Background technology
Apply to the electric connector in the higher field of the vibration environment such as locomotive, space flight, must can meet GB/T 21563-2008 " rail transit rolling stock equipment shock and vibration test " the harshest grade vibration test requirement, and BTM antenna terminal is exactly the one in above-mentioned electric connector.Traditional BTM antenna terminal as shown in Figure 1, it comprises housing 101, the rear end of housing 101 is equipped with packing ring 102, rubber cushion 103 and tail cover 104 from front to back successively, its middle washer 102, rubber cushion 103, all by overlapping 105 compacted with the tail of housing 101 threaded engagement, can be wrapped after packing ring 102 is compacted on corresponding cable to realize sealing.
Known by describing above, the packing ring of existing BTM antenna terminal, rubber cushion and tail cover is only fix by screw thread, and in use, cable through tail cover to overlap with tail and directly contacts, under the environment vibrated or when cable swings, the situation that unavoidable meeting causes tail to overlap and loosens occurs, especially when cable swings, its power produced constantly is broken and is pulled tail cover, what very easily cause tail to overlap loosens, once there is the situation that tail cover loosens, then BTM antenna terminal afterbody entirety can be caused to retreat, and then cause outer conductor to connect insecure problem.Meanwhile, rubber cushion easily produces corrosion, and the rubber cushion be clipped between tail cover and packing ring is corroded, then its length will change, and the locking finally causing tail to overlap was lost efficacy, and the problem that this also can cause tail cover to get loose occurs.
Summary of the invention
The object of the present invention is to provide a kind of Anti-loose BTM antenna terminal, overlap with the tail solving existing Anti-loose BTM antenna terminal the problem easily got loose.
Meanwhile, the present invention also aims to provide the Anti-loose BTM mounting structure of antenna terminal.
In order to solve the problem, Anti-loose BTM antenna terminal of the present invention is by the following technical solutions: Anti-loose BTM antenna terminal, comprise housing, the rear end of housing is equipped with tail cover and the seal member for coordinating with the corresponding cable seal entering housing, tail cover and housing threaded engagement, be provided with anti-inversion organization between described tail cover and housing, seal member comprises the vibration damping sealing ring be located in tail cover.
Described anti-inversion organization comprises the elasticity internal tooth packing ring pushing up and be contained between tail cover front end and housing.
Be provided with pad between described internal tooth packing ring and housing, spin-endedly between pad with housing coordinate.
Described anti-inversion organization comprise be located at housing and tail overlap between jackscrew.
Also comprise guard shield assembly, guard shield assembly comprises the front sheath of the installation panel for clamping BTM antenna terminal and rear sheath, forward and backward sheath threaded engagement, described housing is provided with outer turning edge, housing outer turn edge be clamped at rear sheath between front end and front sheath.
The mounting structure of Anti-loose BTM antenna terminal is by the following technical solutions: the mounting structure of Anti-loose BTM antenna terminal, comprise Anti-loose BTM antenna terminal and installation panel, described Anti-loose BTM antenna terminal comprises housing, the rear end of housing is equipped with tail cover and the seal member for coordinating with the corresponding cable seal entering housing, tail cover and housing threaded engagement, be provided with anti-inversion organization between described tail cover and housing, seal member comprises the vibration damping sealing ring be located in tail cover.
Described anti-inversion organization comprises the elasticity internal tooth packing ring pushing up and be contained between tail cover front end and housing.
Be provided with pad between described internal tooth packing ring and housing, spin-endedly between pad with housing coordinate.
Described anti-inversion organization comprise be located at housing and tail overlap between jackscrew.
The outside of housing is also equipped with guard shield assembly, guard shield assembly comprises the front sheath of the installation panel for clamping BTM antenna terminal and rear sheath, forward and backward sheath threaded engagement, described housing is provided with outer turning edge, housing outer turn edge be clamped at rear sheath between front end and front sheath.
Because described seal member has been set to the vibration damping sealing ring be located in tail cover by Anti-loose BTM antenna terminal of the present invention, therefore the hidden danger that gets loose that rubber cushion of the prior art brings can be eliminated, also make it possible to arrange anti-inversion organization between tail cover and housing, thus the tail solving existing Anti-loose BTM antenna terminal overlaps the problem easily got loose simultaneously.
Further, elasticity internal tooth packing ring can make tail overlap and produce the trend of revolving tighter and tighter between housing, not only can realize loosening, and housing and tail can be made to overlap combine tightr; Guard shield assembly achieves the comprehensive shielding of BTM antenna terminal.
