Two strains stop part 38 to be placed on the position corresponding with the upper deformable space 27 of Socket casing 21 and lower deformable space 27 respectively.Strain stops the Width end of part 38 to be connected on the inner surface of each side plate 37 and stops part 38 to strengthen strain.Shown in Fig. 7 and 9, when keeper 23 was in interim latched position in Socket casing 21, strain stoped part 38 from deformability space 27 forward.Therefore, armed lever 26 can strain makes jack terminals joint 22 can insert cavity 24 or removes from cavity 24.On the other hand, strain stops part 38 to advance in the deformability space 27, and stops the distortion of armed lever 26 when keeper 23 is in main latched position shown in Figure 10.When keeper 23 was in anterior latched position, the antetheca 25 of Socket casing 21 and the antetheca 40 of keeper 23 matched each other in the vertical.In addition, when keeper 23 is in main latched position, even when producing the full-size tolerance between the resin of the resin of Socket casing 21 and keeper 23, the rear end of the front end of the auxiliary spigot surface 31 in bottom and the lug spigot surface 42 of keeper 23 also overlaps towards each other in the footpath.Thereby guarantee auxiliary spigot surface 31 performance guide functions.When keeper 23 was in main latched position, the front surface of the front surface of keeper 23 and Socket casing 21 roughly flushed each other.The front surface of the front surface of keeper 23 and Socket casing 21 is coupled on the front surface of terminal fitting retaining part 13.When guide plate 39 inserts in the guiding cavity 32 of Socket casings 21, the vertically moving of guide plate 39 guiding keepers 23.

Shown in Fig. 3,4 and 7, roughly be provided with lock arm 45 in the width center of Socket casing 21 upper surfaces, be used for when Socket casing 21 is engaged in plug casing 11, plug casing 11 and Socket casing 21 being kept together.Lock arm 45 has two cantilever beams 46.Treat that latching segment 47 connects the centre position of two beams 46, and operation part 48 connects the rear end of two beams 46.Two beams 46 separate with predetermined space and are almost parallel to each other.Each beam 46 has the front ends at the anterior place of Socket casing 21, and can be about this front end strain on the vertical direction that intersects with longitudinal direction, and its middle shell is combined together in a longitudinal direction and removes.The rear portion locking face for the treatment of latching segment 47 almost is vertically upright.But the front surface for the treatment of latching segment 47 is inclined upwardly to its rear end from its front end.Can make lock arm 45 strains from top extrusion operation part 48.At two opposite side places of lock arm 45, protective bulkhead 49 reaches the position that is higher than lock arm 45 on the upper surface of Socket casing 21.Two guiding ribs 50 are at two cross side longitudinal extensions of Socket casing 21 lower surfaces.Finger tabs 51 is extended between two guiding ribs 50 in the rear end of Socket casing 21 lower surfaces.

As shown in figs. 1 and 10, be provided with lock claw portion 16 on the upper wall 15 of the cover 14 of plug casing 11, lock claw portion 16 can be locked on the lock arm 45.Lock pawl 16 inwardly stretches out in the general width center of upper wall 15 front ends of cover 14.The front surface of lock pawl 16 is inclined upwardly from its rear end to its front end, makes that the front surface of lock pawl 16 is consistent with the front surface for the treatment of latching segment 47.The rear surface of lock pawl 16 also is inclined upwardly from its rear end to its front end, and can be locked into and treat on the latching segment 47.Lock pawl 16 slightly is narrower than the interval between the beam 46 of lock arm 45.Form locking device puncture space 17 backward from lock pawl 16, locking device puncture space 17 allows the latching segment 47 for the treatment of of lock arm 45 to advance to wherein.Locking device puncture space 17 is upwards open to the outside holes of upper wall 15 of passing cover 14.Therefore, along almost forming locking device puncture space 17 with the direction of the longitudinal direction quadrature of plug casing 11.Form locking device puncture space 17 with shaping mould, when in plug casing 11 time, in shaping mould, upwards pulling out the type heart that is used to make locking device puncture space 17 shapings resin molded.These are different with prior art (Figure 21), and in the prior art, locking device puncture space is vertically to pass the terminal fitting retaining part.Therefore, the present invention can stop water to infiltrate shell C, and plug casing 11 seems very meticulous.As shown in Figure 2, locking device puncture space 17 almost is tetragonal in vertical view.

