Abstract

The present invention relates to a connecting apparatus including a fixed terminal part having a hollow portion and fixed in a predetermined space between a first substrate, on which electrical components are mounted, and a second substrate disposed in parallel with the first substrate, one terminal part fixed to one end of the fixed terminal part and configured to be elastically supported on the first substrate, one terminal part being configured to slip and come into contact with an inner surface of the first substrate, and the other terminal part fixed to the other end of the fixed terminal part and configured to be elastically supported on the second substrate, the other terminal part being configured to slip and come into contact with an inner surface of the second substrate, in which one terminal part and the other terminal part are elastically supported by an elastic member installed in the hollow portion of the fixed terminal part and configured to be extended or contracted, thereby providing an advantage of easily absorbing assembling tolerance existing between two substrates and provides a very simple assembling process.

First claim

2 . The connecting apparatus of claim 1 , wherein one terminal part and the other terminal part are coupled to overlap ends of the fixed terminal part by predetermined distances in a longitudinal direction.

3 . The connecting apparatus of claim 1 , wherein one terminal part and the other terminal part each have a plurality of cut-out portions formed by cutting a part of an outer peripheral surface of a portion of each of one terminal part and the other terminal part, which is coupled to the fixed terminal part, in a longitudinal direction, and the plurality of cut-out portions is spaced apart from one another in a circumferential direction.

4 . The connecting apparatus of claim 1 , wherein a contact point end of one terminal part, which is configured to come into contact with the first substrate, and a contact point end of the other terminal part, which is configured to come into contact with the second substrate, each include a plurality of protrusion portions protruding to implement at least two point contact points.

5 . The connecting apparatus of claim 1 , wherein a contact point end of one terminal part, which is configured to come into contact with the first substrate, and a contact point end of the other terminal part, which is configured to come into contact with the second substrate, each include a contact point groove formed to be recessed, and a contact point flat surface formed to be flat at the periphery of the contact point groove.

6 . A connecting apparatus comprising:
a fixed terminal part having a hollow portion and fixed in a predetermined space between a first substrate, on which electrical components are mounted, and a second substrate disposed in parallel with the first substrate; one terminal part fixed to one end of the fixed terminal part and configured to be elastically supported on the first substrate, one terminal part being configured to slip and come into contact with an inner surface of the first substrate; and the other terminal part fixed to the other end of the fixed terminal part and configured to be elastically supported on the second substrate, the other terminal part being configured to slip and come into contact with an inner surface of the second substrate, wherein one terminal part and the other terminal part are elastically supported by an elastic member installed in the hollow portion of the fixed terminal part and configured to be extended or compressed, wherein one terminal part and the other terminal part respectively have hollow portions into which ends of the elastic member are inserted and supported, and one terminal part and the other terminal part are inserted into the hollow portion of the fixed terminal part while overlapping the fixed terminal part and respectively hook-engage with inner sides of inlet ends of the hollow portion of the fixed terminal part.

7 . The connecting apparatus of claim 6 , wherein the elastic member is provided as an integrated spring having one end inserted and supported in the hollow portion of one terminal part, and the other end inserted and supported in the hollow portion of the other terminal part.

8 . A connecting apparatus comprising:
a cavity filter having one side fixed to a resonant element and having a terminal pin fixed in an impedance matching space provided to match impedance in a radial direction; and an RF connector configured to absorb assembling tolerance between the terminal pin and a relevant PCB and fixed in the impedance matching space between the terminal pin and the relevant PCB disposed in parallel with and spaced apart, by a predetermined distance, from the resonant element, wherein the RF connector comprises: a fixed terminal part having a hollow portion; one terminal part fixed to one end of the fixed terminal part and configured to be elastically supported on the terminal pin, one terminal part being configured to slip and come into contact with a contact surface of the terminal pin; and the other terminal part fixed to the other end of the fixed terminal part and configured to be elastically supported on the relevant PCB, the other terminal part being configured to slip and come into contact with a contact surface of the relevant PCB, and wherein one terminal part and the other terminal part are elastically supported by an elastic member installed in the hollow portion of the fixed terminal part and configured to be extended or compressed.

9 . The connecting apparatus of claim 8 , wherein an outer surface area of the other end of the terminal pin is larger than an outer surface area of one end of one terminal part of the RF connector.

10 . The connecting apparatus of claim 8 , wherein the impedance matching space of the cavity filter is fitted with the terminal pin to cover a part of an outer peripheral surface of the terminal pin, or a terminal pin side dielectric material is inserted into the impedance matching space so as to be disposed in a radial direction of the outer peripheral surface of the terminal pin, such that impedance matching is designed.
