Description

Technical Field

[0001] The utility model relates to an anti-foolproof structure for an electric connector, and more particularly to a structure in which an interference portion is protruded on each terminal at the two outermost sides of a terminal group in an insulating seat body by means of a new mold technology and a stamping process, so that when an external electric connector is inserted, it is blocked by the interference portion and cannot be inserted further, and no additional anti-foolproof components are required, so as to achieve the purpose of saving assembly time and money. Background Art

[0002] With the advancement of computer technology today, desktop computers, laptops and other devices have gradually become part of people's lives. With the development of the Internet, people can obtain and search for information online through various electronic devices, and can also perform online tasks through the Internet, making the use of the Internet inseparable from life and work.

[0003] In order to effectively transmit the network, the connection of the wired network can be more stable than the use of the wireless network. The plugs used for the wired network can be divided into RJ-11 plugs (REGISTERED JACK-11) and RJ-45 plugs (REGISTERED JACK-45). Among them, the RJ-11 plug is mostly used in telephones and fax machines, and the number of pins of the terminal is usually around 2 to 4, while the RJ-45 plug is mostly used in computer network connections and mainly provides 8-pin terminals. Although the two types use different devices, they are similar in appearance, which is easy to cause users to insert them incorrectly, thereby causing the connector to be skewed, twisted, deformed, and damaged due to the incorrect insertion. In addition, the design of a fool-proof structure in the connector to prevent incorrect insertion requires additional assembly cost and time, which is the key point that those engaged in this industry are eager to study and improve.

DETAILED DESCRIPTION

[0023] See also Figures 1 to 4 As shown, they are a three-dimensional appearance diagram, a three-dimensional appearance diagram from another perspective, a three-dimensional exploded diagram and a three-dimensional exploded diagram from another perspective of the utility model electrical connector foolproof structure. The utility model electrical connector foolproof structure mainly includes an insulating seat body 1, a terminal group 2 and a shielding shell 3, and the connection relationship of the above-mentioned components is as follows:

[0024] A plug-in space 10 is formed inside the insulating seat body 1, and a docking port 11 for an RJ-45 type electrical connector (not shown) to electrically dock is provided on one side of the plug-in space 10, and a plurality of terminal holes 12 that pass through to the outside of the insulating seat body 1 are provided on the side opposite to the docking port 11 of the plug-in space 10, and a plurality of terminal grooves 121 extend from the bottom of the plug-in space 10 toward the docking port 11, and a plurality of interference protrusions 13 that are respectively aligned with the plurality of terminal grooves 121 are protruded between the docking port 11 and the plurality of terminal grooves 121, and each of the interference protrusions 13 extends obliquely toward the docking port 11 with an inclined surface 131, and a notch 111 is provided on the top surface of the insulating seat body 1 toward the docking port 11, and a plurality of positioning blocks 14 are provided outside the insulating seat body 1.

[0025] The terminal group 2 has a plurality of terminals 21 respectively penetrated in the insulating base body 1 and positioned in the plurality of terminal slots 121, and each of the terminals 21 has a main body 211, and one side of the main body 211 is provided with a welding portion 212 that penetrates out of the insulating base body 1 through the plurality of terminal holes 12, and the other side of the main body 211 is provided with an interference surface 2131 that is tilted at an angle after being folded back, and the interference surface 2131 continues to extend obliquely upward to have a contact portion 213 in the insertion space 10, and an interference portion 2111 is protruded from each of the main bodies 211 of the terminals 21 on the two outermost sides of the terminal group 2, and a guide surface 2112 is extended obliquely toward the docking port 11 at each of the interference portions 2111.

[0026] The shielding shell 3 covers the outside of the insulating base 1, and the surface of the shielding shell 3 is provided with an opening 30 aligned with the docking port 11, and a limiting groove 301 corresponding to the notch 111 extends from the top surface of the opening 30, and the outside of the shielding shell 3 is provided with a plurality of positioning grooves 31 corresponding to the positioning blocks 14.

[0027] At least one side of the top surface of the insulating base body 1 is provided with a receiving portion 15 for receiving a light-emitting element 16 (such as a light-emitting diode), and the receiving portion 15 is provided with a plurality of second terminals 161 for extending the light-emitting element 16 and passing through a plurality of through holes 150 outside the insulating base body 1, so that the light and flashing of the light-emitting element 16 can be used to identify the plugging state of the electrical connector of the utility model.

