Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a connector male socket, a connector and an electronic equipment. Background Art

[0002] With the rapid development of the electronics industry, electronic products are increasingly capable of more functions, and consumers are demanding higher performance from electronic and digital products, such as chip processing power, display screens, and camera pixels. Simultaneously, electronic products are also increasingly requiring more signal lines. As electronic products gain more and more functions, there's a growing emphasis on information exchange between sensors and various functional modules. Currently, these functional modules are often connected using board-to-board (BTB) connectors.

[0003] As the number of functional modules increases, the number of pins in the BTB connector that connects the modules is also gradually increasing. Currently, the double-row, long BTB connector has better space utilization on the market. However, the number of pins is limited. For products with multiple pins, the length of the connector will be increased accordingly, and its strength against external forces will be reduced accordingly, which will limit the overall structural space of the device.

[0004] There are also ring-shaped BTB connectors. As can be seen from the patent application number CN110416788A, titled "A Connector and a Connection Structure for PCB Boards and Peripheral Components," the number of pins in the ring-shaped BTB connector is increased. However, the connector in the above patent is composed of a plurality of stacked BTB connectors of different sizes, and a large spacing distance must be set between the multiple BTB connectors to enable normal connection of the pins (when the spacing between the multiple BTB connectors is small or there is no spacing, the pins cannot be normally connected to the PCB board). Due to the large gap and the existence of excessive gaps, the entire BTB connector is larger in size. However, in order to be able to install enough BTB connectors in the limited space of the electronic device to connect more functional modules, the BTB connector is required to be smaller in size. The two viewpoints are contradictory.

[0005] In related technologies, due to the increase or enhancement of various functions in electronic products, the number of connector pins required for information interaction between sensors and various functional modules has increased. The increase in functional modules has led to limited space inside electronic devices and limited connector volume. There is a problem that existing connectors cannot meet the requirements of increased pins and smaller volume at the same time.

[0006] The above problems need to be solved urgently. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. In the description of the present invention, it should be noted that the term "or" is generally used in the sense of including "and / or" unless the content clearly indicates otherwise.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a magnetic connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three or more, etc., unless otherwise clearly specified and limited.

[0037] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] First, to facilitate understanding of the embodiments of the present invention, some of the terms or nouns involved in the present invention are explained below:

[0039] A connector is a device used to establish a physical or electrical connection between two or more devices, systems, circuits or components. It enables the transmission of signals, data or power through a standardized interface.

[0040] The male socket is the pin part of the connector, usually fixed on a circuit board or cable, and is responsible for inserting into the female socket to establish a connection.

[0041] The female socket is the slot part of the connector, located at the circuit board or device interface, and is used to receive the insertion of the male socket to realize the transmission of circuits or signals.

[0042] To solve the problems existing in the prior art, embodiments of the present application provide a connector male socket, a connector, and an electronic device.

[0043] Example 1

[0044] This embodiment provides a connector male socket, such as Figure 1 As shown, Figure 1 1 is a schematic diagram of the three-dimensional structure of a connector male socket in embodiment 1 of the present invention, the male socket comprising:

[0045] The first fixing bracket 1 includes an inner ring protrusion 12 and an outer ring protrusion 11. The outer ring protrusion 11 is arranged on the periphery of the inner ring protrusion 12. The outermost side of the inner ring protrusion 12 is connected to the innermost side of the outer ring protrusion 11, and the inner ring protrusion 12 and the outer ring protrusion 11 are integrally formed. The first fixing bracket 1 is a rectangular structure; multiple first pin terminals 13 are partially arranged at the two long sides corresponding to the rectangular structure of the inner ring protrusion 12, and partially arranged at the four side lines of the rectangular structure of the outer ring protrusion 11.

[0046] Based on the above structure, an inner ring protrusion 12 and an outer ring protrusion 11 are provided, so that the first fixed bracket 1 forms two annular brackets, and a first pin terminal 13 is provided on both the inner ring protrusion 12 and the outer ring protrusion 11, forming a connector male socket with two circles of connecting pins, effectively achieving the effect of adding connecting pins on the same connector male socket.

