Summary of the Invention

Problems to be Solved by the Invention

[0004] In the input / output section of a high-frequency signal, depending on the functions of the electronic device, a plurality of electrical components may be connected in a predetermined order. In a configuration where a plurality of electrical components are connected in this way, in the conventional art, when electrical components arranged in a certain arrangement order do not satisfy the reference value of a predetermined electrical characteristic, it is difficult to take measures such as changing the arrangement order of the electrical components or replacing them with other components so as to satisfy the reference value.

[0005] Therefore, the present invention has been made in view of these points, and an object thereof is to provide a component mounting structure that can be easily adjusted so as to satisfy the reference value of a predetermined electrical characteristic in a configuration where a plurality of electrical components are connected to each other.

A second through-hole through which the second fixture passes is formed in the support portion as an elongated hole extending in the same direction as the first through-hole, and the central axis in the longitudinal direction of the second through-hole and the central axis in the longitudinal direction of the first through-hole may be the same.

[0008] The first through-hole is formed to have a length such that the first electrical component is fixed to the support portion by the first fixture in a state where the coaxial connector of the first length is directly connected to the first electrical component or indirectly connected to the first electrical component via the second electrical component, and in a state where the coaxial connector of the second length is directly connected to the first electrical component or indirectly connected to the first electrical component via the second electrical component, the first electrical component is fixed to the support portion by the first fixture.

Embodiment for Carrying Out the Invention

[0013] FIG. 1 is a perspective view showing a component mounting structure according to an embodiment of the present invention. FIG. 2 is a plan view of the component mounting structure as viewed from above. FIG. 3 is a plan view of the mounting bracket. FIG. 4 is a cross-sectional view showing a state in which an isolator is fixed to the mounting bracket. FIG. 5 is a view showing the component mounting structure when the connection state of the electrical component is changed.

[0014] The component mounting structure S100 of the present embodiment is a structure for mounting a plurality of electrical components that transmit electrical signals to the housing of an electronic device. Specifically, the component mounting structure S100 includes an isolator 21, a coaxial attenuator 22, a coaxial connector 23, a fixed connector 24, a fixing screw 25 (FIG. 4), and a mounting bracket 10. The component mounting structure S100 is, for example, an interface for high-frequency signals of a satellite earth station panel.

[0015] The isolator 21, the coaxial attenuator 22, the coaxial connector 23, and the fixed connector 24 are arranged in series in a straight line along the line L1. Although each electronic component can be rearranged as appropriate as described later, in the examples of FIGS. 1 and 2, the isolator 21, the coaxial attenuator 22, the coaxial connector 23, and the fixed connector 24 are coaxially connected in this order.

[0016] The isolator 21 is an electrical component that allows an electrical signal traveling in the forward direction to pass through and attenuates a signal in the reverse direction with a large attenuation amount. The isolator 21 corresponds to the first electrical component of the present invention. The isolator 21 has a screw hole into which the tip of the fixing screw 25 is screwed in a part of its housing, and as shown in FIG. 4, is attached to the mounting bracket 10 by the fixing screw 25.

[0017] The coaxial attenuator 22 is an electronic component that attenuates an electrical signal and corresponds to the second electrical component of the present invention. The coaxial attenuator 22 does not necessarily have to be configured to be attached to the mounting bracket 10 by a fixing screw, but depending on the shape of the product of the coaxial attenuator 22, the coaxial attenuator 22 may also be attached to the mounting bracket 10 by a fixing screw.

[0018] The coaxial connector 23 is an electrical component for connecting predetermined components to each other. In FIG. 2, the coaxial connector 23 connects the coaxial attenuator 22 and the fixed connector 24. In the present embodiment, as shown in FIG. 5, either the coaxial connector 23A having a first length or the coaxial connector 23B having a second length different from the first length is fixed to the mounting bracket 10. The coaxial connector 23A is, for example, a connector having a relatively long axial length of the connector, and the coaxial connector 23B is a relatively short connector.

[0019] The fixed connector 24 is a connector for fixing the electrical components in a connected state to each other to the housing 50 of the electronic device. In FIG. 2, one end of the fixed connector 24 is connected to the coaxial connector 23, and the other end of the fixed connector 24 is fixed to the housing 50. The housing 50 is, for example, the back surface of the electronic device.

[0020] The fixing screw 25 is a fixture for fixing the isolator 21 to the support portion 10-1 of the mounting bracket 10. The component mounting structure S100 may have, for example, another fixing screw (second fixing screw) for fixing the isolator 21 or other electrical components to a position corresponding to the second through hole 10b.

[0021] The mounting bracket 10 is a member for mounting the isolator 21, the coaxial attenuator 22, the coaxial connector 23, and the fixed connector 24 to the housing 50 of the electronic device. As shown in FIG. 4, the mounting bracket 10 has a support portion 10-1 and a housing mounting portion 10-2. In this example, the mounting bracket 10 is an L-shaped member in which the support portion 10-1 and the housing mounting portion 10-2 are integrally formed.

