Description

Technical Field

[0001] The invention belongs to the field of radio frequency connectors, and in particular relates to an inter-board radio frequency connector, a plug and a socket. Background Art

[0002] In the field of communications, inter-board RF connectors are mainly used in the connection of RF modules in devices. Compared with the traditional connection mode of RF components, the structure of inter-board RF connectors is simple, compact and reliable, which is more in line with the development trend of smaller size and lower price in the wireless device market. The reduction in size means saving space, reducing weight and leaving more margin for other system designs.

[0003] Common inter-board RF connectors Figure 1 As shown, the traditional small board-to-board RF connectors are arranged between the boards. Currently, the traditional small board-to-board RF connectors, such as SMP, MMBX and other board-to-board coaxial connectors, can allow limited tolerances and are widely used. This type of board-to-board RF connector mainly includes three components: two sockets 02 respectively mounted on two PCB boards 01 or modules, and an adapter 03 connecting the two sockets 02. Generally, one end of the adapter 03 forms a fixed "semi-permanent" connection with one of the sockets 02 by push-in clamping, and has a large mating retention force, and the other end of the adapter 03 mates with the other socket 02 by sliding in, and the mating retention force is small. At the same time, this end provides a limited tolerance. As shown Figure 2 As shown, the current structure is installed and used by first welding the socket 02 to the PCB board 01 ( Figure 2 a) Install the adapter 03 on the socket 02 at the light hole end ( Figure 2 b), and finally plug the adapter 03 into the socket 02 at the escapement end ( Figure 2 c).

[0004] The problem with the above existing technologies is that since inter-board RF connectors are generally used in multiple channels, the board-to-board RF connectors for each channel require three components, which will undoubtedly lead to high costs for the entire inter-board solution. In addition, the installation process of each board-to-board RF connector is relatively cumbersome, which makes the installation efficiency of the entire multi-channel scenario low. Summary of the invention

[0005] The purpose of the present invention is to provide an inter-board radio frequency connector, a plug and a socket, which saves the adapter through structural optimization, and achieves the functions of three components in the prior art with only two components, the plug and the socket, and makes the installation of the connector simpler, and also reduces the cost of the entire inter-board solution.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is: an inter-board radio frequency connector, comprising a socket, the socket having a socket housing, a radial floating space is provided at the plug-in end of the socket housing, and a socket contact terminal is provided in the socket housing; A plug, used for plugging with the socket, the plug comprising a plug housing, a plug contact terminal being arranged in the plug housing, the plug housing being divided into an integrally formed plug front section, a plug middle section and a plug rear section from the plug-in end to the plug connection end, the plug front section being provided with a radially deformable spring sheet, the plug rear section itself being provided with an elastic structure, or the plug rear section and the plug middle section being connected via an elastic structure; The elastic structure is used to bend radially when the plug and the socket are inserted diagonally, so as to realize radial deflection of the front section and the middle section of the plug, and the radial floating space provides a movable space for the radial deflection of the plug.

[0007] The beneficial effect is that the inter-board RF connector of the present application has only two mating sockets and plugs, and the plug is deformed radially through the radial bending of the elastic structure, so that the front section and the middle section of the plug can be radially deflected, thereby realizing the mating with the socket in the case of oblique insertion. Therefore, the adapter in the prior art can be omitted, the number of parts is reduced, the installation process of the inter-board RF connector is simplified, and the cost of the entire inter-board solution is reduced.

[0008] In addition, in order to ensure the radial deflection of the plug shell, the setting of the radial floating space of the socket shell to the plug end can provide radial activity space for the deflection of the front section of the plug, and the radial deformation spring sheet of the front section of the plug can undergo radial deformation when the plug deflects radially, thereby avoiding interference with the deflection process.

[0009] Furthermore, the radially deformable spring pieces are provided in plurality and are distributed at intervals in the circumferential direction.

[0010] The beneficial effect is that a plurality of radially deformable spring pieces distributed at intervals in the circumferential direction can allow the plug to deflect radially in multiple directions.

[0011] As a first embodiment of the elastic structure, the elastic structure is a sheet-type fence structure, which includes a plurality of elastic sheets evenly distributed along the circumference, the middle part of the elastic sheet is bent toward the center of the plug shell, the front end of the elastic sheet is connected to the middle section of the plug, and the rear end of the elastic sheet is connected to the tail end of the rear section of the plug.

