Description
本發明係與硬體管道使用的管道內視鏡有關，特別是指一種管道內視鏡之頭段與纜線之組合。The invention relates to a pipe endoscope used in a hard pipe, and particularly refers to a combination of a head section of a pipe endoscope and a cable.
現今使用於管道的管道用內視鏡，例如台灣第M441952號專利，即為本案申請人於之前所申請的管道內視鏡，主要使用於下水管道或流道的檢查。此類的管道內視鏡，其本身並不具有一般微型工業內視鏡可操控內視鏡頭端向某側擺動的擺頭結構，因此本身沒有操控擺頭的功能，在進入管道後僅能靠使用者的操作或前後推動來在管道中過彎，並藉由其內視鏡頭段的可撓頸部的彈簧提供回彈力量來使其可撓頸部在彎曲後得以回復直線狀態。Nowadays, pipeline endoscopes used in pipelines, such as Taiwan Patent No. M441952, are the pipeline endoscopes previously applied by the applicant for this case, which are mainly used for inspection of sewer pipes or runners. This type of pipe endoscope does not have a swing head structure that can control the end of the inner view lens to swing to a certain side of the general miniature industrial endoscope. Therefore, it does not have the function of controlling the swing head. It can only rely on it after entering the pipe. The user operates or pushes forward and backward to make a bend in the pipe, and the spring of the flexible neck of the inner view lens section provides a resilient force to restore the flexible neck to a straight state after bending.
現今的管道內視鏡，在深入管道時常會因需要過彎而彎曲，但又需要有堅挺的強度來維持其可推進的狀態，這樣才能順利的將內視鏡的頭端推入來進行檢視，實務上常會在主電纜線中心設置一個可撓的硬質骨幹(例如條狀玻璃纖維)，藉以提供較高強度的彈力以及結構強度，再將連接用的電源線或訊號線等電線佈設於該硬質骨幹的周圍，最後再以外皮包覆該等電線。而此種主電纜線在組裝於內視鏡頭段時，目前的做法是將該主電纜線的一端與一線端連接件相連接，再將該線端連接件連接於該內視鏡頭段，並將該主電纜線周圍的電線連接於該線端連接件內的一電路板或其他電子元件，而該電路板或電子元件則是以黏膠或焊接或其他固定方式固定在該線端連接件內，藉此達到穩定的電性連接的結果。Today’s pipe endoscopes are often bent due to the need to bend when they go deep into the pipe, but they also need to have a strong strength to maintain their propellable state, so that the end of the endoscope can be smoothly pushed in for inspection. , In practice, a flexible rigid backbone (such as a strip of glass fiber) is often set in the center of the main cable to provide higher strength elasticity and structural strength, and then connect the power cord or signal line and other wires to the Around the hard backbone, the wires are finally covered with a sheath. When this kind of main cable is assembled in the inner view lens segment, the current method is to connect one end of the main cable to a wire end connector, and then connect the wire end connector to the inner view lens segment, and Connect the wires around the main cable to a circuit board or other electronic component in the terminal connector, and the circuit board or electronic component is fixed to the terminal connector by glue or welding or other fixing methods In this way, a stable electrical connection is achieved.
然而，目前的做法，在實際使用時，因為該主電纜線常常會推進或拉出於管道，因此就會產生各種不同方向的彎折及復原的反覆彎曲又伸直的動作，在收線時也會需要彎曲纏繞於捲線盤上，而這種反覆彎曲又伸直的動作會造成內部的硬質骨幹相對於外皮在軸向上的位移，隨著使用次數的累積，這個位移量就會愈來愈大。而由於主電纜線是以外皮固定在可撓頸部的線端連接件，因此外皮就不相對於該線端連接件移動，前述的位移量就會造成該硬質骨幹相對於該線端連接件移動，最後就造成該硬質骨幹在該線端連接件內向內推擠到其他元件，甚至於推動電路板使其脫離被膠固定的狀態而造成電線的連接關係被破壞的故障，或是推擠與電子元件連接的焊點或電線，而造成焊錫裂開或電線斷裂等問題。However, the current practice, in actual use, because the main cable is often pushed or pulled out of the pipe, it will produce various directions of bending and recovery of repeated bending and straightening. It will also need to be bent and wound on the reel, and this repeated bending and straightening action will cause the internal rigid backbone to be displaced in the axial direction relative to the outer skin. As the number of uses accumulates, this displacement will increase. Big. Since the main cable is a wire end connector with a sheath fixed to the flexible neck, the outer sheath does not move relative to the wire end connector, and the aforementioned displacement will cause the rigid backbone to be relative to the wire end connector. Move, and finally cause the hard backbone to push inward to other components in the wire end connector, or even push the circuit board out of the state of being fixed by glue, causing the failure of the connection relationship of the wires to be damaged, or pushing The solder joints or wires connected to the electronic components cause problems such as cracking of the solder or wire breakage.
