Background Art

[0002] Computer technology is growing at a rapid pace today, and the development trend of computers is also moving towards powerful computing functions, fast speed and small size, which has reduced the number of computer communication ports. Such communication ports may also be used in other devices with the same specifications, such as car audio, car computer, charging device, satellite navigation, communication device, etc. However, in addition to sockets, the communication ports in these devices are cable plugs that combine cables and plugs. Therefore, the future development of such cable plugs is also rising. However, the size of such cable plugs is getting smaller and smaller. How to use a good structural design in the overall structural configuration so that the cable plug will not directly pull the cable when plugging and unplugging? In order to prevent the occurrence of such a situation, it is also necessary to avoid the situation where the cable plug and the socket connector are too small and easily damaged. In addition, in the absence of any supporting or fixed structure for the plug, it is easy for the cable plug to be pulled and fall off after being inserted into the socket, thereby affecting the transmission of the signal. Therefore, it can be found from the above detailed description that in the design of the cable plug, the stability of the cable plug when docking with the socket connector can be the main consideration. In addition, it should be noted that the plug is exposed when connected to the cable, and the situation of pulling the wire to cause the plug to be detached should be avoided during use. Therefore, in view of the above-mentioned conventional deficiencies, it is necessary for relevant industries to conduct additional research and development to improve the deficiencies and deficiencies of the existing technology.

[0039] Furthermore, when assembling the present invention, the pull belt 4 is first wound and fixed at the position of the through hole 2101 of the sliding seat 2, and then the body 21 of the sliding seat 2 is placed on the mounting surface 112 of the seat body 11, and at the same time, the track holes 2110 of the track pieces 211 on both sides of the body 21 are limitedly sleeved on the convex rails 1132 to be positioned, and the elastic parts 22 integrally formed on both sides of the rear of the body 21 are suspended at the ends thereof against the stopper 1121 of the mounting surface 112, and then the pressing surface 31 of the buckle assembly 3 is placed on the mounting surface 112 and located behind the body 21 of the sliding seat 2, and the rotating parts 33 of the two arms 32 are pivoted to the mounting surface 112. The positioning part 113 is then positioned between the pivoting part 1133 of the positioning part 113 and the limiting shaft part 123 of the shell 12, and the hook parts 321 of the two arms 32 and the supporting spring pieces 322 below are installed at the limiting parts 1131. The fixed space 120 in the center of the shell 12 is inserted into the relatively concave limiting groove 121 from the docking part 111, so that the limiting shaft part 123 is placed in the rotating part 33 and is sleeved on the pivoting part 1133 for positioning, and the engaging part 114 of the seat body 11 passes through the engaging hole 124 of the shell 12 for an engaging positioning, and at the same time, the two hook parts 321 are located in the positioning part The limiting portion 1131 of 113 passes through the through hole 122 on the upper plate surface of the shell 12. At this time, the supporting spring piece 322 is supported downwardly against the bottom surface of the limiting portion 1131 to form an upward elastic pre-force holding state of the hook portion 321 supporting the two arms 32, so as to form an unformed state before the mutual combination of the seat body 11, the sliding seat 2, the buckle assembly 3 and the shell 12, and the contact group 102 of the circuit board 10 is welded with the wire 13, and the docking terminal group 101 of the circuit board 10 is continuously pushed into the rear side direction of the accommodating space 110 of the seat body 11, and the docking terminal group 101 of the circuit board 10 extends out A positioning is formed at the docking portion 111 of the seat body 11. At this time, an insulating colloid 5 is integrally formed at the rear of the accommodating space 110 of the seat body 11, so that the contact group 102 of the circuit board 10 and the wire 13 located at the contact group 102 are covered with the insulating colloid 5, so that the circuit board 10 is stably fixed in the accommodating space 110 of the seat body 11, and the fixing hole 125 of the molded shell 12 is combined with the insulating colloid 5, thereby combining the shell 12 and the circuit board 10 welded with the wire 13 with each other through the insulating colloid 5 to be firmly covered and joined to the seat body 11, thereby completing the overall structure of the plug connector of the present invention.

[0040] Please continue reading Figures 1 to 4 As shown in the figure, it can be clearly seen that the socket connector 6 is welded on a circuit board 7, and the upper plate surface on both sides of the plug-in portion 61 of the socket connector 6 is provided with snap-fit ​​holes 62 for the hook portions 321 of the two arms 32 to be snapped into and positioned.

[0041] Please continue reading Figure 2 , Fig.10As shown in the figure, it can be clearly seen that when locking, the present invention first inserts the docking portion 111 of the plug connector of the present invention into the plug-in portion 61 of the socket connector 6 to form an electrical connection. At this time, the two retaining springs 322 are supported downward against the bottom surface of the limiting portion 1131, and the hook portions 321 of the two arms 32 are in an upward elastic pre-forced retention state and are snapped into the locking hole 62 to form a positioning.

