Description
Technical field
The present invention relates to a pair of connector that is connected with each other and relate to a kind of latch-up structure.
Background technology
Known traditionally a kind of electrical connector, this electrical connector lock arm by a connector and the joint of the locking protuberance of another connector are locked in the correct state that is connected (referring to, the open No.2005-183342 of Japanese laid-open patent for example).The front end of lock arm is as the junction surface that can engage with the locking protuberance, and during the attended operation of two connectors, the junction surface moves on this locking protuberance so that the lock arm strain.When two connectors arrived the correct state that connects, the junction surface was moved beyond locking protuberance and lock arm elastic return so that the junction surface engages with the locking protuberance, thus two connectors is locked in the state of correct connection.
In electrical connector above, between junction surface and locking protuberance, limit a specific gap, in order to avoid when the lock arm elastic return, the junction surface is interfering with each other with the locking protuberance.Therefore, when connector stands vibration etc., may have recoil between locking protuberance and junction surface, the possibility of result produces abnormal sound or terminal may slide relative to one another and be worn.Particularly, use in high temperature and high vibration environment in the situation of electrical connector, the gap between locking protuberance and the junction surface may be owing to the deformation of creep enlarges.Therefore, need deal with the countermeasure of recoil.
In addition, known a kind of for example disclosed latch-up structure in the open No.H01-98485 of Japanese Utility Model, this latch-up structure is used for by spring a pair of member being locked in the state of correct connection.Spring comprises the displaceable leg section of a pair of elasticity and vertically is installed on the housing of connector displaceablely, and this housing is formed with passage, is arranged on the locking protuberance that cooperates on the housing and passes in described passage.When housing correctly is connected with the cooperation housing, the leg section of spring stretches in the passage and is positioned at the back (with the detaching direction that cooperates housing) of locking protuberance, and two connectors are locked in the correct state that is connected by the joint of leg section with the locking protuberance.
When two connectors in the state that will be locked in correct connection separate, by downwards by pressing spring so that leg section retracts the state of unlocking from passage.
In structure above, must be by finger tip directly downwards by pressing spring (being unlocking operation).Because spring is thinner than finger tip, so there is the problem of poor operability.
If finger tip is placed enough spaces on the spring because the shape of matching connector (for example matching connector comprises the wall portion more outstanding than spring) and can not guaranteeing has, then unlocking operation must use anchor clamps to wait to carry out, and this existence need be used for the work of unlocking operation and the problem of time.
In addition, in latch-up structure above, spring may dislocation and the state that unexpectedly unlocks, for example, if electrical connector uses in the environment of height vibration.Yet for the state of unlocking, spring must be in displaceable state to a certain extent.Therefore, need countermeasure.

Spring 50 (preferably complete substantially) remains on the first location wall 32 and front wall portion 43, second is located between the wall 33 preferably unqualified substantially in the forward and backward directions gap.In being arranged so that on the displaceable scope of spring 50 between insertion position IP and retracted position RP, the height of the first location wall 32 and the second location wall 33 remains between the first location wall 32 and the second location wall 33.
Be used for when being pressed, pushing this press section 42 separate that rearward end (other end) that lock section 45 is arranged on unlocking arm 39 is located or near.The lower surface of separating lock section 45 is towards the rear end outside or be inclined upwardly (thickness that preferably reduces to separate lock section 45).The inclination of the lower surface by separating lock section 45 and the back recess 38 of cloudy housing 21 are guaranteed or enough downward elasticity dislocations of separating lock section 45 are provided, and have suppressed the height of cloudy housing 21 simultaneously.
When unlocking arm 39 in the raw the time, spring 50 is held or is positioned at insertion position IP, and cloudy housing 21 is in the state that is lockable in the cloudy housing 11.This moment, the state of unlocking arm 39 was called the lockable state.Separate lock section 45 so that unlocking arm 39 when tilting when pushing, press section 42 is extruding or dislocation spring 50 upwards or outwards, and spring 50 towards or to retracted position RP dislocation, promptly the lock-out state with positive housing 11 is cancelled.This state of unlocking arm 39 is called released state.
The department of assembly 27 of female connector 20 is formed with one or more skewed surfaces 46, and described skewed surface 46 tilts with the width that reduces department of assembly 27 towards rear side (dorsal part) (tilting along the direction near terminal accommodating portion 23).Skewed surface 46 is formed on the interior perimeter surface of outer tube part 24 (surface of terminaloriented accommodation section 23).Skewed surface 46 is formed on the rear end side of department of assembly 27, more specifically the position before tight from connecting portion 26 towards or in the outer tube part 24 of the approaching position that is assemblied in sealing ring 28 front ends in the terminal accommodating portion 23 in the scope of perimeter surface.Preferably in whole substantially week upwards (particularly, upper and lower a, left side and right hand edge portion do not comprise four angles), skewed surface 46 all basically forms on the interior perimeter surface of outer tube part 24, to reduce the size of department of assembly 27 along vertical and/or horizontal direction.Preferably the width (distance between skewed surface 46 and the terminal accommodating portion 23) of the rear end of department of assembly 27 is set to thickness less than the leading section of the preceding receiver 13 of positive housing 11.Therefore, when two connectors 10,20 arrive the state of correct connection, before the front end of preceding receiver 13 arrives the rear end of department of assembly 27, before basic formation of receiver 13 with skewed surface 46 contact, (closure of edge and female connector 20 is forward) defines the gap before preceding receiver 13 thus.
