DE4110320C1 - Simple and reversible plug connection - comprises cooling elements formed of arched wall-sections and associated contact elements - Google Patents

Abstract

Plug connection consists of two parts (1,2) each of which has cooling elements (3a,4a). The cooling elements are formed by opposite facing arched wall sections, each contact element being associated with a cooling element. A cooling element in one half of the connection cooperates with the corresp. cooling element on the other half. ADVANTAGE - Simple and reversible.

Description

The invention relates to a connector according to the generic term of Claim 1. A typical application of such coded connectors are multi-pin electrical connectors, which often, for example in switchgear, several times next to each other lie, so that each other by an appropriate coding belonging connector parts should be prevented that at Repair and maintenance work.

Plug connections with coding elements are known (DE 21 44 768 B1, DE 29 40 457 A1), in which on both connector parts in for Contemplated recordings each contoured to match separate coding elements are to be installed, the assembled Connectors running transversely to the direction of insertion with wall parts their housings lie against each other and they have different patterns are to be arranged. Corresponding assembly work is therefore required Attachment of the coding elements to the connector parts required. Coding elements can be lost. Although the coding process basically reversible, but errors can occur during coding also remain undetected.

So far you used to with molded, breakable coding elements has worked, the coding process is not in case of an error reversible.  

In both cases, the coding process requires a very high level of attention speed.

The present invention is therefore based on the object Codable connector to create the simple, lossless and is to be reversibly encoded.

The solution according to the invention results from the characterizing part of the Claim 1.

Coding using the cooperating curved, elastic, in two oppositely directed tilt-stable bulge layers can be transferred Wall sections on the two connector parts enables the Advantage as separately to be assembled or separately previously and then coding elements to be broken off. However, assembly is not required operations. There is no waste of coding elements that are not required on the usual carrier strips or carrier discs with which So far, the separately assembled coding elements have been stocked many times will. Incorrect coding is hardly possible because during the initial assembly the connector in mated connector parts this in their already assembled state together and simultaneously can be encoded. If you practice a force on each other lying pair of elastic curved wall sections, both Wall sections transferred together in the opposite curvature. The coding is also, especially in the event of later changes work and reuse, reversible at any time because of the wall sections can also be returned to the other bulge position. It also eliminates the need for the two connector parts to have to code separately. The coding is by the operating personnel very easy to do. There are no complicated assembly or disassembly tools required. For transferring the wall sections in one or the other bulge position, a standard one is sufficient Screwdriver. Therefore, this coding system is also suitable in  especially for automation in series production, in the case of, for example, a corresponding cam bar Control a multi-pin electrical connector, for example such a coding is assigned to each contact element, in can be completely encoded in one operation.

According to a preferred embodiment, the elastic, arched Wall sections on sections of the plastic housing of the connector molded parts. The wall sections can be for example from the production of so-called film hinges known injection molding techniques inexpensively.

An embodiment of the subject of the invention is shown below described in more detail with reference to the drawing.

Fig. 1 that match each other coded male and female parts of a connector in perspective from the front,

Fig. 2 are front views of the plug-in part and the receiving part in unkodiertem state with dash-dotting ter illustration of the later coding,

Fig. 3 shows a cross section through the plug connection formed from the receiving part and the plug part of FIG. 1 after the coding.

In the illustrated embodiment, a connec tion in the form of a multi-pole electrical connec tion is shown, in which the plug part 1 is a pin strip, while the receiving part 2 is a socket strip. In this embodiment, each of the four contact elements of the plug-in part 1 and the associated receiving part 2 is assigned a coding. For this purpose, each on housing sections 3 of the plug-in part 1 and on Ge housing sections 4 of the receiving part 2 with respect to the respective pin or with respect to the respective socket on opposite sides of the plug-in part 1 elastic, arched wall sections 3 a and on the receiving part 2 corresponding curved, elastic Wall sections 4 a formed. After the connection has been made, that is to say after the plug-in part and the receiving part 2 have been inserted into one another, as can be seen from FIG. 3, the elastic, curved wall sections 3 a of the plug-in part 1 and 4 a of the receiving part 2 are adjacent to one another.

The resilient curved wall sections 3a, 4a can be integrally formed by injection molding in the housing sections 3.4 and at such a film-hinge-like configuration in the transitional region of the thin elastic wall portions 3 a, 4 a th in relation to the Gehäuseabschnit 3, 4, that the wall sections 3 a, 4 a in their two opposing curvature layers are each tilt stable.

The coding formed by the wall sections 3 a, 4 a permanently and permanently on the parts 1 , 2 can be carried out in a very simple manner after the plug connection has been made. In Fig. 3 is illustrated by arrows, such as by simply pushing in, for example by means of a screwdriver or in the context of automatic production using a corresponding cam arrangement, some of the adjacent wall sections 3 a, 4 a from the uncoded initial position, in the exemplary embodiment shown from the following externally arched position can be jointly transferred to the coding position, corresponding to an inwardly arched position. In the illustrated embodiment, the coding is shown in FIG. 3 occurred on the upper side and lower side at the right outer pole, while the coding is carried out on the underside at the second pole from the left.

In Fig. 2, in the area of the corresponding contact elements, the change in spatial position of the coded wall sections 3 a, 4 a is illustrated with dashed lines. This clearly shows the collision position of these wall sections 3 a, 4 a when they are joined together with a differently coded part.

Fig. 1 illustrates match each other coded parts 1 and 2. It can be seen from the respective position of the Wandab sections 3 a, 4 a that these parts can be easily inserted into one another.

The common coding of the parts 1 , 2 in the inserted state practically excludes incorrect coding. Since coded wall sections 3a, 4a may be recycled back to the starting position a problems, the encoding process is also reversible. The parts can thus be easily adapted to another coding system as part of changes or the like. The different positions of the wall sections 3 a, 4 a after the coding also allow the coding state to be clearly identified.
