Description
Technical Field
[0001] This utility model relates to the field of push-pull self-locking connector technology, and in particular to a push-pull self-locking connector that is easy to install. Background Technology
[0002] Push-pull self-locking connectors are widely used in industrial automation, medical devices, and communication equipment due to their ease of operation and reliable connection. Traditional push-pull self-locking connectors typically employ an integral structure, with the internal conductive core and housing usually fixedly connected or assembled using complex tools. When the internal conductive core (such as pins or socket modules) wears down due to long-term use, or when different specifications of core need to be replaced according to the application scenario, the disassembly and replacement process is often very cumbersome, sometimes even requiring the entire connector to be scrapped. This not only increases equipment maintenance costs but also wastes resources.
[0003] Furthermore, when transmitting high currents, the contact points of the conductive core blocks in connectors generate significant heat. If this heat cannot be dissipated in time, it will cause the overall temperature of the connector to rise, accelerating the aging of internal components, increasing contact resistance, and even leading to connection failure or safety accidents. Some existing connectors with heat dissipation structures often have heat dissipation paths that are independent of the mechanical locking structure, resulting in limited heat dissipation efficiency and complex structures. It is difficult to achieve both rapid assembly and disassembly and efficient heat dissipation while maintaining a compact size.
[0004] Therefore, this application provides a push-pull self-locking connector that is easy to install to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a push-pull self-locking connector that is easy to install, so as to solve the problem that the connectors of the existing heat dissipation structure are difficult to achieve quick disassembly and efficient heat dissipation while ensuring a compact size.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A push-pull self-locking connector that is easy to install includes a male connector and a female connector. One end of the male connector is provided with a male core block. Positioning ears are symmetrically fixed on both sides of the male core block. Positioning grooves are opened on the inner walls of both sides of the male connector for the end of the positioning ear to be inserted. A button is elastically installed on the outer side of the male connector and placed in the positioning groove. The button abuts against the end of the positioning ear. One end of the female connector is provided with a female core block. Heat-conducting plates are symmetrically arranged on both sides of the female connector. The two heat-conducting plates surround the female core block. A positioning post extending out of the outer side of the female connector is elastically installed in the middle of the outer side of the heat-conducting plate. The inner wall of the male connector is provided with a positioning hole for the end of the positioning post to be inserted. A heat sink is fixed on the outer side of the male connector. A heat-conducting post inserted into the positioning hole is fixed in the middle of the heat sink. The end of the heat-conducting post is provided with a docking ball groove for the end of the positioning post to dock.
[0007] Optionally, the bottom sides of the button are symmetrically fixed with lugs, and a first spring is connected to the lugs and fixed to the top of the inner wall of the positioning groove.
[0008] Optionally, the first spring elastically abuts the button against the outside of the male connector.
[0009] Optionally, the heat-conducting plate is an arc-shaped plate, a fixing cylinder is fixed to the middle of the outer side of the heat-conducting plate, and a movable rod inserted into the fixing cylinder is fixed to the end of the positioning post.
[0010] Optionally, a second spring is fixed on the fixed cylinder, the second spring is sleeved on the movable rod, and elastically pushes the positioning pin outward.
[0011] Optionally, the end of the positioning post extending beyond the female connector is spherical.
[0012] Optionally, heat dissipation fins are fixed to the outer side of the heat sink.
[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, thanks to the cooperation of the male connector, female connector, female core block, male core block and button, the positioning ear can be easily pushed out of the positioning slot by pressing the button, which facilitates the disassembly and assembly of the male core block and is beneficial for later maintenance.
[0014] In the above solution, thanks to the cooperation of the positioning post, heat-conducting plate, heat sink, and heat-conducting post, the positioning post and positioning hole can be used to form a push-pull self-locking structure. At the same time, the heat-conducting plate can be used to conduct the heat at the female core block to the heat sink for heat dissipation, which helps to ensure the long-term operation of this connector.
