Abstract
Disclosed is a connector lug for the connection of a locomotive high voltage electric appliance. The connector lug comprises a terminal and a fixed terminal connected with the terminal, wherein the fixed terminal is of an inverted-U shaped structure; and the internal empty width between the two side surfaces of the inverted-U shaped structure is matched to the width of the connecting busbar of the locomotive high voltage electric appliance. The structure of the utility model avoids the rotating looseness generated during the process of connecting the connector lug and the connecting busbar via a single hole, enlarges the contact area between the connector lug and the connecting busbar, and raises the current-carrying capacity of the connector lug.
Description
Technical field
The utility model relates to a kind of connector lug, particularly a kind of locomotive high-voltage electrical equipment connection connector lug.
Background technology
In order to satisfy the electric property requirement of locomotive high-voltage electrical equipment, adopt copper bus-bar and the larger copper core cable wiring of cable diameter at the locomotive high-voltage appliance chamber more.Because conducting electricity very well of copper, the two ends of connection cable are connected with the binding post of each High-Voltage Electrical Appliances after adopting the copper connector lug to carry out crimping.The existing copper connector lug of DCT type that adopts comprises terminals and stiff end, and stiff end is a copper coin that a bolt hole is only arranged.Because the High-Voltage Electrical Appliances outlet terminal in the locomotive screen cabinet is placed on bottom of cabinet bulk more, the amount of deflection of connection cable is larger simultaneously, under the effect of locomotive vibration and long-term flexible power, connector lug can rotate inclination, cause the contact area of connector lug to reduce, can not satisfy the electric property requirements such as cable ampacity, therefore need a kind of Novel connecting the end of a thread to improve the stability of High-Voltage Electrical Appliances cable wiring, increase the contact area that connects, satisfy the electric property requirements such as ampacity.
Summary of the invention
Technical problem to be solved in the utility model is for the prior art deficiency, to provide a kind of locomotive high-voltage electrical equipment to connect and use connector lug, raising connector lug and the contact area that is connected busbar, thereby the ampacity of raising connector lug.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of locomotive high-voltage electrical equipment connects uses connector lug, comprise terminals and the stiff end that is connected with terminals, described stiff end is an inverted U-shaped, and the inner space width between two sides of described inverted U-shaped is connected busbar width coupling with locomotive high-voltage electrical equipment.
As preferred version, have two fixing holes on the bottom surface of described inverted U-shaped.
As preferred version, the inner space width between two sides of described inverted U-shaped connects the narrow 0.5mm of width of busbar than locomotive high-voltage electrical equipment.
Compared with prior art, the beneficial effect that the utility model has is: the utility model is designed to inverted U-shaped with the stiff end of connector lug, and the width that makes two sides of inverted U-shaped slightly is narrower than connection busbar width, thereby guarantee when stiff end is connected with busbar, stiff end has three contact-making surface close contacts with being connected between busbar, like this, both avoided connector lug and to be connected the rotation that produces when single hole connects between busbar loosening, strengthen again connector lug and the contact area that is connected busbar, improved the ampacity of connector lug; Secondly, stiff end adopts double-pore structure, compares existing single hole structure, has improved the bonding strength of connector lug and busbar.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
Embodiment
As shown in Figure 1, the utility model one embodiment comprises copper terminals 1 and the copper stiff end 2 that is connected with terminals 1, described stiff end 2 is an inverted U-shaped, and the inner space width between two sides 5 of described inverted U-shaped is connected busbar width coupling with locomotive high-voltage electrical equipment; Have two fixing holes 3 on the bottom surface 4 of described inverted U-shaped.
Inner space width between two sides of described inverted U-shaped connects the width slightly narrow (about narrow 0.5mm) of busbar than locomotive high-voltage electrical equipment, guaranteed when connector lug is connected with busbar, and connector lug has three contact-making surface close contacts with being connected between busbar; Adopt diplopore connector lug structure to replace single hole connector lug structure, improve the bonding strength of connector lug and busbar, structure of the present utility model had both avoided connector lug and to be connected the rotation that produces when single hole connects between busbar loosening, strengthen again connector lug and the contact area that is connected busbar, improved the ampacity of connector lug.
The utility model connector lug adopts the pressing process similar to having the DCT connector lug now, at first, get the copper pipe of suitable length, adopt DCT connector lug pressing mode to make connector lug, difference is that stiff end is pressed into inverted U-shaped, then stamps out two bolt connecting holes in the bottom surface of inverted U-shaped.
Claims (3)
1. a locomotive high-voltage electrical equipment connects and uses connector lug, comprise terminals and the stiff end that is connected with terminals, it is characterized in that, described stiff end is an inverted U-shaped, and the inner space width between two sides of described inverted U-shaped is connected busbar width coupling with locomotive high-voltage electrical equipment.
2. connector lug is used in locomotive high-voltage electrical equipment connection according to claim 1, it is characterized in that, has two fixing holes on the bottom surface of described inverted U-shaped.
