Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic assembly view of the present invention;
FIG. 2 is a schematic view of the construction of the sheath;
fig. 3 is a schematic cross-sectional view of the present invention.
Detailed Description
Referring to fig. 1 to 3, a moisture-proof electrical connection terminal comprises a tube seat 1 having an inner cavity, a taper shaft 2, and a spring 3 axially installed in the inner cavity of the tube seat 1 and capable of pushing the taper shaft 2 to move in the inner cavity, wherein the tube seat 1 is provided with a wire inlet hole seat 4 for placing and stopping the taper shaft 2, the tube seat 1 is sleeved with a moisture-proof sheath 5, two ends of the moisture-proof sheath 5 are radially provided with tightening bands 6, the tail end of the tightening band 6 is provided with a buckling hole 7, two ends of the moisture-proof sheath 5 are further provided with buckling columns 8, the tightening bands 6 are wound around two ends of the moisture-proof sheath 5, the buckling holes 7 are buckled on the buckling columns 8, during assembly, the sheath is firstly taken down from the terminal body and sleeved on a lead, then the lead is stripped to a corresponding length and inserted into the terminal until the lead is completely exposed, and finally the sheath is reset, and the lead is connected with the terminal, the one end suit that will prevent damp sheath is on the wire to it is taut around the round with tight hoop tape, will detain the hole lock on detaining the post, makes the both ends of sheath closely laminate on wire and terminal body, has good dampproofing and waterproofing effect, need not to adopt the instrument installation moreover, and the installation is simple and convenient.
Moisture-proof sheath 5 corresponds the one end of inlet wire hole seat 4 outwards extends the wire end 9 that has the suit wire, the diameter of wire end 9 is less than the diameter of moisture-proof sheath 5 body makes the wire end of moisture-proof sheath closely laminate with the wire of being connected, ensures the dampproofing and waterproofing effect of moisture-proof sheath, inlet wire hole seat 4 is installed to the one end of tube socket 1, and the other end is equipped with connecting piece 10, be equipped with connecting hole 11 on the connecting piece 10, can be used to be connected with power equipment's link electricity, certainly, in another embodiment, inlet wire hole seat 4 is all installed at the both ends of tube socket 1 for connect two wires.
Dampproofing sheath 5 with tight strap 6, detain post 8 integrated into one piece, production is convenient, reduces unnecessary assembly process, improves production efficiency.
The moisture-proof sheath 5 is made of a silica gel material, the tightening band 6 is made of a silica gel material, in the embodiment, the hardness of the silica gel is 45-70 degrees, the dustproof and waterproof grade of the moisture-proof sheath is IP57, the flame retardant grade is VO grade, and the impact voltage resistance is 40 KV.
When in use, a plurality of wires are well stripped and inserted into the wire inlet hole seat 4, the wires can be divided into umbrella shapes through the conical shaft 2, meanwhile, under the action of thrust, the conical shaft 2 moves backwards until the wires pass through the gap between the conical shaft 2 and the wire inlet hole seat 4, when the wires enter the tube seat 1 through the gap, the wires can be automatically bent and tightly attached to the inner wall of the wire inlet hole seat 4, the conical shaft 2 moves forwards automatically under the action of a spring after the wires enter the tube seat 1, and the gap between the conical shaft 2 and the wire inlet hole seat 4 is recovered to the minimum so as to lock the wires.
The terminal body has the following characteristics: (1) the vibration filtering effect is good; when the vibration of the track is transmitted to the terminal body through the lead, the conical shaft and the spring can retreat from a certain gap backwards, and the conical shaft and the spring can be restored to the initial state after the vibration is weakened to disappear, and the operation is repeated; the mechanism can effectively reduce the phenomena of stress concentration, abrasion, fracture and the like caused by vibration, and can avoid the phenomenon that the compression joint mode of the hydraulic pliers is looser and looser due to high-frequency vibration; (2) the installation is simple and convenient, and the current transmission is guaranteed; the structure can be installed by using very small external force, heavy hydraulic clamp compression joint is not needed at all, and each lead is tightly attached to the inner wall of the terminal after entering around the conical shaft, so that current can be smoothly transmitted, the contact resistance is low, and the temperature rise is correspondingly lower than that of a compression joint mode; (3) the connection is reliable; because each wire automatically bends and deforms after entering the product and is uniformly distributed around the wire, when an outward force acts on the wire, the conical shaft automatically contracts along with the wire, the gap is reduced, the wire is very difficult to pull out, and a reliable connection effect is obtained.
Adopt above-mentioned binding post cooperation dampproofing sheath, make it can obtain reliable power transmission guarantee, low temperature rise, auto-lock, outstanding filtration shake and dampproofing, dustproof effect again when quick connection, alleviate intensity of labour simultaneously greatly, have very huge economic value.
The above embodiments do not limit the scope of the present invention, and those skilled in the art can make equivalent modifications and variations without departing from the overall concept of the present invention.
