Description

Technical Field

[0001] The utility model relates to the technical field of analyzers, in particular to a flame-retardant insulating shell of an analyzer. Background Art

[0002] The housing and end caps of a CAN bus analyzer are generally made of stamped aluminum sheets. During the electrical isolation withstand voltage test, the plug-in solder joints at the bottom of the circuit board discharge into the metal housing or end cap tip, causing the air gap to be broken down, the insulation resistance to instantly drop to zero, and the isolation to fail. For the flame-retardant insulation on the outside, flame-retardant insulation baffles are generally installed inside the upper and lower sides of the housing. The metal USB interface on the PCB is in direct contact with the metal end cap. When the housing accidentally contacts another power source, a surge current will directly penetrate the USB cable into the computer and burn the motherboard. Therefore, the flame-retardant insulation of the end cap is also crucial. How to improve the flame-retardant insulation performance of the end cap and thus the flame-retardant insulation performance of the entire housing is an urgent problem to be solved.

[0003] In view of this, it is necessary to provide a new flame-retardant insulating shell of an analyzer to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the embodiments of the present invention hope to provide a flame-retardant insulating housing of an analyzer for improving the flame-retardant insulating performance of the end cover.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] A flame-retardant insulating shell of an analyzer includes a main shell, an end cover and a flame-retardant insulating partition. The flame-retardant insulating partition is installed between the end cover and the main shell. One side of the flame-retardant insulating partition is in contact with the end cover, and the other side is in contact with the side of the main shell and embedded in the end of the main shell. Fasteners pass through the end cover, the flame-retardant insulating partition and the main shell to fix the end cover and the flame-retardant insulating partition to the end of the main shell.

[0007] Preferably, the flame-retardant insulating partition is cut to form a limiting groove by fitting the outer peripheral edge of one end of the main shell, and the inner wall of the end of the main shell.

[0008] Preferably, the cross section of the limiting groove is L-shaped.

[0009] Preferably, the flame-retardant insulating partition is detachably connected to the main shell.

[0010] Preferably, the flame-retardant insulating partition is connected to the main shell through a snap connection.

[0011] Preferably, a hook is formed on one side of the flame-retardant insulating partition, and a slot is formed on the inner wall of the main shell, and the hook is inserted into the slot.

[0012] Preferably, a layer of insulating sealing gasket is attached to the side of the flame-retardant insulating partition that is in contact with the end cover.

[0013] Preferably, the insulating sealing pad is a rubber pad.

[0014] Preferably, the thickness of the flame retardant insulating partition is 1.5 to 2 mm.

[0015] Preferably, the flame retardant insulating partition is made of flame retardant plastic.

[0016] The flame-retardant insulating shell of the analyzer provided by the embodiment of the present invention forms a barrier between the main shell and the end cover by arranging the flame-retardant insulating partition between the main shell and the end cover, preventing direct contact between the PCB board in the main shell and the connector on the PCB board and the end cover, eliminating the occurrence of discharge, greatly improving the isolation level, thereby effectively increasing the service life of the product and reducing the maintenance rate.

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0021] Please refer to Figure 1-3The flame-retardant insulating shell of the analyzer includes a main shell 1, an end cover 2 and a flame-retardant insulating partition 3. The flame-retardant insulating partition 3 is installed between the end cover 2 and the main shell 1. One side of the flame-retardant insulating partition 3 is in contact with the end cover 2, and the other side is in contact with the side of the main shell 1 and embedded in the end of the main shell 1. The fastener 4 passes through the end cover 2, the flame-retardant insulating partition 3 and the main shell 1 from the end of the main shell 1 to fix the end cover 2 and the flame-retardant insulating partition 3 to the end of the main shell 1. By arranging the flame-retardant insulating partition 3 between the main shell 1 and the end cover 2, a barrier is formed between the main shell 1 and the end cover 2, preventing direct contact between the PCB board in the main shell 1 and the connector on the PCB board and the end cover 2, thereby eliminating the occurrence of discharge and greatly improving the isolation level, thereby effectively improving the service life of the product and reducing the maintenance rate.

