Description

Technical Field

[0001] This utility model relates to the field of terminal plugging technology, and in particular to a quick plugging device. Background Technology

[0002] In the field of MLCC (Multilayer Ceramic Capacitor) aging testing, high-temperature / high-voltage accelerated testing is a core component in evaluating product reliability. This test is typically conducted using a multilayer ceramic capacitor aging test chamber. However, traditional aging test chambers generally employ single-point direct-insertion terminal interfaces. During operation, each terminal pin must be inserted one by one into the chamber's socket, ensuring that each terminal is correctly inserted into its corresponding socket. For example, when connecting 12 stations, the operator must perform at least 36 actions (aligning, inserting, and pressing the 12 terminals), which is inefficient and prone to causing muscle fatigue. Because the terminals are uniform in shape and closely spaced (typically 5-8mm), manual insertion is prone to errors. Incorrect terminal insertion can lead to invalid test data or even MLCC overload damage. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a quick plug-in device that can insert multiple plug terminals into a socket at the same time to prevent mis-plugging of plug terminals.

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figure 1-3 As shown, a quick-connect device according to a preferred embodiment of the present invention includes:

[0023] The lower plate 1 has multiple first through holes 11 that correspond one-to-one with the multiple sockets on the socket. That is, by adjusting the position of the lower plate 1, the sockets can be aligned with the first through holes 11 one-to-one (coaxial setting).

[0024] Upper plate 2 is disposed opposite to lower plate 1 and is detachably connected. Upper plate 2 is provided with second through holes 21 that correspond one-to-one with the first through hole 11.

[0025] The plug-in terminal 3 is provided in multiple ways. The plug-in terminal 3 includes a cylindrical body 31 and a pin 32. The cylindrical body 31 is inserted into the first through hole 11 in a corresponding manner. The top of the cylindrical body 31 is provided with a positioning flange 311, which is located between the upper plate 2 and the lower plate 1 and is clamped by the bottom surface of the upper plate 2 and the top surface of the lower plate 1. That is, the outer diameter of the positioning flange 311 is larger than the diameter of the first through hole 11 and the diameter of the second through hole 21, respectively. The bottom end of the cylindrical body 31 extends out of the bottom end of the first through hole 11. The top end of the inner hole of the cylindrical body 31 is connected to the second through hole 21. The top end of the pin 32 is inserted and fixed in the bottom end of the inner hole of the cylindrical body 31, and the bottom end of the pin 32 extends out of the cylindrical body 31. It can be understood that the first through hole 11, the second through hole 21, the cylindrical body 31 and the pin 32 are coaxially arranged to ensure that multiple pins 32 can be inserted into the sockets of multiple sockets in a corresponding manner.

[0026] The working principle of this implementation is as follows: During assembly, first connect the top end of the pin 32 to the wire, then insert and fix the top end of the pin 32 to the bottom end of the cylinder 31, while the wire extends from the top end of the inner hole of the cylinder 31. Then, pass the bottom end of the cylinder 31 through the corresponding first through hole 11 (determined according to the socket into which the plug terminal 3 needs to be inserted). Next, fix the upper plate 2 and the lower plate 1 together, so that the upper plate 2 and the lower plate 1 cooperate to clamp the positioning flange 311, while the wire extends from the top end of the second through hole 21. At this time, multiple plug terminals 3, the upper plate 2 and the lower plate 1 are connected into a whole, completing the assembly of this device. During use, first adjust the position of this device so that the positions of the multiple pins 32 are aligned with the positions of the multiple sockets on the socket. The pins 32 are aligned one-to-one, and then the upper plate 2 is pressed to insert them into their corresponding sockets, thus enabling the multiple connectors 3 to be connected to their corresponding sockets quickly and accurately. Compared to the traditional method of connecting each connector individually, this eliminates the tedious steps of individual connection. Operators only need to insert the assembled device into the socket of the aging chamber, saving a lot of time and effort and greatly improving work efficiency. Since the connectors 3 are first inserted and fixed into their corresponding first through holes 11, when the entire device is directly inserted into the socket, it can be ensured that each connector 3 is connected to its corresponding socket, avoiding the misconnection phenomenon that is easy to occur when the connectors 3 are inserted one by one, thus improving the accuracy and reliability of the test.

[0027] For example, the bottom of the upper plate 2 is provided with a positioning groove 22 that corresponds to and cooperates with the positioning flange 311. By cooperating with the positioning flange 311 and the positioning groove 22, it is easy to realize the positioning connection between the cylinder 31 and the upper plate 2.

[0028] For example, the cylinder 31 is provided with a first variable diameter section 312, the diameter of which gradually decreases from top to bottom. The top of the first variable diameter section 312 is connected to the bottom of the positioning flange 311. During assembly, the bottom of the first variable diameter section 312 gradually embeds into the first through hole 11, thereby facilitating the adjustment of the relative position of the positioning flange 311 and the first through hole 11, and ensuring that the cylinder 31 and the first through hole 11 are coaxially arranged.

[0029] For example, the cylinder 31 is also provided with a second variable diameter section 313, the top of the second variable diameter section 313 is connected to the bottom of the first variable diameter section 312, and the diameter of the second variable diameter section 313 gradually increases from top to bottom, so that the cylinder 31 can pass through the first through hole 11.

[0030] For example, the top of the pin 32 is provided with a connecting part 321, which is threaded to the bottom end of the inner hole of the cylinder 31 to realize the fixed connection between the pin 32 and the cylinder 31. It can be understood that the connecting part 321 is made of conductive material. By connecting the wire to the connecting part 321, the conductive connection between the pin 32 and the wire can be realized. In order to facilitate the connection between the connecting part 321 and the wire, a boss with a diameter smaller than the diameter of the first through hole 11 can be provided on the top of the connecting part 321.

[0031] For example, the middle part of the pin 32 is provided with a clamping part 322. The cross-section of the clamping part 322 is a regular hexagon. During assembly, rotating the clamping part 322 can drive the connecting part 321 and the pin 32 to rotate, thereby facilitating the threaded connection between the connecting part 321 and the bottom end of the inner hole of the cylinder 31.

[0032] For example, the lower plate 1 is provided with a first fixing hole 12, and a fixing bolt 13 passes through the first fixing hole 12. The upper plate 2 is provided with a second fixing hole 23 aligned with the first fixing hole 12. The fixing bolt 13 is threadedly connected to the second fixing hole 23. During assembly, first ensure that the first fixing hole 12 and the second fixing hole 23 are aligned, and then the fixing bolt 13 passes through the first fixing hole 12 and is threadedly connected to the second fixing hole 23, so that the upper plate 2 and the lower plate 1 are clamped together with the positioning flange 311, thereby realizing the detachable connection between the upper plate 2 and the lower plate 1. The assembly and disassembly are simple. In this embodiment, the bottom of the lower plate 1 is provided with a countersunk hole for accommodating the bolt head of the fixing bolt 13 to prevent the bolt head of the fixing bolt 13 from protruding.

[0033] For example, the upper plate 2 and the lower plate 1 are made of polytetrafluoroethylene, which has good heat resistance and wear resistance, ensuring electrical safety under high voltage environment and smooth insertion and removal.

[0034] 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 substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
