Description

Technical Field

[0001] The utility model relates to the technical field of FAKRA to SMP port connectors, in particular to a small-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 devices, such as cameras, require angled or cornered connectors. These connectors include both straight and angled sections.

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.

[0029] The utility model discloses a small-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;

[0030] 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.

[0031] 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.

A shielding shell 2 is installed in the first mounting cavity 10. The shielding shell 2 abuts against the limiting flange 12 and forms a separation cavity 8 therebetween to meet design requirements.

[0033] One end of the RF component 3 is inserted into the shielding shell 2, and the FAKRA port or the SMP port is an inclined port, that is, the upper and lower positions of the two ports can be swapped as needed, and the angle between the inclined port and the vertical plane is 30-50 degrees, for example, the angle between the inclined port and the vertical plane is 46 degrees;

[0034] 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.

[0036] It should be noted that by adjusting the height of the limiting flange 12, the insertion depth of the lower end of the RF component 3 in the shielding shell 2 is minimized.

The first insulator 33 is installed in the through hole of the main body 31, and the second insulator 34 is installed in the through hole of the outer conductor 30.

[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.
