Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically a compressor lead assembly. Background Technology

[0002] The compressor lead assembly is a crucial component connecting the compressor to external circuitry and is widely used in refrigeration equipment and other applications. It ensures a stable conductive connection between the compressor's internal motor and the external power source, guaranteeing orderly current transmission and playing a vital role in the connection and conduction of the compressor's normal operation.

[0003] Utility model patent CN220021717U discloses a lead-end socket assembly and a compressor. This assembly includes a wiring cover mounted on the compressor's upper cover; a terminal post mounted on the wiring cover, with its insertion port extending into the compressor; and a motor lead-end socket with a matching insertion hole for the terminal post. An annular protrusion surrounds the insertion hole. The terminal post engages with the insertion hole of the motor lead-end socket, and the annular protrusion closes with the wiring cover to form a sealed space. When the motor lead-end socket is inserted into the terminal post on the wiring cover inside the compressor, the annular protrusion closes with the wiring cover, creating a sealed space. This seals the terminal post from the compressor's interior, preventing impurities from being ejected from the compressor during operation and accumulating on the terminal post surface, thus eliminating the risk of short circuits and fires caused by impurities accumulating on the terminal post surface.

[0004] The motor lead socket assembly and compressor are connected only through a plug-in fit and an interference fit between the annular boss and the terminal cover, without a dedicated locking mechanism to secure the connection. During compressor operation, vibration and other factors may cause relative displacement between the motor lead socket and the terminal cover, affecting the stability of the connection and even leading to loosening or detachment, thus affecting conductivity. Therefore, we propose a compressor lead assembly. Utility Model Content

[0005] The purpose of this invention is to provide a compressor lead assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A compressor lead assembly includes a compressor body with a lead assembly mounted on the compressor body. The lead assembly includes a mounting base installed on the outer shell of the compressor body and a terminal block inserted into the top of the mounting base. The top of the mounting base has a insertion cavity, and the bottom of the insertion cavity has several metal terminals embedded therein. The bottom of the terminal block has a protrusion, and the bottom surface of the protrusion has several wiring holes corresponding to the terminals. The cavity wall of the insertion cavity has several side grooves along its circumference, and the side grooves have locking claws. The inner surface of the top of the locking claw has a protruding block, and the outer circumferential surface of the protrusion has a positioning ring groove corresponding to the position of the protrusion. The top of the mounting base has a protruding edge, and a movable sleeve and a spring are fitted on the outside of the mounting base, with the bottom of the movable sleeve abutting against the top of the spring.

[0008] Preferably, the compressor body has a mounting base for mounting the lead wire assembly on its outer casing, and the bottom end of the fixing base is threaded onto the mounting base;

[0009] In this configuration, the threaded connection ensures a secure installation of the mounting bracket and facilitates disassembly and maintenance.

[0010] Preferably, the bottom end of the locking claw is an integral structure with the fixing base, and the locking claw can undergo elastic deformation;

[0011] In this design, the integrated structure enhances connection strength, and elastic deformation ensures smooth locking and unlocking.

[0012] Preferably, the movable sleeve has a hollow cylindrical structure and can move along the axial direction of the fixed seat on the outside of the fixed seat. Under the action of the spring force, the movable sleeve is pressed against the bottom end of the protrusion by the spring, and at this time the movable sleeve covers the locking claw.

[0013] In this configuration, the hollow structure is fitted with a fixed base, and the spring-assisted movable sleeve stably covers the locking pawl to prevent accidental deformation.

[0014] Preferably, when the movable sleeve moves toward the bottom of the fixed base, the movable sleeve moves away from the locking pawl;

[0015] In this setting, with the movable sleeve moved away, it is easier to operate the locking claw to remove the terminal block.

[0016] Preferably, the outer peripheral surface of the movable sleeve is provided with a plurality of protruding paddles along its circumference, from which the movable sleeve can be paddled;

[0017] In this setting, the lever provides a convenient point of force for moving the movable sleeve, making operation easier.

[0018] Preferably, the terminal block has a foolproof groove at its head position, and the top of the protruding edge has a foolproof claw corresponding to the position of the foolproof groove.

[0019] In this setting, the anti-foolproof groove and anti-foolproof protrusion work together to prevent incorrect insertion direction of the terminal block.