The leading section (basically forming the part that contacts with the skewed surface 46 of female connector 21) of preceding receiver 13 is formed with one or more inclined surfaces 17, the inclination basically identical of described inclined surface 17 and described one or more skewed surfaces 46.Preferably make progress in whole week substantially, inclined surface 17 all is formed on the outer surface of preceding receiver 13.Inclined surface 17 front end of receiver 13 in the past is outward-dipping towards rear side, and/or the leading section of preceding receiver 13 is because inclined surface 17 and being tapered towards front end.To keep closely contacting with the part of perimeter surface in the inclined surface 17 corresponding preceding receivers 13 with sealing ring 28.
The joint protuberance 16 of male connector 10 is arranged on the centre position in the forward and backward directions (preferably substantially in the center) of positive housing 11, and/or its height and position is positioned at the vertical centre of positive housing 11 substantially.The front surface that engages protuberance 16 is as straddling surface (ridingsurface) 16A, straddling surperficial 16A is inclined upwardly from the front side towards the rear side appropriateness, make spring 50 easily to move to and engage on the protuberance 16, but and the rear surface of joint protuberance 16 is used as the composition surface 16B that can engage with spring 50.
But composition surface 16B tilt with generation be used for substantially forward (along with the closure of cloudy housing 21 forward) promote to engage the power of protuberance 16, promptly tilt to reduce the outstanding distance of the past receiver 13 when the elastic restoring force that receives leg section 51 (the basic outside along receiver 13 in the past is towards the power of the directive effect of inboard) towards rear side.But the inclination of receiving surface 16B is preferably steeper than the inclination that straddles surperficial 16A, and is limited by the outstanding distance that engages protuberance 16, and this outstanding distance width in the forward and backward directions than spring 50 with regard to size is littler.When two connectors 10,20 arrive the state of correct connection, but composition surface 16B preferably is set to arrive the position towards interconnecting part 37.More specifically, in the state of the correct connection of two connectors 10,20, but the leading edge locus of composition surface 16B overlaps with the leading edge locus of interconnecting part 37 substantially, but and/or whole substantially composition surface 16B be exposed to space outside the outer tube part 24 via interconnecting part 37.By providing skewed surface 46 guaranteeing the gap before preceding receiver 13, but composition surface 16B can be easily with respect to forward and the location of direction backward.For example, basically form in the pattern that contacts in the front end and the rear end of department of assembly of preceding receiver, two housings contact definite with respect to the position of forward and backward directions thus.Yet because in this embodiment, the gap is arranged on before the preceding receiver 13, so can remedy slight error by receiver 13 before inserting forward.
Next, the operation that male connector 10 and female connector 20 are locked in the correct state that is connected is described.Especially, unlocking arm 39 is arranged on the lockable state usually, and/or spring 50 is arranged on insertion position IP usually.
At first, with the cloudy housing 21 of finger grip, and when the passage 36 with respect to 16 pairs of cloudy housings 21 of joint protuberance of positive housing 11 positions, cloudy housing 21 is pushed in the male connector 10 gradually.Then, engage protuberance 16 and in passage 36, move forward, and straddle surperficial 16A and basically form with the junction surface 53 of spring 50 and contact.Further move forward the leg section 51 outside or edge direction elasticity dislocations away from each other of spring 50 along with engaging protuberance 16.At this moment, because the hook portion 44 of unlocking arm 39 is positioned at spring 50 tops, so when the elasticity dislocation of leg section 51, can prevent that spring 50 is moving upward.
Then, 27 rear side inserts the leading section of the preceding receiver 13 of positive housing 11 towards the department of assembly at least in part, preferably pushes or make sealing ring 28 distortion simultaneously.When two connectors 10,20 arrived the correct state that connects, the inclined surface of preceding receiver 13 17 is basic to be contacted with skewed surface 46 formation, anyly further moved forward preventing.In addition, the outstanding end face (but on the surface that straddles between surperficial 16A and the composition surface 16B) that engages protuberance 16 is forward by spring 50, and but leg section 51 is to the small part elastic return and/or keep and be arranged as composition surface 16B Elastic Contact towards interconnecting part 37, and two housings 11,21 are locked to each other together inseparably thus.At this moment, but the junction surface 53 of leg section 51 be pressed against on the composition surface 16B in position near front end.In the state of the correct connection of two connectors 10,20, the inner space of two housings 11,21 preferably by sealing ring 28 and one or more electric wire with elasticity or rubber stopper 47 sealings, and sun and female terminal 12,22 correctly be electrically connected.
If this arrives the correct state that connects by this way to connector 10,20, then the skewed surface 46 of the inclined surface 17 of male connector 10 and female connector 20 is held or is positioned at and is limited to the gap location before the male connector 10 or contacts with this gap substantially, and joint protuberance 16 is pushed forward to keep two connectors 10,20 to be in tight contact substantially by the elastic force of leg section 51.Therefore, if male connector 10 or female connector 20 are owing to (if for example outwards distortion of outer tube part 24) is out of shape in creep etc., then positive housing 11 is promoted forward by the elastic restoring force of leg section 51, and makes moving forward to keep two connectors 10,20 to be in tight contact corresponding to this distortion.Therefore, even the connector of this embodiment 10,20 uses, also can prevent the recoil of two connectors 10,20 in high temperature and/or high vibration environment, the result can prevent the trickle skimming wear of terminal 12,22.
