[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. The embodiments described below and the features in the embodiments can be combined with each other without conflict.
[0061] In the related art, a circumferential annular groove is arranged on a base body of a female socket, a sealing ring is fixed in the groove, and then the base body of the female socket is arranged in a seat body, so that a gap between the base body of the female socket and the seat body is sealed by the sealing ring. A male socket is also sealed by a sealing ring in the same way, so that the number of sealing rings is increased, and the cost of the socket is increased. In addition, female pins in the female socket and male pins in the male socket are both machined, and the female pins and the male pins are both gold-plated as a whole by barrel plating, so that the area of gold plating is large, and the cost of the female socket and the male socket is increased.
[0062] In order to overcome the defects in the related art, the application provides a female socket and a male socket. In the female socket, a first sealing structure is arranged on the outer wall surface of a first base body, so that the first base body and a first seat body are sealingly connected. In the male socket, a second sealing structure is arranged on the outer wall surface of a second base body, so that the second base body and a second seat body are sealingly connected. Thus, the number of sealing rings in the female socket and the male socket is reduced, and the cost is reduced. In addition, the female pin in the female socket and the male pin in the male socket can be locally plated, and only the coupling parts of the female pin and the male pin are plated, so that the area of the plating layer is reduced, and the cost is reduced.
[0063] The content of the application will be described in detail below with reference to the drawings, so that those skilled in the art can more clearly and specifically understand the content of the application.
[0064] As shown in Figure 1 and Figure 3 , the female socket 10 includes a first seat body 100, a first base body 110 and a first coupling member 120. The first seat body 100 has a receiving hole 101.
[0065] In some embodiments, as shown in Figure 1 and Figure 3 , the outer wall surface of the first seat body 100 has a thread structure arranged circumferentially, which is used to connect with a nut having a matching internal thread. The nut and the first seat body 100 can be sealingly connected by a sealing ring. When the female socket 10 needs to be fixed on a device or a panel of a device, a hole can be formed on the device or the panel of the device, and the first seat body 100, which has been sleeved with a sealing ring, is connected with the nut through the thread. At this time, the sealing ring is used to seal the gap between the device and the female socket 10.
[0066] As shown in Figure 1 and Figure 3 , in the female socket 10, the outer contour of the first base body 110 matches the receiving hole 101. The outer wall surface of the first base body 110 has a first sealing structure 111. Exemplarily, the first sealing structure 111 is a plurality of sealing protrusions arranged in a ring shape along the circumference of the first base body 110. The first sealing structure 111 and the first base body 110 are an injection molding integrated structure. The first base body 110 is arranged in the receiving hole 101, and the first sealing structure 111 is sealingly connected with the hole wall of the receiving hole 101.
[0067] In some embodiments, as shown in Figure 1 and Figure 3As shown, the first sealing structure 111 on the outer wall surface of the first base body 110 is a plurality of sealing protrusions arranged in a ring shape along the circumference of the first base body 110, so that the first base body 110 and the first seat body 100 in the female end socket 10 can achieve a higher level of waterproof and dustproof effect. In addition, the first sealing structure 111 and the first base body 110 are an injection molding integrated structure, which is simple to manufacture and can make the first sealing structure 111 itself have a certain elasticity and can deform. During manufacturing, the sealing protrusions of the first sealing structure 111 are higher than the outer wall surface of the first base body 110, so that the first sealing structure 111 and the hole wall of the accommodating hole 101 are in interference fit sealing connection, thereby achieving a higher level of sealing effect. At the same time, the first sealing structure 111 replaces the sealing ring, thereby reducing the number of sealing rings used and reducing the cost of the female end socket 10.
[0068] As shown in Figure 1 and Figure 3 , in the female end socket 10, the first base body 110 has a through hole 112 through which the first coupling piece 120 passes, the first coupling piece 120 passes through the through hole 112 and is fixed relative to the first base body 110, and the first coupling piece 120 is configured to be electrically coupled with the second coupling piece 220 on the male end socket 20 matched with the female end socket 10.
[0069] In some embodiments, as shown in Figure 1 and Figure 3 , an annular protrusion is arranged on the redundant area 123 of the first coupling piece 120, so that the first coupling piece 120 is fixed by interference fit with the through hole 112 and the first base body 110, preventing the first coupling piece 120 from moving along the axial direction of the through hole 112.
