Description

  The present invention relates to a connector in which terminals are conductively connected by connecting to a connected portion such as a receptacle.

  In a joint connector having a joint circuit and a mating connection terminal connected to the ends of a plurality of electric wires connectable to the joint circuit, the connection terminal is slit at the tip side by pressing a metal plate. Is formed, and the connection terminal portion of the joint circuit is inserted into the slit of the connection terminal (see, for example, Patent Document 1).

JP 2007-287418 A

  By the way, in the above connector, since the slits are formed on both side portions of the box portion that accommodates the pressure contact pieces that are the contact points that are in pressure contact with the joint circuit, the rigidity at the distal end portion of the connection terminal is reduced. There was a risk of deformation due to external forces.

  In addition, since the slits are formed on both side portions of the box portion, the pressure contact pieces that become the contact points in the box portion are exposed more. For this reason, when the connection terminal is transported, attached to the housing, or when the electric wire is crimped, the pressure contact piece may be damaged or deformed, resulting in poor conduction.

  Further, the connection terminal is locked by a lance formed in the housing and is prevented from coming off. This lance is elastically deformed when the connection terminal is inserted into the housing, and the locking hole of the connection terminal is formed in the lance. It is inserted to the position beyond the claw and restored to lock the connection terminal. When locking the connection terminal with such a lance, a clearance is provided between the claw portion of the lance and the locking hole so that the lance is reliably restored and locked to the connection terminal. It is necessary to insert the connection terminal slightly behind the place where the connection terminal is engaged with the engagement hole.

  Therefore, in the case of such a structure, even if the claw portion of the lance enters the locking hole of the connection terminal, the connection terminal is displaced along the insertion direction by the clearance.

  As described above, when the connector is used in the structure in which the connection terminal is displaced, when the connector is used for wiring of a vehicle such as an automobile, the connection terminal is displaced by vibration generated when the vehicle travels, and the connection between the joint circuit and the pressure contact piece. There is a risk of causing an increase in electrical resistance or occurrence of poor conduction due to contact wear at the contact point.

  The present invention has been made in view of the above-described circumstances, and its purpose is connection reliability that enables good conductive connection without defects such as deformation and damage due to external interference and contact wear due to vibration. It is to provide a high connector.

Is the connection between the board and the connection terminal Perspective view showing a cross-sectional view of a connector connected to the FIG. 13 receptacle.

  As shown in FIGS. 1 and 2, the connector 11 according to the first embodiment is connected to a receptacle 12 that is a connected portion. The connector 11 includes a housing 31 and a plurality of connection terminals 41 attached to the housing 31, and the connection terminals 41 are connected to the end of the electric wire 1.

  The receptacle 12 is formed from a synthetic resin, and is formed in a box shape in which the connection side of the connector 11 is an opening 21. The opposite side of the receptacle 12 from the opening 21 is provided with a wall portion 22 and is closed. The wall portion 22 is provided with a plate-like substrate portion 24 extending to the opening 21 side. . A printed circuit 24a is formed on the front and back surfaces of the substrate portion 24, and a contact made of a part of the printed circuit 24a is provided on the lower surface.

  As shown in FIG. 3, a plurality of substrate slits 25 respectively corresponding to the connection terminals 41 of the connector 11 are formed in the substrate portion 24 at the end on the opening portion 21 side with an interval in the width direction. .

  As shown in FIG. 4, the connector 11 connected to the receptacle 12 includes a housing 31 and connection terminals 41 accommodated in the housing 31.

  As shown in FIGS. 5 to 7, the housing 31 is formed from a synthetic resin, and a plurality of cavities 32 penetrating in the front-rear direction are formed in parallel at intervals in the width direction. In these cavities 32, connection terminals 41 are inserted and accommodated from terminal insertion ports 32a on the rear end 31a side of the housing 31, respectively.

  A lance 33 is formed on the bottom of the cavity 32 so as to extend from an intermediate portion in the front-rear direction of the housing 31 to the front side of the housing 31. A claw portion 34 protruding to the inside is formed.

  An insertion hole 35 communicating with the cavity 32 is formed at the tip 31 b of the housing 31. Further, a connector slit 39 into which the substrate portion 24 of the receptacle 12 can be inserted is formed at the front end 31 b of the housing 31 in the width direction of the housing 31. The connector slit 39 is formed in the vicinity of the center of the cavity 32 in the height direction so as to communicate with each cavity 32.

  The connection terminal 41 accommodated in the cavity 32 of the housing 31 is obtained by pressing a metal plate formed of copper or a copper alloy, and the surface thereof is subjected to tin plating for improving electrical connection performance. Is preferred.

  As shown in FIG. 8 to FIG. 10, the connection terminal 41 is provided with an electrical connection portion 42 at the tip and a crimping portion 43 at the rear end.

