Description

Technical Field

[0001] This utility model relates to the field of power connector technology, and in particular to a power connector that is easy to fix. Background Technology

[0002] In the field of modern electronic equipment, power connectors, as key components for power transmission, are widely used in various electrical equipment, industrial control systems, communication equipment, and consumer electronics products.

[0003] Currently, the basic structure of existing power connectors typically consists of two parts: a male connector and a female connector. Stable power transmission is achieved through the precise mating of the male and female connectors. In use, the user simply inserts the plug at one end of the power cord into the socket of the corresponding device to establish an electrical connection and supply power to the device.

[0004] However, existing power connectors, whether female or male, do not have a fixing structure to be fixed on the connecting plate (such as the equipment housing, circuit board, etc.). After insertion, most power connectors are suspended in the air. Under mechanical vibration, external force pulling or frequent movement, other parts of the power connector may collide, causing it to be subjected to external impact. This can easily cause the power connector to detach, resulting in the equipment being unable to supply power normally and affecting the normal use of the equipment.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] In one embodiment of this utility model, such as Figure 1-5 As shown, a power connector for easy fixation is provided, including a female connector 10 and a male connector 20. The female connector 10 has three sets of parallel-distributed insertion holes 11. Fixing components 30 for fixing to a connecting plate are provided on both sides of the female connector 10. The male connector 20 has three sets of parallel-distributed insertion tips 21, each corresponding to one of the insertion holes 11, and the insertion tips 21 can be inserted into or detached from the insertion holes 11. A locking component 40 for stable connection is provided between the female connector 10 and the male connector 20.

[0038] By setting up the fixing component 30, which connects to the connecting plate via locking screws or snap-fit ​​rods, a stable connection with the equipment connecting plate is achieved. This avoids the problem of the female connector 10 and male connector 20 becoming loose or detached due to mechanical vibration, external pulling force, or equipment movement, ensuring the long-term stable operation of the power connector. Simultaneously, the locking component 40 added between the female connector 10 and male connector 20 allows them to automatically lock together through elastic deformation after insertion, further preventing accidental disengagement due to vibration or accidental contact.

[0039] Preferably, the fixing assembly 30 includes an outwardly extending fixing block 31 and a fixing member 32. The fixing block 31 is located on one side of the female connector 10. The top of the fixing block 31 has a downwardly recessed limiting portion, and the center of the fixing block 31 has a through hole for one end of the fixing member 32 to pass through. The fixing member 32 is located on the fixing block 31, and one end of the fixing member 32 passes through the through hole and is fixedly connected to the connecting plate. By setting the fixing block 31 and the fixing member 32, a stable connection between the female connector 10 and the connecting plate (such as the equipment housing or circuit board) is achieved, effectively eliminating the floating state, preventing the power connector from loosening and falling off due to vibration or pulling, significantly improving connection reliability, and ensuring stable power supply to the equipment.

[0040] Furthermore, in this embodiment, the fastener 32 adopts one of the following structural methods. The fastener 32 is a locking screw, which includes a nut 321a and a screw 322a. The screw 322a is located at the top of the nut 321a, and the end of the screw 322a has a threaded portion that is threaded to connect with the connecting plate. When the fastener 32 is fixed to the connecting plate, the screw 322a passes through the through hole, and the threaded portion is threaded to the connecting plate, while the bottom end of the nut 321a abuts against the limiting portion. By using the fastener 32 with a locking screw, a stable connection between the female connector 10 and the connecting plate (such as the equipment housing or circuit board) is achieved through the threaded connection between the threaded portion and the connecting plate, effectively eliminating the floating state, preventing the power connector from loosening or falling off due to vibration or pulling, significantly improving connection reliability, and ensuring stable power supply to the equipment.

[0041] Furthermore, in other embodiments, the fastener 32 employs another structural design. The fastener 32 is a snap-fit ​​connecting rod. The fastener 32 includes a snap-fit ​​cap 321b and a snap-fit ​​rod 322b. The snap-fit ​​rod 322b is located below the snap-fit ​​cap 321b, and its bottom end has a snap-fit ​​block 323b that is tightly connected to the connecting plate. The snap-fit ​​block 323b has a tapered elastic sheet 324b on its outer side, and a compression gap is provided between the elastic sheet 324b and the snap-fit ​​block. When the fastener 32 is fixed to the connecting plate, the snap-fit ​​rod 322b passes through the through hole, the snap-fit ​​block 323b is inserted into the connecting plate, and the elastic sheet 324b is compressed, so that the snap-fit ​​block 323b is tightly connected to the connecting plate, while the bottom end of the snap-fit ​​cap 321b abuts against the limiting part. By using the retaining member 32 with the snap-fit ​​connecting rod, the snap-fit ​​block 323b is tightly connected to the connecting plate through the compression between the elastic sheet 324b and the connecting plate, thus achieving a stable connection between the female connector 10 and the connecting plate (such as the equipment housing or circuit board). This effectively eliminates the floating state, prevents the power connector from loosening or falling off due to vibration or pulling, significantly improves connection reliability, and ensures stable power supply to the equipment.

