Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an RF connector. Background Technology

[0002] RF connectors, also known as radio frequency coaxial connectors, are key components in wireless radio frequency (RF) systems. Primarily used in radio communication, they enable interconnection between devices or modules via high-frequency signal transmission, effectively transmitting radio frequency and microwave signals. RF connectors play a crucial role in radio communication equipment, characterized by their small size, light weight, low power consumption, and high reliability.

[0003] RF connectors typically consist of a plastic component, terminals mounted on the plastic component, and a metal housing enclosing the plastic component. The first end of the terminal is exposed above the first end of the plastic component and the metal housing for connection to a mating electrical connector, and the second end of the terminal is exposed above the second end of the plastic component and the metal housing for connection to a wire harness. The first end of the terminal connecting to the mating electrical connector is configured as a mating end, having at least two elastic arms that enclose an elastic clamping space for insertion of the mating terminal. Therefore, the yielding force of the mating end is a critical parameter in its manufacturing process. The yielding force refers to the amount of elastic deformation of the elastic arm due to force during the mating process until a stable clamping state is reached. This parameter is crucial in the manufacturing process of RF connectors because it directly affects the connection stability and service life of the connector. Specifically, if the yielding force is too large, it means that the elastic arm needs to withstand significant deformation during mating, which may lead to fatigue damage of the elastic arm, thus affecting the long-term stability of the connector.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Please see Figure 1 and Figure 2 , Figure 1 An RF connector structure is shown as an example. Figure 2 An exploded view of an RF connector is shown as an example. The RF connector will be described exemplarily based on the structure shown in the figure. It should be understood that, apart from the technical solutions corresponding to the technical problems necessary to solve this application, the other exemplary structures are merely exemplary, specific, or preferred solutions and should not be used to limit the scope of protection of this application.

[0033] Figure 1 and Figure 2 In the illustrated embodiment, the RF connector includes, from the inside out, terminals 100, an insulating body 200, and a metal housing 300. The terminals 100 can be integrally injection molded within the insulating body 200, inserted into the insulating body 200 via a plug-in method, or formed within the insulating body 200 using any known method. The metal housing 300 encloses the insulating body 200 to provide signal shielding. The metal housing 300 can be attached to the insulating body 200 via, for example, snap-fit, adhesive, or any known method.

[0034] The terminal 100 includes a main body segment 110, a plug-in portion 120 formed at a first end of the main body segment 110, and a wiring portion 130 formed at a second end of the main body segment 110. The plug-in portion 120 is exposed at the first end of the insulating body 200 and the metal housing 300, and is used to plug into and mate with the mating terminal of a mating electrical connector. The wiring portion 130 is exposed at the second end of the insulating body 200 and the metal housing 300, and is used to connect to a wire harness L.

[0035] The main body segment 110 can be in the form of an elongated block structure or a columnar structure, etc. In this embodiment, the main body segment 110 is configured as an elongated block structure. The width of the first end of the main body segment 110 is greater than the width of the rest, which can enhance the strength of the plug-in portion 120 and adapt to the mating terminal.

[0036] Please see Figure 3a The insertion portion 120 includes at least two elastic clamping arms, which enclose an elastic clamping space 121 for inserting a mating terminal. Each elastic clamping arm has at least one protruding rib 122 to enhance its strength, reducing the yielding amount of the elastic clamping arm. The protruding rib 122 can be integrally formed by a stamping process, for example, stamped from the outer side to the inner side of the respective elastic clamping arm, or stamped from the inner side to the outer side of the respective elastic clamping arm. The protruding rib 122 can also be provided on the surface of the elastic clamping arm (including the inner and / or outer sides) as a ridge or protrusion.

[0037] In the illustrated embodiment, the insertion portion 120 includes a first elastic clamping arm 12a and a second elastic clamping arm 12b symmetrically positioned on both sides of the main body segment 110, each bent from both sides of the main body segment 110. Each of the first elastic clamping arm 12a and the second elastic clamping arm 12b includes an arc-shaped segment 123 connected to the main body segment 110 and a bent segment 124 formed on the side of the arc-shaped segment 123 away from the main body segment 110. The curvature centers of the two arc-shaped segments 123 are located inside each other, and the two bent segments 124 are formed by bending the two arc-shaped segments 123 in a direction away from each other. An elastic contact portion 125 is formed at the junction of the arc-shaped segment 123 and the bent segment 124 of the two elastic clamping arms for clamping the mating terminal 100.

[0038] Both the first elastic clamping arm 12a and the second elastic clamping arm 12b are provided with two protruding ribs 122 spaced apart along the length direction of the terminal 100. The two protruding ribs 122 are distributed on their respective arc-shaped segments 123, and each protruding rib 122 is distributed along the arc direction (arc length) of its respective arc segment 123. It should be understood that the two protruding ribs 122 here are only used as a specific example and do not mean that each elastic clamping arm can only have two protruding ribs 122. One protruding rib 122 is provided on each elastic clamping arm (see...). Figure 3b Multiple ribs (122) or more than two are allowed, depending on the specific requirements.

