[0030] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] In the description of the embodiments of the present application, it should be noted that the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the embodiments of the present application and to simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the embodiments of the present application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0033] Connectors, also known as electrical connectors, are typically divided into female and male ends, or sockets and plugs. Both the socket and plug of a PCB connector typically come with a wiring harness. One of the wiring harnesses connects to the PCB, while the other connects to a power source, signal source, or signal receiver. This connection between the socket and plug transmits current or signals from one end of the connector to the other.

[0034] In the related art, the terminal connectors on the PCB used to connect the wiring harness are usually not waterproof or dustproof. The waterproof method is usually to connect the connector socket to the PCB through the wiring harness, and then seal the socket to the PCB. The protection between the PCB and the connector is achieved through the protective performance between the connector socket and the plug. However, the wiring harness between the socket and the PCB usually occupies a large space, has low versatility, and has low PCB utilization efficiency.

[0035] Based on the above situation, the first aspect of the embodiment of the present application provides a surface mounted connector 10. Figures 1 to 7 The connector 10 includes a socket 11 and a plug 12. The socket 11 includes a socket housing 111, a socket circuit board 112, and a first connector 113 located inside the socket housing 111. The socket housing 111 is sealed and connected to one side of the socket circuit board 112. The first connector 113 is electrically connected to the socket circuit board 112 and is located inside the socket housing 111. The first connector 113 is provided with a plug channel 113a extending along the height direction of the socket 11. The plug 12 includes a plug housing 121 and a second connector 122. The second connector 122 is at least partially disposed inside the plug housing 121. The socket housing 111 is sealed and matched with the plug housing 121. The second connector 122 can be inserted into the plug channel 113a and is electrically connected to the first connector 113.

[0036] It should be noted that SMT (Surface Mount Technology), also known as surface mounting technology or surface mount technology, is a circuit assembly technology that mounts pinless or short-lead surface mount components (SMC / SMD, SMC-Surface Mount Components / SMD-Surface Mount Device) on the surface of a printed circuit board (PCB) or other substrate, and solders and installs them by reflow soldering or dip soldering.

[0037] The socket 11 of the connector 10 in the embodiment of the present application is a surface mounted component mounted on the surface of a PCB via SMT.

[0038] Exemplarily, the socket 11 is directly connected to the socket circuit board 112 by soldering.

[0039] It should be noted that the socket circuit board 112 can be the target product itself to which the connector 10 is to be connected; the socket circuit board 112 can also be a transition piece, and the connector 10 is indirectly connected to the target product to which the connector 10 is to be connected through the socket circuit board 112.

[0040] Exemplarily, the socket circuit board 112 is a circuit board on which a light emitting diode (LED) is mounted. The socket 11 is mounted on the socket circuit board 112 as a surface mounted component. The power supply of the plug 12 is directly connected to the LED circuit board through the socket 11, thereby energizing the LED.

[0041] Exemplarily, the socket housing 111 is a plastic part.

[0042] Exemplarily, the plug housing 121 is a plastic part.

[0043] It should be noted that the socket housing 111 and the plug housing 121 can be square, circular or other shapes, which are not limited here.

[0044] The number of the first connecting members 113 may be one or more, and the number of the second connecting members 122 may also be one or more. The number of the first connecting members 113 and the number of the second connecting members 122 may be the same or different.

[0045] The multiple mentioned in the embodiments of the present application refers to a number of two or more.

[0046] For example, the first connector 113 is a socket, and the second connector 122 is a pin. The socket and the pin can be plugged together.

[0047] Among them, the form of plugging and matching multiple sockets with multiple pins can be called a multi-pin connection method.

[0048] The socket shell 111 is sealed and connected to one side of the socket circuit board 112, which means that the socket shell 111 is installed on one of the large surfaces of the socket circuit board 112, and a sealed connection is formed between the socket shell 111 and the socket circuit board 112, thereby improving the overall protection effect of the connector 10 and improving the situation where foreign matter such as water or dust enters the connector 10 through the gap between the socket shell 111 and the socket circuit board 112, causing the first connecting member 113 to easily fail in electrical connection.

