Description

Technical Field

[0001] This utility model relates to the field of electronic information network technology, specifically to an electronic network transformer housing with a guiding function. Background Technology

[0002] A network transformer is a type of transformer used in data communication and computer networks. It converts electrical signals into digital signals, enabling data transmission within a computer network. Network transformers typically employ magnetic coupling technology, offering features such as input / output isolation, interference prevention, and improved signal-to-noise ratio. They are widely used in local area networks (LANs), wide area networks (WANs), and data centers.

[0003] A known authorized patent application with application number CN202220232743.1 discloses a foolproof housing and a network transformer. Its background art addresses the problem that "sometimes markings are placed on the cover to distinguish the orientation of network transformers, etc. This is because different orientations of the network transformer result in different relationships between the pins and leads; if the network transformer is in the wrong orientation, it will be unusable. When placing the cover on the housing, workers need to carefully distinguish the orientation of the housing, which is time-consuming and laborious." The proposed solution addresses this problem by including a foolproof housing and a coil. The foolproof housing includes a housing and a cover with orientation markings. Multiple pins are provided on the side wall of the housing. The cover is placed on the housing. Two locking parts are provided at each end of the housing, with unequal spacing between the locking parts at both ends. A locking tongue matching the locking parts is provided on one side of the cover.

[0004] However, in implementing the relevant technology, the following problems were found in the above technical solution: it is inconvenient to limit the movement of the magnetic core coil during use. The above solution installs the magnetic core coil inside the outer casing, but during the winding process, it is easy to pull the magnetic core coil, causing the coil to shift and the coil winding to become loose, thereby reducing the assembly quality and performance of the transformer. Utility Model Content

[0005] This invention proposes an electronic network transformer housing with a guiding function, which solves the problem of inconvenience in limiting and preventing movement of the magnetic core coil in related technologies.

[0006] The technical solution of this utility model is as follows: an electronic network transformer housing with a guiding function, comprising: a housing with an open top, wherein the housing has a stepped receiving groove inside;

[0007] Multiple pins are located on both sides of the top of the casing;

[0008] A limiting plate is disposed inside the outer shell, and the limiting plate slides along the length direction of the outer shell via a guide mechanism disposed on the outer shell;

[0009] Two sets of fixing holes are symmetrically opened on the stepped end face inside the outer shell;

[0010] Connecting lugs are symmetrically fixedly installed on both sides of the limiting plate;

[0011] And a locking mechanism provided on the connecting ear block and inserted into the fixing hole, wherein the position of the limiting plate can be fixed by the locking mechanism after it is moved.

[0012] Preferably, the locking mechanism includes a movable rod that is slidably connected to the connecting lug, a pin that is fixedly connected to the bottom end of the movable rod and inserted into the fixing hole, a spring that is sleeved on the surface of the movable rod, and a pull plate that is fixedly connected to the top end of the movable rod.

[0013] The two ends of the spring are connected to the connecting lug and the pin respectively, and a handle is fixedly installed on the top of the pull plate.

[0014] Preferably, the guiding mechanism includes guide grooves formed on both sides of the inner wall of the receiving groove of the outer shell, and guide blocks fixedly installed on both sides of the limiting plate and slidably connected with the guide grooves.

[0015] Preferably, the PIN pin includes a winding end and a soldering end. The winding end has a structure design that is narrow in the middle and wide at both ends, and the narrow recessed part in the middle is the winding part. One end of the soldering end has a structure design that extends outward and bends.

[0018] The working principle and beneficial effects of this utility model are as follows:

[0019] By placing the coil in the receiving slot, pulling the handle moves the pull plate upward, causing the movable rod to move the pin upward and separate from the fixing hole, compressing the spring. Then, the moving limit plate guides the coil to contact the inner wall of the housing. Releasing the handle causes the movable rod to move downward and reset via the spring, allowing the pin to insert into the fixing hole and fix the limit plate. The coil is then fixed by the cooperation between the limit plate and the inner wall of the housing. This achieves the effect of limiting the coil and preventing movement, ensuring the uniformity of winding and effectively improving the assembly quality and performance of the network transformer.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1

[0030] Please see Figure 1 - Figure 6 The present invention provides an electronic network transformer housing with a guiding function, comprising: a housing 1 with an open top, and a stepped receiving groove inside the housing 1;

[0031] Multiple pins are located on both sides of the top of the outer casing 1;

[0032] A limiting plate 2 is provided inside the outer shell 1, and the limiting plate 2 slides along the length direction of the outer shell 1 through a guide mechanism provided on the outer shell 1;

[0033] Two sets of fixing holes 3 are symmetrically opened on the stepped end face inside the outer shell 1;

[0034] Connecting lugs 4 are symmetrically and fixedly installed on both sides of the limiting plate 2;

[0035] And a locking mechanism is provided on the connecting ear block 4 and is inserted into the fixing hole 3. After the limiting plate 2 moves, its position can be fixed by the locking mechanism.

