Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Currently, to increase the number of terminals of a board-to-board connector, it is generally performed to increase the length of the board-to-board connector. However, as the length of the board-to-board connector increases, it may affect the assembly of the board-to-board connector on the electronic device.

Based on this, the inventors have conducted extensive studies on board-to-board connectors of electronic devices. Among them, the research of the inventor includes: how to increase the number of terminals of the board-to-board connector, how to enable the board-to-board connector with the increased number of terminals to be assembled to an electronic apparatus, and the like. After a lot of repeated comparison and research, the inventor further studied how to design a board-to-board connector that increases the number of terminals and can be assembled to an electronic device, and thus proposed a solution of the embodiment of the present application.

Referring to fig. 1, an electronic device 100 is provided in the present embodiment, where the electronic device 100 may be, but is not limited to, an electronic device such as a mobile phone, a tablet computer, and a smart watch. The electronic device 100 of the present embodiment is described by taking a mobile phone as an example.

The electronic device 100 includes a circuit board 110 and a board-to-board connector 200, the board-to-board connector 200 being connected with the circuit board 110. The electronic device 100 further includes a functional module (not shown), and the board-to-board connector 200 is electrically connected between the circuit board 110 and the functional module to implement data transmission between the circuit board 110 and the functional module. It should be noted that the functional module includes, but is not limited to, a camera module, a sensor, a display screen, and the like, and the specific structure of the functional module may refer to the prior art and is not described herein.

Referring to fig. 2, the board-to-board connector 200 includes a first connector 210, a second connector 230, and a connector holder 250, wherein the connector holder 250 is connected between the first connector 210 and the second connector 230, and the first connector 210 and the second connector 230 are connected by the connector holder 250. Wherein the first connector 210 and the second connector 230 can be connected in different directions with respect to the connector holder 250.

Specifically, as shown in fig. 2, an extension a1 in the length direction of the first connector 210 and an extension a2 in the length direction of the second connector 230 intersect at the position of the connector holder 250 (the intersection is indicated by O). At this time, the first connector 210 and the second connector 230 form an angle therebetween, the angle having the intersection O as a vertex of the angle and a1 and a2 as sides of the angle. Wherein the overall length of the board-to-board connector 200 can be adjusted by adjusting the angle of the included angle formed between the first connector 210 and the second connector 230.

It should be noted that the length of the first connector 210 is the size of the longer side of the first connector 210, the length of the second connector 230 is the size of the longer side of the second connector 230, and the overall size of the board-to-board connector 200 is the size of the longer side of the board-to-board connector 200. The "longer side" is a line segment in the geometric figure formed by the outer contours of the first connector 210, the second connector 230, and the board-to-board connector 200, respectively.

For example, when the first connector 210 and the second connector 230 are connected in the same direction with respect to the connector holder 250, i.e., the angle formed between the first connector 210 and the second connector 230 is 180 ° (as shown in fig. 2), the length of the board-to-board connector 200 is equal to the sum of the lengths of the first connector 210 and the second connector 230. Further, as can be seen from the geometric principle, when the included angle formed between the first connector 210 and the second connector 230 is smaller than 180 °, the length of the board-to-board connector 200 is smaller than the sum of the lengths of the first connector 210 and the second connector 230, and therefore, the length of the board-to-board connector 200 can be adjusted by adjusting the included angle formed between the first connector 210 and the second connector 230.

Referring to fig. 3, the first connector 210 includes a mounting member 211, a connection terminal 213 and two catching arms 215, the connection terminal 213 is disposed on the mounting member 211, and the two catching arms 215 are connected to the mounting member 211. The mounting member 211 is substantially a rectangular parallelepiped, and the mounting member 211 is used for forming an external surface of the first connector 210 and for mounting the connection terminal 213 and the two holding arms 215 to achieve the related functions of the first connector 210.

In the present embodiment, the connection terminal 213 needs to have good conductivity and mechanical strength, so that when the connection terminal 213 is electrically connected between the circuit board 110 and the functional module, data transmission between the circuit board 110 and the functional module can be realized. One end of the connection terminal 213 is exposed relative to the mounting member 211 for connecting with the functional module. In one embodiment, the connection terminal 213 is substantially in a multi-fold curved shape to provide an electrical connection end in a limited space, and the two ends of the connection terminal 213 can be oriented according to the positions of the circuit board 110 and the function module, so that the connection terminal 213 is suitable for the circuit board 110 and the function module at different positions. As an embodiment, the connection terminal 213 may be a wire-shaped metal structure, a sheet-shaped metal structure, or the like having a certain elasticity.

