Description

  The present invention relates to an abutting connector in which a butting terminal which is brought into conduction with a mating terminal by being abutted against the mating terminal is provided in a pair of connector housings to be fitted and connected.

  The abutting connector includes a pair of connector housings to be fitted and connected, and abutting terminals provided in the pair of connector housings.

  37 and 38 show a conventional example of a butting terminal used in a butting connector.

  The abutting terminal 100 shown here is used in the abutting connector disclosed in Patent Document 1 below, and includes a terminal main body 110, an abutting plate portion 120, and a spring portion 130.

  The terminal body 110 is formed by integrally forming a front end cylindrical portion 111 having a substantially rectangular tube shape and a wire crimping portion 112 extending from the rear end of the front end cylindrical portion 111 by press forming a metal plate. The terminal body 110 is inserted into a terminal housing hole of a connector housing (not shown), is prevented from being detached by engagement with a resin lance in the terminal housing hole, and is held in the terminal housing hole.

  The butting plate portion 120 is disposed so as to protrude from the tip of the terminal main body 110 for connection with a mating butting terminal. The abutting plate portion 120 is a portion that makes electrical contact by abutting against the tip of the abutting terminal in the mating connector housing when the connector housings are fitted and connected.

  The spring portion 130 has a corrugated structure in which the abutting plate portion 120 is supported on the terminal body 110 so as to be elastically displaceable by abutting with the abutting abutting terminal. The spring portion 130 is formed integrally with the abutting plate portion 120 by press forming a metal plate.

  The spring part 130 is assembled to the distal end cylinder part 111 so that the abutting plate part 120 protrudes from the distal end of the distal end cylinder part 111.

  In each connector housing of the abutting connector disclosed in Patent Document 1, the abutting terminal 100 mounted in the terminal accommodating hole is fixed to the end of the terminal accommodating hole by the abutting plate portion 120 by locking with a lance. It is positioned at a specified position that protrudes long.

  In the abutting connector disclosed in Patent Document 1, the pair of connector housings are fitted and connected by an operation of abutting each of the front end surfaces with the positions of the respective terminal receiving holes being aligned. Due to the fitting connection of the pair of connector housings, the abutting plate portions 120 of the abutting terminals 100 mounted on the respective connector housings abut against each other, and the opposing abutting terminals 100 are brought into a conductive connection state.

  The axial load acting on the abutting terminals 100 that abut each other is supported by a resin lance that locks the abutting terminals 100 and a housing lock portion that connects the connector housings together.

Japanese National Patent Publication No. 10-504676

  However, in the abutting connector disclosed in Patent Document 1, the axial load acting between the abutting abutting terminals 100 is supported by a resin lance and a housing lock portion connecting the connector housings. .

For this reason, when resin creep occurs in the resin lance or housing lock due to aging of the resin or the like, the contact pressure between the butted terminals 100 and 100 may be reduced.
That is, as shown in FIG. 39, in the case of the conventional abutting terminal 100, when the connectors 150 and 152 are fitted, the contact load of the spring generated in the direction of the arrow W3 in the axial direction is applied to the lance 140 and the housing lock portion. (Not shown) has a structure for receiving directly. As a result, there is a possibility that the lance 140 and the housing lock portion that have continued to receive a force in the direction of the arrow W3 may be deformed in the direction of the arrow W3 that has continued to receive a load due to resin creep.
When resin creep occurs, due to the deformation of the lance 140 and the housing lock portion, the abutting terminal 100 that should be locked and held at the position of the distance W1 from the abutting section is engaged at the position of the distance W2 from the abutting section. It will be held. If the distance between the locking positions is shifted from W1 to W2 in this way, the normal displacement amount cannot be maintained as the displacement amount of the spring portion of the abutting terminal 100, and the set contact load may not be obtained. It was.

  Further, since the abutting terminals 100 attached to the pair of connector housings are brought into an abutting state only by an operation of abutting the pair of connector housings in the axial direction, the abutting terminals 100 are not yet in the stage before the abutting operation. If foreign matter such as an oxide film or dust adheres to the surface of the abutting plate 120, the abutting plate is sandwiched between the abutting plates 120 and 120 with which the foreign matter abuts. There is a possibility that the electrical connectivity between the abutting terminals may be hindered by the interposition of the abutment.