[0047] Optionally, the inner ring protrusion 12 and the outer ring protrusion 11 are connected using an integral molding method, making the overall connector male socket smaller in size. The first fixing bracket 1 is also configured as a rectangular parallelepiped structure, which reduces the width of the connector compared to a cube-shaped connector, achieving a smaller size. To accommodate this rectangular parallelepiped structure while retaining connection space for the first pin terminal 13, the first pin terminal 13 is only provided on the long side of the rectangular structure of the inner ring protrusion 12, and is not provided on the wide side of the inner ring protrusion 12. This effectively avoids insufficient space on the wide side of the inner ring protrusion 12 and prevents the protrusion of the first pin terminal 13 on the wide side from affecting the connection space of the first pin terminal 13 on the long side. Providing the first pin terminal 13 only on the long side of the inner ring protrusion 12 effectively balances the volume of the first fixing bracket and the connection space for the first pin terminal 13.

[0048] Optionally, first pin terminals 13 are set on the four side lines of the outer ring protrusion 11, which effectively increases the number of first pin terminals 13, increases the connecting pins on the connector male socket, achieves the effect of connecting more functional modules, and effectively solves the problem of insufficient number of connecting pins.

[0049] Optionally, by providing an inner ring protrusion 12 and an outer ring protrusion 11 on the first fixing bracket 1, two rings of connecting pins are formed, effectively increasing the number of connecting pins on the connector male socket, achieving the effect of connecting more functional modules and effectively solving the problem of insufficient connecting pins. Based on the rectangular parallelepiped structure and the integral connection of the inner ring protrusion 12 and the outer ring protrusion 11, and the provision of the first pin terminal 13 only on the long side of the inner ring protrusion 12, the volume of the entire connector male socket is reduced, effectively achieving the effect of installing multiple connector male sockets in a limited space. This effectively meets the conditions of increasing the number of connector male socket pins and reducing the volume, making it more suitable for connectors in limited spaces.

[0050] In some preferred embodiments, the plurality of first pin terminals 13 are evenly distributed on the first fixing bracket 1 , and the distance between the center lines of two adjacent first pin terminals 13 is 0.4 mm.

[0051] Based on the above structure, multiple first pin terminals 13 are arranged on the long side of the inner ring protrusion 12, and multiple first pin terminals 13 are arranged in parallel on the long side of the inner ring protrusion 12, and the center lines of two adjacent first pin terminals 13 on the same long side are spaced 0.4 mm. This spacing increases the density of the first pin terminals 13 and can reduce the volume of the entire inner ring protrusion 12. At the same time, more first pin terminals 13 can be set on the inner ring protrusion 12 with a smaller volume, effectively achieving the effect of increasing the connecting pins and reducing the volume.

[0052] Optionally, in order to ensure that the first pin terminals 13 set on the surface of the inner ring protrusion 12 will not be connected in series when soldered to other circuit boards, the spacing between the first pin terminals 13 needs to be set to at least 0.35 mm to ensure that adjacent first pin terminals 13 do not affect each other. At the same time, the overall volume and the number of first pin terminals 13 need to be considered, and the center line of two adjacent first pin terminals 13 is set to 0.4 mm to effectively achieve an optimal balance between the connection space and the number of connection pins.

[0053] Optionally, in addition to the inner ring protrusion 12, the first pin terminals 13 distributed on the two long sides of the outer ring protrusion 11 are also arranged in parallel, and the center lines of two adjacent first pin terminals 13 on the same long side are spaced 0.4 mm apart; the first pin terminals 13 distributed on the wide sides of the outer ring protrusion 11 are also arranged in parallel, and the spacing is also 0.4 mm, which effectively achieves the effect of reducing the first fixing bracket 1 while increasing the number of first pin terminals 13.

[0054] In some preferred embodiments, the length of the outer ring protrusion 11 is the product of the number of the plurality of first pin terminals 13 and the first related parameter, plus the second related parameter; and the width of the outer ring protrusion 11 is at least 4.67 mm.

[0055] Based on the above structure, the length and width of the outer ring protrusion 11 directly affect the volume of the entire connector male socket. By limiting the length and width of the outer ring protrusion 11, the volume of the connector male socket can be effectively reduced. Figure 2 FIG. 1 is a schematic diagram of a planar structure of a connector male socket in Example 1 of the present invention, as shown in FIG. Figure 2 As shown, Figure 2The length of area B is the length of the outer ring protrusion 11, and the length of area A is the total length of the first pin terminal 13 after extending out of the outer ring protrusion 11. Based on the length of area A, the length of the first pin terminal 13 extending out of the outer ring protrusion 11 can be determined, that is, the difference between the length of area A and the length of area B, and then divided by 2, to obtain the length of the first pin terminal 13 protruding out of the outer ring protrusion 11.

