Description

Technical Field

[0001] The invention relates to a connector, in particular to a floating TMA-KFD microstrip connector with flange for a mounting plate. Background Art

[0002] At present, the conventional TMA-KFD microstrip connector with flange is installed on the mounting plate, and the microstrip needs to be soldered on the corresponding circuit board. The microstrip is fixed and the connector port is also fixed. The traditional TMA-KFD connector has no floating amount and cannot be compressed axially.

[0003] Since there is no axial floating amount, it is impossible to make elastic contact during use. When multi-channel connectors of the same type are installed on the same mounting board, there is a floating error in the spacing between the two matching mounting boards. The error will cause each pair of connectors installed on the two mounting boards to not have good contact, and signal transmission cannot be guaranteed. In addition, since the connector has no floating structure, there is an error in the spacing between the mounting boards, which will cause the connector to be damaged due to hard contact. Therefore, a floating TMA-KFD microstrip connector with flange for mounting boards is designed to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present invention and for the convenience of understanding by those skilled in the art.

[0010] Furthermore, the left and right ends of the plug body are respectively provided with a first jack and a second jack, and the contact head of the inner conductor is inserted into the second jack. In this solution, the first jack is used for plugging the connector with the external connector, and the second jack is plugged with the contact head of the inner conductor to complete the docking inside the connector.

[0011] Furthermore, the right end of the plug body is provided with a circle of evenly distributed first slots.

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0023] Example: See attached Figure 1 and attached Figure 6 As shown, this embodiment provides a floating TMA-KFD microstrip connector with flange for mounting a board, comprising: The fixing unit comprises a first installation shell 1, an inner conductor 2 is arranged inside the first installation shell 1, a first insulating member 3 is arranged between the inner conductor 2 and the first installation shell 1, a connecting shell 4 is sleeved on the contact head 26 of the inner conductor 2, and a flange 5 is arranged on the outer wall of the first installation shell 1; the right end of the inner conductor 2 is press-fitted with the first insulating member 3, and the connecting shell 4 is press-fitted with the first installation shell 1; The floating unit includes a second mounting shell 6, a plug-in body 7 is arranged inside the second mounting shell 6, and a second insulating member 8 is arranged between the plug-in body 7 and the second mounting shell 6; the left end of the plug-in body 7 is press-fitted with the second insulating member 8, and the first insulating member 3 is press-fitted with the second mounting shell 6; A spring 9 is sleeved on the right end of the second installation housing 6 . The floating unit is inserted into the first installation housing 1 along the axial direction and is connected to the fixed unit in a floating manner through the spring 9 .

[0024] Due to the usage scenario that the microstrip end needs to be soldered on the circuit board and cannot be moved, otherwise the circuit board will be damaged. Therefore, the microstrip part at the right end of the inner conductor 2 is fixed, and the left end part floats with the first mounting shell 1 as a whole for plugging and unplugging.

[0025] The first mounting shell 1, the inner conductor 2 and the first insulating member 3 are fixed together and mounted on a mounting board, and the microstrip is welded on a corresponding circuit board.

The contact head 26 is crimped on the first mounting shell 1, and the second mounting shell 6 is connected to the contact head 26. During the axial insertion and removal of the second mounting shell 6, the contact head 26 always remains reliably connected to the second mounting shell 6.

[0027] See attached Figure 2 and attached Figure 3 As shown, the inner wall of the first installation housing 1 is provided with a first inner step 10, a second inner step 11, a third inner step 12 and an inner ring groove 13 from right to left; the first insulating member 3 is provided at the first inner step 10, and the connecting housing 4 is provided at the second inner step 11; the outer wall of the second installation housing 6 is provided with a first outer step 14, a second outer step 15 and an outer ring groove 16 from right to left; the second inner step 11 is provided correspondingly to the first outer step 14, the third inner step 12 is provided correspondingly to the second outer step 15, and the inner ring groove 13 is provided correspondingly to the outer ring groove 16. In this embodiment, the setting of the steps can achieve the functions of limiting and positioning, facilitate the determination of the installation position of each part structure, and improve the accuracy of installation.

[0028] See attached Figure 1 As shown, a snap ring 17 is arranged in the outer ring groove 16, and the outer part of the snap ring 17 is abutted against the outer ring groove 16, and the groove width of the inner ring groove 13 and the groove width of the outer ring groove 16 are both greater than the thickness of the snap ring 17. In this embodiment, the snap ring 17 is installed between the outer ring groove 16 and the inner ring groove 13, which can limit the first installation housing 1 and prevent the installed floating unit from moving out to the left; the groove width of the inner ring groove 13 and the outer ring groove 16 are both greater than the thickness of the snap ring 17, so that the snap ring 17 can move left and right in the groove, and cooperate with the action of the spring 9, so that the second installation housing 6 can float left and right inside the first installation housing 1.

[0029] See attached Figure 1 As shown, the two ends of the spring 9 are respectively disposed on the first outer step 14 and the outer step of the connecting housing 4.

[0031] A step is also provided on the first mounting shell 1 with flange 5. The steps on the two shells are used to position the floating second mounting shell 6. The upper and lower limits of the floating size can be designed according to actual conditions. The two shells are connected by a clamping ring 17 to ensure that the floating second mounting shell 6 is installed in the first mounting shell 1 with flange 5.

[0032] See attached Figure 4 As shown, the left and right ends of the plug body 7 are respectively provided with a first jack 18 and a second jack 19, and the contact head 26 of the inner conductor 2 is inserted into the second jack 19. In this embodiment, the first jack 18 is used for plugging the connector with an external connector, and the second jack 19 is plugged with the contact head 26 of the inner conductor 2 to complete the docking inside the connector. A circle of uniformly distributed first card slots 20 are provided at the right end of the plug body 7. In this embodiment, the design of the card slot makes the right end of the plug body 7 elastic, and when the contact head 26 is inserted into the second jack 19, the second jack 19 can be stretched open, which is convenient for plugging the inner conductor 2 with the plug body 7.

[0033] See attached Figure 5 As shown, the left end of the connecting housing 4 is provided with a circle of evenly distributed second slots 21. In this embodiment, the design of the slots makes the left end of the connecting housing 4 elastic, which facilitates the plugging between the second mounting housing 6 and the connecting housing 4.

[0037] Installation method: During installation, first assemble the inner conductor 2 of the connector with microstrip, the first insulating part 3 and the first mounting shell 1 with flange 5; then press fit the outer connection shell 4 on the contact head 26 with the first mounting shell 1 with flange 5; then assemble the floating second mounting shell 6, the plug-in body 7 and the second insulating part 8 together; then put the spring 9 on the first outer step 14 of the second mounting shell 6, wherein the pressure required for compression can be achieved by adjusting the specifications of the spring 9 according to actual needs; finally, put the first sealing ring 23 into the first mounting groove 22 of the second mounting shell 6, and use the snap ring 17 pliers to install the snap ring 17 between the second mounting shell 6 and the first mounting shell 1, and the snap ring 17 can slide axially with the spring 9. After the installation is completed, the left end of the second mounting shell 6 is exposed from the left end of the first mounting shell 1, and the distance between the two is L, so that the maximum axial compression distance of the connector is L, and the maximum floating distance L is set according to actual needs.
