The invention relates to a plug connector buckle release mechanism, and in particular to a plug connector provided with a buckle device and a casing for releasing on a corresponding socket connector through a pull strap to form a stable docking and easy separation operation.
Nowadays, computer technology is developing at a rapid pace, and the development trend of computers is also moving towards strong computing power, fast speed and small size, and the number of computer communication ports is also reduced. This kind of communication ports can also be used with other devices with the same specifications, such as car audio, car computers, charging devices, satellite navigation, communication devices, etc. However, these devices contain communication port plugs, so the future development of such plugs with communication ports is also on the rise. However, with the improvement of technology in recent years, the size of plugs has become smaller and smaller. In terms of overall structural configuration, how to use good structural design to prevent the plug from directly pulling on the internal cable when plugging and unplugging, and to avoid the plug and socket connector being too small and easily damaged. In addition, without any support or fixed structure for the plug, it is easy for the plug to be pulled and fallen off after being inserted into the socket, thus affecting the signal transmission. Therefore, from the above detailed description, it can be found that when designing the plug, the main consideration can be to ensure the stability of the plug when docking with the socket connector. During the use of the plug, it should be avoided pulling on the wire to cause the plug to detach. Therefore, in view of the shortcomings of the above-mentioned conventional designs, it is necessary for relevant industries to conduct additional research and development to improve the shortcomings of the conventional designs.
Therefore, in view of the above-mentioned problems and deficiencies, the inventor collected relevant information, evaluated and considered many aspects, and used his many years of experience in this industry to design this kind of plug connector buckle release mechanism and the matching socket connector.
It is therefore the main object of the present invention to provide a plug connector buckle release mechanism comprising a connector, a buckle device and a casing. The connector comprises a base block and a mating terminal set mounted in the base block. The base block comprises a docking portion formed on a front side thereof and a mounting surface formed on an upper surface thereof at a rear side relative to the docking portion. The buckle device comprises a base slidingly installed on the mounting surface, two arms located on two opposite lateral sides of the base and extending in the same direction toward the docking portion. Each arm comprises a hook portion protruding upward from a suspended distal end thereof remote from the base, and a stepped push portion located on a top side thereof. The elastic portions with narrow longitudinal width are provided on the two sides of the base toward the front where the two arms are connected, two resisting portions bilaterally located on a bottom side of the base, and a pull strap combined with the base. The casing covers the base block. The casing comprises two through holes bilaterally located on a top surface thereof corresponding to the docking portion, two push portions bilaterally provided on an inner wall thereof and extending to a rear side of the stepped push portions, a beveled guide surface provided on the bottom of the push portions, and two elastic members respectively and integrally formed on the inner wall of the casing toward a rear side and extending downward and then obliquely bent toward the two opposite lateral sides of the casing. When pulling the pull strap, the buckle device makes the resisting portions displace and push against the elastic members to form elastic deformation, causing the stepped push portions of the two arms can be laterally limited by the push portions to elastically deflect downwards, so that the hook portions of the two arms are linked to elastically deflect downwards at the through holes.
It is another object of the present invention to provide a plug connector buckle release mechanism and a matching socket connector. The plug connector buckle release mechanism comprises a connector, a buckle device and a casing. The connector comprises a base block and a mating terminal set mounted in the base block. The base block comprises a docking portion formed on a front side thereof and a mounting surface formed on an upper surface thereof at a rear side relative to the docking portion. The buckle device comprises a base slidingly installed on the mounting surface, two arms located on two opposite lateral sides of the base and extending in the same direction toward the docking portion. Each arm comprises a hook portion protruding upward from a suspended distal end thereof remote from the base, and a stepped push portion located on a top side thereof. The elastic portions with narrow longitudinal width are provided on the two sides of the base toward the front where the two arms are connected, two resisting portions bilaterally located on a bottom side of the base, and a pull strap combined with the base. The casing covers the base block. The casing comprises two through holes bilaterally located on a top surface thereof corresponding to the docking portion, two push portions bilaterally provided on an inner wall thereof and extending to a rear side of the stepped push portions, a beveled guide surface provided on the bottom of the push portions, and two elastic members respectively and integrally formed on the inner wall of the casing toward a rear side and extending downward and then obliquely bent toward the two opposite lateral sides of the casing. When the docking portion of the connector of the present invention is inserted into the socket portion of the matching socket connector to form an electrical connection, the stepped push portions of the two arms are located on the front side of the push portions of the casing, and the hook portions of the two arms are maintained in an elastic pre-forced state and snap into respective positioning snap holes of the matching socket connector to form positioning. When pulling the pull strap to unlock, the buckle device makes the resisting portions displace and push against the elastic members to form elastic deformation, causing the stepped push portions of the two arms can be laterally limited by the push portions to elastically deflect downwards. At this time, the two hook portions are detached from the positioning snap holes of the matching socket connector and lowered into the through holes of the casing, so that the connector of the plug connector buckle release mechanism of the present invention can be easily detached from the electrical connection of the matching socket connector.