[0056] Optionally, in order to ensure that multiple first pin terminals 13 can be set on the wide side of the outer ring protrusion 11 without affecting the volume of the connector male seat, the width of the outer ring protrusion 11 needs to be set to at least 4.67 mm. Since the first pin terminal 13 needs to protrude out of the outer ring for a certain length, the width of the entire connector male seat is the width of the outer ring protrusion 11 plus the length of the protruding part of the first pin terminal 13, that is, at least 5.27 mm.

[0057] Optionally, the length of the outer ring protrusion 11 is the product of the number of the plurality of first pin terminals 13 and the first related parameter, plus the second related parameter. In the calculation process of the length of the outer ring protrusion 11, the first related parameter is 0.1, and the second related parameter is 2.82. The length of the outer ring protrusion 11 is specifically calculated as follows:

[0058] L1=(S-12)*0.1+4.02=0.1S-1.2+4.02=0.1S+2.82

[0059] Wherein, S is the number of the first pin terminals 13 , and L1 is the length of the outer ring protrusion 11 .

[0060] Optionally, regarding the different numbers of first pins, there is a phenomenon that the lengths of the outer ring protrusions 11 are different. Several examples of the number of first pins that can be used are listed below, as shown in Table 1. Table 1 is a table showing the relationship between the first pin terminal 13 and the male socket size in Example 1 of the present invention.

[0061] Number of terminals (pins) A B C D 36 5.97 5.19 2.43 4.23 44 6.77 5.99 3.23 5.03 52 7.57 6.79 4.03 5.83 60 8.37 7.59 4.83 6.63 68 9.17 8.39 5.63 7.43 S (S-12)＊0.1+4.1 (S-12)＊0.1+4.02 (S-12)＊0.1-0.62 (S-12)＊0.1+2.77

[0062] In some preferred embodiments, the length of the inner ring protrusion 12 is the product of the number of the plurality of first pin terminals 13 and the first related parameter, minus the third related parameter; and the width of the inner ring protrusion 12 is at least 1.73 mm.

[0063] Based on the above structure, the first pin terminals 13 need to be provided on the long side of the inner ring protrusion 12, and are limited by the length of the outer ring protrusion 11. To ensure that more first pin terminals 13 can be provided on the inner ring protrusion 12 within the volume limit, the length of the inner ring protrusion 12 is combined with the number of first pin terminals 13. The length of the inner ring protrusion 12 is calculated as follows:

[0064] L2=(S-12)*0.1+2.77=0.1S-1.2+2.77=0.1S+1.57

[0065] Wherein, S is the number of the first pin terminals 13, L2 is the length of the inner ring protrusion 12, and 1.57 is the third related parameter.

[0066] Optionally, the first pin terminal 13 provided in the inner ring protrusion 12 extends toward the center position. To ensure that sufficient soldering connection space is reserved for the first pin terminal 13 at the center position and to ensure that the overall volume is small, the first pin terminal 13 is not provided on the wide side of the inner ring protrusion 12, and the first pin terminal 13 is provided only on the long side of the inner ring protrusion 12, effectively reducing the width of the inner ring protrusion 12, thereby reducing the volume of the entire connector male socket. Since the first pin terminal 13 provided at the inner ring protrusion 12 needs to extend toward the center position, when the first pin terminal 13 is provided on both the long side and the wide side, the first pin terminal 13 on the wide side may affect the first pin terminal 13 near the wide side on the long side, resulting in insufficient space for the first pin terminals 13 at both ends of the long side. Therefore, in order to ensure sufficient soldering space for the first pin terminal 13 on the long side, the first pin terminal 13 may not be provided on the wide side.

[0067] Optionally, since the first pin terminal 13 does not need to be set at the wide side of the inner ring protrusion 12, the width of the inner ring protrusion 12 can be reduced, and the wide side of the inner ring protrusion 12 is set to 1.73 mm, which can ensure that there is enough space for the first pin terminal 13 on the inner ring protrusion 12 and can also ensure that the overall volume of the entire connecting socket is small.

