Description

The connector that has contact guide member

The present invention relates to a kind of connector, more specifically is to have the sort of connector of a guide member with the unlikely bending of protection male contact.

Connector is equipped with guide member in their shell be a known technology with the unlikely bending of protection male contact.An example of this connector is disclosed in, for example, Japanese Utility Model prospectus 63(1988) on-No. 116985, hereinafter will be described referring to Figure 16 and 17.

Figure 16 shows a female type and the plug connector longitudinal cross-section figure before joint.And on the other hand, Figure 17 has shown two the longitudinal cross-section figures of connector under engagement state.

In the shell 212 of female type connector 210, be mounted with a plurality of male contacts 214.The front end 214a of each male contact 214 passes a corresponding through hole in the guide member 216, and this guide member is locked together in by overhangs that are formed in the shell 212 in the recess 216a of guide member 216 and maintenance for the moment rests in the shell 212.When female type connector 210 and plug connector 220 engage one another, guide member 216 is promoted to move on to the rear end part of male contact 214 by plug connector 220, thereby having formed male contact 214 is engaging between the female contact with corresponding socket, as shown in Figure 17.

As mentioned above, the front end of male contact is inserted in the through hole in the guide member of the connector that disposes this guide member and just can protects the unlikely bending of male contact effectively.On the other hand, when plug type and female type connector join when indivedual, guide member by plug type connect promote to move on to male contact the rear end partly.

Also have this situation, promptly two kinds of connectors 210,220 engage more than once and throw off.Still rest on later the rear end partly if 216 two connectors of guide member are thrown off, male contact or contact stud 214 promptly can not get protection, thereby may be applied to the external force institute bending at this place before row engages again with pieceable connector.In order to address this problem, disposed extra device in the connector of prior art, as shown in Figure 18.

Latch arms 234 can be engaged in when being arranged in the plug connector 220 and engaging with two connectors of box lunch 210,220 in the interlock hole 230 on the end wall 218 of a guide member 216.When plug connector 220 was thrown off, guide member 216 was drawn back into its original position as shown in Figure 18 (A).When two connectors engaged, latch arms 234 withstood on one and passes a guide plate partly on 217 the pressure strip 232, thereby forms reliable interlock with interlock hole 230.Pressure strip 232, latch arms 234 and interlock hole 230 cooperatively interact, thereby as long as when female type connector 210 and pieceable connector are thrown off mutually, guide member 216 rests on the origin-location all the time so that protect contact stud 214 effectively.

Guide member normally temporarily is held stop in the enclosure with a faint power; thereby the protected unlikely bending of the front end that makes male contact or keeping normal alignment, wait until when two plug types and female type connector become engagement relationship always till.Its reason is such, if when the power that keeps is too powerful, two connectors just are difficult to it is bonded with each other.Consequently, in the ordinary connector that has guide member, produced a problem, promptly in connector carrying, if be given a shock or be by accident any thing collision, guide member will unexpectedly shift to male contact from the front position that fastenes rear end partly.

Also have, the pressure strip 212 of prior art connector and the application of latch arms certain space that accounted in the enclosure, thus limited the high density setting of contact.In addition, latch arms 234 is stretched out suitable length from guide member 220, thereby when its coverlet stayed alone that when reason, connector was not engaged, latch arms 234 was just fractureed probably or otherwise causes distortion.

Therefore an object of the present invention is to make guide member to keep securely resting on its position because the accident that vibrations or other power cause moves to avoid, wait until when plug type and female type connector engage always till.On the other hand, when connector was engaged, the temporary transient stop of guide member must be easy to release out so that connector can successfully engage.

Another object of the present invention provides the connector of a high density contact, and it has a solid guide member that is used for male contact, and when not engaging, guide member is just got back to its original position.

Guide member according to connector provided by the present invention comprises:

First connector with one first shell, male contact are positioned in this first shell and towards the direction that engages and extend;

Second connector with one second shell, its second shell engages with first shell; With

One has a plurality of guide members that therefrom pass the through hole of male contact, and guide member is pushed into the rear end of male contact by second connector when described first and second connectors engage; And it is characterized in that:

The overhang that (1) first shell has on the wall within it is positioned at the front end position more forward than male contact;

(2) guide member have by the elastomeric spring that extends towards direction of engagement partly and the leg that partly forms of buckle so as by with overhang mutually interlock stop guide member partly mobile to the rear end of male contact; With

(3) second shells have the overhang of promotion so that release out interlock with leg, and overhang partly makes partly displacement of spring by promoting buckle when first and second shells engage.

