二段式電纜接頭Two-stage cable connector

本新型是有關於一種電纜接頭，特別是指一種用於將兩條電纜連接結合的二段式電纜接頭。The present invention relates to a cable joint, and more particularly to a two-stage cable joint for joining two cable joints.

已知的同軸電纜包含一個外殼、一個位於該外殼內的中心導體、一個位於該外殼內且圍繞該中心導體的絕緣體，以及一個圍繞於該絕緣體與該外殼間的外層導體。一般而言，兩個纜線線段相結合時，主要是於每一纜線線段的一端設置一個接頭部，該等接頭部分別為公接頭與母接頭，組裝時，透過螺鎖方式將該等接頭部固定，從而使該等纜線線段連結。A known coaxial cable includes a housing, a center conductor within the housing, an insulator within the housing surrounding the center conductor, and an outer conductor surrounding the insulator and the housing. Generally speaking, when two cable segments are combined, a joint portion is mainly disposed at one end of each cable segment, and the connector portions are respectively a male connector and a female connector, and when assembled, the screw connector is used to assemble the cable segments. The joint portion is fixed to connect the cable segments.

然而，由於該等接頭部間僅靠螺鎖之固定方式，當需要較頻繁地將該兩接頭部互相插拔時，每次都要轉動接頭部間的螺鎖部位，造成費時且麻煩。而且該兩接頭部螺鎖時，有時會出現兩者間未完全正對應，導致鎖歪或螺鎖過程不順利，而且螺鎖過程中該兩接頭部也較容易相對晃動。再者，除了螺鎖固定之外，也有必要思考其他的輔助結合方式，以提升該兩接頭部間的結合穩固性。目前雖然還有另一種將該等接頭部結合的方式，不採用螺鎖，而是推拔扣合(push on)方式，但仍只用單一固定結構，導致該等接頭部間的結合穩定性仍有待加強。基於上述問題，有必要針對電纜線的接頭提出改良。However, since the joint portions are only fixed by the screw lock, when the two joint portions need to be inserted and removed more frequently, the screw lock portion between the joint portions is rotated each time, which is time consuming and troublesome. Moreover, when the two joint parts are screwed, there is a case where the two parts are not completely positively corresponding, which causes the lock or screw lock process to be unsmooth, and the two joint parts are relatively easy to sway relatively during the screw lock process. Furthermore, in addition to the screw lock, it is also necessary to consider other auxiliary bonding methods to improve the bonding stability between the two joint portions. At present, although there is another way of combining the joint portions, the screw lock is not used, but the push-on method is used, but only a single fixed structure is used, resulting in the stability of the joint between the joint portions. Still needs to be strengthened. Based on the above problems, it is necessary to propose an improvement for the connector of the cable.

因此，本新型之目的，即在提供一種能克服先前技術的至少一個缺點的二段式電纜接頭。Accordingly, it is an object of the present invention to provide a two-section cable joint that overcomes at least one of the disadvantages of the prior art.

於是，本新型二段式電纜接頭，包含一個第一接頭單元，及一個第二接頭單元。該第一接頭單元包括一個第一中心導體，以及間隔設置的一個第一結合部與一個第一組裝部。該第二接頭單元可拆離地與該第一接頭單元組裝，並包括一個能與該第一中心導體接觸的第二中心導體、一個可分離地與該第一結合部嵌卡結合的第二結合部，以及一個可分離地與該第一組裝部螺鎖結合的第二組裝部。Thus, the novel two-stage cable joint comprises a first joint unit and a second joint unit. The first joint unit includes a first center conductor, and a first joint portion and a first assembly portion that are spaced apart from each other. The second joint unit is detachably assembled with the first joint unit, and includes a second center conductor that can be in contact with the first center conductor, and a second center that is detachably coupled to the first joint portion a joint portion and a second assembly portion detachably coupled to the first assembly portion.

本新型之功效在於：藉由該第一結合部與該第二結合部搭配結合，該第一組裝部與該第二組裝部搭配結合，分別作為該第一接頭單元與第二接頭單元間的第一階段固定與第二階段固定，可提升結合穩固性。而且該等結合部間為嵌卡結合，施力插拔之步驟簡單，可免除螺接方式不方便進行多次插拔的問題。再者，先將該等結合部嵌卡固定，後續要螺鎖該等組裝部時，就可避免該等組裝部於鎖固時相對晃動，從而能正向、順暢地鎖固。The effect of the present invention is that the first assembly portion and the second assembly portion are coupled together, and the first assembly portion and the second assembly portion are coupled to each other as a gap between the first joint unit and the second joint unit. The first stage is fixed and the second stage is fixed, which improves the stability of the combination. Moreover, the combination of the joints is a card-insertion, and the step of applying force and pull is simple, and the problem that the screwing method is inconvenient to perform multiple insertion and removal is eliminated. Furthermore, the bonding portions are first fixed by inserting, and when the assembly portions are subsequently screwed, the assembly portions can be prevented from relatively swaying during locking, so that the components can be locked in a positive and smooth manner.
