Description

  The present invention relates to a board connector provided on a printed circuit board, and more particularly to a side connection type board connector to which a mating connector is connected from the side of the printed board, and a mating connector to be connected thereto. .

  As is well known, an electrical connection box such as a junction box mounted on an automobile is provided with a number of connector mounting portions. And the connector of the other party provided in the terminal etc. of the wire harness extended from the electrical component of a motor vehicle is mounted | worn with a connector mounting part.

  Particularly in recent years, with the increase in the number of electrical components mounted on automobiles, a large number of connector mounting portions are provided in the electrical junction box. Therefore, in order to arrange a large number of connector mounting portions in a more space-efficient manner, as described in, for example, Japanese Patent Application Laid-Open No. 2009-153318 (Patent Document 1) and the like, it is opened to the side of the electrical connection box. In some cases, a side connection type substrate connector to which a mating connector is connected from the side of the electrical connection box is provided.

  Such a side connection type substrate connector is provided on a printed circuit board constituting an internal circuit of an electric connection box, as described in Patent Document 1. More specifically, a plurality of board terminals project from the printed circuit board, and the board terminals are formed in an L shape toward the outer peripheral edge of the printed circuit board at an intermediate portion rising from the printed circuit board by a predetermined distance. The connection part with the other party is comprised by bending. And the connection part of these board | substrate terminals is penetrated by the terminal penetration hole penetrated by the synthetic resin housing, and is arrange | positioned in a housing.

  However, in the side connection type board connector as described in Patent Document 1, the intermediate part of the board terminal is bent in an L shape and extended toward the outer peripheral edge of the printed circuit board to constitute the connection part. Therefore, there is a problem that the shape of the board terminal itself is complicated and difficult to handle in the first place, and the arrangement work on the printed board is also difficult. In addition, the board terminal is mounted in a cantilever manner on the printed board, and it becomes difficult to stably hold the board terminal on the printed board. Therefore, it is necessary to mount the board terminal on the printed circuit board by holding the connection part partially by placing it in the terminal insertion hole provided in other members such as a synthetic resin housing or a separate terminal holder. was there. Along with this, it is also necessary to insert the connection portion of each board terminal into the terminal insertion hole of the other member, which causes deterioration in workability and friction caused when the board terminal is inserted into the terminal insertion hole. There was also a problem that the plating was peeled off and the inner surface of the terminal insertion hole was scraped to generate resin scraps.

  Further, since the board terminal is bent in an L-shape toward the outer peripheral edge of the printed circuit board at the intermediate portion rising from the printed circuit board by a predetermined distance, the connecting portion is located above the printed circuit board. It becomes. Therefore, as the rising dimension of the board terminal from the printed board increases, the rising dimension of the side connection type board connector itself from the printed board also increases, leading to an increase in the size of the electrical connection box that accommodates this. There was a problem. In addition, the connection portion of the board terminal needs to be inserted and arranged in the insertion hole of the other member over a predetermined region, and the extension length of the connection portion of the board terminal to the outer peripheral edge portion of the printed board is increased accordingly. Therefore, there is a problem that a space for arranging the side connection type board connector on the surface of the printed board becomes large.

JP 2009-153318 A

  The present invention has been made in the background of the above-mentioned circumstances, and the problem to be solved is that the board terminals can be easily arranged on the printed board without being inserted into and held by other members, and printed. It is an object of the present invention to provide a side-connecting type board connector having a novel structure and a mating connector connected thereto, which can reduce the projecting dimension from the board and the arrangement space on the surface of the printed board.

  A first aspect of the present invention relating to a side connection type board connector is a side connection type board connector in which a mating connector is connected from the side of the printed board, and a plurality of board terminals are provided on the printed board. The intermediate portion is erected without being inserted and held by another member, and is arranged in parallel along the outer peripheral portion of the printed circuit board. The connection terminals of the mating connector are connected to the plurality of circuit board terminals. It is characterized in that it is connected perpendicular to the standing direction of the substrate terminal.

  According to the present invention, the intermediate portion of the board terminal erected on the printed circuit board is used as a connection portion, and the direction perpendicular to the erection direction with respect to the board terminal, that is, the other side connection terminal from the side of the board terminal is Connected. Thus, according to the present invention, the intermediate portion in the standing direction of the board terminal is both bent in an L shape and extended laterally as in the prior art, so that the connecting portion is not provided. This is based on a completely new idea of trying to configure the connection part in the middle part. Thereby, compared with the conventional L-shaped board terminal which has a bending part, handling of a board terminal becomes easy and it becomes unnecessary to hold the board terminal which protrudes in the shape of a cantilever. Therefore, it is not necessary to insert and hold the intermediate portion of the substrate terminal in another member, the manufacturing process can be simplified, and the problem of peeling of the substrate terminal from plating and generation of resin waste during insertion can be solved.