The connector of another kind of mode comprises the guide member that a female type insulation crust with a depression of admitting a plug connector in it and move along the direction of engagement of plug connector in depression according to the present invention, guide member has a guide plate partly, be formed with a plurality of perforates extend in the bullet connector in the depression with guiding contact part on it, with with the plug connector latch arms of interlock mutually, it is characterized in that guide member has the side plate that extends to direction of engagement from guide plate edge part partly and latch arms is extended towards opposite direction from the direction that free end to the side plate of side plate extends.

In Fig. 1, electric connector comprises a plug connector 10 and a female type connector 40, and both utilize one to be contained in the screw rod 110 that nut (not shown) on the plug connector 10 and is contained on the female type connector 40 they are engaged one another.Plug connector 10 has one and is generally rectangular insulation crust 12, is formed with on it among a large amount of jack 18(Fig. 1 only to demonstrate the minority jack) 16 extend towards relative composition surface from its contact inserting surface 14 so that the female contact (not shown) is received in it.Being inserted into from two opposite side surfaces 20,22 in the insulation crust 12 is two locking pieces 24,25 in case detent plug hole contact is drawn out.Female contact is blocked by the common compressor arm (not shown) that is formed in the jack 18, is also pinned in pairs by locking piece 24.An angle of locking piece 24 is formed by a domatic face 26.Kindred circumstances, another locking piece 25 also is formed with a domatic face 28 in its mirror image position, and is shown in dotted line.Domatic Figure 26 at diverse location of two locking pieces 24,25,28 have played positioning action.In this case, locking piece 24 can not be inserted in the locking piece patchhole (not shown) on the opposite side surface 22, and under the kindred circumstances, and another locking piece 25 can not be inserted in the locking piece patchhole 30 on the side surface 22.Should be noted that positioning action might not reach with the domatic face, other shape, as L shaped hole, arcwall face or the like also can use.

Female type connector 40 has a socket insulation crust 42 and enters in a large amount of jack 44 to admit tongue piece (connector) contact (not shown).There is one in the insulation crust 42 by four sidewalls 48,50,52 and the 54 joint depressions 46 that limit.Be formed with on the opposite flank 56,58 of insulation crust 42 and be used for admitting locking piece 60(only to show one of them) locking piece patchhole 62(figure only show one of them hole) be not drawn out with protection tongue piece contact.Equally on the locking piece 60 also be formed with a domatic face 61 with locking piece 24.The size that please notes locking piece 60 is different with locking piece 24, thereby can avoid the mistake of operator's fit on, even because the operator so does intentionally, locking piece 60 can not be allocated the locking piece patchhole 30 on the plug connector shell 12 into.Kindred circumstances also can not cooperate even locking piece 24 is inserted in the locking piece patchhole 62 on the female type connector shell 42.By being that connector 10,40 all is symmetrical, therefore be difficult to determine the direction or the trend of joint.Yet they can be recognized by color-coded.For example locking piece 24,60 can be a black, and then can be yellow with respect to the locking piece of locking piece 24,60.

From its basal surface extension in the depression 46 of female type connector shell 42 is that a sleeve member 64 and a plurality of post 66(have four posts among the embodiment that shows).Sleeve member 64 is the screw parts that encase and protect screw rod 110.Also have, sleeve member 64 and post 66 are longer than the partly (not shown) that contacts of the tongue piece contact that extends from the basal surface of depression 64, thereby the contact of protection tongue piece contact partly is not subjected to the influence of plug connector 10 swings (or " Kojiri ").

Guide member 70 is to be contained in such a way in the depression 46 of insulation crust 42, promptly slips into along the sidewall 46,48,50,52 that limits depression 46.As shown in Figures 1 to 3, guide member 70 has one to be roughly the guide plate 72 of rectangle and 74,76 to extend and to be approximately perpendicular to partly 72 side plate 78,78 of guide plate from two relative edges.Be formed with among a large amount of hole 84(Fig. 1 on the guide plate part 72 and only show a few hole) extend to rear surface 82 from front surface 80, its quantity and position are equivalent to the jack 44 on the insulation crust 42.The effect of through hole 84 is unlikelyly to be out of shape as ordinary or to fracture.Also have, be formed with sleeve patchhole 86 and post patchhole 88 on the guide plate part 72.Guide plate partly the approximate center of 72 rear surface 82 be formed with rib 90 and in Fig. 2 (A), vertically extend between two limit levels 74,76.Traverse guide plate partly 72 rib 90 partly 72 mechanical strength is provided and reduces its deflection or reverse for guide plate.