[0022] The support portion 10-1 is, for example, plate-shaped and has a flat upper surface on which the isolator 21, the coaxial attenuator 22, the coaxial connector 23, and the fixed connector 24 (only the isolator 21 is shown in FIG. 4) are arranged.

[0023] In the support part 10-1, a first through hole 10a and a second through hole 10b are formed. The first through hole 10a is a hole through which a fixing screw 25, which is a first fixture, passes, and the second through hole 10b is a hole through which a fixing screw (not shown), which is a second fixture, passes.

[0024] The first through hole 10a is an elongated hole extending in a direction along a line L1, which is the arrangement direction of a plurality of electrical components. The first through hole 10a has a certain width dimension as an example.

[0025] During the manufacture of the components, these electrical components are fixed to the mounting bracket 10, and a test is performed to determine whether the components satisfy a predetermined communication characteristic (for example, the characteristic of VSWR: Voltage Standing Wave Ratio) in a state where the plurality of electrical components are connected to each other. Here, due to variations in the performance of each electrical component, etc., there may be cases where the reference value is not satisfied in a predetermined arrangement order. And in such cases, by changing the arrangement order of the electrical components or changing the length of the coaxial connector 23, the reference value may come to be satisfied.

[0026] In the present embodiment, in view of such a point, the first through hole 10a is formed as an elongated hole so that the electrical components can be satisfactorily fixed to the mounting bracket 10 even when the arrangement order of the electrical components is changed or the length of the coaxial connector 23 is changed. Thereby, for example, even when changing from the long coaxial connector 23A shown in FIG. 5(a) to the short coaxial connector 23B shown in FIG. 5(b), the isolator 21 can be satisfactorily fixed to the mounting bracket 10 by the fixing screw 25 passed through the first through hole 10a (FIG. 4), and the trouble of fixing the isolator 21 again using other fixtures becomes unnecessary.

[0027] The second through hole 10b is also formed as an elongated hole in the same manner as the first through hole 10a. The second through hole 10b is provided, as an example, at a position such that the central axis in the longitudinal direction of the second through hole 10b and the central axis in the longitudinal direction of the first through hole 10a are the same.

[0028] Since the first through hole 10a is an elongated hole, there is an advantage that the position of the isolator 21 can be adjusted. However, the length of the first through hole 10a may be specifically set as follows. That is, the first through hole 10a is in a state where the coaxial connector 23A of the first length is directly connected to the isolator 21 which is the first electrical component, or is indirectly connected to the isolator 21 via the coaxial attenuator 22 which is the second electrical component, and the isolator 21 is fixed by the fixing screw 25, and the coaxial connector 23B of the second length is directly connected to the isolator 21, or is indirectly connected to the isolator 21 via the coaxial attenuator 22, and it is preferably formed to have a length such that the isolator 21 can be fixed by the fixing screw 25.

[0029] In the component mounting structure S100, the arrangement order of the electrical components may be changed. Specifically, it is assumed as an example that the isolator 21 is arranged at a position corresponding to the second through hole 10b. Therefore, the first through hole 10a and the second through hole 10b are in a state where the isolator 21 and the coaxial attenuator 22 are respectively arranged at positions corresponding to the first through hole 10a and the second through hole 10b, and the isolator 21 is fixed by the fixing screw 25 passed through the first through hole 10a, and when the positions of the isolator 21 and the coaxial attenuator 22 are swapped, it may be formed to have a length such that the isolator 21 is fixed by the fixing screw passed through the second through hole 10b.

[0030] In the above, it is exemplified that the isolator 21 is fixed by the fixing screw, but the present invention is not limited to this, and any first electrical component and / or any second electrical component may be fixed to the mounting bracket 10 by a fixture such as a fixing screw.

[0031] The housing mounting portion 10-2 is a plate-like portion extending so as to bend from the support portion 10-1. The housing mounting portion 10-2 is bent at a right angle with respect to the support portion 10-1, for example. The connection portion between the support portion 10-1 and the housing mounting portion 10-2 is formed in a gently curved arc shape as shown in FIG. 4.

[0032] FIG. 6 is a diagram illustrating an arrangement pattern of electrical components. According to the configuration of the present embodiment, a plurality of electrical components can be arranged in the patterns shown in (1) to (6) of FIG. 6. The coaxial ATT corresponds to the coaxial attenuator 22, the connector A corresponds to the fixed connector 24, and the connector B corresponds to the coaxial connector 23.

[0033] (Effect) As described above, according to the configuration of the present embodiment, since the first through hole 10a is provided as a long hole, it becomes easy to perform adjustment so as to satisfy the reference value of predetermined electrical characteristics in a configuration in which a plurality of electrical components are connected to each other.

[0034] As described above, the present invention has been described using embodiments. However, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist. For example, all or part of the device can be configured to be functionally or physically dispersed and integrated in an arbitrary unit. Further, new embodiments generated by an arbitrary combination of a plurality of embodiments are also included in the embodiments of the present invention. The effects of the new embodiments generated by the combination have the effects of the original embodiments combined.
