Abstract
The utility model relates to an electrical connector card retreating mechanism, which is provided with an active part, the active part comprises a shell, a base and a push rod, the shell has three sides and an opening arranged toward the electrical connector, the base is assembled from the opening of the shell and fixedly connected with the shell, the push rod is detained in a detaining space enclosed by the base and the shell and can move pre and post through the vertical direction, the base where is corresponding to the opening of the shell is provided with a pair of card tenons, the card tenons are separately buttoned on the edges of the two lateral walls of the shell which are mutual parallel, which can limit the change of the distance of the two lateral walls.
Description
[technical field]
The utility model is about a kind of electric connector trip mechanism, refers to that especially a kind of segmented that realizes moves back the electric connector trip mechanism of card motion.
[background technology]
Along with the utilization of all kinds of card-type electronic assemblies such as memory card, electronic cards on different electronic installations is increasingly extensive, can accommodates the card-type electronic assembly that is loaded with the data with different content at any time and realize that the electronic card coupler that telecommunication is transmitted between card-type electronic assembly and electronic installation also becomes more and more important.Common electronic cards or memory card be because number of contacts is many, so it need utilize trip mechanism set on the electric connector usually with after electronic card coupler docks, and just is convenient to electronic cards is withdrawed from outside the electric connector.
Relevant trip mechanism of the present utility model such as No. the 99227777.9th, People's Republic of China's patent announcement, see also Fig. 1, this trip mechanism 6 has the state of pushing and recoil state, and it comprises housing 61, pedestal 62 and catch bar 63, and housing 61 lengthwises to three sidewall double teams live pedestal 62.When trip mechanism 6 is in recoil state, catch bar 63 relative housings 61 are given prominence to than length, because of being subjected to external force, housing 61 easily cause its lengthwise to open the two side up and down, thus when being subjected to improper external force, housing 61 and pedestal 62 easily break away from left and right directions, the catch bar 63 that is in 61 of housings thus has bigger amount of movement, can produce bigger deflection even fracture when catch bar 63 is subjected to improper external force.
[summary of the invention]
The purpose of this utility model is to provide a kind of bond strength that can increase the pedestal and the housing of trip mechanism, and can prevent the electric connector trip mechanism of throw-out lever fracture.
The purpose of this utility model is achieved in that this trip mechanism is provided with initiative part, this initiative part comprises housing, pedestal and push rod, wherein this housing has three sides and an opening towards the setting of electric connector direction, pedestal from the opening group of housing go into and with the housing Joint, in the receiving space that push rod then is accommodated in pedestal and housing and is enclosed and can move forward and backward along longitudinally, wherein be provided with a pair of trip near the aperture position of this pedestal corresponding housing, this trip is held in respectively on the edge, two side that housing is parallel to each other.
Compared with the prior art, the utlity model has following advantage: during because of the trip mechanism assembling, the trip of pedestal is held on the edge, two side up and down of housing, the spacing that can limit this two sidewall thus changes, and avoiding being in has bigger amount of movement even fracture when push rod between housing is subjected to improper external force.

Fig. 3 is the stereogram of the utility model electric connector trip mechanism when being in recoil state.
Fig. 4 is the cutaway view of Fig. 3 along the IV-IV direction.
[embodiment]
See also Fig. 2 to Fig. 4, this trip mechanism 1 has the state of pushing and recoil state, and it is installed on the side of electric connector (not label) in order to the metallic matrix 2 of an electromagnetism bridging effect, comprises initiative part 3 and follower (not label), wherein follower is a prior art, does not repeat them here.Initiative part 3 comprises push rod 30, pedestal 31, sliding part 32 and the housing 33 that is equiped with elastic component 34, and wherein push rod 30 close pedestal 31 1 sides are concaved with the accepting groove 301 of the tool breach 3010 of certain depth, and these accepting groove 301 bottom lands are equiped with shell fragment 3011.
Housing 33 has three sidewalls and an opening towards the setting of electric connector (not label) direction, its along lengthwise to being arranged with upper side wall 332 and lower wall 333 in parallel, wherein lower wall 333 lengthwises are arranged with two cantilever type elastic arms 331 to two ends, and these elastic arm 331 ends are to extend to upper side wall 332 directions to be provided with.Pedestal 31 has the body 310 that lengthwise extends, this body 310 is provided with heart-shaped guide channel 311, and be provided with stop section 312 perpendicular to the extension of body 310 1 sides, near the aperture position of these stop section 312 vertical both sides corresponding housing 33 respectively projection be provided with trip 313, trip 313 be provided with vertical portion 3131 and in the vertical portion the extended hook part 3132 of 3131 terminal horizontal, pedestal 31 lengthwises to elastic arm 331 positions of a side corresponding housing 33 respectively projection be provided with projection 314.Sliding part 32 is installed in the accepting groove 301, this sliding part 32 be provided with can slippage in the guide channel 311 of pedestal 31 guide posts 320.
After trip mechanism 1 assembling, push rod 30 is contained in pedestal 31 and the housing 33 formed receiving spaces (not label) and can moves forward and backward along longitudinally, and the guide posts 320 that makes sliding part 32 of the motion by push rod 30 produces the segmented slippages along the guide channel 311 of pedestal 31, and trip mechanism 1 is changed pushing between state and recoil state.The hook part 3132 of 31 two trips 313 of pedestal fastens with the upper side wall 332 of housing 33 and lower wall 333 respectively, and then the upper side wall 332 of housing 33 can outwards not open relatively with lower wall 333.Again, the elastic arm 331 of housing 33 is resisted against on corresponding pedestal 31 projections 314, and projection 314 exceeds elastic arm 331 terminal certain-lengths, and it can prevent that housing 33 is separated on left and right directions because of making pedestal 31 and housing 33 after opened by improper external force.After trip mechanism 1 is in recoil state, push rod 30 goes out than length with respect to housing 33 emergences, yet pedestal 31 combines closely with housing 33, and makes push rod 30 little at the amount of movement of 333 of housing 33 upper side walls 332 and lower wall, so easy fracture not when push rod 30 is subjected to external force.
