Description
Technical field
The utility model relates to a kind of calibrating terminal.
Background technology
Fig. 1 to Fig. 6 has shown a kind of structure of the traditional calibrating terminal that is used to be electrically connected, and wherein Fig. 1 is the perspective view of traditional test terminal; The perspective view that Fig. 2 is a traditional test terminal shown in Figure 1 when another angle is observed; Fig. 3 is the perspective view of female plug seat in Fig. 1 traditional test terminal; The perspective view that Fig. 4 is a female plug seat shown in Figure 3 when another angle is observed; Fig. 5 is the perspective view of public plug in Fig. 1 traditional test terminal; The perspective view that Fig. 6 is a public plug shown in Figure 5 when another angle is observed.See Fig. 1 to Fig. 6, this kind traditional test terminal comprises public plug (1) and female plug seat (2); Described public plug (1) comprises substrate (11), be fixed on four inserting columns (12) of substrate one side and be fixed on six binding posts (13) of another side of substrate; Each inserting column (12) comprises the insulated column (121) that is fixed on the substrate (11) and is fixed on insulated column (121) two current-carrying plates insulated from each other (122) of two side ends up and down that each current-carrying plate (122) is electrically connected with a binding post (13); Described female plug seat (2) comprises jack body (21) and fixed connecting plate (22); Described jack body (21) comprises four terminal box (4), a plate washer that is arranged side by side with terminal box (5), a grafting panel (6) and fixed connecting plates (22) that are provided with four spliced eyes (211) of being provided with slot; One side of each terminal box (4) is provided with two connection terminals (3) up and down, and another side is provided with socket (41); Described fixed connecting plate (22) is provided with keeper (222) and fixedlys connected with a side that is provided with connection terminal (3) of jack body (21) by keeper (222); Described grafting panel (6) is fixed on a side that is provided with socket (41) of terminal box (4), and the spliced eye (211) on the grafting panel (6) is corresponding with socket (41) position of terminal box (4).Described four terminal boxes (4) and a plate washer (5) head and the tail are concatenated into a row successively and adopt nut assembly (7) to be fixed and link together; The quantity of the terminal box in this kind calibrating terminal (4) can be determined according to actual needs, for example three-phase circuit can select for use three or four terminal boxes to make calibrating terminal, single-phase circuit can select for use one or two terminal box to make calibrating terminal, but the quantity of terminal box (4) is identical with the quantity of inserting column (12) in the public plug (1), and the quantity of described connection terminal (3) is identical with the quantity of binding post (13) in the public plug.Because the side near grafting panel (6) of each terminal box (4) and plate washer (5) can be provided with the open-work that matches with nut (7), with a plurality of terminal boxes (4) and plate washer (5) head and the tail serial connection successively fixedly the time, the nut assembly (7) that the open-work of each terminal box (4) and plate washer (5) is passed in use is fixed and clamped each terminal box (4); And terminal box (4) and plate washer (5) are limited owing to the space at a side that is provided with splicing ear (3), can not adopt nut assembly (7) to pass each terminal box (4) again is fixed, so just adopt a fixed connecting plate (22) to be fixed on terminal box (4) and the plate washer (5) by interference fit, thereby each terminal box (4) and plate washer (5) be fixedly clamped to be coupled together, and strengthens between each terminal box (4) and the steadiness that line box (4) is connected with plate washer (5) and the reliability of use.
This kind calibrating terminal in use, at first each connection terminal with the female plug seat is electrically connected with extraneous electric wire, simultaneously two binding posts that need conducting to test on the public plug are electrically connected, the spliced eye that makes each inserting column of public plug pass the grafting panel of female plug seat then inserts in each terminal box, each connection terminal is electrically connected with a current-carrying plate on the inserting column that inserts this terminal box by the conductor that is arranged in the terminal box, thereby each connection terminal all with a public plug on binding post realized being electrically connected, so just can test the circuit between each predetermined connection terminal.
The shortcoming of this kind calibrating terminal is: (1) is not in order to influence the normal wiring of connection terminal, the fixed connecting plate of this kind calibrating terminal is between two connection terminals up and down of each terminal box, outside two connection terminals are exposed to up and down, the effect of described fixed connecting plate only is each terminal box and the plate washer of being fixedly clamped, because it is connection terminal is exposed outside, thereby cause a series of drawback, for example operating personnel touch exposed connection terminal easily and cause electric shock accidents, terminal screw on the connection terminal is lost because of dropping easily, and connection terminal suffers to collide with external object and damage or the like easily.(2) this kind calibrating terminal is when having plural terminal box, on the public plug also with regard to the corresponding binding post that has more than four, thereby will have two or more electric connection mode between the binding post; The public plug of this kind calibrating terminal is then owing to being symmetrical arranged of self exists two kinds of inserting mode, directly can insert, also can insert behind the Rotate 180 degree, be positioned at the leftmost connection-peg of public plug with one, can be inserted in the terminal box of female plug seat left-hand end, also can be inserted in the terminal box of female plug seat right-hand end; But for certain concrete test, exist relation one to one between each binding post and each connection terminal, the terminal box that also is inserting column on the public plug and female plug seat exists relation one to one, and each inserting column must be inserted in the specific terminal box, can not wrong plug; And this kind calibrating terminal is not made sign one to one to the terminal box of inserting column and female plug seat, so the traditional test terminal in actual use, owing to need repeatedly plug, and interval time may be longer, often misplug and connect, promptly inserting column is not inserted in the specific terminal box mishap that causes personnel to get an electric shock or burn electric product yet.
