Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and in particular to an electrical connector for intelligent resilient metal-plastic thrust pads. Background Technology

[0002] Thrust bearings, also known as thrust plates, are used to balance the axial thrust of a rotor, establish the dead point of rotor expansion, and thus ensure that the axial clearance between moving and stationary parts is within the design range. Thrust bearings are widely used in steam turbines, water turbines, water pumps, and in the processing of mirror plates for hydro-generators and the grinding of old mirror plates. Existing bearing monitoring only monitors the temperature of a single bearing body, while intelligent elastic metal-plastic thrust bearings are equipped with multiple sensors to monitor parameters throughout their entire life cycle, such as oil film temperature, oil film thickness, oil inlet temperature, and friction and wear. With so many sensors, the electrical connections between them are particularly important. To ensure the electrical connector is safe and reliable and will not detach due to oil flow impact, anti-loosening and secure measures must be implemented. Based on this, an electrical connector is designed that provides a secure connection and is easy to install. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] In view of the problems existing in the above and / or existing electrical connectors for smart resilient metal-plastic thrust pads, the present invention is proposed.

[0005] Therefore, the problem that this invention aims to solve is that the electrical connectors in ordinary thrust bearings are easily dislodged by the impact of oil flow, making installation and replacement inconvenient.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an electrical connector for intelligent elastic metal-plastic thrust pads, comprising: a connecting assembly including a plug, a socket cooperating with the plug, a locking member disposed outside the plug, and an alignment member disposed inside the plug; and a fixing assembly including a telescopic member disposed outside the socket, a pushing member disposed at one end of the telescopic member, and a tensioning member disposed at one end of the pushing member.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides an electrical connector for a smart resilient metal-plastic thrust pad. The electrical connector for the smart resilient metal-plastic thrust pad includes a connecting component 100 and a fixing component 200. The connecting component 100 allows the electrical connector to be easily and quickly installed. The fixing component 200 then secures the electrical connector tightly within the mounting groove of the thrust pad.

[0034] Specifically, the connecting assembly 100 includes a plug 101, a socket 102 that mates with the plug 101, a locking member 103 disposed outside the plug 101, and an alignment member 104 disposed inside the plug 101. The socket 102 is partially disposed within a mounting groove in the thrust bearing to minimize the impact of oil flow. The locking member 103 primarily connects the plug 101 and the socket 102, while the alignment member 104 enables blind insertion, allowing direct insertion without manual alignment of the socket; alignment is achieved automatically while locking the plug 101 and socket 102.

[0035] Preferably, the fixing component 200 includes a telescopic member 201 disposed outside the socket 102, a pusher 202 disposed at one end of the telescopic member 201, and a tensioner 203 disposed at one end of the pusher 202.

[0036] In use, align the plug 101 with the socket 102, then rotate the locking member 103. As the locking member 103 rotates, the alignment member 104 automatically inserts the internal wire into the corresponding hole. At the same time, the locking member 103 also pushes the telescopic member 201 to move, which further causes the pushing member 202 to drive the tensioning member 203 to open, thereby firmly fixing the electrical connector in the mounting groove within the thrust bearing.

[0037] Example 2

[0038] Reference Figures 3-11 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the locking member 103 includes a rotating groove 103a disposed on the housing of the plug 101, and a sleeve 103b with one end disposed inside the rotating groove 103a. One end of the sleeve 103b protrudes and fits perfectly into the rotating groove 103a, so the connection between the sleeve 103b and the plug 101 is a rotatable connection. When the sleeve 103b is rotated, the plug 101 is not affected; the sleeve 103b has threads inside.

[0040] Preferably, the alignment member 104 includes serrations 104a disposed inside the sleeve 103b. The serrations 104a rotate as the sleeve 103b rotates.

[0041] Preferably, the alignment member 104 further includes a protrusion 104b disposed inside the housing of the plug 101, and a notch 104c disposed on the middle housing of the socket 102, the protrusion 104b and the notch 104c slidingly engaging. The plug 101 can only be correctly inserted into the socket 102 when the protrusion 104b is in the position of the notch 104c.

