Embodiment
In the present invention, switch cubicle embodiment is as shown in Fig. 1 ~ Fig. 4, and switch cubicle comprises contact box box body 1, conducting line row 2 and the fixed contact 3 being arranged in cabinet 6, and three is fixed together by corresponding fixed contact connection structure.Wherein conducting line row 2 is to be fixed on contact box box body 1 by corresponding line row screw 4, and the end face of line row screw 4 heads is provided with screwed hole 41.Fixed contact 3 is multidiameter shape, its diameter away from one end of conducting line row 2 is less than the diameter near one end of conducting line row 2, adopt this structure to be convenient to the connection with corresponding Mume flower contact away from one end of conducting line row, and near one end diameter of conducting line row, can meet more greatly the electric current demand of fixed contact.On fixed contact 3, along its axis direction, be provided with the through hole penetrating for corresponding fixed contact screw 5, described through hole is shoulder hole, shoulder hole is less near the aperture of one end of conducting line row 2, its end face forms the Stop structure that the head for fixed contact screw 5 coordinates along fixed contact axis direction block, and fixed contact screw 5 spinnings are in described screwed hole and by above-mentioned Stop structure, fixed contact is fixed on line row screw.Fixed contact 3 is provided with near the end face of conducting line row 2 one end the groove that the head for line row screw 4 enters, and to avoid when mounted the head of line row screw 4, makes fixed contact 3 and conducting line row 2 conductive contacts, easy for installation.
During assembling, first use line row screw 4 conducting line row 2 to be fixed on the inwall of contact box box body 1 correspondence; Then, make the part of the groove alignment line row screw 4 protrusion conducting line rows 2 of fixed contact 3 rear ends, fixed contact 3 is pressed on conducting line row 2; Finally, fixed contact screw 5 passed to the shoulder hole on fixed contact 3 and be tightened onto in the screwed hole 41 of line row screw 4 tail ends, completing the assembling of fixed contact 3.When the current class of switch cubicle need to be adjusted, with reference to the operation in tandem contrary with above-mentioned steps, can pull down fixed contact 3, now conducting line row 2 does not need dismounting, then with reference to above-mentioned steps, replaces with suitable fixed contact 3, easy to adjust.In addition, when the Mume flower contact of corresponding handcart and the distance of the engagement between the fixed contact in contact box are not time, fixed contact screw 5 and fixed contact 3 can be unloaded, with suitable copper bar pad between fixed contact 3 and conducting line row 2, then fixed contact 3 is fastening, reach the requirement that increases engagement distance.
Fixed contact connection structure in the embodiment that in the present invention, fixed contact connection structure embodiment is above-mentioned switch cubicle repeats no more herein.
In the above-described embodiments, the through hole in fixed contact 3 is set to the form of shoulder hole, relies on the Stop structure of the cascaded surface formation of shoulder hole to install for fixed contact screw; And fixed contact screw 5 is to screw on the screwed hole 41 that online row's screw 4 tail ends are installed, avoided establishing in addition hole on conducting line row, compact conformation.In other embodiments of the invention, Stop structure also can adopt other forms, the form of projection is for example set in through hole, and the mounting means of fixed contact 3 also can be arranged to other forms, for example at fixed contact 3, one end setting near conducting line row 2 turns edge, screw mounting hole is set on turning edge, and on conducting line row 2, corresponding screwed hole is set, thereby fixed contact 3 is fixed on conducting line row 2.In addition, the groove on fixed contact 3 is nonessential structure, can adopt other structures to replace, and for example, on conducting line row 2, counterbore is set, and line row screw 4 adopts sunk screw to be embedded in counterbore, and groove can save.In addition, above-described embodiment center line row's screw 4 and fixed contact screw 5 are only provided with one, in other embodiments of the invention, more than line row screw 4 and fixed contact screw 5 also can be arranged to two or three, can realize equally the fixing and be convenient to dismounting respectively of conducting line row and fixed contact.