Because two connectors 10,20 preferably keep being in substantially surface contact closely by inclined surface 17 and contacting of skewed surface 46, so can prevent recoil securely.In addition, preceding receiver 13 is pressed against on the outer tube part 24 by the elastic force of the sealing ring 28 of (or being out of shape at preceding receiver 13 and terminal accommodating portion 23 places) between receiver 13 before being squeezed in and the terminal accommodating portion 23.In this way, preferably make progress in whole substantially week, skewed surface 46 keeps being in substantially tight the contact securely with inclined surface 17.
The contiguous first and/or second location walls 32/33 of spring 50 (preferably at least in part between first and second location wall 32 and 33) are installed, so that its dislocation in the forward and backward directions is prevented from, and/or prevent its vertical displacement by hook portion 44.As a result, can prevent recoil between spring 50 and the cloudy housing 21.
Next, the situation that two connectors that will make in the state that is locked in correct connection were opened in 10,20 minutes is described.At first, finger tip is placed on the unlocking arm 39 that is in the lockable state, separate lock section 45 downwards or inwardly to push or to operate.Then, unlocking arm 39 tilts, and press section 42 extrusion springs 50 or make its upwards or outwards dislocation.When spring 50 is extruded or upwards or outwards during dislocation, the last canting 53A at junction surface 53 outwards leads along the upper surface 37A of interconnecting part 37 substantially, leg section 51 strain away from each other thus.At this moment, because the upper surface 37A of last canting 53A and interconnecting part 37 tilts, so leg section 51 can not be blocked when strain, spring 50 can level and smooth dislocation thus.When unlocking arm 39 arrives released states, junction surface 53 be positioned at going up of going up of interconnecting part 37 or outer surface 37A or place, outer end or near, with withdrawal from passage 36 substantially, and engage protuberance 16 and can move backward, state promptly unlocks.Separate lock section 45 by pushing by this way, spring 50 from insertion position IP towards or to retracted position RP dislocation, with basic cancellation lock-out state.Because spring 50 need be by the finger tip direct control, so operability is good.After the cancellation lock-out state, finger is placed on the finger placement section 29 of cloudy housing 21 to hold cloudy housing 21 from opposite side and it is pulled back, separate thus and maybe can separate two connectors 10,20.
If after the lock out operation of two connectors 10,20 is finished, pushing the finger of separating lock section 45 moves apart, then unlocking arm 39 turns back to the lockable state naturally, and the junction surface 53 of leg section 51 utilizes elastic restoring force to be pressed against on the upper surface 37A of interconnecting part 37.Then, junction surface 53 preferably is directed in the passage 36 substantially by the inclination of interconnecting part 37 upper surface 37A, therefore, spring 50 from retracted position RP towards or to insertion position IP dislocation.Therefore, spring 50 preferably only by finger tip is moved apart separate lock section 45 and automatically towards or be provided with to insertion position IP.Therefore, when two connectors, 10,20 after separatings reconnect them, preferably do not need spring 50 is reset to insertion position IP, and can save the connection and the required time and the work of lock out operation of connector 10,20.
As mentioned above, according to this embodiment, when this arrives the state of correct connection to connector 10,20, the skewed surface 46 of male connector 10 and female connector 20 basic be limited to male connector 10 before gap formation contact, but and the leg section 51 of elastic return extruding composition surface 16B, male connector 10 is by (with the closure of female connector 20) extruding or dislocation forward thus.Therefore, even connector 10,20 is out of shape owing to creep etc., positive housing 11 is also promoted forward and is therefore moved forward by the elastic restoring force of leg section 51, and the skewed surface 46 of male connector 10 and female connector 20 keeps in touch.Therefore, can prevent the recoil of two connectors 10,20.
Therefore, for a kind of electrical connector of recoiling of preventing is provided, but but one or more rear surfaces at one or more junction surfaces 16 are used as composition surface 16B, when pair of connectors 10,20 arrives the state of correct connection, but described composition surface 16B is positioned at basic side to the position of interconnecting part 37 and tilt with generation power, is used for promoting forward or another housing 11 of dislocation along the closure with a housing 21 when receiving the elastic restoring force of one or more leg section 51.The department of assembly 27 of second connector 20 is formed with one or more skewed surfaces 46, and described one or more skewed surfaces 46 tilt so that 27 rear side reduces the width of department of assembly 27 towards the department of assembly.Skewed surface 46 and first connector 10 preferably are set to basically form in such position and contact, promptly in this position, along with the closure of second connector 20, before first connector 10, define the gap.

Be used for when being pressed, pushing this press section 127 separate that rearward end (other end) that lock section 131 is arranged on unlocking arm 125 is located or its near.Before connecting rotating shaft 126, the width of separating lock section 131 is preferably than the front portion of unlocking arm 125 wideer (referring to Figure 11), and/or separate the upper surface of lock section 131 rearward end be used toward the acclivitous gradually inclined-plane 132 (referring to Fig. 8) of pushing of rear side.In other words the lower surface of separating lock section 131 towards the rear end outwards or be inclined upwardly, is separated lock section 131 and is preferably shaped to and vertically reduces its thickness towards the rear end.The inclination of the lower surface by separating lock section 131 and the back recess 118 of cloudy housing 110 guarantee to separate enough downward elasticity dislocations of lock section 131, have farthest suppressed the height of cloudy housing 110 simultaneously.
