[Industrial Applications]

The present invention relates to a coupling detecting device for a connector for detecting whether or not a connector used for connection of an automobile wiring or the like is properly coupled.

[0003]

In a connector used in a wiring system such as an airbag of an automobile, it is necessary to specifically check whether or not the connector is fully engaged.

Conventionally, there is known a connector having a coupling detection function as disclosed in Japanese Patent Application Laid-Open No. 3-285280. 26, 27 and 28 are structural diagrams of the connector described in this publication.

In the drawing, reference numeral 1 denotes a female connector, and 2 denotes a male connector to be coupled thereto.

A lock chamber 3 is formed on the outer surface of the female connector 1. The outer surface of the male connector 2 is provided with a flexible member 3 that enters the lock chamber 3 when the both connectors 1, A flexible locking arm 4 is provided.

Locking protrusions 5 and 6 are provided at the front end of the lock arm 4 and at the front end of the lock chamber 3 to lock each other when both the connectors 1 and 2 are in a fully engaged state.

Reference numeral 7 denotes a slider, and the slider is freely mounted along the lock arm 4. The slider 7 is provided with a stopper 9 for extending the lock detecting arm 8 at the front and engaging with the lock projection 5 of the lock arm 4 at the front end thereof, And a guide (10). On the lower surface of the lock detecting arm 8, there is provided a protrusion 12 which engages with the protrusion 11 on the outer surface of the male connector 2. [ 27, the female connector 1 and the male connector 2 each contain a male terminal 21 and a female terminal 23 connected to the front end of the wire 22, respectively.

When this connector is used, the slider 7 is mounted as shown in FIG. 27 in advance. That is, the slider 7 enters the passage along the lock arm 4, and the stopper 9 of the lock detecting arm 8 is fitted to the lock projection 5 of the lock arm 4. The support guide 10 supports the locking protrusion 5 from below and the protrusion 12 on the lower surface of the slider 7 is caught over the protrusion 11 on the outer surface of the male connector 2. [

From this state, the female type connector 1 and the slider 7 hooked to the male type connector 2 are advanced in the engaging direction. Then, the tip of the lock arm 4 slides on the guide surface of the lock projection 6 on the side of the female connector 1, and advances while bending downward. At this time, since the stopper 9 of the lock detecting arm 8 and the support guide 10 are engaged with the lock projection 5 of the lock arm 4 of the slider 7, the lock detecting arm 8 The stopper 9 is also shifted to the lower side of the lock projection 6 on the side of the female connector 1. [

29 (a), when the lock projection 5 of the lock arm 4 moves further inward than the lock projection 6 on the female connector 1 side, The locking arm 4 is elastically restored and turned upside down so that the locking projection 5 of the locking arm 4 engages with the locking projection 6 of the female connector 1 side. As a result, the male and female connectors 1 and 2 are completely fitted and locked at the same time, and the electrical connection between the male terminal 21 and the female terminal 23 is achieved. At this time, the lock projection 6 on the side of the female connector 1 presses the stopper 9 from above, and further, the lock projection 5 of the lock arm 4, which is an obstacle, is not present in front of the stopper 9 The slider 7 can be advanced.

When the slider 7 is pushed, the lock detecting arm 8 advances and the stopper 9 reaches the inside of the lock projection 5 of the lock arm 4. As shown in FIG. 29 (c) As a result, the lock detecting arm 8 resiliently returns, thereby moving the slider 7 to the lock confirming position.

As described above, the slider 7 is moved for the first time when both the connectors 1 and 2 are engaged and locked and the engagement between the lock arm 4 and the lock detecting arm 8 is released .

Until then, it does not move. Therefore, the detection of whether or not the connector is fully engaged can be reliably confirmed by the operating state of the slider 7. [

Next, another conventional example will be described.

In the conventional example described above, mechanical engagement detection is performed according to the operating state of the slider. However, the conventional example described next is such that it can be electrically coupled with the operating state of the slider.

