Technical Field
[0001] This application relates to the field of power electronic equipment technology, and in particular to a docking terminal structure and electrical equipment. Background Technology
[0002] Most current connectors are movable structures, which move with the cable when it is connected, making it impossible to fix the position and making it difficult to achieve fixed cable length and accurate positioning during maintenance.
[0003] Therefore, how to improve the connection stability of terminals is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the purpose of this application is to provide a terminal structure and electrical equipment to improve the connection stability and maintenance convenience of the terminals.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] A mating terminal structure for fixing to a target device includes a female connector with a slot for inserting a male connector; the female connector has a fixing part for engaging with a mounting hole on the target device, the fixing part including a backstop part, at least a portion of the fixing part passing through the mounting hole and being locked to the target device by the backstop part.
[0007] Preferably, in the above-described docking terminal structure, the fixing part includes a support shaft, and the anti-reverse part is disposed on the outer wall of the support shaft.
[0008] Preferably, in the above-described docking terminal structure, the anti-reverse portion is disposed around the circumferential outer wall of the support shaft and expands toward the end of the support shaft connected to the female head, and the outer diameter of the annular surface of the anti-reverse portion toward the female head is larger than the outer diameter of the mounting hole.
[0009] Preferably, in the above-described docking terminal structure, one or more of the anti-reverse portions are provided along the axial direction of the support shaft.
[0010] Preferably, in the above-described docking terminal structure, at least two fixing parts are provided on the same wall surface of the female head, and any two fixing parts are spaced apart.
[0011] Preferably, in the above-described docking terminal structure, the anti-reverse portion consists of a plurality of barbs evenly arranged circumferentially along the support axis.
[0012] Preferably, in the above-mentioned docking terminal structure, the support shaft is further provided with a limiting arm in the circumferential direction. The limiting arm corresponds one-to-one with the barb and is spaced apart from the barb. The limiting arm is used to cooperate with the barb to clamp the two sides of the mounting hole.
[0013] Preferably, in the above-described mating terminal structure, at least two of the slots are arranged in a single direction on opposite sides of the female head.

[0016] As can be seen from the above technical solution, the mating terminal structure provided in this application realizes the electrical connection of the cable by setting a slot for the male connector to be inserted. At the same time, a fixing part is set on the female connector to fix the position of the mating terminal structure on the target device.

[0024] The core of this application is to disclose a terminal structure and electrical equipment to improve the connection stability and maintenance convenience of the terminals.
[0025] To enable those skilled in the art to better understand the present application, embodiments of the present application will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model described in the claims. Additionally, the complete content of the structures represented in the following embodiments is not limited to those necessary for the solution of the utility model described in the claims.
[0026] like Figure 1 and Figure 2 As shown, this disclosure provides a docking terminal structure that can be fixedly installed on a target device 40, thereby achieving precise positioning and quick maintenance. Specifically, the docking terminal structure includes a female connector 10 that provides electrical connection relay, and the female connector 10 is provided with slots 110 for male connectors 30 to be inserted. It should be noted that, considering the bridging requirements of commonly used female connectors 10, the female connector 10 is specifically provided with at least two slots 110, and each slot 110 is sealed and conductive inside the female connector 10. The slots 110 are used for inserting and docking cables with male connectors 30, so that any two male connectors 30 inserted into the same slot 110 of the female connector 10 can achieve electrical connection. The provision of at least two slots 110 can provide space for the insertion of multiple cables and cable insertion for different connection directions.
[0027] Furthermore, such as Figure 1 and Figure 3 As shown, in addition to fulfilling the electrical connection requirements of the cable, the female connector 10 is also provided with a fixing part 20 to mate with the mounting hole 410 on the target device 40, thereby achieving fixation at the position of the mounting hole 410. The fixing part 20 can be an assembled structure, such as a threaded connection or a bolt connection, and can also be integrally formed with the female connector 10. The fixing part 20 includes a backstop 210, which is provided on the fixing part 20 and is used to allow the fixing part 20 to move unidirectionally in the mounting hole 410, preventing the fixing part 20 from reversing and coming off. Figure 3As shown, when the fixing part 20 is connected to the mounting hole 410 on the target device 40, at least a portion of its area passes through the mounting hole 410, and a backstop part 210 is provided on the area passing through the mounting hole 410, so that the backstop part 210 and the female head 10 are respectively located on opposite sides of the mounting hole 410, and the anti-reverse disengagement function of the backstop part 210 can lock the mating terminal structure at the mounting hole 410 position of the target device 40.