When unlocking arm 125 is in nature or not during deflection state, spring 140 is fixing or be arranged on insertion position IP, and cloudy housing 110 be in can with the state of cloudy housing 150 lockings.This moment, the state of unlocking arm 125 was called the lockable state.Separate lock section 131 so that unlocking arm 125 when tilting when pushing, press section 127 is extrusion spring 140 upwards or outwards, and spring 140 towards or to retracted position RP dislocation, promptly the lock-out state with positive housing 150 is cancelled.This state of unlocking arm 125 is called released state.
Next, the operation that male connector M and female connector F are locked in the correct state that is connected is described.Unlocking arm 125 is arranged on the lockable state usually, and/or spring 140 is arranged on insertion position IP usually.
At first, operation (for example, use finger grip) cloudy housing 110, and when the one or more passages 133 with respect to 155 pairs of cloudy housings 110 of one or more joint protuberances of positive housing 150 position, push cloudy housing 110 among the male connector M gradually or with respect to male connector M dislocation.Then, engage protuberance 155 and in passage 133, move forward, and the front surface that engages protuberance 155 basically forms with the junction surface 143 of spring 140 and contacts.Further move forward along with engaging protuberance 155, the junction surface 143 of spring 140 moves to and engages on the protuberance 155, and leg section 141 outside (along direction substantially away from each other) elasticity dislocation.At this moment, because the hook portion 129 of unlocking arm 125 is positioned at spring 140 tops (or outside), so when the elasticity dislocation of leg section 141, can prevent that spring 140 from upwards promoting.
Simultaneously, when two connector F, M arrive the state (or near connection status) of correct connection, the jag that engages protuberance 155 is towards the preceding spring 140 that passes through, and leg section 141 is to the small part elastic return, but thus junction surface 143 and the composition surface 155A that engages protuberance 155 along forward and direction backward face with each other substantially, so that two housings 110,150 are locked to each other together inseparably.In the state that connects that is in the main true of two connector F, M, the inner space of two housings 110,150 is preferably sealed with elasticity or rubber stopper 136 by sealing ring 115 and one or more electric wire, and sun and female terminal 134,151 correctly are electrically connected.
Next, can divide and open being locked in two connector F, M in the state of correct connection.At first, finger tip is placed on the inclined-plane pushed 132 of the unlocking arm 125 that is in the lockable state, separate lock section 131 downwards or inwardly to push.Then, connection is rotated or pivotal axis 126 rotations or pivot, and plays the strong point, and unlocking arm 125 tilts thus, and press section 127 makes progress or outside extrusion spring 140.When spring 140 by press section 127 upwards or outwards during (or towards retracted position RP) extruding, junction surface 143 is by outer guiding that be tilted to along the upper surface 124A of interconnecting part 124, and leg section 141 strain away from each other.When unlocking arm 125 arrived released states, junction surface 143 was positioned at the upper end of the upper surface 124A of interconnecting part 124, with withdrawal from passage 133 substantially, and engaged protuberance 155 and can move backward, and state promptly unlocks.Then, finger is placed on the finger placement section 116 of cloudy housing 110, separate two connector F, M thus preferably to hold cloudy housing 110 and pull back from opposite side.
As mentioned above because spring does not need to utilize directly dislocation of finger tip, so the operability of unlocking operation is good, and lock-out state can do not need to work and the situation of time under cancel, have nothing to do with the positive housing that cooperates.As a result, can easily carry out the operation of lock-related.
If after the lock out operation of two connector F, M is finished, pushing the finger of separating lock section 131 moves apart, then unlocking arm 125 returns elastically with release and is used for downwards or the inwardly extruding or the power of dislocation spring 140, and junction surface 143 is pressed against on the upper surface 124A of interconnecting part 124 by the elastic restoring force of leg section 141.Then, junction surface 143 is by the inclination of interconnecting part 124 upper surface 124A in the basic introduction channel 133, and therefore, spring 140 from retracted position RP towards or to insertion position IP dislocation.Therefore, spring 140 is preferably only separated lock section 131 and is set to insertion position IP automatically by finger tip is moved apart.Therefore, when two connector F, M after separating reconnect two connector F, M, do not need spring 140 is reset to insertion position IP, and can save and be used for connector F, M are locked in required time of connection status and work again.
Because the preferred lateral deviation that is pressed towards towards spring 140 when the extrusion spring 140 substantially of press section 127 is changeed, so can avoid that spring 140 is from the separation of unlocking arm 125 front ends during unlocking operation, the result can carry out unlocking operation reliably.
In addition because hook portion 129 preferred arrangements of unlocking arm 125 are above the upper lateral part 142 of spring 140, so upwards (away from the direction of the cloudy housing 110) dislocation that can prevent spring 140 by this hook portion 129 with separate.
In addition, because the basic transverse center portion (between this is to leg section 141) of the press section 127 preferred extrusion springs 140 of unlocking arm 125, so the power that is used for extrusion spring 140 with well balanced mode effect, and can be carried out unlocking operation effectively.
