Abstract
Description
本發明係相關一種電連接器,特別是相關於一種電連接器的一端子接合部的接合結構,該接合結構為用以連接端子接合部及膠圈。The invention relates to an electrical connector, in particular to a joint structure of a terminal joint part of an electrical connector. The joint structure is used to connect the terminal joint part and the rubber ring.
在將一對應連接器插接於一電連接器的一端子接合部時,需要增加該對應連接器與該端子接合部之間的緊閉度及氣密度,因此在該端子接合部之外表面會套置有一膠圈。When inserting a corresponding connector into a terminal engaging portion of an electrical connector, it is necessary to increase the tightness and air density between the corresponding connector and the terminal engaging portion, so the outer surface of the terminal engaging portion There will be a rubber ring.
然而,由於該電連接器的膠圈僅單純為套設於該端子接合部之外表面,當該電連接器使用於一引擎室或類似的高溫、高壓環境中時,可能因電連接器之內部壓力與環境壓力的差異導致該膠圈位移,進而影響該對應連接器與該端子接合部之間的緊閉度及氣密度。據此,習知膠圈與端子接合部之間的接合結構有其改良之必要。However, since the apron of the electrical connector is simply sleeved on the outer surface of the terminal junction, when the electrical connector is used in an engine room or similar high-temperature, high-pressure environment, the electrical connector may The difference between the internal pressure and the ambient pressure causes the displacement of the aprons, which in turn affects the tightness and gas density between the corresponding connector and the terminal junction. Accordingly, it is necessary to improve the joint structure between the conventional rubber ring and the terminal joint.