The side plate 78,78 of guide plate 70 with equidirectional extension, therefore makes its cross section form by 72 and two roughly U-shapeds that side plate 78,78 is limited of guide plate part, shown in Fig. 2 (B) from two opposed edges 74,76.This structure and above-mentioned rib 90 help to improve the mechanical strength and the protection unlikely deflection of guide plate of guide plate part 72 and reverse.What extend from the free end of each side plate 78 towards the rightabout with side plate 78 is a plurality of flexible 92,94,96.Therefore, each flexing arm 92,94,96th, cantilever shape, its stiff end is installed in that side plate 78 extends.With arm 92,94,96 directly partly 72 extend and compare from guide plate, arm from guide plate partly the length on 72 surface 80 to lack the length of side plate 78.This helps at female type connector 40 not (Fig. 1) or (do not have a connector to be assembled together) individually to reduce the distortion of arm 92,94,96 when moving guide member 70 or fracture in the engagement state.In addition, because arm 92,94,96 is formed in the end portion of side plate 78, just there is no need to reduce the quantity of contact jack, and arm is contained in the protection that also is subjected to sidewall 48,52 in the insulation crust 42 effectively.Also have, arm 92,94,96th is connected on the guide plate part 72 by having flexible slightly side plate 78, therefore compare with the arms that directly extend from guide plate part 72, flexible length has just increased, and has avoided arm 92,94,96 stress is concentrated, and has also improved arm 92,94,96 durability simultaneously.Guide posts 98 is integrally formed on the side plate 78 near two side place.Guide posts 98 help guide members 70 to move smoothly and not can with respect to the contact of tongue piece joint partly the bearing of trend of (not shown) form crooked.

In guide member 70 home position as shown in Figure 3, the sidewall 48(52 that the front end of U-shaped the 3rd arm 96 leans at insulation crust 42) on the 3rd overhang 104 on, thereby prevented that guide member 70 from deviating from from insulation crust 42.In addition, a pair of inside that is roughly L shaped the first arm 92 partly 92a leans at sidewall 48(52) front end of last first ledge 100 is partly on the 100a, prevented that guide member 70 from moving into (in Fig. 3 for downward) to depression 46.The first arm 92 partly is being formed with domatic face 92b on the 92a in inside so that lean at the front end of first overhang 100 partly on the corresponding domatic face 100b at 100a place, thereby prevented that the first arm 92 is from departing from the sidewall 48(52 on the insulation position shell 42) direction deflection.The direction that the inside part 92a of the first arm 92 extends not is the surface perpendicular to sidewall 50, but oblique slightly in front panel 72.Also have, partly 100a is oblique similarly for first overhang, 100 front ends.The inside that tilts partly 92a and front end partly 100a keep and the engaging of first overhang 100, unless the external end head of the first arm 92 partly 92c engaging the overhang that is roughly rhombus 32 of plug connector 10.

