Description

  The present invention relates to the improvement of the terminal stability structure of a connector, and more particularly to the design improvement of the connector applied to a transmission interface such as HDMI or USB.

A conventional USB connector or HDMI connector is usually provided with a connection seat 101 at the connecting end of the insulating connector body 10 (shown in FIG. 12), and a plurality of parallel connections are provided on one or two surfaces of the connection seat 101. A terminal groove 102 is provided, and the terminal groove 102 penetrates to the bottom end of the connector body 10. Thereby, the conductive terminal 20 is implanted in each terminal groove 102, a part of the contact end 201 of the conductive terminal 20 is exposed on the terminal groove 102, and the welding stage is positioned at the bottom end of the connector body 10. To do. In this manner, when another connector combined with each other is inserted and connected, an electrical connection can be formed through contact with the conductive terminal 20.
The combination structure of the terminal groove 102 and the conductive terminal 20 exposes the contact end 201 and is higher than the surface of the connection seat 101. Therefore, when another connector at the cable end is inserted, the conductive terminal 20 is inserted. The contact end 201 tends to be bent or deformed (shown in FIG. 13), or the entire conductive terminal 20 is pressed and released (generally referred to as “pin disengagement”), thereby leading to damage to the connector. As can be seen from this, it is necessary to improve the conventional connector combination structure in order to increase the quality stability and practicality.

The main purpose of the present invention is to improve the structure of the connecting body of the insulating body of the connector and the structure of the conductive terminal, so that the conductive terminal can be securely and securely coupled to the connection base, and the conductive terminal is pressed and bent in the process of plugging connection. An object of the present invention is to provide an improved terminal stability structure of a connector that prevents deformation or disconnection (pin disengagement), avoids damage to the connector, and achieves effects such as quality stability.
For this purpose, the implementation of the present invention is composed of at least one insulating body and a plurality of conductive terminals, and a shielding shell is provided outside the insulating body, of which at least one is selected on the selection side of the insulating body. A connection seat is provided, a plurality of terminal grooves arranged on one or both sides of the connection seat are provided, and a fitting groove is provided on a groove end wall approaching the connection port end of each terminal groove. A contact block is formed on the upper side, and the conductive terminal is formed of a connection step and a welding step, and in particular, a fixed piece is provided at the end of the connection step. As a result, the conductive terminal is implanted in the terminal groove of the connection seat so that the fixed piece at the end is fitted in the fitting groove close to the end of the connection port, and the pressing of the contact block prevents the fixed piece from warping up. Thus, the function of preventing the conductive terminal from being bent or detached is achieved, and the quality of the connector becomes more stable and practical.

  This is an improvement of the terminal stability structure of the connector, which is a connector applied to an HDMI or USB transmission interface, and is mainly composed of an insulating body and a plurality of conductive terminals. There are two connection seats, a plurality of terminal grooves are provided on one or both sides of the connection seat, a fitting groove is provided on the groove end wall approaching the connection port end of each terminal groove, and other conductive terminals are connected. A fixed piece is provided at the end of the step, so that if the conductive terminal is assembled in the terminal groove of the connection seat, the fixed piece is inserted into the fitting groove, and the conductive terminal can be stably assembled. Achieved.

As shown in the figure, the “improvement of the terminal stability structure of the connector” performed in this embodiment is composed of an insulating body 1 and a plurality of conductive terminals 2, and a shielding shell 3 is attached to the outside of the insulating body 1. Also good.
The insulating body 1 is configured as a rectangular or other shape base (shown in FIGS. 1 and 2), and at least one connection seat 11 is provided at a selected location close to the end of the connection port. A plurality of arranged terminal grooves 12 are provided on the surface (shown in FIGS. 4 to 6), and a concave groove 121 is provided in parallel at the center of the bottom surface of the terminal groove 12. A stepped support surface 122 is formed as a support portion of the conductive terminal 2 described below, and the concave groove 121 is extended to the groove end wall near the connection port end of the terminal groove 12 to be connected to the connection port end of the terminal groove 12. A fitting groove 13 is formed on the near groove end wall, and a contact block 14 is formed on the upper side of each fitting groove 13. The other end of each terminal groove 12 penetrates to the bottom of the insulating body 1 (shown in FIG. 10).