As mentioned above,, separate lock section 131 by pushing according to the foregoing description, spring 140 from insertion position IP towards or to retracted position RP dislocation, with the cancellation lock-out state.Because spring 140 does not need to utilize the finger tip direct control, so operability is good.
Therefore, in order to provide a kind of being used for a pair of member to be locked in the latch-up structure of state of correct connection and the electrical connector in a kind of plan fixes on correct connection by springlock the state by spring, this latch-up structure and electrical connector can easily be carried out the operation of lock-related, a member 110 comprises unlocking arm 125, and this unlocking arm 125 is along extending with the closure of another member 150 and preferably can tilting as seesaw.One end of this unlocking arm 125 is as press section 127, this press section 127 is arranged between spring 140 and the member 110 with along the direction extrusion spring 140 away from this member 110, and the other end of this unlocking arm 125 is used for pushing this press section 127 as separating lock section 131 when being pressed.
Next, the latch-up structure of another embodiment of the present invention is described to Figure 21 with reference to Figure 16.

One or more guiding ribs 242 are preferred be form along the lower surface of main body 241 from the laterally projecting thin plate of the side surface of main body 241 substantially, and preferred from main body 241 trailing edge (or near trailing edge) towards or extend to forward position.Guiding rib 242 will be inserted in the outer tube part 213 and the gap between the guide part 219 of cloudy housing 210 at least in part, and/or can along forward and direction backward slide, preferably can prevent the lifting of limited slip block 240 thus from cloudy housing 210.
Each guiding rib 242 is provided with the protuberance 244 that can engage with engagement windows 221.Protuberance 244 along forward and direction backward in the centre position (preferably in basic center) of guiding rib 242 upwards or outwards outstanding.Protuberance 244 be configured as can be assembled at least in part in the engagement windows 221 and/or can be substantially along forward and direction backward in engagement windows 221, slide, and the front surface of protuberance 244 is preferably formed inclined surface, this inclined surface tilts with side-prominent towards the back more gradually, and the rear surface of protuberance 244 is preferably formed limiting surface 244A, and this limiting surface 244A will engage in case limited slip block 240 separates backward with engagement windows 221 (preferred trailing edge).Protuberance 244 is arranged near the rear end of the joint fastener 245 that (preferred basic for cantilever shape) extend back substantially along the lateral margin of guiding rib 242 or its.Slide block 240 will make joint fastener 245 downward or inwardly (towards the effusion recess 222 of cloudy housing 210) distortion simultaneously from assembling side, preferably being assembled into or being assembled in or being assembled into cloudy housing 210 substantially from behind.
On the side surface of two guiding ribs 242, basic along forward and one or more recoils prevention rib 246 contiguous joint fasteners 245 of extending of direction backward (before joint fastener 245 and/or afterwards) be provided with.The preferably recoil of preventing between limited slip block 240 and the cloudy housing 210 by the recoil prevention rib 223 of one or more recoil prevention ribs 246 and/or outer tube part 213.
When slide block 240 is preferably placed at it slidably during the rearmost position in the scope, the compressive surface 247 of slide block 240 is positioned at such position so that the position of extrusion spring 230 not substantially, and cloudy housing 210 be in can with such state of positive housing 250 lockings in (referring to Figure 22).This moment, the position of slide block 240 was called the lockable position.When slide block 240 is preferably placed at it slidably during the front position in the scope, compressive surface 247 extrusion springs 230 of slide block 240 with towards or to retracted position RP dislocation spring 230, i.e. the lock-out state (referring to Figure 31) of cancellation and positive housing 250.This moment, the position of slide block 240 was called unlocked position.When slide block 240 is in the unlocked position, protuberance 244 is preferably placed at the rear end of engagement windows 221, and engage (referring to Figure 29) with composition surface 255A, and when slide block 240 was in the unlocked position, protuberance 244 was preferably placed at the front end place (referring to Figure 30) of engagement windows 221.Because engagement windows 221 vertically passes,, can (for example, by eyes or external detection device, such as camera) confirm that slide block 240 is in the lockable position or is in the unlocked position so preferably can see the position of protuberance 244.
Next, the operation that male connector M and female connector F are locked in the state that is connected that is in the main true is described.Spring 230 is arranged on insertion position IP usually, and slide block 240 is arranged on the lockable position usually.
At first, operation (for example, using finger grip) cloudy housing 210, and when the passage 225 with respect to 255 pairs of cloudy housings 210 of joint protuberance of positive housing 250 positions, gradually cloudy housing 210 is pushed or dislocation is gone among the male connector M.Then, engage protuberance 255 and in passage 225, move forward, and the front surface that engages protuberance 255 basically forms with the junction surface 233 of spring 230 and contacts.Further move forward along with engaging protuberance 255, the junction surface 233 of spring 230 moves to and engages on the protuberance 255, and leg section 231 edge direction elasticity dislocations away from each other.At this moment, because the contact site 248 of slide block 240 is positioned at spring 230 tops at least in part, so when the elasticity dislocation of leg section 231, can prevent the lifting of spring 230.
When two connector F, M arrive the state of correct connection, the jag that engages protuberance 255 is towards the preceding spring 230 that passes through, leg section 231 to small part elastic return and junction surface 233 and composition surface 255A basic along forward and direction backward face with each other, the result locks two housings 210,250 inseparably.Under the correct situation about connecting of two connector F, M, the inner space of two housings 210,250 is preferably sealed with elasticity or rubber stopper 229 by sealing ring 216 and/or electric wire, and sun and female terminal 211,254 correctly are electrically connected.
