Detailed Description

Referring to fig. 1 and fig. 2, a wire connection structure 100 according to a first embodiment of the present invention includes two wires 110, two plugs 120, and a fixing sleeve 130. For ease of illustration, only one wire 110 and one plug 120 are shown in FIG. 1. The two plugs 120 are actually the same male plugs, the fixed sleeve 130 is a female socket, and both ends of the fixed sleeve 130 are provided with insertion holes 132 for inserting one plug 120 respectively to electrically connect the two plugs 120.

As shown in fig. 3, 4 and 5, the electric wire 110 includes a plurality of metal cores 112,114 and 116 arranged in parallel. The surfaces of the metal cores 112,114,116 are coated with an electrically insulating layer, which may be an insulating varnish or plastic. Where the electrically insulating layer is plastic, the plastic covering the metal cores 112,114,116 may be integrally formed, but separate the metal cores 112,114,116 to form the over-mold wire. In addition, the electrical insulation of the metal cores 112,114,116 is stripped at least in the front portion.

As shown in fig. 3, 4 and 5, the plug 120 has a plug portion 122 and a plurality of through holes 124. The through holes 124 extend through both ends of the insertion part 122 in parallel with each other. The number of perforations 124 is the number of mating metal cores 112,114,116, and as shown the number of metal cores 112,114,116 is three, the number of perforations 124 is also three. The front ends of the metal cores 112,114,116 respectively pass through the through holes 124 and are folded back and flatly attached to the surface of the plug portion 122 to form a plurality of terminals 126, without welding the front ends of the metal cores 112,114,116 to the terminals 126 by other welding means. The surface of mating portion 122 may be provided with a plurality of grooves 122a to locate terminals 126 formed by the reverse folding of cores 112,114, 116. The three metal cores 112,114,116 shown are exemplary only and are not intended to limit the number of metal cores 112,114,116 and perforations 124. Meanwhile, the number of the through holes 124 may be larger than the number of the metal cores 112,114,116, and at this time, a part of the through holes 124 will be left without the metal cores 112,114,116 passing through.

As shown in fig. 1 and 2, the fixing sleeve 130 is a hollow structure, and has insertion holes 132 at both ends, and a plurality of electric conductors 134 are disposed in the fixing sleeve 130 and extend from one insertion hole 132 to another insertion hole 132. The shape of the electrical conductor 134 is not limited as long as it extends from one jack 132 to another jack 132 and is isolated from each other and is not in contact conduction. In addition, the electrical conductors 134 are equal in number to the terminals 126, i.e., to the metal cores 112,114, 116.

As shown in fig. 2, the mating portion 122 of the plug 120 is adapted to be inserted into the receptacle 132 of the retaining sleeve 130 such that the terminals 126 contact the electrical conductors 134. This allows the electrical wires 110 connected to the two plugs 120 to be mechanically and electrically connected through the electrical conductors 134. The metal cores 112,114,116, which are folded back as terminals 126, can now be held by the fixing sleeve 130 with a higher resistance to tearing than the welding. Meanwhile, the two plugs 120 are covered by the fixing sleeve 130, so that they are effectively waterproof and insulated.

In addition, the two plugs 120 respectively have at least one fixing buckle 121. The fixing sleeve 130 has a fastening hole corresponding to the fixing buckle 121. When the inserting portions 122 of the two plugs 120 are inserted into the fixing sleeves 130, the fixing buckles 121 can be buckled into the buckle holes, so that the two plugs 120 can be tightly combined with the fixing sleeves 130 without falling off.

As mentioned above, the form of the electrical conductor 134 is not limited, and the following examples illustrate the form of the electrical conductor 134 without limitation.

As shown in fig. 6, a fixing sleeve 130 according to a second embodiment of the present invention can be applied to the wire connecting structure 100 of the first embodiment.

As shown in fig. 6, the fixing sleeve 130 includes an upper housing 130a and a lower housing 130b that are separable to facilitate installation of the electrical conductors 134. The fixing sleeve 130 has a plurality of mounting slots 136 formed therein, the mounting slots 136 are located in the lower housing 130b, and each mounting slot 136 extends from one of the insertion holes 132 to another of the insertion holes 132. The electrical conductors 134 are metal strips, which may be circular, oval, rectangular, etc. in cross-section, secured in mounting slots 136. The metal strip can be fixed by using a clamping block, viscose glue and the like as long as the metal strip can be fixed. In practice, the metal strip may be a stripped wire 110, i.e., a metal core 112,114,116 that is cut to the appropriate length.