Shown in Figure 10 and 12, ribs 18 on cover 14 upper wall 15 from locking device puncture space 17 longitudinal extension backward.Ribs 18 inwardly stretches out from the inner surface that covers 14 upper wall 15, makes ribs 18 and lock pawl 16 relative and at the rear of locking pawl 16.The rear end of ribs 18 links to each other with the front surface of terminal fitting retaining part 13.The width of ribs 18 almost equates with those sizes of lock pawl 16 with the distance of inwardly stretching out.The shaping mould that is used to form ribs 18 has the type heart that draws forward of side surface of the ribs 18 that is used to be shaped and one be used to the to be shaped type heart that upwards draws of front surface.Thereby the mould in the locking device puncture space 17 that is used to be shaped is shaped the front surface of ribs 18.

Shown in Fig. 2 and 12, thereby the bight chamfering at the place, both sides of the front surface 18a of ribs 18 is formed tapered guide surface 19.When Socket casing 21 was engaged in the plug casing 11, the inner surface of the beam 46 of lock arm 45 is contact guidance face 19 slidably.Thereby guiding socket connector 20 enters pin connector 10.The width in locking device puncture space 17 increases to its rear end.The taper ratio spigot surface 19 of the side surface 17a in locking device puncture space 17 relaxes.The tapered side surface 17a in locking device puncture space 17 and the distance of facing between the spigot surface 19 of side surface 17a are wideer than vertically going up straight side surface 17a and the distance between the spigot surface 19.Therefore, for the part of drawing on the forming model mind-set, between the side surface 17a in locking device puncture space 17 and spigot surface 19, can obtain enough thickness and necessary strength.

Assemble socket connector 20 as shown in Fig. 7 and 8 by in Socket casing 21, preceding keeper 23 being fixed on interim latched position place.Insert each cavity 24 from the rear portion jack terminals joint 22 then.Thereby jack terminals joint 22 extruding armed levers 26, and armed lever 26 strains enter deformability space 27.As shown in Figure 9, when jack terminals joint 22 inserted the cavity 24 preassigned degree of depth, armed lever 26 returned to their reset condition and enters lock hole.Correspondingly, thus the week that each armed lever 26 is locked into lock hole 24 take out jack terminals joints 22 along last prevention from cavity.Shown in Figure 10 and 11, then preceding keeper 23 is pressed onto main latched position.Thereby strain stops part 38 to enter deformability space 27 to stop the strain of armed lever 26.Thereby jack terminals joint 22 is remained in the cavity 24 with very strong power.

As shown in figure 10, the pin connector 10 that assembles is fixed on the interior substrate K of shell C.Then, socket connector 20 is coupled in the pin connector 10 of shell C outside.More specifically, guiding rib 50 advances among the gathering sill 14a, thereby and protective bulkhead 49 advance among the receiving channel 15a guiding Socket casing 21 and enter cover 14.Shown in Figure 13 and 14, in this process, lock pawl 16 and ribs 18 advance in the space between the beam 46.At this moment, spigot surface 19 is sentenced the inner surface that mode slidably contacts beam 46 in the Width end of the front surface 18a of ribs 18.Thereby socket connector 20 is coupled in the pin connector 10 smoothly, and ribs 18 can not hook Socket casing 21.When socket connector 20 enters pin connector 10 desired depths, treat that the front surface of latching segment 47 slidably contacts the front surface of lock pawl 16.Therefore, as shown in figure 15, treat that latching segment 47 is depressed, and lock arm 45 downward strains.

Shown in Figure 16 and 17, when making the preassigned degree of depth that two matching surfaces contact with each other in Socket casing 21 is coupled to plug casing 11, lock arm 45 recovers its reset conditions.Therefore, treat that latching segment 47 advances in the locking device puncture space 17, thereby and the rear surface in locking device puncture space 17 be locked on the rear surface of pawl 16

housing

11,21 kept together.At this moment, plugs terminals joint 12 and jack terminals joint 22 are electrically connected.Whole ribs 18 advances in the space between the beam 46, makes that the front surface 18a of ribs 18 is relative with the front surface for the treatment of latching segment 47.In this standard mated condition, finger tabs 51 separates with predetermined space with the front surface of cover 14, makes the operator can catch finger tabs 51 to separate

housing

11,21.