  Furthermore, since the abutting plate portion 120 is exposed on the side surface of the terminal, when the abutting plate portion 120 is pushed from the side by an external force or the like, the spring portion 130 is deformed, and the contact reliability is lowered. In addition, when the abutting plate part 120 protrudes greatly from the tip of the tip tube part 111, the positioning between the terminals at the time of terminal fitting becomes unstable, the terminals do not fit securely, and the connection reliability decreases. There was a fear.

  Therefore, an object of the present invention is to solve the above-described problem, and between the abutting terminals abutted by resin creep such as a lance locking the abutting terminal in the pair of connector housings to be fitted and connected. The contact pressure can be prevented from lowering, and foreign objects are not interposed between the abutting abutting terminals, preventing the connection between the abutting terminals from being hindered. It is another object of the present invention to provide an abutting connector that can be well maintained over a wide range, and that protects a spring portion from an external force and in which terminals are securely fitted to each other.

The above-described object of the present invention is achieved by the following configurations (1) to (4).
(1) A butting terminal equipped with a butting plate portion at the tip which is held in the terminal receiving hole by the lance and is brought into a conductive state by being pressed against the mating terminal of the same shape via the spring portion;
Each of the terminal receiving holes having the lances is provided, and the terminal receiving hole is shifted in a direction orthogonal to the housing central axis, and from the slide start position facing the housing central axis direction at a predetermined separation distance, the housing central axis direction A pair of connector housings that are fitted and connected to each other by sliding the ends of the abutting terminals together by matching the terminal receiving holes by sliding in a direction orthogonal to
A tip that is formed on the abutting terminal and that engages with the abutting abutting terminal when the abutting end of the mating abutting terminal and the tip are slid together to regulate separation in the axial direction with respect to the abutting abutting terminal. A positioning piece;
A butting connector comprising: a protective wall that projects from the terminal body toward the tip positioning piece and covers both sides of the butting plate portion.

(2) The slide start position in the pair of connector housings is a position where the housing central axes of the respective connector housings coincide with each other, and a predetermined angle phase is shifted around the housing central axis,
The abutting connector according to (1), wherein the slide operation is a rotation operation around the housing central axis.

  (3) The slide start position in the pair of connector housings is a position where a housing central axis of each connector housing is shifted in a direction orthogonal to the housing central axis, and the sliding operation is orthogonal to the housing central axis. The abutting connector according to (1) above, wherein the abutting connector is a parallel movement operation in a moving direction.

  (4) The front ends of the pair of connector housings abut against the mating connector housing when the respective connector housings are positioned at the slide start position, and slide on the abutting surface of the mating connector housing during the sliding operation. The abutting connector according to any one of the above (1) to (3), further comprising a terminal protection protrusion that contacts and restricts displacement of the connector housings in the housing central axis direction.

  According to the configuration of (1) above, the pair of connector housings are slid in the direction orthogonal to the housing central axis direction from the slide start position, thereby completing the fitting connection between the connector housings. The abutting connection between the abutting terminals when the mating connection between the connector housings is completed is a sliding operation in which the ends of the abutting terminals slide against each other. A large collision force does not act on. Furthermore, the abutting terminals in the abutted state are separated from each other abutting terminals in the axial direction by engagement by the tip positioning pieces, and an axial load is applied to the lance. Suppress acting.

  Therefore, the occurrence of resin creep on the lances of the connector housings can be suppressed, and the contact pressure between the abutting terminals can be prevented from being lowered by the resin creep of the lances or the like.

Also, when the abutting terminals housed in the respective connector housings abut each other, the ends of the abutting terminals slide against each other, so that the abutting terminal surface of the abutting terminal is in contact with the surface before the abutting operation. It is possible to rub off foreign substances such as attached oxide film and dust. Therefore, foreign matter is not interposed between the abutting butting terminals and the conducting connection between the butting terminals is not hindered.
Accordingly, the connectivity between the abutting terminals can be maintained well over a long period of time.