[0070] The first coupling piece 120 is a stamping coupling piece, which is manufactured by stamping process. One end of the first coupling piece 120 is a coupling end 121 with a contact hole, and the other end is a solid connection end 127. The inner and outer surfaces of the coupling end 121 have conductive coatings, and the connection end 127 is not provided with a conductive coating. The coupling end 121 is configured to be electrically coupled with the second coupling piece 220 on the male end socket 20 matched with the female end socket 10.
[0071] In some embodiments, the conductive coating of the first coupling piece 120 is a gold plating process. The stamping process allows the first coupling piece 120 to be locally plated in batches, thereby controlling the plating of the inner and outer surfaces of the coupling end 121 of the first coupling piece 120, and the connection end 127 is not plated. In this way, the plating area is reduced, the processing cost of the first coupling piece 120 is reduced, and the cost of the female end socket 10 is reduced.
[0072] In addition, the first coupling piece 120 is a rotary structure with a diameter of 0.6-1 mm.
[0073] In some embodiments, the first coupling member 120 can be made with a size of 0.6mm-1mm, for example, 0.6mm, 0.7mm, 0.8mm, 1mm, etc. by a stamping process, the coupling end 121 of the first coupling member 120 is formed by roll forming, so as to control the distance between the through holes 112 of the two adjacent first coupling members 120 in the first base body 110, and keep the distance between the two adjacent through holes 112 at a proper thickness, so as to avoid the influence of the too thin thickness on the fixation of the first coupling member 120 on the first base body 110.
[0074] The coupling end 121 of the first coupling member 120 has a contact hole, the axial direction of the contact hole is the same as the extension direction of the first coupling member 120, and the contact hole includes a contact area 122 and a redundant area 123 connected in sequence along the axial direction of the contact hole, and the redundant area 123 is located on the side close to the connecting end 127.
[0075] In some embodiments, as shown in Figure 1 and Figure 5 The redundant area 123 is located on the other end of the contact area 122 for coupling connection with the second coupling member 220 of the male socket 20, and provides a redundant space for the coupling depth of the second coupling member 220 of the male socket 20, which can increase the coupling area of the first coupling member 120 and the second coupling member 220, and provide an error for the installation process of the second coupling member 220 in the second base body 210.
[0076] The isolation structure 124 is arranged between the contact area 122 and the redundant area 123, and is used for isolating and sealing the contact area 122 and the redundant area 123.
[0077] In some embodiments, as shown in Figure 3 and Figure 5 The first seat body 100 has a cavity inside the tail end of the first base body 110, i.e. the direction of the connecting end 127 of the first coupling member 120, and the cavity is filled by an injection process, so as to seal the tail end of the female socket 10 integrally, so that the female socket 10 can achieve a higher level of dustproof and waterproof effect. In the injection process, in order to avoid the glue flowing to the contact area 122 of the first coupling member 120 through the gap between the first coupling member 120 and the first base body 110 and the middle hole formed by the roll forming of the coupling end 121 of the first coupling member 120, which affects the electrical coupling performance of the second coupling member 220 of the male socket 20, the isolation structure 124 is arranged between the contact area 122 and the redundant area 123.
[0078] The isolation structure 124 includes at least two isolation baffles 125, and the at least two isolation baffles 125 are arranged in the axial direction of the contact hole between the contact area 122 and the redundant area 123.
[0079] In some embodiments, as shown in Figure 3 The reason why the isolation structure 124 includes at least two isolation barriers 125 is to avoid the gap between the single isolation barrier 125 and the first coupling member 120 due to the processing error, and the at least two isolation barriers 125 can play the role of one for many, so that the glue is completely isolated outside the contact area 122 during the glue injection process, and the influence of the glue flowing to the contact area 122 on the electrical coupling between the second coupling member 220 of the male socket 20 is completely eliminated.
[0080] The first coupling member 120 has a relief gap 126 between the coupling end 121 and the connecting end 127.
[0081] In some embodiments, as shown in Figure 3 and Figure 5 The first coupling member 120 can be processed by a profiled material stamping process, that is, the coupling end 121 and the connecting end 127 of the first coupling member 120 can be processed by materials with different thicknesses, and the relief gap 126 is arranged between the coupling end 121 and the connecting end 127, which can prevent the materials from interfering with each other during the stamping process.
[0082] The connecting end 127 of the first coupling member 120 has a first positioning structure 1271 on the outer wall surface, which is used for mutual positioning with a second positioning structure on the circuit board to position the connecting end 127 and the circuit board. Exemplarily, the first positioning structure 1271 is a positioning step.
