This makes connectors an indispensable part of modern electronic equipment.

[0003] Traditional pluggable connectors consist of male and female plugs, which are directly plugged into each other to form a circuit connection. However, the male and female plugs may be in a partial plugging state when plugged in, meaning that although they are connected, the connection is unreliable. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a plug-in connector.

[0005] The technical solution adopted by this utility model is as follows: This application provides a pluggable connector, including a male plug and a female plug. The male plug includes a plug block portion, and the female plug includes a socket portion. A plug sleeve is provided on the plug block portion. A stop mechanism is provided between the plug block portion and the plug sleeve. The stop mechanism enables the plug sleeve to have a pre-installed position and a connected position when it is fitted onto the plug block portion. When the plug sleeve is in the pre-installed position, the male plug and the female plug cannot be connected. When the plug sleeve is in the connected position, the male plug and the female plug are connected when they are plugged in. When the plug block portion and the socket portion are plugged in, the plug sleeve can be pushed from the pre-installed position to the connected position.

[0006] In some embodiments, the gear shifting mechanism includes two gear shifting slots and a gear shifting protrusion, one of which is disposed on the insert block portion and the other on the insert sleeve.

[0007] In some embodiments, the gear slot and gear protrusion are provided with movable guide surfaces on their front and rear sides.

[0008] In some embodiments, the male plug is provided with an installation channel, a terminal block is provided at the front end of the installation channel, an abutment is provided on the terminal block, and an elastic arm is provided on the male plug facing the front end of the installation channel. The elastic arm and the abutment abut against each other to fix the terminal block in the installation channel.

[0009] In some embodiments, the front end of the elastic arm is provided with a positioning protrusion facing the terminal block, and when the sleeve is inserted into the protrusion, the positioning protrusion is pressed against the terminal block.

[0010] In some embodiments, the elastic arm is provided with a first inclined surface located on the end face of the elastic arm facing away from the terminal block, which gradually slopes toward the terminal block towards the front end of the mounting channel, and the inner wall of the socket is provided with a second inclined surface with the same slope as the first inclined surface.

[0011] In some embodiments, the rear end of the positioning protrusion is provided as a smooth guide surface, and the front end of the positioning protrusion is provided with a third inclined surface. The third inclined surface is inclined toward the front end of the mounting channel on the side near the wiring terminal, and the third inclined surface abuts against the abutting part.

[0012] In some embodiments, a sealing sleeve is provided on the insert portion, the sealing sleeve being located behind the insert. When the insert is in the connected position, the insert and the sealing sleeve abut against each other, and the sealing sleeve presses against the insert portion and the insertion port portion.

[0013] In some embodiments, the terminal block has a plug-in interface at its front end and a wiring port at its rear end, and the female plug-in has pins that are plugged into and cooperate with the plug-in interface.

[0014] In some embodiments, a first foolproof structure is provided between the sleeve and the plug portion, and / or a second foolproof structure is provided between the sleeve and the socket portion.

[0015] The beneficial effects of this utility model are as follows: When the plug-in connector of this utility model is manufactured, the plug-in assembly is located in the pre-installed position. When the user uses it, due to the setting of the locking mechanism, there are only two states: connected and disconnected. Only when the plug-in is pushed to the connection position can the male plug and female plug be plugged in and connected.

[0029] The following description provides specific application scenarios and requirements for this specification, intended to enable those skilled in the art to make and use the contents of this specification. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "longitudinal", "lateral", "radial", "length", "width", "thickness", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element or component to have a specific orientation, or to be constructed and operated in a specific orientation.

[0031] Secondly, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different components and should not be construed as limiting the embodiments of this application.

[0032] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two devices, components, or parts.

[0033] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.