[0068] In some preferred embodiments, it also includes: a first through hole 14, which is arranged at the center of the inner ring protrusion 12; the first pin terminals 13 arranged at the two long sides corresponding to the rectangular structure of the inner ring protrusion 12 both extend toward the first through hole 14, and the first pin terminals 13 at the two long sides are spaced apart and are not connected to each other.

[0069] Based on the above structure, the first pin terminal 13 in the inner ring protrusion 12 extends toward its center position to form a pin connection point. Therefore, a first through hole 14 needs to be set at the center position of the inner ring protrusion 12 so that after the first pin terminal 13 is set, there is space for connection with other components.

[0070] Optionally, in order to ensure that both rows of first pin terminals 13 at the long side of the inner ring protrusion 12 can be used, the two rows of first pin terminals 13 need to be separated by a certain distance. When connecting one row of first pin terminals 13, it will not affect the use of the other row of first pin terminals 13. At the same time, there will be no signal transmission errors caused by contact connection, and accurate signal transmission is effectively achieved.

[0071] In some preferred embodiments, the spacing distance between the first pin terminals 13 located at two long sides of the inner ring protrusion 12 is at least 1.13 mm.

[0072] Based on the above structure, to ensure that the first pin terminals 13 on the two long sides of the inner ring protrusion 12 do not interfere with each other, the minimum distance between the two rows of first pin terminals 13 is set to 1.13 mm. This 1.13 mm distance between the two rows of first pin terminals 13 ensures that they do not interfere with each other when connecting other components. Specifically, when soldering one row of first pin terminals 13, the first pin terminals 13 in the other row will not be soldered together, preventing signal series connection, effectively ensuring the normal use of the inner ring protrusion 12 in the connector male socket.

[0073] Furthermore, the outward extension distance of the first pin terminals 13 located on the long sides of the outer ring protrusion 11 can be determined. Since the first pin terminals 13 on one of the long sides of the outer ring protrusion 11 extend outward by 0.3 mm, the first pin terminals 13 on the inner ring protrusion 12 also need to extend inward by 0.3 mm. The first pin terminals 13 on one row of the long sides of the inner ring protrusion 12 need to extend inward by 0.3 mm, so the first pin terminals 13 on both rows of the long sides need to extend inward by 0.6 mm. Since the width of the inner ring protrusion 12 is set at 1.73 mm, the minimum spacing between the two rows of first pin terminals 13 is determined to be 1.13 mm.

[0074] In some preferred embodiments, the present invention further comprises: reinforcing positioning posts 15 , which are arranged on the outer ring protrusion 11 and located at the four corners of the outer ring protrusion 11 .

[0075] Based on the above structure, the male socket of the connector is composed of two annular structures. When the annular structure is squeezed, deformation may occur at the outer ring protrusion 11. It is necessary to set reinforced positioning columns 15 at the four corners of the outer ring protrusion 11. The first pin terminal 13 is not set at the reinforced positioning column 15. The corners of the reinforced positioning column 15 close to the external environment are set to an arc shape, and the radius of the arc shape must be less than or equal to 0.16 mm.

[0076] Optionally, the corners of the reinforcing positioning post 15 can be configured as arcs to facilitate insertion of the male and female connectors when mating. In the case of right angles, the force applied to the corners is horizontal, requiring downward pressure to connect the male and female connectors. In the case of arcs, the force applied to the corners is dispersed and spread in multiple directions, making it easier for the male and female connectors to connect.

[0077] Optionally, the radius of the arc is set to less than or equal to 0.16 mm, so that the arc is smaller, the area of the reinforced positioning column 15 is increased, the strength of the reinforced positioning column 15 is effectively improved, and the deformation resistance of the male seat when squeezed is improved, thereby avoiding damage to the connector male seat during use.

[0078] In some preferred embodiments, it also includes: a reinforcing protrusion 16, which is integrally connected to the reinforcing positioning column 15, and the reinforcing protrusion 16 is a protrusion from the outer ring protrusion 11 to the inner ring protrusion 12; the shortest distance between the reinforcing protrusion 16 and the inner ring protrusion 12 is the first distance, and the shortest distance between the outer ring protrusion 11 and the inner ring protrusion 12 is the second distance, and the first distance is smaller than the second distance.

