Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a connector with a gear shifting function. Background Art

[0002] With the development of aviation, aerospace, communications, military electronic countermeasures, and other fields, especially the application of BMS battery management systems, the functional requirements of electrical connectors are constantly increasing. Multiple signal transmission functions need to be integrated into a single connector, and each system is becoming increasingly miniaturized. How to solve the problem of manually switching the state of the connector in a limited space is a technical challenge that needs to be solved. The high reliability and state switching requirements of the connector require a design that realizes internal circuit conversion. The internal circuit switching action is realized through external screwing operation to achieve the state switching function.

[0003] Existing circular connectors only meet single-connection conduction requirements. When power-on, power-off, and short-circuit protection are required on an external interface within the limited space outside the battery, conventional threaded, snap-on, or push-pull quick-lock circular connectors are insufficient. To meet model development requirements, a circular shift connector capable of state switching within a limited space is of practical significance.

[0004] The patent document with announcement number CN113871918A discloses a button connector that can be crimped with wires. The connector includes: an insulating mounting assembly, which has a plurality of plug-in holes; and a plurality of button contacts, which are respectively inserted into the corresponding plug-in holes, and the receiving ends of the button contacts protrude from the plug-in holes; and the other end of each of the button contacts is crimped with a wire; after the printed circuit board presses down the receiving end of the button contact, the signal on the printed circuit board is transmitted to the wire through the button contact. The connector sets the button contact in the plug-in hole of the insulating mounting assembly, so that the receiving end of the button contact protrudes from the plug-in hole, and then presses down the receiving end through the printed circuit board to transmit the signal to the wire; when the receiving end is pressed down, the button in the button contact is compressed to achieve the function of axial floating of the button contact, thereby avoiding damage to the connector due to the insertion force when the button contact is welded.

[0005] The patent document with announcement number CN113161787A discloses a double-floating wool button coaxial sealed connector, including: an outer contact, a center contact, a glass insulator, a solid wool button, an engineering plastic insulator, a hollow wool button, a protective cap and a clamping ring; the present invention adopts a solid wool button and a hollow wool button to respectively set the center contact and the outer contact, so that the signal of the center contact can be reliably transmitted, and the outer contact and the interconnected structural parts jointly achieve the purpose of reliable grounding; the patent adopts a structure in which a glass insulator is encapsulated between the center contact and the outer contact, and the solid wool button and the protective cap are set in the engineering plastic insulator and assembled with the outer contact. Through the application of solid wool buttons and hollow wool buttons, the RF coaxial connector has the advantages of good sealing performance, wide signal transmission bandwidth, high reliability and the ability to be solder-free interconnected with microstrip lines.