  And the arbitrary positions of the intermediate part in the standing direction of a board | substrate terminal can be set as a connection part. Thereby, compared with the conventional L-shaped board | substrate terminal, a connection part can be set in the position closer to the printed circuit board, and the standup dimension from the printed circuit board of a board | substrate terminal can be reduced. As a result, the projecting dimension of the side connection type board connector from the printed circuit board can be reduced, and thus the height of the electrical connection box that accommodates it can be reduced.

  Further, since the board terminal is erected on the printed board, it is large on the side of the printed board including the region inserted and held in the terminal insertion hole of the other member like the conventional L-shaped board terminal. There is no need to extend. As a result, an arrangement space on the surface of the printed circuit board can be reduced, and a larger effective space of the printed circuit board can be secured.

  In addition, the shape of the connection part provided in the intermediate part of the standing direction of the substrate terminal is arbitrary, for example, the intermediate part of the wire terminal having a rectangular or circular cross section is used as the connection part, or the intermediate part of the flat tab terminal. Can also be used as a connection. It is also possible to integrally provide a so-called tuning fork-shaped connecting portion provided with a tab-shaped connecting portion projecting sideways or a pressure contact blade sandwiching the mating terminal at an intermediate portion of the tab terminal.

  A second aspect of the present invention relating to a side connection type board connector is the one described in the first aspect, wherein each of the plurality of board terminals has a flat plate shape, and the plurality of board terminals are the prints. They are arranged in parallel along the outer peripheral edge of the substrate so as to be spaced apart from each other in the thickness direction.

  According to this aspect, the board width dimension of the flat board terminal can be used as a connection allowance with the mating connector. Thereby, it is possible to effectively secure the connection cost and obtain excellent connection reliability. In particular, the board width direction of the board terminal coincides with the direction in which the insertion / extraction force of the mating connector is applied (direction perpendicular to the outer peripheral edge of the printed board). Since the board terminal is difficult to bend in the board width direction compared to the board thickness direction, it makes a great resistance to the insertion / extraction force applied from the side in the standing direction by skillfully utilizing the shape of the board terminal. It is possible to improve durability.

  A third aspect of the present invention relating to a side connection type board connector is the one described in the first or second aspect, wherein a base end portion of the board terminal has a press-fitting hole provided in the printed board. A press-fit tab to be press-fitted is protruded.

  According to this aspect, the board terminal can be firmly fixed to the printed board by press-fitting the press-fit tab into the press-fit hole of the printed board. As a result, even if a mating connector insertion / extraction force is applied perpendicular to the standing direction of the board terminal, the board terminal can be stably held on the printed board. The number of press-fitting tabs is not limited, and a plurality of press-fitting tabs may be formed. When the insertion part to the through hole of the printed board is press-fitted and fixed to the through hole, the through hole May be used as a press-fitting hole, and the insertion portion may be used as a press-fitting tab.

  According to a fourth aspect of the present invention relating to the side connection type board connector, in the one described in any one of the first to third aspects, a connector housing portion for housing the mating connector is formed. And a housing in which a plurality of terminal holding grooves are formed on the ceiling surface of the connector housing portion, and the housing is covered from above in the standing direction of the board terminals and fixed to the printed circuit board. The plurality of board terminals are disposed in the connector housing portion with the upper end portions inserted into the terminal holding grooves.

  In this aspect, by providing the housing that accommodates the mating connector, the mating connector can be positioned with respect to the board terminal, and a more stable connection can be performed. Further, by inserting the upper end portion of the board terminal into the terminal holding groove of the housing, the upper end portion of the board terminal can be held by the housing when the mating connector is inserted and removed, and stable connection can be made.

  And since a housing is covered from the upper part of a board terminal and it can assemble without inserting a board terminal, while being able to assemble a housing easily, when inserting a board terminal into a housing like the past, It is possible to avoid problems such as plating peeling of the substrate terminal and the possibility of resin scraps being generated due to the housing being shaved. In addition, since the housing can be assembled to the printed circuit board after the board terminals are soldered to the printed circuit board, it is not necessary to use a highly heat-resistant material as a material for forming the housing. Can be reduced.

  A fifth aspect of the present invention relating to a side connection type board connector is the one described in any one of the first to third aspects, wherein a second printed board is disposed facing the printed board. The plurality of board terminals are sandwiched between the printed board and the second printed board, and upper and lower ends of the board terminals are respectively fixed to the printed board and the second printed board. It is what.

  According to this aspect, by skillfully using the two printed circuit boards constituting the printed circuit board laminate in which the printed circuit boards are laminated, the upper and lower ends of the substrate terminal can be supported without requiring any special parts. I can do it. And if the structure of this invention which uses the intermediate part of the standing direction of a board | substrate terminal as a connection part, the board | substrate terminal which connects both printed circuit boards can also be used as a board | substrate terminal of a side connection type board | substrate connector. Further, since a side connection type connector can be formed on the outer peripheral portion of the printed board laminate, for example, the printed board laminate is configured as a unit that can be easily replaced using the side connection board connector. You can also.