  The crimping portion 43 on the rear end side includes a conductor crimping portion 43a and a covering crimping portion 43b, and the electric wire 1 is crimped and connected to the crimping portion 43.

  Specifically, the conductor exposed from the coating at the end of the electric wire 1 is crimped to the conductor crimping portion 43a, and the coating of the electric wire 1 is crimped to the coating crimping portion 43b.

  The electrical connection part 42 on the distal end side has a box part 45 formed in a rectangular tube shape by bending a metal plate, and a contact spring 48 is accommodated in the box part 45 therein. Yes.

  The contact spring 48 extends from the front end of the bottom plate portion 46 that forms the bottom surface of the box portion 45, and is folded back at the front end of the bottom plate portion 46 and inclined upward toward the rear end. Further, the contact spring 48 has its tip end folded back downward. The contact spring 48 has a contact 49 at its upper end.

  A terminal slit 52 is formed on one side wall 51a of the side walls 51a and 51b constituting the box portion 45 from the front end to the rear end side, and the substrate portion 24 of the receptacle 12 is inserted into the terminal slit 52. It is possible.

  Further, a locking hole 55 is formed in the bottom plate portion 46 constituting the bottom of the box portion 45, and the claw portion 34 of the lance 33 formed in the cavity 32 of the housing 31 is formed in the locking hole 55. It can be locked.

  In the connector 11, in order to accommodate the connection terminal 41 in the housing 31, the connection terminal 41 is inserted into each cavity 32 from the terminal insertion port 32 a on the rear end 31 a side of the housing 31.

  At this time, the contact spring 48 of the connection terminal 41 is in a state of being accommodated in the box portion 45 without being exposed to the outside, so that the contact spring 48 does not contact the wall surface forming the cavity 32. Therefore, deformation and damage of the contact spring 48 due to contact of the contact spring 48 with the wall surface of the cavity 32 and an increase in insertion resistance of the connection terminal 41 into the cavity 32 are prevented, and the connection terminal 41 is inserted into the cavity 32 with a small insertion force. It can be inserted and assembled smoothly.

  When the connection terminal 41 is inserted into the cavity 32, the connection terminal 41 comes into contact with and slides on the claw portion 34 of the lance 33, and the claw portion 34 is pushed down to elastically deform the lance 33. Since the lance 33 is made of resin, it is elastically deformed with a very small external force. Therefore, even if the connection terminal 41 contacts and slides on the claw portion 34 of the lance 33, the insertion resistance of the connection terminal 41 into the cavity 32 hardly increases.

  Then, when the connection terminal 41 is inserted into the cavity 32 to a predetermined position, the elastically deformed lance 33 is restored as shown in FIG. 4, and the engagement hole 55 formed in the bottom plate portion 46 of the connection terminal 41 is restored. The claw portion 34 of the lance 33 enters and is locked, and the connection terminal 41 is accommodated in the cavity 32 in a state in which the connection terminal 41 is prevented from coming out of the cavity 32.

  Next, the case where the connector 11 in which the connection terminal 41 is accommodated in each cavity 32 of the housing 31 is connected to the receptacle 12 will be described.

  In order to connect the connector 11 to the receptacle 12, the distal end side of the connector 11 is inserted into the opening 21 of the receptacle 12.

  Then, as shown in FIG. 11, the board portion 24 of the receptacle 12 enters the connector slit 39 formed in the housing 31 of the connector 11.

  Further, when the connector 11 is inserted into the receptacle 12, as shown in FIG. 12, the substrate portion 24 enters the terminal slit 52 formed in one side wall 51a constituting the box portion 45 of the connection terminal 41, and the connection terminal The other side wall 51 b of the box portion 45 of 41 enters the substrate slit 25 formed in the substrate portion 24.

  As a result, the connector 11 is smoothly guided to the inside of the receptacle 12 by the board portion 24 that has entered the connector slit 39. The board portion 24 is smoothly guided to the connection terminal 41 by entering the terminal slit 52, and the connection terminal 41 is well positioned in the width direction of the board portion 24 by entering the side wall 51 b to the board slit 25. Guided.

  Further, when the connector 11 is inserted into the receptacle 12, the substrate portion 24 is inserted above the contact spring 48 of each connection terminal 41 accommodated in the cavity 32, as shown in FIG. 13.

  Then, the substrate portion 24 comes into contact with the contact 49 of the contact spring 48 and the contact spring 48 is pushed down while being elastically deformed downward, and the contact 49 comes into contact with a contact formed by a part of the printed circuit 24a on the lower surface side of the substrate portion 24. Is conducted.