[0042] Preferably, the alignment member 104 further includes a striker 104d disposed inside the protrusion 104b, and a first spring 104e disposed at the end of the striker 104d. The protrusion 104b and the housing of the plug 101 have internal channels through which the striker 104d is installed, with a wedge-shaped opening at its end. The first spring 104e is a compression spring, with one end fixedly connected to the inner wall of the channel and the other end fixedly connected to the striker 104d, primarily serving a resetting function. The protrusion 104b contacts the socket 102 before the plug 101.

[0043] Preferably, the alignment member 104 further includes a connecting rod 104f disposed on the top of the firing pin 104d, and a locking block 104g disposed on the top of the connecting rod 104f. The bottom of the connecting rod 104f is also wedge-shaped, engaging with the opening of the firing pin 104d. When the firing pin 104d moves inward, the connecting rod 104f is compressed and lifted upward, thereby pushing the locking block 104g upward, engaging with the serrations 104a inside the sleeve 103b.

[0044] Preferably, the telescopic member 201 includes a telescopic block 201a disposed outside the housing of the socket 102, and a second spring 201b disposed at one end of the telescopic block 201a. The second spring 201b is a compression spring, and the telescopic block 201a will push the push rod 202a to move only when the second spring 201b is compressed to its shortest length.

[0045] Preferably, the pusher 202 includes a push rod 202a disposed outside the telescopic block 201a, and a movable ring 202b fixedly connected to the push rod 202a. The socket 102 has a thread on its exterior that mates with the internal thread of the sleeve 103b. A groove is formed in the middle of the thread on the exterior of the socket 102. The push rod 202a moves within the groove, and the movable ring 202b is fitted around the socket 102 and fixedly connected to the push rod 202a.

[0046] Furthermore, the tensioning member 203 includes a hinge support 203a disposed on the outside of the moving ring 202b and the housing of the socket 102, and a strut 203b cooperating with the hinge support 203a. The struts 203b are hinged in the middle of each other to form a scissor shape.

[0047] Furthermore, the tensioning member 203 also includes a support plate 203c disposed at the other end of the strut 203b, the support plate 203c being hinged to the strut 203b. The support plate 203c can be square or arc-shaped, depending on the shape of the inner wall of the mounting groove in the thrust bearing.

[0048] When in use, align the plug 101 with the socket 102, then rotate the sleeve 103b to make its internal thread engage with the external thread of the socket 102, and continue to rotate the sleeve 103b to drive the internal wire post of the plug 101 to gradually approach the internal wire hole of the socket 102. Because the plug 101 can only be properly connected when the protrusion 104b on the plug 101 is aligned with the notch 104c on the socket 102, when the protrusion 104b is not aligned with the notch 104c, that is, when the protrusion 104b hits other parts of the socket 102 except for the notch 104c, the striker 104d is compressed and retracts, and its other end pushes the locking block 104g upward in the direction shown in the figure. The locking block 104g engages with the serration 104a inside the sleeve 103b. Continuing to rotate the sleeve 103b will drive the plug 101 to rotate. When the striker 104d rotates to the position of the notch 104c, it loses compression and resets under the action of the first spring 104e. The locking block 104g falls back and disengages from the serration 104a of the sleeve 103b. Continuing to rotate the sleeve 103b will not drive the plug 101 to rotate together, thus realizing that the plug 101 and the socket 102 can be accurately connected by simply rotating the sleeve 103b. Additionally, it should be noted that the retractable length of the striking pin 104d is not less than the length of the sleeve 103b's forward rotation in one revolution. In extreme cases, the striking pin 104d rotates a full revolution before finding the notch 104c, thus preventing interference during movement. Furthermore, a spring can be installed at the position of the locking block 104g to facilitate its return. Once the plug 101 and socket 102 are correctly connected, the sleeve 103b continues to rotate, pressing the telescopic block 201a, which in turn presses the push rod 202a, pushing the moving ring 202b. As the moving ring 202b moves, the support rod 203b rotates, and the hinged support plate 203c expands outwards, pressing against the mounting groove inside the thrust bearing, thus ensuring the stability of the electrical connector. The entire device has a compact structure and operates smoothly, avoiding oil flow impact while simplifying the connection process.

[0049] 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 it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