[0042] Preferably, the locking assembly 40 includes a locking seat 41 and a locking block 42. The locking seat 41 has a top end of the female connector 10, and the top end of the locking seat 41 has an upward-opening snap-fit ​​interface 411. The locking block 42 is inclinedly disposed on the top end of the male connector 20, and a movable gap is formed between the locking block 42 and the male connector 20. One end of the locking block 42 has a snap-fit ​​block 421 that engages with the snap-fit ​​interface 411. By setting the locking assembly 40, and the inclined design and movable gap of the locking block 42, it is easy for the female connector 10 and the male connector 20 to be quickly inserted and automatically locked, preventing accidental disengagement and further ensuring the continuous operation of the equipment.

[0043] Preferably, the female connector 10 has female connector terminals inside, which are located within the insertion hole 11. In this embodiment, the female connector terminals are configured in three sets: ground terminal 12, neutral terminal 13, and live terminal 14, as described below. The PIN spacing between adjacent sets of female connector terminals is specifically selected according to actual product requirements, preferably a PIN spacing of 7.5mm. A first fixing part 15 is provided inside the female connector 10 and between it and the female connector terminals. The male connector 20 has a male connector terminal 22 inside, which is located within the insertion connector 21. A second fixing part 23 is provided inside the male connector 20 and between it and the male connector terminal 22.

[0044] In this embodiment, both the first fixing part 15 and the second fixing part 23 are stepped limiting blocks, which abut against the limiting parts in the middle of the female terminal and the male terminal 22 to prevent them from becoming loose. The back surfaces of the first fixing part 15 and the second fixing part 23 are inclined to facilitate the smooth installation of the female terminal and the male terminal 22 and improve the installation efficiency.

[0045] Furthermore, the female connector terminals include a ground terminal 12, a neutral terminal 13, and a live terminal 14 arranged in parallel. The insertion height of the ground terminal 12 is higher than that of the neutral terminal 13 and the live terminal 14. The female connector 10 is provided with icon sections corresponding to the ground terminal 12, neutral terminal 13, and live terminal 14. By setting the ground terminal 12, neutral terminal 13, and live terminal 14 with height differences, when the female connector 10 is plugged into the male connector 20, the ground wire is prioritized for connection, reducing the risk of leakage current and thus improving the service life of the equipment. At the same time, the icon sections allow operators to quickly and correctly plug in the connector without checking.

[0046] Preferably, both the female connector 10 and the male connector 20 are provided with outwardly protruding anti-misfit blocks 16, which are trapezoidal in shape. By providing anti-misfit blocks 16, the occurrence of operator insertion and installation errors is reduced, and the efficiency of quick and correct insertion between the female connector 10 and the male connector 20 is improved.

[0047] Preferably, the female connector 10 has a first cable holder 50 at its end for flattening and fixing the cable. The male connector 20 has a second cable holder 51 at its end for flattening and fixing the cable. By setting the first cable holder 50 and the second cable holder 51, the cable can be neatly fixed on the first cable holder 50 and the second cable holder 51, avoiding cross-interference, making the cable layout more orderly, and facilitating later maintenance and replacement.

[0048] Furthermore, the first cable holder 50 and the second cable holder 51 have the same structure, so only the first cable holder 50 will be described in detail. The first cable holder 50 includes a first upper seat 501 and a first lower seat 502. The first upper seat 501 and the first lower seat 502 are provided with staggered positioning posts 505. The first upper seat 501 and the first lower seat 502 abut against each other to form a fixing head 503 for flattening and fixing the cable. A locking block 504 is fixed at both the top and bottom ends, which is provided to engage with the female seat 10. By setting the positioning posts 505, the installation positioning efficiency between the first upper seat 501 and the first lower seat 502 is improved, and by setting the locking blocks 504, the first cable holder 50 can be quickly and easily fixed to the end of the female seat 10, thus improving the installation efficiency of the first cable holder 50.

[0049] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