As a conventional example of this type, there is known one disclosed in Japanese Patent Application Laid-Open No. 3-32377.

30 and 31 show the structure of the connector described in this publication. The connector includes a female connector housing 30 which is coupled to be opposed to each other, a slider 50 to which a male connector housing 40 and a female connector housing 30 are movably mounted to the rear of the female connector housing 30, A shorting spring 56 which is mounted on the slider 50 and shorts between a pair of male terminals 21 in the female connector housing 30 and a rear holder 60. The spring 55 is provided with a spring 55,

Male terminals 21 and female terminals 23 joined to the front end of the electric wire 22 are received and engaged in the female connector housing 30 and the male connector housing 40, respectively.

The male connector housing 40 has a cantilevered locking arm 44 formed with two locking projections 42 and 43 and the front locking protrusion 43 is engaged with the female connector housing 30 And the engaging protrusion 42 on the rear side is engaged with the slider 50. As shown in Fig.

The shorting spring 56 has a pair of openable and closable elastic arms 56a and 56a and the ends of the elastic arms 56a and 56a are brought into contact with the two male terminals 21 and 21, (21, 21) are short-circuited.

The slider 50 has a locking plate 52 extending forward from the main body portion 51 and has a locking hole 53 at the front end of the locking plate 52. The slider 50 is inserted into the slider housing chamber 31 of the female connector housing 30 and the engagement protrusion 34 of the tip of the temporary lock arm 33 provided on the female connector housing 30 is engaged with the lock plate 52 by engagement with the retaining hole 53 of the retaining ring 52. As shown in Fig. The slider 50 is pushed rearward by the spring 55 interposed between the collision wall 32 of the slider housing chamber 31 and the main body portion 51. [

In the interior of the female connector housing 30, there is provided an engaging portion 35 to which the engagement protrusion 43 on the front side of the male connector housing 40 is engaged. As shown in FIGS. 32 (b) and 33 (b), elastic arms 56a, 56b of the shorting spring 56 moving as the slider 50 are provided in the female connector housing 30, An insulating wall 37 for guiding the elastic arms 56a and 56a away from the terminals 21 is provided by slidably joining the elastic arms 56a and 56a.

When this connector is used, the slider 50 is mounted in advance in the female connector 30 as shown in FIGS. 32 (a) and 32 (b). That is, the engagement hole 53 of the lock plate 52 of the slider 50 is engaged with the engagement projection 34 of the temporary lock arm 33. In this state, the shorting spring 56 short-circuits the pair of terminals 21, 21. Next, as shown in Figs. 33 (a) and 33 (b), the male connector housing 40 is engaged with the female connector housing 30. The engaging projection 43 on the front side of the present locking arm 44 of the male connector housing 40 engages with the engaging portion 35 of the female connector housing 30 in the fully engaged state.

In this state, the slider 50 is advanced. The engaging hole 53 at the front end of the lock plate 52 of the slider 50 engages with the engagement protrusion 42 on the rear side of the lock arm 41. In this state, Lt; / RTI &gt; In this case, the latching hole 53 of the slider 50 does not engage with the lock projection 42 of the lock arm 41 but is returned to the original position by the force of the spring 55, unless the locking projection 42 is in the correct position. Further, even when the slider 50 is pushed into the middle position, the slider 50 returns to its original position shown in FIG. Thus, incomplete coupling and incomplete locking can be confirmed by the slider 950 in the initial position. In addition, when the slider 50 is put in the middle pushing state, the slider 50 is automatically returned by the force of the spring 55, so that the middle pushing can be reliably avoided.

The shorting spring 56 is pushed forward and the elastic arms 56a and 56a are released from the terminal 21 in the state of the main engagement. Therefore, it is possible to confirm the engagement state of the connector by electrically detecting that the short circuit is solved.

[Problems to be solved by the invention]

26-29, there is only one stopper (locking protrusion 5 and stopper 9) for stopping the advancement of the slider 7, The lock detecting arm (the flexible arm 8) is out. Therefore, when an external force is applied and the lock detecting arm is warped, there is a possibility that the engagement state in which the slider 7 can be easily moved can not be detected regardless of the engagement state of the connector.