[0020] Preferably, an annular groove is formed at the outer peripheral edge of the bottom surface of the protrusion, and a sealing ring made of rubber material is embedded in the annular groove. The bottom end of the sealing ring protrudes from the bottom surface of the protrusion. When the protrusion is inserted into the insertion cavity, the sealing ring is deformed by the bottom of the insertion cavity and the protrusion.

[0021] In this configuration, the sealing ring, after being compressed and deformed, can seal the gap between the protrusion and the insertion cavity, preventing external impurities from entering.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This compressor lead assembly features a locking claw within the side groove of the fixed base. The protrusion at the tip of the locking claw engages with the positioning ring groove on the outer periphery of the terminal block's protrusion, effectively locking the connection between the fixed base and the terminal block. Simultaneously, the movable sleeve, under the action of a spring, covers the locking claw, preventing accidental deformation of the locking claw that could lead to locking failure. This ensures the stability of the connection between the fixed base and the terminal block, preventing loosening or detachment due to vibration or other factors, and guaranteeing stable conductivity.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Please see Figures 1-5 A compressor lead wire assembly includes a compressor body 100, on which a lead wire assembly 200 is mounted. The compressor body 100 provides a mounting base for the lead wire assembly 200, ensuring that the lead wire assembly 200 can be stably assembled on the compressor. A mounting seat for mounting the lead wire assembly 200 is provided on the outer casing of the compressor body 100. The mounting seat provides a specific position for fixing the lead wire assembly 200, ensuring accurate installation. The lead wire assembly 200 includes a fixing seat 210 mounted on the outer casing of the compressor body 100 and a terminal block 220 inserted into the top of the fixing seat 210. The fixing seat 210 and the terminal block 220 cooperate to connect and fix the lead wire, and the fixing seat 210 provides insertion support for the terminal block 220. The bottom end of the fixing seat 210 is threadedly connected to the mounting seat. The threaded connection allows the fixing seat 210 to be securely mounted on the mounting seat and facilitates disassembly and maintenance.

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, in this utility model, the top of the fixing base 210 is provided with a plug-in cavity 211, which provides an insertion space for the protrusion 221 of the terminal block 220, ensuring a smooth plug-in process; the bottom of the plug-in cavity 211 is embedded with a number of metal terminals 212, which have good conductivity and can realize effective current transmission; the bottom of the terminal block 220 is provided with a protrusion 221, which can be inserted into the plug-in cavity 211 to achieve the initial positioning of the terminal block 220 and the fixing base 210; the bottom surface of the protrusion 221 is provided with a number of wiring holes 2211 that correspond one-to-one with the terminals 212, which ensures that the terminals 212 can be accurately inserted and ensures the accuracy of the conductive connection.

[0035] like Figure 3 and Figure 4 As shown, specifically, the cavity wall of the insertion cavity 211 is provided with several side grooves 213 along its circumference. The side grooves 213 provide installation space for the locking claws 214, allowing the locking claws 214 to move within them. The locking claws 214 are installed inside the side grooves 213 and can undergo elastic deformation, providing a basis for subsequent locking with the positioning ring groove 222. The inner surface of the top of the locking claw 214 is provided with a protruding protrusion 2141, which can be engaged with the positioning ring groove 222 to lock the fixing seat 210 and the terminal block 220. A positioning ring groove 222 corresponding to the position of the protrusion 2141 is formed on the outer peripheral surface of 21. The positioning ring groove 222 cooperates with the protrusion 2141 to provide a specific position for locking and ensure the locking effect. The bottom end of the locking claw 214 is integrally formed with the fixed seat 210. The integral structure enhances the connection strength between the locking claw 214 and the fixed seat 210, making the locking claw 214 less prone to breakage during deformation. The locking claw 214 can undergo elastic deformation. The elastic deformation characteristic allows the locking claw 214 to open outward when the protrusion 221 is inserted and to reset after insertion to achieve locking.

