Each positioning member 314 may be, for example, a block structure which is injection molded to clad and engage with the signal conductor 311. When the signal conductor modules 31 pass through the sealing member 32, the two positioning members 314 of each signal conductor module 31 are fixed in the positioning groove 321 of the sealing member 32, so that the signal conductor module 31 is tightly positioned in the sealing member 32. As for a state that the two positioning members 314 are fixed in the positioning groove 321 of the sealing member 32, that airtightness can be attained is taken as main focus. And a manner that the positioning member 314 is engaged with the signal conductor 311 is considered to be capable of avoiding the signal conductor 311 generating friction relative to the sealing member 32 or other provided environment to cause damage to the signal conductor 311 when the signal conductor 311 is pulled to displace. [0038] The number of the positioning member 314 of the present embodiment is provided as two, but implementing, as long as an object that the corresponding signal conductor module 31 is tightly positioned in the sealing member 32 can be attained, the number of the positioning member 314 also may be provided as only one. Moreover, although the two positioning members 314 of the present embodiment are provided to be spaced apart from each other by a certain distance, in implementing, it also may be that the two positioning members 314 are tightly attached together, and an epoxy resin is filled in the positioning groove 321 of the sealing member 32 at a side of the two positioning members 314 to strengthen sealing.

[0039] Referring to FIG. 3 and FIG. 8 to FIG. 11, the protective sleeve 4 sheathes an outer periphery of the rear frame 14, and is operatable to change between a retraction state (as shown in FIG. 8, FIG. 9) and an extending out state (as shown in FIG. 10, FIG. 11) that the protective sleeve 4 protrudes rearwardly relative to the rear frame 14. In the present embodiment, the protective sleeve 4 substantially is in form of hollow barrel and includes a top wall 43, a bottom wall 44, two side walls 45 which connect the top wall 43 and the bottom wall 44, and two sliding grooves 41 which are respectively provided to the top wall 43 and the bottom wall 44 and extend along a direction that the protective sleeve 4 is slidable in the front-rear direction, and a rear edge of each side wall 45 is forwardly recessed relative to the top wall 43 and the bottom wall 44 to form a cable outgoing notch 42. Each cable outgoing notch 42 is used to allow a signal cable connected to the second inserting assembly 92 to go out sideward therefrom.

[0040] Each sliding groove 41 is formed with an inserting hole 411 at a middle position of the sliding groove 41 between two ends of the sliding groove 41, a diameter of the sliding groove 41 is larger than an outer diameter of the threaded segment 121 of the position-limiting member 12 and is smaller than an outer diameter of the operating portion 123, a width of the sliding groove 41 is preferably provided to be larger than an outer diameter of the rod segment 122 and is smaller than the outer diameter of the threaded segment 121. When the protective sleeve 4 sheathes the rear frame 14, the two position-limiting members 12 respectively pass through the two sliding grooves 41 from the two inserting holes 411 of the two sliding grooves 41 respectively and the two threaded segments 121 are respectively locked to the top plate 141b and the bottom plate 141c of the rear frame 14, and the two rod segments 122 can slide respectively in the two sliding grooves 41, so that sliding of the protective sleeve 4 relative to the rear frame 14 is limited to be along an extending direction of the sliding groove 41. And that positions of the two position-limiting members 12 on the top wall 43 and the bottom wall 44 are staggered with each other up and down may provide stabler guiding and sliding of the protective sleeve 4 when the protective sleeve 4 slides relative to the rear frame 14. And when the position-limiting member 12 is removed from the protective sleeve 4, it needs to move the position-limiting member 12 to be aligned with a position of the inserting hole 411, firstly locking of the threaded segment 121 is released from the rear frame 14 by a rotating operation, and then the threaded segment 121 of the position-limiting member 12 is pulled out from the inserting hole 411. So, it may prevent an operator from excessively rotating the position-limiting member 12 to release locking of the position-limiting member 12 and from causing the position-limiting member 12 to be improperly detached from the sliding groove 41 when the operator needs to change the retraction state or the extending out state of the protective sleeve 4.