In addition, although the engagement state of the connector is confirmed by the position of the slider 7, there is a possibility that the slider 7 may be pushed up to the middle and left unchanged depending on the working environment or the like. In such a case, it is impossible to judge from the outside whether or not it is a perfect combination, and there is a problem that the second inspection must be performed again.

30 to 33, since the slider 50 is returned and urged by the spring 55 to the temporary locking position, the effect of preventing the slider 50 from being erroneously pushed in or being pushed in is prevented However, the cost is increased as much as the springs 55 need to be returned unnecessarily.

Since the shorting spring 56 for electrically detecting the engagement state of the connector is mounted on the slider 50 and moved like the slider 50, it is difficult to stably maintain the shorting spring 56, There is a possibility that it is misaligned, and in the case of misalignment, there is a fear that the reliability of the electrical detection is deteriorated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a connection detecting device for a connector which can reliably detect without increasing the number of parts and cost in consideration of the above circumstances.

[MEANS FOR SOLVING THE PROBLEMS]

[Action]

According to the invention of claim 1, since the terminals are short-circuited by the shorting member when the slider is at the temporary locking position and the short circuit is released when the slider is at the main locking position, the incomplete coupling can be electrically detected, The movement of the slider can also be electrically detected. In addition, since the reaction force is received from the shorting member when the slider is moved from the temporary locking position to the locking position, even if the temporary locking is lost for some reason, the insertion of the slider can be prevented and unnecessary movement of the slider is prevented. In addition, when the pushing operation of the slider is stopped in the midway, the slider is returned to the original position because it is not moved to the main hooking position. Furthermore, The short-circuiting member is stably held, and the occurrence of the displacement is reduced.

According to the invention of claim 2, since the pair of breaking arms provided on the slider are guided in the guide groove in the guide groove, the movement of the slider is not stabilized and tilted, and the interposition between the short- .

According to the invention of claim 3, since the blocking arm provided on the slider is guided in the guide groove of the connector housing, the movement of the slider is not stabilized and tilted, and the interposition between the shorting member and the contact portion of the terminal is smoothly performed . Further, as compared with the invention of claim 2, since one blocking arm is inserted between the elastic arm and the terminal, the resistance at that time is reduced.

In the invention of claim 4, there is a feeling of clicking on the operation of the slider by the engaging portion of the blocking arm. Particularly, at the time of complete engagement, the slider is moved to the main engagement position by the urging force of the shorting member. Therefore, the slider is not stopped at a midway position, and a highly reliable detection result is obtained.

According to the invention of claim 5, the slider is reliably stopped at the temporary stop position by the two stoppers. In this case, at least one stopper is located inside the connector housing, and the flexible arm of the slider striking the stopper hides inside the connector housing. Therefore, there is almost no fear that an external force is applied to the flexible arm for some reason.

According to the invention of claim 6, when the slider reaches the main engagement position, the main engagement portion engages with the one connector housing. Therefore, the position of the slider in the engaged state does not move, and the reliability of the engagement detection by the position of the slider is increased.

The slider 300 has the engaging protrusion 342 provided on the front surface side of the first flexible arm 340 and the engaging protrusion 321 provided on the lower surface side of the second flexible arm 32 Even if excessive force is exerted on the first slider stopper 150, the first slider stopper 150 and the second slider stopper 150 are engaged with each other, I am confronted and surely the advance is stopped. Therefore, even if the slider 300 meets any condition, erroneous insertion is prevented.

7, when the female connector housing 200 is coupled to the female connector housing 100, the female connector housing 200 is engaged with the male connector housing 100 The two male connector housings 100 and 200 are completely engaged with each other so that the male and female terminals 21 and 23 are electrically connected to each other on the opposite side over the engaging portion 112 of the flexible lock arm 105 Respectively. As a result, the engaging projection 342 of the first flexible arm 340 of the slider 300, which is first engaged with the engaging portion 210 of the female connector housing 200, is pushed downward , The first flexible arm 340 is bent downward.