  Further, the tip positioning piece can smoothly enter between the leading tip positioning piece and the abutting plate portion while being guided by the protective wall. Further, since the protective wall covers both sides of the abutting plate portion, it is possible to prevent the spring portion from being deformed by applying a load to the abutting plate portion during transportation or the like. Furthermore, after completion of the fitting of the butting terminals, the movement of the butting plate portion is restricted by the protective wall, and the contact sliding due to the vibration of the butting connector can be prevented.

  According to the configuration of (2) above, after the pair of connector housings are positioned at the slide start position, the connector housings can be connected and abutted by simply rotating each connector housing about the center axis of the housing. Connection between terminals can be completed. Therefore, the operability when connecting the abutting terminals can be improved.

  According to the configuration of (3) above, after the pair of connector housings are positioned at the slide start position, the connector housings can be connected to each other only by translating each connector housing in a direction perpendicular to the housing central axis. The connection between the butting terminals can be completed. Therefore, the operability when connecting the abutting terminals can be improved.

  According to the configuration of (4) above, when fitting and connecting a pair of connector housings, the distal ends of the connector housings that are abutted by the terminal protection protrusions provided at the distal ends of the respective connector housings The distance between them is maintained. Therefore, by appropriately selecting the protruding length of the terminal protection protrusion, it is possible to avoid an excessive collision force acting on the abutting terminal at the time of abutting. It is possible to prevent deformation.

  According to the abutting connector of the present invention, the abutting connection between the abutting terminals when the fitting connection between the pair of connector housings is completed is a sliding operation in which the ends of the abutting terminals are slid together. A large collision force does not act on each butting terminal in the axial direction. Furthermore, the abutting terminals in the abutted state are separated from each other abutting terminals in the axial direction by engagement by the tip positioning pieces, and an axial load is applied to the lance. Suppress acting.

  Therefore, the occurrence of resin creep on the lances of the connector housings can be suppressed, and the contact pressure between the abutting terminals can be prevented from being lowered by the resin creep of the lances or the like.

Also, when the abutting terminals housed in the respective connector housings abut each other, the ends of the abutting terminals slide against each other, so that the abutting terminal surface of the abutting terminal is in contact with the surface before the abutting operation. It is possible to rub off foreign substances such as attached oxide film and dust. Therefore, foreign matter is not interposed between the abutting butting terminals and the conducting connection between the butting terminals is not hindered.
Accordingly, the connectivity between the abutting terminals can be maintained well over a long period of time.

  In addition, the spring part that presses the abutting plate part against the mating terminal is protected from external force and has an effect of preventing contact reliability deterioration due to deformation, and the protective wall serves as a guide for the tip positioning piece when the terminal is fitted. The terminals are securely fitted to each other, and the connection reliability is improved.

FIG. 20 is an enlarged view of a portion M in FIG. 19, and FIG.

  The abutting connector 1 of the first embodiment includes an abutting terminal 10 and a pair of connector housings 20 and 30 that accommodate and hold the abutting terminal 10.

  As shown in FIGS. 3 and 4, the abutting terminal 10 includes a terminal main body 11, an abutting plate portion 12, a tip positioning piece 13, and a protective wall 14.

  The terminal body 11 is formed by integrally forming a front end cylindrical portion 111 having a substantially rectangular tube shape and a wire crimping portion 112 extending from the rear end of the front end cylindrical portion 111 by press molding of a metal plate. The terminal main body 11 is inserted into the terminal receiving holes 21 and 31 of the connector housings 20 and 30 and is prevented from coming off by engagement with the lances 22 and 32 in the terminal receiving holes 21 and 31. 31.

