Embodiment
Electric switch of the present invention is with the embodiment 1 of conductive connecting device: as shown in Figure 1; This conductive connecting device comprise the fixing insulating basin 1-2 of the port of housing 1-1, housing 1-1, insulating basin 1-2 go up the connection inserts 1-3 that is provided with, connect inserts 1-3 go up contact base 1-5, contact base 1-5 through the fixing column of attachment screw 1-4 and connect on the periphery that is embedded the insulation guide ring 1-7 and the spring touch finger 1-8 that install on the periphery of fixing radome 1-6, contact base 1-5 between the inserts 1-3, is plugged in contact base 1-5 and with the contact tube 1-9 of insulation guide ring 1-7 and spring touch finger 1-8 contact matching; Wherein, Contact tube 1-9 is wholely set away from the link and the bus-bars conductor of contact base; Radome 1-6 have the closing in end 1-6-1 that is embedded between the connection inserts 1-3 of contact base 1-5 and insulation plate 1-2 and with the 1-6-2 that dehisces to hold of the outer peripheral face matched in clearance of contact tube 1-9; Offer the fingertip mounting groove 1-5-1 of installing spring touch finger 1-8 and the guide ring mounting groove 1-5-2 of installing insulation guide ring 1-7 on the periphery of contact base 1-5, and spring touch finger 1-8 exposes from the outer peripheral face of contact base 1-5 all with insulation guide ring 1-7; And be used for using hole 1-5-3 with the screw on the connection inserts 1-3 that contact base 1-5 is fixed on insulating basin 1-2 offering on the contact base 1-5 through attachment screw 1-4; And screw along the extending axially of contact base 1-5, convexes with the limiting stand 1-5-4 away from the side of guide ring mounting groove 1-5-2 that is in fingertip mounting groove 1-5-1 with hole 1-5-3 on the outer peripheral face of contact base 1-5.
Present embodiment in use; Earlier contact base 1-5 is fixed on being connected on the inserts 1-3 of insulating basin 1-2 with radome 1-6 through attachment screw 1-4; To insulate then guide ring 1-8 and spring touch finger 1-7 is installed in respectively in the guide ring mounting groove 1-5-2 and fingertip mounting groove 1-5-1 that offers on the contact base 1-5; Contact tube 1-9 is inserted among the radome 1-6, the inside pipe wall that makes contact tube 1-9 simultaneously respectively with insulation guide ring 1-8 and spring touch finger 1-7 contact matching; Limiting stand 1-5-4 and contact base 1-5 are structure as a whole, the main purpose that limiting stand 1-5-4 is set be prevent contact tube 1-9 install with use in the transition displacement, and impact shield cover 1-6 causes radome 1-6 to be out of shape and influences the function of electric field shielding.
Radome 1-6 is formed by thin-wall metal sheet material spinning or is cast as thin-wall construction as required in the present embodiment, and the electric field structure that the profile of radome 1-6 is optimized as required and deciding; Fingertip mounting groove 1-5-1 quantity (is containing one) more than one, (contains four) below four, and concrete quantity determines according to the through-current capability between required contact tube 1-9 and the contact base 1-5; Contact tube 1-9 and bus-bars conductor are wholely set; And contact tube 1-9 is the hollow tube of being processed by electric conducting material; Like electric conducting materials such as aluminium, aluminium alloy, copper, copper alloys; Because exempted contact tube 1-9 is welded on the structure on the fixed contact main body (not shown),, thereby has reduced the processing and manufacturing cost and practiced thrift metal material so contact tube 1-9 also can be with processing through thin-walled material such as simple finished pipe profile; Insulation guide ring 1-7 is installed in the side of fingertip mounting groove 1-5-2, is used to guide the correct contact spring fingertip of contact tube 1-9 1-8, avoids contact tube 1-9 to depart from the axial of contact base 1-5 simultaneously.
Present embodiment is primarily aimed at through-current capability and requires low, low to the overall dimension required precision of contact base 1-5 conductive connecting device; Because of self sectional area of contact base 1-5 in this structure little; The screw of being inconvenient to be provided with the counter sink structure is used hole 1-5-3, thereby bolt uses hole 1-5-3 to be clear opening, and bolt can be one or at least two with the quantity of hole 1-5-3; When bolt uses hole 1-5-3 to be one; Bolt is with hole 1-5-3 and the coaxial setting of contact base 1-5, and when bolt used hole 1-5-3 at least two, bolt made progress with the week that hole 1-5-3 is evenly distributed on contact base 1-5.
Electric switch of the present invention is with the embodiment 2 of conductive connecting device: as shown in Figure 2; The difference of present embodiment and embodiment 1 is; In the present embodiment; The screw of offering on the contact base 2-5 uses hole 2-5-3 to be counter sink, and screw has the countersunk head section 2-5-4 on every side that is used to be wrapped in attachment screw 2-4 head with hole 2-5-3.Screw has two with hole 2-5-3, and two screws are provided with hole 2-5-3 each other at interval.
Area because of self cross section of contact base 2-5 in the present embodiment is bigger; The above spring touch finger 1-7 of two circles can be installed on the periphery because of this contact base 2-5 again more; Be set to counter sink so offer screw on need contact base 2-5 with hole 2-5-3, to reduce the length of attachment screw, through the head 2-1-1 of contact base 2-5 shielding attachment screw 2-4; Increase the uniformity of Electric Field Distribution, reduce the sole mass of contact base 2-5.In addition, screw also is to decide according to actual conditions with the concrete quantity of hole 2-5-3.
Electric switch of the present invention is with the embodiment 3 of conductive connecting device: as shown in Figure 3; The difference of present embodiment and above-mentioned two embodiment is; Offer on the contact base 3-5 along its axially extended blind hole 3-5-3, and screw just is opened on the cecum 3-5-5 hole wall of blind hole 3-5-3 with hole 3-5-4.
Present embodiment is primarily aimed at the demanding conductive connecting device of through-current capability; Because of self sectional area of contact base 3-5 in this structure big; So can contact base 3-5 be offered blind hole 3-5-3 through manufacturing process such as casting, forging, machine works on contact base; Reducing the length of bolt, and can shield the head 3-1-1 of attachment screw 3-4, reach the purpose of uniform electric field distribution through this blind hole 3-5-3 with hole 3-4; And wherein the concrete quantity of attachment screw 3-4 is no less than three generally speaking, and is evenly distributed on the cecum 3-5-5 end face of blind hole 3-5-3.
In the above-described embodiments, the fingertip of installing in the fingertip mounting groove is a spring touch finger, and in other embodiments, this spring touch finger also can be replaced with the watchband fingertip.
In the above-described embodiments; Contact base is fixed on the connection inserts on the insulating basin through attachment screw; In other embodiments; Contact base also can be fixed on the connection inserts on the insulating basin through modes such as welding, bolt connections, and the connected mode that wherein bolted connected mode is fixedly connected with attachment screw is similar, belongs to the technology that art technology person knows and therefore repeats no more.
In the above-described embodiments; The limiting stand and the contact base that are used to stop contact tube on the periphery of contact base, to move that are provided with on the contact base are wholely set; In other embodiments; Other elements such as the back-up ring that limiting stand is provided with on also can the periphery for contact base, interstage sleeve, nut replace, and these elements are arranged on the mobile prior art that belongs to that stops contact tube on the periphery of contact base, therefore repeat no more.