The guide projection 208 of the guide projection 208 is moved in the direction of the guide groove 208 of the second flexible arm 320 by the guide projection 208 of the tip of the release operation projection 206 advancing between the second slider stoppers 150. [ And slides on the guide slope 324 at the tip end, so that the second flexible arm 320 is bent upward.

As a result, the engaging protrusion 342 of the first flexible arm 340 is pulled to a position where it does not abut against the engaging portion 112 of the flexible locking arm 105, The second slider stopper 322 is attracted to a position avoiding sticking with the second slider stopper 150. [

Therefore, the slider 300 can advance from the temporary hitching position.

Thus, the slider 300 is advanced. The main locking projection 352 of the slider 300 is engaged with the main locking projection 114 of the flexible locking arm 105 to fix the slider 300. [

At the same time, the tip of the breaking arm 310 of the slider 300 is advanced from the guide plate portion 412 at the tip of the shorting spring 400 by the forward movement of the slider 300, The shorting spring 400 bends the elastic arm 404 inward and separates the contact piece 410 from the terminal 23 so that the terminal 23 is brought into contact with the terminal 23, To release the paragraph. Therefore, it can be confirmed that the slider 300 has reliably reached the engagement position because the short circuit is released.

10 shows the state of electrical connection when the slider 300 is in the temporary latching position and the shorting spring 400 shorts the two terminal wires 501 and 502. FIG. Reference numeral 503 denotes a short detection bulb 503. FIG. 11 shows an electrical connection state when the short circuit is released by advancing the slider 300 to the main locking position. FIG. 12 is a diagram showing a state in which the detector 510 checks the state of a short circuit between the pair of terminal wires 501 and 502 of the connector housing 500.

According to the connector of this embodiment, in addition to being able to electrically detect the incomplete engagement, even if the slider 300 is forgotten to move, it can be electrically detected. Further, when the slider 300 is in the main engagement state, there is no short-circuiting between the terminals 23 and 23. Therefore, it is not necessary to prepare a detection terminal specifically. , The terminal wires 501 and 502 shown in FIG. 12 are not short-circuited when the slider 300 is moved and the connector is fully engaged, so that the terminal wires 501 and 502 can be commonly used for locking detection and for normal signals .

Since the reaction force to return the slider 300 to the temporary locking position is moved by the elastic force of the elastic arm 404 of the shorting spring 400 when the slider 300 is moved to the main locking position, 300) will not move inadvertently. Further, since an operating reaction force is generated, a reliable operation feeling is obtained. In addition, when the movement of the slider 300 is stopped in the middle, the slider 300 is returned to the original position, so that the lack of pushing of the slider 300 can be immediately recognized. Therefore, inadvertent pushing of the slider 300 can be avoided. Particularly, since the reaction force is given to the shorting spring 400, a redundant spring is unnecessary.

Further, the shorting spring 400 The shorting spring 400 is mounted on the side of the male connector housing 100. Therefore, the shorting spring 400 is mounted in a balanced manner and is not easily displaced. Therefore, the movement of the resilient arm 404 is well balanced when it comes into contact with and contact with the terminal.

In the connector of this embodiment, the slider 300 can be reliably stopped at the temporary stop position by the first and second two slider stoppers (the engaging portion 112 and the second slider stopper 150) have. The second slider stopper 150 and the second flexible arm 320 are located inside the male connector housing 100 so that no external force is applied to the second flexible arm 320 and the slider 300 ) Is prevented from being released. Therefore, the slider 300 does not move from the temporary latched position despite the incomplete engagement state. When the connector housings 100 and 200 are fully engaged and the engaging portions 112 and 210 of the locking mechanism are securely locked, the movement of the first flexible arm 340 is released and the slider 300 moves It is possible to simultaneously confirm the complete engagement of the connector and the locking.