[0022] Specifically, in this embodiment, the fastener 4 is a screw. Screw holes are provided on the end cover 2, the flame retardant insulating partition 3 and the main shell 1, and the screws pass through the end cover 2, the flame retardant insulating partition 3 and the main shell 1 to fix the end cover 2 and the flame retardant insulating partition 3 to the main shell 1. It should be noted that when end covers 2 are installed at both ends of the shell of the analyzer, a flame retardant insulating partition 3 is assembled between the end cover 2 and the main shell 1. In addition, insulating baffles are also installed on the upper and lower sides of the inner wall of the main shell 1 (parallel to the PCB board) to form a comprehensive flame retardant insulation method.

[0023] Furthermore, the flame-retardant insulating partition 3 is cut to form a limiting groove 31 by fitting the outer edge of one end of the main shell 1, and the inner wall of the end of the main shell 1 is also provided with a groove that is compatible with the structure of the limiting groove 31, so that the two can cooperate.

[0024] like Figure 2 and Figure 3 As shown, the cross section of the limiting groove 31 is L-shaped. At the same time, a 7-shaped groove is provided inside the end of the main shell 1. The two are adapted to allow the end cover 2 to be embedded in the main shell 1. In this way, the flame-retardant insulating partition 3 can form a good structural fit with the main shell 1, ensuring the sealing and compactness of the structure.

[0025] Furthermore, in order to enable the flame retardant insulating partition 3 to be quickly assembled and disassembled from the main shell 1, the flame retardant insulating partition 3 is detachably connected to the main shell 1, which can increase the installation speed and disassembly speed, thereby effectively improving work efficiency.

[0026] Preferably, the flame-retardant insulating partition 3 is connected to the main housing 1 via a snap-fit ​​connection. The snap-fit ​​connection effectively ensures that the flame-retardant insulating partition 3 is always connected and fixed to the main housing 1, and requires external force to disassemble, thereby ensuring connectivity and preventing the partition from separating from the main housing 1 due to problems such as loose end cap 2 or loose screws or stripping. The partition can always maintain its flame-retardant and insulating function, thus ensuring structural stability, further ensuring product stability, and reducing failure rates.

[0027] In detail, a hook 5 is formed on one side of the flame retardant insulating partition 3, and a slot 6 is formed on the inner wall of the main shell 1. The hook 5 is inserted into the slot 6 to ensure a good connection and fixation between the flame retardant insulating partition 3 and the main shell 1.

[0028] A layer of insulating sealing gasket 7 is attached to the side where the flame retardant insulating partition 3 and the end cover 2 are in contact to improve the sealing performance between the flame retardant insulating partition 3 and the end cover 2, and its thickness is between 0.2 and 0.4 mm. Preferably, the insulating sealing gasket 7 is a rubber gasket. The insulating sealing gasket 7 made of rubber has a certain compressibility and resilience, which can play a good sealing role and effectively improve the waterproof and dustproof performance between the end cover 2 and the flame retardant insulating partition 3. In addition, it is worth mentioning that in order to improve the sealing between the partition and the main shell, a layer of rubber gasket can also be attached to the other side of the flame retardant insulating partition.

[0029] Furthermore, the thickness of the flame-retardant insulating partition 3 is 1.5 to 2 mm. Specifically, in this embodiment, the thickness of the flame-retardant insulating partition 3 is 1.5 mm. The flame-retardant insulating partition 3 must have a certain thickness to provide flame retardancy and insulation, and to prevent electric sparks from penetrating the partition if it is too thin.

[0030] Preferably, the flame-retardant insulating partition 3 is made of a flame-retardant material, specifically a flame-retardant plastic, such as polyphosphate plastic, polyphenylene sulfide plastic, or flame-retardant nylon plastic. As will be appreciated, since plastic has a certain degree of deformability, the snap-fit ​​connection between the partition and the main housing 1 facilitates assembly and disassembly.

[0031] The flame-retardant insulating shell of the analyzer provided by the embodiment of the present invention forms a barrier between the main shell 1 and the end cover 2 by arranging the flame-retardant insulating partition 3 between the main shell 1 and the end cover 2, thereby preventing contact between the PCB board in the main shell 1 and the connector on the PCB board and the end cover 2, eliminating the occurrence of discharge, greatly improving the isolation level, thereby effectively increasing the service life of the product and reducing the maintenance rate.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