[0028] It should be noted that the anti-detachment effect is achieved through the structural arrangement of the fixing part 20 and the anti-reverse part 210, and the fact that the anti-reverse part 210 passes through the mounting hole 410. The mating terminal structure can be conveniently pressed into the mounting hole 410 by pressing the portion of the fixing part 20 with the anti-reverse part 210. This anti-detachment effect of the anti-reverse part 210 locks the mating terminal structure in the mounting hole 410 position without the need for other structural components. This results in low production costs and convenient operation. Based on this, the mating terminal structure has fixed mounting points on the target device 40. When operators perform cable insertion, removal, replacement, and maintenance operations, they can accurately locate the mating terminal structure and operate at the corresponding positions. Simultaneously, cables electrically connected to the same mating terminal structure can be produced with the cable length determined by the mounting hole 410 position on the target device 40, avoiding excessive redundancy after electrical connection, improving the overall aesthetics of the wiring structure, and reducing production and wiring costs.
[0029] Considering the convenience of production and installation, the mating terminal structure provided in this disclosure includes a fixing part 20 comprising a support shaft 220. The support shaft 220 is disposed on one side wall of the female head 10 and extends outwards. A check part 210 is disposed on the outer wall of the support shaft 220 and extends outwards from the center of the support shaft 220, also based on the outer wall of the support shaft 220. It should be noted that the shaft structure facilitates demolding during the integral molding process and has a clearly protruding structure, enabling operators to accurately mate it with the mounting hole 410. The anti-reverse part 210 is designed as a protruding structure based on the outer wall of the support shaft 220, which can achieve a better anti-reverse effect and reduce the overall material consumption. It should be noted that the function of the anti-reverse part 210 is to prevent it from coming out after passing through the mounting hole 410 by using its larger outer diameter structure compared to the mounting hole 410. Therefore, it needs to be in a sufficiently expanded outer diameter state to achieve the anti-reverse effect. Since the anti-reverse part 210 is set on the outer wall of the support shaft 220 rather than at the end of the support shaft 220, it can utilize part of the volume of the support shaft 220 and be set based on the outer diameter of the support shaft 220. It has lower material requirements when meeting the outer diameter expansion requirements, which can reduce material costs in the process of mass production of the docking terminal structure as a standard part.
[0030] Based on the above embodiments, in some embodiments of this disclosure, such as Figure 4 As shown, the anti-reverse part 210 is arranged around the outer wall of the support shaft 220 in the circumferential direction and is fixed to the support shaft 220 in a ring structure. It should be noted that the ring structure of the anti-reverse part 210 can ensure that there is an anti-reverse structure at any position on the outer periphery of the support shaft 220, so that the mating terminal structure can maintain a stable locking base at any position of the mounting hole 410, thereby reducing the risk of the mating terminal structure coming off. In order to facilitate the installation of the fixing part 20 and the mounting hole 410, the anti-reverse part 210 is also provided with a guide structure. That is, the anti-reverse part 210 is an expanded structure facing the end of the support shaft 220 connected to the female head 10, such as a conical or frustum structure. When the anti-reverse part 210 is conical, the bottom surface of its conical structure faces the female head 10 and is set through the mounting hole 410 through the tip of the conical structure. When the anti-reverse part 210 is frustum structure, the larger side of its circular surface faces the female head 10, while the smaller side of its circular surface is set through the mounting hole 410. It should also be noted that the outer diameter of the annular surface of the anti-reverse part 210 facing the female head 10 is larger than the outer diameter of the mounting hole 410. The anti-reverse part 210 is usually made of plastic material with a certain degree of flexibility. Under the pressure of the operator, it can pass through the mounting hole 410 through a certain degree of deformation and the guiding effect of its guiding structure. At the same time, the anti-reverse part 210 that has passed through the mounting hole 410 will return to its original structure. Then, through its annular surface facing the female head 10, it fits and abuts against the side of the mounting hole 410 facing away from the female head 10, so that the mating terminal structure is locked in the position of the mounting hole 410 and the mating terminal structure is fixed on the target device 40.
[0031] Furthermore, it should be noted that in this disclosure, one or more anti-reverse parts 210 are provided in the axial direction of the support shaft 220. A single anti-reverse part 210 can reduce the length requirement of the support shaft 220, thereby saving material consumption for the support shaft 220 and the anti-reverse part 210. It also has a more convenient installation process and is suitable for working conditions where the cable connection strength requirement is not high and the mating terminal structure is not easy to come out, such as indoor cable connection and working conditions where the equipment is in a stable state. The structure of multiple anti-reverse parts 210 can provide more layers of anti-dislodgement insurance for the support shaft 220 and the mating terminal structure. Multiple anti-reverse parts 210 are all set through the mounting hole 410 so that when a single anti-reverse part 210 comes out and fails, the remaining anti-reverse parts 210 can still satisfy the fixation of the mating terminal structure at the position of the mounting hole 410. It is suitable for cable working conditions where electrical connection is achieved through the mating terminal structure are complex and there is a risk of shaking, such as outdoor wind conditions and connection conditions where equipment is frequently moved.
