Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to a multi-channel antenna code table. Background Art

[0002] A stopwatch is an electronic product installed on bicycles, motorcycles, cars, etc. to record and display certain riding data, such as current speed, riding mileage, riding time, etc. High-end stopwatches also have altitude, air pressure, slope display, etc.

[0003] At present, the computer is equipped with antennas and circuit boards, with exposed copper contacts on the circuit boards. The antenna is made of elastic steel sheets, so the antenna is connected to the exposed copper contacts through its own elastic force. However, due to the poor consistency of the antenna elastic force, when there are many antennas, not all antennas can be in a conductive state. Utility Model Content

[0004] Based on the above description, the utility model provides a multi-antenna code table, aiming to solve the problem that the antennas of the existing code table cannot all be in a conducting state.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A multi-channel antenna code table, comprising:

[0007] case;

[0008] A circuit board, the circuit board is arranged in the housing, the circuit board has a first assembly area and at least two second assembly areas, and the first assembly area and each of the second assembly areas are provided with a spring sheet;

[0009] Metal contacts, the metal contacts are arranged on the springs in a one-to-one correspondence;

[0010] A first antenna and at least two second antennas, wherein the first antenna and each second antenna are arranged between the shell and the circuit board, the first antenna corresponds to the first assembly area, the second antenna corresponds to the second assembly area one by one, and the first antenna and each second antenna are in contact with the metal contact.

[0016] Furthermore, the spring sheet includes two side stops, each of which is disposed on the base portion, and the two side stops are separated to form a clearance space.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] (1) The present application uses a standardized spring sheet design and arranges a metal contact on the spring sheet. The elastic force of the spring sheet can achieve contact and conduction between the first antenna and the second antenna and the metal contact, while ensuring the contact accuracy between the first antenna and the second antenna and the metal contact.

[0019] (2) The present application uses the positioning protrusion and the positioning hole to coordinate, firstly, enable the second antenna to find the assembly position more quickly, so as to facilitate the installation of the second antenna; secondly, prevent the second antenna from moving at will, so that the second antenna can always maintain a conductive state with the metal contact.

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0031] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0032] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0034] For example, the first antenna 50 may be an LDS antenna, etc. The spring sheet 30 may be attached to the circuit board 20. The number of spring sheets 30 is configured according to the number of contacts of the first antenna 50 and the second antenna 60, and is not further limited here.

[0035] According to this embodiment, the spring clip 30 is designed in a standardized manner, and the metal contact 40 is arranged on the spring clip 30. Through the elastic force of the spring clip 30, the contact accuracy between the first antenna 50 and the second antenna 60 and the metal contact 40 can be achieved, and it can also ensure that all the first antennas 50 and the second antennas 60 are in contact and conductive with the metal contacts 40.

[0037] According to this embodiment, through the cooperation between the positioning protrusion 11 and the positioning hole 61, firstly, the second antenna 60 can find the assembly position more quickly to facilitate the installation of the second antenna 60; secondly, the second antenna 60 will not move randomly, so that the second antenna 60 can always maintain a conductive state with the metal contact 40.

[0038] In some embodiments, the metal contact 40 and the spring 30 are integrally formed.

[0039] According to this embodiment, standardized production can be achieved in this way, so that the heights of the metal contacts 40 remain consistent, thereby ensuring that all antennas can be turned on.
