Abstract
The invention discloses a kind of electromagnetic compatibility outlet sleeve, including helical member, nylon inner core, triangle spring, housing and claw, one end of the nylon inner core is connected by seal with the helical member, one end of the housing is connected after installing the triangle spring with the other end of the nylon inner core, and the other end of the housing is connected with one end of the claw.The present invention, which using helical member screws rear inner tip slope and pushes the mode of claw then compressive seal, to fix cable and can bear stronger pulling capacity, the principle of seal is tightened up using claw can realize water-proof function, porous function is realized by seal perforate above-below direction threading, there is excellent electromagnetic compatibility characteristic simultaneously, more reliable, installation is faster.
Description
Technical field
The present invention relates to outlet sleeve technical field, more particularly to a kind of electromagnetic compatibility outlet sleeve.
Background technology
Nowadays the application of electromagnetic compatibility formula cable connector is very extensive, is connected cable shield and terminal box by electromagnetic compatibility cable connector so that electronic equipment neither disturbs miscellaneous equipment, while is not also influenceed by miscellaneous equipment.
Mainly comprising fields such as nuclear power station, railway, communication, petrochemical industry, car, electric power.Its major function is cable to be attached with fixed, while ensures the water resistance, fire resistance and electromagnetic compatibility function of its high request.So as to effectively form effective protection steady in a long-term to cable and equipment.
The metal shell of electrical equipment, steel reinforced concrete pole and metal shaft tower etc., because insulation damages are possible to powered, in order to prevent ground connection that this voltage jeopardizes personal safety and set, referred to as protective grounding.Protective grounding is a kind of security measures that electrical equipment and electric wiring most use in the low-voltage distribution system and power high voltage system of isolated neutral.
Existing electromagnetic shielded cable joint needs after electromagnetic shielding line layer is cut off in a pre-installation, outer section metal wire is taken out, and is roped, is connected with another piece-root grafting ground wire, make its ground connection, so that electric current is exported by joint, electromagnetic compatibility effect is played, because being rigid cooperation, easily weigh or break cable shield wounded, the shield effectiveness of joint is set to be affected, installation is complicated, and operation difficulty is big.
The content of the invention
The purpose of the present invention is that to solve the above problems and provides a kind of electromagnetic compatibility outlet sleeve.
The present invention is achieved through the following technical solutions above-mentioned purpose：
The present invention includes helical member, nylon inner core, triangle spring, housing and claw, one end of the nylon inner core is connected by seal with the helical member, one end of the housing is connected after installing the triangle spring with the other end of the nylon inner core, and the other end of the housing is connected with one end of the claw.
Currently preferred, the both sides of the housing are provided with internal thread boss.
It is currently preferred, the other end of the housing be provided with it is flat, it is described flat to be connected by O-ring seal with the housing.
The beneficial effects of the present invention are：
The present invention, which using helical member screws rear inner tip slope and pushes the mode of claw then compressive seal, to fix cable and can bear stronger pulling capacity, the principle of seal is tightened up using claw can realize water-proof function, porous function is realized by seal perforate above-below direction threading, there is excellent electromagnetic compatibility characteristic simultaneously, more reliable, installation is faster.
Brief description of the drawings
Fig. 1 is the configuration schematic diagram of electromagnetic compatibility outlet sleeve of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1：The present invention includes helical member 1, nylon inner core 3, triangle spring 4, housing 5 and claw 6, one end of nylon inner core 3 is connected by seal 2 with helical member 1, it is connected after one end installation triangle spring 4 of housing 5 with the other end of nylon inner core 3, the other end of housing 5 is connected with one end of claw 6.
As shown in figure 1, the both sides of housing 5 are provided with internal thread boss, screw 7 is screwed in boss screw thread
And clamping claw 6 simultaneously.
It is connected as shown in figure 1, the other end of housing 5 is provided with flat 8, flat 8 by O-ring seal 9 with housing 5.
In summary, the present invention, which using helical member screws rear inner tip slope and pushes the mode of claw then compressive seal, to fix cable and can bear stronger pulling capacity, the principle of seal is tightened up using claw can realize water-proof function, porous function is realized by seal perforate above-below direction threading, there is excellent electromagnetic compatibility characteristic simultaneously, more reliable, installation is faster.
The operation principle of the present invention is as follows：
The present invention coordinates joint electromagnetic compatibility structure for a triangle spring combination of housing, the structure combination of the electromagnetic shielding is put into cable connector, it is set to have outside the function of water proof and dust proof, the function of electromagnetic compatibility is added again, during installing and using, shielding clad cable will first be removed to be inserted into inside joint, then start to screw the nut of metallic cable joint, while locking cable, there is one to spring to axial mental and physical efforts, so that triangle spring shrinks to central axial direction, coordinate so as to form Elastic Contact with the electro-magnetic screen layer of cable, reach the effect of electromagnetic compatibility.
Such joint uses 5052 aluminium material bodies, fire-retardant V0 silicone rubber seal, silicon rubber O-RING, stainless steel triangle spring and aluminum helical member, improves electromagnetic compatibility characteristic, fire resistance, corrosion resistance, weatherability, the good electric conductivity of product.
Triangle spring uses stainless steel, after being cut using the spring of standard specification, puts it into frock, two is fixed together with Laser Welding, being taken out after drying can install into joint, both ensure that the intensity of the part, and met the electric conductivity of the part again.
Seal and O-ring seal use silicon rubber, good sealing, ensure waterproof seal of the product in the range of locking wire.Aluminum cap is molded using die casting and Vehicle Processing, ensures good precision and intensity.
Those skilled in the art do not depart from the essence and spirit of the present invention, there can be various deformation scheme to realize the present invention, it the foregoing is only preferably feasible embodiment of the invention, not thereby the interest field of the present invention is limited to, all equivalent structure changes made with description of the invention and accompanying drawing content, are both contained within the interest field of the present invention.