[0032] Furthermore, in this disclosure, a single fixing part 20 can be provided, and the single fixing part 20 is positioned at a midpoint on one side of the female head 10 to achieve a more uniform connection and avoid the risk of the female head 10 wobbling. In other embodiments, multiple fixing parts 20 can also be provided, with multiple fixing parts 20 arranged in pairs at intervals to independently handle multiple areas and meet complex force requirements, avoiding the problem of a single fixing part 20 being unstable. For at least two fixing parts 20, they are symmetrically arranged on the same wall surface of the female head 10 to provide a stable connection effect.
[0033] It should be noted that the female connector 10 can also be provided with different combinations of fixing parts 20 on different side walls. For example, a single fixing part 20 can be provided on one side wall, while two fixing parts 20 can be provided on the adjacent side wall. Even three fixing parts 20 can be provided on the opposite side wall. The positions of the fixing parts 20 on each side wall can be set so that the single mating terminal structure can meet the different mounting hole 410 requirements on the target device 40, thereby improving the versatility of the mating terminal structure.
[0034] Based on the above embodiments, for the female head 10 structure having multiple fixing parts 20, such as Figure 5 As shown, the anti-reverse part 210 on its support shaft 220 can be a barb 230 structure, with several barbs 230 evenly arranged along the circumference of the support shaft 220. It should be noted that compared with the annular anti-reverse part 210 structure in the aforementioned embodiment, the anti-disengagement capability of the barb 230 structure is worse, but it has lower material consumption. For example, only two barbs 230 need to be symmetrically arranged on a single support shaft 220 to achieve anti-reverse, and it is easy to manufacture. Therefore, the anti-reverse part 210 of the barb 230 structure is usually set on the female head 10 structure with multiple fixing parts 20, so as to balance the anti-reverse effect of the barb 230 by adding fixing parts 20, and obtain a simpler installation requirement than the annular anti-reverse part 210.
[0035] Furthermore, it should be noted that the anti-reverse part 210 of the barb 230 structure and the annular structure can also be set on the same side wall of a single female head 10, so as to improve the anti-disengagement effect of the docking terminal structure through multiple anti-reverse methods; and preferably, for the anti-reverse part 210 of the annular structure, its corresponding mounting hole 410 is a round hole structure, while for the anti-reverse part 210 of the barb 230 structure, its corresponding mounting hole 410 is a square hole structure, so that the anti-reverse part 210 can give full play to the anti-disengagement advantages of different structures, and provide greater freedom for the setting of the mounting hole 410 on the target device 40.
[0036] To further optimize the above technical solution, the docking terminal structure provided in this disclosure also has a limiting arm 240 in the axial direction of the support shaft 220. The limiting arm 240 is configured in a one-to-one correspondence with the barb 230, that is, each barb 230 has a corresponding limiting arm 240, and each limiting arm 240 is spaced apart from its corresponding barb 230. When the docking terminal structure is connected at the mounting hole 410, the barb 230 passes through the mounting hole 410 and is located on opposite sides of the mounting hole 410 with the female head 10, while the limiting arm 240 is located on the same side of the mounting hole 410 with the female head 10. At the same time, the limiting arm 240 and the barb 230 cooperate to clamp the two sides of the mounting hole 410, thereby locking the position of the female head 10 in the axial direction of the support shaft 220 and improving the setting stability of the docking terminal structure.
[0037] Furthermore, considering common cable connection requirements, in this disclosure, at least two slots 110 on the female connector 10 are disposed on opposite sides of the female connector 10 along the first direction, so that when two cables are extended and connected in the first direction, as... Figure 1 As shown, the first direction can be the length direction of the female head 10, so that the slot 110 has a deeper setting depth and a more stable insertion effect; the mating terminal structure can realize wiring and avoid cable bending, improving the aesthetics of the cable connection.
[0038] Meanwhile, the mating terminal structure can be provided with slots 110 on all four side walls of the female head 10 circumferentially upward to meet the cable wiring requirements under different working conditions, and can ensure that no cable bends occur at each connection point, thereby improving the stability of the electrical connection.
[0039] Furthermore, in this disclosure, the female connector 10 has a slot 110 located at a position where it contacts the male connector 30, and a serrated limiting part 120 is also provided in the contact area with the male connector 30. The male connector 30 is provided with a corresponding serrated structure to engage with the slot 110. The serrated limiting part 120 can be provided around the connection position or only a sidewall can be provided. Both can achieve accurate docking between the male connector 30 and the female connector 10, thereby reducing the difficulty of wiring and improving the stability of the wiring.
[0040] Furthermore, this disclosure also provides an electrical device that includes the mating terminal structure provided in any of the above embodiments. It should be noted that since the mating terminal structure has the technical effects provided in any of the above embodiments, the electrical device also has the above technical effects, which will not be repeated here.
