Abstract
Description
Technical Field
[0001] The utility model relates to the field of new energy high-voltage connectors, in particular to a jack-type short-circuit terminal for a connector. Background Art
[0002] With the continuous development of electric vehicles, more and more technicians and users are paying more and more attention to the high-voltage safety issues of electric vehicles, especially the increasing application of higher platform voltages (800V and above). As a measure to ensure the high-voltage safety of electric vehicles, the high-voltage interlock (HVIL) function is becoming increasingly important, and the stability and response speed of the HVIL function are constantly being improved.
[0003] Most of the existing high-voltage interlocking structures use two separate socket terminals in a rectangular shape. The plug uses a rectangular short-circuit pin to connect the interlocking circuit. Some connector sockets use two pin terminals, but the plug uses a single-sided overlapping spring clip to achieve short-circuit connection. The vibration resistance of rectangular pins and sockets is poor. Faced with the increasingly stringent vibration requirements of vehicles, there is a risk of momentary vibration interruption. In addition, the use of rectangular short-circuit pins in the plug may cause the short-circuit pins to be accidentally touched when the customer is wiring, resulting in the pins being crooked and unable to be plugged in. Although the single-sided overlapping spring clip can effectively avoid misoperation during the wiring process, the vibration resistance is limited because the pins and sockets are only in contact on one side. Utility Model Content
[0004] In order to overcome the shortcomings of the existing short-circuit terminal, such as easy breakage and poor vibration resistance, the utility model provides a short-circuit terminal in the form of a socket for a connector.
[0005] The technical solution adopted by the utility model to solve the technical problem is: a jack-type short-circuit terminal for a connector, comprising a connecting plate, a curled circle, and an arched spring piece. Curled circles are respectively provided at both ends of the connecting plate, and grooves for inserting pins are provided in the curled circles. Arched spring pieces for contacting the pins are provided on the curled circles.
[0006] According to another embodiment of the present invention, two mutually symmetrical arched spring pieces are respectively provided on the upper and lower sides of the curled circle, and the raised portion of the arched spring piece is located in the through groove of the insertion pin.
[0007] According to another embodiment of the present invention, the connecting plate is further provided with a spring sheet for fixing the connecting plate in the housing.
[0008] The beneficial effect of the present invention is that the utility model adopts a jack-type short-circuit terminal. Since the jack terminal can be completely wrapped in a plastic shell, it can effectively avoid accidental contact during the wiring process of the plug. The jack-type short-circuit terminal has a rolled structure and contacts the socket pin through the arched spring pieces on both sides, which can improve the vibration resistance after the pinhole contact.

[0013] Figure 1 It is a structural diagram of the utility model; Figure 2 It is a structural schematic diagram of the utility model for inserting a pin into a curled circle.
[0014] Combined with attachment Figure 1 and attached Figure 2 As shown, a short-circuit terminal in the form of a socket for a connector includes a connecting plate 1, a curled circle 2, and an arched spring piece 3. Curled circles 2 are provided at both ends of the connecting plate 1, and a groove for inserting a pin 4 is provided in the curled circle 2. An arched spring piece 3 for contacting the pin 4 is provided on the curled circle 2.
[0015] Two mutually symmetrical arched spring pieces 3 are respectively provided on the upper and lower sides of the curled circle 2 , and the raised portions of the arched spring pieces 3 are located in the grooves of the insertion pins 4 .
[0016] The connecting plate 1 is provided with a spring piece 5 for fixing the connecting plate 1 in the housing.
[0017] The two coils 2 can be embedded in the mounting holes of the plastic housing, thus preventing the short-circuit terminal from being exposed and easily bent or broken, thus preventing it from connecting with the pin 4. When the two coils 2 of the disconnect terminal are respectively embedded in the two mounting holes of the plastic housing, the connecting plate 1 is embedded in the plate mounting groove of the plastic housing, and the spring 5 can secure the short-circuit terminal in the plastic housing through elasticity.
[0018] When the pin 4 is inserted into the groove of the coil 2, the upper and lower arched springs 3 clamp the pin 4, thereby connecting the pin to the short-circuit terminal. The clamping of the two arched springs 3 improves the vibration resistance of the short-circuit terminal after contact with the pin 4.
