Description

Technical Field

[0001] This utility model relates to the field of circuit connection, and in particular to a through-board connector. Background Technology

[0002] Through-board connectors achieve circuit continuity by having terminals inside the socket at the core contact and engage with pins inside the connector. Existing through-board connectors have a simple structure, consisting only of the core, terminals, housing, nut, and sealing ring. Shielding is difficult at the cable connection point, failing to achieve complete shielding for the entire cable. Utility Model Content

[0003] This utility model proposes a through-plate connector, which is used to pass through a plate and connect to a plug to achieve circuit conduction.

[0004] The through-plate connector proposed in this utility model includes:

[0005] The outer shell has multiple limiting grooves on its inner wall;

[0006] A rubber core is disposed inside the outer shell. The outer wall of the rubber core is provided with a positioning protrusion that cooperates with the limiting groove. A terminal is disposed inside the rubber core, and the wiring end of the terminal extends out of the rubber core.

[0007] A cable, wherein the connecting end of the cable is connected to the wiring terminal of the terminal;

[0008] A shielding shell is connected to the outer shell and covers the wiring terminals of the terminals and the connection terminals of the cables.

[0009] Furthermore, in the through-plate connector as described above, the core includes a core front end and a core rear end that are interconnected, the positioning protrusion is disposed on the outer side of the sidewall of the core rear end; the terminal extends from the core rear end.

[0010] Furthermore, in the through-plate connector described above, a potting groove is provided on the outer side wall of the rear end of the core.

[0011] Furthermore, in the through-plate connector described above, the front end of the rubber core is fitted with a rubber core sealing ring.

[0012] Furthermore, in the through-plate connector described above, the housing includes a housing tail end, a housing body, a housing sealing ring, and a housing fixing member. The housing tail end is connected to the housing body and is close to the shielding shell. The housing fixing member and the housing sealing ring are both sleeved on the outer side wall of the housing body, and the housing sealing ring is located between the housing fixing member and the housing tail end.

[0013] Furthermore, in the through-plate connector described above, the outer side wall of the housing body is provided with an external housing thread, which is used to connect the housing fastener.

[0014] Furthermore, in the through-plate connector described above, the inner wall of the main body of the housing is provided with an internal thread, which is located near the tail end of the housing; the shielding shell includes a front end and a rear end of the shielding shell that are connected to each other, the front end of the shielding shell is provided with an external thread, and the internal thread of the housing mates with the external thread of the shielding shell to connect the shielding shell and the housing.

[0015] Furthermore, in the through-plate connector described above, the rear end of the shielding shell is crimped to the cable.

[0016] Furthermore, in the through-plate connector described above, the sidewall of the shielding shell is provided with a potting hole. After the shielding shell is connected to the cable, glue is injected into the interior of the shielding shell through the potting hole to fix the cable and the shielding shell.

[0017] Furthermore, the through-plate connector described above includes an outer mold that covers the shielding shell and the cable.

[0018] The advantage of this invention lies in the addition of a shielding shell and an outer mold, which not only provides better sealing capabilities but also achieves the purpose of shielding the entire cable.

[0019] On the other hand, by cooperating with the positioning protrusion of the core and the limiting groove of the outer shell, relative rotation between the core and the outer shell can be avoided during assembly. The design of multiple limiting grooves allows for multiple embodiments of the through-plate connector of this invention, each with a different arrangement of the sockets 23. Therefore, when the connector is "L"-shaped, meaning the insertion direction of the connector is perpendicular to the cable exit direction, a through-plate connector with matching sockets can be assembled according to the cable exit direction, thereby improving the applicability of this invention.

[0034] like Figure 1 and Figure 2 As shown, the through-plate connector of this utility model is used to connect to a plug after passing through a plate to achieve circuit conduction. The through-plate connector includes: a shell 1, a rubber core 2, a cable 3, a shielding shell 4, and an outer mold 5. The rubber core 2 is disposed inside the shell 1, the cable 3 is connected to the rubber core 2, the shielding shell 4 is connected to the shell 1 and covers part of the rubber core 2 and part of the cable 3, and the outer mold 5 covers the shielding shell 4.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the housing 1 includes a housing body 11, a housing tail end 12, a housing sealing ring 13, and a housing fixing member 14. The housing body 11 is connected to the housing tail end 12. The housing sealing ring 13 and the housing fixing member 14 are both sleeved on the outside of the housing body 11, with the housing sealing ring 13 located between the housing fixing member 14 and the housing tail end 12. The housing fixing member 14 is used to fix the through-plate connector after it has passed through the plate.

