Abstract

The present invention provides a connector and, more specifically, relates to an RAST connector for home appliance system, which comprises: a housing having a first surface and a second surface opposite to each other in the thickness direction of the housing; a first foolproof installation key formed on the first surface and adapted to match with a first foolproof installation slot formed in a matching connector; and a stop portion formed on the second surface of the housing and adapted to match with a stop portion formed on the matching connector. A hook is formed on the first foolproof installation key and a recess, configured to match with the hook, is formed in the stop portion of the connector. The hook is adapted to engage the recess and the connectors are sequentially linked by engaging the hook of the connector with the recess of the other connector. According to the present invention, the existing and required foolproof installation keys on the connector are used as a chain structure to link the connectors, and the foolproof installation key is an essential feature of the final product. This simplifies the manufacturing process of the connector since there is no need to cut out the existing and required foolproof installation key in the subsequent process.

The present application claims the benefit of Chinese Patent Application No. CN201520475958.6, filed on June 30, 2015, filed with the Chinese Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.

Technical field

The present invention relates to a connector, and more particularly to a RAST connector for a home appliance system.

Currently, standardized and modular RAST (where RAST is the abbreviation for the German phrase "Raster Anschluss Steck Technik") connector systems are widely used in consumer electronics. The RAST connector not only has many technical advantages, but also achieves a highly modular system. As the functions of household appliances increase, the number of connectors for connecting functional modules to the main controller is correspondingly increased. The standardized and modular RAST connector system can be integrated into a plurality of connectors, and a plurality of single devices, saving installation time and reducing risk of human installation errors. On the other hand, since the number of components to be installed is reduced, this reduces the manufacturing cost and occupied space of the PCB.

In the prior art, in order to realize the automatic manufacturing of the RAST connector, before the crimping of the contacts and the wires of the connector, the contacts and the connectors are connected to the station to be crimped together by means of a conveyor belt, It is necessary to link a plurality of connectors together.

To link a plurality of RAST connectors together, in the prior art, an additional chain structure is formed on the housing of the RAST connector. An additional chain structure is only used to link a plurality of RAST connectors together. After the contacts and wires are crimped together, the additional chain structure must be cut off from the housing of the connector. Otherwise, a match between the connector and the mating connector will be hindered. That is, the additional chain structure is not a necessary feature of the final product of the connector, but a temporary feature.

In the prior art, it is necessary to add an additional chain structure on the housing of the RAST connector, and the additional chain structure is finally removed. This, in turn, increases costs and complicates the manufacturing process.

The present invention overcomes or alleviates one or more of the above-mentioned problems.

It would be advantageous to provide a connector in which the existing and required pull proof installation keys on the connector are used as a chain structure to link the connectors.

A pair of first pull proof installation keys 110 is formed on the first surface 100a of the housing 100 and is mated with a pair of first pull proof installation slots 110 'formed in the mating connector 10' (See FIG. 4). In this way, prior to mating the connector 10 and the mating connector 10 'together, the first pull proof mounting keys 110 of the connector 10 are inserted into the first pull proof mounting slots (not shown) of the mating connector 10' 110 '); Otherwise, the connector 10 and the matching connector 10 'can not be matched together. Thereby, the first full-proof installation keys 110 can prevent the connector 10 from being connected incorrectly, such as being connected to the mating connector 10 'in an incorrect posture or to a mismatched connector .

Referring to Figures 1, 2 and 4, in an embodiment, a pair of stop portions 130 are formed on the second surface 100b of the housing 100, and the mating connector 10 '(Figure 4 (See FIG. 1). In this way, when the connector 10 and the mating connector 10 'are mated together, the stop portions 130 of the connector 10 abut the stop portions 130' of the mating connector 10 ' Thereby preventing one of the connector 10 and the matching connector 10 'from being excessively inserted into the other.

In an embodiment, the stop portion 130 of the connector 10 includes a stop surface 132, as shown in Figures 1, 2 and 4. When the connector 10 and the mating connector 10 'are mated together, the stop surface 132 of the stop portion 130 of the connector 10 contacts the stop surface 130' of the stop portion 130 'of the mating connector 10' Abutting and abutting against the connector 132 'to prevent one of the connector 10 and the mating connector 10' from being excessively inserted into the other.

1, 2 and 4, the first end of the housing 100 of the connector 10 has a first end that is aligned with the first end of the connector 10, Is inserted into the insertion chamber of the housing 100 'of the connector 10' and the plug 101 'of the matching connector 10' is inserted into the insertion slot 101 of the connector 10 '. As a result, the contact 102 'on the plug 101' of the matching connector 10 'is electrically connected to the contact 102 in the insertion slot 101 of the connector 10.

Note that both the first pull proof setup key 110 and the stop portion 130 are essential structural features of the connector 10. [ This eliminates the need to cut off the essential structural features after crimping the wires and contacts 102 together. According to embodiments of the present invention, these essential structural features are configured to be used as chain structures to link the plurality of connectors 10. Hereinafter, this will be described in detail with reference to the drawings.

As shown in FIG. 1, in the embodiment, a hook 111 is formed on a first pull proof setup key 110. A recess 131 configured to mate with the hook 111 is formed in the stop portion 130 of the connector 10, as shown in Fig. The hook 111 is configured to be engaged with the recess 131 so that the plurality of connectors 10, 10 and 10 (see FIG. 3) can connect the hook 111 of one connector 10 to the other connector 10, By being engaged with the recesses 130 of the frame 130. In this way,

Fig. 3 is an example of linking the connectors 10 of Figs. 1 and 2 by the chain structures formed above.

As shown in Figures 1 to 3, a plurality of connectors 10, 10, and 10 may be formed by engaging the hooks 111 of one connector 10 with the recesses 130 of the other connector 10, Link together. In this way, the plurality of connectors 10, 10, 10 linked together can be continuously transferred to the station by means of a conveyor belt, where the contacts 102 and the wires are connected by the arrow S Along with the conveying direction indicated.

1, a first pull proof installation key 110 is formed at a location on the first surface 100a of the housing 100 adjacent the first end of the housing 100. As shown in FIG. The stop portion 130 of the connector 10 is formed at a position on the second surface 100b of the housing 100 adjacent to the second end of the housing 100. [

2, a second pull proof installation key 120 is formed on the second surface 100b of the housing 100 and the second pull proof installation key 120 of the matching connector 10 ' Slot 120 '.
