Problems solved by technology

However, the depth of the groove in the prior art is close to the axis position of the self-locking screw, which requires a large force to be screwed into the fastener, but the resulting rebound force is small, and the locking effect is poor. The wall thickness between the grooves is close to the width of the groove. When screwing in, due to the excessive force on the groove, the wall thickness is too thin, especially for self-locking screws used in miniaturized radio frequency devices, self-locking screws are more likely to occur. The phenomenon of broken thread segment

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] refer to figure 1 and figure 2 , a self-locking screw 100 provided by the present invention includes a threaded section 10 and a tuning section 20 formed at one end of the threaded section 10 .

[0024] The threaded section 10 includes a first threaded portion 11, a second threaded portion 13, and an elastic portion 12 connected between the first threaded portion 11 and the second threaded portion 13, and the tuning section 20 is formed on the second threaded portion 13 away from the elastic portion. 12 at one end.

[0025] The elastic portion 12 is provided with two offset and symmetrical radial slots 121 . The two radial slots 121 are respectively adjacent to the first threaded portion 11 and the second threaded portion 13 . Preferably, the two radial slots 121 respectively extend to the connection between the elastic portion 12 and the fi...

Abstract

The invention relates to a self-locking screw and a self-locking assembly using the same. The self-locking screw comprises a threaded segment and a tuning segment formed at one end of the threaded segment. The threaded segment comprises a first threaded portion, a second threaded portion and an elastic portion connected between the first threaded portion and the second threaded portion. The tuningsegment is formed at the end, away from the elastic portion, of the second threaded portion. Two radial grooves which are symmetric in a staggered mode are formed in the elastic portion. The two radial grooves are close to the first threaded portion and the second threaded portion correspondingly. The axial distance between the two radial grooves is not smaller than twice the width of the radialgrooves. The depth of each radial groove is greater than half of the outer diameter of the elastic portion and smaller than the outer diameter of the elastic portion. By means of the self-locking screw and the self-locking assembly using the same, stress on the groove positions when the self-locking screw is screwed into a fastener can be reduced, greater resilience force can be produced in the groove positions, the locking effect is improved, the strength of the groove positions is improved, and no fracturing phenomenon occurs.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of radio frequency communication, in particular to a self-locking screw and a self-locking assembly using the self-locking screw. [0003] 【Background technique】 [0004] At present, the self-locking components used for radio frequency devices generally include fasteners and self-locking screws installed in the fasteners. The threaded section of the self-locking screw is more commonly used as a structure of two dislocated threads plus two slots. During the process of inserting into the fastener, the groove is deformed due to the force, so that the two dislocated threads can cooperate with the internal thread inside the fastener. Self-locking screw produces self-locking. However, the depth of the groove in the prior art is close to the axis position of the self-locking screw, which requires a large force to be screwed into the fastener, but the resulting rebound force is small, and the locking effect...