  The abutting plate portion 12 has a contact portion 16 on the distal end surface, and is provided so as to protrude from the distal end of the distal end cylindrical portion 111 of the terminal body 11 and is brought into conduction with the mating terminal by being brought into pressure contact with the mating terminal. The abutting plate portion 12 is supported by the terminal body 11 via a spring portion 15 formed integrally with the abutting plate portion 12. The spring portion 15 that supports the butting plate portion 12 to the terminal body 11 is a wave-shaped spring that extends from the butting plate portion 12. The spring portion 15 has a rear end portion 17 locked by an engagement hole 18 provided in the distal end cylindrical portion 111 of the terminal body 11 and supports the abutting plate portion 12 so as to be elastically displaced along the abutting direction.

  The tip positioning piece 13 is a tongue-like piece provided to extend from the tip of the bottom wall portion 111 a of the tip tube portion 111. The tip positioning piece 13 includes an extension plate portion 13a that extends forward from the tip of the bottom wall portion 111a along the abutting direction between the terminals (in the direction of the arrow X1 in FIG. 4), and the extension plate portion 13a. And a positioning piece 13b that rises vertically from the tip perpendicularly to the abutting direction (in the direction of arrow Y1 in FIG. 4).

  The protective wall 14 protrudes from the tip of the terminal body 11 toward the tip positioning piece. The protective wall 14 covers both sides of the butting plate portion 12. In the abutting terminal 10, the mutual tip positioning pieces 13 enter between the tip positioning piece 13 and the abutting plate portion 12 when the abutting terminals 10 are fitted to each other. In the present embodiment, the mutual tip positioning pieces 13 move closer to each other on the circumference around the housing central axes C1 and C2 and enter between the tip positioning piece 13 and the abutting plate portion 12. .

  At this time, each tip positioning piece 13 comes into contact with the counterpart protective wall 14 and is guided. This guide action does not necessarily have to occur, but if there is an error in the relative position between the tip positioning pieces 13 for some reason, the guide action corrects the misalignment, and the tip positioning pieces 13 are mutually offset. However, it smoothly enters between the tip positioning piece 13 and the abutting plate portion 12. Thus, the protective wall 14 has a function of reliably fitting the abutting terminals 10 together to improve contact reliability.

  Moreover, as shown in FIG. 6, since the protective wall 14 covers the both sides of the butting plate part 12, a load is applied to the butting plate part 12 at the time of transportation etc., and it prevents that the spring part 15 deform | transforms. This also has an effect of preventing the contact reliability from being lowered. Furthermore, the movement of the abutting plate part 12 in the lateral direction (Z1 direction in FIG. 7) can be restricted by the protective wall 14 after the fitting between the abutting terminals 10 is completed. For this reason, the protective wall 14 has the function which prevents the contact sliding of the horizontal direction by the vibration of the butting connector 1 compared with the structure which does not have the protective wall 14 shown in FIG.7 (b). Thereby, the raise of the contact part resistance by sliding of the terminal contact parts by the vibration of the connector after a fitting can be suppressed.

  As shown in FIG. 4, the positioning piece portion 13 b of the tip positioning piece 13 forms a gap S <b> 1 between the tip plate portion 111 and the abutting plate portion 12. Both sides of the gap S1 are sandwiched between protective walls 14. The tip positioning piece 13 of the mating terminal that enters the gap S1 enters the gap S1 while being guided by the protective wall 14 as described above. In addition, as shown in FIG. 6, the urging | biasing force by the spring part 15 is acting so that the abutting board part 12 may maintain the state press-contacted to the positioning piece part 13b.

  In other words, the positioning piece 13b moves to the tip side (arrow X1 side in FIG. 4) of the butting plate portion 12 assembled to the tip cylindrical portion 111 (movement of the butting plate portion 12 by the bias of the spring portion 15). ). Further, as shown in FIG. 20 to be described later, the positioning piece 13b is formed by the positioning piece 13b of the mating abutting terminal 10 and the abutting plate 12 by the mutual rotation operation of the connector housing described later. And is engaged with the positioning piece 13b of the mating terminal, and restricts separation in the axial direction with respect to the mating terminal 10 of the mating terminal.

