
Pads 13.23 are not absolutely necessary in the invention.

As described above, in the clip with lead wire according to the present invention, the lead wire is fixed to the arm of the clip in advance, so there is no need to wrap the lead wire around the terminal electrode of the heating element, and the lead Wire connection work can be simplified and costs can be reduced. Moreover, a portion of the terminal end of the lead wire does not protrude from the clip body, and there is no risk of short-circuiting with other adjacent terminal electrodes, thereby improving the safety of the lead wire connection.

Further, the clip with lead wires according to the present invention allows the lead wires to be connected in a dense manner by fixing the lead wires to the arm portions of the clip in advance and providing an insulator at the tip of the approximately semi-cylindrical clamp portion. It can also be used where necessary.
