Abstract
The invention discloses a connecting terminal, which comprises a threading shaft, a first outer shell, a second outer shell, a first inner shell and a second inner shell. The threading shaft is inserted into the first outer shell, and is provided with a first threading hole. The second outer cover is provided with a second threading hole. The first and second outer shells are fixedly connected to form a first accommodation cavity. The first and second inner shells are accommodated in the first accommodation cavity, and are connected to form a second accommodation cavity. The first inner shell comprises a threading part with a third threading hole. The threading part is accommodated in the first threading hole, so that the first threading hole is communicated with the third threading hole. A fourth threading hole communicated with the second threading hole is reserved in the lateral surface of the second inner shell. According to the connecting terminal, water flowing into a gap between the threading shaft and the first outer shell is hard to flow into the second accommodation cavity, so that wires or electronic elements in the second accommodation cavity are prevented from being short-circuited due to the inflow. Therefore, the connecting terminal is high in waterproofness.

Main accompanying drawings specific embodiment of the invention below.
Refer to Fig. 1 and Fig. 2, the binding post 100 of an embodiment comprises threading axle 110, the first shell 120, second housing 130, the first inner casing 140, the second inner casing 150 and penetration pipe 160.Threading axle 110 wears the first shell 120 rotationally.The first shell 120 is fixedly connected with to form the first host cavity (figure is mark not) with second housing 130.The first inner casing 140 is fixedly connected with the second inner casing 150, jointly to form the second host cavity (figure is mark not).The first inner casing 140 and the second inner casing 150 are placed in the first host cavity.Penetration pipe 160 is wrapped in outside second housing 130.
It is cylindric that threading axle 110 is roughly, and its middle part offers the first through wires hole 111 passing through for cable.One end of threading axle 110 is formed with external screw thread 113.Threading axle 110 is connected with threaded fastener (figure is mark not) by external screw thread 113 after wearing the first shell 120, and threading axle 110 is rotatably connected with respect to the first shell 120.
The first shell 120 is roughly cylindrical.
It is cylindric that second housing 130 is roughly, and its middle part offers containing hole 131, offers the second through wires hole 133 on its side arm.The second through wires hole 133 is connected with containing hole 131.In the present embodiment, containing hole 131 is shoulder hole.
Refer to Fig. 3 and Fig. 4, the first inner casing 140 comprises cover body part 141 and threading portion 143.Cover body part 141 is roughly circle.Cover body part 141 middle parts are substantially vertically fixed in threading portion 143, and are contained in the first through wires hole 111 of threading axle 110.Threading portion 143 is roughly circular tube shaped, and it has the 3rd through wires hole 145.
The second inner casing 150 is for having the cylindrical box body of opening (figure is mark not).The cover body part 141 of the first inner casing 140 is closed in the opening part of the second inner casing 150.The side of the second inner casing 150 is formed with depressed part 151.The bottom of depressed part 151 offers the 4th through wires hole 153.In the present embodiment, the second inner casing 150 and the first inner casing 140 adopt and take eaves mode and couple together.
See also Fig. 2 to Fig. 4, while using binding post 100, first, the first inner casing 140 and the second inner casing 150 are coupled together, to form the second host cavity.The first inner casing 140 and the second inner casing 150 are positioned in the stub end of containing hole 131 of second housing 130.The first shell 120 is fixedly connected with second housing 130, forms the first host cavity.The first inner casing 140 arranges near the first shell 120, and the second inner casing 150 arranges near second housing 130.Threading axle 110 is worn to the first shell 120 rotationally, and be sheathed in the threading portion 143 of the first inner casing 140.The first through wires hole 111 is connected with the 3rd through wires hole 145.The 4th through wires hole 153 is connected with the second through wires hole 133.Penetration pipe 160 is wrapped in outside second housing 130, and is connected with the second through wires hole 133.One cable, successively through penetration pipe 160, the second through wires hole 133 and the 4th through wires hole 153, is electrically connected through the 3rd through wires hole 145 and the first through wires hole 111 another cable with last cable.Extraneous water flows to the first host cavity from the seam crossing of threading axle 110 and the first shell 120, is barred from outside the first inner casing 140 and the second inner casing 150, and is difficult to flow in the second host cavity.
The first inner casing 140 of above-mentioned binding post 100 is connected and forms the second host cavity of a sealing with the second inner casing 150, the threading portion 143 of the first inner casing 140 is contained in the first through wires hole 111 of threading axle 110, make the shipwreck flowing to from the gap between threading axle 110 and the first shell 120 to flow in the second host cavity, thereby avoid being contained in the wiring of the second host cavity or electronic component because of water inlet short circuit.Therefore, above-mentioned binding post 100 water proofing properties are better.
The second inner casing 150 and the first inner casing 140 are not limited to adopt and take eaves mode and couple together, and make extraneous shipwreck to flow to the second host cavity from the seam crossing of the second inner casing 150 and the second inner casing 140, and adopt and take eaves mode and mount and dismount convenience.Therefore, the first inner casing 140 of above-mentioned binding post 100 and the good waterproof performance of the second inner casing 150, and installation and removal are convenient.
Being appreciated that the second inner casing 150 and the first inner casing 140 are not limited to adopt takes eaves mode and couples together, and also can adopt alternate manner to connect, for example, and the modes such as engagement connection or welding.The 4th through wires hole 153 is not limited to be opened in the bottom of depressed part 151, and the depressed part 151 of the second inner casing 150 also can omit, now, and the through hole that the 4th through wires hole 153 forms for indent.
