Description

TECHNICAL FIELD

[0001] The utility model relates to connector terminal technical field, concretely is a kind of multi-contact point connector terminal. BACKGROUND

[0002] Connector terminal is the key component of electrical signal transmission between electronic devices, and its design directly affects the stability and reliability of signal transmission. Most of the traditional connector terminals adopt single-point or double-point contact design, but these designs have exposed some obvious defects in practical application.

[0003] The connector terminal of single-point contact design, although simple in structure, is lower in manufacturing cost, but since there is only one contact point to undertake all current transmission tasks, it is easily affected by external environment. For example, in the vibration environment, single-point contact is prone to looseness, leading to poor contact, and further affecting the stable transmission of signals. In addition, the accumulation of dust and other pollutants may also cause single-point contact failure, further reducing the reliability of the connector.

[0004] Compared with single-point contact design, the connector terminal of double-point contact design has improved current distribution, but since the number of its contact points is limited, current is still prone to concentrate in local area, leading to the occurrence of local overheating. Local overheating not only may damage the connector terminal itself, but also may cause damage to the electronic devices connected thereto, and further affect the normal operation of the whole system. SUMMARY

[0005] In view of the deficiencies of the prior art, the utility model provides a kind of multi-contact point connector terminal, solves the problems raised in the above background art.

[0007] Base;

[0008] First elastic contact arm, first elastic contact arm is symmetrically connected to the upper portion of base;

[0010] First bending part and second bending part, the end of the first elastic contact arm and the second elastic contact arm extending away from each other is connected with first bending part and second bending part respectively;

[0011] First contact point and second contact point, the most protruding position of the first bending part and the second bending part is respectively set as first contact point and second contact point.

[0012] Further, the base is a hollow "N" shaped structure, and a pin is fixedly connected to a bottom end of the base.

[0013] Further, top ends of the two first elastic contact arms extend towards an end away from the base with a gradually close trend, and bottom ends of the two second elastic contact arms extend towards an end of the base with a gradually close trend.

[0014] Further, the connector terminal further comprises:

[0019] The connector terminal effectively solves the unstable connection problem of traditional single-point or double-point contact caused by factors such as vibration and dust through the innovative design of integrating four independent contact points by a single terminal. The core innovation point is the four-contact-point layout, which is designed in a double-row two-column symmetrical manner, significantly increases the contact area, effectively disperses the current load, and greatly reduces the contact resistance. This design not only improves the connection stability and reliability of the connector terminal, but also optimizes the current transmission efficiency and reduces the potential damage risk caused by local overheating, thereby providing a strong guarantee for the stable operation of electronic equipment.
