Description

Technical Field

[0001] The utility model relates to the technical field of FAKRA to SMP port connectors, in particular to a large-angle FAKRA to SMP port connector. Background Art

[0002] Existing FAKRA to SMP port connectors usually rely on sealing rubber rings at the two ports of the connector to achieve a sealed connection between the terminal blocks on both sides and the connector body. The terminals and connectors on both sides are combined into a straight plate type.

[0003] However, some equipment requires connectors with bevels or corners, such as cameras. This type of connector includes a straight segment and an inclined segment. The angle between the inclined segment and the horizontal plane is determined according to actual needs, and different bevel angles will also cause certain changes in the internal structure of the connector.

[0004] For example, when changing from a small bevel angle to a large bevel angle structure, the length and corner position of the center pin, the length and fixed position of the insulator in the connector will all change. Accordingly, the installation and connection of other components also need to be adjusted accordingly.

[0005] This type of angled connector mainly meets the needs of equipment docking in special spaces and angles, and also needs to ensure high waterproof performance.

[0006] Furthermore, since the angled connector needs to consider the installation connection between the device housing, the installation connection between it and the shielding shell, the setting of the outer conductor, etc., it cannot be obtained by bending the existing connector structure, and the ease of assembly and production cost need to be fully considered.

[0007] Therefore, there is an urgent need for a large-angle FAKRA to SMP port connector that can solve one or more of the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] To make the above-mentioned objects, features, and advantages of the present invention more readily understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] The utility model discloses a large-angle FAKRA to SMP port connector, which includes: Figure 3-Figure 5 As shown, the radio frequency component 3 is provided with an outer conductor 30, a main body 31, a seal 35, a center needle 32 and an insulator;

[0032] The lower end of the main body 31 is assembled with the upper end of the outer conductor 30. A sealing groove 311 is formed on the outer sidewall of the main body 31, and a first sealant 4 (coated) is installed in the sealing groove 311. The sealing member 35 is limitedly installed (limited and clamped by a step structure) in the through hole of the main body 31. The through hole and outer sidewall of the sealing member 35 are both provided with a plurality of sealing flanges 350 connected end to end. The sealing flanges 350 are tightly fitted with the through hole of the main body 31.

[0033] One end of the center needle 32 is inclined, and the insulator is installed (rubber-coated) on the center needle 32. The insulator isolates the center needle 32 from the outer conductor 30 and the main body 31. The upper end of the center needle 32 is inserted into the through hole of the main body 31, and the lower end of the center needle 32 is inserted into the through hole of the outer conductor 30 to form an SMP port. The upper end of the center needle 32 passes through the through hole of the sealing member 35 and is tightly fitted with the corresponding sealing flange 350.

[0034] Combine Figure 1-Figure 3As shown, the outer periphery of the RF component 3 is wrapped with a shell 1, and the shell 1 forms a first mounting cavity 10. The shell 1, the main body 31, and the center pin 32 form a FAKRA port, and the FAKRA port or the SMP port is an inclined port;

[0035] The first mounting cavity 10 is installed with a second sealant 5 connected head to tail, and the second sealant 5 is tightly fitted to the outer wall of the RF component 3. The through hole of the outer conductor 30 is installed with a third sealant 6 connected head to tail, and the third sealant 6 is tightly fitted to the lower end of the center needle 32 passing through. The third sealant 6 is tightly fitted to the insulator (such as the second insulator 34).

[0036] Specifically, combined Figure 3 As shown, Figure 3 The FAKRA port is an inclined port, with an angle of 50-80 degrees with the vertical plane; preferably, the angle of 60 degrees with the vertical plane. Furthermore, a groove is provided at the connection between the housing 1 and the RF component 3 within the first mounting cavity 10. This groove is used to install the second sealant 5. The second sealant 5 can be clamped onto the outer wall of the RF component 3 via a stepped structure to enhance the connection security.

[0037] Specifically, combined Figure 2 、 Figure 3 As shown, the shielding shell 2 is installed in the first mounting cavity 10, and one end of the RF component 3 is inserted into the shielding shell 2. The first mounting cavity 10 is formed with an outwardly extending docking post 11, which is plugged into the shielding shell 2 (fixed by hot riveting) to achieve a fixed installation position. Furthermore, the shielding shell 2 can be provided with a spring to elastically fasten one end of the RF component 3. The first mounting cavity 10 can be formed with a plurality of rubber plates or rubber posts for interference fit with the shielding shell 2.

[0038] Specifically, combined Figure 3-Figure 5 As shown, the upper end of the outer conductor 30 is provided with a docking slot 300 connected to its through hole, the free end of the docking slot 300 is provided with a plug-in flange 301, and the lower end of the main body 31 is provided with a cover plate 310 covering the docking slot 300. The plug-in flange 301 is inserted into the main body 31 and fastened to the connection. This structure can facilitate the splicing of the outer conductor 30 and the main body 31; furthermore, a plurality of fastening protrusions 302 are provided on the outer side wall of the plug-in flange 301 to enhance the fastening effect.

[0039] Specifically, combined Figure 3 、 Figure 5As shown, the insulator includes: a first insulator 33 and a second insulator 34. The first insulator 33 and the second insulator 34 are overmolded on the center pin 32. The first insulator 33 is arranged at the upper end of the center pin 32, and the second insulator 34 is arranged at the lower end of the center pin 32. The first insulator 33 is installed in the through hole of the main body 31, and the second insulator 34 is installed in the docking notch 300.

[0040] The center pin 32 is formed with a separation protrusion 320. The separation protrusion 320 separates the first insulator 33 and the second insulator 34. The separation protrusion 320 is electrically isolated from the main body 31 and the outer conductor 30. The main body 31 and the outer conductor 30 are combined to form an internal cavity 7. The separation protrusion 320 is exposed in the internal cavity 7.

[0041] The first insulator 33 is provided with a first limiting protrusion 330, and the second insulator 34 is provided with a second limiting protrusion 340.

The second insulator 34 is provided with a flange 341 on a side facing the cover plate 310, and the flange 341 extends toward the cover plate 310.

[0042] To ensure that the height of one end of the RF component 3 above the top surface of the housing 1 is not too high, and that the other end of the RF component 3 does not protrude too much from the shielding shell 2, the installation depth of the second insulator 34 in the through hole of the outer conductor 30 will be very shallow. By providing the flange 341, in extreme cases, the contact surface between the second insulator 34 and the cover plate 310 is larger, thereby being more able to withstand force and also facilitating assembly.

[0043] In summary, the RF component is formed by assembling the main body and the outer conductor, which can meet the requirement that the angle between the inclined port and the vertical plane is 50-80 degrees, especially 60 degrees, while reducing the height of the RF component on the housing. It ensures that the port of the RF component does not protrude too much from the shielding shell. At the same time, the housing can provide more space to install a larger shielding shell, and facilitates assembly and production.

[0044] Through the above-mentioned seals, the first, second and third sealants form a multi-level seal to ensure the waterproof performance of the RF component. The shell molded around the RF component can make the shell and the RF component fit tightly to enhance the overall waterproof performance and ensure that the final camera product has excellent waterproof performance; the insulator overmolded on the center pin not only ensures the electrical isolation between the center pin and the outer conductor and the main body, but also improves the concentricity and concentricity stability of the interface of the formed connector.

[0045] The embodiments described above merely represent one or more implementations of the present invention. While their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
