Abstract
Description
Technical field
[0001] The utility model relates to a CAN bus cable signal quality detection device. [Background Technology]
[0002] The CAN bus is a multi-master serial communication bus. Its basic design specifications require high bit rates, strong resistance to electronic interference, and the ability to detect any errors. The CAN bus is applicable in automotive electrical control systems, elevator control systems, safety monitoring systems, medical equipment, textile machinery, and marine applications. When using a detection device to test CAN bus cable signals, the signal quality is measured by connecting the test needle on the device to the port of the cable under test. These test needles are typically wrapped around the device using signal cables, leaving the test needles exposed. During daily transportation and storage, the test needles can easily poke other objects, while the signal cable sheath is susceptible to wear and tear and puncture.
[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]
[0004] The purpose of the present invention is to overcome the above problems. We provide a CAN bus cable signal quality detection device, which has a storage cavity for storing CAN detection needles.

[0006] In one or more embodiments, a partition is provided in the middle of the storage cavity, and the partition is used to separate the first CAN detection needle from the second CAN detection needle.
[0007] In one or more embodiments, slide grooves are provided on both sides of the storage cavity, both sides of the cover plate are slidably connected to the slide grooves on both sides of the storage cavity, a buckle is provided on the cover plate, and a buckle position cooperating with the buckle is provided on the storage cavity.
[0008] In one or more embodiments, a handle recess is provided on the front surface of the cover plate, and an anti-slip structure is provided on the handle recess.