Further, the number of the connection terminals 213 may be plural, and the plurality of connection terminals 213 are divided into two rows and are respectively mounted on two sides of the mounting member 211. The mounting member 211 can protect the plurality of connection terminals 213, and the plurality of connection terminals 213 are mounted on the mounting member 211, so that the plurality of connection terminals 213 can be modularized, thereby facilitating the connection between the plurality of connection terminals 213 and the circuit board 110.

In some embodiments, the mounting member 211 may have a mounting groove (not shown) for mounting the connection terminal 213, so as to increase the connection stability between the connection terminal 213 and the mounting member 211 and prevent the connection terminal 213 from falling off from the mounting member 211 under an external force to affect the use of the first connector 210. In other embodiments, the connection terminal 213 may be mounted to the mounting member 211 by welding, so as to improve the connection stability between the connection terminal 213 and the mounting member 211.

It should be noted that, in the actual production process, the number of the connection terminals 213 is about 20 to 40, that is, the first connector 210 has about 20 to 40 electrical connection terminals for connecting with the functional module. In actual manufacturing, the connection terminals 213 are respectively disposed on both sides of the mounting member 211, the number of the connection terminals 213 on one side is 10 to 20, and the length of the first connector 210 is suitable.

The two catching arms 215 are disposed at the same end of the mounting member 211 and are used for connecting with the connector holder 250, thereby realizing the connection of the first connector 210 with the connector holder 250. In the present embodiment, two catching arms 215 are disposed at the same end of the mounting member 211 to form a catching end for catching the connector holder 250. For example, the two catching arms 215 protrude in the same direction with respect to the mounting 211 to form a space for receiving (and catching) the connector holder 250. The retaining arms 215 may be made of an elastic material to retain the two opposite sides of the first retainer 2511 by a deforming force. It should be noted that, in the present embodiment, the mounting member 211 is a rectangular parallelepiped structure, the "end" is used to describe the shorter side of the mounting member 211, and the "side" is used to describe the longer side of the mounting member 211.

Referring to fig. 3, the holding arm 215 may include a strap portion 2150, a guide portion 2151, and a clamp portion 2153, wherein the guide portion 2151 is connected between the clamp portion 2153 and the strap portion 2150. The strap 2150 is generally elongated and is disposed generally along the length of the mount 211 for strapping to the connector holder 250. The guide portion 2151 is formed in a substantially bar shape, is connected to one end of the overlapping portion 2150, and is disposed substantially obliquely with respect to the overlapping portion 2150. Further, the angle between the guide portion 2151 and the overlapping portion 2150 is an obtuse angle, and one end thereof away from the overlapping portion 210 extends toward the side of the first connector 210 close to the connector holder 250 to form an inclined guide structure for cooperating with the connector holder 250, thereby improving the convenience of the detachable assembly between the first connector 210 and the connector holder 250.

The clamping portion 2153 is substantially bar-shaped, and has one end connected to an end of the guide portion 2151 away from the overlapping portion 2150 and the other end for connection with the connector holder 250. Thus, the clamping portion 2153, the overlapping portion 2150, and the guiding portion 2151 together form a substantially triangular structure, and together define a hollow area 2101 (as shown in fig. 3), so that the holding arm 215 has stable structural strength and high elastic deformation capability, which is beneficial to improving the assembly convenience and the assembly structural strength of the first connector 210 and the connector bracket 250. One side of the clamping portion 2153 may be provided with clamping protrusions (not shown), in this embodiment, the two clamping arms 215 are disposed opposite to each other, and the clamping protrusions of the two clamping portions 2153 are disposed opposite to each other, so as to clamp the connector holder 250 between the two clamping protrusions.

