Description

Technical Field

[0001] The present invention belongs to the technical field related to electric connectors and cable assemblies, and particularly relates to a potting tool. Background Art

[0002] Currently, the two most common potting methods for electrical connectors are dispensing machines and manual potting. These two methods have the following characteristics: First, dispensing machines offer precise control over the amount of glue dispensed, making them suitable for high-volume production and highly efficient. However, their disadvantages are high cost and low adaptability. Different products require different potting molds, and for small batches, machine commissioning takes a long time. Frequent product changes can also significantly reduce efficiency. Second, manual potting offers advantages such as high adaptability, simple tooling, and low cost. However, its disadvantages include the inability to precisely control the amount of glue dispensed, which can lead to product quality issues. Furthermore, manual potting is inefficient, and high production volumes can lead to operator fatigue, increasing the likelihood of quality issues. The aforementioned cable termination methods all have significant limitations, impacting the production efficiency of electrical connectors and cable assemblies in terms of processing cost and flexibility.

[0033] Furthermore, the shape of the fixing plate 14 is an irregular plate structure. The fixing plate 14 is provided with a first circular through hole 1401 and a second circular through hole 1402 for mounting the syringe 4. The second circular through hole 1402 has a narrow groove 1403 in the circumferential direction. A through hole and a threaded hole are provided in the thickness direction of the fixing plate 14. The through hole and the threaded hole are respectively provided on both sides of the narrow groove 1403. The second circular through hole 1402 is sleeved on the outside of the connecting rod 2.

[0034] The main body of the dial 9 is a disc structure with a boss. A threaded through hole 903 is provided at the center of the disc. A third circular through hole 901 and a small narrow slot 902 are provided on the boss. A through hole and a threaded hole are provided in the thickness direction of the dial 9. The through hole and the threaded hole are respectively arranged on both sides of the small narrow slot 902. The tail of the positioning screw 8 is provided with an anti-slip groove nut, and a square through hole 801 is opened on the anti-slip groove nut; the positioning screw 8 is threadedly connected to the threaded through hole 903, and a square boss 1102 is provided at one end of the connecting body 11, and a second circular through hole 1101 is provided on the other side of the connecting body 11. The square boss 1102 is installed in the square through hole 801, and the pointer 10 is movably plugged into the second circular through hole 1101. The two through holes and the threaded hole are threadedly connected to the locking screw 13.

[0035] Furthermore, the syringe 4 is a hollow cylindrical structure, one end of which is a conical structure and the other end of which is a hollow thin cylindrical structure.

[0036] Furthermore, the needle 3 has an outer shape of a hollow cylindrical structure, and the lower end is a slender hollow cylindrical structure.

[0040] Example: When using this device, place the connector to be encapsulated with glue at the top of the base 1. First, add glue to the syringe 4. Then, rotate the positioning screw 8. When the positioning screw 8 drives the push rod 6 downward, the elastic force of the spring 7 prevents the push rod 6 from descending too quickly due to inertia, resulting in excessive glue discharge. The push rod 6 drives the rubber sleeve 5 to squeeze the glue inside the syringe 4. The glue flows out of the needle 3 and encapsulates the connector to be encapsulated with glue. When the positioning screw 8 rotates, it also drives the connector 11 to rotate. The pointer 10 mounted on the connector 11 rotates simultaneously. The lower end of the pointer 10 moves on the dial 9, making it easy to check the distance moved and thus the volume of glue. The volume of glue applied each time can be precisely controlled, and operation is convenient. When the positioning screw 8 is rotated, the spring 7 rebounds in time when the positioning screw 8 rises, driving the push rod 6 upward.