[0083] In some embodiments, as shown in Figure 3 and Figure 5 The first positioning structure 1271 is arranged on the connecting end 127, and the second positioning structure is located on the circuit board, which can be a round hole, a square hole, etc. opened on the circuit board, and cooperates with the connecting end 127 of the first coupling member 120 and the positioning step thereon to insert the connecting end 127 of the first coupling member 120 into the hole opened on the circuit, so that the first positioning structure 1271 is attached to the edge of the hole of the circuit board and clamps the first coupling member 120, and the first coupling member 120 cannot be further inserted, so that the first positioning structure 1271 and the circuit board are mutually positioned.
[0084] In some embodiments, as shown in Figure 3 and Figure 5 The first positioning structure 1271 is a positioning step, which is attached to the edge of the hole opened on the circuit board, so that the first coupling member 120 is clamped to realize mutual positioning of the first coupling member 120 and the circuit board.
[0085] In addition, the coupling end 121 of the first coupling member 120 is in a rotary structure, and the connecting end 127 is in a plate structure, or the coupling end 121 and the connecting end 127 are both in a rotary structure.
[0086] In some embodiments, the female socket 10 is connected to other components or devices through the connecting end 127 of the first coupling member 120. For example, the female socket is welded to a circuit board, the coupling end 121 and the connecting end 127 of the first coupling member 120 are both in a rotary structure, or the female socket is welded to a wire, the coupling end 121 of the first coupling member 120 is in a rotary structure, and the connecting end 127 is in a plate structure or a rotary structure.
[0087] The end of the connecting end 127 of the first coupling member 120 has at least one of a notch and a bending structure, and at least one of the profile surface of the notch and the profile surface of the bending structure is formed as a solder cup structure 1272.
[0088] In some embodiments, as shown in Figure 6 the coupling end 121 of the first coupling member 120 is in a rotary structure, the connecting end 127 is in a plate structure, the end of the connecting end 127 of the first coupling member 120 has a solder cup structure 1272 formed by a bending structure, the solder cup structure 1272 is configured to be welded to a wire, and the contact area between the connecting end 127 of the first coupling member 120 and the wire is increased by the solder cup structure, and the reliability of welding is increased.
[0089] In other embodiments, the coupling end 121 and the connecting end 127 of the first coupling member 120 are both in a rotary structure, an arc-shaped notch is arranged on the connecting end 127 to form a solder cup structure 1272, and the contact area between the connecting end 127 of the first coupling member 120 and the wire is increased.
[0090] To prevent the first coupling member 120 from rotating in the first base body 110, the first base body 110 has a through hole 112 through which the first coupling member 120 passes, the hole wall of the through hole 112 has a first limiting structure 1121, and the outer wall surface of the first coupling member 120 has a second limiting structure 1273. When the first coupling member 120 is arranged in the through hole 112, the first limiting structure 1121 and the second limiting structure 1273 are matched to limit the rotation of the first coupling member 120 around the axis direction thereof, wherein the first limiting structure 1121 is one of a limiting groove and a limiting protrusion, and the second limiting structure 1273 is the other of the limiting groove and the limiting protrusion.
[0091] In some embodiments, as shown in Figure 9As shown, the connecting end 127 of the first coupling member 120 is a plate structure, a first limiting structure 1121, i.e. two axial limiting grooves, is formed on the inner wall surface of the through hole 112 in the first base body 110, and a second limiting structure 1273, i.e. two limiting protrusions, is arranged on the connecting end 127 of the first coupling member 120, so that the two axial grooves and the two protrusions are matched, thereby limiting the rotation of the first coupling member 120 in the through hole 112 of the first base body 110, and the opening direction of the welding cup structure 1272 can be limited to face the outer wall surface of the female socket 10.
[0092] In some other embodiments, the first limiting structure 1121 can be a limiting protrusion, and the second limiting structure 1273 can be a matching limiting groove, thereby limiting the rotation of the first coupling member 120 in the through hole 112 of the first base body 110, and controlling the orientation of the welding cup structure 1272.
[0093] In some embodiments, the connecting end 127 of the first coupling member 120 in the female socket 10 is a curved structure with a bending angle of 90°-180°, such as 90°, 120°, 150°, etc., so that the insertion direction of the female socket 10 and the male socket 20 has multiple choices, and the application scenarios are more extensive.
[0094] As shown in Figure 2 and Figure 4 The male socket 20 includes a second seat body 200, a second base body 210 and a second coupling member 220, wherein the second seat body 200 has a receiving cavity 201.
