Abstract
The invention provides a connection structure for a battery box connector. The connection structure comprises an insulating shell, a metal insert and a binding post, wherein the metal insert is in a shape of a right prism with a through hole between two bottom faces, the through hole is partially round and partially hexagonal; the binding post is provided with a hexagonal prism portion in the middle, and an annular clamping slot is arranged between a binding end of the binding post and the hexagonal prism portion; and the metal insert is inserted into the insulating shell, the binding post is inserted into the through hole of the metal insert, and the hexagonal prism portion of the binding post is matched with the hexagonal hole of the metal insert. The connection structure is high in torque bearing capacity and especially applicable to battery box connectors of automobile charging stations.
Description
Technical field
The present invention relates to field of connectors, be specifically related to the battery case connector that a kind of automobile fills electrical changing station.
Background technology
Along with popularizing of electric automobile, the construction of electric vehicle charging electrical changing station is also progressively launching.In filling electrical changing station, use the battery case connector, need to bear large current load, adopt than high pulling torque to guarantee the wire compacting on the binding post of battery case connector when therefore requiring wiring.For example the EV-BC750V/400A high current connector when carrying out wiring, requires moment of torsion to reach 35Nm.But the insulation shell of connector is generally working of plastics, when the high pulling torque on the binding post is passed to insulation shell, and the damages such as the easy cracking in position that insulation shell is connected with binding post.For preventing the generation of this problem, generally be that terminals at binding post process external screw thread, by two nut check wires, when wiring, need a hand tool using to clamp lower square nut, the another hand is locked upper square nut, avoids moment of torsion to pass to binding post, operating difficulties, and uncontrollable wire trend.
Summary of the invention
The purpose of this invention is to provide a kind of syndeton, the battery case connector that makes automobile fill electrical changing station can bear high pulling torque.
For achieving the above object, embodiments of the invention provide following technical scheme:
Be used for the syndeton of battery case connector, comprise:
Insulation shell;
Metal insert, it is the vertical prismatic shape that has through hole between two bottom surfaces, and described throughhole portions is circular hole, and part is hexagonal hole;
Binding post, its middle part has the hexagon part, and has annular slot between its terminals and described hexagon part;
Described metal insert embeds described insulation shell, and described binding post inserts the through hole of described metal insert, and the hexagon part of described binding post cooperates with the hexagonal hole of described metal insert.
Preferably, the side of described metal insert has annular groove.
Preferably, the terminals of described binding post have internal thread.
Owing to embed metal insert in insulation shell, and metal insert is vertical prismatic shape, so insulation shell can bear larger moment of torsion, when wiring, moment of torsion on the binding post partly passes to metal insert by the hexagon of binding post, passes to insulation shell again, has avoided the housing damage.By the annular slot on the binding post, can realize the location of binding post and metal insert, insulation shell.
Further, the side of metal insert has annular groove, and metal insert is entrenched in the insulation shell better, avoids inserts to come off.
Further, process internal thread at the terminals of binding post, can adopt bolt to compress wire, save the space.
Description of drawings
Next in connection with accompanying drawing embodiments of the invention are described in further detail, wherein:
Fig. 1 is the stereogram of the metal insert of embodiments of the invention;
Fig. 2 is the stereogram of the binding post of embodiments of the invention;
Fig. 3 is the assembling schematic diagram of embodiments of the invention.
Embodiment
Fig. 1 shows the structure of metal insert 10.Metal insert 10 is vertical prismatic shape, and in the present embodiment, right prism is eight prisms, and those of ordinary skills can imagine that it can also be the shapes such as six prisms, pentagonal prism.Between two bottom surfaces of metal insert 10, have through hole.The part of through hole is circular hole 11, and a part is hexagonal hole 12.In the side of metal insert 10, has annular groove 13.
Fig. 2 shows the structure of binding post 20.The terminals 21 of binding post 20 have internal thread, and the middle part has hexagon part 22.Between terminals 21 and hexagon part 22, process annular slot 23 on the outer surface of binding post 20.
Fig. 3 has shown insulation shell 30, metal insert 10 and binding post 20 are how to be assembled together the syndeton that forms the battery case connector.For clear, in Fig. 3, insulation shell 30 schematically shows with dotted line.Insulation shell 30 is generally by the plastics manufacturing, by mode moulding such as injection, mold pressings.Metal insert 10 is embedded in the insulation shell 30.Owing to have annular groove 13 on the side of metal insert 30, so that metal insert 30 is chimeric more firm, be not easy to come off.The terminals 21 of binding post 20 pass hexagonal hole 12 and the circular hole 11 of metal insert 10, stretch out insulation shell 30.The hexagon part 22 of binding post 20 cooperates with the hexagonal hole 12 of metal insert.Mounting spring collar 50 on annular slot 23, and can between the end face of spring collar and insulation shell 30, increase as required plain cushion 40, thus binding post 20 is fixed in the metal insert 10.During wiring, the binding post of wire is enclosed within on the bolt 60, then bolt 60 is screwed in the internal thread of the terminals 21 of binding posts 20.This moment, operating personnel can the tight bolt of hand-screw, and the another hand keeps wire trend, easy-to-connect.When swivel bolt 60 compressed wire, moment of torsion can pass to metal insert 10 by six prismatic parts 22 of binding post 20, and then passes to insulation shell 30 by metal insert 10.Because the existence of metal insert 10 even adopted larger moment of torsion, can guarantee that still insulation shell 30 is not easy to be damaged.Those of ordinary skills can imagine at an easy rate that terminals 21 also can have external screw thread, and only can compress wire with a nut this moment, no longer need double nut locking.But adopt nut check compacting wire, need to be at the insulation shell 30 outside terminals 21 of growing of reserving, and employing bolt-locking compacting wire, can make bolt enter binding post 20 inside, need to not stay in insulation shell 30 outsides long terminals 21, save the space, so terminals 21 process internal thread and have more advantage.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and only being subjected to the restriction of claim, those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present invention and scope.
