Connector for coaxial cable

Abstract

A coaxial cable connector to which coaxial cables including two kinds of coaxial cables having different outer diameters can be easily connected and whose height is reduced. The coaxial cable connector (10) has a housing (3), first, second, and third terminals (4, 5, 6), and a shell (7). The horizontal positions of connection pieces (51, 61) of the second and third terminals (5, 6) are lower thanthe horizontal position of a connection piece (41) of the first terminal (4) by H1 and H1 + H2, respectively. This reduces gaps between the upper end surfaces of first and second coaxial cables (1, 2) and a top plate (71) when the cables are received in first and second cable receiving grooves (31, 32). Further, a contact piece (63) is provided next to the connection piece (61) of the third terminal (6) with a connection piece (62) in between, and the upper end surface of the contact piece (63) is placed below the bottom surface of the third groove (31), on a horizontal plane above the horizontal plane of the connection piece (61). This secures the depth of insertion necessary for connection to a mating connector (100).

Description

technical field [0001] The present invention relates to a connector for a coaxial cable (for example, a plug for a coaxial cable) used in various electronic devices such as information terminals and mobile phones. In particular, it relates to a connector suitable for coaxial cables of extra-thin wires. Background technique [0002] In the conventional ultra-thin wire coaxial cable connector, the respective ends of the inner conductor and the outer conductor of a plurality of ultra-thin wire coaxial cables are respectively soldered to the connecting piece of the signal side terminal and the grounding terminal. Therefore, there are problems in that man-hours increase and it is difficult to narrow the pitch between terminals. [0003] In order to achieve the above-mentioned reduction in man-hours and narrow pitch between terminals, the following proposals have been made. [0004] That is, the inner conductor, the inner insulating coating, and the outer conductor are sequentia...

AI Technical Summary

Problems solved by technology

[0012] However, in Figure 9 The coaxial cable connector 200 shown has the features of reducing man-hours, narrowing the pitch between terminals, and reducing the height of the connector. Coaxial cables (such as thin-wire coaxial cables) are difficult to wire together with the same connector.

[0013] In the case of wiring on the same connector, in order to facilitate the assembly work, it is necessary to arrange the connecting pieces of all the wiring terminals on the same reference plane. When wiring on the lugs of the wiring terminals of the same connector, there is a problem that the height of the connector becomes larger.

[0014] Moreover, in order to align the center conductors of a plurality of coaxial cables with different outer diameters on the same reference plane, only the outer diameter of the coaxial cable with a smaller outer diameter (such as a coaxial cable with a very thin wire) should be aligned with the outer diameter. When aligning a coaxial cable with a large diameter (such as a thin-wire coaxial cable), the size of the connector is increased, and there is a problem that miniaturization cannot be achieved.
