Embodiment
As shown in Figure 1, it is the structural representation of the terminal assemblies 10 of the utility model one embodiment.Terminal assemblies 10 comprises: binding post 100, line ball screw 200 and contact 300.
The protuberance 120 that binding post 100 comprises terminal body 110 and is connected with terminal body 110.Terminal body 100 is the quadrangle tubular structure of both ends open, offers screw 112 in terminal body 110.Line ball screw 200 wears screw 112.
Please refer to Fig. 2, it is the front view of the binding post 100 shown in Fig. 1.Terminal body 110 comprises screw 112 tops, place 111, two sidewalls 113 adjacent with described top 111, and the bottom 114 relative with described top 111.Two sidewalls 113 be arranged in parallel, and sidewall 113 bends inwards and forms inclined-plane 115 away from the end position at top 111.Inclined-plane 115 tilts to the direction near line ball screw 200, and connects into obtuse angle with bottom 114.In the present embodiment, the number of degrees at obtuse angle are 98～100 degree.The diameter of the conventional wire of general family is 1.38mm, 1.78mm or 2.25mm, when the number of degrees at obtuse angle are 98～100 while spending, can ensure that terminal assemblies 10 is in the time of locking wire, prevent two Slideslips of wire to line ball screw 200 end faces, even move in the gap between line ball screw 200 and binding post 100 madial walls along the screw thread of line ball screw 200.Can ensure that again wire can be pressed on the bottom 114 of terminal body 110 simultaneously.Certainly, the number of degrees at obtuse angle can be also other number of degrees, can lock the wire of different-diameter to meet terminal assemblies 10.
As shown in Figure 3, it is the decomposition texture schematic diagram of the terminal assemblies 10 shown in Fig. 1.Terminal body 110 also comprises by the top 111 of terminal body 110 extends and bends the buckle 116 to form to a side, on the sidewall 113 of terminal body 110, offers draw-in groove 117, and buckle 116 engages with draw-in groove 117.Concrete, the dual-side of buckle 116 all offers chamfering 118, and chamfering 118 supports with the sidewall of draw-in groove 117, to prevent that buckle 116 from skidding off in draw-in groove 117, thereby makes binding post 100 more firm in combination.
Protuberance 120 is connected with the top 111 that offers screw 112 in terminal body 110, offers installing hole 121 on protuberance 120.In other embodiments, protuberance 120 also can be connected with the sidewall of terminal body 110 113 or bottom 114.Contact 300 is arranged in installing hole 121, and the contact-making surface of contact 300 is positioned at the outside of binding post 100.In the present embodiment, contact 300 is silver contact.In other embodiment, contact 300 can be also copper contact.
As shown in Figure 4, it is the cut-away view of the binding post 100 shown in Fig. 2 along A-A line.Binding post 100 comprises the first bronze medal layer 400, steel layer 500 and the second bronze medal layer 600 of laminating successively.The first bronze medal layer 400 is positioned at the inner side of binding post 100, and the second bronze medal layer 600 is positioned at the outside of binding post 100, and steel layer 500 is between the first bronze medal layer 400 and the second bronze medal layer 600.Be appreciated that binding post 100 is by being respectively equipped with the first bronze medal layer 400 and the second bronze medal layer 600 in the inside and outside both sides of steel layer 500.On the one hand, steel layer 500 can ensure that binding post 100 can meet the hardness standard of GB.On the other hand, the first bronze medal layer 400, steel layer 500 and the second bronze medal layer 600 coordinate, and can improve the electrical conductivity of binding post 100 entirety, to meet the conduction standard of GB.It is pointed out that the first bronze medal layer 400 of working as coordinates with steel layer 500, the hardness standard that can meet GB is during with conduction standard, and the second bronze medal layer 600 can omit.Binding post 100 is by being provided with the first bronze medal layer 400 in the inner side supporting with electric wire, and is provided with steel layer 500 in the outside of the first bronze medal layer 400, meets hardness standard and the conduction standard of GB, and contact can be directly installed on binding post 100.Relatively traditional binding post, need to increase a conducting strip made of copper, then contact is installed on conducting strip.The structure of binding post 100 is simpler.
The process that terminal assemblies 10 is locked wire is as follows:
As shown in Figure 4, it is the fundamental diagram of the terminal assemblies 10 shown in Fig. 1.First wire is positioned over to the bottom 114 of terminal body 110, then line ball screw 200 is rotated to line ball screw 200 to close guidewire movement through screw 112 continuation, until wire is under the extruding of line ball screw 200, be close to the bottom 114 of terminal body 110, realize binding post 100 and lock the function of wire.
Two sidewalls 113 of terminal body 110 have away from top 111 end positions bend inwards form inclined-plane 115.Inclined-plane 115 tilts to the direction near line ball screw 200, and connects into obtuse angle with bottom 114.The diameter of the conventional wire of general family is 1.38mm, 1.78mm or 2.25mm, line ball screw 200 is 0.2～0.3mm to the vertical range of sidewall 113, this can prevent that wire is pressed in the gap between line ball screw 200 and sidewall 113 in line ball screw 200 rotary courses, makes wire can move to the rotation of line ball screw 200 bottom 114 along inclined-plane 115 and then be locked.Line ball screw 200 is 0.1mm to inclined-plane 115 with the vertical range of the junction of bottom 114, by leave the tolerance of 0.1mm between line ball screw 200 and inclined-plane 115 and the junction of bottom 114, to improve the suitability of line ball screw 200 and binding post 100.
In the wiring space that the end face that above-mentioned terminal assemblies 10 not only can make wire be locked at securely bottom 114, inclined-plane 115 and line ball screw 200 surrounds, in gap between line ball screw 200 and sidewall 113, push sidewall 113 and bloat to side but also can prevent that wire is pressed in line ball screw 200 rotary courses, and then prevent that terminal assemblies 10 is out of shape.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