[0036] Combination Figure 5 As shown, the inner sidewall of the outer shell body 11 is provided with an inner shell thread 111 and a plurality of limiting grooves 112. The inner shell thread 111 is located near the tail end 12 of the outer shell, and the limiting grooves 112 are located near the end of the inner shell thread 111 away from the tail end 12 of the outer shell.

[0037] Preferably, the outer side wall of the outer shell body 11 is provided with an external thread 113 near the tail end 12 of the outer shell, and the inner side wall of the outer shell fixing member 14 is provided with a fixing internal thread 141. Thus, when the through-plate connector is inserted into the plate, the external thread 113 and the fixing internal thread 141 cooperate to fix the through-plate connector to the plate. The outer shell sealing ring 13 is located between the outer shell fixing member 14 and the plate, and plays a buffering role.

[0038] Preferably, the end of the outer shell body 11 away from the tail end 12 is provided with a plug thread 114 for connection and fixation with a plug connector. The plug thread 114 can be an internal thread or an external thread, depending on the connection structure of the plug connector.

[0039] Preferably, the outer side wall of the housing body is provided with an anti-rotation plane 115 to prevent the through-plate connector from rotating after being inserted into the plate.

[0040] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the core 2 includes a front end 21, a rear end 22, a socket 23, and a terminal 24. The front end 21 and the rear end 22 are connected, the socket 23 passes through the front end 21 and the rear end 22, and forms a socket opening 231 at the front end of the core. The terminal 24 is inserted into the socket 23.

[0041] The outer sidewall of the rear end 22 of the adhesive core is provided with a positioning protrusion 221, which can be inserted into any one of the limiting grooves 112 of the outer shell 1. Since the outer shell 1 and the adhesive core 2 are connected by adhesive, the cooperation between the limiting groove 112 and the positioning protrusion 221 can prevent relative rotation between the outer shell 1 and the adhesive core 2 during the process of pouring glue and waiting for the glue to solidify. By inserting different limiting grooves 112, the mating angle between the outer shell 1 and the adhesive core 2 can be changed, thereby changing the arrangement of the insertion holes 23. In a preferred embodiment of this utility model, the number of limiting grooves 112 is eight.

[0042] Preferably, the side wall of the rear end 22 of the glue core is provided with a plurality of glue filling grooves 222, which are used to fill glue into the gap between the glue core 2 and the outer shell 1 through the glue filling grooves 222 after the positioning protrusion 221 of the glue core 2 is inserted into the limiting groove 112 of the outer shell 1.

[0043] The terminal 24 includes a plug-in end (not shown in the figure) and a wiring end 241 that are connected to each other. The plug-in end is inserted into the socket 23, and the wiring end 241 extends from the rear end 22 of the core and is connected to the cable 3.

[0044] like Figure 2 and Figure 8 As shown, the cable 3 includes a connecting end 31, which is connected to the wiring terminal 241 of the terminal 24.

[0045] The shielding shell 4 includes a front end 41 and a rear end 42 that are interconnected. An external thread 411 is provided on the side wall of the front end 41, which mates with the internal thread 111 of the outer shell, connecting the outer shell 1 and the shielding shell 4, so that the front end 41 covers the terminal 241 of the terminal 24. The connection end 31 of the cable 3 is inserted into the shielding shell 4, and the rear end 42 of the shielding shell is directly pressed into the shielding layer of the outer wall of the cable 3, thereby the shielding shell 4 covers the terminal 241 and the connection end 31 of the cable 3.

[0046] Preferably, a potting hole 43 is provided on the outer wall of the connection between the front end 41 and the rear end 42 of the shielding shell. After the cable 3 is connected to the terminal 24, the shielding shell 4 is connected to the outer shell 1, and the shielding shell 4 is connected to the cable 3, sealant is injected into the shielding shell 4 through the potting hole 43 to fill the gaps between the cable 3, the shielding shell 4, and the terminal 24, and to complete the fixation. This achieves and improves the stable shielding effect of the entire cable.

[0047] The advantage of this utility model is that it adds structures such as shielding shell 4 and outer mold 5, which not only meet the requirements of better sealing capability, but also achieve the purpose of shielding the entire cable.

[0048] On the other hand, by cooperating with the positioning protrusion 221 of the core 2 and the limiting groove 112 of the outer shell 1, relative rotation between the core 2 and the outer shell 1 can be avoided during assembly. The design of multiple limiting grooves 112 allows the through-plate connector of this utility model to have multiple embodiments, each with a different arrangement of the sockets 23. Thus, when the plug is "L"-shaped, that is, the plug insertion direction is perpendicular to the cable exit direction, a through-plate connector with matching sockets 23 can be assembled according to the cable exit direction, thereby improving the applicability of this utility model.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the present utility model's technical solution shall still fall within the scope of the present utility model's technical solution.