[0095] In some embodiments, as shown in Figure 2 and Figure 4 The outer wall surface of the second seat body 200 has a thread structure arranged circumferentially, which is used to connect with a nut having a matching internal thread. The nut and the second seat body 200 can be sealed by a sealing ring. When the male socket 20 needs to be fixed on a device or a panel of a device, a hole can be formed on the device or the panel of the device, and the second seat body 200, which has been sleeved with a sealing ring, is inserted through the hole and connected with the nut by threads. At this time, the sealing ring seals the gap between the device and the male socket 20.
[0096] As shown in Figure 2 and Figure 4 In the male socket 20, the outer contour of the second base body 210 matches the receiving cavity 201, the outer wall surface of the second base body 210 has a second sealing structure 211, which is exemplarily a plurality of sealing protrusions arranged annularly along the circumference of the second base body 210. The second sealing structure 211 and the second base body 210 are an integral structure, the second base body 210 is arranged in the receiving cavity 201, and the second sealing structure 211 is sealingly connected with the cavity wall of the receiving cavity 201.
[0097] In some embodiments, as shown in Figure 2 and Figure 4 , the second sealing structure 211 on the outer wall surface of the second base 210 is a plurality of sealing bosses arranged in a ring shape along the circumference of the second base 210, so that the second base 210 in the male socket 20 and the second seat body 200 can achieve a higher level of waterproof and dustproof effect. In addition, the second sealing structure 211 and the second base 210 are an injection molding integrated structure, the manufacturing method is simple, and the second sealing structure 211 itself has a certain elasticity and can deform. In the manufacturing process, the sealing boss of the second sealing structure 211 is higher than the outer wall surface of the second base 210, so that the second sealing structure 211 and the hole wall of the accommodating cavity 201 are in interference fit sealing connection, thereby achieving a higher level of sealing effect. At the same time, the second sealing structure 211 replaces the sealing ring, thereby reducing the number of sealing rings used and reducing the cost of the male socket 20.
[0098] As shown in Figure 2 and Figure 4 , the second coupling member 220 is arranged along the extension direction of the accommodating cavity 201. The second coupling member 220 penetrates the second base 210 and is fixed relative to the second base 210. The second coupling member 220 is configured to be electrically coupled with the first coupling member 120 on the female socket 10 matched with the male socket 20. The second coupling member 220 and the second base 210 are an integrated structure.
[0099] In some embodiments, an annular protrusion is arranged on the second coupling member 220 to prevent the second coupling member 220 from moving axially in the second base 210, as shown in Figure 4 and Figure 7 , an embossing structure can also be arranged on the second coupling member 220 to prevent the second coupling member 220 from rotating in the second base 210.
[0100] In some embodiments, as shown in Figure 2 , by using an insert injection molding process, the finished product of the second coupling member 220 and the second base 210 is an integrated structure, thereby reducing the step of installing the second coupling member 220 into the second base 210, reducing the installation process, and saving time and cost.
[0101] One end of the second coupling member 220 is a coupling conductive end 221, and the other end is a fixed end 222. The surface of the coupling conductive end 221 has a conductive coating, and the surface of the fixed end 222 does not have a conductive coating. The coupling conductive end 221 is configured to be plugged into and electrically coupled with the coupling end 121 of the first coupling member 120 on the female socket 10 matched with the male socket 20.
[0102] In some embodiments, the second coupling member 220 can be made by a stamping process, or by a machining process, and then by insert injection molding process, so that the second coupling member 220 and the second base body 210 are integrated into one structure. The embossed structure of the second coupling member 220 can also be machined by a machining process. In addition, the second coupling member 220 made by a machining process can also be partially plated.
[0103] In some embodiments, the conductive coating of the second coupling member 220 is a gold plating process. The second coupling member 220 can be partially plated in batches, so as to control the gold plating of the inner and outer surfaces of the coupling conductive end 221 of the second coupling member 220, and the fixed end 222 is not plated. In this way, the gold plating area is reduced, the processing cost of the second coupling member 220 is reduced, and the cost of the male socket 20 is reduced.
[0104] In other embodiments, the second base body 210 and the second coupling member 220 in the male socket 20 are independent individuals, and the finished product is not an integrated structure, as shown in Figure 8 In some embodiments, the coupling conductive end 221 of the second coupling member 220 is a rotary structure, and the fixed end 222 is a plate structure, or as shown in Figure 7 In some embodiments, the coupling conductive end 221 of the second coupling member 220 is a rotary structure, and the fixed end 222 is also a rotary structure.