Next, a second embodiment of the present invention will be described.

FIGS. 13 and 14 show a slider 300A used in the connector of the second embodiment. FIG.

The second embodiment is different from the above embodiment in that a mountain-shaped engaging portion 312 is provided on the inner surface of the distal end of the blocking arm 310 of the slider 300A. Therefore, the same parts are denoted by the same reference numerals, and a description thereof will be omitted.

Since the engaging portion 312 of the mountain shape is provided on the blocking arm 310 of the slider 300 in the connector of this embodiment, the slider 300A is moved forward from the temporary hanger state of the slider 300A shown in FIG. 15 The front end face of the engaging portion 312 contacts the front end face of the <-type contact piece 410, as shown in FIG. 16. The blocking arm 310 receives a reaction force from the elastic arm 404 by the action of the inclined surfaces of the tab-shaped contact piece 410 and the engaging portion 312 in this case. This reaction force is greater than in the above embodiment. 17, a large resistance in the returning direction acts on the slider 300A in a state where the slider 300A is inserted halfway. When the slider 300A is advanced further from this state, the vertex of the tapered contact piece 410 exceeds the apex of the mountain-shaped engagement portion 312 as shown in Fig. 18, The force (the force for promoting the engagement) that moves the slider 300A in the main engaging direction (the right side in the figure) moves, and the slider 300A is reliably and promptly moved to the main engaging position.

In this embodiment, the engagement portion 312 of the blocking arm 310 causes a clicking feeling on the operation of the slider 300A. Further, at the time of full engagement, the slider 300A is moved to the main engagement position by the urging force of the shorting spring 400, so that the slider 300A is not stopped at a midway position, A detection result is obtained.

Further, since the slider 300A can be surely engaged with the main engagement position, it is easy to check the detection result.

In the above-described embodiment, the first and second flexible arms 320 are provided on the sliders 300 and 300A, and a double-slider stopper for stopping the movement of the slider is provided. The stopper and the flexible arm on either side may be omitted.

Next, a third embodiment of the present invention will be described.

19 and 20 show the slider 300B used in the connector of the third embodiment.

The third embodiment is different from the above embodiment in that a thin cut-off arm 310 is provided only on one side of the main body 302, and the other structure is basically the same as the above embodiment. Therefore, the same parts are denoted by the same reference numerals, and a description thereof will be omitted.

In the connector of this embodiment, when moving from the temporary locking position to the locking position, the slider 300B is interposed between the contact portions of one of the elastic arms 404 and the terminal 23 of the shorting member 400, And one blocking arm 310 for blocking conduction between the contact portions is provided.

When the slider 300B is advanced from the temporary engagement state of the slider 300B shown in FIG. 21, the front end face of the engaging portion 312 comes into contact with the U-shaped contact piece 410 It touches. In this case, the blocking arm 310 receives a reaction force from the elastic arm 404 by the action of the inclined surfaces of the U-shaped contact piece 410 and the engaging portion 312. This reaction force is smaller than that of the second embodiment. That is, in Embodiment 2, since the two blocking arms 310 and 310 on both sides are provided on the main body 302, the reaction force received from the elastic arm 404 is twice as large as in the present embodiment. Therefore, in the case of the present embodiment, the reaction force received from the elastic arm 404 is half of the second embodiment because the blocking arm 310 is provided on only one side.

As shown in FIG. 23, when the slider 300B is further advanced from this state, the apex of the mountain-shaped engaging portion 312 exceeds the vertex of the one-piece contact piece 410, (Force for urging the main hook) to move in the main hooking direction (the rightward direction in the figure) moves, and the slider 300B is moved to the main hook position securely and promptly.

In this state, the blocking arm 310 is sandwiched between the contact portions of the one elastic arm 404 and the terminal 23 to warp one of the elastic arms 404 of the shorting spring 400, 410 are disconnected from the terminal 23 and the terminals 23 are disconnected from each other. Therefore, it can be confirmed that the slider 300B has reliably reached the engagement position due to the release of the short circuit.

