Problems solved by technology

However, in in-vehicle equipment, if the cable is too long, it may resonate and apply stress to the soldered part, or cause abnormal noise due to contact with other components.
It is difficult to solve the difference between the case where the coaxial cable is short and the case where the coaxial cable is long with the conventional structure

Embodiment Construction

[0037] Hereinafter, the antenna of the present invention will be described in detail by taking the vehicle-mounted antenna 1 as an example based on the drawings.

[0038] The vehicle-mounted antenna 1 of the present embodiment is, for example, figure 1 as well as figure 2 As shown, an antenna body 10 and an antenna bracket 20 are provided. In the vehicle-mounted antenna 1, the antenna body 10 is held by the antenna holder 20, and the coaxial cable 40 welded to the antenna body 10 is held by the antenna holder 20, so that even if the coaxial cable 40 is stretched, the welded part is secured. Integrity. In addition, in the vehicle-mounted antenna 1, set figure 1 The side shown is the front side, place the figure 2 The side shown is defined as the inner side.

[0039] Hereinafter, the configuration of the on-vehicle antenna 1 will be described, and then the functions and effects achieved by the on-vehicle antenna 1 will be described.

Abstract

The invention provides an antenna at low cost, wherein the antenna can maintain the integrity of a welding part even if an electrical cable is tensioned. The vehicle-mounted antenna (1) is provided with an antenna body (10) which is formed by the sheet-metal working of a metal plate and provided with an oscillator part (11) and a grounding part (20) in integrated connection with the oscillator part (11). The oscillator part (11) is provided with a first welding part (15) and a second welding part (16) which are used for the welding of coaxial cables (40). The vehicle-mounted antenna (1) is also provided with a resin antenna support (20) which holds the antenna body (10). The antenna support (20) is provided with an antenna holding part (21) which holds the antenna body (10); and a cable holding part (25) which inhibits the transmission of tension forces and vibration generated on the coaxial cables (40) to the welding parts, and holds the coaxial cables (40).

Description

technical field [0001] The present invention relates to an antenna suitable for wireless communication with in-vehicle equipment. Background technique [0002] An in-vehicle antenna is incorporated as an element of a vehicle electronic device, for example, a Bluetooth (registered trademark) module of a navigation device. In order to reduce the cost of such an antenna, an antenna produced by sheet metal processing of a metal plate is often used (for example, Patent Document 1). [0003] The metal sheet antenna is connected to a coaxial cable for signal transmission and reception with the electronic device, but when the metal sheet antenna is attached to the housing of the electronic device, or when the connector is fitted, there is a coaxial cable. The cable is stretched. Then, at the soldered portion connecting the coaxial cable and the metal sheet antenna, the solder falls off, or the coaxial cable is disconnected at the soldered portion, and the integrity of the soldered...
