Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present application. The first and second elements are both elements, but they are not the same element.

In this embodiment, as shown in fig. 1 to 5, the present invention includes: impact transmitter includes 1 and 1 internally mounted of shell has impact transmitter body 2, its characterized in that includes: the shell 1 comprises a transmitter shell 3 and a gauge head shell 4, the gauge head shell 4 is connected with the transmitter shell 3, the gauge head shell 7 comprises a first electrical interface 5, a second electrical interface 6 and an upper end cover 42, a circuit board 31 installed in the transmitter shell 3 is connected with a wiring terminal 41 in the gauge head shell 4, the first electrical interface 5 and the second electrical interface 6 are oppositely arranged on two sides of the gauge head shell 4, and the first electrical interface 5 and the second electrical interface 6 and the upper end cover 42 are connected into a whole. Based on above-mentioned design, technical scheme solve following technical problem: when overhauing the installation, because the radius of gyration of motor wiring mouth department is great among the prior art, occupation space is big, and the casing volume is also great moreover, and the user is when using, and motor wiring mouth is sheltered from by other devices, and wiring mouth space is narrow to lead to the installation difficulty.

Wherein, the transmitter housing 3 and the gauge head housing 4 are sealed by a sealing element 7. The sealing element 7 may be an O-ring, e.g. a circular rubber sealing ring. The device utilizes the sealing element 7 with higher sealing performance, so that the device can be used in industrial places with large dust and extremely harsh environment.