24 shows an electrical connection state when the slider 300B is in the temporary locking position and the shorting spring 400 shorts the two terminal wires 501 and 502. FIG. 503 is a short-circuit detecting bulb. 25 shows an electrical connection state when the shorting of the one elastic arm 404 of the shorting spring 400 and the terminal 23 is released by advancing the slider 300B to the main locking position.

According to the present embodiment, the same effect as that of the second embodiment can be obtained. In addition, since one blocking arm 310 is provided only on one side of the main body 302, the operation force of the slider 300B is reduced to half .

Durability is required because the elastic arm 404 is largely displaced when the slider 300B is inserted and withdrawn. However, in this embodiment, since only one elastic arm 404 is displaced, the elastic arm 404 ) Can be improved.

A guide wall 314 shorter than the blocking arm 310 is provided on one side of the main body 302 where the blocking arm 310 is not provided and the guide wall 314 is inserted into the guide groove 134 The movement of the slider 300B in the longitudinal direction can be reliably guided.

[Effects of the Invention]

As described above, according to the invention of Claim 1, in addition to being able to electrically detect an incomplete bond, it is possible to detect it electrically even if it is forgotten to move the slider. Therefore, even if the detection operation is automated, an initial work miss can be easily checked. In addition, since the terminals are not short-circuited when the slider is in the main engagement state, it is not necessary to prepare a terminal for detection specifically. It is possible to check the engagement state of the connector and forget the movement of the slider I can do it.

In addition, when the slider is moved to the main engagement position, since the reaction force is received by the shorting member, a reliable operation feeling is obtained, and inadvertent movement of the slider can be prevented. In addition, even when the slider is stopped in the middle, the slider is returned to its original position, so that the shortage of the slider can be immediately detected.

Therefore, inadvertent pushing of the slider can be avoided. In addition, since a reaction force is applied to the short-circuiting spring detecting whether or not the terminals are short-circuited, it is not necessary to use a spare spring to generate a reaction force, and the cost can be reduced.

Further, Shaped member is mounted on the connector housing side, the holding of the short-circuiting member is stabilized and deviation is less likely to occur. Therefore, when contacting and releasing the contact with the terminal, the movement of the elastic arm is well balanced and the reliability of the electrical detection improves.

According to the invention of claim 2, the slider is stabilized by the guiding action of the pair of breaking arms on the slider side and the guide groove on the connector housing side. Therefore, the stability in the temporary hitching state is increased, and inadvertent wrong operation is eliminated. Further, since the movement of the slider 9 is also stable, interposition between the short-circuit member and the contact portion of the terminal is smoothly performed, and the reliability of electrical detection is improved.

According to the invention of claim 3, the same effect as that of the invention of claim 2 is obtained. In addition, since one blocking arm is sandwiched between the contact part of one terminal arm and the terminal in comparison with the invention of claim 2, The durability of the elastic arm can be improved.

According to the invention of claim 4, since the click of the slider can be given a clicking feeling by the movement of the engaging portion provided on the blocking arm of the slider, the slider does not stop at a halfway position, and the middle pushing can be avoided. Further, the slider can be reliably engaged with the main engagement position, and the detection result can be easily confirmed.

According to the invention of claim 5, since the slider is stopped at the temporary engagement position by the two stoppers, it is possible to reliably keep the slider in an unmovable state at the time of incomplete engagement. In addition, since at least one of the two stoppers for stopping the slider at the temporary locking position is disposed inside the connector housing, the function of the flexible arm of the slider which is brought into contact with the stopper hardly occurs, An external force acts on the flexible arm, and the slider can not be moved from the temporary locking position. Therefore, the engagement state of the connector can be reliably detected, and the reliability of the detection can be enhanced.

According to the invention of claim 6, since the slider is reliably engaged with the one connector housing when the slider reaches the main engagement position, the position of the slider in the main engagement state is not moved and the confirmation of the engagement detection by the position of the slider is easy And the reliability of the index finger increases.
