Abstract

A device for connecting an electrical lead to the heating element or thermostat in a domestic iron, is characterised in that the device with its connection lead (4) pilot light (7) and connection terminals (3), is constructed to facilitate automatic assembly and mounting on an iron. Terminals (3) are aligned by a spacer (10) and are mounted on respective contact pieces (11) clipped to the body (1) of the device. <IMAGE>

Description

SPECIFICATION Connection assembly for domestic irons The invention relates to a device for connection of the electric current and for conveying it from the connection line to the heating element in domestic irons. This connection line and its mounting supports serve to convey the current inside the appliance.

Known technical systems are provided with individual electrical connection lines which can only be positioned and connected up by hand. For connecting up the line individual terminal points and terminal bars or ordinary commercial terminal bars to be connected by plugs or screw contacts are available. The internal connections are produced by rigid or flexible wires, either insulated or bare, or with bare strips. These constuctional versions cannot be combined to form an assembly or automatically manufactured and mounted.

The purpose of the invention is to change the position of manual working devices suffering from subjective defects in such a way as to improve the reliability or production and increase the quality and safety of the apparatus by means of a connection assembly tested before the final mounting operation. A further object is to enable the subsequent finishing processes, necessitated by defects in the material or by subjective faults, to be considerably reduced. The invention enables this object to be achieved as a result of the fact that the connection lines and connections known perse are so constructed and dimensioned that they can be automatically manufactured, combined to form a complete assembly and stacked, while this assembly can be automatically mounted on the appliance.

All lines for connection to the heating element or thermostat, including the pilot light, are so constructed that their shape and position are secured by a mounting aid. The other end of the lines and the connection part for the outer supply lead are likewise so constructed that the contact point is secured in shape and position and also cannot be by-passed. According to the invention the basic body can be made of a thermoplastic or duroplastic material. The connection assembly is so constructed that the entire electrical part can be mounted automatically and also electrically tested automatically outside the appliance itself.

The invention will be explained in greater detail by reference to the constructional examples shown in the drawings.

The diagrams are as follows: Fig. 1: A plan view of a constructional example of the complete connection assembly, capable of being automated and also automatically tested, in accordance with the invention.

Fig. 1 shows how the individual parts capable of being automated interact to form a constructional assembly. The basic body 1 consists of duroplastic material and is so constructed that it can accommodate all the individual components required. The clamping piece 2 is so constructed that it can be easily fitted into the basic body 1 automatically. The connecting strip 3 serves to convey the current to the heating body or thermostat. The connection lead 4 is affixed by means of the traction relief device 5 and clamped to the contact point 6. The pilot light 7 with an elastic casing 8 can be easily fitted automatically into the mounting support provided. The electrical connection of the pilot light 7 is effected, for example, by means of plug connectors. For this purpose the meter contact 9 in the connecting strip 3 is sheared through.A spacer 10 can be provided for the exact positioning of the connecting strips. Fig. 2 shows the position and construction of the individual parts. The clamping piece 2 is affixed in the basic body 1 by bending the strap 11. Fig. 3 shows an example for the mounting of the pilot light. An undercut part 12 enables an elastic body 8, such as a flexible insulating tube, to engage easily.

Fig. 4 shows a mounting support system for the connecting strip 3. In the basic body 1 a rib 13 with an undercut part 12 is pressed against the surface, a release device 14 in the connecting strip 3 engaging the said part. The passage can preferably be utilized for the meter contact.

Fig. 5 shows by a different embodiment how the individual parts capable of being automated interact to form a constructional assembly. The basic body 1 serves to accommodate the four contact points 6 for the connection of the line 4 coming from the outside and for conveying the current onward internally be means of connecting strips 3. The basic body 1 is preferably made of an elastic thermoplastic material. The mounting support systems in the basic body 1 for the clamping pieces 2 and connecting strips 3 are constructed with bevels for easy insertion and with undercut parts for engagement. The clamping pieces 2 and the connecting strips 4 can thus be easily fitted into the basic body 1 automatically. A centering device 15, for securing the contact points 6 in position, is provided in the basic body 1 and the connecting strips 3.

The means by which the connecting strips 3 are secured in position and at the right distance for contact with the heating body and thermostat consists of a spacer 10.

In the connecting strip 3 straps 16 in the spacer 10 are sheared through and engage corresponding recesses in the spacer 10. This enables the spacer 10 to be automatically fitted to the connecting strips 3 and to be held in position.

Fig. 6 shows the position and construction of the individual parts of the constructional assembly capable of being automated. The contact point 6 is formed by a clamping piece 2 tightly fitted into the basic body 1, by the outer connecting line 4 and by the connecting strip 3. The straps 16 are sheared through obliquely. This enables the spacer 10 to be automatically fitted with ease and the straps 16 to be then automatically bent over.

Fig. 7 shows an example of how the elastic basic body 1 is constructed with bevelled insertion parts 17 for the reliable automatic mounting of the clamping piece 2. The undercut parts 18 provide a firm mounting support system for the said clamping piece 2.

In Fig. 8 the elastic basic body 1 is again constructed with insertion bevels 17 for the reliable automatic mounting of the connecting strip 3. The centering device 15 secures the connecting strip 3 in position as required. The undercut parts 18 provide the required mounting supporting system for the connecting strip 3. In conjunction with Figs. 1-8 a description has been given of examples of how individual parts can be constructed in order to manufacture them automatically, render them capable of being stacked and combine them in the form of an assembly and mount them in position.

The assembly is so constructed that it can be stacked and automatically connected to an appliance and mounted in position.
