Description

Technical Field

[0001] The utility model relates to the technical field of oil field measurement and control while drilling, in particular to a connector for oil field measurement and control while drilling. Background Art

[0002] The connector for oilfield measurement and control while drilling is a key component in the logging while drilling technology. It is responsible for transmitting the signals and power required by the measurement and control instruments during the drilling process. The connector is mainly used to connect the measurement and control instruments while drilling with the drill collar or other related equipment to achieve signal transmission and power supply. During the oilfield exploration, drilling and development process, the measurement and control instruments while drilling communicate with the ground control system through the connector, transmitting drilling parameters, formation information and other data in real time, providing a basis for geological guidance and drilling decisions.

[0003] In the process of measurement and control while drilling in oil fields, the main function of the connector is to connect the measurement and control while drilling instruments with downhole equipment such as drill collars, and to ensure that signals and data can be transmitted stably and reliably. Specifically, the connector realizes the composite transmission of electrical signals and power signals through its internal pins, cavities and other structures. At the same time, the connector also has components such as stabilizers and elastic contacts to ensure stability and reliability during the connection process.

[0004] However, when the contact surfaces of the plug and the connector slide against each other, the contact surface material will gradually wear due to the action of friction. Edge wear will cause the contact area inside the connector to decrease, thereby increasing the contact resistance, which will affect the signal transmission quality and may cause signal attenuation, distortion or interruption. Edge wear will cause the connection between the connector and the plug to become unstable, which may cause the connection to loosen or disconnect, thereby affecting the stability and reliability of the system. Utility Model Content

[0005] In view of the problem that the edge wear may cause the connection between the connector and the plug to become unstable, the present utility model is proposed.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a connector for drilling and control in oil fields, comprising a connecting plug, a fixed ring fixedly connected to the surface of the connecting plug, a clamping plate fixedly connected to one end of the fixing ring, a No. 2 spring fixedly connected to the inner bottom of the clamping plate, a No. 2 spring fixedly connected to the top of the No. 2 spring, a No. 2 clamping rod fixedly connected, a lap plate provided at the middle of the No. 2 clamping rod, a slide plate slidably connected to the outer surface of the No. 2 clamping rod, a No. 3 clamping rod and a No. 4 clamping rod connected to the clamping plate torsion spring are respectively provided on both sides of the No. 2 clamping rod, the top and bottom ends of the No. 3 clamping rod and the No. 4 clamping rod are rotatably connected to the No. 1 roller, and the inner top of the No. 2 clamping rod is rotatably connected to the No. 2 roller.

[0007] As a preferred solution of the connector for oilfield measurement and control while drilling of the utility model, a cable connector is inserted into the surface of the connecting plug, one end of the cable connector is electrically connected to a connecting cable, and a limit ring is fixedly connected to the surface of the connecting cable.

[0008] As a preferred solution of the connector for oil field measurement and control while drilling described in the utility model, a sliding groove is provided on the surface of the limiting ring, grooves are provided on both sides of the inner surface of the fixing ring, and a clamping rod No. 1 is sleeved on the inner surface of the groove.

[0009] As a preferred solution of the connector for oilfield measurement and control while drilling of the utility model, wherein: the surface of the No. 1 clamping rod is sleeved with a No. 1 spring, and one end of the No. 1 clamping rod is fixedly connected to a limit rod.

[0010] As a preferred solution of the connector for oilfield measurement and control while drilling of the utility model, the inner side wall of the groove is fixedly connected to a limiting block, and one end of the No. 1 clamping rod is fixedly connected to a limiting plate.

[0011] As a preferred solution of the connector for oilfield measurement and control while drilling of the utility model, the shape of the lap plate is trapezoidal, and the lap plate is overlapped on the upper surface of the slide plate.

[0012] Beneficial effects of the utility model:

[0013] 1. The utility model is provided with a No. 2 clamping rod, a No. 3 clamping rod, a No. 4 clamping rod and a connecting cable. When the No. 2 clamping rod, the No. 3 clamping rod and the No. 4 clamping rod are squeezed by the connecting cable and rotated outward to spread out, they can play the role of clamping the connecting cable, avoiding edge wear that may cause the contact area between the connector and the plug to be reduced, thereby affecting the quality of signal transmission. At the same time, it can ensure good contact, reduce signal attenuation, ensure the integrity and accuracy of the signal, and ensure a close fit between the connector and the plug to maintain a stable connection state.