  The conductive terminal 2 is implanted as a connection medium in the insulating body 1 (shown in FIGS. 1 and 2), and each conductive terminal 2 is a needle-like terminal configured to include a connection stage 21 and a welding stage 22. The end portion 211 of the connection step 21 is bent into a fixed piece 23 by pressing (shown in FIGS. 8 and 9), and the structure of the fixed piece 23 includes an arc-shaped portion 231, and the arc-shaped portion 231. Is connected to the end portion 211 of the connection step 21, and the arc-shaped portion 231 is bent to one side surface 236 to form a fitting lump 232 parallel to the connection step 21 at the other end of the arc-shaped portion 231. 232 protrudes forward to form a step difference in height with the connection step 21, and a slope guide angle 237 having a slope is formed at the adjacent portion of the front end face 233 and the two side edges 234 of the fitting mass 232. Further, the width (including the arc-shaped portion 231 and the fitting lump 232) separated by the two side edges 234 of the fixed piece 23 is smaller than the width separated by the two side edges 212 of the connection stage 21. 21 forms a step with a width, and the fixing piece 23 constitutes a structure that can be combined with the fitting groove 13. The welding stage 22 at the other end of the conductive terminal 2 may be bent or configured in another shape, and is not particularly limited. Further, the selected side 212 of the conductive terminal 2 may be provided with a protrusion 24 that is a structure that prevents the insulation body 1 from being fixed and dropped off.

As a result, the conductive terminal 2 is implanted in the terminal groove 12 of the connection seat 11 of the insulating main body 1, and the protrusions 24 are inserted and fixed to both side groove walls, and the connection step 21 is coupled to the terminal groove 12 and the support surface 122. Therefore, a stable support and covering structure is formed by the two support surfaces 122 and the groove wall, and the connection step 21 is made slightly higher than the terminal groove 12 to be a connection point. Further, the fitting lump 232 of the fixed piece 23 is fitted into the fitting groove 13 close to the end of the connection port (shown in FIGS. 7, 10, and 11) by the step structure of the height and the width (shown in FIGS. By using this, the fitting lump 232 of the fixing piece 23 is pressed to prevent the entire conductive terminal 2 from being warped and the arc-shaped portion 231 is used as a guide surface so that another connector at the cable end can be more easily inserted. Further, since the welding stage 22 is exposed at the bottom of the insulating body 1, it can be assembled and welded to a circuit board (PCB) or the like.
The shielding shell 3 is a hollow metal shell (shown in FIGS. 1 and 3) and is configured to be attached to the outside of the insulating main body 1. A fastening piece 32 is provided at the connection port end 31, and the connection port A plurality of connection pieces 33 are provided at the end opposite to the end 31. Thus, whether or not the shielding shell 3 is assembled is determined according to specific needs, and if the shielding shell 3 is attached to the outside of the insulating body 1, the periphery of the connection seat 11 is shielded.

  In the improvement of the terminal stability structure of the connector of this embodiment, the fitting lump 232 of the fixing piece 23 of the conductive terminal 2 and the fitting groove 13 of the terminal groove 12 are coupled (shown in FIGS. 7 and 11), thereby fitting grooves. Since the upper contact block 14 presses the fitting block 232 of the fixed piece 23, such an assembly structure design prevents a phenomenon such as warping or bending that occurs when the connection stage 21 is connected, and also the fixed piece 23. By using the arc-shaped portion 231 as a guide surface, another connector at the end of the cable can be inserted more easily, and damage to the conductive terminal 2 can be avoided. Further, the function of preventing the conductive terminal 2 from being detached or loosened is achieved in accordance with the structure in which the protrusion 24 is inserted and fixed to the groove wall of the terminal groove 12. As described above, the present invention improves the defects that are easily damaged by the poor assembly structure of the conventional connector, and achieves the effect of stabilizing the quality of the connector, which is particularly effective for the current mainstream USB interface or HDMI connector.
