Description

Technical Field

[0001] The utility model relates to the field of radio frequency coaxial connectors, in particular to a curved wire end connector with two power PINs. Background Art

[0002] RF coaxial connectors include straight and angled types. The angled type refers to the male or female connector where the body, shell, and cable form an angle, usually 90 degrees. The purpose is to shorten the long section of the connector, that is, to bend the part where the body and cable are tightly connected 90 degrees and move it to the lower end, thereby adapting to the use requirements of cramped space.

[0003] To meet the power supply requirements of the equipment and the wiring requirements of the system, some RF coaxial connectors integrate power cord plug-in and docking structures.

[0004] The RF docking structure and power docking structure of the existing connector are set separately, and the locking structures of the RF terminals and the power terminals are also set separately; when the terminals of the straight connector are subjected to axial plug-in and pull-out force, the force will be transmitted to the fastener at the rear end. This fastener fixes the cable sheath and the connector together, while the terminals of the curved connector directly transmit the force to the bend (the cable and the terminal are welded or riveted). Therefore, relatively speaking, the holding force and anti-breakaway performance of the curved connector are weaker, so it is generally necessary to add a secondary locking structure. The same is true for the power cord plug-in and pull-out docking structure.

[0005] However, the existing secondary locking structures of the RF terminal and the power terminal are independent of each other, the integrity between the components is poor, and the locking components are small in size, resulting in relatively high production and assembly costs.

[0006] Therefore, there is an urgent need for a curved wire end connector with two power PINs that can solve one or more of the above problems. Utility Model Content

DETAILED DESCRIPTION

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.

[0033] like Figures 1-8 As shown, the utility model discloses a curved wire end with two power PIN connectors, which includes: a housing 1, a Figure 3-Figure 6 As shown, the housing 1 is provided with a first through hole 10 and a second through hole 11. The main body 2 is fixedly installed in the first through hole 10. The mounting through hole 20 of the main body 2 is installed with an insulator 3. The terminal 4 is installed in the insulator 3. The power terminal 90 is fixedly installed in the second through hole 11. The power terminal 90 is electrically connected to the power line 9.

[0034] Combine Figure 2 、 Figure 5 、 Figure 8 As shown, the main body 2 is provided with a first side groove 21 and a second side groove 22, and the main body 2 is provided with a bent portion 23. The connecting hole 230 of the bent portion 23 is connected to the mounting through hole 20. The core wire 80 of the cable 8 passes through the connecting hole 230 and is electrically connected to the terminal 4;

[0035] Combine Figure 6 、 Figure 8 As shown, the housing 1 is provided with first connecting portions 14 on both sides, the housing 1 is provided with a snap-fit ​​spring 15 snap-fitted with the second side groove 22 , and the housing 1 is provided with a first limiting groove 16 and a second limiting groove 17 ;

[0036] Combine Figure 3-Figure 8 As shown, the cover 7 is provided with a first fastening portion 70 that is engaged with the first connecting portion 14, the cover 7 is provided with a first connecting column 71 that is engaged with the first limiting groove 16 and the first side groove 21, and the cover 7 is provided with a second connecting column 72 that is inserted into the second limiting groove 17, and the second connecting column 72 is engaged with another first side groove 21 and the power terminal 90.

[0037] It should be noted that, in some embodiments, Figure 2-Figure 4 As shown, the rear end opening of the mounting through hole 20 is installed with a rear cover 5, and the welding end of the terminal 4 and the core wire 80 is sealed by the rear cover 5. Figure 4 As shown, a card slot 110 is provided in the second through hole 11, and the card slot 110 is engaged with the power terminal 90. Figure 6 As shown, the housing 1 is provided with a notch 19 , which is opposite to the card slot 110 . The user can release the engagement between the power terminal 90 and the card slot 110 through the notch 19 and then remove the power terminal.

[0038] Specifically, combined Figure 2 、 Figure 5 As shown, the connector further includes a fastener 6 and an elastic fastener 24. The fastener 6 presses the braided conductor 81 of the cable 8 against the outer wall of the bent portion 23. The elastic fastener 24 is fixedly mounted within the mounting hole 20 and is used to secure the inserted connector. Furthermore, the outer wall of the bent portion 23 is provided with knurling 231 to strengthen the fastening of the braided conductor 81.

[0039] Specifically, combined Figure 1 、 Figure 6 As shown, the housing 1 is provided with a groove 12, in which an insertion and extraction spring 13 is provided. The insertion and extraction spring 13 is used to engage with the docking connector. Pressing grooves 120 are provided on both sides of the groove 12, and the insertion and extraction spring 13 can be pressed through the pressing grooves 120. When the insertion and extraction spring 13 is not pressed through the pressing grooves 120, the connector is difficult to disengage. Only when the insertion and extraction spring 13 is pressed through the pressing grooves 120 can the connector be smoothly disengaged, thereby reducing the risk of connector disengagement due to accidental touch.

[0040] Specifically, combined Figure 7 、 Figure 8 As shown, docking grooves 150 are formed on both sides of the snap-fit ​​spring piece 15, and the cover 7 is formed with docking flanges 73 inserted into the docking grooves 150, thereby limiting the moving direction of the snap-fit ​​spring piece 15;

[0041] The housing 1 is provided with a third limiting groove 18, and the cover 7 is provided with a limiting flange 75. The limiting flange 75 engages with the third limiting groove 18 to strengthen the connection between the housing 1 and the cover 7, thereby preventing the torsional force from being entirely borne by the first and second connecting columns and the first fastening portion 70, thereby improving the reliability of the connector;

[0042] The cover 7 is provided with a limited surface 74, combined with Figure 5 The limiting surface 74 abuts against the snap-on spring 15 and limits the snap-on spring 15 from bending outward. During the process of plugging and unplugging the connector, the snap-on spring 15 will be subjected to radial force. During this period, the limiting surface 74 supports the snap-on spring 15 to prevent the snap-on spring 15 from being excessively deformed and causing the installation of the main body 2 to become loose.

[0043] In summary, by providing corresponding structures on the housing, main body and cover to achieve secondary locking of the power terminals and the main body, the firmness of the components after assembly is improved, and the reliability of the connector during use is guaranteed; furthermore, by achieving multiple locking of the main body and the power terminals at one time through the cover, assembly is simpler and the manufacturing cost of the connector is lower.

[0044] 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.
