DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the protection scope of the utility model. Obviously, the embodiments described in the utility model are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Embodiment 1, the specific structure of the utility model is as follows:

[0032] Please refer to the attached Figure 1-5 The utility model discloses an HDMI cable with a splicing structure, comprising a first HDMI main cable 1 and a second HDMI main cable 3, wherein the first end of the first HDMI main cable 1 and the first end of the second HDMI main cable 3 are both HDMI heads, and the HDMI cable further comprises at least one splicing cable 2, wherein the two ends of the splicing cable 2 can be respectively plugged and connected with the second end of the first HDMI main cable 1 and the second end of the second HDMI main cable 3, and the wire 28 of the splicing cable 2 is a round wire.

[0033] The splicing line 2 includes a male plug and a female plug that are arranged at both ends of the line body and can be plugged in and connected, and a locking ring that can lock and loosen the male plug and the female plug. The male plug and the female plug can be plugged in and connected, so multiple splicing lines 2 can be connected end to end to extend the length of the HDMI line. The function of the locking ring is to lock the male plug and the female plug. The operation is that after the male plug and the female plug are plugged in and connected, the locking ring is rotated at an angle so that the locking ring locks and fixes the male plug and the female plug.

[0034] The second end of the first HDMI main line 1 is the male plug and the male plug of the first HDMI main line 1 is provided with a locking ring; the second end of the second HDMI main line 3 is the female plug. When the outdoor display screen is not far from the host, the splicing line 2 is not required, and the male plug of the first HDMI main line 1 and the female plug of the second HDMI main line 3 are connected by plugging and then fixed by the locking ring. The first HDMI main line 1 is connected to the host, and the second HDMI main line 3 is connected to the outdoor display screen.

[0035] Embodiment 2:

[0036] The following are the specific structures of the male plug, female plug and locking ring.

[0037] like Figure 3 As shown, the male plug includes a male terminal fixing shell, a first rubber-coated shell 211, and a male terminal. The male terminal is positioned in the male terminal fixing shell and connected to the first end of the wire 28. Then, the male terminal and the wire 28 are covered with rubber at the connection point through a rubber-coating process to form the first rubber-coated shell 211. Specifically, the male terminal and the first end of the wire 28 are fixed by soldering.

[0038] The male terminal is a 19-pin terminal, in which three first thick terminals 29 and 16 thin terminals 210 are provided, wherein the three thick terminals 29 have sockets. The 16 thin terminals 210 are all solid terminals. The first thick terminal 29 has two power supply terminals and a ground terminal, and the 16 thin terminals 210 are signal terminals, such as video image transmission signal terminals, sound signal transmission terminals, etc.

[0039] The male terminal fixing housing has a ring groove 212 on its plug-in side edge, and one end of the lock ring is rotatably sleeved in the ring groove 212. In order to enable the lock ring to be sleeved in the ring groove 212, at least two convex lumps 216 may be provided on the inner wall of the lock ring, and the convex lumps 216 are clamped in the ring groove 212 and can rotate the lock ring.

[0040] The female plug includes a female terminal fixing shell, a second rubber-coated shell 21, and a female terminal. After the female terminal is fixed to the female terminal fixing shell, it is connected to the second end of the wire 28 and fixed with solder, and then the second rubber-coated shell 21 is formed by rubber-coating at the joint between the female terminal and the wire 28 through the rubber-coating process. The plug end of the female terminal fixing shell has a 16PIN terminal fixing hole 25 and three C-shaped grooves 22. Each of the three C-shaped grooves 22 is provided with a second thick terminal 23, and the second thick terminal 23 is a solid terminal. The second thick terminal 23 is used to insert into the socket hole of the first thick terminal 29. The 16PIN terminal fixing hole is provided with a 16PIN socket terminal, and the 16 thin terminals 210 are plugged into the 16PIN socket terminals one by one.

[0041] The inner wall of the lock ring is provided with a protrusion 215, the side of the female terminal fixing shell is provided with a notch 214 for the protrusion 215 to slide into and a groove for the protrusion 215 to slide into, and the opposite sides of the groove are provided with two opposite arc strips 213, and the two arc strips 213 divide the groove into two sections. The outer wall of the lock ring is provided with at least one protruding shift block 27.

[0042] When multiple splicing wires 2 need to be spliced, the male terminal and the female terminal are plugged end to end and connected, and then the lock ring is rotated. The specific operation is: align the protrusion 215 of the lock ring with the notch 214 and enter the groove, and then rotate the lock ring to the left, so that the protrusion 215 on the lock ring squeezes through the two arc strips 213. Since the distance between the two arc strips 213 is less than the height of the protrusion 215 by 0.1-0.5mm, the protrusion 215 cannot slide out of the notch 214 without the action of external force, and the operation is simple.

[0043] In addition, the male terminal and the female terminal of the utility model are sealed by a sealing ring, thereby increasing the waterproof function.

[0044] In summary, the HDMI cable of the utility model adopts a splicable connection structure, which can lengthen the length of the HDMI cable and avoid excessive excess wires. The HDMI cable of the utility model is convenient to transport, because a plurality of spliced ​​wires are spliced, and the plurality of spliced ​​wires are easy to store after being disassembled. Since a relay connector is not required, the installation cost of the HDMI cable can be reduced.
