The present invention relates to a coaxial cable adapter, in particular to an in-line convex flange protruding inward in a middle portion of a guide piece, so that the tubular conductor can tightly and elastically clamp the coaxial cable core inserted in the receiving groove. For high frequency signal transmission.

Coaxial cable is a signal transmission line widely used in TV and network systems for carrying and transmitting high-frequency signals, and is locked to audio-visual or network equipment by a coaxial cable connector disposed at the end. Coaxial cable connector. Taking a common F-type coaxial cable joint as an example, the sleeve is connected with a coaxial cable, and the front end of the sleeve is provided with a rotatable annular nut, and the inner surface of the annular nut is provided with a female thread.

Generally, the adapter used in the F-type coaxial cable connector includes an electrically conductive male thread disposed at both ends of the body and an axial direction. a conductive terminal disposed in the body and an insulating bushing disposed between the conductive terminal and the conductive male male thread. Each of the two ends of the conductive terminal has a clamping end, and the clamping end has a plurality of elastic pieces separated by a slit, and the clamping end is formed by the opening to gradually reduce the inner diameter thereof in the axial direction. When the different coaxial cables are respectively coupled to the two ends of the adapter, the coaxial cable cores are respectively clamped by the elastic pieces of the clamping end, and the coaxial cables at both ends of the adapter are electrically connected.

In the above-mentioned adapter, it is not only used as a coupling component for combining different coaxial cables, but also as a transmission component for electronic transmission between dissimilar coaxial cables. Therefore, the combination of instability has a negative impact on the transmission of signals. . The combination of the conductive terminal and the coaxial cable core utilizes a plurality of elastic pieces to cooperatively clamp the core wire therebetween, so that after a plurality of core wire insertion and removal operations over a period of time, especially after the insertion and removal of different diameter core wires, the spring piece is easily generated. Elastic fatigue In the case where the core wire cannot be tightly held, the electrical connection is poor, resulting in loss of high frequency output efficiency.

In view of this, in order to allow the coaxial cable adapter to be inserted and removed after multiple times of the coaxial cable core wire, a stable bonding state can be obtained between the core wires combined with each other to maintain good electrical contact, and the creator has accumulated many years of experience. And continuous research and development improvements, the creation of this creation.

The main purpose of the present invention is to provide a coaxial cable adapter, which is formed by projecting an arched flange on a middle portion of each of the guide segments of the tubular conductor, and inserting the coaxial cable into the receiving groove of the tubular conductor. Inwardly, the coaxial cable core is elastically held by an arched flange on a plurality of guides at each end of the tubular conductor.

For the above purposes, the coaxial cable adapter of the present invention comprises a body, a tubular conductor disposed in the body, and an insulating bushing disposed between the body and the tubular conductor, the two ends of the tubular conductor Each of the guide sheets at each end forms a receiving groove for inserting the coaxial cable core wire, and the middle portion of the guide piece is recessed toward the receiving groove, and each of the guiding pieces is recessed toward the receiving groove. The middle portion of the guide piece is convexly formed with an arched flange in the accommodating groove, so that the tubular conductor can tightly and elastically clamp the coaxial cable core inserted in the accommodating groove by the arched flange of the guide piece.

The creation system can stably integrate the core wire of the coaxial cable into the tubular conductor after the coaxial cable is combined to maintain good electrical contact, thereby obtaining better high-frequency transmission efficiency.

In order to further understand the present invention, the preferred embodiments of the present invention, together with the drawings and figure numbers, detail the specific components of the present creation and the effects achieved thereby.

Fig. 3A is a schematic cross-sectional view of the tubular conductor taken along the line a-a' in the embodiment of Fig. 3.

Please refer to FIG. 1-2, which is an embodiment of the inventive coaxial cable connector, comprising a body 1, a tubular conductor 2 axially disposed in the body 1, and two insulating bushings 3.

The body 1 is made of a conductive material, and has an axial passage 10 formed therein, and an outer circumferential surface of the body 1 is provided with a male thread 11 at a position adjacent to the opposite ends of the coaxial cable 4 The female thread 411 of the joint 41 is fitted, and a flange portion 12 is provided between the two male threads 11 region.

The two insulating bushings 3 are respectively disposed at two ends of the tubular conductor 2, and a through hole 31 is formed in the center of each of the insulating bushings 3, and the through hole 31 is connected by a coaxially extending inner diameter and a gradually expanding inner diameter. The portion 32 is configured to abut one end of the tubular conductor 2 in the guiding portion 32, thereby fixing and supporting the tubular conductor 2 when the tubular conductor 2 and the insulating bushing 3 are placed in the channel 10 of the body 1. In the channel 10 of the body 1.

Referring to Figures 3 and 3A, the two ends of the tubular conductor 2 respectively have three guide pieces 21 which are equally spaced apart by the slits 20, so that a receiving groove 22 is formed between the guide pieces 21 at each end of the tubular conductor 2. 2 is shown). The middle portion of each of the guide pieces 21 is slightly recessed into the accommodating groove 22 to form a flat bottom portion 23, and the flat bottom portions 23 are further convexly formed in the accommodating groove 22 to form an elongated arch-shaped convex portion. Edge 24.

Therefore, when the two ends of the body 1 are respectively connected to the joint 41 of a coaxial cable 4, the core wire 42 of the coaxial cable 4 can be inserted into the receiving groove at the two ends of the tubular conductor 2 via the through hole 31 of the insulating bushing 3. 22, the tubular conductor 2 is elastically clamped by the arcuate flange 24 of the guide piece 21 to the coaxial cable 4 core wire 42 inserted in the accommodating groove 22, so that the arched flanges 24 can be equally spaced The core wire 42 exerts a compressive force to form intimate contact between the arcuate flanges 24 and the core wire 42. At the same time, the core wires of the coaxial cables at both ends are electrically connected via the tubular conductor 2, and electrical continuity (not shown) is established between the shields of the coaxial cables at both ends thereof via the body 1.

The present invention has an arched flange projecting inwardly at the flat bottom of each guide piece, so that the clamping stress can be concentrated on the arched flange when the guide piece at each end of the tubular conductor clamps the coaxial cable core. And the stress generated by the clamping is evenly distributed over a large area to avoid elastic fatigue caused by the long-term compression deformation of the guide, and can pass through a relatively large diameter (such as When the core wire of 1 mm) is inserted and removed multiple times and then inserted into a core wire having a relatively small diameter (for example, 0.64 mm), the guide piece at each end of the tubular conductor still maintains a stable clamping force. Therefore, when the creation is connected to coaxial cable cores of various diameters (such as 0.64mm-1.07mm), the signal transmission loss of 1GHz frequency is within 30dB, and the signal transmission loss of 3GHz is within 25dB.

In summary, according to the above disclosure, the creation can achieve the intended purpose of creation, providing a coaxial cable capable of providing reliable electrical connection and maintaining good electrical contact while stably transmitting high frequency signals. The adapter is of great value for industrial use, and a new type of patent application is filed according to law.