  As described above, according to the connector according to the first embodiment, the contact spring 48 of the connection terminal 41 is housed in the box portion 45 and protected, so that the contact spring 48 is deformed or damaged due to interference with the outside. , And an increase in insertion resistance due to the contact spring 48 coming into contact with the housing 31 can be prevented. As a result, an increase in electrical resistance and poor conduction due to deformation or damage of the contact spring 48 can be prevented, and the assembly workability by smooth insertion of the connection terminal 41 into the housing 31 can be improved.

  In addition, since the side wall 51 b of the connection terminal 41 is inserted into the substrate slit 25 and the substrate portion 24 is inserted into the terminal slit 52 by connection to the receptacle 12, the connection terminal 41 is relative to the substrate portion 24. Therefore, the contact spring 48 can be surely brought into contact with a predetermined position of the substrate portion 24 to obtain a good conduction state. In addition, compared to the case where a plurality of terminal slits 52 are formed in the connection terminal 41, the rigidity of the connection terminal 41 can be suppressed as much as possible, and deformation due to an external force can be sufficiently prevented, thereby improving the handleability. In addition, the exposure of the contact spring 48 can be suppressed as much as possible and can be sufficiently protected.

  In the above-described embodiment, the connection terminal 41 is used in which the contact point 49 is brought into contact with the lower surface of the substrate part 24 and is electrically connected to the contact point of the printed circuit 24a on the lower surface of the substrate part 24. Alternatively, the contact 49 may be brought into contact with the upper and lower surfaces of the substrate 24 so as to be electrically connected to the contacts of the printed circuit 24 a on the upper and lower surfaces of the substrate portion 24.

  FIG. 14 and FIG. 15 show a connection terminal 41 having a contact 49 that contacts the upper and lower surfaces of the substrate portion 24. In the connection terminal 41, a pair of upper and lower contact springs 48 are accommodated in the box part 45, and the contacts 49 of these contact springs 48 are arranged at positions facing each other. In this connection terminal 41, the upper surface of the box portion 45 is composed of upper plate portions 53a and 53b that extend from the upper edges of the side walls 51a and 51b and overlap each other. The contact spring 48 provided at the upper portion extends from the front end of the lower upper plate portion 53a, is folded back at the front end of the upper plate portion 53, and is inclined downward toward the rear end. Is folded upward.

  When the connector 11 having the connection terminal 41 is inserted into the receptacle 12, the substrate portion 24 is inserted between the upper and lower contact springs 48 of each connection terminal 41 accommodated in the cavity 32 as shown in FIG. Is included.

  Then, the substrate portion 24 comes into contact with the respective contacts 49 of the upper and lower contact springs 48, the upper and lower contact springs 48 are elastically deformed, and the gaps are pushed wide, and the respective contact points 49 are printed on the upper and lower surfaces of the substrate portion 24. Are brought into contact with each other and made conductive.

  As described above, according to the connector including the connection terminals 41 having the contact springs 48 on the upper and lower sides, the contact springs 48 come into contact with both surfaces of the substrate portion 24 when connecting to the receptacle 12, so that the connection terminals 41 are connected to the substrate portion. It is possible to conduct simultaneously to the contacts on both sides of the 24. Further, since the contact springs 48 are brought into contact from both sides of the substrate part 24, the substrate part 24 is sandwiched by the contact springs 48, and the contact springs 48 can be brought into contact with the substrate part 24 without rattling. A good conduction state can be ensured.

(Second Embodiment)
Next, a connector according to the second embodiment will be described.

  Note that the same components as those of the connector according to the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  17 and 18 show the connection terminals 61 used in the connector 11 according to the second embodiment.

  In the connection terminal 61, a biasing portion 62 is formed at the tip of the other side wall 51b inserted into the substrate slit 25 of the substrate portion 24 of the side walls 51a and 51b constituting the box portion 45. The urging portion 62 is formed in a linear shape, and both ends thereof are coupled to the top and bottom at the tip of the side wall 51 b, and the middle portion is curved in an arc shape so as to protrude toward the tip of the connection terminal 61.

  FIG. 19 shows a state in which the connection terminal 61 is accommodated in the cavity 32 of the housing 31.

  Here, the lance 33 of the housing 31 is elastically deformed when the connection terminal 61 is inserted into the housing 31, and is restored when the locking hole 55 of the connection terminal 61 is inserted to a position beyond the claw portion 34 of the lance 33. Then, the connection terminal 61 is locked. When the connection terminal 61 is locked with such a lance 33, in order to reliably restore the lance 33 and lock the connection terminal 61 with the connection terminal 61, as shown in FIG. It is preferable to provide a clearance C between the locking hole 55 and the locking hole 55 of the lance 33 so that the connection terminal 61 is inserted slightly behind the locking position of the claw portion 34 of the lance 33 to the locking hole 55.