[0039] The wiring section 130 includes a first arm 131 and a second arm 132 standing laterally on both sides of the main body section 110. The first arm 131 and the second arm 132 can be configured to be bent from both sides of the main body section 110. The first arm 131, the second arm 132, and the main body section 110 enclose a receiving space 133 for accommodating the wire harness L. The wire harness L is accommodated in the receiving space 133 and connected thereto, for example, by welding, to achieve electrical conductivity.

[0040] Please see Figure 4 and Figure 5 The insulating body 200 and the terminal 100 are configured to cooperate with each other. In this embodiment, a receiving cavity 201 is formed within the insulating body 200. A first insertion hole 202 is formed at the first end of the insulating body 200, allowing the receiving cavity 201 to communicate with the outside. A second insertion hole 203 is formed at the second end of the insulating body 200, allowing the receiving cavity 201 to communicate with the outside. The terminal 100 is housed within the receiving cavity 201, and the insertion portion 120 of the terminal 100 is exposed through the first insertion hole 202, while the wiring portion 130 is exposed through the second insertion hole 203.

[0041] In this embodiment, the first insertion hole 202 penetrates one side of the insulating body 200 along the thickness direction of the insulating body 200, for example... Figure 4 The upper side shown in the diagram will be referred to as the side containing the first socket 202 below for ease of description. The second socket 203 extends through the second end face of the insulating body 200 along its length, for example... Figure 4 The rear end face is shown in the figure. However, this is not a limitation of the present invention. For example, the first socket 202 may also penetrate one side of the insulating body 200 along the length or width direction, and the second socket 203 may also penetrate one side of the insulating body 200 along the thickness or width direction of the housing.

[0042] In this embodiment, the insulating body 200 includes a main body 210 and a shielding portion 220. The lower side of the main body 210 (the side facing away from the first insertion hole 202) opposite the receiving cavity 201 forms a mounting opening 204 for inserting a terminal 100. The shielding portion 220 can either open or cover the mounting opening 204. For example, the shielding portion 220 can be detachably engaged with the mounting opening 204, for example, via a snap-fit ​​mechanism, to either close or open the mounting opening 204. The shielding portion 220 can also be configured as a thin, bendable shielding block integrally formed with the first end edge of the main body 210, as described in the illustrated embodiment. When the terminal 100 is inserted into the receiving cavity 201, the shielding portion 220 is bent to cover the mounting opening 204. The free end of the shielding portion 220 can be tightly fitted to the mounting opening 204, or it can completely cover the lower side of the main body portion 210. The main body portion 210 and the metal housing 300 can apply force to the shielding portion 220 from opposite directions, thereby restricting the shielding portion 220 to a state that shields the mounting opening 204.

[0043] In this embodiment, the insulating body 200 has an elongated structure when projected onto a horizontal projection plane, with its first end being circular or near-circular and its second end being rectangular or near-rectangular and connected to the first end. A protrusion 211 is formed on the upper surface of the first end of the insulating body 200. Specifically, the protrusion 211 is formed on the upper surface of the main body 210. The protrusion 211 can be configured as a circular or near-circular structure with a diameter smaller than the diameter of the first end, or as a rectangular structure with a cross-sectional area smaller than the cross-sectional area of ​​the first end, or other suitable structures. The first insertion hole 202 penetrates the protrusion 211 along the thickness direction, thereby connecting the accommodating cavity 201 to the outside.

[0044] The insulating body 200 can be connected to the metal housing 300 by a snap-fit ​​connection. For example, the insulating body 200 may have multiple first slots 231, multiple first blocks 232, and / or multiple limiting protrusions 233. For example, a first slot 231 may be provided on each of the two opposite sides of the first end of the insulating body 200; a first block 232 may be provided on each of the two opposite sides of the second end of the insulating body 200; or two mutually spaced limiting protrusions 233 may be provided on the first end face of the insulating body 200.

[0045] Please see Figure 2 and Figure 6The metal housing 300 can be configured to include an inner metal housing 310 covering the insulating body 200 and an outer metal housing 320 covering the inner metal housing 310. A first end of the inner metal housing 310 surrounds the outer periphery of the first end of the insulating body 200 and forms an annular slot 330 therewith, the annular slot 330 being used for insertion of a mating electrical connector. Specifically, the lower portion of the inner metal housing 310 is in close contact with the outer periphery of the first end of the insulating body 200, and the upper portion forms the annular slot 330 between itself and the protrusion 211.

[0046] The metal inner shell 310 includes a first covering portion 311 covering a first end of the insulating body 200 and a second covering portion 312 connected to the first covering portion 311 and covering a second end of the insulating body 200. Both the first covering portion 311 and the second covering portion 312 have through cavities extending along their thickness direction. The metal inner shell 310 can be formed using a bending process.

