Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an SMA type curved microstrip connection connector with inner and outer conductors not coaxial. Background Art

[0002] The SMA type curved microstrip connector is a special design for connecting inner and outer conductors in a non-coaxial manner, in which the inner center conductor and the outer conductor do not share the same axis. Connectors of this design are usually used in application scenarios where conductors need to be connected in different directions or positions, such as vertical or oblique connections. The SMA type curved microstrip connector allows the connection of conductors in a limited space, especially when the conductors need to extend in different directions. This connector design helps to optimize the circuit board layout so that the conductors can be arranged more flexibly to meet specific engineering needs. The SMA type curved microstrip connection with non-coaxial connectors for inner and outer conductors provides more flexibility and optionality for electronic design, making it possible to achieve reliable connections in complex layouts.

[0003] The mechanical interference fit of the two connecting parts of the outer conductor of the commonly used SMA curved microstrip connector leads to electromagnetic leakage problems and limits the application of the connector in environments where the inner and outer conductors need to be in non-coaxial positions. The commonly used SMA curved microstrip connector requires precision processing and adjustment, resulting in high cost and low efficiency. The structure is relatively complex and requires more time and labor for installation and debugging. Therefore, an SMA type curved microstrip connection inner and outer conductor non-coaxial connector is proposed. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides an SMA type curved microstrip connection connector with inner and outer conductors not being coaxial, aiming to improve the problem that the prior art cannot meet the connection requirements when the inner and outer conductors are not coaxial.

[0006] Furthermore, a groove is provided inside the outer conductor.

[0007] Furthermore, a cap is arranged inside the outer conductor, and an outer wall of the cap is rotatably connected to the inside of the groove.

[0008] Furthermore, a fixture groove is arranged inside the pad.

[0009] Furthermore, the two welding pads inside the flange are symmetrically distributed.

[0010] Furthermore, a plurality of the clamp grooves are distributed in a circular array.

[0011] Furthermore, the second insulator component is arranged inside the second central conductor component.

[0012] Furthermore, the insulator component 1 is arranged on the inner side of the central conductor component 1.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the present invention, the layout of the outer conductor part and the center conductor part can effectively solve the problem of the inner and outer conductors not being coaxial. By providing a plurality of clamp grooves inside the pad, it is convenient to fix the connector by the clamping device, thereby increasing the practicality of the connector and improving the work efficiency.

[0015] 2. In the utility model, the distance between the soldering pad and the connector housing is increased to reduce the contact between the soldering pad and the connector, thereby increasing the stability of the connector.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an SMA type curved microstrip connection inner and outer conductor non-coaxial connector, comprising an outer conductor part 1, a center conductor part 3 is arranged inside the outer conductor part 1, an insulator part 5 is arranged inside the outer conductor part 1, a head part 11 is fixedly connected inside the outer conductor part 1, a center conductor part 2 is fixedly connected inside the head part 11, an insulator part 4 is arranged inside the head part 11, an insulator part 3 6 is arranged inside the head part 11, a flange 8 is fixedly connected to one side of the outer wall of the outer conductor part 1, and a welding pad 9 is arranged inside the flange 8.

[0023] Specifically, traditional connectors have difficulty in handling situations where the connected objects are not in the same axis. The head 11 and the outer conductor 1 adopt a non-coaxial design, so that the connector can easily handle connected objects with different axes. This innovation makes the connector more flexible and extensive in practical applications, greatly improving the practicality of the connector. A soldering pad 9 is set inside the flange 8 connected to the outer conductor 1 to solve the problem of short circuit or safety hazard caused by the close distance between the soldering pad 9 and the connector housing, so that the connector has higher safety while ensuring practicality.

[0024] Reference Figure 2 and Figure 3 A groove 12 is opened inside the outer conductor part 1, a cap 7 is arranged inside the outer conductor part 1, the outer wall of the cap 7 is rotatably connected inside the groove 12, a clamp groove 10 is arranged inside the welding pad 9, the two welding pads 9 inside the flange 8 are symmetrically distributed, and a plurality of clamp grooves 10 are distributed in a ring-shaped array, the insulator part 2 5 is arranged on the inner side of the central conductor part 2 3, and the insulator part 1 4 is arranged on the inner side of the central conductor part 1 2.

[0025] Specifically, the pad 9 is provided with a clamp groove 10 to make the clamping device more stable, thereby greatly improving the work efficiency. The stable device clamping can ensure that the connector can maintain stable working performance under various working conditions, avoiding signal loss or damage caused by shaking or loosening of the device. The insulator part 1 4, the insulator part 2 5, the insulator part 3 6 and the outer conductor part 1 of the connector do not have holes inside, but are fixed by injection and brazing. This design effectively prevents electromagnetic leakage, improves the confidentiality performance of the connector, and can increase the wear resistance and corrosion resistance of the connector, thereby extending its service life.

[0026] Working principle: When it is necessary to use an SMA type curved microstrip connection with non-coaxial connectors for inner and outer conductors, first support the two pads 9 through the flange 8 to fix the relative positions of the outer conductor part 1 and the center conductor part 1 2 and the center conductor part 2 3, thereby ensuring the stability and certainty of the connector. The pad 9 protrudes from the tail of the connection disk, so that the pad 9 maintains an appropriate distance from the connector housing to prevent excessive contact, thereby increasing the stability of the connector. Three clamp grooves 10 are provided on the pad 9, which facilitates the fixation of the product on the clamping equipment, improves production efficiency and operational convenience, and steps are provided in the connector. Insulator part 1 4, insulator part 2 5, insulator part 3 6 and the outer conductor part 1 are not opened. The shell is disconnected from the 90-degree curved part of the outer conductor by pouring epoxy resin glue for brazing and fixing, thereby ensuring product reliability and effectively avoiding the hidden dangers of electromagnetic leakage of the connector, thereby improving the stability, production operability, product reliability and electromagnetic compatibility of the connector, and having high practical value and innovation.