[0042] Please continue reading Fig.10 As shown in the figure, it can be clearly seen that the present invention has two unlocking methods. The first unlocking method is to press the pressing surface 31 of the buckle assembly 3, that is, the rotating part 33 can be used as the axis point to make the supporting spring piece 322 support downward against the bottom surface of the limiting part 1131 and elastically deform, and the pressing surface 31, the two arms 32 and the hook part 321 of the buckle assembly 3 are elastically offset downward by a distance in the space of the installation surface 112. At this time, the two hook parts 321 are detached from the buckling holes 62 of the plug-in part 61 of the socket connector 6 and fall into the through hole 122 of the shell 12, even if the plug connector of the present invention can be easily detached from the electrical connection of the socket connector 6, and the second method is to pull the drawstring 4 at the through hole 2101 to make the elastic part 22 of the sliding seat 2 at the installation surface 112 The extrusion elastic deformation is generated, and the pushing portion 210 pushes the pressing surface 31 so that the two arms 32 and the hook portions 321 are elastically offset downward by a distance in the space of the mounting surface 112, and the two hook portions 321 can be separated from the buckling holes 62 of the plug-in portion 61 of the socket connector 6 and fall into the through holes 122 of the shell 12. This method can also make the plug connector easily detach from the electrical connection of the socket connector 6, and reuse the insulating colloid 5 that combines the shell 12, the seat body 11 and the circuit board 10 welded with the wire 13 into a stable state, and assist in the plug connector of the present invention to be withdrawn from the socket connector 6 to prevent the shell 12, the circuit board 10 or the wire 13 from detaching from the seat body 11 of the connector 1 in the withdrawal direction, thereby causing poor contact, connection failure, etc.

[0043] Furthermore, please continue to read Figure 3 , Figure 4 , Fig.10As shown in the figure, it can be clearly seen that the two sides of the pressing surface 31 of the present invention are respectively extended in the same direction with support arms 32 and a supporting spring piece 322 is provided below to support the support arm 32 upward. The two support arms 32 are arranged in an aligned and spaced manner with the hook portion 321 and the supporting spring piece 322 up and down, so that when the two supporting spring pieces 322 elastically support downward against the bottom surface of each limiting portion 1131, the hook portion 321 of the two support arms 32 above the two supporting spring pieces 322 can stably generate a vertical upward elastic pre-force holding state. However, the two supporting spring pieces 322 only need to have the hook portion 321 of the two support arms 32 to maintain a vertical upward elastic pre-force when the pressing surface 31 is not touched or the drawstring 4 is not pulled. The simple and equal change and modification of the position of the two supporting spring pieces 322 does not limit the protection scope of the present invention.

[0044] In addition, in a preferred embodiment of the present invention, an elastic portion 22 with a continuous turning S-shaped spring piece is integrally formed on the two rear sides of the main body 21 of the sliding seat 2. However, the number of the elastic portion 22 can be at least one so that the sliding seat 2 can form a sliding state on the seat body 11 through the elastic portion 22 with telescopic displacement, and the S-shaped spring piece integrally formed with the elastic portion 22 can be in a "Z" shape or an "8" shape, or the elastic portion 22 can be formed by an extended spring piece on the sliding seat 2. Therefore, the elastic portion 22 only needs to have a shape with elastic deformation and reset functions. This simple equalization and modification does not limit the protection scope of the present invention.

[0045] In addition, in the present embodiment, the center of the docking portion 111 of the connector 1 is provided with a docking terminal group 101 of the circuit board 10, so that the docking terminal group 101 can be used as an electrical connection with the socket connector 6. Therefore, the docking terminal group 101 of the circuit board 10 in the connector 1 is not necessarily designed in the form of a circuit board, but can also be designed in the form of other multiple terminals or conductive sheets to be used as a cable connector of a plug or socket combined with a cable. Such simple equal changes and modifications do not limit the protection scope of the present invention, and such simple equal changes and modifications should still be included in the patent scope covered by the present invention.

[0046] In addition, in the present embodiment, the rotating portion 33 of the snap assembly 3 of the connector 1 is combined with the pivot portion 1133 of the seat body 11, and the shell 12 is assembled on the seat body 11, so that the limit shaft portion 123 of the shell 12 is assembled at the pivot portion 1133 so that the snap assembly 3 forms an axial limit and is in a pivotal state of swinging with the pivot portion 1133 as the axis. The snap assembly 3 can also be independently assembled on the pivot portion 1133 of the seat body 11 or on the limit shaft portion 123 of the shell 12 in a swinging state. Such simple equal changes and modifications do not limit the protection scope of the present invention, and such simple equal changes and modifications should still be included in the patent scope covered by the present invention.

[0047] In addition, the present invention is mainly aimed at the pressing surface 31 when being pressed, so that the supporting spring piece 322 can be elastically deformed to link the hook portion 321 of the two supporting arms 32 to be offset downward by a distance, and when the pull belt 4 pulls the sliding seat 2 to elastically deform the elastic portion 22, the hook portion 321 of the two supporting arms 32 can also be elastically offset downward, and an insulating colloid 5 is integrally formed at the rear of the accommodating space 110 of the seat body 11 to fix the circuit board 10 in the seat body 11, and at the same time, its shell 12, circuit board 10 and wire 13 are combined with each other to form a stable covering joint with the seat body 11, which is its main feature, thereby achieving the effect of forming a stable docking and reliable action of the plug connector on the corresponding socket connector 6, and when the thin and smaller plug connector is plugged in and out, the insulating colloid 5 integrally formed on the plug connector is used to prevent the contact of its shell 12, circuit board 10 or wire 13 from peeling or shaking, thereby achieving the effect of ensuring the electrical connection of the plug connector and preventing damage.

[0048] The above detailed description is only for a preferred feasible embodiment of the present invention, and the embodiment is not used to limit the scope of the claims of the present invention.
