Detailed Description of the Embodiments
[0028] The invention will be further described in detail below in combination with embodiments with reference to the drawings.
[0029] Embodiment 1:

Fig. 1 shows a combined outgoing device, comprising the drawer inner copper bar (which is collectively called a first copper bar 1 below), the drawer outer copper bar (which is collectively called a second copper bar 2 below), a movable contact assembly 3 and a static contact assembly 4; and Fig. 2 is a use state diagram in which the outgoing device provided by the invention is mounted on sheet metal parts 28.
[0031] The structure of the movable contact assembly 3 is as shown in Fig. 1 and Fig. 2, and the movable contact assembly 3 comprises a contact box front inserting piece 5 and a contact box rear inserting piece 6.
[0032] The structure of the contact box front inserting piece 5 is as shown in Fig. 3 and Fig. 4, and the contact box front inserting piece 5 comprises a face plate part in the front and an inserting part at the rear, and in a use state, the inserting part is positioned on the rear side of the sheet metal part 28 after passing through a mounting hole in the sheet metal part 28, and the face plate part abuts against the front side of the sheet metal part. The inserting part is provided with a through groove which is through up and down and extends to the rear edge of the inserting part, a clamping groove 17 matched with the front end of a pre-opening device in shape and used for limiting the pre-opening device is disposed at the front end of the through groove, and inserting slots 23 as shown in Fig. 4 are also disposed at the rear of the face plate part of the contact box front inserting piece 5. First fixing holes 25 as shown in Fig. 4 are disposed in the lateral surface of the inserting part of the contact box front inserting piece 5.
[0033] The structure of the contact box rear inserting piece 6 is as shown in Fig. 5 and Fig. 6, !5 and the contact box rear inserting piece 6 comprises a face plate part in the front and an inserting part at the rear, eave-shaped inserting pieces 24 protruding forward, as shown in Fig. 5, are arranged at upper and lower positions of the face plate part, the eave-shaped inserting pieces 24 are adaptive to the inserting slots 23 on the contact box front inserting piece 5, concave grooves extending to the rear edge of the inserting part are oppositely disposed on the upper side and the lower side of the inserting part, and the upper and lower concave grooves cooperate with each other to form a chute 18 used for limiting the copper bar and allowing the copper bar to pass through. A guard plate 29 as shown in Fig. 6 can also be arranged at an inlet of the chute 18, so that the inlet of the chute 18 is in a rectangular shape adaptive to the shape of the copper bar; and the guard plate further defines the position of the copper bar so as to make the penetrating process of the copper bar stabler and more reliable. Second fixing holes 26 as shown in Fig. 6 are also disposed in the guard plate 29. The second fixing holes 26 correspond to the first fixing holes 25 of the contact box front inserting piece 5 in position. In the use state, the contact box rear inserting piece 6 sleeves the inserting part of the contact box front inserting piece 5, the face plate part of the contact box rear inserting piece 6 abuts against the rear side of the sheet metal part, the eave-shaped inserting pieces 24 are limited in the inserting slots 23, a fastener (e.g., a fixing pin) passes through the first fixing holes 25, the second fixing holes 26 and the copper bar to realize fixed connection of the contact box front inserting piece 5, the contact box rear inserting piece 6 and the copper bar.
[0034] The structure of the static contact assembly 4 is as shown in Fig. 1 and Fig. 2, and is similar with that of the movable contact assembly 3, and the static contact assembly 4 comprises a contact box front inserting piece 5 and a contact box rear inserting piece 6. The differences are that: (1) there is no need for the static contact assembly 4 tofix the pre-opening device, and thus, there is no need to dispose a clamping groove 17 for limiting the pre-opening device at the front end of a through groove of an inserting part of the contact box front inserting piece 5 of the static contact assembly 4; and (2) the static contact assembly 4 needs to be connected with a contact assembly 7, and thus, two sides of the through groove of the inserting part of the contact box front inserting piece 5 are also provided with third fixing holes 27 corresponding to each other up and down, and the third fixing holes 27 are matched with fixing pins 9 mutually to realize rotation limiting of the contact assembly 7, i.e., realize opening and closing motion of the contact assembly 7 by taking the fixing pins 9 as rotation center.
[0035] In order to reinforce the universality of the contact assembly, according to this embodiment, preferably, the movable contact assembly 3 and the static contact assembly 4 are set to be the same in structure, i.e., the inserting part of the contact box front inserting piece 5 in the movable contact assembly 3 is also provided with third fixing holes 27, and a clamping !5 groove 17 for limiting the pre-opening device is disposed at the front end of the through groove of the inserting part of the contact box front inserting piece 5 in the static contact assembly 4. Therefore, the contact box front inserting piece 5 and the contact box rear inserting piece 6 which are manufactured by only one set of dies can simultaneously adapt to structural demands of the movable contact assembly 3 and the static contact assembly 4, and can be selected according to actual demands.