[0047] The first covering portion 311 has an overall annular structure, with its lower end closely attached to the outer periphery of the first end, and its upper end surrounding the outer periphery of the protrusion 211 and forming the annular slot 330 therewith. The inner circumferential surface of the upper portion of the first covering portion 311 also has an annular protrusion 313 protruding inward, which can be formed on the first covering portion 311 by a stamping process, for example, stamping the first covering portion 311 from the outside inward, thereby causing its inner circumferential surface to protrude inward to form the annular protrusion 313. The second covering portion 312 covers both lateral sides of the second end of the insulating body 200. A second locking block 314 that engages with the first locking slot 231 is provided on the inner circumferential surface of the first covering part 311. A second locking slot 315 that engages with the first locking block 232 is provided on the second covering part 312. A limiting notch 316 that engages with the limiting protrusion 233 is provided on the front end surface of the first covering part 311. The limiting notch 316 is recessed from bottom to top at the front end of the metal inner shell 310.

[0048] Please see Figure 7 The metal housing 320 has a first exposed portion 32a for exposing the annular slot 330, the first socket 202 and the plug-in portion 120, and a second exposed portion 32b for exposing the second socket 203 and the wiring portion 130.

[0049] In this embodiment, the metal outer shell 320 has a third covering portion 321 covering the lower side of the metal inner shell 310 and the insulating body 200; a fourth covering portion 322 formed on both lateral sides of the third covering portion 321 and used to cover both lateral sides of the metal inner shell 310 and the insulating body 200; a fifth covering portion 323 connected to the fourth covering portion 322 and used to cover the upper side of the second end of the insulating body 200 and the metal outer shell 320; and a sixth covering portion 324 connected to the third covering portion 321 and used to cover the wire harness L. The inner side of the third covering portion 321 (the side facing the insulating body 200) is provided with a pressing protrusion 321a for pressing the shielding portion 220, and the pressing protrusion 321a is distributed in a manner perpendicular to the shielding portion 220. The extrusion protrusion 321a can apply extrusion force to the shielding portion 220, making the shielding portion 220 more stably positioned between the metal outer shell 320 and the main body portion 210 of the insulating body 200. The overall length of the third covering portion 321 and the fourth covering portion 322 is consistent with the length of the insulating body 200 and the metal inner shell 310. The sixth covering portion 324 is located at the second end of the third covering portion 321 and is used to cover the end of the wire harness L connected to the terminal 100, thereby fixing and limiting the end, preventing the wire harness L from moving, and improving the connection stability between the wire harness L and the terminal 100.

[0050] The two fourth covering portions 322 are bent from the lateral sides of the third covering portion 321 toward the insertion direction (upward). The two fifth covering portions 323 are respectively bent horizontally from the two fourth covering portions 322 in opposite directions. The sixth covering portion 324 includes a support plate 324a extending from the third covering portion 321 toward the second end, and a third arm 324b and a fourth arm 324c bent from the lateral sides of the support plate 324a toward the insertion direction and in opposite directions.

[0051] Based on the embodiments described above, the RF connector is assembled as follows: First, one end of the wire harness L is inserted into the receiving space 133 of the wiring portion 130 of the terminal 100, and they are soldered together using a soldering process; then, the assembly port 204 is opened, and the terminal 100 is inserted into the receiving cavity 201 of the insulating body 200. After the terminal 100 is inserted into the receiving cavity 201, the shielding portion 220 shields the assembly port 204; at this time, the insertion portion 120 of the terminal 100 is located in the first socket 202, the wiring portion 130 is located in the second socket 203, and the wire harness L is located outside the second end of the insulating body 200; next, the metal inner shell 310 is fitted onto the outer periphery of the insulating body 200, so that the first slot 231 of the insulating body 200 engages with the second locking block 314 of the metal inner shell 310, thereby connecting the insulating body 200 and the terminal 100. The first locking block 232 of the main body 200 engages with the second locking groove 315 of the metal inner shell 310, so that the limiting protrusion 233 of the insulating main body 200 is inserted into the limiting notch 316 of the metal inner shell 310, so that the first covering part 311 of the metal inner shell 310 covers the first end of the insulating main body 200 and forms an annular slot 330 therewith, so that the second covering part 312 of the metal inner shell 310 covers the lateral sides of the second end of the insulating main body 200; finally, the third covering part 321 of the metal outer shell 320 is placed on the lower side of the insulating main body 200 and the metal inner shell 310, so that the fourth covering part 322 and the fifth covering part 323 are bent and covered on the lateral sides and the upper side of the insulating main body 200 respectively; so that the sixth covering part 324 is covered on the outer periphery of the end of the wire harness L near the wiring part 130, thereby completing the assembly of the RF connector.

[0052] Based on the above embodiments, the RF connector of this utility model has the following beneficial effects: By providing ribs on each elastic clamping arm of the terminal, the strength of the mating part can be enhanced and its yielding amount reduced, thereby improving the long-term stability of the connector. The insulating body is configured to include a main body and a shielding part integrally formed at one end of the main body. The main body has a through-hole on the side (lower side) opposite to the mating direction to form an assembly port, which facilitates terminal assembly. Compared with a detachable shielding part, the integrally formed shielding part has a simpler and more efficient manufacturing process, lower cost, and is easier to assemble, reducing assembly complexity. In addition, the integrally formed shielding part is limited at the assembly port by the opposing forces applied by the main body and the metal shell, respectively, without the need for a separate fixing and limiting structure. The metal inner shell is formed by bending, which has a lower manufacturing cost compared to a pull-out shell.

[0053] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