When plug connector 10 enters in the depression 46 of female type connector 40, arrange the first arm 92 is deviate from from first overhang 100 thereby a pair of the first arm 92 is roughly the outside partly joint between the 92c of the overhang 32 of rhombus and the first arm 92.At the same time, provide the temporary transient combination of two connectors 10,40 at the joint between the overhang in sidewall 50,54 inner groovies of overhang on the side surface 20,22 of plug connector 10 34 and female type connector 40.At two connectors 10, in 40 the temporary transient combination, the inertia that leans the guide member 70 on the female type connector 40 in going into may just move to the position of stepping back with guide member 70 before tongue piece contact (not shown) in the plug connector 10 and socket (or consent) contact formally engage.In this case, because the collision on the composition surface 16 of receptacle contact or plug connector, the tongue piece contact is not supported fully and guides.For this is taken place, second arm 94 that is roughly U-shaped of guide member 70 leans on the taper face 102a of second overhang 102 on the sidewall 48, thereby has prevented that guide member 70 from moving individually.That is to say, after the first arm 92 and first overhang 100 are released out by the overhang that is roughly rhombus 32 of plug connector 10, guide member 70 retreats slightly, just the direction with arrow E among Fig. 3 moves, and temporarily stops to move owing to second arm 94 withstands at taper Figure 102 of second overhang 102 a.Subsequently, the driving that is subjected to screw rod 110 and nut (not shown) owing to plug connector 10 is resisting interlock between second arm 94 and second overhang 102 when moving on, and second arm 94 is crossed second overhang 102 makes guide member proceed to the most far-reaching position of depression 46.Guide member 70 moves to the most far-reaching position from its home position because the cooperating of post guiding part 108 of slip between arm 92,94,96 and the sidewall 48,52 and guide posts 98 and female type connector 40 is very level and smooth.At two connectors 10, in 40 the temporary transient bonding state, the first arm 92 is crossed the overhang that is roughly rhombus 32 of plug connector 10 and is engaged on its domatic face 32a (Fig. 1), thereby make guide member 70 when plug connector 10 is deviate from, can move forward (direction of arrow F in Fig. 3), hereinafter will give narration this.

When screw rod 110 rotates with opposite direction when deviating from the female type connector 40 that makes plug-in connector 10, guide member 70 is because the first arm 92 is being followed plug connector 10 with the interlock between the overhang 32 accordingly moves forward.It should be noted that be guide member 70 can move forward with comparalive ease be because the first arm 92 and second arm 94 respectively with first and second overhangs 100,102 the sloping 100c and 102b interlock mutually that relatively relax, thereby can cross first and second overhangs 100,102.When guide member 70 arrives the home position, as shown in Figure 3, guide member 70 is blocked on the 3rd overhang 104 owing to the 3rd arm 96 withstands on and moves forward, thereby the first arm 92 is disengaged from the overhang 32 of plug connector 10, and plug connector 10 is separated from female type separator 40.This a plurality of arm can remain on its home position with making guide member 70 cooperating of overhang, can move forward and prevention is drawn out.Can notice that guide member 70 can be deviate from an easy rate from female type connector 40, just can as long as form instrument insertion groove 97,104 in position near the front end of the 3rd arm 96 and the 3rd overhang 104.

Shown in Fig. 4 is the cross-sectional view of the female type connector that assembles of a width of cloth.With reference to figure 1 and 4, female type connector 40 if desired, can also comprise that a screw rod keeps shell 120 and also has a wire cover 130.Screw rod keeps shell 120 by the joint between the first step part (or claiming shoulder) 114 of elastic arm 124 and screw rod 110 screw rod 110 to be remained in its passage 122.Screw rod 110 be inserted into one with the sleeve of female type connector shell 42 perforate 64(Fig. 1 partly) in the screw rod receiving opening (not shown) that communicates.Screw rod 110 and screw rod maintenance shell 120 engage with a second step part 116 of screw rod 110 by the metal fixture (not shown)s that is embedded in the shell 42 and are installed on the shell 42.Screw rod keep being formed with on the shell 120 a known independent indicating device 124 with the screw that prevents screw rod 110 partly 112 and shell 120,42 because excessive rotation or screw rod 110 fastening and fractureed or break.

Wire cover 130 is to be used for extending the electric wire (not shown) from the electric wire inserting surface 68 of female type connector shell 42 with predetermined direction.Wire cover 130 be provided with four breech lock pawls 134 in order to by with the side surface 56,58 of socket or connector shell 42 on four engage two that only demonstrate among overhang 69(Fig. 4 wherein) thereby engage and be clamped on the female type connector shell 42.Also be formed with a cylindrical shape down on the wire cover 130 partly 136 in its position at center basically.When wire cover 130 was installed on the female type connector shell 42, cylindrical shape partly 136 diameter just in time can be nested in the cylindrical flange 126 that the spiral shell fourth keeps shell 120.Being nested in of cylindrical shape part 136 helps to make any electric wire (not shown) from electric wire inserting surface 68 to leave partly 136 opening 138 of cylindrical shape on the cylindrical flange 126.Like this, the impact type impact wrench that rotates of the head 118 of routine screw rod 110 or other instrument (not shown) are just protected effectively and are unlikelyly twined for shown in the electric wire.

