Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a horizontal plug-in board connector. Background Art

[0002] In the prior art, a horizontal plug-in connector is generally a connector mounted on a printed circuit board and needs to be welded together with circuit pins.

[0003] Existing connectors generally have different PIN pin models. For example, taking a connector with two rows of PIN pins, a connector with fewer PIN pins is shorter, while a connector with more PIN pins is longer. When the male connector of the short connector is inserted into the female connector of the long length, the anti-mismatch structure on the prior art connector is prone to failure, resulting in the terminals touching when the male and female terminals are inserted, which may cause a short circuit and burn the equipment.

[0030] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, a horizontal plug-in board connector comprises a male connector 1 and a female connector 2 , wherein the male connector 1 can be inserted into a corresponding slot 21 of the female connector 2 .

[0032] like Figure 2 and Figure 3 As shown, the upper surface 1a of the male connector 1 has a first limiting portion 11 extending upward, and the first limiting portion 11 is close to the first docking surface 12 of the male connector 1. The lower surface 1b of the male connector 1 has a second limiting portion 13 and a third limiting portion 14 extending downward, and the third limiting portion 14 is respectively arranged on the left and right sides of the second limiting portion 13, the width W1 of the second limiting portion 13 is greater than the width W2 of the third limiting portion 14, and the height H1 of the second limiting portion 13 is greater than the height H2 of the third limiting portion 14.

[0033] like Figure 4 and Figure 5As shown, the top wall 2a of the socket 21 of the female seat 2 is provided with a first limiting groove 22 corresponding to the first limiting portion 11, the bottom wall 2b of the socket 21 of the female seat 2 is provided with a second limiting groove 23 corresponding to the second limiting portion 13, and the bottom wall 2b of the socket 21 of the female seat 2 is provided with a third limiting groove 24 corresponding to the third limiting portion 14.

[0034] The present application effectively strengthens the foolproof structure by extending the first limiting portion 11 on the upper surface 1a of the male connector 1. This arrangement ensures that only connectors in the correct direction can be inserted into the female connector 2, greatly reducing the risk of short circuit caused by reverse insertion; in addition, the introduction of the multi-level arrangement of the second limiting portion 13 and the third limiting portion 14 allows the terminal contact and short circuit problems to be effectively prevented through the matching of the limiting grooves even if the short-length male connector 1 is inserted into the long-length female connector 2. This improves the applicability of the connector in different lengths; and by providing the corresponding first, second, and third limiting grooves 24 on the top wall 2a and bottom wall 2b of the matching slot 21 of the female connector 2, the correct alignment of the male connector 1 and the female connector 2 is further ensured, increasing the stability and safety of the connector.

[0035] Therefore, the horizontal plug-in connector of the present application effectively solves the problem of easy failure of the anti-fool structure in the prior art through an improved structural setting, improves the safety, stability and reliability of the connector, reduces the risks associated with short circuits, and provides better protection for the reliable operation of the equipment.

[0036] In the present application, the width of the second limiting portion 13 is greater than the width of the third limiting portion 14, and the height of the second limiting portion 13 is greater than the height of the third limiting portion 14, which has the following effects:

[0037] (1) The second limiting portion 13 has a large width and height, which ensures that the plug can only be inserted into the slot in the correct direction. This helps prevent reverse insertion, that is, ensures that the plug can only be correctly inserted into the matching female socket 2 to avoid connection errors.

[0038] (2) The second limiting portion 13 is relatively large, providing a more obvious limiting effect for the plug, making it easier to determine the correct direction when inserting. This improves the directionality of the connector and reduces the possibility of misoperation.

[0039] (3) Since the second limiting portion 13 is larger in width and height than the third limiting portion 14, the plug is more strongly limited when inserted, which helps ensure that the plug is inserted into the designated position and reduces possible deviation or shaking of the plug.

[0040] (4) The plug is significantly limited when inserted, which helps ensure that each pin or terminal of the connector is correctly aligned. This improves the reliability of the connection and prevents loose connections caused by inaccurate plug positioning.