In some embodiments, the number of the catching arms 215 may be at least two, for example, four catching arms 215 are provided, and two catching arms 215 are respectively provided at two ends of the connector holder 250, so that stable clamping of two opposite sides of the connector holder 250 can be achieved. When there are three catching arms 215, two catching arms 215 may be disposed on one side of the mounting member 211, and the other catching arm 215 is disposed on the other side of the mounting member 211, wherein a plurality of catching arms 215 may be disposed on one side of the connector bracket 250 that is easy to fall off relative to the mounting member 211 during actual use, so as to improve the holding stability of the catching arms 215 to the connector bracket 250.

In the present embodiment, the structure of the second connector 230 is substantially the same as that of the first connector 210, and the second connector 230 also includes a mount 231, a connection terminal 233, and two chucking arms 235. The structure of the second connector 230 can refer to the structure of the first connector 210, and is not described herein. The second connector 230 also has 20-40 connection terminals 233, so that the board-to-board connector 200 formed by connecting the first connector 210 and the second connector 230 has about 40-80 electrical connection terminals for connecting with the functional module, which can better satisfy the data transmission requirement between the electronic device 100 and the functional module.

Referring to fig. 4, the connector holder 250 includes a first holder 251, a second holder 253, and a connecting member 255, wherein the first holder 251 is connected to the first connector 210, and the second holder 253 is connected to the second connector 230. The connecting member 255 is connected between the first bracket 251 and the second bracket 253, wherein the first bracket 251 and the second bracket 253 are adjustably connected to each other by the connecting member 255.

In this embodiment, the connecting member 255 is a pivot 2551, and the first bracket 251 is pivotally connected to the second bracket 253 via the pivot 2551. The first bracket 251 and the second bracket 253 can rotate relative to the pivot 2551, so that the included angle between the first bracket 251 and the second bracket 253 changes. Since the first bracket 251 is connected to the first connector 210 and the second connector 230 is connected to the second connector 230, when the angle between the first bracket 251 and the second bracket 253 is changed, the angle formed between the first connector 210 and the second connector 230 is changed. In some embodiments, the pivot shaft 2551 may be integrally formed with the first bracket 251, and the second bracket 253 is provided with a mounting groove (not shown) corresponding to the pivot shaft 2551, and the pivot shaft 2551 is received in the mounting groove to connect the first bracket 251 and the second bracket 253.

In one embodiment, when the first connector 210 and the second connector 230 are substantially rectangular parallelepiped structures, the angle formed between the first connector 210 and the second connector 230 may be an angle formed by the axis of symmetry of the first connector 210 and the axis of symmetry of the second connector 230 intersecting the pivot 2551.

With continued reference to fig. 4, the first bracket 251 includes a first holder 2511 and a first positioning element 2513 connected to the first holder 2511, and the first connector 210 is mounted on the first holder 2511. The first retainer 2511 is substantially plate-shaped, and the two catching arms 215 are clamped at two opposite sides of the first retainer 2511, so that the first connector 210 and the first retainer 2511 are connected.

As an embodiment, the two retaining arms 215 are clamped at two opposite ends of the first retainer 2511, and can be detachably connected, so as to replace the first retainer 2511 or the first connector 210, thereby prolonging the service life of the board-to-board connector 200. For example, as shown in fig. 4, the two opposite ends of the first retainer 2511 are respectively provided with a retaining groove 2507, when the first connector 210 is connected with the first retainer 2511, the two retaining arms 215 can be directly matched with the retaining grooves 2507 on the two sides of the first retainer 2511, so that the overlapping portion 2150 is overlapped with the first retainer 2511, the guide portion 2151 is embedded into the retaining grooves 2507, and the engaging portion 2153 is engaged with the first retainer 2511. The clamping portions 2153 clamped at two sides of the first holder 2511 clamp the first holder 2511 together. In other embodiments, the retaining arms 215 may be sequentially inserted into the retaining grooves 2507 through the inclined guide structures of the guide portions 2151, while the overlapping portions 2150 are overlapped with the first holder 2511 and the catching portions 2153 are caught on the first holder 2511.

