Description

Technical Field

[0001] The utility model relates to the technical field of elastic terminals, in particular to a stable double-contact elastic terminal. Background Art

[0002] An electronic connector, also often referred to as a circuit connector or electrical connector, refers to a conductor device that can bridge two conductors on a loop, enabling current or signals to flow from one conductor to another. An electronic connector is an electrical system that provides a separable interface to connect two sub-electrical systems. Simply put, a component used to complete the electrical connection between circuits or electronic devices, etc. is called a connector, that is, a bridge between the two. Such as: power plugs / sockets, IC sockets, telephone line plugs, etc. Electronic connectors usually achieve circuit connection by inserting and mating a female connector and a male connector, and the terminal plays a crucial role in this connection process.

[0003] Most of the current female connectors are single-contact connectors. The terminal in the female connector has a structure with one contact arm, and this one contact arm is conductively connected to the terminal in the male connector. Although this terminal structure can basically achieve the function of circuit conduction connection, after multiple insertions and extractions, due to the unreasonable design structure of the terminal, it is very easy to deform and cause failure. Moreover, with a structure having only one contact point, it is very easy to cause poor contact. Also, after long-term use, the terminal is prone to looseness, and it will swing or retreat during the insertion and extraction process, resulting in unstable circuit connection, poor product quality, inconvenience for users, and inability to meet the existing requirements. Therefore, it is necessary to study a new technical solution to improve the above problems. Summary of the Utility Model

[0004] In view of this, in view of the deficiencies existing in the prior art, the main purpose of the present utility model is to provide a stable double-contact elastic terminal, which can effectively solve the problems existing in the prior art that after multiple insertions and extractions of the connector, due to the unreasonable design structure of the terminal, it is very easy to deform and cause failure, a structure with only one contact point is very easy to cause poor contact, after long-term use, the terminal is prone to looseness, and it will swing or retreat during the insertion and extraction process, resulting in unstable circuit connection, poor product quality, and inconvenience for users.

[0008] As a preferred solution, the anti - withdrawal part includes a connecting part and two protrusions. The two ends of the connecting part are respectively connected to one end of the bending part and one end of the elastic contact arm. The two protrusions extend outward from both sides of the connecting part, effectively enhancing the stability of the connection structure between the terminal and external parts.

[0009] As a preferred solution, the protrusion is of a triangular structure, further enhancing the stability of the connection structure and improving the quality of the product.

[0010] As a preferred solution, the elastic contact arm includes a transverse arm body part, an inclined arm body part, and a contact elastic piece connected in sequence. The two transverse arm body parts are respectively connected to the corresponding anti - withdrawal parts, and the above - mentioned contact points are provided on the contact elastic piece.

[0011] As a preferred solution, a strengthening part is further provided. The strengthening part is arranged between the transverse arm body part and the inclined arm body part. The width of the strengthening part is greater than the widths of the transverse arm body part and the inclined arm body part. The setting of the strengthening part is beneficial to enhancing the clamping force of the elastic contact arm.