[0012] The beneficial effect is that the sheet-type fence structure is thin in the middle and thick at both ends as a whole. When the plug is inserted diagonally relative to the socket, the sheet-type fence structure is subjected to the extrusion force of the diagonal insertion, so that each elastic sheet has a different degree of elastic deformation, that is, the sheet-type fence structure deflects to one side, thereby driving the radial deflection of the entire plug to ensure that the plug can still be inserted into the socket.

[0013] As a second embodiment of the elastic structure, the elastic structure is a cantilever beam arranged between the middle section of the plug and the rear section of the plug. The cantilever beam is spaced apart along the circumferential direction, and both ends of the cantilever beam are respectively connected to the middle section of the plug and the rear section of the plug. The cantilever beam is bent, and the bending position is far away from the plug shell.

[0014] The beneficial effect is that the bending position of the cantilever beam is far away from the plug housing. When the plug and the socket are inserted diagonally, the elastic structure composed of multiple cantilever beams can make the middle section and the front section of the plug radially swing relative to the rear section of the plug, ensuring that the plug and the socket can be inserted into place.

[0015] As a third embodiment of the elastic structure, the elastic structure is a plurality of corrugated spring pieces, the plurality of corrugated spring pieces serve as the rear section of the plug, one end of the plurality of corrugated spring pieces is connected to the middle section of the plug, and the other end serves as a free end for connection with a PCB board or an adapter module, and the middle part of the corrugated spring piece is bent at least once.

[0016] The beneficial effect is that a plurality of corrugated spring sheets are used as the rear section of the plug, and the middle section of the corrugated spring sheets is bent at least once. When the plug and the socket are inserted diagonally, the elastic structure composed of the plurality of corrugated spring sheets can make the middle section and the front section of the plug radially deflect, thereby ensuring that the plug and the socket can be inserted into place.

[0017] As a fourth embodiment of the elastic structure, the rear section of the plug includes a hollow cylindrical part and a continuous cylindrical part. The hollow cylindrical part is composed of a plurality of spiral spring pieces serving as the elastic structure. The plurality of spiral spring pieces are evenly spaced along the circumference. One end of the spiral spring piece is connected to the end face of the middle section of the plug, and the other end is connected to the end face of the continuous cylinder. The connecting line of the connection positions at both ends of the spiral spring piece is arranged obliquely relative to the axis of the plug housing.

[0018] The beneficial effect is that when the plug and the socket are inserted obliquely, the elastic structure composed of multiple spiral spring sheets can make the middle section and the front section of the plug deflect radially, ensuring that the plug and the socket can be inserted into place.

[0019] As a fifth embodiment of the elastic structure, the rear section of the plug is configured as a coil spring. As the elastic structure, one end of the coil spring is connected to the end face of the middle section of the plug, and the other end forms the tail end of the rear section of the plug, which is used to connect to the PCB board or the adapter module.

[0020] The beneficial effect is that when the plug and the socket are inserted obliquely, the spiral spring as an elastic structure allows the middle section and the front section of the plug to deflect radially, thereby ensuring that the plug and the socket can be inserted into place.

[0021] As a sixth embodiment of the elastic structure, the inner diameter of the rear section of the plug is larger than the outer diameter of the middle section of the plug, and the elastic structure is an S-shaped spring piece distributed along the circumference, one end of the S-shaped spring piece is connected to the end of the middle section of the plug, and the other end is connected to the end of the rear section of the plug.

[0022] The beneficial effect is that when the plug and the socket are inserted obliquely, the S-shaped spring piece as an elastic structure allows the middle section and the front section of the plug to deflect radially, ensuring that the plug and the socket can be inserted into place.

[0023] As a form of implementation of the radial floating space, the plug-in end of the socket housing is provided with an outwardly expanded bell mouth to form the radial floating space.

[0024] The beneficial effect is that a radial floating space realization form which is easy to implement is proposed.

[0025] As an implementation manner, the socket contact terminals in the socket housing are socket pins, and the plug contact terminals in the plug housing are plug jacks.