本發明之主要目的在於提出一種管道內視鏡之頭段與纜線之組合，其藉由一擋件來提供擋止效果，可確保具有硬質骨幹的纜線在使用的過程中，不會因為反覆的彎曲及復直的關係而導致硬質骨幹相對於外皮位移而推入線端連接件，進而避免了線端連接件內部的元件被推擠而脫離原來位置。The main purpose of the present invention is to provide a combination of the head section of the pipe endoscope and the cable, which uses a stopper to provide a blocking effect, which can ensure that the cable with a rigid backbone will not be damaged during use. The relationship between repeated bending and straightening causes the rigid backbone to shift relative to the outer skin and push into the wire end connector, thereby preventing the internal components of the wire end connector from being pushed out of the original position.

為了詳細說明本發明之技術特點所在，茲舉以下之較佳實施例並配合圖式說明如後，其中：In order to describe the technical features of the present invention in detail, the following preferred embodiments are described in conjunction with the drawings, in which:
如圖1至圖7所示，本發明一較佳實施例所提出之一種管道內視鏡之頭段與纜線之組合10，主要由一內視鏡頭段11、一線端連接件31、一擋件41以及一纜線51所組成，其中：As shown in Figures 1 to 7, a combination of the head section and cable of a pipe endoscope proposed in a preferred embodiment of the present invention is mainly composed of an inner
該內視鏡頭段11，具有一頭部12以及一可撓頸部21，該頭部12內部具有一取像模組、一光源模組。該取像模組與該光源模組係為習知構件且非本案之申請重點，容不以圖式表示，其細節亦無需於此詳述之。The inner

該線端連接件31，連接於該可撓頸部21的另一端，該線端連接件31呈筒狀而形成一內部空間32，該線端連接件31中央穿設一穿孔34連通於該內部空間32，且該線端連接件31具有一中空的環形柱體36，該環形柱體36的中部分在空間上連通於該穿孔34以及該內部空間32。The wire
該擋件41，具有一環狀身部42以及一擋肋44，該擋肋44通過該環狀身部42的軸線並以兩端分別連接於該環狀身部42，且該擋肋44與該環狀身部42之間形成複數鏤空部46，該擋件41係固設於該線端連接件31，且該環形柱體36被該環狀身部42圍繞，該擋肋44位於該環形柱體36之一端。於本實施例中，該擋件41與該線端連接件31之間的固設關係，乃是藉由該環狀身部42緊配於該環形柱體36來形成的。而前述的緊配方式，可以是該環狀身部42緊包覆該環形柱體36，也可以是該環狀身部42內面設置複數凸肋421，而以該複數凸肋421抵於該環形柱體36表面來形成，而於本實施例中則以具有該複數凸肋421為例。除了緊配的方式之外，若還要再更求穩固，則還可以再施加黏膠(由於黏膠係存在於縫隙中難以於圖中表示，因此不以圖式表示之)於該環形柱體36與該擋件41，藉以將該二者黏固，來提供額外的固定效果，於本實施例中係以有設置該黏膠為例，但不設置該黏膠亦可以藉由前述緊配關係來達成固設的效果。The
該纜線51，具有一骨幹52、複數電線54以及一外皮56，該複數電線54係圍繞而設置於該骨幹52周圍，該外皮56則包覆該複數電線54及該骨幹52，該纜線51係以一端由外穿入該穿孔34而伸入至該線端連接件31的該內部空間32，且該纜線51藉由該外皮56固定於該線端連接件31而使其伸入於該內部空間32的部分位於該環形柱體36所圍合的範圍內，且該複數電線54係穿過該複數鏤空部46而用來與其他元件連接。The
該擋肋44的作用是用來擋止該骨幹52的端面。在實際實施時，本實施例中係以在組裝時就將該骨幹52的端面抵於該擋肋44為例，藉以直接發生擋抵的效果；而其他種實施狀態中，也可以在組裝時使該骨幹52的端面相距該擋肋44一預定距離，並不以抵住為必要。The function of the