[0035] like Figures 1 to 12 As shown in the figure, this specification provides a pluggable connector, including a male plug 1 and a female plug 2. The male plug 1 includes a plug block portion 3, and the female plug 2 includes a socket portion 4. A socket sleeve 5 is provided on the plug block portion 3. A stop mechanism 6 is provided between the plug block portion 3 and the socket sleeve 5. The stop mechanism 6 allows the socket sleeve 5 to have a pre-installed position and a connected position when it is fitted onto the plug block portion 3. When the socket sleeve 5 is in the pre-installed position, the male plug 1 and the female plug 2 cannot be connected. When the socket sleeve 5 is in the connected position, the male plug 1 and the female plug 2 are connected. When plug-in 1 and female plug-in 2 are plugged into the connection position, the socket 5 can be pushed from the pre-installed position to the connected position when the plug block 3 and the socket 4 are plugged in. With this setting, the socket 5 is installed in the pre-installed position when the plug-in connector is shipped from the factory. When the user uses it, due to the setting of the stop mechanism 6, there are only connected and disconnected states. Only when the socket 5 is pushed to the connected position can the male plug-in 1 and female plug-in 2 be plugged into the connection position. Otherwise, it is in the disconnected state, which greatly improves the safety and reliability of the connector.

[0036] Specifically, the gear shift mechanism 6 includes two gear shift grooves 600 and one gear shift protrusion 601, one of which is disposed on the insert block 3 and the other is disposed on the insert sleeve 5. The gear shift grooves 600 and the gear shift protrusion 601 are provided with moving guide surfaces 602 on their front and rear sides. The front and rear sides are understood as the two sides in the insertion direction of the male insert 1 and the female insert 2. The moving guide surfaces 602 help the gear shift protrusion 601 to move and switch between the two gear shift grooves 600. It can be an inclined surface, an arc surface, or a combination of an inclined surface and an arc surface.

[0037] like Figure 3 and Figure 4 As shown, two positioning grooves 600 are provided at the bottom of both sides of the insert portion 3, and the positioning grooves 600 are trapezoidal grooves. Positioning protrusions 601 are provided on both sides of the inner bottom wall of the insert sleeve 5. The positioning protrusions 601 are trapezoidal protrusions. Since the connector is generally made of plastic, which has a certain degree of elasticity, two positioning grooves 600 and one positioning protrusion 601 can achieve a two-position function. It should be understood that in addition to trapezoids, shapes such as triangles and semicircles can also achieve the positioning function.

[0038] like Figure 12 As shown, the two side walls of the insert part 3 are provided with two stop grooves 600, and the two inner side walls of the corresponding insert sleeve 5 are provided with stop protrusions 601 to cooperate with them.

[0039] It should be understood that the gear slot 600 and gear protrusion 601 can also be configured in other forms, which will not be listed here.

[0040] In some embodiments, the male plug-in 1 is provided with an installation channel 100, a terminal block 7 is provided at the front end of the installation channel 100, an abutment portion 700 is provided on the terminal block 7, an elastic arm 101 is provided on the male plug-in 1 facing the front end of the installation channel 100, a limit block is provided at the front end of the installation channel 100, and a positioning protrusion portion 102 is provided at the front end of the elastic arm 101 facing the terminal block 7. It can be understood that the front end is the end close to the female plug-in 2. During assembly, the terminal block 7 is simply inserted from the rear end of the installation channel 100, and the terminal block 7 will push up the elastic arm 101. When it is inserted into place, that is, when the front end of the terminal block 7 abuts against the limit block, the elastic arm 101 falls down, causing the positioning protrusion portion 102 and the abutment portion 700 to abut against each other, thus fixing the terminal block 7 in the installation channel 100. This simplifies the assembly process of the terminal block 7 and eliminates the need for additional fasteners.

[0041] When the insert 5 is inserted into the insert block 3, the positioning protrusion 102 is pressed against the terminal 7, thus the terminal 7 is firmly fixed in the mounting channel 100, which greatly improves the stability and reliability of the connector connection.

