Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a threaded rotatable connector. Background Technology

[0002] Connectors are a common electronic component in electronic engineering. Their function is to connect circuits and transmit electrical energy or signals. One end of the connector is connected to two parts of the circuit, and when the connector is plugged in, the two parts of the circuit are connected to each other.

[0003] The connector plug with application number CN202321789845.4 has several sets of pins installed on one side, and a socket with matching holes for the pins. A rotating locking mechanism is symmetrically arranged on both sides of the connector plug. The rotating locking mechanism includes an anti-slip handle, with a rotating rod installed at one end of the handle and a locking rod at the other end. The locking rod is located inside a circular groove in the socket. A limit block is installed on one side of the circular groove, and the limit block has a through groove that matches the rotating rod and the locking rod. This connector plug, in this device, addresses the problem of insecure connections or inconvenient separation during socket connection. By symmetrically arranging the rotating locking mechanism on both sides of the connector plug, the locking rod in the rotating locking mechanism can engage with the circular groove in the socket. Simultaneously, the rotating locking mechanism can be removed from the socket through the through groove in the limit block, allowing the connector plug to be separated from the socket.

[0004] The device has a structure that facilitates separation. However, during oilfield drilling, the probe is often connected by a connector plug at one end and a connector socket at the other. The probe needs to be rotated when connected, but the connector cannot rotate with the probe when it is connected, which affects the connection and electrical contact of the connector.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing threaded rotatable connector structure. Utility Model Content

[0006] The purpose of this utility model is to provide a threaded rotatable connector to solve the problem mentioned in the background art that, during oilfield drilling and testing, one end of the probe is often equipped with a connector plug and the other end with a connector socket. When the probe needs to be rotated for connection, the connector cannot rotate with the probe during connection and mating, thus affecting the connection and electrical contact of the connector.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a threaded rotatable connector, comprising a socket body, a contact ring, contact solder feet, a plug body, a front insulator, a rear insulator, a movable contact, a fixed contact, a spring, and a retaining ring; the socket body has a contact ring fixedly connected to its inner side; the contact solder feet are fixedly installed inside the socket body; the plug body is located on the right side of the socket body; the front insulator is fixedly installed inside the plug body; the rear insulator is fixedly installed inside the plug body; the movable contact is slidably connected to the inside of the plug body; the fixed contact is fixedly installed inside the plug body; the spring has its two ends connected to the movable contact and the fixed contact respectively; and the retaining ring is installed inside the plug body.

[0008] Preferably, the contact ring and the contact weld foot are integrally stamped; in this structure, the contact ring and the contact weld foot 3 are connected or can be integrally stamped.

[0009] Preferably, one end of the movable contact extends into the inside of the fixed contact; in this structure, the one end of the movable contact extending into the inside of the fixed contact mainly serves a guiding function.

[0010] Preferably, the movable contact and the fixed contact form an elastic structure through a spring; in this structure, the movable contact and the fixed contact form an elastic structure through a spring. The spring is initially in a compressed state, the movable contact is pushed back by the spring, and the front insulating member supports it and keeps it stationary.

[0011] Preferably, the fixed contact is fixed by a front insulator and a rear insulator to prevent axial movement.

[0012] Preferably, the front insulator, rear insulator, movable contact, fixed contact and spring are assembled in sequence and then fixed to the inside of the plug body by retaining ring.

[0013] Preferably, the socket body has an external thread on its outer side, and the plug body has an external thread on its inner side, and the socket body and the plug body are threadedly connected; this structure has an external thread on the socket body and an external thread on the plug body for connection.

[0014] Compared with the prior art, the beneficial effect of this utility model is that the threaded rotatable connector:

[0015] When the connector is engaged, the internal thread of the socket passes through the external thread of the plug and screws into the inside of the plug body to achieve a threaded connection. When screwing in, when the movable contact in the plug body touches the contact ring in the socket body, the movable contact compresses the spring and retracts backward. At the same time, the head of the movable contact can move circumferentially along the surface of the contact ring until the connector plug body and the socket body are connected and locked. When the connector is disengaged, the same principle applies. Therefore, the connector plug body and the socket body can be rotatably connected, so that the connector can rotate with the probe during connection and engagement without affecting the connector connection and electrical contact.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a technical solution: a threaded rotatable connector, comprising:

[0022] Example 1: As Figures 1-3 The present invention provides a technical solution: a threaded rotatable connector, comprising: a socket body 1, a contact ring 2, contact solder feet 3, a plug body 4, a front insulator 5, a rear insulator 6, a movable contact 7, a fixed contact 8, a spring 9, and a retaining ring 10. The socket body 1 has a contact ring 2 fixedly connected to its inner side; the contact solder feet 3 are fixedly installed inside the socket body 1; the plug body 4 is located on the right side of the socket body 1; the front insulator 5 is fixedly installed inside the plug body 4; the rear insulator 6 is fixedly installed inside the plug body 4; and the movable contact 7 is slidably connected inside the plug body 4.

[0023] Fixed contact 8 is fixedly installed inside the plug body 4; spring 9 is connected at both ends to movable contact 7 and fixed contact 8 respectively; retaining ring 10 is installed inside the plug body 4.

[0024] The contact ring 2 and the contact welding foot 3 are integrally stamped; one end of the movable contact 7 is inserted into the inside of the fixed contact 8; the movable contact 7 and the fixed contact 8 form an elastic structure through the spring 9; the fixed contact 8 is fixed by the front insulator 5 and the rear insulator 6 and cannot move axially; the front insulator 5, the rear insulator 6, the movable contact 7, the fixed contact 8 and the spring 9 are assembled in sequence and then fixed to the inside of the plug body 4 by the retaining ring 10; the socket body 1 has an external thread on the outside and the plug body 4 has an external thread on the inside, and the socket body 1 and the plug body 4 are connected by threads;

[0025] When the connectors are engaged, the internal thread of the socket body 1 passes through the external thread of the plug body 4 and screws into the plug body, achieving a threaded connection. During this screwing-in process, when the movable contact 7 in the plug body 4 encounters the contact ring 2 in the socket body 1, the movable contact 7 compresses the spring 9 and retracts backward. Simultaneously, the head of the movable contact 7 can move circumferentially along the surface of the contact ring 2 until the connector plug body 4 and socket body 1 are locked together. The same principle applies when the connectors are disengaged. Therefore, the connector plug body 4 and socket body 1 can be rotatably connected.