前述的結構中，並不具有該擋件41與該環形柱體36之間的定位機制，而若為了在組裝上的精度考量，則可以在該擋件41與該環形柱體36之間設計一個定位機制，其具體做法如下：於該擋肋44兩端分別延伸一足部441來連接於該環狀身部42的端緣，藉以使該擋肋44位於該環狀身部42的一端，並且使該擋肋44通過該環狀身部42軸線的位置遠離該環狀身部42的端緣而與該端緣相隔預定距離；並且，於該擋肋44的身部朝向該環形柱體36延伸複數擋止塊442，而擋止於該環形柱體36的端緣。藉由該複數擋止塊442擋止於該環形柱體36的端緣，可以確保該擋件41與該環形柱體36組裝時的相對位置於一定，形成了一定的定位效果。In the aforementioned structure, there is no positioning mechanism between the
以上說明了本實施例的結構，接下來說明本實施例的操作狀態。The structure of this embodiment has been explained above, and the operation state of this embodiment will be explained next.
如圖6及圖7所示，在組裝完成的情況下，該擋件41係固設於該環形柱體36，該纜線51係組設於該線端連接件31，而該骨幹52則抵住該擋肋44。在該纜線51經過長時間使用之後，即反覆的進行了多次的彎曲又伸直的動作之後，該纜線51內部的該骨幹52即使原來可能會相對於該外皮56產生位移，然而卻被該擋肋44所阻擋而不會再向該內部空間32進一步的伸入，因此不會推擠到其他元件，也不會如習知技術般的推擠到該線端連接件31內部的電路板(圖中未示)而造成其脫離被膠固定的狀態，因此避免了內部電線54的連接關係被破壞的故障問題。As shown in Figures 6 and 7, when the assembly is completed, the
由於該複數擋止塊442僅是用來產生組裝上的定位效果，對於防止上述纜線51中的該骨幹52進一步伸入該內部空間32的問題並無貢獻，因此其設置與否並非必要，而為組裝上是否有定位要求的選項之一。Since the plurality of
如圖8所示，該內視鏡頭段11’也可以不具有該可撓頸部，而可以僅具有該頭部12’，並以該線端連接件31’直接連接於該頭部12’即可。亦即，該內視鏡頭段11’並不以具有該可撓頸部為限。只是在不具有該可撓頸部的狀況下，在管道內前進時遇到彎道即較不容易過彎，而適用於較無彎折的管道，不過，由於在收線時仍會因捲繞於捲線盤(圖中未示)而使得該纜線51’產生彎曲的狀況，因此該纜線51’仍會有反覆彎曲及伸直的狀況，而可能推擠到該線端連接件31’內部的電路板(圖中未示)或電子元件(圖中未示)，因此仍需要以本案之技術來解決前述問題。As shown in FIG. 8, the inner view lens section 11' may not have the flexible neck, but may only have the head 12', and the wire end connector 31' is directly connected to the head 12' That's it. That is, the inner view lens section 11' is not limited to having the flexible neck. Only in the absence of the flexible neck, it is less likely to bend when encountering a curve when advancing in the pipe, and it is suitable for pipes with relatively no bends. However, it will still be curled when the wire is taken up. Winding around the reel (not shown in the figure) causes the cable 51' to bend, so the cable 51' will still be repeatedly bent and straightened, and may be pushed to the wire end connector 31 'Internal circuit boards (not shown in the figure) or electronic components (not shown in the figure), so the technology of this case still needs to solve the aforementioned problems.