[0026] The beneficial effect is that a structural form of a socket contact terminal and a plug contact terminal is provided.

[0027] Furthermore, a socket elastic part is provided at the tail end of the plug socket, the socket elastic part adopts the elastic structure to achieve radial bending deformation, and the socket elastic part corresponds to the elastic structure on the plug housing.

[0028] The beneficial effect is that during the radial deflection of the plug, when the tail end of the plug jack is fixed, the plug jack can deflect radially with the plug housing. The position of the jack elastic part corresponds to the elastic structure on the plug housing, which means that the jack elastic part is surrounded by the elastic structure, and when the elastic structure is radially bent, the jack elastic part will bend in the same direction, thereby realizing the radial deflection of the plug jack with the plug housing.

[0029] As another embodiment, the socket contact terminal in the socket housing is a socket jack, and the plug contact terminal in the plug housing is a plug pin, and a flexible component with radial deformation capability is provided at the tail of the plug pin.

[0030] The beneficial effect is that another structural form of the socket contact terminal and the plug contact terminal is provided, and the arrangement of the flexible component can enable the plug pin to deflect radially.

[0031] The beneficial effect of the present invention is that during the inter-board RF connector plug-in process in the prior art, in order to solve the radial floating problem of multiple channels installed simultaneously, under the limitation that the sockets at both ends are fixed on the PCB board, the middle adapter needs to be deflected to meet the contact, so the adapter is necessary.

[0032] The present invention also proposes a plug, comprising a plug shell, in which a plug contact terminal is arranged, a radially deformable spring sheet is arranged at the front end of the plug shell, and an elastic structure is arranged at the rear end of the plug shell. When the plug and the socket are obliquely inserted during insertion, the elastic structure realizes radial deflection of the plug through radial bending.

[0033] The present invention further proposes a socket, comprising a socket housing, wherein a socket contact terminal is arranged in the socket housing, and a radial floating space is arranged at the plug end of the socket housing, wherein the radial floating space provides a movable space for the radial deflection of the above-mentioned plug.

[0034] The present invention improves the structure of the rear section of the plug so that the three-component coordination effect of two sockets and an adapter in the prior art can be achieved by using only the coordination of the plug and the socket, realizing radial floating during the plugging process, eliminating the adapter, reducing the number of parts, simplifying the installation process of the inter-board RF connector, and reducing the cost of the entire inter-board solution.

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the invention in any way.

[0037] Embodiment 1: refer to the attached Figure 3 As shown, an inter-board radio frequency connector includes a socket 1 and a plug 2 that are plugged into each other. The connecting end of the socket 1 is welded and fixed on a PCB board or module, and the connecting end of the plug 2 is welded and fixed on another PCB board or module. The plug-in end of the socket 1 and the plug-in end of the plug 2 are plugged into each other to achieve connection and conduction between the socket contact terminal and the plug contact terminal.

[0038] like Figure 4As shown, the socket 1 includes a socket housing 101, a socket insulator 102 and a socket pin 103. The socket insulator 102 is forcibly installed in the socket housing 101, and the socket pin 103 is forcibly installed in the center of the socket insulator 102. The socket pin 103 serves as the socket contact terminal. The socket pin 103 has barbs, which can be engaged with the socket insulator 102 to prevent the socket pin 103 from moving during the insertion process. The insertion end on the socket housing 101 is configured as an outwardly expanded bell mouth 104, which can form a radial floating space for the radial deflection of the plug 2, so that the plug 2 can float in a limited radial direction, and further, when the plug 2 and the socket 1 are obliquely inserted, they can still be inserted into place. The part where the inner wall of the socket housing 101 connects with the small diameter end of the bell mouth 104 is a straight line segment with a certain length, so that the plug 2 can float axially to a certain extent after being inserted.

[0039] Continue to refer Figure 4 The plug 2 includes a plug housing 201, a plug insulator 202 and a plug socket 203. The plug insulator 202 is forcibly installed in the plug housing 201. The plug socket 203 is a stamped and rolled structural part, which is forcibly installed in the plug insulator 202. The plug socket 203 serves as a plug contact terminal for plugging and connecting with the socket pin 103.