[0041] In general, the arrangement in which the width and height of the second limiting portion 13 are greater than those of the third limiting portion 14 strengthens the directionality and limiting effect of the plug, and helps to ensure that the connector can be connected accurately and reliably when inserted.

[0042] like Figure 4 As shown, in this embodiment, the upper surface of the female socket 2 extends upward with a first thickened portion 25, and the lower surface of the female socket 2 extends downward with a second thickened portion 26. The first thickened portion 25 and the second thickened portion 26 provide additional material on the upper and lower surfaces of the connector, enhancing the overall structural strength of the connector and making it more durable. This is beneficial for long-term use and frequent plugging and unplugging of the connector.

[0043] like Figure 2 and Figure 4 As shown, in this embodiment, the upper surface 1a of the male connector 1 is provided with a first locking portion 15, and the female connector 2 is provided with a second locking portion 27 corresponding to the first locking portion 15. The design of the locking portion may provide additional locking force, making the connector more secure during the plugging and unplugging process. This helps to reduce the shaking and loosening of the connector and improve the stability of the connection.

[0044] like Figure 2 As shown, in this embodiment, locking guides 16 are respectively provided on both sides of the first locking portion 15. The locking guides 16 are provided on both sides of the first locking portion 15 to help guide the connector to be correctly inserted. Such a setting provides a more intuitive insertion direction guide, reduces the possibility of misoperation, and ensures that the connector is correctly inserted into the female socket 2.

[0045] like Figure 2 As shown, in this embodiment, a position-limiting portion 17 is provided on the rear side of the male connector 1. The presence of the position-limiting portion 17 can ensure that the male connector 1 is correctly inserted into the female connector 2 and reaches a predetermined insertion depth. This helps to maintain the correct position of the connector element and reduces connection problems caused by insufficient or excessive insertion.

[0046] like Figure 2 As shown, in this embodiment, the upper surface 1a and the lower surface 1b of the male connector 1 are respectively provided with multiple terminal pressing pieces 18. The multiple terminal pressing pieces 18 can provide more uniform terminal pressure to ensure the stability of the connection. This helps to reduce the risk of loosening and failure of the connector during use.

[0047] like Figure 3As shown, in this embodiment, a plug-in limiting protrusion 28 is provided in the plug-in slot 21 of the female socket 2, and the female terminal 3 of the female socket 2 is inserted on the plug-in limiting protrusion 28. Through the plug-in limiting protrusion 28, the connector plug will be limited by the protrusion when inserted into the female socket 2, so that the plug can only be inserted to a specific depth. This limiting effect helps to ensure that the various terminals of the connector are correctly aligned, prevent the plug from being inserted insufficiently or too deeply, and reduce connection problems caused by incorrect insertion.

[0048] like Figure 6 As shown, in this embodiment, a first limiting plate 29 is provided on the front side of the female base 2, and the first limiting plate 29 is provided with a plurality of first terminal limiting grooves 291 corresponding to the lower row of female terminals of the female base 2. The presence of the first terminal limiting grooves 291 can prevent the female terminals from being misplaced during insertion, ensuring that each terminal is inserted into the correct position. This is crucial to maintaining the electrical and mechanical properties of the connector.

[0049] like Figure 6 As shown, in this embodiment, the front side of the female base 2 is provided with a second terminal limit support plate 2c corresponding to the upper row of female terminals of the female base 2. The second terminal limit support plate 2c provides additional support to ensure that the bent portion of the upper row of female terminals is stably positioned inside the connector. This helps to reduce the shaking and vibration of the terminals during the plugging and unplugging process and improves the mechanical stability of the connector.

[0050] like Figure 4 As shown, in this embodiment, a pin 2d is provided at the bottom of the female socket 2. The presence of the pin 2d can make the female socket 2 more firmly mounted on the printed circuit board (PCB). The pin 2d is connected to the PCB by welding or other fixing methods to ensure that the female socket 2 is not easy to loosen or shift during use.