  According to a sixth aspect of the present invention relating to a side connection type board connector, in the one described in any one of the first to fourth aspects, a protrusion dimension from the printed board is relatively as the board terminal. A small low-profile terminal and a high-profile terminal having a projecting dimension larger than the low-profile terminal from the printed circuit board are erected on the printed circuit board, and the low-profile terminal and the high-profile terminal are arranged on the outer periphery of the printed circuit board. The high-profile terminals are disposed at the same position in the direction along the portion and are disposed inside the printed circuit board, and the high-profile terminals are formed with extended connection portions that extend toward the outside of the printed circuit board. The extension connecting portion is disposed above the low-profile terminal with a gap.

  In this aspect, the extended connection portion of the high-profile terminal is disposed above the low-profile terminal, and the connection terminal of the mating connector connected to the tall profile terminal is located above the low-profile terminal. Connected to the extension connection. As a result, the low profile terminal and the high profile terminal can be arranged at the same position in the direction along the outer peripheral portion of the printed circuit board, and a larger number of circuit board terminals are arranged in a predetermined area of the outer peripheral portion of the printed circuit board. Can be set. As a result, a higher-density side connection type board connector can be configured.

  In addition, as this aspect, what is necessary is just to include at least two board terminals of a low-profile terminal and a high-profile terminal, and a board terminal including a low-profile terminal and a tall profile terminal is used by combining other board terminals. You may arrange in three or more rows. For example, in the direction along the outer peripheral part of the printed circuit board, the connection part is set to an intermediate height between the low-back terminal and the extended connection part of the high-back terminal between the arrangement intervals of the pair of the low-profile terminal and the high-profile terminal. These three types of substrate terminals may be arranged in three rows, for example.

  A seventh aspect of the present invention relating to a side connection type board connector is the one described in any one of the first to sixth aspects, wherein the board terminal protrudes outwardly from the printed board. A connecting portion is formed.

  According to this aspect, the side connection type board connector can be configured as a male connector in which a connection portion with the mating connector protrudes outward from the printed board. Thus, for example, a printed circuit board provided with a side connection type board connector is configured as a unit that can be easily exchangeably assembled to a printed circuit board provided with a mating connector or an electrical connection box. You can also.

  The present invention relating to a mating connector is a mating connector connected to the side connecting board connector according to any one of the first to seventh aspects of the present invention relating to a side connecting board connector. And the connection terminal has a shape including a pair of press contact blades sandwiching the board terminal of the lateral connection type board connector, and the plurality of connection terminals are partially in the parallel direction of the board terminals. It is characterized by being arranged in a staggered manner overlapping with each other.

  In the mating connector structured according to the present invention, a plurality of connection terminals are arranged closer together by arranging so-called tuning fork-shaped connection terminals having a pair of press contact blades. I can do it. As a result, in the side connection type board connector, the board terminals connected to the connection terminals can be arranged at a narrower pitch, and the side connection type board connector can be formed more compactly.

  According to the present invention related to the side connection type board connector, a plurality of board terminals are erected on the printed board without inserting and holding the intermediate part thereof through another member, and are arranged in parallel along the outer peripheral part of the printed board. The connection terminals of the mating connector are connected to these board terminals perpendicular to the standing direction. Thereby, problems, such as peeling of plating at the time of inserting a board terminal in other members, such as a housing, and the possibility of generation of resin waste, can be avoided. In addition, since the connection part can be set at a position close to the printed circuit board in the standing direction of the printed circuit board terminal, the protruding dimension from the printed circuit board can be suppressed, and the conventional printed circuit board terminal bent into an L-shape. In addition, since it is not necessary to extend greatly to the side of the printed circuit board, the arrangement space on the surface of the printed circuit board can be reduced.

  On the other hand, as shown in FIG. 5, the connector 14 has a structure in which a plurality of tuning fork terminals 62 as connection terminals are accommodated in a connector block 60 having a substantially long rectangular block shape formed of synthetic resin. . The connector block 60 is provided with a plurality of terminal insertion holes 64. The terminal insertion holes 64 are arranged in two rows, and the terminal insertion holes 64 in one row and the terminal insertion holes 64 in the other row are provided. The connector blocks 60 are formed so as to partially overlap each other in the longitudinal direction. Further, in each terminal insertion hole 64, the connector block 60 is opened at the center position in the longitudinal direction in the same direction as the terminal insertion hole 64 over the entire length in the direction orthogonal to the longitudinal direction of the connector block 60. At the same time, an insertion slit 66 extending a predetermined distance in the same direction as the penetrating direction of the terminal insertion hole 64 is formed. Further, locking projections 68 and 68 are formed on both end faces of the connector block 60 in the longitudinal direction.