[0049] Among them, electrical connection failure includes short circuit, open circuit and other forms.

[0050] Exemplarily, the socket housing 111 and the socket circuit board 112 are sealed and connected by glue.

[0051] The first connector 113 is electrically connected to the socket circuit board 112 and is located inside the socket housing 111. That is to say, the first connector 113 of the socket 11 for electrical connection is directly connected to the socket circuit board 112, and the socket housing 111 is also directly connected to the socket circuit board 112. The socket circuit board 112 can be the target product itself to be connected by the connector 10, thereby eliminating the connecting wire between the socket housing 111 and the socket circuit board 112, so that the overall socket 11 installed on the socket circuit board 112 is reduced in size and has a more compact structure, thereby improving the versatility of the connector 10.

[0052] It should be noted that the electrical connection may include electrical connection and mechanical connection.

[0053] The first connector 113 is provided with a plug-in channel 113a extending along the height direction of the socket 11. The second connector 122 can be inserted into the plug-in channel 113a along the height direction and electrically connected to the first connector 113. In this way, the plug-in channel 113a can guide and fix the second connector 122, which is beneficial for the removal and insertion of the second connector 122 into the plug-in channel 113a. At the same time, it can also strengthen the connection strength between the first connector 113 and the second connector 122, thereby improving the reliability and safety of the electrical connection.

[0054] The second connector 122 is at least partially disposed in the plug housing 121 . Part of the second connector 122 may be disposed in the plug housing 121 , and part may be exposed from the plug housing 121 . Alternatively, the second connector 122 may be completely disposed in the plug housing 121 .

[0055] The second connecting member 122 is fixedly connected to the plug housing 121 .

[0056] Specifically, the receptacle 11 also includes a sealing member 116. A sealing groove 111d is formed in the receptacle housing 111, facing away from the receptacle circuit board 112. The sealing member 116 is disposed within the sealing groove 111d. The plug housing 121 protrudes vertically toward the receptacle 11, forming a flange 121c that mates with the sealing groove 111d. When the second connector 122 is vertically inserted into the insertion passage 113a, the flange 121c extends into the sealing groove 111d and abuts against the sealing member 116, thereby achieving a sealed fit between the receptacle housing 111 and the plug housing 121.

[0057] In some embodiments, the protection level between the socket shell 111 and the plug shell 121 of the connector 10, and between the socket shell 111 and the socket circuit board 112 of the connector 10 can reach IP67, that is, it can completely prevent the intrusion of foreign objects and dust, and at the same time has protection performance against the impact of immersion in water up to 1 meter deep for 30 minutes.

[0058] In some embodiments, the plug 12 further includes a wiring harness 125 , and the second connector 122 is electrically connected to the wiring harness 125 , thereby enabling transmission of signals or current.

[0059] Exemplarily, the wiring harness 125 is a lead wire of the plug 12 , and is used to connect the plug 12 to a power terminal or a signal terminal.

[0060] For example, the number of the wiring harnesses 125 may be one, two, three, four, five, six, seven or eight, etc., which is not limited here.

[0061] The surface-mount connector 10 of the present embodiment improves the protective effect between the socket housing 111 and the socket circuit board 112 by sealingly connecting the socket housing 111 to one side of the socket circuit board 112. Furthermore, the first connector 113 is provided with an insertion channel 113a extending along the height direction of the socket 11. The second connector 122 can be inserted into the insertion channel 113a along the height direction and electrically connected to the first connector 113. Thus, the insertion channel 113a can guide and secure the second connector 122, thereby increasing the connection strength between the first connector 113 and the second connector 122, thereby improving the reliability and safety of the electrical connection. Furthermore, by directly connecting the first connector 113 and the socket housing 111 to the socket circuit board 112, the connecting wires between the socket housing 111 and the socket circuit board 112 are eliminated, resulting in a smaller and more compact socket 11 mounted on the socket circuit board 112, thereby improving the versatility of the connector 10.

