Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an RF connector which effectively reduces the risk of contact breakage. Background Art

[0002] RF connector, or radio frequency coaxial connector, is generally considered to be a component installed on a cable or installed on an instrument. As a component that electrically connects or separates transmission lines, RF connector is a mechatronics product that mainly acts as a bridge.

[0003] After searching, the application with patent number CN202221700749.3 discloses an RF connector that effectively reduces the risk of contact failure, which includes a plastic body, a static terminal embedded in the plastic body, a dynamic terminal installed on the plastic body, and an iron shell component arranged on the upper surface of the plastic body and enclosing the static terminal and the dynamic terminal in a working groove, the static terminal has a first free end that is cantilevered and extends into the working groove, and the dynamic terminal has a second free end that is cantilevered and extends into the working groove. A contact protrusion protruding downward is arranged on the static terminal near the first free end, and the second free end is held against the contact protrusion; the second free end and the contact protrusion adopt line contact, or surface contact, or at least two or more point contacts;

[0004] Although the RF connector that effectively reduces the risk of broken contact changes the original single-point contact into multi-point contact or line contact or surface contact, thereby reducing the risk of poor contact between the moving terminal and the static terminal, the contact protrusion of the static terminal of the RF connector that effectively reduces the risk of broken contact is exposed, and flux or solder paste may still adhere to the contact protrusion, thereby causing the problem of poor contact between the static terminal and the moving terminal.

[0005] Therefore, we propose an RF connector that effectively reduces the risk of contact breakage. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an RF connector that effectively reduces the risk of contact breakage, thereby solving the problem that the contact protrusions of the static terminals of the prior art devices are exposed, and flux or solder paste may still adhere to the contact protrusions, thereby causing poor contact between the static terminals and the dynamic terminals.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: an RF connector that effectively reduces the risk of disconnection, comprising a plastic body, an iron shell component assembled on the plastic body, a plug hole formed on the top surface of the iron shell component, a groove formed on the top surface of the plastic body, a static terminal fixedly mounted on the side wall of the groove, and a mounting plate assembled inside the plastic body;

[0008] Support blocks are fixedly installed on both sides of the bottom surface of the groove, spring sheets are fixedly installed on both sides of the mounting plate, the free ends of the spring sheets are pressed on the top of the support blocks, an arc-shaped moving terminal is fixedly installed on one side of the mounting plate close to the static terminal, a clamping hole is provided on the top surface of the moving terminal, the static terminal is an arc-shaped plate with the same contour as the moving terminal, and a contact column is fixedly installed on the inner wall of the static terminal.

[0009] Preferably, the size of the contact column is the same as that of the snap-in hole, and the contact column is snap-into the inside of the snap-in hole, so as to increase the contact surface between the static terminal and the dynamic terminal, and also to increase the stability when the static terminal and the dynamic terminal are in contact, thereby avoiding the situation where the dynamic terminal and the static terminal are disconnected.

[0010] Preferably, the arc surface of the contact column is provided with a bevel, and the bevel contacts the end face of the movable terminal, wherein when the mounting plate is pushed toward the inside of the groove, the end face of the movable terminal will contact the bevel, and the mounting plate can be bent downward through the bevel to facilitate the contact column to be clamped inside the clamping hole.

[0011] Preferably, an L-shaped clamping plate is fixedly mounted on one side of the mounting plate away from the clamping hole, and one end of the L-shaped clamping plate is clamped inside the clamping slot, wherein the mounting plate is conveniently fixed to the plastic body by the L-shaped clamping plate.

[0012] Preferably, the L-shaped card plate and the card slot are interference fit, wherein the interference fit can make the connection between the L-shaped card plate and the card slot more stable.

[0013] The utility model provides an RF connector that effectively reduces the risk of contact breakage and has the following beneficial effects:

[0014] 1. The RF connector that effectively reduces the risk of contact failure can shield the flux or solder paste from contacting the inner wall and the contact column of the static terminal by setting the static terminal to an arc shape, which is beneficial to avoid the flux or solder paste adhering to the inner wall or the contact column of the static terminal. By clamping the contact column inside the clamping hole and the inner wall of the static terminal in contact with the surface of the dynamic terminal, the purpose of increasing the contact area between the static terminal and the dynamic terminal is achieved, which is beneficial to avoid the poor contact between the dynamic terminal and the static terminal. The problem that the contact protrusion of the static terminal of the existing device is exposed to the outside and the flux or solder paste may still adhere to the contact protrusion, thereby causing poor contact between the static terminal and the dynamic terminal, is solved;

[0015] 2. The RF connector effectively reduces the risk of contact breakage. The mounting plate can be bent downward by the inclined surface to facilitate the contact column to be clamped inside the clamping hole, which is beneficial to increase the stability when the static terminal and the dynamic terminal are in contact. The mounting plate is conveniently fixed to the plastic body by the L-shaped clamping plate. BRIEF DESCRIPTION OF THE DRAWINGS

By clamping the contact post 41 in the inside of the clamping hole 34, and the inner wall of the static terminal 4 contacts the surface of the movable terminal 33, the purpose of increasing the contact area between the static terminal 4 and the movable terminal 33 is achieved, which is conducive to avoiding the situation where the movable terminal 33 and the static terminal 4 have poor contact, and solves the problem that the contact protrusion of the static terminal of the existing device is exposed to the outside, and the flux or solder paste may still adhere to the contact protrusion, thereby causing the poor contact between the static terminal and the movable terminal;

[0025] Embodiment 2:

[0026] like Figure 1-4 As shown: the arc surface of the contact column 41 is provided with an inclined surface 42, and the inclined surface 42 contacts the end surface of the moving terminal 33. An L-shaped clamping plate 31 is fixedly installed on the side of the mounting plate 3 away from the clamping hole 34. One end of the L-shaped clamping plate 31 is clamped in the inside of the clamping groove 12. The L-shaped clamping plate 31 and the clamping groove 12 are interference fit.