[0014] 2. Connecting plug, cable connector, limiting ring and limiting rod. When the cable connector is plugged into the connecting plug, the limiting ring squeezes the limiting rod to clamp and lock it. The clamping and locking can ensure that the clamped connecting plug and fixing ring will not move or fall off during processing, transportation or storage, thereby greatly improving the overall stability. The stable clamping state helps to reduce material waste and processing errors caused by workpiece movement or falling off, thereby saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-3, which is the first embodiment of the utility model, provides a connector for oil field drilling measurement and control, including a connecting plug 1, a fixing ring 2 is fixedly connected to the surface of the connecting plug 1, a clamping plate 3 is fixedly connected to one end of the fixing ring 2, a No. 2 spring 4 is fixedly connected to the inner bottom of the clamping plate 3, a No. 2 clamping rod 5 is fixedly connected to the top of the No. 2 spring 4, a No. 2 clamping rod 5 is fixedly connected to the top, a lap plate 6 is provided in the middle of the No. 2 clamping rod 5, a slide plate 7 is slidably connected to the outer surface of the No. 2 clamping rod 5, a No. 3 clamping rod 8 and a No. 4 clamping rod 9 connected to the torsion spring of the clamping plate 3 are respectively provided on both sides of the No. 2 clamping rod 5, the top and bottom ends of the No. 3 clamping rod 8 and the No. 4 clamping rod 9 are rotatably connected to the No. 1 roller 10, the No. 2 clamping rod 5 The inner top is rotatably connected to the second roller 11, which fixes and clamps the connecting cable 13 to avoid edge wear of the connecting cable 13, which may cause the contact area between the connector and the plug to decrease, thereby affecting the quality of signal transmission. Avoiding wear can ensure good contact, reduce signal attenuation, and ensure signal integrity and accuracy. Reducing wear on the edge of the connecting cable 13 can extend its service life and reduce the frequency of replacement due to wear, thereby reducing maintenance costs. At the same time, edge wear may cause the connector to experience performance degradation or failure in harsh environments. Avoiding wear on the connecting cable 13 can improve the reliability of the connector and ensure that it can work normally in various environments.

[0026] Example 2

[0027] Reference Figure 1-4, which is the second embodiment of the present utility model, which is different from the first embodiment in that: a cable connector 12 is inserted into the surface of the connecting plug 1, one end of the cable connector 12 is electrically connected to a connecting cable 13, the surface of the connecting cable 13 is fixedly connected to a limiting ring 14, a sliding groove 15 is provided on the surface of the limiting ring 14, grooves 16 are provided on both sides of the inner surface of the fixing ring 2, a No. 1 clamping rod 17 is sleeved on the inner surface of the groove 16, a No. 1 spring 18 is sleeved on the surface of the No. 1 clamping rod 17, one end of the No. 1 clamping rod 17 is fixedly connected to a limiting rod 19, the inner side wall of the groove 16 is fixedly connected to a limiting block 20, one end of the No. 1 clamping rod 17 is fixedly connected to a limiting plate 21, the lap plate 6 is trapezoidal in shape, and the lap plate 6 is overlapped on the upper surface of the slide 7, which is convenient for cable connection The installation and disassembly of the head 12 and the connecting plug 1 enables the clamping lock to ensure that the clamped workpiece or article will not move or fall off during processing, transportation or storage, thereby greatly improving the overall stability. Through firm clamping and locking, the risk of accidents caused by movement or falling of the workpiece can be reduced, ensuring the safety of personnel and equipment. The detachable plug does not require the use of additional tools, and can be connected or disconnected with a simple plug-in operation, which greatly improves the convenience of use. The ease of installation and disassembly allows staff to complete the assembly and disassembly of the equipment more quickly, reducing the operating steps and time costs. At the same time, the convenient disassembly method allows staff to more easily access the interior of the equipment to perform necessary maintenance and inspections, thereby preventing potential safety hazards.

[0028] The working process of this utility model is as follows:

[0029] When the cable connector 12 and the connecting plug 1 are connected together, the staff can insert the cable connector 12 and the connecting plug 1 together. At the same time, the slide groove 15 in the limit ring 14 squeezes the limit rod 19, and the limit rod 19 squeezes the telescopic spring 18 backward. The limit block 20 prevents the No. 1 spring 18 from sliding out when moving backward, playing a limiting role, and the shape of the No. 1 clamping rod 17 is trapezoidal, and the limit rod 19 squeezes and rebounds into the slide groove 15, playing a clamping role. When the staff wants to pull the cable connector 12 out of the connecting plug 1, they can pull the limit plate 21, and the limit plate 21 moves in the groove 16, so as to cancel the clamping of the limit rod 19 on the limit ring 14. The cable connector 12 and the connecting plug 1 are easy to install or disassemble, which is convenient for the staff to use. The clamping lock can ensure that the clamped connecting plug 1 and the fixing ring 2 will not move or fall off during processing, transportation or storage, thereby greatly improving the overall stability. The stable clamping state helps to reduce material waste and processing errors caused by movement or falling of the workpiece, thereby saving costs.

[0030] The connecting cable 13 moves along the No. 1 roller 10 and the No. 2 roller 11. Since the connecting cable 13 itself has a certain weight, the connecting plate 6 squeezes the No. 2 spring 4 downward at the moment of clamping. The slopes on both sides of the connecting plate 6 facilitate the rolling of the No. 1 roller 10 on the No. 3 clamping rod 8 and the No. 4 clamping rod 9. The connecting cable 13 is placed on the No. 2 roller 11, pushing the No. 2 clamping rod 5 and the connecting plate 6 to descend in height, so that the No. 3 clamping rod 8 and the No. 4 clamping rod 9 are automatically reset toward the No. 2 clamping rod 5 by the elastic restoring force of the torsion spring, thereby causing the corresponding No. 1 roller 10 to squeeze and contact both sides of the connecting cable 13, avoiding wear on the edge of the connecting cable 13, which may cause the contact area between the connector and the plug to be reduced, thereby affecting the quality of signal transmission. At the same time, it can ensure good contact, reduce signal attenuation, ensure the integrity and accuracy of the signal, and ensure a close fit between the connector and the plug to maintain a stable connection state.

[0031] The remaining structures are the same as those of Example 1.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
