[0055] The edge of the plug board is provided with a flange, and the flange at the edge is surrounded by a groove. The groove is used to accommodate the epoxy glue overflowing from the first through hole to prevent the epoxy glue from overflowing to the surface of the main housing 1.

[0056] In the embodiment of the present application, the correction plate 3 is detachably connected to the main housing 1. In the manufacturing process of the through-cylinder connector, the pin terminal 2 is first inserted into the first through hole, and epoxy glue is injected into the first through hole to bond the pin terminal 2 to the first through hole; before the epoxy glue is cured, the correction plate 3 is connected to the support seat 4 of the main housing 1, so that the pin terminal 2 is inserted into the second through hole of the correction plate 3 to achieve angle correction of the pin terminal 2, so that the axis of the pin terminal 2 is collinear with the axis of the first through hole and the second through hole.

[0057] Among them, one of the main housing 1 and the correction plate 3 is provided with a slot 41, and the other of the main housing 1 and the correction plate 3 is provided with a buckle 31, and the buckle 31 is engaged with the slot 41. The main housing 1 and the correction plate 3 are engaged by the buckle 31 and the slot 41, and no fasteners are required, so the installation is convenient and simple.

[0058] Specifically, Figure 3 As shown, the support seat 4 is composed of two support plates, which are connected to the plug-in plate, and the two support plates are arranged at intervals along the length direction of the main housing 1. A card slot 41 is provided on the support plate, and the card slot 41 is set through along the thickness direction of the support plate. A buckle 31 is provided on the correction plate 3, and the buckle 31 is an L-shaped structure.

[0060] Specifically, Figure 3 As shown, two limiting holes are provided on the correction plate 3, and the two limiting holes are arranged diagonally. Two limiting posts 42 are provided at one end of the support plate away from the plug-in plate, and the two limiting posts 42 are arranged diagonally. The support plate is plugged into the limiting holes on the correction plate 3 through the limiting posts 42. The limiting posts 42 are used in conjunction with the limiting holes to not only prevent the correction plate 3 from shaking relative to the main housing 1, but also to guide the correction plate 3 to accurately engage with the support seat 4.

[0061] As an alternative embodiment, the correction plate 3 is integrally formed with the main housing 1, and a plug board is provided at the second end of the main housing 1.

The pin terminal 2 is interference-fitted with the first through hole to prevent the pin terminal 2 from shaking relative to the first through hole, and cannot be arranged colinearly with the axis of the first through hole, thereby failing to ensure that the pin terminal 2 is connected to the circuit board 8.

[0063] Specifically, Figure 4 As shown, there are multiple protrusions 21, and the multiple protrusions 21 are arranged at intervals along the length direction of the pin terminal 2.

Among them, the protrusion 21 is a tapered structure, so that the protrusion 21 is inserted into the first through hole. In addition, the protrusion 21 is a tapered structure, so that there is a gap between part of the protrusion 21 and the hole wall of the first through hole, that is, the epoxy glue can be injected into the gap, so that the protrusion 21 is connected to the hole wall of the first through hole, thereby making the connection of the pin terminal 2 more secure.

[0064] Furthermore, the pin terminal 2 is provided with a stopper 22, which abuts against the edge of the first through hole.

[0065] Specifically, Figure 4 As shown, the stop portion 22 is a part of the pin terminal 2, and the stop portion 22 is a columnar structure. The diameter of the stop portion 22 is larger than the aperture of the first through hole, so that the end of the stop portion 22 abuts against the end surface of the plug board, thereby limiting the insertion depth of the pin terminal 2.

[0066] Furthermore, a sealing ring 6 is provided on the outer peripheral surface of the main housing 1 .

[0067] Specifically, Figure 1 , Figure 2 As shown, the first end of the main housing 1 extends into the electric control box 9, and the sealing ring 6 is arranged near the first end of the main housing 1.

[0068] Furthermore, the housing assembly further comprises a mounting plate 7, which is connected to the outer peripheral surface of the main housing 1. The mounting plate 7 is used for connecting the electric control box 9 to make the connection between the cylinder connector and the electric control box 9 more secure.

[0069] Specifically, Figure 1 As shown, the mounting plate 7 is integrally formed with the main housing 1, and the mounting plate 7 is sleeved on the outer wall of the main housing 1. The mounting plate 7 is provided with two mounting holes 71, and the two mounting holes 71 are spaced apart along the length direction of the mounting plate 7. When connected with the electric control box 9, the mounting plate 7 is located inside the electric control box 9, and fits with the inner wall of the electric control box 9, and is connected by fasteners.

[0070] Preferably, a positioning column 72 is provided on the mounting plate 7 to cooperate with a positioning hole on the electric control box 9 .