[0105] In some embodiments, the coupling conductive end 221 of the second coupling member 220 is a rotary structure, and the fixed end 222 is a plate structure, or as shown in
[0106] In some embodiments, the second sealing structure 211 and the second base body 210 are not injection molded into an integrated structure, as shown in Figure 8As shown, the second seat body 200 has a cavity inside the tail end of the second base 210, i.e. the fixed end 222 of the second coupling member 220, and the tail end of the male socket 20 is integrally sealed by filling the cavity with glue in a glue injection process, so that the male socket 20 can achieve a higher level of dustproof and waterproof effect. In the glue injection process, in order to avoid the glue flowing to the coupling conductive end 221 of the second coupling member 220 through the gap between the second coupling member 220 and the second base 210 and the intermediate hole formed by the roll forming of the coupling conductive end 221, affecting the electrical coupling performance with the first coupling member 120 of the female socket 10, an isolation structure is arranged in the coupling conductive end 221, wherein the isolation structure includes at least two isolation baffles, and the at least two isolation baffles are arranged in the coupling conductive end 221 along the axial direction of the contact hole. The reason for arranging at least two isolation baffles is to avoid a gap between a single isolation baffle and the second coupling member 220 due to processing errors, and at least two isolation baffles can play the role of one for multiple backups, so that the glue is completely isolated outside the coupling conductive end 221 during the glue injection process, completely eliminating the influence of the glue flowing to the coupling conductive end 221 on the electrical coupling with the first coupling member 120 of the female socket 10.
[0107] The outer wall surface of the fixed end 222 of the second coupling member 220 has a first positioning part 2221, which is used for mutual positioning with a second positioning part on the circuit board, so as to position the fixed end 222 and the corresponding circuit board.
[0108] In some embodiments, as shown in Figure 4 and Figure 7 , the first positioning part 2221 is arranged on the fixed end 222 and can be a positioning step, and the second positioning part is arranged on the circuit board and can be a round hole, a square hole or the like formed on the circuit board. The fixed end 222 of the second coupling member 220 is inserted into the hole formed on the circuit board, so that the positioning step of the first positioning part 2221 is in contact with the edge of the hole of the circuit board and clamps the second coupling member 220, and the second coupling member 220 cannot be further inserted, so as to position the first positioning part 2221 and the circuit board relative to each other.
[0109] In some embodiments, the end of the fixed end 222 of the second coupling member 220 has at least one of a notch and a bending structure, and at least one of the profile surface of the notch and the profile surface of the bending structure is formed as a solder cup structure, as shown in Figure 8 The solder cup structure is configured to be welded with a wire, and the contact area between the fixed end 222 of the second coupling member 220 and the wire is increased by the solder cup structure, and the reliability of welding is increased.
[0110] In other embodiments, the coupling conductive end 221 and the fixed end 222 of the second coupling member 220 are both rotary structures, thereby providing an arc-shaped notch on the fixed end 222 to form a welding cup structure, thereby increasing the contact area between the fixed end 222 of the second coupling member 220 and the wire.
[0111] In some embodiments, the second sealing structure 211 and the second base 210 are not injection molded integral structures. To prevent the second coupling member 220 from rotating in the second base 210, a first limiting structure 1121 is provided on the through hole of the second base 210, and a second limiting structure 1273 is provided on the outer wall surface of the second coupling member 220. When the second coupling member 220 passes through the through hole, the first limiting structure 1121 and the second limiting structure 1273 match to limit the rotation of the second coupling member 220 about its own axis. The first limiting structure 1121 is one of a limiting groove and a limiting protrusion, and the second limiting structure 1273 is the other of a limiting groove and a limiting protrusion.
[0112] In some embodiments, the fixed end 222 of the second coupling member 220 in the male socket 20 is a bent structure with a bending angle of 90°-180°, such as 90°, 120°, 150°, etc., so that the insertion direction of the male socket 20 and the female socket 10 can be selected in multiple ways, and the application scenarios are more extensive.
[0113] This application embodiment also provides a connector, which includes the above-mentioned female socket 10 and male socket 20, and the female socket 10 and male socket 20 are connected together.
[0114] In some embodiments, such as Figure 3 As shown, the inner wall surface of the first seat 100 in the female socket 10 that contacts the male socket 20 can be provided with a threaded structure, which matches the thread on the outer wall surface of the second seat 200 in the male socket 20. When the female socket 10 and the male socket 20 are plugged in, the first seat 100 and the second seat 200 are threadedly connected, and the first coupling member 120 and the second coupling member 220 are coupled and energized.
