Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a converter casing, which comprises a housin 1, casing 1 is including fixing the wire guide 2 that is close to wiring hole department on casing 1, and have a plurality of wire channels 201 that are used for the electric wire location on the wire guide 2, fixedly connected with is used for the fixed subassembly of electric wire that the electric wire is fixed on casing 1, the fixed subassembly of electric wire is including fixing reference column 5 in casing 1 both sides, sliding connection has pressure strip 6 on two reference columns 5, fixedly connected with runs through the screw rod 7 at pressure strip 6 middle part on the wire guide 2, the outside of screw rod 7 closes soon through the screw thread and is connected with the nut 8 that extrudees pressure strip 6 and compress tightly the electric wire to wire channel 201 direction.
The inboard electric property of the wiring hole of casing 1 will be inserted and lay in the metallic channel 201 of metallic plate 2 inboard, separate to many electric wires through a plurality of metallic channels 201 and lay, rotate nut 8 for nut 8 moves along the screw thread of screw rod 7, thereby extrudees pressure strip 6 and extrudees towards the electric wire direction along reference column 5, accomplishes compressing tightly fixedly to the electric wire from this.
Specifically, as shown in fig. 2 to 4, the electric wire fixing assembly further includes a support frame 4 fixed on the housing 1, a plurality of sliding columns 12 sliding connected through the support frame 4 on the support frame 4 are connected with pressing rollers 14 respectively elastically extruding towards a plurality of wire grooves 201, an extruding spring 13 is sleeved between the support frame 4 and the pressing rollers 14 outside the sliding columns 12, an inner groove distributed annularly is formed in the periphery of the pressing rollers 14, a circular through groove is formed between the pressing rollers 14 and the wire grooves 201, two support columns 9 are fixedly connected between the pressing plate 6 and the support frame 4 on the wire guide plate 2, a transmission rod 3 used for extruding an electric wire outwards is fixedly connected on the two support columns 9, a baffle 10 used for limiting the transmission rod 3 in a sliding manner is fixedly connected to the free end of the support column 9, a reset spring 11 is sleeved between the transmission rod 3 and the wire guide plate 2 outside the support column 9, and the transmission rod 3 is in a cylindrical structure with the butt joint of the electric wire.
