Embodiment Construction

[0015] Examples of high current jack contacts, such as Figure 1-4 As shown, the high-current socket contact includes a socket rear sleeve 11 and a core sleeve 12 assembled in the socket rear sleeve 11 .

[0016] Except for the front port structure of the jack rear cover 11, other structures are all prior art, therefore, only the front port position of the jack rear cover 11 is introduced in detail here. The main difference from the prior art is that the front port of the socket rear sleeve 11 in this embodiment is provided with an enlarged diameter structure, which makes the front part of the inner hole of the socket rear sleeve 11 form a large front and a small rear. step hole.

[0017] The core sleeve 12 is the main part used to cooperate with the adapter pin. In this embodiment, the core sleeve 12 specifically adopts a torsion spring, which is curled in the socket rear sleeve 11 along the circumferential direction of the socket rear sleeve. A cylindrical structure connec...

Abstract

The invention relates to the field of an electric connector, in particular to a high-current jack contact. The high-current jack contact comprises a jack rear sleeve and a core sleeve assembled in the jack rear sleeve, wherein the core sleeve is a crown belt or a torsional spring; a cylindrical structure which is connected end to end is formed by the core sleeve in the jack rear sleeve along the circumferential direction of the jack rear sleeve; the core sleeve is in interference fit with the jack rear sleeve. Due to the fact that when the high-current jack contact is matched with an adaptive contact pin, the high-current jack contact does not leave a space for the deflection of the contact pin, so the reliability of matching with the contact pin can be greatly improved; furthermore, due to the fact that the core sleeve is in interference fit with the jack rear sleeve, the pressure between the core sleeve and the jack rear sleeve can be greatly increased, and the whole resistance of the contact is reduced. In conclusion, according to the high-current jack contact provided by the invention, the problem that the existing contact used for transmitting high current is not reliably in contact with the adaptive contact pin and is high in resistance is solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a large-current jack contact. Background technique [0002] With the continuous expansion of the application field of electrical connectors, electrical connectors are also used in some high-power occasions that need to transmit large currents to realize the connection and disconnection of electrical circuits. This has prompted the generation of high-current electrical connectors. As the main component of power transmission, the contact piece is undoubtedly the most important component of the high-current electrical connector. It can be said that the transmission capacity of the contact piece directly determines the transmission power of the electrical connector. [0003] At present, the jack contacts commonly used in high-current electrical connectors include crown strip jacks and torsion spring jacks. Both the crown band socket and the torsion spring socket are composed o...