  Thus, when the connector 11 having the clearance C between the claw portion 34 of the lance 33 and the locking hole 55 of the connection terminal 61 is inserted into the receptacle 12, as shown in FIG. 25, the other side wall 51b constituting the box portion 45 of the connection terminal 61 is inserted. Then, the urging portion 62 at the tip of the side wall 51 b comes into contact with the bottom portion 25 a of the substrate slit 25.

  As a result, the connecting terminal 61 is displaced by being pushed toward the rear end 31 a with respect to the housing 31, and the front edge of the locking hole 55 comes into contact with the claw 34 of the lance 33 to eliminate the clearance C. The

  Further, when the connector 11 is inserted into the receptacle 12, as shown in FIG. 21, the urging portion 62 is further pressed and elastically deformed by the bottom portion 25a of the substrate slit 25, whereby the connection terminal 61 is connected to the urging portion. The elastic force of 62 urges the rear end 31 a of the housing 31, and the front edge of the locking hole 55 is pressed against the claw 34 of the lance 33.

  As a result, the backlash of the connection terminal 61 due to the clearance C is eliminated. Therefore, even if the connector 11 is used for wiring of a vehicle such as an automobile, the connection terminal 61 is caused by vibration generated when the vehicle travels. It is possible to prevent such a problem that the electrical resistance increases due to contact wear and a poor conduction occurs.

  Also in the case of the connector 11 according to the second embodiment, as shown in FIG. 22, the connection terminal 61 includes a pair of upper and lower contact springs 48, and the contact points 49 of these contact springs 48 are connected to the upper and lower surfaces of the substrate portion 24. It is also possible to use one that is brought into contact with the contact of the printed circuit 24a on the upper and lower surfaces of the substrate portion 24.

  According to the connector 11 including the connection terminal 61 having the contact springs 48 on the upper and lower sides, the connection terminal 61 can be simultaneously conducted to the contact points on both surfaces of the board portion 24, and the contact point with respect to the board portion 24 can be provided. The spring 48 can be brought into contact with no backlash, and a good conduction state can be ensured.

  Further, since the substrate portion 24 is sandwiched between the upper and lower contact springs 48, even if the urging force of the urging portion 62 is lowered, it is possible to satisfactorily prevent the connection terminal 61 from rattling.

  Next, a modification of the connector 11 according to the second embodiment will be described.

  What is shown in FIG. 23 is a connection terminal 71 used in a modification of the connector 11 according to the second embodiment.

  This connection terminal 71 also has a biasing portion 72 formed at the tip of the other side wall 51b inserted into the substrate slit 25 of the substrate portion 24 of the side walls 51a, 51b constituting the box portion 45. The urging portion 72 is formed in a linear shape, one end of which is connected to the upper portion at the tip of the side wall 51b, the connecting portion is curved, and the other end extends downward.

  Even when the connection terminal 71 is accommodated in the cavity 32 of the housing 31, a clearance C is formed between the claw portion 34 of the lance 33 and the locking hole 55 as shown in FIG.

  When the connector 11 having the connection terminal 71 is inserted into the receptacle 12 and connected, the urging portion 72 is pressed and elastically deformed by the bottom 25a of the substrate slit 25 as shown in FIG. 71 is urged toward the rear end 31 a of the housing 31 by the elastic force of the urging portion 72, and the front edge portion of the locking hole 55 is pressed against the claw portion 34 of the lance 33.

  As a result, the backlash of the connection terminal 71 due to the clearance C is eliminated, and therefore, even if the connector 11 is used for wiring of a vehicle such as an automobile, the connection terminal 71 is caused by vibration generated when the vehicle travels. It is possible to prevent such a problem that the electrical resistance increases due to contact wear and a poor conduction occurs.

  Also, in the case of the modification of the connector 11 according to the second embodiment, as shown in FIG. 26, the connection terminal 71 includes a pair of upper and lower contact springs 48, and each contact 49 of these contact springs 48 is connected to the substrate. It is also possible to use one that is brought into contact with the upper and lower surfaces of the portion 24 to be brought into contact with the contact of the printed circuit 24a on the upper and lower surfaces of the substrate portion 24.

  According to the connector 11 including the connection terminal 71 having the contact springs 48 on the upper and lower sides, the connection terminal 71 can be simultaneously conducted to the contacts on both surfaces of the substrate portion 24, and the contact point with respect to the substrate portion 24 is also provided. The spring 48 can be brought into contact with no backlash, and a good conduction state can be ensured.

  Moreover, since the board | substrate part 24 is clamped by the upper and lower contact spring 48, even if the urging | biasing force of the urging | biasing part 72 is made low, the play of the connection terminal 71 can be prevented favorably.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