[0079] Based on the above structure, the reinforcing positioning column 15 can play a role in enhancing the strength of the male socket of the connector. However, since the male socket of the connector needs to be used in conjunction with the female socket, in order to ensure that it is not easy to separate during use, that is, to ensure that the degree of crimping is relatively tight and the electrical connection between the male socket and the female socket is more stable, a reinforcing protrusion 16 can be provided. The reinforcing protrusion 16 is based on the reinforcing positioning column 15 and extends from the outer ring protrusion 11 to the inner ring protrusion 12 to form a protrusion structure toward the inner ring protrusion 12, so that after the reinforcing protrusion 16 is combined with the reinforcing positioning column 15, the entire structure is an irregular shape.

[0080] Optionally, since the entire structure is irregular, when the male and female sockets cooperate with each other, the reinforcing protrusion 16 will press against the female socket, making it difficult for the male and female sockets to separate after cooperation, and will not shake easily to cause poor contact, thereby effectively achieving the stability of the male socket connection.

[0081] In some preferred embodiments, the first fixing bracket 1 is made of insulating plastic material.

[0082] Based on the above structure, a first pin terminal 13 is provided on the first fixing bracket 1 to ensure that the first pin terminal 13 can conduct electricity to form signal transmission, and the first fixing bracket 1 outside the first pin terminal 13 is insulated to avoid the first fixing bracket 1 affecting the signal transmission, thereby effectively realizing the accuracy and stability of the connector male socket transmission.

[0083] Optionally, plastic materials are easier to obtain, which reduces costs. It should be noted that the first fixing bracket 1 needs to be made of hard plastic material to ensure the overall hardness of the first fixing bracket 1 and to prevent it from being deformed by squeezing during use.

[0084] Example 2

[0085] According to another aspect of an embodiment of the present invention, a connector is provided, comprising any one of the connector male and female connectors. Figure 3: is a schematic diagram of the three-dimensional structure of a connector female socket in embodiment 2 of the present invention, as shown in FIG. Figure 3 As shown, the connector socket includes a second fixing bracket 2; the second fixing bracket 2 includes an inner ring groove 21 and an outer ring groove 22, the outer ring groove 22 is arranged on the periphery of the inner ring groove 21, the outermost side of the inner ring groove 21 is connected to the innermost side of the outer ring groove 22, and the inner ring groove 21 and the outer ring groove 22 are integrally formed, and the second fixing bracket 2 is a rectangular parallelepiped structure; the inner ring groove 21 and the inner ring protrusion 12 match each other, and the outer ring groove 22 and the outer ring protrusion 11 match each other; a plurality of second pin terminals 23, some of which are arranged at the two long sides corresponding to the rectangular structure of the inner ring groove 21, and some are arranged at the four side lines of the rectangular structure of the outer ring groove 22.

[0086] Based on the above structure, the connector includes a male socket and a female socket, which cooperate with each other by plugging. There is an outer ring protrusion 11 and an inner ring protrusion 12 in the male socket, and an outer ring groove 22 and an inner ring groove 21 in the female socket. The outer ring groove 22 is matched with the outer ring protrusion 11, and the inner ring groove 21 is matched with the inner ring protrusion 12, so that the male socket and the female socket are plugged together to form a complete connector.

[0087] Optionally, a second pin terminal 23 is provided on the female socket, and the second pin terminal 23 cooperates with the first pin terminal 13 to transmit the electrical signal on the second pin terminal 23 to the first pin terminal 13, and then to other components, thereby effectively realizing signal transmission.

[0088] Optionally, the second pin terminal 23 provided on the female socket is embedded in the second fixing bracket 2, and only a portion connected to the first pin terminal 13 is exposed to the external environment, and the rest of the portion is hidden in the second fixing bracket 2. When the first pin terminal 13 and the second pin terminal 23 are plugged together, the first pin terminal 13 is in an extended state without any support, and will undergo a slight deformation when it contacts the second pin terminal 23, causing the first pin terminal 13 to be pressed against the second pin terminal 23. Since the second pin terminal 23 is surrounded by the second fixing bracket 2, it is not easy to deform. Therefore, when the first pin terminal 13 exerts pressure on the second pin terminal 23, a reaction force can also be formed by the second pin terminal 23 exerting on the first pin terminal 13, thereby achieving a fixed connection between the first pin terminal 13 and the second pin terminal 23.