  More specifically, when the distal end positioning piece portion 13b of the mating abutting terminal 10 is interrupted between the positioning piece portion 13b and the abutting plate portion 12 by a rotation operation between the connector housings described later. The end positioning piece 13b and the abutting plate 12 of the abutting terminals 10 are slid together, and the corresponding abutting terminals 10 are abutted against each other (connected state).

  The pair of connector housings 20 and 30 includes terminal receiving holes 21 and 31 into which the abutting terminals 10 are inserted, lances 22 and 32 (see FIG. 15), guide protrusions 23 and guide grooves 33 constituting a guide mechanism, A lock arm 24 and a lock groove 34 constituting a lock mechanism are provided.

  The connector housing 20 is a so-called female housing. As shown in FIG. 1, the connector housing 20 has a cylindrical hood portion 25 that is rotatably fitted to the outer periphery of the front end side of the connector housing 30 that is a male housing, on the distal end side.

  A plurality of terminal receiving holes 21 and 31 are arranged in the connector housings 20 and 30 at predetermined intervals on a circumference centered on the respective housing central axes C1 and C2.

  As shown in FIGS. 15 and 16, the lances 22 and 32 equipped in the connector housings 20 and 30 are provided with the abutting terminals 10 inserted into the terminal receiving holes 21 and 31 of the respective connector housings 20 and 30. The distal end positioning piece 13 and the abutting plate portion 12 are locked at a predetermined position projecting a predetermined length ahead of the respective terminal receiving holes 21 and 31.

  As shown in FIG. 1, the guide protrusion 23 constituting the guide mechanism is a columnar protrusion that protrudes from the inner periphery of the hood portion 25 of the connector housing 20. As shown in FIG. 10, the guide protrusions 23 are provided at two opposing positions on the inner periphery of the hood portion 25.

  The guide groove 33 constituting the guide mechanism is a groove formed on the outer periphery of the connector housing 30, and guides the guide projection 23 when the connector housings 20 and 30 are connected to each other. Regulates the mating operation.

  As shown in FIG. 1, the guide groove 33 includes an axial groove 33a extending along the housing central axis C2, and a circumferential groove 33b formed extending in the circumferential direction from the terminal end of the axial groove 33a. It is configured.

  The axial groove 33a is formed along the housing central axis C2 with a predetermined length from the distal end side of the connector housing 30, and restricts movement of the fitting guide projection 23 in a direction along the housing central axis C2. . As shown in FIG. 10, the axial grooves 33 a are provided at two opposing positions on the outer periphery of the connector housing 20 corresponding to the arrangement of the guide protrusions 23 in the hood portion 25. The terminal end of the axial groove 33a is a slide start position PS that relatively rotates the connector housings 20 and 30 in the circumferential direction. When the guide protrusion 23 reaches the slide start position PS, as shown in FIG. 11, the tip 25a of the hood portion 25 comes into contact with a stepped portion 35a formed on the outer periphery of the connector housing 30, so Further deepening of the fitting is restricted.

  Next, a series of operations when fitting and connecting the connector housings 20 and 30 in the abutting connector 1 described above will be described based on the drawings.

  First, as shown in FIG. 1, the housing central axes C1 and C2 of the connector housings 20 and 30 are aligned with each other, and the position of the guide protrusion 23 on the connector housing 20 is set to the position of the axial groove 33a on the connector housing 30. Accordingly, the connector housing 20 and the connector housing 30 are opposed to each other.

  Next, the connector housings 20 and 30 are fitted to each other, and the guide protrusion 23 is pushed into the axial groove 33a as shown in FIG. At this time, the terminal accommodating hole 21 on the connector housing 20 and the terminal accommodating hole 31 on the connector housing 30 are arranged so as to be displaced in the circumferential direction as shown in FIG.

  When the axial fitting between the connector housing 20 and the connector housing 30 is further deepened, the guide protrusion 23 reaches the slide start position PS as shown in FIG. When the guide protrusion 23 reaches the slide start position PS, the locking protrusion 24b of the lock arm 24 is positioned in the guide groove 34a of the lock groove 34 as shown in FIG. Further, when the guide projection 23 reaches the slide start position PS, the abutting terminals 10 that are the abutting targets in the respective connector housings 20 and 30 are connected to each other as shown in FIGS. The positioning piece portion 13b of the abutting terminal 10 is positioned at an axial position where the positioning piece portion 13b of the other abutting terminal 10 can enter inside the positioning piece portion 13b of the other abutting terminal 10.

