Connector element with fool-proof structure and its plug and socket

Abstract

The present invention is a connector element with a fool-proof structure and its plug and socket, wherein, a connector plug protrudes with a plurality of plug barrels, and these plug barrels are independently separated from each other, and a connector socket is concave. A plurality of socket chambers are provided, and the present invention is characterized in that a fool-proof block is provided between at least two adjacent plug cylinders, and the length of the fool-proof block is shorter than that of the plug cylinders, and it will be adjacent to another row or another The other two plug cylinders adjacent to one row; the cavity partition wall between at least two adjacent socket cavities, the partial area of ​​which will be recessed to form a fool-proof gap, and the fool-proof gap will be adjacent to another row or another The other two receptacle chambers next to each other in a row; when the connector plug is plugged into the connector receptacle in the correct way, the fool-proof block will protrude into the fool-proof gap, otherwise, the fool-proof block will be blocked .

Description

technical field [0001] The present invention relates to connector elements, and more particularly to a connector element whose fool-proof structure is located away from the outer wall of the respective connector. Background technique [0002] Signal connector (Connector) refers to all connecting components and accessories used in electronic signal and power transmission. It is a bridge for current and signal transmission in all electronic devices. Its quality not only has a great influence on the reliability of current and signal transmission. The extremely critical and important influence is also closely related to the normal operation of the electronic system. [0003] With the increasing development of electronic technology, signal connectors have become an indispensable and necessary component of various electronic devices for data transmission and connection with other peripheral equipment, and with the increasingly thinner and shorter designs of various electronic devi...

Problems solved by technology

When the connector plug A1 and the connector socket A3 are inserted into each other in a correct manner, the barrels A12 will respectively protrude into the corresponding chambers A33, and the plug terminals A2 can be electrically connected to the corresponding socket terminals A4, The key A13 can be placed in the keyway A34; otherwise, the connector plug A1 and the connector socket A3 cannot be inserted smoothly.

[0005] However, the applicant found that the connector elements of the prior art are still partially missing in use, please continue to refer to Figure 1A to Figure 1C As shown, at first, the width of the keyway A34 is formed by the distance between the "sheet body A37" and the "inner wall of the chamber A33", wherein, since the keyway A34 is located away from the remaining chambers A33, as Figure 1C As shown, the side wall of the connector socket A3 corresponding to the keyway A34 hardly has any support structure. According to the main trend of connector design in the prior art is light and thin, the side wall of the aforementioned connector socket A3 will be thinner due to It is thin and easy to break when subjected to external force collisions. In particular, users often make the connector plug A1 insert or pull out the connector socket A3 at a slightly inclined angle due to operating habits or operating angles. The side wall of the connector receptacle A3 (i.e., the side wall corresponding to the keyway A34) is damaged due to excessive stress

[0006] Second, continue to see Figure 1B and Figure 1C As shown, since there are almost no additional structures (such as: ribs) on the inner wall of the side wall of the aforementioned connector socket A3 (that is, the side wall corresponding to the keyway A34), therefore, in production (especially for miniaturized connectors) case), the side wall of the aforementioned connector socket A3 is likely to be uneven, resulting in the failure of the connector socket A3 and the connector plug A1 to be smoothly plugged together, resulting in an increase in the defective rate of the connector socket A3

Although Figure 1C In addition, a positioning part A38 will be added outside the side wall of the connector socket A3, so that the separate positioning part A5 can be placed in the positioning part A38, and the side wall of the aforementioned connector socket A3 can be improved through the positioning part A38. Wall strength, in addition, with the influence of thinner and lighter connectors, many connector sockets A3 have canceled the structure of the positioning part A38, so as to reduce the volume of the connector socket A3. Wall problems (easy to be damaged by external force, easy to be uneven during production) are more obvious

[0007] Finally, continue to see Figure 1A As shown, the length of the key A13 is almost flush with the length of the barrel A12, and the key A13 is located away from the rest of the barrel A12, therefore, as Figure 1C As shown, the key A13 is equivalent to being exposed outside the connector plug A1 as a whole. This design method will cause the key A13 to be easily damaged by collisions with foreign objects. The key A13 is used as a fool-proof structure, so when the key A13 is damaged and broken, the fool-proof structure of the connector element in the prior art will fail, making it impossible for the user to know whether the current insertion direction is correct