As mentioned above, locking device puncture space 17 be one along with the direction hole open that the cooperating of socket connector 20/detaching direction intersects to the outside.Therefore, the lock pawl 16 at the place, rear portion in ribs 18 and locking device puncture space 17 is relative, and along extending to improve the intensity of cover 14 with the cooperating of socket connector 20/detaching direction.Locking device puncture space is open backward along the cooperation/detaching direction of socket connector 20 in traditional structure (seeing Figure 21), and can not form reinforcement in the zone of locking device puncture back, space.On the other hand, the design of the connector of above-mentioned first embodiment has the very high degree of freedom.Space between two beams 46 of lock arm 45 is a dead band that ribs 18 is entered.This with ribs 18 wherein in other position and must provide one to be used to admit the design in the space of ribs to form contrast to socket connector.Therefore socket connector 20 is simplified.

Place, two Width ends at the front surface 18a of ribs 18 all further forms spigot surface 19.Therefore, spigot surface 19 guiding socket connectors 20 enter cover 14, and ribs 18 can not block Socket casing 21.

Gap between the side surface 17a in spigot surface 19 and locking device puncture space 17 is narrower.Therefore shaping mould the be shaped part of spigot surface 19 of locking device puncture space 17 and being used to that is used to be shaped is narrower, and worry these parts can intensity a little less than.But locking device puncture space 17 broadens gradually to spigot surface 19.Therefore, between the side surface 17a in spigot surface 19 and locking device puncture space 17, have bigger gap, and shaping mould be used to the to be shaped part of locking device puncture space 17 and spigot surface 19 has enough intensity.

Below with reference to Figure 18 to 20 second embodiment of the present invention is described.The longitudinal size of considering the cover 14 of plug casing 11 may change, and the Socket casing 21 of second embodiment has block 52.The structure of second embodiment, operation and effect are similar to first embodiment, do not describe below.Not shown shell C in Figure 19 and 20.

As shown in figure 19, cover 14 is longer than the socket connector 20 that is suitable for first embodiment.Therefore when socket connector 20 was coupled to standard depth described in the pin connector 10, pin connector 10 separated with predetermined space S (seeing Figure 20) with the matching surface of socket connector 20.When manufacturer makes pin connector 10 and another manufacturer when making socket connector 20, the length of cover 14 might change.Shown in Figure 18 and 19, two blocks 52 stretch out length of fit with restriction Socket casing 21 downwards from the lower surface of Socket casing 21.Block 52 separates with predetermined space on the Width of Socket casing 21.The rear end of each block 52 all is connected with finger tabs 51.The front surface of block 52 is vertically upright.

When socket connector 20 when state shown in Figure 19 is pressed into pin connector 10 forward, lock arm 45 strains.But as shown in figure 20, when Socket casing 21 was coupled in the plug casing 11 the preassigned degree of depth, lock arm 45 recovered its reset conditions.Therefore, treat that latching segment 47 advances in the locking device puncture space 17, and be locked on the pawl 16.At this moment, pin connector 10 does not contact with the matching surface of socket connector 20, and forms gap S between them.Therefore, can worry to push socket connector 20 forward and surpass the preassigned position and may influence two terminal fittings 12,22 connected to one another unfriendly.But, when Socket casing 21 is coupled in the plug casing 11 the preassigned degree of depth, the front surface of the front surface of two blocks 52 of Socket casing 21 bump cover 14 bottoms, and stop compounding practice to be proceeded.Therefore, socket connector 20 can excessively not advance in the cover 14, and can influence terminal fitting 12 and 22 sharply.

The invention is not restricted to the foregoing description with reference to the accompanying drawings.For example, the following example is included in the technical scope of the present invention.Further, need not to depart from the spirit and scope of the present invention and just can make various improvement these embodiment.

Spigot surface on two Width ends of ribs front surface may be a for example circular arc of curved surface, rather than above-mentioned conical surface.Further, can remove this spigot surface from ribs.

The structure in locking device puncture space can change as required.For example, the width in locking device puncture space needn't broaden gradually to spigot surface.

The present invention can be applicable to a kind of connector that is not fixed on substrate or the shell.

The number of plugs terminals joint and jack terminals joint can change as required.The structure of lock arm also can change as required.