[0015] In summary, this device not only facilitates the disassembly and assembly of the male core block, making maintenance easier, but also provides heat dissipation protection at the connection points, resulting in excellent overall performance. Attached Figure Description

[0025] like Figure 1-4 As shown, an embodiment of this utility model provides a push-pull self-locking connector that is easy to install, including a male connector 1 and a female connector 2. One end of the male connector 1 is provided with a male core block 4, which can be fitted with different numbers or specifications of pins according to circuit requirements. To achieve quick installation and fixation of the male core block 4, positioning ears 401 are symmetrically fixed on both sides, and positioning grooves 101 are correspondingly opened on both sides of the inner wall of the male connector 1 for the ends of the positioning ears 401 to be inserted. On the outer side of the male connector 1, corresponding to the position of each positioning groove 101, a button 5 is elastically installed. A portion of the button 5 extends into the positioning groove 101 and directly abuts against the end of the positioning ear 401 inserted therein. Specifically, protruding ears 501 are symmetrically fixed on both sides of the bottom of the button 5, and a first spring 502 is connected to the protruding ears 501. The other end of the first spring 502 is fixed to the top of the inner wall of the positioning groove 101. Under the preload of the first spring 502, the button 5 is continuously and elastically pressed against the outside of the male connector 1, leaving space for the positioning ear 401 to be inserted, so that pressing the button 5 can push out the positioning ear 4 to release the limit.
[0026] Therefore, when it is necessary to disassemble the male core block 4 for maintenance or replacement, the operator only needs to press the button 5 on the outside of the male connector 1. The button 5 moves inward against the force of the first spring 502, and its inner end pushes the end of the positioning ear 401 out of the positioning groove 101, thereby releasing the lock on the male core block 4. At this time, the male core block 4 can be easily removed from the tail of the male connector 1. The whole process does not require special tools and is simple and quick.
[0027] One end of the female connector 2 is provided with a female core block 3 that electrically engages with the male core block 4. Two heat-conducting plates 7 are symmetrically arranged on both sides of the internal cavity of the female connector 2. These two heat-conducting plates 7 together surround and enclose the female core block 3 to maximize the absorption of heat generated during operation. The heat-conducting plates 7 are preferably arc-shaped plates that match the outer contour of the female core block 3 to ensure good thermal contact. A positioning post 6 is elastically installed at the center of the outer side of each heat-conducting plate 7, with its end extending beyond the outer surface of the female connector 2. Specifically, a fixing cylinder 701 is fixed at the center of the outer side of the heat-conducting plate 7, and a movable rod 601 is fixed to the end of the positioning post 6. The movable rod 601 is inserted into the fixing cylinder 701 and can slide axially. A second spring 702 is fixed to the fixing cylinder 701 and sleeved on the outside of the movable rod 601. The preload of the second spring 702 continuously and elastically pushes the positioning post 6 outward from the female connector 2, ensuring that its end always maintains an outward extension tendency. To ensure smooth connection guidance and reliable locking, the end of the positioning post 6 extending beyond the female connector 2 is designed as a smooth spherical surface.
[0028] When the male connector 1 and the female connector 2 are inserted together, the inner wall of the male connector 1 applies pressure to the spherical end of the positioning post 6 on the female connector 2, forcing the positioning post 6 to retract inward against the force of the second spring 702 until the male and female connectors are fully inserted. At this time, the positioning post 6 is quickly ejected under the reset action of the second spring 702, and its end is precisely locked into the positioning hole 102 pre-drilled in the inner wall of the male connector 1, forming a reliable mechanical self-locking mechanism to prevent the two from accidentally disengaging.
[0029] To further improve heat dissipation performance, a heat sink 8 is fixed to the outside of the male connector 1. The heat sink 8 is preferably made of a material with good thermal conductivity, such as aluminum alloy. A heat-conducting post 801 is fixed in the middle of the heat sink 8. The heat-conducting post 801 is inserted into the wall of the male connector 1 and its end extends to the positioning hole 102 area. Of particular importance, a mating ball groove 802 is provided at the inward-facing end of the heat-conducting post 801 for the end of the positioning post 6 to mate with. When the connector is fully inserted, that is, when the positioning post 6 is engaged in the positioning hole 102, the spherical end of the positioning post 6 is also tightly embedded in the mating ball groove 802. This ingenious design optimizes the heat transfer path, so that the heat generated by the female core block 3 is first absorbed by the surrounding heat-conducting plates 7, then conducted through the positioning post 6 to the heat-conducting post 801, and finally efficiently transferred to the external heat sink 8 and dissipated into the air. To increase the heat dissipation area and accelerate heat dissipation, multiple parallel heat dissipation fins 803 can be further fixed to the outside of the heat sink 8.
[0030] In summary, this embodiment not only enables quick assembly and disassembly of the core conductive components through the cooperation of button 5 and positioning ear 401, facilitating later maintenance, but also creatively integrates the mechanical locking structure with the thermal management structure. The positioning post 6 simultaneously serves as a self-locking pin and a thermal bridge, efficiently dissipating internal heat to the external heat sink, ensuring the connector's operational stability and service life under long-term, high-current conditions. This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
