For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] See also Figure 1-5 The embodiment of the present application provides a through-cylinder connector, one end of which passes through the mounting hole 201 of the cylinder body 200 and is sealed and connected to the first female end, and the other end of which is sealed and connected to the second female end.

[0035] The through-cylinder connector includes: a connector body 10 and a terminal 20, wherein the terminal 20 is inserted into the connector body 10. The connector body 10 is provided with a fixing portion 11, a first plug-in portion 12 and a second plug-in portion 13, wherein the first plug-in portion 12 and the second plug-in portion 13 are respectively arranged at both ends of the fixing portion 11, and the two ends of the terminal 20 are respectively located in the first plug-in portion 12 and the second plug-in portion 13.

The second buckle structure 124 and the elastic arm buckle 123 are respectively provided on different side walls of the first slot 121 to ensure the rigidity of the first slot 121. Preferably, the second buckle structure 124 can be a second notch, or other buckle structure that can be buckled with the first female end.

[0041] See also Figure 4 Furthermore, a third buckle structure 133 is provided on the side wall of the second slot 131 for buckling with the second female end. Preferably, the third buckle structure 133 can be a third notch or other buckle structure that can buckle with the second female end, for stably fixing the second female end to the connector body 10. Furthermore, a plurality of protruding ridges 132 are provided on the outer surface of the second plug-in portion 13 for foolproof positioning when the second female end is inserted.

[0042] See also Figure 4 Furthermore, a sealing groove 1211 is provided at the bottom of the first slot 121, a sealing medium is provided in the sealing groove 1211, and the terminal 20 is inserted in the sealing medium, and the sealing medium is used to fill the connection gap between the terminal 20 and the connector body 10, and is used to increase the sealing performance of the connector body 10. It is understandable that the sealing medium can be an encapsulated epoxy resin, or other methods that can achieve the same sealing effect.

[0043] Furthermore, a sealing rubber pad may be provided inside the first slot 121, and when the first female end is inserted, it abuts against the bottom or inner wall of the first slot 121. The sealing rubber pad is clamped between the first female end and the first slot 121 to achieve sealing abutment between the two.

[0044] See also Figure 2-4 Furthermore, the connector body 10 is further provided with a sealing portion 14, which is provided between the fixing portion 11 and the first plug-in portion 12, and is in sealing contact with the mounting hole 201, and is used to block the mounting hole 201. The sealing portion 14 is provided with at least one annular groove 141 and at least one sealing member 142, and the sealing member 142 is correspondingly provided in the annular groove 141, and protrudes from the notch of the annular groove 141, and is in sealing contact with the inner wall of the mounting hole 201.

[0046] See also Figure 6 and Figure 7 Furthermore, in some embodiments, chamfered sections are provided at both ends of the terminal 20 to facilitate plugging with the first female end and the second female end. A locking section 21 is provided in the middle of the terminal 20, and the locking section 21 is embedded in the connector body 10, between the bottom of the sealing groove 1211 and the bottom of the second slot 131.

[0047] Specifically, at least one side wall of the locking section 21 is provided with a locking block 211 protruding from the side wall, which is used to prevent the terminal 20 from falling off. The locking block 211 is two angularly symmetrically arranged protrusions, wherein one end of one protrusion is connected to the edge of the side wall where it is located, and the other end is arranged close to the other protrusion, and the parts where the two protrusions are close to each other protrude from the side wall where they are located. The locking block 211 can be stamped and formed, which is convenient for production.

[0048] Furthermore, in some embodiments, each side wall of the terminal 20 is provided with a locking block 211 to increase the friction between the terminal 20 and the connector body 10 to prevent the terminal 20 from falling out of the connector body 10 .

[0049] See also Figure 2 and Figure 3 Further, in some embodiments, the fixing portion 11 is fixedly connected to the cylinder body 200 at the periphery of the mounting hole 201, and the fixing portion 11 may be provided with a positioning portion for achieving a fixed connection with the cylinder body 200. The positioning portion may be a positioning hole or other methods, which will not be described in detail herein.

[0050] Furthermore, a plurality of hollow grooves are cut on the end surface of the fixing portion 11 facing the second plug-in portion 13 to prevent the connector body 10 from shrinking during the injection molding process due to excessive thickness of part of the rubber material, and also to save costs.