[0062] For some examples, see Figures 3 to 7 The socket 11 includes a first reinforcement member 114. The first reinforcement member 114 is formed with a guide groove 114a extending in the height direction. The first connector 113 is inserted into the guide groove 114a.

[0063] The first connecting member 113 is inserted into the guide groove 114a formed by the first reinforcement member 114, so that the first reinforcement member 114 can strengthen and fix the first connecting member 113, thereby improving the situation where the first connecting member 113 is easily damaged or deformed during the plugging process of the first connecting member 113 and the second connecting member 122, thereby improving the connection reliability between the first connecting member 113 and the second connecting member 122.

[0064] Exemplarily, the first reinforcement member 114 is a plastic member.

[0065] It should be noted that the first reinforcement member 114 and the first connection member 113 can be connected in a snap-fit, interference fit, adhesive connection or other forms.

[0066] It should be noted that the first reinforcement member 114 can be a split design or an integrally formed structure.

[0067] Exemplarily, the first reinforcement member 114 is formed with a guide groove 114 a, so that one first connector 113 is provided with one first reinforcement member 114 , and each first reinforcement member 114 is independent of each other, so that each first connector 113 does not contact each other.

[0068] For example, the first reinforcement member 114 is in a block shape. There is one first reinforcement member 114 , and a plurality of guide grooves 114 a are formed on the first reinforcement member 114 . The first connecting member 113 is inserted into the guide grooves 114 a , thereby achieving reinforced fixation of the first connecting member 113 .

[0069] Therefore, by inserting the first connecting member 113 into the guide groove 114a formed by the first reinforcement member 114, the first reinforcement member 114 can strengthen and fix the first connecting member 113, thereby improving the situation where the first connecting member 113 is easily damaged or deformed during the plugging process of the first connecting member 113 and the second connecting member 122, thereby improving the connection reliability between the first connecting member 113 and the second connecting member 122.

[0070] For some examples, see Figures 3 to 7 The plug 12 includes a plug circuit board 123 and a second reinforcement member 124. The plug circuit board 123 and the second reinforcement member 124 are disposed within the plug housing 121. The second reinforcement member 124 is formed with a retaining groove 124a extending in the height direction. At least a portion of the second connector 122 is inserted into the retaining groove 124a. One end of the second connector 122 is connected to the plug circuit board 123 in the height direction, while the other end is inserted into the insertion channel 113a and electrically connected to the first connector 113.

[0071] It should be noted that in the connector 10 provided in the embodiment of the present application, the first reinforcement member 114 and the second reinforcement member 124 can be used separately on the socket 11 or the plug 12, or can be used on both the socket 11 and the plug 12 at the same time.

[0072] It can be understood that by inserting at least a portion of the second connecting member 122 into the limiting groove 124a, the second reinforcement member 124 can also strengthen and fix the second connecting member 122, thereby improving the situation where the second connecting member 122 is easily damaged or deformed during the plug-in process of the first connecting member 113 and the second connecting member 122, thereby improving the connection reliability between the first connecting member 113 and the second connecting member 122.

[0073] At least a portion of the second connecting member 122 is inserted into the limiting groove 124 a , so that another portion of the second connecting member 122 is exposed, inserted into the insertion channel 113 a , and electrically connected to the first connecting member 113 .

[0074] Exemplarily, the second reinforcement member 124 is a plastic member.

[0075] It should be noted that the second reinforcement member 124 and the second connection member 122 can be connected in a snap-fit, interference fit, adhesive connection or other forms.

[0076] It should be noted that the second reinforcement member 124 may be a split design or an integrally formed structure.

[0077] It should be noted that the connection between the plug circuit board 123 and the second reinforcement member 124 and the plug housing 121 can be a detachable connection or a non-detachable connection.

[0078] Specifically, after the second connecting member 122 is welded to the plug circuit board 123, the second connecting member 122 is inserted into the limiting groove 124a of the second reinforcement member 124, and the plug shell 121 is formed by directly injection molding outside the assembly of the plug circuit board 123, the second connecting member 122 and the second reinforcement member 124, so that the plug circuit board 123 and the second reinforcement member 124 are embedded in the plug shell 121 and form a non-detachable connection with the plug shell 121.

