Description

Technical Field

[0001] This utility model relates to the field of modular circuit board technology, specifically a modular circuit board. Background Technology

[0002] Modular circuit boards are printed circuit boards that achieve multifunctional integration through various modular designs or material combinations. Their core lies in integrating multiple circuit board units, different materials (such as flexible and rigid substrates), or special structural components to improve space utilization, mechanical performance, and functional adaptability. New energy vehicles require modular circuit boards in their energy storage devices to facilitate the connection of different module units on the circuit board.

[0003] Modular circuit boards integrate different modules onto different circuit boards, and then multiple circuit boards are spliced ​​together. The advantage is that different modules can be replaced as needed, and when a module is damaged, it can be directly replaced for maintenance, reducing the cost of replacing the entire circuit board. Two circuit boards are connected by connectors. However, after the connectors are mated, the stability of the two circuit boards can cause the connectors to wobble, which can lead to unstable connector connections or loose circuit connections, resulting in different modules on the circuit board being unable to connect. Summary of the Invention

[0004] The purpose of this utility model is to provide a combined circuit board that uses a tensioning component to ensure a tight fit between the plug and socket, preventing loose connections. At the same time, a locking component is used to increase the stability between the socket and plug and the circuit motherboard and circuit daughterboard, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined circuit board, comprising:

[0006] Motherboard and daughterboard;

[0007] A socket is provided at the outer edge of the circuit motherboard, and a plug is provided at one end of the circuit daughterboard. The socket and the plug are electrically connected to the circuits on the circuit motherboard and the circuit daughterboard, respectively. The plug and the socket are in close contact and connected to the circuit.

[0008] A tensioning component is provided between the plug and the socket to prevent the plug from separating from the socket and causing a loose connection in the circuit.

[0009] A locking assembly is provided between the socket and the circuit motherboard and the plug and the circuit daughterboard. The locking assembly prevents the socket and plug from being bent and disconnected from the circuit of the circuit motherboard and the circuit daughterboard.

[0010] Preferably, the tensioning assembly includes circular holes at both ends of the plug and perpendicular to the socket. A fixing ring is fixedly embedded in the circular hole. A movable post is movably disposed in the fixing ring. A threaded post is fixed at one end of the movable post. A threaded hole for cooperating with the threaded post is opened at the end of the socket away from the circuit motherboard. The other end of the movable post extends through to the outside of the fixing ring and is fixed with a knob post. An anti-reverse structure is also provided between the movable post and the fixing ring.

[0011] Preferably, the locking assembly includes a hexagonal through hole and a circular through hole corresponding to each other on the outside of the plug and socket. A locking bolt is provided at one end of the hexagonal through hole, and one end of the locking bolt is engaged with the hexagonal through hole. The other end of the locking bolt extends through the circuit motherboard and the circuit daughterboard into the circular through hole and is threaded with a locking nut.

[0012] Preferably, the anti-reverse structure includes a limiting ring fixed to the outside of the movable column, and the end of the limiting ring facing the fixed ring is provided with an anti-slip protrusion that interlocks and restricts each other.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention connects the circuit board and the circuit daughterboard through the mating of a plug and socket. A tensioning component is provided between the plug and socket to ensure a tight fit and prevent separation, which could lead to loose connections in the internal circuitry.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figures 1-6 The illustrated modular circuit board includes:

[0028] Motherboard 1 and daughterboard 2;

[0029] A socket 3 is provided at the outer edge of the circuit motherboard 1, and a plug 4 is provided at one end of the circuit daughterboard 2. The socket 3 and the plug 4 are electrically connected to the circuits on the circuit motherboard 1 and the circuit daughterboard 2 respectively. The plug 4 and the socket 3 are in close contact and connected to the circuit.

[0030] A tensioning component 5 is provided between the plug 4 and the socket 3. The tensioning component 5 prevents the plug 4 from separating from the socket 3, which would cause a loose connection in the circuit.

[0031] A locking component 6 is provided between the socket 3 and the circuit motherboard 1 and the plug 4 and the circuit daughterboard 2. The locking component 6 prevents the circuit of the socket 3 and plug 4 from being bent and disconnected from the circuit of the circuit motherboard 1 and the circuit daughterboard 2. The cooperation between the plug 4 and the socket 3 is a common means of circuit board connection and is a mature existing technology. This article will not go into detail about the circuit content of this structure.

[0032] The connection between the circuit board 1 and the circuit daughter board 2 is achieved by the mating of the plug 4 and the socket 3. Then, a tensioning component 5 is set between the plug 4 and the socket 3 to ensure that the plug 4 and the socket 3 fit tightly and prevent the plug 4 and the socket 3 from separating, which would cause a loose connection in the circuit inside the plug 4 and the socket 3. At the same time, a locking component 6 is set on the plug 4 and the socket 3 to ensure a stable connection with the circuit board 1 and the circuit daughter board 2, and to prevent the circuit daughter board 2 from shaking between the circuit board 1 and the circuit board 1. This would cause the connection between the plug 4 and the socket 3 and the circuit board 1 and the circuit daughter board 2 to shake and cause a short circuit. This avoids the problem of short circuits in traditional combined circuit boards.