[0036] As shown in Fig. 1 and Fig. 2, the movable contact assembly in the invention is used for fixation, connection and mounting of the first copper bar 1 and the pre-opening device; and the static contact assembly is used for fixation, connection and mounting of the second copper bar 2 and the contact assembly 7, wherein
[0037] the pre-opening device can be a pre-opening rib 10 shown in Fig. 7, preferably. The structure of the pre-opening rib 10 is as shown in Fig. 7, and the pre-opening rib 10 comprises a plurality of arc-shaped flaky protrusions in parallel to one another, and the number of the arc-shaped flaky protrusions is determined depending on the number of contacts included in the contact assembly 7. Bosses protruding outwards are respectively disposed at two ends of the pre-opening rib 10. When the pre-opening rib 10 is limited in the clamping groove 17, the bosses are hooked on the rear edge of the clamping groove 17 so as to take a further limiting effect on the position of the pre-opening rib 10. The pre-opening rib is a detachable structure so as to facilitate later maintenance.
[0038] It should be noted that in the invention, a contact mode between the contacts and the pre-opening device is not limited to the sliding contact mode illustrated in the embodiment above, and can also be one of other contact modes, as long as the objective of the invention can be achieved. For example, the contact can also realize insertion in a rolling friction mode. When a rolling inserting structure is adopted, the pre-opening device can be set as a rolling pre-opening device with a rolling part such as a ball or a roller; or a protrusion position of the contact can also be set as a rolling structure with a rolling part such as a ball or a roller. The rolling inserting structure enables the pre-opening device to be inserted in the contacts in a rolling friction mode, so that friction of an inserting part can be effectively reduced, and wear of the contacts is reduced, thereby prolonging the service life of the product.
[0039] The structure of the contact assembly 7 is as shown in Fig. 8, and the contact assembly 7 comprises at least one stage of contact 11; and various current class contact assemblies can be flexibly combined according to the magnitude of a current. Each contact 11 comprises two contact pieces 12 which are symmetrically arranged by taking a fixing pin 14 as the center so as to form a first open end for allowing the first copper bar 1 to be inserted therein at one end and a second open end for allowing the second copper bar 2 to be inserted therein at the other end, the !5 two contact pieces 3 of each contact implement openable and closable clamping by an elastic clamping device, and protrusions 15 disposed oppositely are arranged on the inner sides of the parts, close to the first open end, of the contact pieces 3 so as to form a pre-inserting opening 16 at the inserting end.
[0040] The structure of the elastic clamping device is as shown in Fig. 8, and each elastic clamping device comprises a fixing frame 19 and elastic pieces 20, first convex pillars 21 are arranged on the outer sides of the parts, close to the first open end, of the contact pieces 12, second convex pillars 22 are arranged on the outer sides of the parts, close to the second open end, of the contact pieces 12, and the elastic pieces 20 abut between the first convex pillars 21 and the second convex pillars 22 and are clamped by the fixing frame 19.
[0041] In order to enable the contact pieces to be effectively protected, in this embodiment, a contact shell 13 for sleeving each contact piece 12, as shown in Fig. 9, is also arranged. Each contact shell 13 sleeves the corresponding contact piece 12, fourth fixing holes 8 are disposed in the part of the side, close to the second open end, of the contact shells 13, and in the using process, the fixing pin 9 passes through the third fixing holes 27 in the inserting part of the contact box front inserting piece 5 and the fourth fixing holes 8, so that the contacts 11 can do the opening and closing motion by taking the fixing pin 9 as the rotation center. A plurality of stages of contacts 11 are overlaid and combined to form the contact assembly 7.
[0042] The working principle of the contacts is as shown in Fig. 10 and Fig. 11. The sizes of the pre-inserting openings 16 in the contacts 11 are smaller than the thicknesses of the corresponding arc-shaped flaky protrusions on the pre-opening rib 10 in the movable contact assembly 3, and movement of a switchgear body drives the movable contact assembly 3 to move towards a direction of the static contact assembly 4, or move towards a direction facing away from the static contact assembly 4. When the movable contact assembly 3 moves towards the direction of the static contact assembly 4 and before the contacts make contact with the first copper bar 1 of the movable contact assembly 3, the contact pieces 12 are separated towards two sides by the pre-opening rib 10 in the movable contact assembly 3, so that finally the contact pieces 12 and the first copper bar 1 are in friction-free contact.