[0079] Therefore, by inserting at least a portion of the second connecting member 122 into the limiting groove 124a of the second reinforcement member 124, the second connecting member 122 can be strengthened and fixed by the second reinforcement member 124, thereby improving the situation where the first connecting member 113 is easily damaged or deformed during the plugging process of the first connecting member 113 and the second connecting member 122, thereby improving the connection reliability between the first connecting member 113 and the second connecting member 122.

[0080] In some embodiments, the depth of the guide groove 114 a is greater than the height of the insertion channel 113 a .

[0081] It should be noted that the first connecting member 113 is disposed at the bottom end of the guide groove 114 a , so that the first connecting member 113 can be connected to the socket circuit board 112 .

[0082] By setting the depth of the guide groove 114a to be higher than the dimension of the plug-in channel 113a along the height direction, the insertion space at the top of the plug-in channel 113a is made larger, which is conducive to guiding the second connecting member 122, thereby making the connection process between the second connecting member 122 and the first connecting member 113 smoother and making the second connecting member 122 less likely to be damaged.

[0083] For some examples, see Figure 3 and Figure 6 The first connector 113 includes a main body 1131 and a connecting portion 1132. The connecting portion 1132 is connected to the bottom of the main body 1131. The main body 1131 has an inserting channel 113a inside. The connecting portion 1132 is connected to the socket circuit board 112.

[0084] It should be noted that there is at least a plug-in channel 113a at the top of the main body 1131, and the plug-in channel 113a is connected to the top end face of the main body 1131. The second connecting member 122 is inserted into the plug-in channel 113a from the top of the main body 1131, thereby realizing the cooperation between the first connecting member 113 and the second connecting member 122.

[0085] Exemplarily, the first connecting member 113 is columnar.

[0086] The connecting portion 1132 is connected to the bottom of the main body 1131 , which facilitates direct connection between the first connecting member 113 and the socket circuit board 112 .

[0087] For some examples, see Figure 3 and Figure 6 The main body 1131 is disposed in the guide groove 114 a. When projected on a plane perpendicular to the extending direction of the insertion channel 113 a, at least a portion of the projection of the connecting portion 1132 is exposed outside the projection of the first reinforcement member 114 .

[0088] It should be noted that the main body 1131 is disposed in the guide groove 114 a , thereby achieving fixation of the main body 1131 by the first reinforcement member 114 .

[0089] It is understandable that there are usually multiple first connecting members 113, and each first connecting member 113 is independent of each other. By opening multiple guide grooves 114a through a first reinforcement member 114, each first connecting member 113 is combined into a component, which is more conducive to assembly and improves assembly efficiency.

[0090] Exemplarily, the extension direction of the plug-in channel 113a is the vertical direction, and the projection on the plane perpendicular to the extension direction of the plug-in channel 113a is the projection on the horizontal plane. At least part of the projection of the connecting portion 1132 is exposed to the projection of the first reinforcement 114, that is, the connecting portion 1132 is exposed to the outer wall of the first reinforcement 114, so that the assembly of the first connecting portion 113 and the first reinforcement 114 can be directly welded to the socket circuit board 112 through the exposed connecting portion 1132, thereby improving the convenience and efficiency of assembly.

[0091] Illustratively, the bottom of the first reinforcement 114 has an avoidance groove for avoiding the connection portion 1132 , so that the connection portion 1132 is exposed from the avoidance groove to the projection of the first reinforcement 114 , thereby improving the compactness of the assembly of the first connection member 113 and the first reinforcement 114 .

[0092] For some examples, see Figures 1 to 5 The socket housing 111 is provided with a first clamping portion 111a, and the plug housing 121 is provided with a second clamping portion 121a. At least part of the fastening surface of the first clamping portion 111a is a first curved surface, and at least part of the fastening surface of the second clamping portion 121a is a second curved surface. The first clamping portion 111a and the second clamping portion 121a are clamped together through the first curved surface and the second curved surface.

