Detailed Description
The invention is described in further detail below with reference to the drawings and examples, which are not intended to be limiting.
Referring to the drawings 1-4, a multi-contact spring jack with locking comprises a spring rear sleeve 1 and a spring ring 2, wherein the spring rear sleeve 1 and the spring ring 2 are both made of metal materials, the spring rear sleeve 1 is integrally hollow cylindrical, an inner cavity for being inserted with a ball head plug is arranged in the spring rear sleeve, the inner cavity is open at the end part, two annular grooves are formed in the inner wall of the inner cavity at a certain axial distance along the inner wall, each groove extends along the circumferential direction of the inner wall, one spring ring 2 is arranged in each groove, and the spring ring 2 is radially and axially positioned by the grooves; the spring rear sleeve 1 is assembled and fixed with an insulator 7 of the connector, barbs 6 are arranged on the outer circular surface of the spring rear sleeve 1, and the insulator 7 is penetrated through the barbs 6 to be fixed in a strong manner. The number of barbs 6 may be at least one or may be plural.
Further, a rotation stopping plane 5 is arranged on the outer wall of the spring rear sleeve 1, and the rotation stopping plane 5 can be attached to the insulator 7, so that rotation between the spring rear sleeve 1 and the insulator 7 is avoided.
The spring ring 2 is an inclined ring spring, the groove bottom of the groove is of an arc-shaped design and is matched with the outer circle shape of the spring ring 2, and the diameter of the spring ring 2 is larger than the depth of the groove, so that the inner circular surface of the spring ring 2 protrudes out of the inner wall of the spring rear sleeve 1.
Among the two bevel ring springs, the bevel ring spring close to the jack opening is a front spring 3, and the bevel ring spring far away from the jack opening is a rear spring 4. Taking fig. 5 as an example, the front end of the ball head plug 8 is a plug ball body 10, a circle of concave grooves are arranged between the plug ball body 10 and the plug polish rod 9, and in the process of inserting and extracting the ball head plug 8, the plug ball body 10 is contacted with the front spring 3 and then contacted with the rear spring 4, and the grooves can provide opposite-inserting hand feeling for the inserting process; moreover, in the insertion and extraction processes of the ball plug 8, the two bevel ring springs have different work division actions, the front spring 3 is reliably contacted with the plug polish rod 9, the ball plug 8 is ensured to be reliably contacted in place, and the rear spring 4 is mainly matched with the plug ball 10 to provide a locking function, specifically: the position where the rear spring 4 contacts with the plug sphere 10 is located outside the largest diameter of the sphere, namely, located on the side of the sphere facing the opening of the jack, and the rear spring 4 can play a role in locking the plug sphere 10 because the largest diameter of the plug sphere 10 is equivalent to the inner diameter of the spring sleeve 1 and the inner circle of the spring ring 2 protrudes out of the inner wall of the spring sleeve 1.
In the opposite-plug fit of the two bevel ring springs and the ball plug 8, the front spring 3 is in interference fit with the plug polish rod 9, the rear spring 4 is in contact with the plug ball 10, and the contact position of the plug ball 10 with the rear spring 4 is located on the outer side of the maximum diameter of the ball head, so that the plug ball 10 can radially squeeze the rear spring 4 in the plug pulling process, and the locking function of the rear spring 4 can be exerted after the plug is inserted into the jack.
Fig. 5-7 show opposite plug diagrams of several ball head forms and jack structures of the invention, wherein the ball head plug 8 in the figures comprises a plug polish rod 9 and a plug ball body 10 arranged at the end part of the plug polish rod 9, the opposite plug hand feeling and locking function are provided by the contact fit between the structural mutation of the appearance of the plug ball body 10 and the rear spring 4, the locking retaining force is provided for interference fit in the process of pulling out the plug ball body 10 and the rear spring 4, multiple ball heads can be compatible by the contact fit between the front spring 3 and the plug polish rod 9, multi-point contact can be realized by an oblique ring spring annular structure, in addition, the ball head plug 8 and the oblique ring spring are radially compressed, the stable elastic force of the spring can be realized by designing proper compression amount, and long-service-life application is realized.
