Embodiment Construction

[0050] It should be noted that the features in the embodiments and embodiments in the present application may be combined with each other in the case of an unable conflict. The present invention will be described in detail below with reference to the drawings.

[0051] Ring having one kind of terminal memory, the memory includes a terminal body 1 and the ring 2, comprising a terminal body contact section 13, contact section 13 is provided inside radial dimension changing plug cavity, two sets of the memory ring 13 disposed on an outer contact section and contact with the contact section 13, the memory ring 2 made of shape memory alloy, the memory ring section 13 of the contact 2 can be contracted, such as Figure 1 to 4 Indicated.

[0052] The presence of the memory ring transformation temperature, contact section 13 generally radially expanded state, when the temperature of the memory ring 2 is less than the transformation temperature, the memory ring 2 will radially expand the ex...

Abstract

The invention provides a terminal with a memory ring. The terminal comprises a terminal body (1) and the memory ring (2); the terminal body (1) comprises a contact section (13); the memory ring (2) is sleeved outside the contact section (13); the memory ring (2) is contacted with the contact section (13); the memory ring (2) is made of memory alloy; and the memory ring (2) can make the contact section (13) contract. The terminal with the memory ring can realize butt joint without insertion force; the contact area and the contact force of the terminal and the matched terminal are ensured through temperature rise during working, so that the contact reliability is improved; and due to the fact that the requirement for the insertion force is omitted, the working is easier, and the working efficiency is improved.

Description

Technical field [0001] The present invention relates to one kind of terminal with memory loop. Background technique [0002] With the increasing popularity of electric vehicles, the demand for charging plug and charging cradle are gradually increasing. In the prior art, the charging plug, charging post, and a terminal on the charging stand automobiles rely shrapnel, bolt tightening, and to realize with the terminal contact mechanical structure, etc., it requires a certain insertion force, the tool to complete the installation. Further, the terminal will work in the process as a result of increased temperature resistance increases, and the current decreases. Inventive content [0003] In order to improve the efficiency of mating terminals, the present invention provides a ring IN terminals with memory, the memory having a ring terminal insertion force can be achieved without docking, by raising the temperature in operation to ensure distribution of the terminals and the contact t...
