[0038] Please refer to Figures 1 to 3 This embodiment provides a housing 100, in which a circuit board 210 is fixedly installed. The housing 100 can be used for electronic equipment 200, such as electric meters, relays, sockets and other electronic products. Of course, it is not limited to this. The housing 100 can also be used to install other plate-like components other than the circuit board 210. In addition to being used in electronic products, the housing 100 can also be used in other housing assembly structures, which is not specifically limited here.

[0039] The present embodiment provides a housing 100, including a first housing 110 and a second housing 150, wherein a rib 120 is disposed on the first housing 110. A clamping block 160 is disposed on the second housing 150, and the clamping block 160 is used to clamp a circuit board 210. The first housing 110 and the second housing 150 are connected, and the rib 120 is used to press the circuit board 210, and the rib 120 is located on a side of the clamping block 160 away from the circuit board 210. Due to the provision of the rib 120, the circuit board 210 can be pressed and held to prevent the circuit board 210 from shifting or warping and deforming. At the same time, the clamping block 160 can be limited to prevent the deformation of the clamping block 160 from being too large, resulting in the detachment of the clamping block 160 and the circuit board 210. The housing 100 can improve the stability and reliability of the circuit board 210 during installation and transportation. In addition, the housing 100 has a simple structure, does not require additional parts such as screws, is easy to assemble, and is conducive to improving assembly efficiency.

[0040] In this embodiment, the housing 100 is applied to a single-phase electric meter, the first housing 110 is used as the front housing of the electric meter, and the second housing 150 is used as the rear housing of the electric meter. The first housing 110 and the second housing 150 cover each other to form an accommodation space, and the accommodation space is used to accommodate the circuit board 210 and other necessary components. The housing 100 fixes and protects the circuit board 210 and other components in the accommodation space.

[0041] Optionally, the first housing 110 is provided with a hook 130, and the second housing 150 is provided with a protrusion 170, and the hook 130 and the protrusion 170 cooperate to achieve a snap connection between the first housing 110 and the second housing 150, which is convenient for assembly.

[0042] The perimeter frame 120 includes a first pressing portion 121, a stopper portion 123, and a second pressing portion 125 connected in sequence, and the first pressing portion 121 and the second pressing portion 125 are arranged opposite to each other. The first pressing portion 121 and the second pressing portion 125 are respectively located on both sides of the clamping block 160, and are used to press the circuit board 210 to prevent the circuit board 210 from warping and deforming. The stopper portion 123 is located on the side of the clamping block 160 away from the circuit board 210, and limits the clamping block 160 to prevent the clamping block 160 from being separated from the circuit board 210 due to excessive deformation of the clamping block 160.

[0043] At least one of the first pressing portion 121, the stopper portion 123 and the second pressing portion 125 is connected to the first housing 110. In this embodiment, the first housing 110 includes a first bottom wall 111 and a first side wall 113 connected to the periphery of the first bottom wall 111. The first pressing portion 121, the stopper portion 123 and the second pressing portion 125 are respectively connected to the first bottom wall 111 of the first housing 110. The first pressing portion 121, the stopper portion 123 and the second pressing portion 125 are connected to form a U-shaped structure, which semi-encloses the block 160. In this way, the circuit board 210 extending from both sides of the block 160 can be pressed and fixed to prevent the circuit board 210 from deforming and warping, and the block 160 can be well limited to prevent the block 160 from deforming too much toward the outside of the housing 100.

[0044] Optionally, a connecting rib 115 is further provided between the stopper 123 and the first side wall 113 of the first housing 110 to improve the structural strength of the frame 120 and make the structure more reliable. The frame 120 and the first housing 110 can be integrally formed or connected separately, which is not specifically limited here.

[0045] Of course, in some embodiments, the perimeter frame 120 may also be in a "mouth"-shaped ring structure to fully surround the block 160, so that the contact area between the perimeter frame 120 and the circuit board 210 is larger, the circuit board 210 can be better pressed, and the structure is more reliable.

[0046] Combination Figures 4 to 7 Optionally, a groove 161 is provided on the block 160, and the groove 161 is used to install the circuit board 210. In this embodiment, the second housing 150 includes a second bottom wall 151 and a second side wall 153 connected to the circumference of the second bottom wall 151. The block 160 is provided on the second bottom wall 151 and extends in a direction perpendicular to the second bottom wall 151. Optionally, the block 160 is higher than the side of the second side wall 153 away from the second bottom wall 151. The groove 161 is provided at a position close to the top of the block 160, that is, the groove 161 is located at an end of the block 160 away from the second bottom wall 151. In this embodiment, there are two blocks 160, the two blocks 160 are arranged opposite to each other, and the notches of the grooves 161 on the two blocks 160 are opposite to each other, and the circuit board 210 is clamped between the two blocks 160.

[0047] It can be understood that when the circuit board 210 is installed, the first housing 110 and the second housing 150 are not connected at this time, and the circuit board 210 is assembled from top to bottom along the direction perpendicular to the second bottom wall 151. During the assembly process, the two blocks 160 will be squeezed to deform in the direction away from each other, so that the circuit board 210 can be smoothly inserted into the groove 161. After the circuit board 210 is inserted into the groove 161, the block 160 returns to its original state. Optionally, the depth of the groove 161 is L1, that is, after the circuit board 210 is installed, the amount of engagement of each block 160 with the circuit board 210 is L1. The gap between the block 160 and the stopper 123 is L2, and L1 is greater than L2. Since L2 is the assembly gap between the stopper 123 of the perimeter frame 120 and the block 160 after the first housing 110 and the second housing 150 are assembled. The assembly gap determines the maximum deformation amount of the block 160 toward the outside of the housing 100 after the housing 100 is assembled. When L1 is greater than L2, it can ensure that the block 160 always has a certain amount of engagement with the circuit board 210 to prevent the circuit board 210 from falling out. In this embodiment, L1 is about 1.5 mm and L2 is about 0.5 mm. Of course, the specific values ​​of L1 and L2 can be flexibly adjusted according to actual conditions and are not specifically limited here.