Further, the first retainer 2511 comprises a retaining body 2501 and a fitting portion 2503 connected to the retaining body 2501, wherein the retaining body 2501 is substantially plate-shaped, and the fitting portion 2503 is disposed at one end of the retaining body 2501 so as to be connected to the first positioning element 2513. As an embodiment, the engaging portion 2503 may be provided with an engaging groove (not shown), and the first positioning element 2513 may be provided with a structure capable of being inserted into the engaging groove, so that the first positioning element 2513 is connected to the engaging portion 2503 by being inserted into the engaging groove. At this time, the connection of the first holder 2511 and the first positioning element 2513 is a detachable connection, so as to replace the first holder 2511 and/or the first positioning element 2513 which are damaged.

In some embodiments, there are two fitting portions 2503, and two fitting portions 2503 are respectively disposed at two opposite ends of the holding body 2501, i.e., the first positioning element 2513 is selectively connected to either end of the holding body 2501. In this case, two first positioning members 2513 may be provided, and the two first positioning members 2513 are connected to the two engagement portions 2503, respectively. Further, there are two second connectors 230, and the two second connectors 230 are connected to the two first positioning elements 2513 through the two second brackets 253. At this time, the board-to-board connector 200 includes a first connector 210 and two second connectors 230, and the board-to-board connector 200 has approximately 60 to 120 electrical connection terminals for connecting with the functional module.

In other embodiments, the first retainer 2511 and the first retainer 2513 are integrally formed, so that the structure of the fitting portion 2503 can be omitted, and the first retainer 2511 and the first retainer 2513 can be integrally connected by injection molding, thereby improving the connection relationship between the first retainer 2511 and the first retainer 2513.

In the present embodiment, the first bracket 251 further includes a fitting element 2515, and the fitting element 2515 is connected between the first holder 2511 and the first positioning element 2513. Wherein, the fitting element 2515 is connected with the fitting portion 2503 to realize the connection of the fitting element 2515 and the first holding element 2511. In the present embodiment, fitting member 2515 has a substantially strip-like plate shape, first positioning member 2513 is a positioning post, and the positioning post is provided to protrude from the surface of fitting member 2515.

The second bracket 253 includes a second retainer 2531 and a second positioning member 2533 connected to the second retainer 2531, the second connector 230 is mounted to the second retainer 2531, and the first positioning member 2513 is adjustably connected to the second positioning member 2533. The structure of the second retainer 2531 is similar to that of the first retainer 2511, and reference may be made to the structure of the first retainer 2511, which is not described herein again. As an embodiment, the second retainer 2531 and the second positioning member 2533 may be integrally formed.

Referring to fig. 5, the second positioning member 2533 is provided with a positioning slot 2505, and the positioning column is accommodated in the positioning slot 2505, so as to realize the connection and positioning of the first bracket 251 and the second bracket 253. In this embodiment, there are a plurality of positioning slots 2505, the positioning slots 2505 are disposed at intervals on the second positioning member 2533, and the positioning post is selectively received in any one of the positioning slots 2505. Further, an end of the second positioning member 2533 away from the second holding member 2531 is configured as an arc, and a plurality of positioning slots 2505 are spaced along the arc, so that when the positioning posts are received in the positioning slots 2505, the second connector 230 and the first connector 210 form different included angles. For example, referring to fig. 2 and 5, the positioning posts are connected to different positioning slots 2505, and the included angle formed between the first connector 210 and the second connector 230 is different, and the board-to-board connector 200 has different lengths.

In some embodiments, as shown in fig. 6, the mating element 2515 can be a bent structure. For example, the fitting member 2515 has a structure extending in the longitudinal direction of the first connector 210 and bent and extended in the width direction of the first connector 210. Further, by adjusting the connection of the first positioning member 2513 and the second positioning member 2533, the first connector 210 and the second connector 230 may assume a juxtaposed arrangement (a1 and a2 do not intersect). At this time, the length of the board-to-board connector 200 is substantially equal to the size of the longer side of the first connector 210, so that the board-to-board connector 200 has a smaller length to fit the inner space of the electronic apparatus 100.

According to the board-to-board connector 200 and the electronic device 100 provided by the embodiment of the application, the first connector 210 and the second connector 230 are connected through the connector bracket 250, the first bracket 251 and the second bracket 253 are adjustably connected with each other through the connecting piece 255, and the first connector 210 and the second connector 230 are also respectively driven to be connected in an angle, so that the number of the connecting terminals 213 of the board-to-board connector 200 can be increased, and the board-to-board connector 200 is adapted to the inner space of the electronic device 100.