[0042] Among them, such as Figure 7 As shown, the elastic arm 101 is provided with a first inclined surface 103, which is located on the end face of the elastic arm 101 facing away from the terminal 7. It gradually slopes towards the front end of the mounting channel 100 and towards the terminal 7. The inner wall of the plug sleeve 5 is provided with a second inclined surface 500 with the same slope as the first inclined surface 103. In this way, when the plug sleeve 5 is inserted into the plug block 3, it is smoother. Under the guidance of the cooperation of the first inclined surface 103 and the second inclined surface 500, the elastic arm 101 quickly presses down to fix the terminal 7.

[0043] Furthermore, the rear end of the positioning protrusion 102 is configured as a smooth guide surface 104, which makes it easier for the terminal block 7 to lift the elastic arm 101 when inserted into the installation channel 100.

[0044] Furthermore, such as Figure 7 As shown, the front end of the positioning protrusion 102 is provided with a third inclined surface 105. The third inclined surface 105 is inclined towards the front end of the mounting channel 100 on the side near the terminal 7. The third inclined surface 105 abuts against the abutting part 700. A cavity is formed below the abutting part 700, or the abutting part 700 is an abutting inclined surface with the same slope as the third inclined surface 105. With this configuration, under the pressure of the sleeve 5, the lower side of the third inclined surface 105 extends into the cavity 703 below the abutting part 700, which is more secure and reliable than the abutting of two planes.

[0045] In some embodiments, a sealing sleeve 8 is fitted onto the plug portion 3. The sealing sleeve 8 is made of materials such as silicone or rubber. The sealing sleeve 8 is located behind the plug sleeve 5. When the plug sleeve 5 is in the connected position, the plug sleeve 5 and the sealing sleeve 8 abut against each other, and the sealing sleeve 8 presses between the plug portion 3 and the plug portion 4. This arrangement enables the connector to have waterproof and dustproof functions. Furthermore, when the plug-in connector leaves the factory, the plug sleeve 5 is assembled in the pre-installed position, which can prevent the sealing sleeve from being lost during circulation.

[0046] Furthermore, the outer wall of the sealing sleeve 8 is provided with at least two or more annular protrusions to form a better seal between the insert block portion 3 and the insertion port portion 4.

[0047] In some embodiments, such as Figures 7 to 9 As shown, the terminal block 7 has a plug interface 701 at its front end and a wiring port 702 at its rear end. The female plug 2 has a pin 200 that is plugged into and cooperates with the plug interface 701.

[0048] In some embodiments, a first anti-misfit structure 9 is provided between the sleeve 5 and the insert block 3, and / or a second anti-misfit structure 10 is provided between the sleeve 5 and the insert portion 4, to prevent misassembly between corresponding parts, such as... Figure 10As shown, the first foolproof structure 9 includes a vertical plate 900 disposed at the front end of the sleeve 5 and a vertical groove 901 disposed at the front end of the insert block 3. In this way, the sleeve 5 can only be inserted into the insert block 3 from its rear end, and the vertical plate 900 can be inserted into the vertical groove 901. Otherwise, the sleeve 5 cannot be properly inserted, thus avoiding the front and rear ends of the sleeve 5 being reversed when it is inserted. At the same time, since the vertical plate 900 is asymmetrically disposed relative to the sleeve 5 and the vertical groove 901 is asymmetrically disposed relative to the insert block 3, it also avoids the left and right ends of the sleeve 5 being reversed when it is inserted.

[0049] like Figure 11 As shown, the outer wall of the socket 5 is provided with a guide groove 1000 along its insertion direction, and the inner wall of the socket 4 is provided with a guide protrusion 1001 corresponding to the guide groove 1000. For example, the upper outer wall of the socket 5 is provided with two guide grooves 1000, and the lower outer wall is provided with one guide groove 1000. The guide protrusion 1001 is provided accordingly. This can prevent the upper and lower ends and the left and right ends from being reversed when the socket 5 is inserted.