Next, how to describe and will be maybe can divide and open being locked in two connector F, M in the state of correct connection.At first, will maybe finger tip can be placed on the contact site 248 of the slide block 240 that is in the lockable position, with to front slide or operation or dislocation slide block 240.Then, compressive surface 247 forms sliding contact with downward or inside extrusion spring 230 with the upper lateral part 232 of spring 230, and the leading section of slide block 240 inserts (promptly inserting among the patchhole 228A) at least in part under promoting prevention portion 227.When spring 230 pushed downwards or inwardly by compressive surface 247, junction surface 233 was preferred substantially along outer guiding that be tilted to of the lower surface 226B of interconnecting part 226, and leg section 231 strain (referring to Figure 32) away from each other.When slide block 240 arrived unlocked positions, junction surface 233 was positioned near the place, bottom of lower surface 226B of interconnecting part 226 or its, and withdrawal from passage 225 substantially, and engaging protuberance 255 thus can move backward, and state promptly unlocks.At this moment, the contact site 248 of slide block 240 forms with the outer wall 251 of device substantially and contacts (referring to Figure 31).Then, when slide block 240 is pressed against on the outer wall 251 of device,, separate two connector F, M thus with maybe finger being placed on the finger placement section 217 of cloudy housing 210 to pull back cloudy housing 210.
By sliding by this way or operation slide block 240, compressive surface 247 and spring 230 basically form sliding contact with towards or to retracted position RP extrusion spring 230, state thus unlocks.Because spring 230 does not need for example by the finger tip direct control, so operability is good.In addition, as in this embodiment, even become in the situation that obstacle and spring 230 can not (for example use finger tip) and directly depress at the outer wall 251 of device, the state that also can unlock, and do not have any problem.Wait the situation of carrying out unlocking operation to compare with using anchor clamps, can save required work of this operation and time, make overall maneuverability improve.
Because spring 230 does not need to utilize directly dislocation of finger tip, so the operability of unlocking operation is good, and lock-out state can do not need to work and the situation of time under remove, irrelevant with the shape of mating component.As a result, make unlocking operation become easier.
In addition, if slide block 240 slides after the lock out operation of two connector F, M is finished or is displaced to the lockable position, be used for then down that the power of pressing spring 230 is released, and junction surface 233 is pressed against on the upper surface 226B of interconnecting part 226 by the elastic restoring force of leg section 231.Then, junction surface 233 is by the inclination of the lower surface 226B of interconnecting part 226 in the basic introduction channel 225, therefore, spring 230 from retracted position RP towards or to insertion position IP dislocation.Therefore, spring 230 preferably only is set to insertion position IP by making slide block 240 turn back to initial position IP (lockable position) automatically, therefore, at two connector F, when the M after separating reconnects them, do not need spring 230 is reset to insertion position IP, and can save required time of connector lock operation and work.
Because the contact site 248 of slide block 240 is at least partially disposed on the top or the outside of the outer or upper lateral part 232 of spring 230, so can prevent upwards (away from the direction of cloudy housing 210) dislocation of spring 230 by contact site 248.Therefore, can prevent the dislocation and the recoil of spring 230 when connecting two connector F, M, and electrical connector can bear the use under the height vibration.
Because the basic transverse center portion (between leg section 231) of slide block 240 preferred extrusion springs 230, so the power that is used for extrusion spring 230 with well balanced mode effect, and can be carried out unlocking operation effectively.
In addition, because preferably being provided with, cloudy housing 210 promotes prevention portion 227, so can prevent the lifting of the leading section of slide block 240 during slide.Therefore, needn't push slide block 240 and make slide block 240 will be not can not promote when extrusion spring 230 downwards, the result can easily carry out unlocking operation.
As mentioned above, according to first embodiment, when slide block 240 slides or during dislocation, the preferred and spring 230 of compressive surface 247 basically forms sliding contact so that spring 230 is pressed to retracted position RP, and state thus unlocks.Therefore, spring 230 does not need to utilize the finger tip direct control, so operability is good and can easily carry out unlocking operation.
Therefore, in order to provide a kind of being used for a pair of member to be locked in the latch-up structure of state of correct connection and the electrical connector in a kind of plan fixes on correct connection by springlock the state by spring, this latch-up structure and electrical connector can easily be carried out the operation of lock-related, when being in insertion position IP, spring 230 with another member 250 (for example positive housing 250) but one or more junction surfaces 255 engage realizing lock-out state, and by be displaced to the retracted position RP state that unlocks from insertion position IP.Can be along being assembled into or being assembled in or be assembled into a member 210 with the closure slip of another member 250 or the slide block 240 (as preferred movable member) of dislocation, and be formed with at least one compressive surface 247, this compressive surface 247 tilt with when by slide during with spring 230 formation sliding contacts can towards or push (or dislocation or act on) spring 230 to retracted position RP.
Next, to Figure 36 according to another embodiment of the present invention latch-up structure is described with reference to Figure 33.
