DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0026] like Figures 1 to 6 As shown, a wire-to-board connector described in this embodiment includes a board-end connector and a wire-end connector;

[0027] The board-end connector comprises a board-end body 11, the board-end body 11 has a plug-in cavity 12, the board-end body 11 is provided with a through hole 13 on a side facing away from the opening of the plug-in cavity 12, and a first clamping platform 14 is provided on the inner top wall of the plug-in cavity 12 at a position corresponding to the through hole 13;

[0028] The wire end connector includes a wire end body 21 , a pressing tongue plate 22 is disposed on the top of the wire end body 21 , and the pressing tongue plate 22 is provided with a second clamping platform 23 for clamping connection with the first clamping platform 14 .

[0029] Specifically, in this embodiment, when the board-end connector and the line-end connector are plugged in, pressure is applied to the pressing tongue plate 22 so that the second clamping platform 23 enters the plug-in cavity 12 until the second clamping platform 23 passes over the first clamping platform 14, and then the pressure on the pressing tongue plate 22 is released, so that the second clamping platform 23 and the first clamping platform 14 form a snap fit, and the board-end connector and the line-end connector are locked, thereby effectively preventing the line-end connector from withdrawing from the plug-in cavity 12, and ensuring the reliability of the electrical plug-in of the board-end connector and the line-end connector;

[0030] When the board-end connector and the line-end connector need to be electrically connected, pressure is applied to the pressing tongue plate 22 and then the line-end connector is pulled out.

[0031] In this embodiment, a through hole 13 is provided on the side of the board end body 11 facing away from the opening of the plug-in cavity 12, so that a first clamping platform 14 can be provided on the top wall of the plug-in cavity. When plugging in, the board end connector and the wire end connector are locked by the snap connection between the first clamping platform 14 and the second clamping platform 23. Such a setting is conducive to the development of connector molds. Since the through hole 13 is provided on the side facing away from the plug-in cavity 12 and located in the opening and closing direction of the front and rear molds, the front and rear molds only need to be plugged in to form the mold. When demolding, the front and rear molds can be opened directly without providing a running slider structure, thereby reducing the mold development cost and improving production efficiency. At the same time, since the through hole 13 is provided on the side of the board end body 11, it can also reduce the entry of foreign matter into the plug-in cavity 12, thereby ensuring the plug-in and contact performance of the connector.

[0032] like Figure 2 , Figures 4 to 6 As shown, in some embodiments of the wire-to-board connector described in this embodiment, the number of the through holes 13 is two, the number of the first clamping platforms 14 is two, and the number of the second clamping platforms 23 is two. Through the above arrangement, the wire end connector and the board end connector are more secure when plugged in, and are not easy to loosen, and the structure has higher reliability in use.

[0033] like Figure 4 and Figure 5 As shown, in some embodiments of the wire-to-board connector described in this embodiment, a guide groove 15 is provided in the plug-in cavity 12, and a guide platform 24 is provided in the wire end body 21. When the board end connector and the wire end connector are plugged in, the guide platform 24 is inserted into the guide groove 15. In this embodiment, the guide groove 15 and the guide platform 24 are provided to cooperate, so as to guide and limit the wire end connector when it is inserted into the plug-in cavity 12, thereby ensuring reliable electrical plug-in between the board end connector and the wire end connector.

[0034] like Figure 4 and Figure 5 As shown, in some embodiments of the wire-to-board connector described in this embodiment, guide grooves 15 are provided on both sides of the plug-in cavity 12, and guide platforms 24 are provided on both sides of the pressing tongue plate 22 of the wire end body 21. Through the above arrangement, the wire end connector is not easily offset during the plug-in process, and the wire end connector and the board end connector are accurately plugged in.

[0035] As shown in the wire-to-board connector of this embodiment, in some embodiments, fixing pieces 16 are embedded on both sides of the board end body 11. In this embodiment, the fixing pieces 16 are provided to position the board end connector.

[0036] like Figure 1 and Figure 4As shown, in some embodiments of the wire-to-board connector described in this embodiment, the fixing plate 16 has a first pin 161 and a second pin 162, and the plugging direction of the first pin 161 is perpendicular to the plugging direction of the second pin 162. In this embodiment, by setting the first pin 161 and the second pin 162 with plugging directions perpendicular to each other, the connector can be applied to a horizontal installation or a vertical installation environment, such as Figure 2 and Figure 6 As shown, the structure is more flexible.

[0037] like Figure 4 and Figure 5 As shown, in the wire-to-board connector described in this embodiment, in some embodiments, the pressing tongue plate 22 has a notch 221, and the wire end body 21 is provided with a boss 25 at the position of the notch 221. In this embodiment, the notch 221 is provided so that the pressing tongue plate 22 has greater elasticity, and the boss 25 is provided so that during the plugging process, the boss 25 is used to abut against the inner top wall of the plugging cavity 12, thereby enhancing the anti-dropping ability of the wire end connector, thereby ensuring the structural stability of the wire end body 21, and having higher reliability.

[0038] like Figure 5 As shown, in some embodiments of the wire-to-board connector described in this embodiment, the opening of the plug-in cavity 12 is provided with a guide opening 121 at a position corresponding to the first card platform 14. In this embodiment, the guide opening 121 is provided so that the second card platform 23 can enter the plug-in cavity 12 under the guidance of the guide opening 121, and the plug-in operation is smoother.

[0039] like Figures 2 to 6 As shown, in some embodiments of the wire-to-board connector described in this embodiment, the board-end connector further includes board-end terminals 17 arranged side by side in the insertion cavity; the wire-end connector further includes wire-end terminals 26 arranged side by side on the wire-end body 21. In this embodiment, the board-end terminals 17 and the wire-end terminals 26 are arranged so that when plugged in, the electrical contact between the board-end terminals 17 and the wire-end terminals 26 is utilized to achieve electrical conduction between the wire end and the board end. Figure 2 and Figure 6 As shown, this embodiment can adapt to the use environment of horizontal installation or vertical installation by setting the pin direction of the board terminal 17.

[0040] The above is only a preferred embodiment of the present utility model, so any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the protection scope of the present utility model patent application.
