Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector with adjustable electrical length. Background Art

[0002] Connectors are a component that our electronic engineering technicians often come into contact with. They are key components that connect information during transmission. With the rapid development of information technology, connectors have been increasingly widely used in microwave communications, aerospace navigation, weapon systems, and microwave measurement equipment. They have the advantages of convenient connection, good shock resistance, and high reliability. The form and structure of connectors are ever-changing. With different application objects, frequencies, electrical lengths, and application environments, there are various forms of connectors. For occasions where the connector itself and the environment in which the connector is used have electrical length adjustments, the physical length of the connector itself is mostly achieved by rotating and retracting the shell.

[0003] However, since the internal structures of most connectors in the prior art solutions are too simple, when the staff adjusts the physical length of the connector, it is impossible to change the electrical length of the connector itself, which leads to limitations in the use of the connector. Utility Model Content

[0004] The embodiment of the present application provides a connector with adjustable electrical length, thereby solving the technical problem that the connectors in the prior art solutions have too simple internal structures. When the staff adjusts the physical length of the connector, the electrical length of the connector cannot be changed accordingly, which causes the connector to be limited in use.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A connector with adjustable electrical length, comprising a connector main shell, an external elastic contact piece arranged in the connector main shell, an internal elastic contact piece connected to the connector main shell, an external contact piece sliding in the external elastic contact piece, an internal contact piece sliding in the internal elastic contact piece, and a movable shell for driving the external contact piece and the internal contact piece to move together; the movable shell is connected to both ends of the connector main shell; the external elastic contact piece is arranged at both ends of the internal elastic contact piece; the internal contact piece is arranged in the external contact piece; and the external contact piece is arranged in the movable shell.

[0007] A further technical solution is: the movable housing is threadedly connected to the connector main housing.

[0008] A further technical solution is: the connector with adjustable electrical length also includes a limiter; the limiter is arranged on the connector main housing.

[0009] A further technical solution is: the limiting member is a hexagonal nut.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] Due to the use of the connector main shell, external elastic contact, internal elastic contact, external contact, internal contact and movable shell, the staff can make the external contact slide a certain distance along the external elastic contact by twisting the threaded connection at both ends of the connector main shell, and at the same time make the internal contact slide a certain distance along the internal elastic contact. Since the distance that the external contact slides along the external elastic contact is equal to the distance that the internal contact slides along the internal elastic contact, it can be ensured that the electrical performance of the connector with adjustable electrical length does not change after the electrical length is adjusted. Therefore, while the physical length of the connector is changed, the electrical length of the connector can also be changed, thereby solving the problem of repeatedly replacing connectors and other components when there is a need for electrical length consistency in the project. At the same time, when the adjustable electrical length connector is used in the electrical length consistency project scenario, only one unit is required to solve the problem of repeatedly replacing components.

[0015] The embodiments of the present application provide a connector with adjustable electrical length and an adjustment method, thereby solving the technical problem that the connectors in the prior art solutions have too simple internal structures, and when the staff adjusts the physical length of the connector, the electrical length of the connector itself cannot be changed accordingly, which causes the connector to be limited in use.

[0016] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] A connector with adjustable electrical length, such as Figure 1 and Figure 2 As shown, it includes a connector main housing 1, an outer elastic contact 2 arranged in the connector main housing 1, an inner elastic contact 3 connected to the connector main housing 1, an outer contact 4 sliding in the outer elastic contact 2, an inner contact 5 sliding in the inner elastic contact 3, and a movable housing 6 for driving the outer contact 4 and the inner contact 5 to move together. The movable housing 6 is connected to both ends of the connector main housing 1. The outer elastic contact 2 is arranged at both ends of the inner elastic contact 3. The inner contact 5 is arranged in the outer contact 4. The outer contact 4 is arranged in the movable housing 6.

[0019] The outer elastic contact 2, the inner elastic contact 3, the outer contact 4 and the inner contact 5 are all conductors. Both ends of the inner elastic contact 3 are fixed inside the two groups of outer elastic contacts 2 by insulating media, and the two groups of outer elastic contacts 2 are fixedly connected to the inner cavity of the connector main housing 1 by press-fitting. The two ends of the connector main housing 1 are threadedly connected with a movable housing 6. The two groups of movable housings 6 are provided with outer contacts 4 and inner contacts 5. The inner contact 5 is fixed inside the outer contact 4 by insulating media, and the outer contact 4 is fixed in the inner cavity of the movable housing 6 by press-fitting. A matching distance is set between the inner contact 5 and the outer contact 4, and the distance can ensure that the electrical signal is qualified. A matching distance is set between the inner elastic contact 3 and the outer elastic contact 2, and the distance can ensure that the electrical signal is qualified.

[0020] The limiting member 7 is preferably a hexagonal nut. The limiting member 7 is threadedly connected to the connector main housing 1. The limiting member 7 can limit the moving distance of the two groups of movable housings 6.

[0021] Due to the arrangement of the connector main shell 1, the outer elastic contact 2, the inner elastic contact 3, the outer contact 4, the inner contact 5 and the movable shell 6, the staff can make the outer contact 4 slide a certain distance along the outer elastic contact 2, and at the same time make the inner contact 5 slide a certain distance along the inner elastic contact 3 by screwing the movable shell 6 connected at both ends of the connector main shell 1. Since the sliding distance of the outer contact 4 along the outer elastic contact 2 is equal to the sliding distance of the inner contact 5 along the inner elastic contact 3, it can be ensured that the electrical performance of the connector with adjustable electrical length does not change after the electrical length is adjusted. Therefore, while the physical length of the connector is changed, the electrical length of the connector can be changed, thereby solving the problem of repeatedly replacing connectors and other components when there is a need for electrical length consistency in the project. At the same time, when the connector with adjustable electrical length is used in the electrical length consistency project scenario, only one unit is needed to solve the problem of repeatedly replacing components.

[0022] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0023] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