[0033] Among them, such as Figure 3-5 As shown:

[0034] The tensioning assembly 5 includes round holes 51 at both ends of the plug 4 and perpendicular to the socket 3. A fixing ring 52 is fixedly embedded in the round hole 51. A movable post 53 is movably disposed in the fixing ring 52. A threaded post 54 is fixed at one end of the movable post 53. A threaded hole 55 that mates with the threaded post 54 is opened at the end of the socket 3 away from the circuit motherboard 1. The other end of the movable post 53 extends to the outside of the fixing ring 52 and is fixed with a knob post 56. An anti-reverse structure 7 is also provided between the movable post 53 and the fixing ring 52. By rotating the knob post 56, the movable post 53 and the threaded post 54 are driven to rotate. Then, the threaded post 54, in conjunction with the threaded hole 55, fits the plug 4 against the outside of the socket 3, preventing gaps from forming between the plug 4 and the socket 3, which would cause a loose connection in the internal circuit of the plug 4 and the socket 3.

[0035] Furthermore, such as Figure 3 As shown:

[0036] The locking assembly 6 includes a hexagonal through hole 61 and a circular through hole 62 corresponding to the outer sides of the plug 4 and the socket 3. A locking bolt 63 is provided at one end of the hexagonal through hole 61, and one end of the locking bolt 63 is engaged with the hexagonal through hole 61. The other end of the locking bolt 63 extends through the circuit motherboard 1 and the circuit daughterboard 2 into the circular through hole 62 and is threadedly connected to a locking nut 64. Through the cooperation of the locking nut 64 and the locking bolt 63, the plug 4 and the socket 3 are stably installed on the outer sides of the circuit motherboard 1 and the circuit daughterboard 2, respectively, to prevent the plug 4 and the socket 3 from shaking with the circuit daughterboard 2 and the circuit motherboard 1 after they are connected, which would cause the circuit to be disconnected.

[0037] Preferred, such as Figure 4-5 As shown:

[0038] The anti-reverse structure 7 includes a limiting ring 71 fixed to the outside of the movable column 53. The end of the limiting ring 71 facing the fixed ring 52 is provided with an anti-slip protrusion 72 that interlocks and restricts each other. The anti-slip protrusion 72 prevents the movable column 53 from rotating inside the fixed ring 52 without external force intervention. This is to prevent the threaded column 54 from rotating in the threaded hole 55, which would cause a gap between the plug 4 and the socket 3 and affect the circuit connection.

[0039] It is worth noting that, such as Figure 2 As shown:

[0040] A flexible rubber plug 8 is installed at the end of the plug 4 away from the circuit board 2. A groove 9 is provided at the end of the socket 3 near the plug 4. The rubber plug 8 is squeezed and locked into the groove 9. Through the cooperation between the rubber plug 8 and the groove 9, the friction between the rubber plug 8 and the inner wall of the groove 9 is used to increase the stability between the plug 4 and the socket 3 and prevent the plug 4 from separating from the socket 3.

[0041] In a further preferred embodiment, such as Figure 4 As shown:

[0042] An anti-slip strip 10 is provided on the outer side of the knob post 56. An external groove 11 is provided at the end of the knob post 56 away from the movable post 53. The anti-slip strip 10 increases the friction between the hand and the knob post 56, making it easier to rotate the knob post 56. At the same time, the external groove 11 is used to connect with tools, so that when it is inconvenient to operate the knob post 56 by hand, tools can be used to rotate the knob post 56.

[0043] In addition, such as Figure 6 As shown:

[0044] Both the motherboard 1 and the daughterboard 2 have storage slots 12 at their edges. One side of the socket 3 and the plug 4 is located in the storage slot 12. The storage slot 12 is designed to allow the socket 3 and the plug 4 to be easily attached to the outside of the motherboard 1 and the daughterboard 2. This prevents the socket 3 and the plug 4 from being subjected to uneven force on both sides when they are shaken, which would increase the shaking amplitude of the plug 4 and the socket 3 and reduce the stability of the plug 4 and the socket 3.

[0045] In practical use, plug 4 and socket 3 are respectively snapped into the storage slots 12 of circuit sub-board 2 and circuit motherboard 1. Then, using locking bolts 63 and locking nuts 64, plug 4 and socket 3 are installed on circuit sub-board 2 and circuit motherboard 1. Then, circuit sub-board 2 is placed in the corresponding position on circuit motherboard 1, and plug 4 and socket 3 are connected. At this time, rubber plug 8 is inserted into plug groove 9. At the same time, the knob column 56 is rotated, so that the knob column 56 drives the threaded column 54 to rotate through the movable column 53. The threaded column 54 rotates in the threaded hole 55, and plug 4 and socket 3 are brought into contact. When the limiting ring 71 is in contact with the fixing ring 52, the anti-slip protrusions 72 are engaged with each other, which can prevent the knob column 56 from reversing, improve the stability between plug 4 and socket 3, and realize the circuit connection between circuit sub-board 2 and circuit motherboard 1.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