  Next, as shown in FIG. 13, the connector housing 20 and the connector housing 30 are rotated so that the guide protrusion 23 moves in the circumferential direction within the circumferential groove 33b from the slide start position PS. As the guide protrusion 23 approaches the end of the circumferential groove 33b, the phase shift angle θ between the terminal receiving holes 21 and 31 between the housings is reduced as shown in FIG. 13B. Further, as shown in FIG. 14, the locking protrusion 24 b of the lock arm 24 moves in the guide groove 34 a of the lock groove 34 toward the moderation ridge 34 c. Further, as shown in FIG. 15 and FIG. 16, the circumferential displacement of the abutting terminals 10 that are the abutting targets in the respective connector housings 20 and 30 is reduced.

  When the relative rotation of the connector housings 20 and 30 further progresses and the guide protrusion 23 reaches the end of the circumferential groove 33b as shown in FIG. 17A, the terminals of the housings are mutually connected as shown in FIG. The positions of the receiving holes 21 and 31 coincide with each other so that the fitting connection between the housings is completed. Further, at this time, as shown in FIG. 18, the locking projection 24b of the lock arm 24 gets over the moderation ridge 34c and engages with the locking groove 34b, and the locked state in which the circumferential movement is restricted. become.

The abutting plate 12 of each abutting terminal 10 is inserted between the positioning piece 13b of the other abutting terminal 10 and the abutting plate 12 and the leading end positioning piece 13 of the abutting abutting terminal 10 is inserted. The abutting connection between the abutting terminals 10 is completed.

  In the case of the abutting connector 1 according to the first embodiment described above, the pair of connector housings 20 and 30 are rotated from the slide start position PS in the circumferential direction perpendicular to the direction of the housing central axes C1 and C2 (slide operation). By doing so, the fitting connection between the connector housings is completed.

  The abutting connection between the abutting terminals 10 when the fitting connection between the connector housings is completed is a sliding operation in which the ends of the abutting terminals 10 are slid together. Does not have a large impact force in the axial direction. Further, the abutting terminals 10 in the abutted state are controlled to be separated from each other in the axial direction with respect to the abutting abutting terminals 10 by the engagement by the tip positioning pieces 13. This prevents the axial load from acting.

  Therefore, it is possible to suppress the occurrence of resin creep on the lances 22 and 32 of each connector housing, and to prevent the contact pressure between the abutting terminals 10 from being lowered by the resin creep of the lances 22 and 32 or the like. Can do.

Further, when the abutting terminals 10 accommodated in the respective connector housings abut each other, the abutting plate portions of the abutting terminals 10 are in a stage before the abutting operation because the tips of the abutting terminals 10 are slid together. Thus, foreign matters such as oxide film and dust adhering to the surface of 12 can be scraped off. Therefore, a foreign object is not interposed between the butting terminals 10 that abut against each other, and the conduction connection between the butting terminals 10 is not hindered.
Therefore, the connectivity between the butting terminals 10 can be favorably maintained over a long period.

  Further, in the case of the abutting connector 1 of the present embodiment, the pair of connector housings 20 and 30 are positioned at the slide start position PS, and then each connector housing is simply rotated around the housing center axes C1 and C2. The connection between the connector housings and the connection between the butting terminals 10 can be completed. Therefore, the operability when connecting the abutting terminals 10 can be improved.

  Further, the spring portion 15 for pressing the abutting plate portion 12 against the mating terminal is protected from external force, and the contact reliability is prevented from being lowered due to deformation. Since it becomes a guide, terminals are securely fitted to each other, and connection reliability is improved. In addition, it is possible to suppress an increase in contact portion resistance due to sliding between the terminal contact portions due to vibration of the connector after fitting.
