Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a single snap-fit ​​current terminal and connector. Background Technology

[0002] Automotive connectors are used to achieve electrical connections or signal transmission. Their working principle involves the combination of a plastic socket sheath and metal socket terminals, which are then inserted into a plastic plug sheath and metal plug terminals to establish a circuit connection. The main components for this circuit connection are the plug and socket terminals, while the socket and plug sheaths serve to secure and protect them. Currently, in automotive connectors, to improve terminal stability, symmetrical mounting brackets are typically added to both sides of the terminal. While these brackets prevent detachment, they reduce the amount of material used in the terminal, thus lowering its current overload capacity. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a single snap-fit ​​current terminal and connector.

[0004] At least one embodiment of this utility model provides a single-clamp current terminal, including an integrally formed contact end and a riveting end. The contact end includes two symmetrically arranged contact pieces, and a connecting part is provided between the two contact pieces. A contact spring is connected to the side of the connecting part near the end of the contact end. When the male end is inserted, the contact spring increases the insertion force and ensures the contact stability of the terminal. An anti-disengagement buckle is connected to the side of the connecting part away from the end of the contact end. The terminal is designed with a single-clamp structure, which effectively reduces material consumption and can increase the current overload capacity.

[0005] In one embodiment of the present invention, the inner wall of the contact piece is provided with a protrusion, which provides sufficient insertion force when the male end is inserted, thus helping to ensure the contact stability of the terminal.

[0006] In a single-clamp current terminal provided in one embodiment of the present invention, a limiting post is provided between the contact end and the rivet end, and the terminal can be easily positioned and installed by means of the limiting post when inserted.

[0007] In one embodiment of the present invention, the single snap-fit ​​current terminal includes a first crimping piece and a second crimping piece for crimping the cable, thereby improving the crimping strength and preventing the cable from loosening.

[0008] The connector provided in at least one embodiment of this utility model includes a housing and a plurality of current terminals inserted into the housing, wherein the current terminals are the aforementioned single-clamp type current terminals. The housing has a current terminal insertion portion, which has current terminal holes for inserting the current terminals. The contact end of the current terminal is inserted into the current terminal hole and secured by an anti-disengagement snap. The riveted end of the current terminal is connected to a current cable for transmitting current.

[0009] The connector provided in at least one embodiment of this utility model has a signal terminal insertion part on the housing, a signal terminal hole in the signal terminal insertion part, a signal terminal inserted into the signal terminal hole, and a signal cable connected to the tail end of the signal terminal for transmitting signals.

[0010] In a connector provided in one embodiment of the present invention, the inner wall of the current terminal hole is provided with protrusions, which abut against the sides of the two contact pieces of the current terminal to prevent the ends of the two contact pieces from over-expanding after repeated insertion and removal of the male terminal, thereby ensuring the contact stability between the two contact pieces and the male terminal.

[0011] In a connector provided in one embodiment of the present invention, the inner wall of the current terminal hole is provided with a clearance groove, which corresponds to the contact spring of the current terminal. The clearance groove provides space for the deformation of the contact spring when the male end is inserted.

[0012] In one embodiment of the connector provided by this utility model, a wire clamp is further included, and a plurality of wire grooves are arranged side by side on the upper and lower sides of the wire clamp. The wire grooves correspond one-to-one with the current cables, which helps to keep the current cables as a whole stable. The two ends of the wire clamp are provided with wire clamp buckles that engage with the housing.

[0013] In a connector provided in one embodiment of the present invention, the color of the surface of the current terminal plug 2 is different from the color of the surface of the housing 1. When the current terminal plug 2 is inserted, if the color of the surface of the current terminal plug 2 is not visible from the outside, it indicates that the connector has been fully inserted. If it is not fully inserted, the color of the current terminal plug 2 will be visible. The different colors of the current terminal plug 2 and the housing 1 make it easy to distinguish them and can limit the insertion and removal of the connector.

[0014] In one embodiment of the connector provided by this utility model, the surface of the housing is provided with a hook, and the hook provides a fastening force to ensure the connection stability of the connector.

[0015] The beneficial effects of this utility model are as follows: The single-clamp current terminal provided by this utility model increases the insertion force through the contact spring when the male end is inserted, ensuring the contact stability of the terminal. An anti-dislodgement buckle is connected on the side of the connection part away from the contact end. The terminal is designed with a single-clamp structure, which effectively reduces material feeding and can increase the current overload capacity. In addition, the single-clamp design also has a foolproof function. Compared with the existing symmetrical hanging platform design, it is easier to identify whether it is installed backwards during insertion. Attached Figure Description