Described hereinafter with reference to Fig. 5 to 15 couple of another embodiment with connector of guide member.Fig. 5 to 11 has shown the process of cross-sectional view to illustrate that connector engages of the skeleton diagram and the guide member of chock plug shell.

At first, referring to Fig. 5, this is a structure of describing the connector with guide member.The cover housing 40 that has that the connector 30 of guide member ' comprise prepares to be bonded with each other and chock plug shell 50 '.Cover housing 40 ' in have a plurality of male contacts 42 '.Be contained in cover housing 40 ' interior also have a tabular guide member 60 ', be parallel on the guide member base is flat cover housing 40 ' the composition surface.Guide member 60 ' on be formed with a plurality of male contacts 42 of a plurality of through holes 61 ' be equipped with ' therefrom pass.

A pair of surperficial 43a ' with the direction of engagement of being substantially perpendicular to be formed on cover housing 40 ' diapire 44 ' on, thereby overhang 44a ' joint a pair of be formed on guide member 60 ' on L shaped leg 60a ', its face 63a is perpendicular to direction of engagement.This joint is based upon two face 43a ' that are substantially perpendicular to direction of engagement, the butt joint of 63a ', thereby protected because the guide member 60 that vibrations or other power cause ' shifted to suddenly male contact 42 ' rear end.On the upper surface of overhang 44a ', partly be formed with a downward slope, thereby connector is deviate from easily from its center to back.Also have, cover housing 40 ' diapire 44 ' on be formed with two overhang 44b ', thereby guide member 60 ' braking leg 60b ' lean at overhang 44b ', with prevent guide member 60 ' from cover housing 40 ' in fall out.In addition, cover housing 40 ' diapire be provided with two overhang 44c ', come on the face from central division thereon part to forward and have downward slope on the direction backward.In addition, overhang 44c ' temporarily stopped guide member 60 ' move directly wait until chock plug shell 50 ' when slightly with cover housing 40 ' when engaging by chock plug shell 50 ' run into guide member 60 ' temporary transient braking leg 60c ' withstand guide member 60 ' benchmark and face 62 ' on the time till.This arrangement avoided effectively lid outer 40 ' in male contact 42 ' and chock plug shell 50 ' in the female contact (not shown) between collision, thereby guaranteed positive engagement between the contact.In addition, cover housing 40 ' diapire on also have two overhang 44d ' so that L shaped leg 60d ' departs from, hereinafter will be described in detail.Please note overhang 44a ' to 44d ' (not shown) be formed on cover housing 40 ' upper wall on.

Also have, chock plug shell 50 ' on be formed with wedge projection part 50a ' in case by move it enter between the L shaped leg 60a ' with their mutually skew come and release out interlock between L shaped leg 60a ' and the overhang 44a '.In addition, the formation of overhang 50b ' is in order to make guide member 60 ' move when the male contact 42 ' lock microbend smooth-goingly.

To describe below connector 30 ' engaging process.As shown in Figure 5, cover housing 40 ' and chock plug shell 50 ' unassembled situation under, overhang 44a ' and L shaped leg 60a ' by cover housing 40 ' the face 43a ' of overhang 44a ' and the reliable applying between the face 63a ' of L shaped leg 60a ' and male contact 42 ' the direction of rear end on interlock firmly.This can avoid guide member 60 ' by accident towards male contact 42 ' the rear end move.Other direction, braking leg 60b ' withstand on cover housing 40 ' overhang 44b ' go up with prevent guide member 60b ' from cover housing 40 ' fall out.Also have, cover housing 40 ' and chock plug shell 50 ' unassembled situation under, male contact 42 ' front end protected be not subjected to the infringement of external force because they do not stretch out through hole 61 ' outside.

As shown in Figure 6, when cover housing 40 ' and chock plug shell 50 ' when engaging one another slightly, chock overhang 50a ' more in depth moves between the pair of L-shaped leg 60a '.When cover housing 40 ' and chock plug shell 50 ' further engage, more in depth the paired L shaped leg 60a ' of shift-in is interior just in time on overhang 44a ' for chock overhang 50a ', thereby largely paired L shaped leg 60a ' is arranged mutually, as shown in Figure 7.When cover housing 40 ' and chock plug shell 50 ' further engage, interlock between overhang 44a ' and the L shaped leg 60a ' is just released out, and guide member 60 ' because the linking mutually between temporary transient stop leg 60c ' and the overhang 44c ' and temporarily breaking off an action, as shown in Figure 8.

