Embodiment Construction

[0021] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the application are given in the drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0022] In this example, if figure 1 , figure 2 , image 3 shown. A sound-absorbing harness plugging cover, characterized in that it includes a fixed layer 1 and a sound-absorbing layer 2, the sound-absorbing layer 2 is fixed on the back of the fixed layer 1, the shape of the sound-absorbing layer 2 is the same as that of the fixed layer 1, and the aspect ratio of the sound-absorbing layer 2 is The length and width of the fixed layer 1 are small; the center of the fixed layer 1...

Abstract

The sound-absorbing wire harness blanking cap comprises a fixing layer and a sound-absorbing layer, the sound-absorbing layer is fixed to the back of the fixing layer, the shape of the sound-absorbing layer is the same as that of the fixing layer, and the length and width of the sound-absorbing layer are smaller than those of the fixing layer; a flaring-shaped front line hole is formed in the center of the fixing layer, and a rear line hole is formed in the corresponding position of the sound absorption layer; the side edge of the fixing layer is provided with a front notch directly communicated with the front wire hole, and the corresponding position of the sound absorbing layer is directly communicated with a rear notch of the rear wire hole; an annular groove is formed in the periphery of the fixing layer, and an annular boss used for stopping is arranged behind the groove. And the fixing layer is made of a foaming PE (Poly Ethylene) material. According to the wire harness blanking cap, sealing after the wire harness passes through the center hole can be avoided, the wire harness blanking cap does not need to be integrated to the wire harness in advance, the wire harness structure is simplified, and the installation cost and use are reduced. And sound and air flow in the outer cavity can be effectively isolated. And the fixing device is suitable for fixing single-layer and double-layer metal plates. The foaming PE material is small in density, light in weight and free of peculiar smell.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a sound-absorbing wiring harness plugging cover. Background technique [0002] At present, the pure electric axle vehicles or SUV models that have been launched in China generally have large wiring harness holes. Generally, the rubber or plastic plugging caps that come with the wiring harness are used to seal the via holes. This type of plug needs to be integrated and wound on the wire harness for supply, and generally does not have the function of sound absorption. If the wire harness or the plug is damaged, a complete set must be replaced, which is not economical to use. Existing blocking cover generally can only be applicable to thinner but sheet metal parts are fixed, and the rubber weight that uses is bigger, and rubber smell is also heavy. Contents of the invention [0003] Based on the above statement, the present invention provides a sound-absorbing wire harness co...