[0036] like Figure 3 and Figure 4As shown, the top of the fixed base 210 is provided with a protruding edge 215, which can limit the movable sleeve 216 and prevent the movable sleeve 216 from moving excessively upward under the action of the spring 217. The movable sleeve 216 and the spring 217 are sleeved on the outside of the fixed base 210. The movable sleeve 216 can cover the locking pawl 214, and the spring 217 provides elastic force to the movable sleeve 216, so that the movable sleeve 216 can stably cover the locking pawl 214. The bottom end of the movable sleeve 216 abuts against the top end of the spring 217. This connection method allows the elastic force of the spring 217 to be effectively transmitted to the movable sleeve 216. The movable sleeve 216 has a hollow cylindrical structure. The hollow structure allows the movable sleeve 216 to be fitted onto the outside of the fixed base 210 and move axially. The movable sleeve 216 can move along the axial direction of the fixed base 210 on the outside of the fixed base 210. The axial movement characteristic allows the movable sleeve 216 to move away from or cover the locking claw 214 as needed. Several protruding paddles 2161 are provided on the outer peripheral surface of the movable sleeve 216. The paddles 2161 provide a force point for moving the movable sleeve 216, making it convenient for the operator to move the movable sleeve 216. The movable sleeve 216 can be moved from the paddles 2161, and the position of the movable sleeve 216 can be easily controlled by moving the paddles 2161. Under the elastic force of spring 217, the movable sleeve 216 is pressed against the bottom end of the protruding edge 215. At this time, the movable sleeve 216 covers the locking pawl 214. The covered state can prevent the locking pawl 214 from being accidentally touched and deformed, ensuring a stable locking effect. When the movable sleeve 216 moves towards the bottom of the fixed base 210, the movable sleeve 216 moves away from the locking pawl 214. The moved-away state facilitates the operation of the locking pawl 214 and the disassembly of the terminal block 220.

[0037] like Figure 3 and Figure 5 As shown, in addition, a foolproof groove 223 is provided at the head position of the terminal block 220, and a foolproof claw 2151 corresponding to the position of the foolproof groove 223 is provided at the top of the protruding edge 215. The foolproof groove 223 and the foolproof claw 2151 cooperate to prevent the terminal block 220 from being inserted in the wrong direction, and ensure that the terminal post 212 and the terminal hole 2211 are accurately connected.

[0038] like Figure 5As shown, it is worth noting that an annular groove is provided at the outer peripheral edge of the bottom surface of the protrusion 221. A sealing ring 224 made of rubber material is embedded in the annular groove. The annular groove provides an installation position for the sealing ring 224. The rubber material has good elasticity, which enables the sealing ring 224 to achieve a sealing function. The bottom end of the sealing ring 224 protrudes from the bottom surface of the protrusion 221. When the protrusion 221 is inserted into the insertion cavity 211, the sealing ring 224 is squeezed and deformed by the bottom of the insertion cavity 211 and the protrusion 221. The deformed sealing ring 224 can fill the gap between the protrusion 221 and the insertion cavity 211, thereby achieving a sealing function and preventing external dust, moisture, etc. from entering the insertion cavity 211.

[0039] In this embodiment, when using the compressor lead assembly, firstly, the anti-misalignment groove 223 and the anti-misalignment claw 2151 are engaged to align the protrusion 221 of the terminal block 220 with the insertion cavity 211 of the fixing base 210, preparing for insertion; then, the protrusion 221 is inserted into the insertion cavity 211. During this process, the locking claw 214 undergoes elastic deformation due to the compression of the protrusion 221, and the protrusion 2141 moves outward with the locking claw 214. At the same time, the sealing ring 224 is compressed and deformed to achieve a seal; then, after the protrusion 221 is fully inserted, the locking claw 214 returns to its original position, and the protrusion 2141 moves outward with the locking claw 214. 2141 is inserted into the positioning ring groove 222, completing the locking of the fixed seat 210 and the terminal block 220. At this time, the terminal 212 is inserted into the wiring hole 2211 to achieve conductive connection. The movable sleeve 216 is pressed against the bottom of the protrusion 215 and covers the locking claw 214 under the action of the spring 217. Finally, if disassembly is required, the movable sleeve 216 is pushed down by the toggle block 2161 to move the movable sleeve 216 away from the locking claw 214. Then, the locking claw 214 is pulled outward to make the protrusion 2141 disengage from the positioning ring groove 222, so that the terminal block 220 can be pulled out from the fixed seat 210.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