[0089] In some preferred embodiments, the positions of the plurality of second pin terminals 23 and the plurality of first pin terminals 13 correspond one to one and match each other, and the plurality of second pin terminals 23 are electrically connected to the plurality of first pin terminals 13 after contact.

[0090] Based on the above structure, the number of the second pin terminals 23 is the same as the number of the first pin terminals 13, and the second pin terminals 23 and the first pin terminals 13 are in a one-to-one correspondence. When the male socket and the female socket are plugged together, one first pin terminal 13 corresponds to one second pin terminal 23, and the two cooperate with each other to realize the transmission of the signal from the second pin terminal 23 to the first pin terminal 13.

[0091] In some preferred embodiments, the plurality of first pin terminals 13 and the plurality of second pin terminals 23 are made of conductive copper; and the second fixing bracket 2 is made of insulating plastic.

[0092] Based on the above structure, to ensure signal transmission and stability, both the first pin terminal 13 and the second pin terminal 23 are configured to be conductive, enabling signal transmission between them. Furthermore, copper is relatively inexpensive among conductive metals, so using conductive copper for both the first pin terminal 13 and the second pin terminal 23 effectively reduces their cost.

[0093] Optionally, copper's conductivity is second only to silver (the cost of silver is 100 times that of copper). For every ampere of current transmitted, the resistance of copper conductors is 60% lower than that of aluminum, and the energy loss is lower. Using copper pin terminals can reduce heat generation when the male and female sockets are working, and extend the life of the connector. In addition, copper has high ductility and can be drawn into 0.01mm filaments or rolled into 0.001mm sheets. This flexibility allows the terminal pins to be easily bent into complex shapes (such as L-type and U-type), avoiding stress fractures during plugging and unplugging. At the same time, the thermal conductivity of copper is three times that of iron. When current passes through, the locally increased temperature can be quickly conducted away, which avoids the problem of signal loss caused by the soaring contact resistance due to overheating and softening of the terminal pins.

[0094] In some preferred embodiments, the second through hole 24 is further provided at the center of the inner groove 21 ; and the minimum distance at the edge of the second through hole 24 is greater than 0.6 mm.

[0095] Based on the above structure, Figure 4 : is a schematic diagram of the planar structure of a connector female socket in embodiment 2 of the present invention, as shown in FIG. Figure 4 As shown, the length of the outer ring groove 22 of the female seat matches the length of the outer ring protrusion 11 of the male seat. Figure 4 The length of the N region is the length of the outer groove 22, the length of the M region is the total length of the second pin terminal 23 after it extends out of the outer groove 22. The length of the E region is the length of the inner groove 21, and the length of the F region is the length of the second through hole 24.

[0096] Optionally, regarding the different numbers of second pins, there is a phenomenon that the lengths of the outer ring groove 22 are different. Several examples of the number of second pins that can be used are listed as shown in Table 2 below. Table 2 is a table of the relationship between the second pin terminal 23 and the female socket size in Example 2 of the present invention.

[0097] Number of terminals (pins) M N F E 36 6.5 6.42 1.78 5.17 44 7.3 7.22 2.58 5.97 52 8.1 8.02 3.38 6.77 60 8.8 8.72 4.18 7.57 68 9.6 9.52 4.98 8.37 S (S-12)*0.1+4.1 (S-12)*0.1+4.02 (S-12)*0.1-0.62 (S-12)*0.1+2.77

[0098] Optionally, at least 0.6 mm needs to be reserved at the inner ring groove 21 to avoid interference between the two rows of pins when the second pin is connected to other devices, resulting in deviation in the transmission signal. Sufficient space is reserved in the middle of the inner ring groove 21 to effectively realize the normal use of the inner ring pins.

[0099] In some preferred embodiments, it also includes: a reinforcement groove 25, which is arranged at the outer ring groove 22 and located at the four corners of the outer ring groove 22; the reinforcement groove 25 matches the reinforcement positioning column 15 and the reinforcement protrusion 16, and the volume of the reinforcement groove 25 is equal to the sum of the volumes of the reinforcement positioning column 15 and the reinforcement protrusion 16.

[0100] Based on the above structure, the reinforcing groove 25 matches the reinforcing positioning column 15 and the reinforcing protrusion 16, and the male seat and the female seat are fixedly connected by plugging. Under the action of the reinforcing groove 25, the corners of the female seat are supported and will not be deformed during the extrusion process, effectively realizing the close combination of the male seat and the female seat.

