Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, connector of the present utility model, comprises terminal fixed block 10, conducting terminal (not shown) and blind plugging terminal 22(can be installed referring to Fig. 5 to Fig. 7 on terminal fixed block 10).Terminal fixed block 10 is removably installed in the cavity volume of connector shell 30.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, terminal fixed block 10 has front surface 11 and rear surface 12.Terminal fixed block 10 is provided with the installing hole 13 for mounting terminal.Installing hole 13 can be through hole, and the front surface 11 of through hole self-retaining piece 10 extends to rear surface 12.One end that through hole is positioned at fixed block front surface 11 is provided with to the scotch 112 of installing hole 13 extensions, scotch 112 seals part installing hole 13, be used for stopping blind plugging terminal, prevent that blind plugging terminal 22 from dropping out from front surface 11 one end of the terminal fixed block of installing hole 13.
As shown in Figure 2, Figure 3 and Figure 4, on terminal fixed block 10, be also provided with buckle 14, after inserting installing hole 13 at terminal, terminal remained on to installing hole 13, prevent that terminal from therefrom exiting.Buckle 14 comprises buckle body 141 and stopper 142.Buckle body 141 one end are connected in installs on hole wall 131, and the other end can relatively be installed hole wall 131 and move up and down (shown in Fig. 9), forms and is arranged in installing hole and protrudes from the elastic component that hole wall 131 is installed.Buckle body 141 can have gap with installation hole wall 131, forms and is arranged in installing hole and protrudes from the flexure strip that hole wall 131 is installed.In example as shown in Figure 3, buckle body 141 axially has an acute angle angle α with installing hole 13.
As shown in Fig. 5, Fig. 6 and Fig. 7, terminal comprises conducting terminal 21 and blind plugging terminal 22.Blind plugging terminal 22 comprises terminal body 221 and dop 224.Terminal body 221 has a upper surface 222; Terminal body 221 upper surfaces 222 have a depressed part 223.After being in place in the installing hole 13 of terminal at terminal fixed block 10, the stopper 142 that the depressed part 223 in terminal body 221 coordinates on buckle 14, prevents that terminal from exiting from installing hole 13.
During use, terminal dop 224 is alignd with stopper 142 1 sides, then terminal dop 224 is inserted in installing hole 13 from 12 one end, rear surface of terminal fixed block 10.During insertion, terminal dop 224, by 14 jack-up of the buckle on terminal fixed block 10, makes it to depart from lock-out state, thereby dop 224 is entered in installing hole 13.When dop 224 approaches or touches the scotch 112 of fixed block 10 front ends, terminal is in place.Now, the stopper 142 on buckle 14 is positioned at the depressed part 223 on blind plugging terminal 22, thereby makes buckle 14 recover its lock-out state, prevents that terminal from exiting from installing hole 13.
As Fig. 8, Fig. 9, Figure 10 shows that blind plugging terminal 22 is installed on the first state in installing hole 13, i.e. lock-out state.When the first state, the scotch 112 of fixed block 10 front ends stops that blind plugging terminal 22 crosses forward the front surface 11 of fixed block 10.Stopper 142 on fixed block 10 is positioned at depressed part 223 places of terminal body 221, and is positioned in the direction of motion that dop 224 exits from installing hole 13.Therefore, blind plugging terminal 22 can not move to front surface 11 directions of terminal fixed block, also cannot move to rear surface 12 directions of terminal fixed block.Stopper 142 stops that dop 224 exits installing hole 13.
Blind plugging terminal 224 during the first state is the second state after installing hole 13 inward turning turnbacks.Figure 11 and Figure 12 are that blind plugging terminal 22 is installed on the second state in installing hole 13, i.e. lock status not.When blind plugging terminal 224 is positioned at the second state, terminal dop 224 is positioned at axial passage 135 1 sides, and stopper 142 is no longer positioned on the exit axis of dop 224.Because dop 224 is offset to terminal body 221 ends, and dop 224 width W 5 are less than the width W 3 of axial passage 135 in terminal fixed block 10, and dop 142 can exit in the axial passage 135 of installing hole 13.Therefore also just realized the taking-up of blind plugging terminal 22.
The blind plugging terminal 224 that is positioned at the second state can be got back to again the first state (being lock-out state) after installing hole 13 inward turning turnbacks.
Terminal fixed block 10 in the utility model and blind plugging terminal 22 also can have other and change structural design.For example, terminal dop 224 protrudes from the upper surface 222 of terminal body.Terminal body 221 has leading flank 225 and trailing flank (not shown).Trailing flank is relative with leading flank 225.Dop 224 protrudes from the height that terminal body 221 leading flanks and dop 224 protrude from terminal body upper surface 222 and is greater than the height that dop 224 protrudes from corresponding terminal body leading flank 225; Or dop 224 protrudes from the height that corresponding terminal body 221 trailing flanks and dop 224 protrude from terminal body upper surface 222 and is greater than the height that dop 224 protrudes from terminal body trailing flank; Or dop 224 does not protrude from one of terminal body 221 leading flanks or trailing flank or both.
According to the variation structural design of above-mentioned blind plugging terminal 22, buckle 14 both can arrange stopper 142, also stopper 142 can be set.When stopper 142 is not set, buckle body 141 can be used for stopping dop 224.Blind plugging terminal 22 be installed on installing hole 13 interior after, when the upper surface 222 of buckle 14 and terminal body is relative, buckle body 141 or stopper 142 are positioned in the direction that dop 224 exits and stop that dop 224 exits.Dop 224 is in installing hole after 90-degree rotation or 270 degree, and buckle body 141 or stopper 142 are no longer positioned in the direction that dop 224 exits, and dop 224 can exit.
Embodiment in the utility model, only for the utility model is described, does not form the restriction to claim scope, and other substituting of being equal in fact that those skilled in that art can expect, all in the utility model protection range.