[0036] The locking mechanism includes a movable rod 5 that is slidably connected to the connecting lug 4, a pin 6 that is fixedly connected to the bottom end of the movable rod 5 and inserted into the fixing hole 3, a spring 7 that is sleeved on the surface of the movable rod 5, and a pull plate 8 that is fixedly connected to the top end of the movable rod 5.

[0037] The two ends of the spring 7 are connected to the connecting lug 4 and the pin rod 6 respectively, and a handle is fixedly installed on the top of the pull plate 8.

[0038] The guiding mechanism includes guide grooves 9 formed on both sides of the inner wall of the receiving groove of the outer shell 1, and guide blocks 10 fixedly installed on both sides of the limiting plate 2 and slidably connected to the guide grooves 9.

[0039] The technical solution provided in this embodiment is as follows: In use, the coil is placed inside the receiving groove of the outer casing 1. Then, the handle is pulled upward to move the pulling plate 8 upward. At the same time, the pulling plate 8 moves the movable rod 5 upward, thereby causing the movable rod 5 to move the pin rod 6 upward and separate from the fixing hole 3. The pin rod 6 compresses the spring 7. Then, the pulling plate 8 is moved to move the limiting plate 2 into contact with the coil. At the same time, the limiting plate 2 moves the guide block 10 to slide in the guide groove 9 to ensure the stability of the movement of the limiting plate 2. The limiting plate 2 pushes the coil to move along the receiving groove towards the inner wall at one end to guide the movement of the coil until the coil contacts the inner wall. Then, the handle is released, and the spring 7 moves the coil upward. The movable rod 5 moves down to reset, thereby inserting the pin rod 6 into the corresponding fixing hole 3 to fix the position of the limiting plate 2. At this time, the coil can be fixed by the cooperation between the limiting plate 2 and the inner wall of the receiving groove, which facilitates winding. Thus, the coil is limited and prevented from moving during winding, avoiding the coil from moving due to pulling and affecting the winding effect. This helps to ensure the uniformity of winding and effectively improves the assembly quality and use effect of the network transformer. After the coil is wound, the limiting plate 2 is separated from the coil and a new coil is placed in it. At the same time, the limiting plate 2 is moved to make the new coil contact the wound coil, and the limiting plate 2 is fixed before winding can be done again. This cycle is repeated to complete the assembly of the transformer.

[0040] Furthermore, the PIN pin includes a winding end 11 and a soldering end 12. The winding end 11 has a structure design that is narrow in the middle and wide at both ends, and the narrow recessed part in the middle is the winding part. One end of the soldering end 12 has a structure design that extends outward and bends. Multiple guide grooves 13 that are adapted to the PIN pin are opened on both sides of the inner wall of the outer shell 1.

[0041] Specifically, the coil leads are led out from the guide groove 13 and wound around the winding end 11, and finally the soldering end 12 is connected to the circuit board.

[0042] Example 2

[0043] Based on Embodiment 1, in this embodiment: a cover 14 is provided on the top of the outer shell 1, and a snap-fit ​​mechanism for connection is provided between the cover 14 and the outer shell 1.

[0044] The snap-fit ​​mechanism includes positioning blocks 15 fixedly installed at both ends of the bottom of the cover 14, guide blocks 16 integrally formed on one side of the positioning blocks 15, positioning grooves 17 opened at both ends of the outer shell 1 and adapted to the positioning blocks 15, and snap-fit ​​grooves 18 opened on the inner wall of the positioning grooves 17 and snap-fit ​​with the guide blocks 16. The positioning blocks 15 are made of a material with a certain degree of elasticity, such as plastic, which can undergo a certain degree of elastic deformation. The guide blocks 16 have a slope to facilitate the opening of the positioning blocks 15.

[0045] The technical solution provided in this embodiment is as follows: By setting the cover 14, the coil and PIN pin inside the outer shell 1 can be protected. When installing the cover 14, by aligning the positioning block 15 and the positioning groove 17 and moving the cover 14 down, as the cover 14 moves down, the guide block 16 contacts the positioning groove 17. Under the guidance of the inclined surface of the guide block 16, the positioning block 15 can be driven to expand outward and undergo elastic deformation. After the cover 14 is placed on the outer shell 1, the guide block 16 and the snap-fit ​​groove 18 are aligned. At the same time, the positioning block 15 resets and drives the guide block 16 and the snap-fit ​​groove 18 to snap together, thereby achieving the function of fixing the cover 14.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
