Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the end of a coaxial electrical winding. [Prior Art] A σ coaxial cable is generally provided with a second wire and a shielded wire in a cable (also known as a shielded wire). The seal layer). Specifically, on the central axis, the connector, the core member, and the shielded wire are connected to the grounding member by an insulator, a mesh shielding wire, a coating insulator, and a connector connected to the electronic device. For example, the cover): At this time, the shield wire is connected to the cover or the like for connection or welding. Here, the press-fit connection is sandwiched between a pair of sheets, and is fixed to the metal sheet while being fixed to the coaxial cable. ^ The above press-fit connection or soldering has the following problems. If you want to connect and fix each-coaxial cable to be packed. 5 axis power, € m can maintain the electrical connection state, and most f connections are difficult. Therefore, the number of dead cables required to connect the shielded wires is increased. This has manufacturing costs and labor. In addition, the welding is also required to be connected to the above-mentioned crimping connection cables, and the number of working processes is increased. The soldering cable evenly fuses the solder so that there is a problem of quality control in the connection of each coaxial cable. A connector that discloses such a technique is disclosed in Japanese Laid-Open Patent Publication No. H-59575, No. Hei 5-55454. As the core of the wire, the core is arranged with a core wire and a concentric circle. In order to connect such a line to the contact, the exposed portion of the conductive metal shroud that has been pressed out is firstly pressed and connected to the metal piece to simultaneously reduce the coaxial power: the number of working processes is high. Similarly, because each coaxial connection must be in a state of coaxial connection, the patent is also open.

At the same time, the shielded wire is connected to the first and the second coaxial connector, and the engaging protrusion of the first ▲ = exposed state is inserted into the groove, and the second cover is connected to the groove. As a result, $ is pressed, spliced, ς = grounded together with the shaft cable ground connection (shield line) by the snap protrusion: = inside: the shield can be electrically connected to the first and the first The second hold is maintained, that is, the cable ground connection is firmly fixed and held in the groove. ~Under, the coaxial connector can be used coaxially, and only the second fixed number of the electron mirror 1 cable connection = 乍 can be greatly reduced. * The processing process of the second cover cable is the connection of the retaining connector to the outside of the inlet, the snapping joint can be engaged, thereby using the screen of the cable to locate the necessary precision. 4) It is so advantageous to make the coaxial electrical component correct, such as the manufacture of the soldering connector, to form the exposed coaxial cover into a recessed groove, and in turn, the upper projection portion protrudes beyond the inlet portion. , combined with the Ministry at this time, the shape of the thinning is simple The connector is formed by the uniform fusion of only the wire and the _ if the control connection is made to be able to slide with the first cover member, and the manufacturing is formed to be narrow, so that the coaxial electric card can be inserted. In combination with the cover, it is preferable that the engaging projections are connected to the second cover by the process of mechanical connection, and the manufacturing tolerances of the various components can be further improved. Lifting the groove in the phase of the connecting member to make the clamping simple. The cable in the groove of the groove inlet is firmly grooved, and the first portion is formed to protrude toward the inset, and in the state of the shielding line, The two protrusions extend into the narrow portion and are wide inside, and the card engaging protrusion is not fixedly held by the groove and the second cover is firmly outside. The tip end of the extending direction is integrated into the groove to become a The connector, when a plurality of coaxial cables are formed as parallel cables arranged in parallel on the same plane, may correspond to the arrangement 13 of the same cable in the flat cable, forming a plurality of grooves in the first cover, and second The cover forming shovel each protrudes into and engages Most of the plurality of recessed grooves are engaged with the protrusions, whereby the grounding of the shielding wire is connected to the corresponding groove in the state in which the coaxial cable shielding wires are exposed, and only the second cover can be slid to be engaged The protrusion is formed in the corresponding groove and is easy to manufacture. 1288515 V. INSTRUCTION DESCRIPTION (5) IV. [Embodiment] The invention is a preferred embodiment of the present invention. Figure 2 to Figure 4 shows the connection to: ίί cable construction. Flat cable FC, as shown in Figure 2 (A), is made by tape 27 to hold a plurality of very thin coaxial (4) joints in parallel on one plane. The side clamps the number of coaxial coaxial cables 20, and can also be set on only one side. This is the structure of the 7 麻 Γ Γ Ϊ 20 as shown in Fig. 2 (Β), which is provided in multiple roots (in the ^ Η Χ亟The core wire 2 1 is made of an insulating material; 2 = 丨"; layer (the first insulating covering gamma, on the inner peripheral side, ii i = the wire is wound into a cylindrical shielding wire in the spiral direction) The outer peripheral side insulating coating straight layer 24 is formed on the outer periphery of the four screens 1 and 23, and the outer peripheral side insulating coating layer 24 is formed.
