Description

Fastener for fixing coaxial line plug-in

Technical Field

The utility model relates to an automobile electrical system, in particular to a buckle for fixing a coaxial line plug-in unit.

Background

With the expansion of the application of coaxial line technology in automobile communication, a plurality of electrical systems with higher requirements on signal transmission are converted to be suitable for coaxial line transmission, the coaxial line plug-ins meeting the international standard USCAR-17 are adopted in the high-definition 360 panoramic system, the face recognition system and other systems at present, and the coaxial line plug-ins on the vehicle are obviously increased by converting the traditional antenna feeder line and the interface of the GPS antenna to the coaxial line plug-ins meeting the international standard USCAR-17.

As shown in fig. 1 to 3, an oblong hole 9 is formed in the mounting bracket 8, and the coaxial line plug-in unit 5 is fixed on the mounting bracket 8 through a common buckle 7 which can be clamped into the oblong hole 9. When the vehicle needs to pass through two coaxial line inserts, two common buckles are needed to be fixed at two different places of the mounting bracket respectively. The original long round hole on the mounting bracket is not enough to be used, and a long round hole needs to be added on the mounting bracket, so that the mounting bracket needs to be designed and changed or redeveloped, and factors such as incapability of adding the long round hole due to other structures possibly exist below the position of the newly added long round hole on the mounting bracket. In the case of a vehicle model which is already mass-produced, when the above-mentioned configuration changes are added in the course of minor improvement and development, the requirements for the peripheral space are difficult to satisfy, and peripheral parts are required to be changed in a matching manner. In this case, if according to the traditional design concept, a mounting hole needs to be newly added on a nearby metal plate or a bracket to fix a newly added coaxial plug-in, but the situation that enough space is not reserved in early design or the situation that the cost for changing the matched parts is high often exists.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a novel coaxial line plug-in fastener for an automobile, which can be used for mounting two coaxial line plugs at the same position and reducing the space size occupied by the two coaxial line plugs. The change of peripheral parts can be avoided, and the change cost and the change period are reduced.

The technical scheme of the utility model is that the buckle for fixing the coaxial line plug-in unit comprises a T-shaped clamping main body and a flange plate, wherein the flange plate fixes a clamping main body on an installation support; the plane is provided with the mounting groove of two coaxial line plug-ins on the T type of joint main part. When the ring flange on the buckle is used for the buckle to fix on the panel beating of different thickness, compress tightly the buckle on the panel beating to play the fastening buckle, prevent abnormal sound or the effect that drops.

Specifically, a pair of wedge-shaped structures is further arranged at the clamping position where the clamping main body is matched with the mounting bracket.

Furthermore, a pair of wedge structures is axially and symmetrically arranged along the clamping position.

Wherein, the wedge structure is equipped with three-layer step to the panel beating that is applicable to different thickness is fixed.

Specifically, the mounting groove structure is in a shape like a Chinese character 'tu', and slides into a concave groove on the matched coaxial line plug-in during mounting.

The utility model has the beneficial effects that: when the vehicle configuration is increased or the scheme is changed, when two coaxial line plug-ins need to pass through the same position, according to the traditional thought, a mounting hole needs to be newly added on a nearby metal plate or a bracket for fixing the newly added coaxial line plug-ins, but the situations that the peripheral space is small or the change period of the matched parts is short or the cost is high often exist. After using this novel buckle, can not change under the circumstances of peripheral panel beating or support, use a mounting hole that exists originally, through two coaxial line plug-ins of this novel coaxial line buckle fixed, can reduce the change of peripheral cooperation panel beating or support, save cycle and cost. And after the coaxial line plug-in components are fixed together by the coaxial line plug-in component buckle, the space requirement can be reduced due to the fact that the distance between the two buckles fixed in the traditional mode is reduced. In conclusion, the utility model has the advantages of simple structure, convenient installation, small occupied space, capability of reducing development period and cost, reduction of the matching change of peripheral parts and the like.

Detailed Description

Example 1

Referring to fig. 4-6, the buckle comprises a T-shaped clamping main body 1 and a flange plate 2, and the flange plate 2 fixes the clamping main body 1 on a mounting bracket 8; the plane is provided with mounting groove 3 of two coaxial line plug-ins 5 on the T type of joint main part 1. When the ring flange on the buckle is used for the buckle to fix on the panel beating of different thickness, compress tightly the buckle on the panel beating to play the fastening buckle, prevent abnormal sound or the effect that drops. In order to facilitate the matching of the buckle and the mounting bracket, a pair of wedge-shaped structures 4 is further arranged at the clamping position where the clamping main body 1 is matched with the mounting bracket 8.

In a preferred embodiment, a pair of said wedge structures 4 is arranged axially symmetrically along the clamping portion. Wherein, wedge structure 4 is equipped with three-layer step to the panel beating that is applicable to different thickness is fixed.

As another preferred embodiment, the mounting groove 3 is in a shape like a Chinese character 'tu', and is arranged to slide into the concave groove 6 of the coaxial line insert 5, so as to realize the fastening installation of the two.

Referring to fig. 7, when the vehicle needs to pass through two coaxial line inserts 5, only two coaxial line inserts 5 need to be clamped with two mounting grooves 3 on the clamping body 1 through the concave groove 6 at the same time. The clamping body 1 is clamped in the long round hole 9 of the mounting bracket 8 through the wedge-shaped structure 4. Compared with the condition of installing a coaxial line plug-in unit, the installation support does not need to be changed, the original long round hole is still used, and the two coaxial line plug-in units can be fixed through a buckle. The change period and cost of the mounting bracket can be reduced, and the requirement on space is smaller.