[0028] When the foolproof structure of the electrical connector of the utility model is to be constructed, the main bodies 211 of the plurality of terminals 21 of the terminal set 2 are respectively inserted into the plurality of terminal slots 121 of the insulating seat 1, and the welding portions 212 extending from one side of the plurality of terminals 21 are inserted out of the insulating seat 1 through the plurality of terminal holes 12, and the contact portions 213 extending from the other side of the plurality of terminals 21 in a curled shape are extended into the plug-in space 10, and then at least one of the light-emitting elements 16 is accommodated in the plurality of terminals 21. After the plurality of second terminals 161 extending from the light-emitting element 16 are inserted into the accommodating portion 15 of the insulating seat body 1 through the plurality of through holes 150 and out of the insulating seat body 1, the shielding shell 3 can be covered on the outside of the insulating seat body 1 so that the opening 30 is aligned with the docking port 11, and the positioning grooves 31 on the outside of the shielding shell 3 are correspondingly inserted into the corresponding positioning blocks 14 on the outside of the insulating seat body 1 for positioning, thereby completing the overall structure of the fool-proof structure of the electrical connector of the utility model.

[0029] Please continue reading Figure 5 , Figure 6, respectively, are schematic side cross-sectional views of the connector insertion front and rear side cross-sectional views of the utility model electrical connector fool-proof structure. It can be clearly seen from the figure that the utility model electrical connector fool-proof structure is an electrical connector that complies with the RJ-45 specification, and has a fool-proof structure inside that prevents an RJ-11 type electrical connector 4 from being inserted, so that the RJ-11 type electrical connector 4 is extended into the plug-in space 10 from the mating interface 11 of the insulating seat body 1, and the RJ-11 type electrical connector 4 has only 6PIN terminals, so that the terminals 21 on the outermost two sides of the terminal group 2 of the electrical connector corresponding to the RJ-45 specification in the insulating seat body 1 are in contact with the chassis on both sides of the RJ-11 type electrical connector 4 to form a dry Involved, and because the chassis on both sides of the RJ-11 type electrical connector 4 is higher than the internal terminals (not shown in the figure), after extending into the plug-in space 10 of the insulating seat body 1, it will be supported by the interference protrusion 13 for horizontal displacement, and the chassis on both sides of the RJ-11 type electrical connector 4 will press the multiple terminals 21 downward, so that the interference surface 2131 and the obliquely extended contact portion 213 are pushed to move downward and abut against the interference portion 2111 to form a blockage, thereby making the RJ-11 type electrical connector 4 unable to be inserted into the plug-in space 10 due to the blocking and interference of the interference surface 2131 and the interference portion 2111 during plugging, thereby achieving the anti-foolproof effect of preventing the RJ-11 type electrical connector 4 from being inserted.

[0030] Furthermore, the terminal set 2 is designed to protrude the interference portion 2111 on each of the terminals 21 on both sides through new mold technology and stamping technology, so that the RJ-11 type electrical connector 4 is blocked by the interference portion 2111 when being inserted and cannot be inserted further, while a normal RJ-45 type electrical connector will pass through the protruding interference portions 2111 and be inserted normally. This design can be achieved through the normal assembly of the terminal set 2, so there is no need to install the old-fashioned additional anti-fool components, thereby achieving the purpose of saving assembly time and money.

[0031] In addition, the utility model is mainly aimed at each terminal 21 of the terminal group 2 arranged in the insertion space 10 of the insulating seat body 1, and each terminal 21 has an interference surface 2131 that is tilted at an angle after being folded back, and each of the main bodies 211 of the terminals 21 on the two outermost sides of the terminal group 2 is protruding with an interference portion 2111, and then each terminal is pressed downward by pushing and deforming, so that the interference surface 2131 and the interference portion 2111 form interference and obstruction, so as to prevent the RJ-11 type electrical connector 4 from being inserted incorrectly.

[0032] The above description is only a preferred embodiment of the present utility model, and does not limit the patent scope of the present utility model. Therefore, all simple modifications and equivalent structural changes made by using the contents of the present utility model specification and drawings should be included in the patent scope of the present utility model and are hereby stated.