[0093] It is understandable that the snap-fitting between the first curved surface and the second curved surface may be a line-to-line contact fit, a surface-to-surface contact fit, or other forms.

[0094] Therefore, the first clamping portion 111a and the second clamping portion 121a are engaged with each other through the first curved surface and the second curved surface, so that the contact area of ​​the engagement is reduced or the engagement amount is reduced, and the plug shell 121 is easier to separate from the socket shell 111, which is conducive to pulling the plug 12 out of the socket 11.

[0095] For some examples, see Figures 1 to 5 Socket 11 includes a fixing member 115. A slot 111b extending in the height direction is provided on the peripheral outer wall of socket housing 111. Socket housing 111 is fitted over socket circuit board 112. Fixing member 115 is positioned within slot 111b and connected to circuit board 112 to limit the position of socket housing 111.

[0096] The peripheral outer wall of the socket housing 111 is provided with a card slot 111 b extending in the height direction, that is, the card slot 111 b can be provided on any side of the peripheral outer wall.

[0097] Among them, the card slots 111b can be set at both ends along the length direction of the socket shell 111, the card slots 111b can be set at both ends along the width direction of the socket shell 111, or the card slots 111b can be set at both ends along the length direction and the width direction of the socket shell 111. Other methods are also possible and are not limited here.

[0098] It can be understood that the more the slots 111 b are provided, the more the fixing members 115 are provided, and the more reliably the fixing members 115 fix the socket housing 111 .

[0099] The number of the card slots 111b can be one, two, three, four, five, six, seven or eight, etc., which is not limited here.

[0100] Correspondingly, the number of the fixing members 115 can be one, two, three, four, five, six, seven or eight, etc., which is not limited here.

[0101] Exemplarily, the fixing part 115 is a copper sheet, which is connected to the socket circuit board 112 by welding. At the same time, the socket shell 111 and the socket circuit board 112 are directly connected by glue, thereby achieving sealing between the socket shell 111 and the socket circuit board 112 and enhancing the protective performance.

[0102] The outer wall of the socket housing 111 is provided with a slot 111 b extending in the height direction, which can make the structure of the socket housing 111 more compact and reduce the space occupied by the socket housing 111.

[0103] In some embodiments, the bottom end of the fixing member 115 extends outward and is exposed on the outer wall of the socket housing 111, thereby increasing the working space, facilitating welding the fixing member 115 on the socket circuit board 112, and improving the installation efficiency of the socket housing 111.

[0104] The socket housing 111 fits with the socket circuit board 112 , that is, the bottom end surface of the socket housing 111 fits with the socket circuit board 112 , which is beneficial for fixing the socket housing 111 .

[0105] The fixing member 115 is arranged in the slot 111b and is connected to the socket circuit board 112 to limit the socket shell 111. Through the cooperation between the fixing member 115 and the slot 111b, the fixing member 115 can limit the socket shell 111 along the length direction, width direction or height direction of the socket shell 111, and can also limit the socket shell 111 in any two directions of the length direction, width direction or height direction, and can also limit the socket shell 111 in the length direction, width direction and height direction at the same time.

[0106] At the same time, the fixing member 115 is connected to the socket circuit board 112 , thereby achieving fixation between the socket housing 111 and the socket circuit board 112 .

[0107] Exemplarily, a first clamping portion 111a is provided at both ends of the socket shell 111 along the width direction, a clamping groove 111b is provided at both ends along the length direction of the socket shell 111, and two clamping grooves 111b are provided at both ends along the width direction of the socket shell 111, and the two clamping grooves 111b are respectively located on both sides of the first clamping portion 111a along the length direction, thereby increasing the connection strength between the socket shell 111 and the pin circuit board, and improving the situation in which the side walls at both ends of the socket shell 111 along the width direction are easily elastically deformed due to external force due to their long size and the provision of the first clamping portion 111a, thereby reducing the sealing performance between the socket shell 111 and the socket circuit board 112, so that the connection between the socket shell 111 and the socket circuit board 112 is more reliable.