Shown in Fig. 9 be cover housing 40 ' with the situation of chock plug shell 50 ' when further engaging, guide member 60 is because the linking mutually between temporary transient stop leg 60c ' and the overhang 44c ' and temporarily breaking off an action at that time, but chock plug shell 50 ' near guide member 60 '.Cover housing 40 ' and chock plug shell 50 ' further engage make chock plug shell 50 ' lean guide member 60 ' basic 62 ' on, as shown in Figure 10.Just in this case, male contact 42 ' with the female contact (not shown) of meeting, thereby provide smooth-going the joining of contact to avoid the collision of connector contact.When chock plug shell 50 ' run into guide member 60 ' and joint work when still proceeding, temporary transient stop leg 60c ' with regard to crossing overhang 44c engaging between male contact 42 and the female contact (not shown) reached fully, as shown in Figure 11.

For make male contact 42 ' and the female contact (not shown) be disengaged or cut off, chock plug shell 50 ' just is by towards (uncoupling) direction pulling opposite with direction of engagement.Then, chock overhang 50a ' and paired L shaped leg 60a ' join and make guide member 60 ' move towards the uncoupling direction.When chock plug shell 50 ' further when the uncoupling direction is drawn back, paired L shaped leg 60a ' crosses overhang 44a ', simultaneously temporary transient stop leg 60c ' crosses overhang 44c '.When chock plug shell 50c ' was further drawn back, overhang leaned on stop leg 60b ' the mobile of guide member is stopped, thus make chock plug shell 50 ' from cover housing 40 ' deviate from fully.

Now, referring to Figure 12 to 15 so that describe the engaging process of connector 30 ' in such a case, promptly for example male contact 42 ' (see figure 5) slightly a bit crooked with protrude into through hole 61 ' in, thereby hindered guide member 60 ' level and smooth moving.

What Figure 12 was shown is a kind of situation, wherein male contact (not shown) slight curvature protrude into through hole 61 ' in hinder guide member 60 ' level and smooth moving.Make comparisons with Fig. 5, chock plug shell 50 ' be bonded on cover housing 40 ' interior dark clearly, but the mobile of guide member 60 is restricted.As shown in Figure 13, if the mobile restricted system of guide member 60, when cover housing 40 ' more in depth and chock plug shell 50 ' when engaging, overhang 50b ' just lean guide member 60 ' L shaped leg 60d ' on.When further engaging, L shaped leg 60d ' is highlighted partly that 50b ' institute pushes open again, as shown in figure 14, thereby make guide member 60 ' towards direction of engagement mobile slightly and impel male contact 42 ' front end more in depth enter into through hole 61 ' in.When joint is proceeded, domatic face 63a ' quilt sloping 45a ' of overhang 44d ' on cover housing 40 ' inwall of L shaped leg 60d ' is substantially perpendicular to direction of engagement and promotes, as shown in Figure 15.This has just eliminated conflicting between overhang 50b ' and the L shaped leg 60d ', as shown in Figure 13.Joint work is proceeded as shown in Figure 14 and 15 to finish joint.Even if this illustrate some microbend of connector 30 ' male contact of the present invention protrude into by 61 ' in, also can make guide member 60 ' move to finish normal joint smoothly.

Certainly in above-mentioned preferable enforcement, leg 60a ', 60b ' they also can be T shapes, other shape J-shaped or any, and might not be L shaped.In addition, in first embodiment, the first arm 92 can make into plug connector 10 on groove rather than with overhang 32 interlock mutually.

Connector of the present invention is suitable for high contactor density, because the latch arms of guide member is not disturbed contact.Latch arms begins to stretch out the minimum length in guide member surface from the relative edge of guide member side plate, and enough elasticity still can be provided, thereby when connector is released out or the chance of working as guide member or fractureing.Guide member provides the mechanical strength that increases by having added side plate to reversing or being out of shape, thereby has improved the guiding operation.

In addition, the connector that has guide member of the present invention moves the protection that improvement is provided to guide member owing to the accident of vibrating or other external force causes, this is because due to the reliable interlock of overhang in the leg of guide member and first shell.When first and second shells engaged, the interlock between leg and the overhang was easily second shell and releases out, and it promotes guide member just can easily make first and second shells engage.
