The wire clamp is used. » In the above configuration, the surface of the metal guide plug can be read with a gold layer for good electrical conductivity. In the above configuration, the surface of the metal collar may be a gold ore layer for good electrical conductivity. [Embodiment] In order to achieve the above objectives, the technical means adopted by the present invention and the achievable merits are as follows: The best examples of the best practices are described below in conjunction with the drawings, so that the review committee can fully understand the creation. A 7 M291138 Please refer to the third and fourth figures. The wire fast connecting device of the present invention includes: - the first connecting piece 丨 'with a chamber n 'the other end is provided with a perforation for one The wire 62 is inserted through, and the inner ring wall of the chamber 11 has an internal thread m, and the outer shape of the chamber 11 is a shape (for example, a hexagonal shape) for the user to hold the hand; the metal conductive column is a metal cylinder The shape of the lining is formed inwardly - the chamber 3 is sealed, and then the conical soil is formed. The metal conductive plunger 3 can be gold-plated as a whole, so that the surface is plated with gold to ensure good conductivity. After the wire 62 is inserted into the chamber of the first connection, the elastic member 2 can be sleeved on the electric wire 62, and the chamber 31 of the metal conductive plunger 3 covers the electric wire 62. The exposed wire segment 622 is machined and stamped from the outside of the metal conductive plunger 3, so that the metal conductive plug 3 and the exposed bare wire segment are slightly open-field=solid-bonded, and at this time, the end of the piece 2 That is, the metal conductive plunger 3 is abutted, and the other creeping force is against the inner wall of the chamber u of the first connecting member, so the bomb is borrowed. The elastic force of the piece 2 is such that the conical duck of the 5 彡 metal guide plug 3 protrudes outside the chamber U of the first connecting piece 1 (as shown in the fourth figure); the second connecting piece 5' The outer wall also has a corner-shaped portion (for example, it is set to be hexagonal to facilitate the user's hand to rotate, and the inside is divided into a first - chamber chamber and a second = chamber 52, the second chamber 52 and the first - Between the chambers 51, there is a narrowing of the inner diameter. After the electric wire 61 enters from the second chamber 52f, the insulating sheath 6ΐι cannot pass through 俨=53 'so does not enter the first chamber 51' However, the exposed wire of the electric wire 61 can pass through the display portion 53 (the neck portion 53 further guides the exposed wire segment 612 and enters the inside of the second to the 51th portion). The external thread ' can be screwed into the internal thread (1) of the first connecting member 1 (please refer to the M291138 shown in FIG. 5), and the first chamber 51 is provided with a symmetrical notch 54 at the outer wall port. And one gold: set of %: ' can be d into the first chamber of the second connector 5 in close contact, the metal sleeve jade 4 is provided with a chamber 41, the card contains /Π > one The opening 42 faces the first connecting member J, and the other end is an outer wide (four) obliquely cylindrical through hole 43 through which the bare wire segment 612 passing through the second connecting member (4) The perforation must enter the chamber 41 to stay (as shown in the fourth figure), so the second connecting member 5 is held so that the inner metal collar 4 is sleeved against the metal conductive plunger 3 of the connector 1 And the first and second connecting members 1 and 5 are screwed to each other, and the metal collar 4 and the gold electric plug 3 can jointly enter the raw material of the chamber of the metal collar 4 Segment 612 = Axis ' achieves good contact conductivity; the metal collar 4 as a whole can also be previously subjected to a gold plating process to provide a gold-plated surface to ensure good electrical conductivity. When the outer ring wall port of the first chamber 51 is provided with a symmetrical notch 54' so that the golden shame ring 4 is received in the first chamber 51, the metal collar 4 will be exposed. The function is to facilitate the user to take out the metal collar 4 from the yoke 54 (ie, detached from the second connecting member 5), so that the branch can be selected to accommodate a different size. 4; Please refer to the figure 6 shown in the figure above. The metal collar 4 series can be designed with various sizes to allow the user to select the first cavity of the second connector 5. In the chamber 51, the purpose is to match the wire clamps having different thicknesses. f, in the sixth figure, as shown in (A), (8), (6), (8), the inner diameter of the opening 42 of the cavity of the metal collar 4 to 41 can be made into 屮, %, in order from small to large. %, heart, and the smaller inner diameter of the inner end of the perforation 43 is sequentially made from S1 s2 's3, s4', and the larger inner diameter of the outer portion of the perforation 43 is unchanged, so the user M291138 If the electric _ exposed wire segment to be connected is used to hide the occupant, the metal ferrule of the display (A) is used together; as for the % & select b, the exposed wire segment of the wire to be connected, If the spring is larger, it may be that the middle of the sixth figure (D) is selected. 》',,, and 'As for the structure of the excellent ^ extracted by the implementation of the outline, the creation has the following U in the creation, the two wires 61, 62 ^ actual connection is made of metal: ΐ: the ferrule 4 is achieved and the exposed wire segment f of the wire 61 is sandwiched between the ferrule 3 and the metal collar 4, so the contact conductivity is true and good; the on-mouth 'metal conductive plunger 3 and The surface of the metal collar 4 is treated with a gold plating layer, so that the surface stability is good, and the contact conductivity is fully exerted. Coin, 2. Because the metal conductive plunger 3 and the metal collar 彳 are responsible for the connection between the central and the second wire of the wire. Therefore, the longitudinal plastic part is slightly deformed because it is immersed in high temperature oil, but it will definitely not affect the metal. Conductivity of the conductive plug 3 and the Jinxian ring 4 with electricity and _.曰 Zeng Qian 3. Because in the initial combination, the elastic force of the elastic body 2 can push the conical end of the metal V electric column base 3 to significantly protrude the first connecting member! Outside the chamber η (as shown in the fourth figure, when the metal collar 4 holding the second connecting member 5 seeks to be inserted into the metal conductive column 3, the target is extremely clear, and it is easy to be aligned and screwed. There is no such thing as a lack of proper cause of the failure of the positive screwing. 4. Because the elastic force of the elastic member 2 exists, the first and second connecting members 1, 5 are screwed together and the miscellaneous The elastic force of the piece 2 is forced by the first and second connecting pieces, and the inner and outer threads of the 5 and 51 are finely combined. Therefore, there is no concern that the 10 M291138 is loosened due to vibration. The outer portions of the first and second connecting members 1, 5 are provided with angular portions, so that it is convenient for the hand-operated operation to perform the connecting action. As a whole, since the structural composition of the present creation has not been seen before, and the utility has not been known before the application. It is not obvious to anyone, so the patent application is filed according to law, and it is requested to review and give approval. It is really sensible.