The latch-up structure of this embodiment is different with previous embodiment, is that spring 230 arrives punctured position RP by making progress (away from the direction of cloudy housing 210) dislocation substantially from insertion position IP.By identifying, no longer be repeated in this description or identical construction similar to first embodiment with identical Reference numeral.
Similar to previous embodiment, employing is designed to lock described female connector F and male connector M inseparably by at least one spring 230 that comprises the displaceable leg section 231 of a pair of elasticity according to pair of connectors F, the M (female connector F, male connector M) of the latch-up structure of this embodiment.
Similar to previous embodiment, can be along forward and direction backward (preferably corresponding essentially to the closure with positive housing 250) is slided or the slide block 290 of dislocation is assembled into or is assembled in or be assembled into cloudy housing 210, wherein slidably or the rearmost position in the moving range be the lockable position, and front position wherein is a unlocked position.
The main body 241 of slide block 290 is formed with at least one compressive surface 291, be used for according to moving or slide, interact in (preferably basically forming sliding contact) spring 230 go up outside portion 232 is gone up with upwards or outside extruding or outside portion 232 (towards or to retracted position RP extrusion spring 230).Compressive surface 291 is formed in the part of main body 241 before one or more guiding ribs 242, and towards front end (towards the direction of guiding rib 242) inclination (referring to Figure 34) downwards.
Similar to previous embodiment, contact site 248 is outstanding at the front end place of main body 241.When slide block 290 was in the lockable position, contact site 248 was positioned at upper lateral part 232 tops (referring to Figure 33) of spring 230, and when slide block 290 was in the unlocked position, contact site 248 was outstanding forward from promoting prevention portion 227 (front ends of cloudy housing 210).Similar to previous embodiment, after spring 230 was extruded to retracted position, this contact site 248 formed with the outer wall 251 of positive housing 250 substantially and contacts.
Operation and previous embodiment that male connector M and female connector F are locked in the correct state that is connected are similarly carried out.The operation that two connector F, M that are locked in the state of correct connection are separated is carried out by the slip similar to previous embodiment or operation or dislocation slide block 290, and execution specific as follows.
To maybe finger tip can be placed on the finger contact site 243 of the slide block 290 that is in the lockable position with to front slide or move or dislocation slide block 290.Then, compressive surface 291 engage with the upper lateral part 232 of spring 230 or interact (preferably basically forming sliding contact) with upwards or outwards extruding or dislocation spring 230, junction surface 233 is preferably by along the basic outwards guiding of the inclination of the upper surface 226A of interconnecting part 226, therefore, leg section 231 strain away from each other.When slide block 290 arrived unlocked positions, junction surface 233 was positioned near the upper end of upper surface 226A of interconnecting part 226 or its, and/or withdrawal from passage 225 substantially, and state thus unlocks.At this moment, similar to previous embodiment, because the contact site 248 of slide block 290 forms with the outer wall 251 of male connector M substantially and contacts, so when slide block 290 maybe can be compressed against on the outer wall 251, finger is placed on the finger placement section 217 of cloudy housing 210 to pull back cloudy housing 210, separate two connector F, M thus.
Similar to previous embodiment, because by this way by sliding slider 290 state that unlocks, so can easily carry out unlocking operation.

The rearward end of unlocking arm 327 (other end) is used for pushing this press section 329 as separating lock section 335 when being pressed.The width of separating lock section 335 is preferably wideer than the part before connecting rotating shaft 328 of unlocking arm 327, and is formed in the upper surface of separating lock section 335 towards the acclivitous gradually inclined-plane 336 of pushing of rear side.The lower surface of separating lock section 335 preferably is inclined upwardly towards the rear end, in other words, separates lock section 335 and is configured as and vertically reduces its thickness towards the rear end.The inclination by separating lock section 335 lower surfaces and the back recess 319 of cloudy housing 310 guarantee to separate enough downward elasticity dislocations of lock section 335, have farthest suppressed the height of cloudy housing 310 simultaneously.
When unlocking arm 327 in the raw the time, spring 340 preferably is maintained at insertion position IP, and cloudy housing 310 be in can with the state of cloudy housing 350 lockings.This moment, the state of unlocking arm 327 was called lockable state (referring to Figure 33).Separate lock section 335 so that unlocking arm 327 when tilting when pushing, press section 329 is extrusion spring 340 upwards or outwards, and spring 340 towards or to retracted position RP dislocation, promptly the lock-out state with positive housing 350 is disengaged.This state of unlocking arm 327 is called released state (referring to Figure 42).
Next, the operation that male connector M and female connector F are locked in the correct state that is connected is described.Unlocking arm 327 is arranged on the lockable state usually, and/or spring 340 is arranged on insertion position IP usually.
At first, with the cloudy housing 310 of finger grip, and when the one or more passages 325 with respect to one or more 355 pairs of cloudy housings 310 of joint protuberance separately of positive housing 350 position, cloudy housing 310 is pushed among the male connector M gradually.Then, engage protuberance 355 and in passage 325, move forward, and the front surface that engages protuberance 355 basically forms with the junction surface 343 of spring 340 and contacts.Move forward along with engaging protuberance 355, junction surface 343 moves to and engages on the protuberance 355, and leg section 341 preferred basic edge direction elasticity dislocations away from each other.At this moment, because the protuberance 332 of unlocking arm 327 is positioned at spring 340 tops or the outside at least in part, so when the elasticity dislocation of leg section 341, can prevent that spring 340 from upwards or outwards promoting.