[0101] Optionally, there is a structure on the reinforcing groove 25 that cooperates with the reinforcing protrusion 16, so that the reinforcing protrusion 16 can be embedded inside, avoiding the female seat and the male seat from shaking with each other after being combined. At the same time, the structure of the reinforcing groove 25 and the reinforcing positioning column 15 is strengthened, effectively avoiding deformation of the male seat or the female seat.

[0102] In some preferred embodiments, the width of the plurality of first pin terminals 13 is greater than the width of the plurality of second pin terminals 23 .

[0103] Based on the above structure, since the first pin terminal 13 extends outward from the first fixing bracket 1, the first fixing bracket 1 has a relatively small supporting effect on the first pin terminal 13, and the first pin terminal 13 will be deformed when mated with the second pin terminal 23. In order to ensure that the degree of deformation is low and there is a mutual pressing force, the width of the first pin terminal 13 needs to be increased to prevent the first pin terminal 13 from being bent after deformation and unable to be restored.

[0104] Optionally, since the second pin terminal 23 is arranged inside the second fixing bracket 2, the second fixing bracket 2 supports the second pin terminal 23, so the deformation degree of the second pin terminal 23 is small, and the width of the second pin terminal 23 can be reduced to save material usage.

[0105] In some preferred embodiments, Figure 5 This is a schematic diagram of the plug-in structure of a connector male and female socket in embodiment 2 of the present invention, as shown in FIG. Figure 5 As shown, the female connector and the male connector cooperate with each other. After cooperation, the maximum gap between the reinforcing groove 25 and the reinforcing positioning column 15 is 0.015 mm, and the maximum gap between the inner ring protrusion 12 and the inner ring groove 21 is 0.035 mm.

[0106] Based on the above structure, after the female socket and the male socket are plugged together, the height difference between the two needs to be reduced as much as possible, that is, the first pin terminal 13 and the second pin terminal 23 are pressed together as much as possible to effectively ensure the stability of the connector signal transmission.

[0107] Optionally, the maximum gap between the top surface of the reinforcing groove 25 and the bottom surface of the reinforcing positioning post 15 is 0.015 mm, that is, a gap of 0.015 mm exists between the two. This is to ensure that the reinforcing groove 25 and the reinforcing positioning post 15 can fit together infinitely. By tightening the reinforcing groove 25 and the reinforcing positioning post 15, the mutual repulsive force between the first pin terminal 13 and the second pin terminal 23 can be effectively prevented from squeezing the male and female connectors apart.

[0108] Optionally, the outer ring protrusion 11 and the outer ring groove 22 are connected by a reinforced groove 25 and a reinforced positioning column 15, and the mutual repulsive force is partially offset by the friction force after the two are plugged in. However, since the volume of the inner ring protrusion 12 and the inner ring groove 21 is relatively small, it is not suitable to set the reinforced groove 25 structure. Therefore, the mutual repulsive force in the inner ring protrusion 12 and the inner ring groove 21 cannot be offset. There may be a situation where the first pin terminal 13 and the second pin terminal 23 press against each other, causing the male and female sockets to separate from each other a little bit. However, the maximum separation gap in the inner ring shall not exceed 0.035 mm, which effectively ensures the stability of the inner ring connection and the stability of the signal transmission between the male and female sockets.

Figure 6 FIG. 1 is a structural diagram of an electronic device connected to a connector in Example 3 of the present invention, such as Figure 6 As shown, the male connector is electrically connected to the first circuit board 3 through the first pin terminal 13 and the first fixing bracket 1, and the female connector is electrically connected to the second circuit board 4 through the second pin terminal 23 and the second fixing bracket 2.

[0111] Based on the above structure, one end of the female socket of the connector is connected to the PCB circuit board, and the other end is connected to the male socket. The end of the male socket away from the female socket is connected to the flexible circuit board. Various components can be connected on the PCB circuit board to realize the transmission of signals of various components to the connector through the PCB circuit board, and then transmitted from the connector to the flexible circuit board, realizing stable signal transmission.

[0112] At the same time, a steel sheet reinforcement plate can be set on the other side of the flexible circuit board to ensure a stable connection between the flexible circuit board and the connector male socket, and at the same time achieve the effect of static electricity conduction.