Still another object of the plug connector buckle release mechanism of the present invention is that the inner side of the casing is provided with the push portions on both lateral sides that extend forward to the rear side of the stepped push portions and then bend downward at an angle, and a curved surface is formed at the bottom of each push portion. When the pull strap is pulled to unlock, the stepped push portions of the two arms can be laterally limited by the push portions and move over the push portions along the curved surfaces to be placed under the push portions to form downward elastic deformation, so that the hook portions of the two arms are linked to elastically deflect downward at the through holes.
In order to achieve the above objects and effects, the technical means and structures adopted by the present invention are described in detail below with respect to the preferred embodiment of the present invention in companying with the drawings, so as to facilitate a complete understanding.

In addition, in the embodiment of the present invention, two elastic members 35 are respectively and integrally formed on the inner wall of the casing 3 toward the rear side and extending downwards and are obliquely bent toward the two lateral sides of the casing 3. However, the number of the elastic members 35 can be set to at least one. The casing 3 can use the elastic members 35 with elastic displacement to make the buckle device 2 form a limited slip state. The elastic members 35 extending obliquely can also be a continuously bent shape. Therefore, the elastic members 35 only need to be in a state of the elastic deformation and reset function. Such simple equivalent changes and modifications do not limit the scope of protection of the present invention, and are hereby stated.
In addition, in the embodiment of the present invention, the center of the docking portion 111 of the connector 1 is a circuit board-type mating terminal set 12, so that the mating terminal set 12 can be used as an electrical connection with the matching socket connector 4. Therefore, the mating terminal set 12 in the docking portion 111 of the connector 1 is not necessarily designed in the type of a circuit board 5, but can also be designed as a cable-connected plug or socket in the form of other a plurality of terminals or conductive sheets. Such simple equivalent changes and modifications do not limit the scope of protection of the present invention. Such simple equivalent changes and modifications should still be included in the patent scope covered by the present invention.

In addition, the push portions 34 of the first embodiment and the second embodiment of the present invention extend into the grooves 114 for the stepped push portions 223 of the two arms 22 to touch and move over the push portions 34 to be placed below the push portions 34, so that the two arms 22 of the buckle device 2 are elastically deflected downward by a distance on both sides of the base block 11 through the elastic portions 222 as the fulcrum. The push portions 34 can also be protrusions formed on the inner wall of the casing 3 and extending into the grooves 114, or protrusions can be protrusions on the two sides of the base block 11 and protruding from the stepped push portions 223 of the two arms 22 to provide the designs of the elastic deformation and reset function for the stepped push portions 223 of the two arms 22. Moreover, by extending the push portions 34 into the grooves 114, the contact area of the stepped push portions 223 is increased, so as to prevent the two arms 22 from being skewed during operation to cause inaccurate movement. Therefore, the push portions 34 do not necessarily need the design of the grooves 114, and can also be directly pressed against the two lateral side surfaces of the base block 11. Such simple equivalent changes and modifications do not limit the scope of protection of the present invention. Such simple equivalent changes and modifications should still be included in the patent scope covered by the present invention.
In addition, the stepped push portions 223 are provided between the hook portions 221 and the elastic portions 222 of the buckle device 2 and at the top side of the two arms 22. The stepped push portions 223 can also be in the form of protrusions or inclines, so that when actuating, they resist the push portions 34 to link the two arms 22 to produce displacement, so that the two arms 22 form the elastic deformation and reset function. Moreover, the elastic portions 222 with narrow longitudinal width are provided on the two sides of the base 21 toward the front where the two arms 22 are connected. The elastic portions 222 can also be set in a lateral bending or other forms to make the two arms 22 can elastically deflect downward by a distance on both sides of the base block 11 through the elastic portions 222 as a fulcrum, so that the two arms 22 can form the elastic deformation and reset function. Such simple equivalent changes and modifications do not limit the scope of protection of the present invention. Such simple equivalent changes and modifications should still be included in the patent scope covered by the present invention.
In addition, when the first and second embodiments of the present invention are unlocked multiple times, if the pull strap 25 is detached or broken at the joint, a flat preset hand tool or any preset tools can be used and inserted into the opening 24 and pushed backward, the same unlocking action as pulling the pull strap 25 can be produced to separate the connector 1 from the electrical connection of the matching socket connector 4.
In addition, the present invention is mainly aimed at pulling the pull strap 25, so that the two arms 22 of the buckle device 2 can move over the push portions 34 of the casing 3 to produce a downward elastic deflection, and the hook portions 221 of the two arms 22 can be elastically deflected downward by a distance, which is a main feature of the present invention. This achieves the effect of the base block 11 of the connector 1 forming a stable connection with the matching socket connector 4 and ensuring accurate action.
The above description is only the preferred embodiments of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the description and drawings of the present invention shall be included in the patent scope of the present invention and shall be clearly stated.
To sum up, when the plug connector buckle release mechanism and the matching socket connector of the present invention are used, they can indeed achieve their effects and purposes. Therefore, the present invention is truly an invention with excellent practicality.
