Description

Technical Field

[0001] The utility model relates to the technical field of wire and connector connection stability detection, in particular to a wire and connector connection stability detection device. Background Art

[0002] Testing the connection stability between wires and connectors is an important step to ensure the normal operation of electrical systems. Usually, wires and connectors are connected by welding. In order to detect the connection strength of the solder joints, it is necessary to perform a swing test on the solder joints between the wires and connectors. Specifically, the wires are driven to swing back and forth. If the solder joints crack or break after a small number of swings, it means that the strength of the solder joints is poor.

[0003] Currently, this type of test is carried out by driving the wire to swing through mechanical equipment, for example, driving the wire to swing back and forth through reciprocating linear motion. The problem with this type of swing is that the structure of the entire device is complex and needs to be implemented by a reciprocating linear motion mechanism. Moreover, the temperature at the solder joint position often rises rapidly during the swinging process, resulting in cracking and breaking of the solder joint. However, in actual use, although there will be swinging between the wire and the connector, the swinging frequency cannot reach the test frequency. In other words, the cracking and breaking of the solder joint caused by the temperature rise of the solder joint due to the rapid swinging during the test is not the actual desired side-view result (specifically, the swinging frequency during the test is high, which will generate a higher temperature at the solder joint position, causing the solder joint to easily crack and break at a higher temperature, but in actual use, the swinging frequency between the wire and the connector is low, and a higher temperature will not be generated at the solder joint position), which will cause the actual test result to be less accurate.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0033] A device for detecting the stability of connection between a wire and a connector is used to detect the connection strength between the wire 6 and the connector 7, and more specifically, to test the strength of the solder joint between the wire 6 and the connector 7.

[0034] like Figure 1-Figure 5 As shown, the detection device includes a movable tube 3, a base 4 and a pressing mechanism 5; wherein the movable tube 3 is vertically arranged, and the bottom of the movable tube 3 is fixedly connected to an air jet 31, and the air jet 31 is horizontally arranged. In this embodiment, two air jets 31 are arranged, and their arrangement is as follows Figure 1 and Figure 2As shown, the top end of the movable tube 3 is connected to the high-pressure gas source. Therefore, when the gas jet pipe 31 jets out gas, it drives the movable tube 3 to rotate around its own axis. At the same time, the gas jetted out by the gas jet pipe 31 can also drive the wire 6 and the connector 7 to swing relative to each other, thereby realizing the detection of the connection strength between the wire 6 and the connector 7.

[0035] like Figure 1-Figure 5 As shown, the base 4 is arranged below the movable tube 3, and the base 4 is in a circular ring shape; in this embodiment, the movable tube 3 and the base 4 are coaxially arranged.

[0036] like Figure 1-Figure 5 As shown, the pressing mechanism 5 is fixedly arranged on the base 4, and the pressing mechanism 5 includes a fixed plate 51, a movable plate 52 and an elastic member 53. The movable plate 52 is fixedly connected to the upper part of the fixed plate 51 through the elastic member 53; specifically, the fixed plate 51 can be fixedly installed on the base 4 by bolts; the elastic member 53 includes a straight spring. The fixed plate 51 is provided with a first clamp 54 for pressing the wire 6; the movable plate 52 is provided with a second clamp 55 for pressing the connector 7.

[0037] Further, such as Figure 1 and Figure 2 As shown, the top end of the movable tube 3 is rotatably connected to and communicated with the fixed tube 1 through the mechanical seal 2; the top end of the fixed tube 1 is communicated with a high-pressure gas source.

[0038] The working principle of this embodiment is as follows: the fixed tube 1 passes the high-pressure gas into the interior of the movable tube 3 through the mechanical seal 2, and then ejects the high-pressure gas through the jet tube 31, thereby driving the movable tube 3 to rotate. At the same time, when the gas ejected from the jet tube 31 also acts on the movable plate 52, the high-pressure gas will push the movable plate 52 to overcome the elastic force of the elastic member 53 and move in the direction away from the jet tube 31, so that the elastic member 53 bends and generates elastic force. When the jet tube 31 rotates until the high-pressure gas ejected from it deflects the movable plate 52, the movable plate 52 will return to its original position under the elastic force of the elastic member 53, and the inertia of the movable plate 52 itself will cause the movable plate 52 to move in the direction close to the jet tube 31, that is, the movable plate 52 will move in the direction close to the jet tube 31 under the passage of the high-pressure air ejected from the jet tube 31 as shown in the figure. Figure 4 The wire 6 and the connector 7 are swung back and forth in the direction of the two arrows shown in the figure, so that the connection strength between the wire 6 and the connector 7 can be detected. Moreover, the high-pressure gas ejected by the jet pipe 31 can drive the air at the welding position of the wire 6 and the connector 7 to flow quickly, thereby reducing the heat generated by the high-frequency swing at the welding point position, thereby improving the accuracy of the detection result.

[0039] like Figure 1-Figure 5As shown, the first clamp 54 and the second clamp 55 both include a U-shaped plate 541, a connecting plate 542 and a bolt 543; the U-shaped plate 541 is fixedly connected to the connecting plate 542 to form a frame-like structure, which is arranged horizontally; the bolt 543 is threadedly penetrated through the connecting plate 542; the air outlet of the air injection pipe 31 faces the U-shaped plate 541 of the second clamp 55. By rotating the bolt 543, the position of the U-shaped plate 541 can be adjusted. For example, in this embodiment, by rotating the bolt 543 clockwise, the wire 6 and the connector 7 can be pressed together, while by rotating the bolt 543 counterclockwise, the pressing effect on the wire 6 and the connector 7 can be released.

[0040] like Figure 3-Figure 5 As shown, the first clamp 54 further includes a first sliding groove 544 opened on the fixed plate 51 , and the U-shaped plate 541 on the first clamp 54 is horizontally slidably connected to the fixed plate 51 through the first sliding groove 544 .

[0041] like Figure 3-Figure 5 As shown, the second fixture 55 further includes a second sliding groove 551 provided on the movable plate 52 , and the U-shaped plate 541 on the second fixture 55 is horizontally slidably connected to the movable plate 52 via the second sliding groove 551 .

[0042] like Figure 3-Figure 5 As shown, the second clamp 55 also includes a baffle 552, which is fixed on the U-shaped plate 541 of the second clamp 55. The baffle 552 can increase the surface area so that the force of the high-pressure gas ejected from the injection pipe 31 can be transmitted to the movable plate 52 as much as possible, thereby increasing the swing amplitude of the movable plate 52.

[0043] like Figure 3-Figure 5 As shown, the second clamp 55 further includes two soft pads 553, which are respectively fixed on two oppositely disposed side surfaces of the movable plate 52 and the U-shaped plate 541. The soft pads 553 can be used to protect the connector 7 and prevent the connector 7 from being damaged by excessive extrusion.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
