Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a coaxial connector and its plug. Background Technology

[0003] like Figure 1 As shown, in the prior art, the contact arm B of the conductive terminal A of the coaxial connector is formed by side-extrusion bending. This structure limits the width and height of the contact arm B of the conductive terminal A to a certain value, which greatly affects the radio frequency performance of the connector. At the same time, this structure causes the conductive terminal A to deform significantly after being snapped together. Summary of the Invention

[0028] This application provides a coaxial connector plug that solves the technical problems of radio frequency performance being affected and significant deformation after terminal engagement in the prior art.

[0029] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0030] By configuring the conductive terminal to include a pressure-bearing part, a locking part, and a connecting part, the pressure-bearing part is a plate-shaped component, the connecting part is connected to a first end of the pressure-bearing part, and the locking part is formed by tearing and bending from a second end of the pressure-bearing part. This narrows the width of the conductive terminal, optimizing radio frequency performance and reducing deformation after the conductive terminal is engaged.

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] The reference numerals in the accompanying drawings include:

[0033] 100 Coaxial connector plug 137 Second lever arm 110 case 138 Fasteners 120 Insulating core 139 Arc structure 130 conductive terminals 200 coaxial connector 131 Pressure-bearing section 300 Coaxial connector socket 132 Card-shaped section 301 Central conductor 133 Connection part 400 coaxial cable 135 Contact end 401 Core wire 136 First lever arm

[0034] like Figures 2 to 4 The following is an embodiment of this application:

[0035] A plug 100 of a coaxial connector is used for fixedly connecting a coaxial cable 400 having core wires 401, and is detachably connected to a socket 300 of the coaxial connector, comprising:

[0036] Casing 110;

[0037] An insulating core 120 is installed inside the housing 110;

[0038] The conductive terminal 130 is embedded in the insulating core 120;

[0039] The conductive terminal 130 includes a pressure-bearing part 131, a locking part 132, and a connecting part 133. The pressure-bearing part 131 is a plate-shaped component. The connecting part 133 is connected to the first end of the pressure-bearing part 131. The locking part 132 is formed by tearing and bending from the second end of the pressure-bearing part 131.

[0040] In this embodiment, the pressure-bearing part 131 is a plate-shaped component, and the engaging part 132 is formed by tearing and bending from the second end of the pressure-bearing part 131. It can be understood that the engaging part 132 is formed by tearing and bending from the middle of the plate-shaped component. Therefore, the width of the engaging part 132 is narrower than the width of the second end of the pressure-bearing part 131. As a result, the overall width of the terminals at the contact point is narrower, which largely maintains the consistency of the transmission line size, reduces the connector's own loss, and thus greatly improves the RF performance of the connector. At the same time, it also reduces the deformation of the conductive terminals after they are engaged.

[0041] The engaging portion 132 has two contact ends 135, which are spaced apart and facing each other along the extension direction of the coaxial cable 400. The extension direction of the coaxial cable is defined as longitudinal (i.e., front-to-back orientation), the direction perpendicular to this extension direction is transverse (i.e., left-to-right orientation), and the mating direction of the coaxial connector plug and socket is defined as vertical or vertical (i.e., up-down orientation). The two contact ends 135 are positioned in the front-to-back orientation. When the coaxial connector plug 100 is connected to the coaxial connector socket 200, the contact ends 135 make front-to-back contact with the center conductor.

[0042] One of the contact ends 135 includes a first lever arm portion 136 formed by tearing and bending from the pressure-bearing portion 131, and a second lever arm portion 137 formed by bending from the bottom of the first lever arm portion 136 toward the other contact end 135.

[0043] The connection between the first lever arm 136 and the second lever arm 137 is an arc structure. The arc structure at the transition connection between the first lever arm 136 and the second lever arm 137 is designed to better release the deformation stress generated when the conductive terminal 130 is inserted into the center conductor 301, thus serving as an insertion guide. The specific shape of the arc structure is not specifically limited in this invention; it can be an inverted U-shape, an inverted C-shape, etc. The first lever arm 136 and the second lever arm 137 are parallel. This increases the contact area between the second lever arm 137 and the center conductor 301 when the plug and socket of the coaxial connector are connected, improving the stability and reliability of the terminal contact.

[0044] Preferably, the angle between the first lever arm 136 and the pressure-bearing part 131 is a right angle, that is, the first lever arm 136 and the pressure-bearing part 131 are set to be perpendicular or approximately perpendicular. Of course, this angle can also be slightly greater than or slightly less than 90 degrees, such as 85 degrees or 95 degrees. Setting this angle to a right angle can increase the length of the straight section of the lever arm, further reducing the deformation after the conductive terminals are engaged.

[0045] It should be noted that, in order to meet the requirement of connector minimization, the height and width of the connector terminals should be as small as possible. Specifically, in this invention, while ensuring RF performance and connection reliability, as shown... Figure 5 As shown, the overall height H of the conductive terminal ranges from 0.3 to 0.5 mm, such as 0.5 mm, 0.45 mm, 0.4 mm, 0.3 mm, etc. Figure 6 As shown, the width W at the second end of the pressure-bearing part 131 ranges from 0.3 to 0.6 mm, such as 0.6 mm, 0.5 mm, 0.4 mm, 0.3 mm, etc.

[0046] Preferably, the connecting portion 133 includes two bent fastening portions 138, which are used to clamp the core wire 401 of the coaxial cable 400. Through the clamping connection of the two fastening portions 138, a more reliable electrical connection between the core wire 401 and the connecting portion 133 can be achieved.

[0047] like Figures 7 to 9 As shown, the present invention also includes embodiments:

[0048] A coaxial connector 200 includes a plug 100 of the coaxial connector described above and a socket 300 of the coaxial connector that mates with the plug 100 of the coaxial connector described above. The plug and the socket are detachably connected. When the plug is connected to the socket, the engaging portion 132 on the plug is connected to the center conductor 301 on the socket.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