As shown in fig. 7, a fixing sleeve 130 according to a third embodiment of the present invention can be applied to the wire connecting structure 100 of the first embodiment. The fixing sleeve 130 of the third embodiment also has separable upper and

lower housings

130a, 130b to facilitate installation of the electrical conductors 134. The electrical conductors 134 may be metal domes that are compressibly deformable at both ends to facilitate contact with the terminals 126. The metal spring pieces are fixed in the fixing sleeve 130 in parallel with each other and extend from one insertion hole 132 to the other insertion hole 132. The metal elastic sheet can be fixed by using a clamping block, an adhesive and the like as long as the metal elastic sheet can be fixed. As shown in the figure, the lower housing 130b may be provided with fixing posts 133 for passing through the fixing holes 134a of the metal dome (the electrical conductor 134), so as to fix the metal dome (the electrical conductor 134) on the lower housing 130 b. When the upper housing 130a is combined with the lower housing 130b, the metal dome (the electrical conductor 134) is fixed in the fixing sleeve 130.

As shown in fig. 8, a fixing sleeve 130 according to a fourth embodiment of the present invention can be applied to the wire connecting structure 100 of the first embodiment. As shown, the fixing sleeve 130 further includes a circuit board 135, and the electrical conductors 134 are printed traces on the circuit board 135, and the printed traces can extend parallel to each other at two ends of the circuit board 135. The circuit board 135 is fixed in the fixing sleeve 130, so that two ends of the circuit board 135 respectively correspond to the two jacks 132, and the printed traces extend from one jack 132 to the other jack 132. The printed traces are used to contact the terminals 126 of the plug 120 to electrically connect the two wires 110.

As shown in fig. 8, besides the electrical conductors 134 for bridging, the fixing sleeve 130 may also be provided with electronic elements 137, such as resistors and transistors, connected to one of the electrical conductors 134, so as to adjust the electrical connection state between the two plugs 120.

Referring to fig. 9 and 10, a fixing sleeve 130 according to a fifth embodiment of the present invention is applied to a wire connection structure 100.

As shown in fig. 9 and 10, the fixing sleeve 130 has a hollow structure and has insertion holes 132 at both ends. The circumferential surface of the fixed sleeve 130 is provided with a window 131, and an inner wall surface 139 of the fixed sleeve 130 is exposed. The inner wall surface 139 is provided with a plurality of fitting groove grooves 139a, and the plurality of fitting groove grooves 139a are arranged in parallel with each other and extend from one insertion hole 132 to the other insertion hole 132. Meanwhile, both ends of each fitting groove 139a are respectively provided with a fitting hole 139 b. The electrical conductors 134 are substantially the same length as the keyway or slightly longer than the keyway. Meanwhile, both ends of the electric conductor 134 are respectively provided with bent portions 134 b. The electric conductor 134 is embedded in the embedding groove 139a, and the bent portions 134b are respectively inserted into the embedding holes 139b to fix the electric conductor 134 on the inner wall surface 139, and at the same time, protrude from the inner wall surface 139. When the length of the electrical conductor 134 is greater than the length of the embedded groove 139a, the electrical conductor 134 can be bent to form a protruding elastic structure on the inner wall surface 139.

Referring to fig. 11, 12 and 13, the fifth embodiment also provides a plug 120. Plug 120 has a mating portion 122 and a through hole 124. Unlike the previous embodiments, the fifth embodiment differs from the previous embodiments in that the plug 120 has only a single, larger perforation 124, while the multiple metal cores 112,114,116 of the supply line 110 pass through. At this point, the metal cores 112,114,116 need to be wrapped with an electrically insulating layer 110b to avoid shorting to each other in the perforations 124. The electrical insulation layer 110b at the front ends of the metal cores 112,114,116 is stripped off and folded back to be flatly adhered to the surface of the plug portion 122, so as to form a plurality of terminals 126,

as shown in fig. 9, 10, 11 and 12, the insertion portion 122 is provided with an elastic hook 128, and a guiding groove 132a is formed at the edge of the insertion hole 132 of the fixing sleeve 130 and extends toward the window 131.

As shown in fig. 14, when the inserting portion 122 is inserted into the inserting hole 132, the guiding slot 132a can guide the elastic hook 128 to move toward the window 131 and buckle the edge of the window 131, so as to fix the plug 120 to the fixing sleeve 130 and allow the terminal 26 to contact the metal conductor 134. When the plug 120 is to be removed, the elastic hooks 128 can release the plug 120 and pull out the plug 120 only by the portion of the elastic hooks 128 exposed out of the insertion holes 132.

As shown in fig. 15, the window 131 is mainly provided for installation of the metal conductor 134, and when the metal conductor 134 is installed, the window 131 can be closed by a sealing member 131a so that the metal conductor 134 inside is not exposed. In the case where the plug 120 is not required to be assembled or disassembled, the sealing member 131a may be an adhesive, such as a photo-curing adhesive, and may seal the entire fixing sleeve 130 to improve the waterproof effect.

Through the above embodiment of the present invention, the plurality of wires 110 can be connected in series quickly and continuously without welding operation, and particularly, the present invention is applicable to a series lamp circuit to quickly extend the length of the series lamp circuit. Through the fixing sleeve 130, the two wires 110 are mechanically and electrically connected, and the fixing sleeve 130 can provide a covering protection to achieve the purpose of insulation and water resistance.