[0041] Referring to FIG. 8 and FIG. 9, when it needs to make the second adapter 22 exposed out from the rear plate 142 of the rear frame 14, by that the protective sleeve 4 slides forwardly, the protective sleeve 4 is in a retraction state that the protective sleeve 4 entirely and essentially overlaps with and sheathes the outer periphery of the rear frame 14, that is, it may make the second adapter 22 exposed out to allow the second inserting assembly 92 to insert therein or pull out therefrom, and at this time, the two position-limiting members 12 are respectively at rear ends of the two sliding grooves 41, further, by rotating the operating portions 123 of the two position-limiting members 12, the two position-limiting members 12 are respectively locked so that the operating portions 123 of the two position-limiting members 12 respectively press against the top wall 43 and the bottom wall 44 of the protective sleeve 4, the protective sleeve 4 also may be limited so that the protective sleeve 4 does not easily slide rearwardly. When it needs to avoid the second inserting assembly 92 which has inserted into the second adapter 22 being subjected to impact from an external force, or based on requirement on protecting the second adapter 22, as shown in FIG. 10 and FIG. 11, by that the protective sleeve 4 slides rearwardly, the protective sleeve 4 in an extending out state that the protective sleeve 4 rearwardly extends out from the rear frame 14 relative to the rear frame 14, that is, the second adapter 22 may be shrouded in the protective sleeve 4, and the second inserting assembly 92 also is at least partially positioned in a protecting space 40 of the protective sleeve 4 to be shrouded by the protective sleeve 4, thereby avoiding the second inserting assembly 92 which has inserted into the second adapter 22 is subjected to impact from an external force, or protecting the second adapter 22, and at this time, the two position-limiting members 12 are at front ends of the two sliding grooves 41 respectively, further, by rotating the operating portions 123 of the two position-limiting members 12, the two position-limiting members 12 are respectively locked so that the operating portions 123 of the two position-limiting members 12 press against the top wall 43 and the bottom wall 44 of the protective sleeve 4 respectively, the protective sleeve 4 also may be limited so that the protective sleeve 4 does not easily slide forwardly.

[0042] As for the retraction state and the extending out state of the protective sleeve 4, the retraction state takes, that the second inserting assembly 92 is inserted into or pulled out from the second adapter 22 is not hindered by the protective sleeve 4, as main focus, and the extending out state takes, that the protective sleeve 4 can obstruct an external force to avoid the external force impacting the second inserting assembly 92 to affect signal connection of the second inserting assembly 92 and even make the second inserting assembly 92 detached from the second adapter 22 or avoid the external force impacting the second adapter 22 and avoid the second adapter 22 being damaged, as main focus.

[0043] When the feedthrough device of the present disclosure is used to transmit signals between the first equipment and the second equipment, firstly the front frame 13 of the housing unit 11 is mounted on a wall of the first equipment (for example, a vacuum chamber), and the first inserting assembly 91 is inserted into one of the first adapters 21 of the plurality of adapter units 2, and then the second inserting assembly 92 is inserted into one of the second adapters 22 of the plurality of adapter units 2. Next, as long as the protective sleeve 4 is operated to rearwardly extend out from the rear frame 14 relative to the rear frame 14, the protective sleeve 4 and the rear frame 14 cooperate with each other to define the protecting space 40, so that the second inserting assembly 92 can be protected, in turn it avoids the second inserting assembly 92 being subjected to an unexpected external force to be damaged even be detached from the second adapter 22.

[0044] In conclusion, in the present disclosure, with a design that the protective sleeve 4 is provided so that the protective sleeve 4 is operatable to change between the retraction state and the extending out state, when the protective sleeve 4 is in the extending out state, the protective sleeve 4 rearwardly extends out from housing structure 1 and shrouds the second adapter 22, the protective sleeve 4 can protect the second inserting assembly 92 inserted into the second adapter 22, in turn the protective sleeve 4 can avoid the second inserting assembly 92 being subjected to impact from an unexpected external force, and when the protective sleeve 4 is in the retraction state, the protective sleeve 4 also does not affect that the second inserting assembly 92 is inserted into or pulled out from the second adapter 22, therefore, the object of the present disclosure may be indeed attained.

[0045] In addition, by that the sealing member 32 of each signal conductor unit 3 is provided with the plurality of positioning grooves 321, in cooperation with a design that each signal conductor module 31 has the positioning members 314, the positioning members 314 of each signal conductor module 31 can be fixed and positioned in the corresponding positioning groove 321, so that the signal conductor module 31 does not easily slide and displace to cause the signal conductor module 31 to be damaged when the signal conductor module 31 is subjected to an external force, which is beneficial to maintain quality of signals to be transmitted.