[0048] Optionally, one side of the clamping block 160 that clamps the circuit board 210 has a guide bevel 163 and a lift surface 165 connected to the guide bevel 163, and the lift surface 165 extends to the groove 161; in the direction perpendicular to the depth direction of the groove 161, that is, in the direction perpendicular to the second bottom wall 151, the height H of the lift surface 165 is greater than or equal to 0.5 mm. In this embodiment, the height of the lift surface 165 is about 0.8 mm. The provision of the lift surface 165 can prevent the lift surface 165 from being worn and collapsed after multiple assemblies of the circuit board 210, prevent the amount of engagement of the clamping block 160 with the circuit board 210 from being reduced, and improve the reliability of fixing the circuit board 210. Of course, the height H of the lift surface 165 can be flexibly adjusted according to actual conditions, and is not specifically limited here.

[0049] It can be understood that the setting of the guide bevel 163 facilitates the circuit board 210 to slide along the guide bevel 163 during installation and be smoothly installed in the groove 161. The guide bevel 163 guides the circuit board 210 during assembly, which is conducive to improving assembly efficiency and convenience. Optionally, the angle between the guide bevel 163 and the vertical plane can be 30 degrees to 75 degrees. In this embodiment, the angle between the guide bevel 163 and the vertical plane is about 60 degrees.

[0050] Optionally, a reinforcing rib 155 is provided between the block 160 and the second housing 150. Specifically, a reinforcing rib 155 is provided between a side of the block 160 away from the groove 161 and the second side wall 153 to improve the structural strength of the block 160 and better support and fix the circuit board 210.

[0051] Optionally, along the thickness direction of the wall of the second housing 150, the thickness of the block 160 is equal to the thickness of the wall of the second housing 150. It can be understood that the depth direction of the groove 161 is the thickness direction of the block 160, and the thickness of the block 160 is equal to the thickness of the second side wall 153, ensuring that the block 160 has sufficient structural strength.

[0052] Optionally, along the thickness direction of the wall of the second housing 150, that is, along the direction perpendicular to the second bottom wall 151, the distance D between the top of the block 160 and the top of the reinforcing rib 155 is greater than or equal to 8 mm. A certain space height is reserved between the top of the block 160 and the top of the reinforcing rib 155, which can provide sufficient deformation space for the block 160 during the assembly of the circuit board 210, so that the circuit board 210 can be smoothly inserted into the groove 161, thereby improving the convenience of operation and the assembly efficiency. In this embodiment, the distance D between the top of the block 160 and the top of the reinforcing rib 155 is about 10 mm.

[0053] The embodiment of the utility model further provides an electronic device 200, comprising a circuit board 210 and a housing 100 as in any of the above embodiments, wherein the circuit board 210 is mounted on a clamping block 160 of a second housing 150, and a surrounding frame 120 of a first housing 110 presses the circuit board 210, thereby improving the stability and reliability of the installation of the circuit board 210 and preventing the circuit board 210 from loosening or falling off. The electronic device 200 includes, but is not limited to, various electrical products such as electric meters, sockets, and lamps.

[0054] Combination Figure 2 Optionally, a positioning groove 211 is provided on the circuit board 210 at the position where the clamping block 160 is clamped, and the perimeter frame 120 is pressed on both sides of the positioning groove 211. By providing the positioning groove 211, it is convenient to position the circuit board 210 and to clamp the circuit board 210 and the clamping block 160. This design omits the structure of providing a positioning column on the housing 100 in the prior art, and the structure is simpler, material saving, and cost reduction.

[0055] The housing 100 and the electronic device provided in this embodiment have the following assembly and disassembly processes for the circuit board 210:

[0056] During assembly, the circuit board 210 is first slid from top to bottom along the guide slope 163 of the clamping block 160 into the groove 161, so that the circuit board 210 is clamped between the two clamping blocks 160. Then the first housing 110 and the second housing 150 are covered. After the first housing 110 is covered, the surrounding frame 120 on the first housing 110 surrounds the clamping block 160 and presses on the circuit board 210. In this way, the circuit board 210 is not easy to loosen or warp, the structure is reliable, and the assembly operation is fast and convenient.

[0057] During disassembly, the first housing 110 and the second housing 150 are disassembled first, and the clamping block 160 is deformed by external force, so that the circuit board 210 is taken out from the groove 161 of the clamping block 160 .

[0058] In summary, the housing 100 and the electronic device provided by the embodiment of the utility model have the following beneficial effects:

[0059] The housing 100 provided by the embodiment of the utility model has a perimeter frame 120 on the first housing 110, and a clamping block 160 on the second housing 150. The clamping block 160 is used to clamp and fix the circuit board 210. After the first housing 110 and the second housing 150 are assembled, the perimeter frame 120 is pressed on the circuit board 210, which can effectively prevent the circuit board 210 from warping and deforming, and prevent problems such as sparks and short circuits. At the same time, the perimeter frame 120 can also limit the clamping block 160, prevent the clamping block 160 from being separated from the circuit board 210 due to excessive deformation of the clamping block 160, improve the stability and reliability of the circuit board 210 during installation and transportation, and prevent the circuit board 210 from loosening and falling off.