[0040] Further, such as Figure 4 , 5 As shown, the plug housing 201 is divided into a plug front section 201a, a plug middle section 201b, a plug rear section 201c and a fixing plate 201d which are connected in sequence from the plug end to the connection end, and the plug front section 201a, the plug middle section 201b, the plug rear section 201c and the fixing plate 201d are an integrated structure. The plug housing 201 is a rotating body formed by stamping and rolling as a whole, wherein the middle section 201b of the plug is cylindrical, the front section 201a of the plug has a plurality of axial split grooves, which are evenly distributed along the circumference, dividing the front section 201a of the plug into multiple radially deformable elastic sheets that can deform radially, and the rear section 201c of the plug is a sheet-type fence structure, which includes a plurality of elastic sheets evenly distributed along the circumference, the middle part of the elastic sheet is bent toward the center of the plug housing to form a structure with a concave middle part, and the amplitude of the concave middle part of each elastic sheet is the same, the fixing sheet 201d is arranged on the circumferential edge of the rear section 201c of the plug, and has a plurality of fixing sheets 201d, which are spaced apart along the circumferential direction, and the fixing sheets 201d are perpendicular to the center line of the plug housing 201.

[0041] Further, combined with Figure 6As shown, the plug insulator 202 is installed in the middle section 201b of the plug, and the part of the plug jack 203 for plugging with the socket pin 103 is located in the front section 201a of the plug. In addition, an empty slot is provided on the plug insulator 202, so that the impedance of the product can meet the use requirements.

[0042] When the plug 2 is connected and fixed to the corresponding PCB board or module, the fixing piece 201d can be firmly welded to the PCB board or module to ensure that the plug 2 is perpendicular to the PCB board and provide stable support for the entire product during the plug-in process.

[0043] During the process of plug 2 and socket 1 being plugged in, plug 2 and socket 1 are fixed on the PCB. Figure 8 When the plug 2 shown is inserted diagonally relative to the socket 1, the sheet-type fence structure of the rear section 201c of the plug is subjected to the squeezing force of the diagonal insertion, so that each elastic sheet has a different degree of elastic deformation, that is, the sheet-type fence structure appears to deflect toward one side, thereby driving the radial deflection of the entire plug 2 to ensure that the plug hole 203 can still be inserted into place with the socket pin 103. In this process, due to the existence of the axial split groove, the radially deformed spring sheet of the front section 201a of the plug undergoes elastic deformation during the deflection of the plug 2, which can avoid interference with the deflection process of the plug 2. At the same time, the bell mouth 104 of the socket 1 can provide a certain radial floating space for the radial deflection of the plug 2.

[0044] It should be noted that the plug rear section 201c of the sheet-type fence structure can not only meet the radial deflection requirements of the plug 2, but also provide stable support for the entire product, and also enable the product to meet the isolation requirements of the radio frequency characteristics. The elastic sheet in the sheet-type fence structure is concave into an arc, which can make the force of the plug 2 softer when it deflects radially.

[0045] As a preferred solution of this embodiment, when the tail end of the plug jack 203 is fixedly connected to the PCB, it also needs to have a radial deflection function so that it can deflect radially along with the plug housing 201. Figure 7 As shown, in order to achieve this function, the rear end of the plug jack 203 is provided with a jack elastic part 203a, which also adopts the sheet-type fence structure on the plug housing 201, and the jack elastic part 203a is located inside the plug rear section 201c. The front end of the plug jack 203 is a jack contact end 203b, which is used for plugging and contacting with the socket pin 103. The part between the jack elastic part 203a and the jack contact end 203b is cylindrical and is strongly installed in the plug insulator 202.

[0046] In this embodiment, the radial deflection of the plug 2 during oblique insertion is mainly achieved by relying on the elastic deformation of the sheet-type fence structure provided on the rear section 201c of the plug, and then the axial split groove provided on the front section 201a of the plug forms a multi-petal spring sheet to eliminate the interference of the front section 201a of the plug with the radial deflection, and the cooperation of the radial floating space provided by the bell mouth 104 on the socket 1.

[0047] In other embodiments, the sheet-type fence structure may be replaced by other forms of elastic structures to achieve radial deflection of the plug 2. For specific replacement forms, please refer to Examples 2-6.