[0108] Here, the fixing member 115 is set in the card slot 111b. When the fixing member 115 cooperates with the card slot 111b, the fixing member 115 is connected to the socket circuit board 112 to limit the socket shell 111, thereby fixing the socket shell 111 on the socket circuit board 112.

[0109] For some examples, see Figure 1 and Figure 5 , the socket 11 is provided with a fool-proof structure.

[0110] For some examples, see Figure 1 and Figure 5 , the plug 12 is provided with a fool-proof structure.

[0111] It should be noted that the socket 11 may be provided with the anti-fool-proof structure, the plug 12 may be provided with the anti-fool-proof structure, or both the socket 11 and the plug 12 may be provided with the anti-fool-proof structure.

[0112] Specifically, at least part of the side wall of the plug shell 121 extends toward the bottom in the height direction to form a first protrusion 121b, the inner wall of the first protrusion 121b is in contact with the outer wall of the socket shell 111, and the socket shell 111 is away from one end of the first protrusion 121b in the length direction. At least part of the socket shell 111 protrudes outward to form a blocking portion 111c. The blocking portion 111c can prevent the first protrusion 121b from moving downward from the position of the blocking portion 111c in the height direction and from being in contact with the outer wall of the socket shell 111. Interference is formed between the blocking portion 111c and the first protrusion 121b, thereby improving the situation where the plug 12 is inserted upside down into the socket 11, thereby causing electrical failure or circuit abnormality. At the same time, the first protrusion 121b fits against the outer wall of the socket shell 111, which can increase the contact area between the socket shell 111 and the plug shell 121. The socket shell 111 increases the width direction limitation of the plug shell 121 through the first protrusion 121b, thereby strengthening the connection strength between the socket shell 111 and the plug shell 121 and improving the sealing performance between the socket shell 111 and the plug shell 121.

[0113] Therefore, by providing an anti-mock structure between the socket 11 and the plug 12, the plug 12 can be correctly inserted into the socket 11, thereby improving the situation where the plug 12 is inserted into the socket 11 backwards, which may easily lead to electrical failure or circuit abnormality.

[0114] The second aspect of the embodiment of the present application provides a surface mounted socket assembly 20. Figures 8 and 9 The socket assembly 20 includes a top cover 21 and the socket 11 provided in any embodiment of the present application. The top cover 21 is sealed and disposed on the socket housing 111.

[0115] Specifically, a portion of the top cover 21 protrudes toward the bottom end in the height direction to form a flange 121c that mates with the sealing groove 111d of the socket housing 111. When the top cover 21 is placed on the socket housing 111 in the height direction, the flange 121c extends into the sealing groove 111d and abuts against the sealing member 116, thereby achieving a sealed fit between the socket housing 111 and the top cover 21.

[0116] Here, the top cover 21 is sealed on the socket housing 111, so that when there is no plug 12 inserted into the socket 11, the top cover 21 can protect the socket 11, thereby improving the protection performance of the socket 11 when it leaves the factory or when the plug 12 is not inserted, thereby improving the reliability of the socket 11.

[0117] For some examples, see Figures 8 and 9The socket housing 111 is provided with a first clamping portion 111a, at least part of the fastening surface of the first clamping portion 111a is a first curved surface, and the top cover 21 is provided with a third clamping portion 21a, at least part of the fastening surface of the third clamping portion 21a is a third curved surface, and the first clamping portion 111a and the third clamping portion 21a are engaged with each other through the first curved surface and the third curved surface.

[0118] The snap-fitting between the first curved surface and the third curved surface may be a line-to-line contact fit, a surface-to-surface contact fit, or other forms.

[0119] Therefore, the first clamping portion 111a and the third clamping portion 21a are engaged with each other through the first curved surface and the third curved surface, so that the contact area of ​​the engagement is reduced or the engagement amount is reduced, and the top cover 21 is easier to separate from the socket shell 111, which is conducive to pulling the top cover 21 out of the socket 11.