When two connector F, M arrived the correct state that connects, leg section 341 returned elastically, and junction surface 343 with engage protuberance 355 joints, so that two housings 310,350 are locked to each other together inseparably.In the state of the correct connection of two connector F, M, the inner space of two housings 310,350 preferably by sealing ring 316 and one or more electric wire with elasticity or rubber stopper 337 sealings, and sun and female terminal 311,351 correctly be electrically connected.
In two connector F, M of correct connection by this way, spring is kept at least in part or is arranged between protuberance 332 and the press section 329, has therefore prevented the vertical and circumferential dislocation of spring 340 with respect to installation portion 324.Because the joint protuberance 355 of spring 340 and positive housing 350 preferably keeps engaging reliably by the dislocation that prevents spring 340, so can improve the locking reliability.
In addition, because spring 340 is substantially closely remained between limiting surface 334 and the press section 329, so preferably prevented its vibration, and/or owing to spring 340 is preferably substantially closely remained between the first location wall 321 and the second location wall 322, so prevented spring 340 dislocation and the recoil of (longitudinal direction of cloudy housing 310) in the forward and backward directions.Owing to can prevent the relative dislocation of spring 340 and cloudy housing 310 by this way, so two connector F, M can bear the use in high vibration environment.
Next, how to describe and will be maybe can divide and open being locked in two connector F, M in the state of correct connection.At first, for example finger tip is placed on the inclined-plane pushed 336 of the unlocking arm 327 that is in the lockable state, separate lock section 335 downwards to push.Then, unlocking arm 327 tilts, and press section 329 outwards or upwards pushes or dislocation spring 340.At this moment, the protuberance 332 that upwards (away from the direction of cloudy housing 310) dislocation of spring 340 is positioned near (preferably substantially in transverse center portion or it) in the horizontal pars intermedia of spring 340 (preferred basic at this to the centre position between the leg section 341) stops, therefore can prevent that spring 340 from making such dislocation, a side (if protuberance for example is arranged in the position of a cross side of more close spring, then being opposite side) that is spring 340 upwards promotes from press section 329.
When spring 340 by press section 329 upwards or outwards when extruding or dislocation, junction surface 343 is preferred substantially along outer guiding that be tilted to of the upper surface 326A of interconnecting part 326, and/or leg section 341 strain away from each other.When unlocking arm 327 arrived released state, junction surface 343 was positioned at the upper end of the upper surface 326A of interconnecting part 326, with withdrawal from passage 325.Here, unless protuberance 332 is at least partially disposed on the top or the outside of spring 340, otherwise spring 340 may since upwards draw spring 340 too powerful power and with crimping section from.Yet,, can prevent this separation of spring 340 by protuberance 332 is set as in this embodiment.
Because press section 329 preferably changes towards the lateral deviation that spring 340 when the extrusion spring 340 is pressed towards, so can avoid the separating of spring 340 and press section 329 during unlocking operation.
In addition, because the basic transverse center portion of the press section 329 preferred extrusion springs 340 of unlocking arm 327 acts on spring 340 so be used for the power of extrusion spring 340 in well balanced mode, and can carry out unlocking operation effectively.
, when promptly unlocking state, finger is placed on the finger placement section 317 of cloudy housing 310 so that engage protuberance 355 and move backward when operation unlocking arm 327, and hold cloudy housing 310 and pull back, separate two connector F, M thus from basic opposite side.
If after the lock out operation of two connector F, M is finished, pushing the finger of separating lock section 335 moves apart, then unlocking arm 327 returns elastically the lockable state is used for downward or inside extrusion spring 340 with release power to small part naturally, junction surface 343 is pressed against on the upper surface 326A of interconnecting part 326 by the elastic restoring force of leg section 341, and/or inclination by upper surface 326A imports in the passage 325, and therefore, spring 340 from retracted position RP towards or to insertion position IP dislocation.Therefore, spring 340 is preferably only separated lock section 335 and is set to insertion position IP automatically by finger tip is moved apart.Therefore,, do not need spring 340 is reset to insertion position IP, and can save and be used to connect time and the work required with lock connector F, M at two connector F, when the M after separating reconnects them.Therefore, improved overall maneuverability.
When female connector F was stayed separately, the dislocation of spring 340 can stop by protuberance 332 is set.Here, if when female connector F is stayed separately spring 340 dislocations, then when female connector F is linked to each other with male connector M, must again spring 340 be set to correct position, this need work and the time.Yet, by protuberance 332 is set, can prevent the dislocation of spring 340 as in this embodiment, therefore do not need to reset spring 340, can save required time of connector attended operation and work.Therefore, improved overall maneuverability.
Therefore, for a kind of latch-up structure and a kind of electrical connector are provided, this latch-up structure and electrical connector can prevent spring and housing or with respect to the separating of housing, recoil or dislocation, a member 310 comprises unlocking arm 327, and this unlocking arm 327 preferably can tilt as seesaw.One end of unlocking arm 327 is as press section 329, this press section 329 is arranged between spring 340 and the member 310, be used for along direction extrusion spring 340, and the other end of unlocking arm 327 is used for pushing this press section 329 as separating lock section 335 when being pressed away from this member 310.Unlocking arm 327 also comprises protuberance 332 on a side of the spring 340 relative with press section 329.