  The tuning fork terminals 62 are inserted and accommodated in the respective terminal insertion holes 64 of the connector block 60. As shown in FIG. 6 with the connector block 60 omitted, the tuning fork terminal 62 is formed of a metal plate, and at one end, a pair of press contact blades 70, 70 are arranged to face each other with a gap therebetween. It has a tuning fork shape. Although not shown in the figure, the other end 72 of the tuning fork terminal 62 is connected to the other end 72 by soldering an electric wire or by being crimped by a crimp formed on the end 72 as is known in the art. Yes. Then, the tuning fork terminals 62 are inserted into the terminal insertion holes 64 of the connector block 60 from the press contact blades 70, 70 side, and the plurality of tuning fork terminals 62 are placed in the connector block 60 as shown in FIG. 5. The tuning fork terminals 62 in one row and the tuning fork terminals 62 in the other row are displaced from each other in the longitudinal direction of the connector block 60 in the parallel direction of the board terminals 18. Are overlapped and arranged in a staggered pattern. As a result, the gaps between the pressure contact blades 70 of each tuning fork terminal 62 are positioned on the insertion slits 66 and are equally spaced in the longitudinal direction of the connector block 60. The press contact blades 70 are slightly projected into the insertion slit 66.

  As shown in FIG. 1, the side connection type board connector 10 and the connector 14 having such a structure are connected to the connector receiving portion 42 of the side connection type board connector 10 from the side of the printed circuit board 12. Are connected to each other by being inserted. The connector 14 is fixed in a state of being accommodated in the connector accommodating portion 42 by engaging engagement protrusions 68, 68 formed on the connector block 60 with a locking lock 48 formed on the connector accommodating portion 42. The Then, as shown in FIG. 7, each board terminal 18 of the side connection type board connector 10 is inserted into the insertion slit 66 of the connector 14.

  In the side connection type board connector 10 and the connector 14 having the structure according to the present embodiment, the board terminals 18 are erected and arranged in parallel on the outer peripheral portion 16 of the printed circuit board 12. The tuning fork terminal 62 is connected perpendicular to the installation direction. Thus, the connector 14 can be connected from the side of the printed circuit board 12 without bending the board terminal into an L shape and extending to the side of the printed circuit board 12 as in the prior art. Then, by covering the housing 20 from above the board terminal 18 erected on the printed board 12, the connector terminal can be accommodated without inserting the board terminal into the terminal insertion hole of the housing as in the conventional L-shaped board terminal. It can be accommodated in the portion 42. Thereby, the board terminal 18 can be easily accommodated in the housing 20, and the possibility of the occurrence of peeling of the board terminal and the generation of resin waste in the housing, which becomes a problem when the board terminal is inserted into the housing, is avoided. I can do it. Further, by assembling the housing 20 after the board terminal 18 is soldered to the printed circuit board 12, it is avoided that the housing 20 is exposed to the heat of soldering. Therefore, a highly heat-resistant material is used for the housing 20. Becomes unnecessary, and the manufacturing cost can be further reduced.

  Since an arbitrary position of the intermediate portion of the board terminal 18 in the standing direction can be set as the connection part 34 with the tuning fork terminal 62, the connection part 34 can be set close to the printed circuit board 12. Therefore, the protruding dimension of the side connection type board connector 10 from the printed board 12 can be suppressed. Further, the board terminal 18 is erected on the printed circuit board 12, so that it is not necessary to extend greatly to the side of the printed circuit board 12 unlike the conventional L-shaped board terminal. Since it does not protrude, the arrangement space on the surface of the printed circuit board 12 can be reduced, and a larger effective space of the printed circuit board 12 can be secured.

  Furthermore, the substrate terminal 18 has a flat plate shape. Thereby, it is possible to effectively secure a connection allowance with the tuning fork terminal 62 by using the plate width dimension of the substrate terminal 18, and a stable connection can be performed. Further, by using the strength of the board terminal 18 in the plate width direction, a large resistance can be exerted against the insertion / extraction force of the tuning fork terminal 62 applied from the side of the board terminal 18. Further, the press-fitting tabs 26, 26 of the board terminal 18 are press-fitted into the press-fitting holes 38 of the printed circuit board 12, and the upper end edge 28 is inserted into the terminal holding groove 46 of the housing 20. Can be firmly supported.

  On the other hand, in the connector 14, a plurality of tuning fork terminals 62 are arranged in a staggered manner. Thereby, the clearance gap between the press contact blades 70 and 70 into which the board terminal 18 is inserted can be arranged at a narrower pitch in the longitudinal direction of the connector 14.
