JP 2010-80111 A

  In the connector 201 having the above configuration, as a method for connecting the core of the cable C to the cable-side contact, a crimp connection has been widely used. The crimp connection is a method of electrically connecting and fixing the cable C to the cable side contact by sandwiching and caulking the core wire of the cable C with a pair of conductive metal pieces of the cable side contact. In such a crimp-connected connector, a low cost requirement is high and a structure as simple as possible is required. Therefore, the direction in which the cable C is pulled out from the connector is substantially the same as the fitting connection direction of the connectors 210 and 250. (In FIG. 19, the direction perpendicular to the substrate B) is set to simplify the structure. Therefore, when the cable C drawn upward from the cable-side connector 250 is wired in the electronic device, the cable C must be horizontally routed along the surface direction of the substrate B due to restrictions such as space and wiring direction. When it was necessary, the cable C had to be bent or bent to change its direction. However, if the cable C is continuously used after being bent or bent, the cable C may be excessively stressed, causing damage to the connector 201 and the cable C. In particular, the vicinity of the connection portion of the cable C with the cable-side connector 250 is less flexible than the other portions, and there is a problem that the cable C is easily disconnected due to excessive stress.

  The present invention has been made in view of such problems, and in a vertical fitting type connector that is fitted and connected in a direction perpendicular to the surface of the board, the cable crimped and connected to the contact is connected to the surface of the board. It is an object of the present invention to provide a connector device having a structure capable of preventing damage to a connector and a cable with a relatively simple structure even when wiring is performed along the cable.

  To achieve the above object, a connector device according to the present invention includes a cable-side housing (for example, the receptacle housing 60 in the present embodiment) attached to an end of a cable, and a signal line of the cable provided in the housing.

Plug connector in 0), and when the cable side housing and the board side housing are fitted in a direction perpendicular to the board, the cable side contact and the board side contact come into contact, and the cable side connector and the board side connector are The connector device is configured to be electrically connected, and the cable side contact is crimped and connected with the cable signal lines aligned with each other in the axial direction, and the cable side housing and the board side housing are fitted together. The direction and the connection direction of the cable side contact and the signal line are configured to be substantially orthogonal.

  In the connector device having the above-described configuration, the cable-side housing includes a plurality of first cable-side contacts (for example, the first receptacle contacts 80 in the embodiment) and a plurality of second terminals arranged in parallel in two rows in the width direction of the housing. A cable side contact (for example, the second receptacle contact 90 in the embodiment) is attached, and the substrate side housing has a plurality of first substrate side contacts (for example, the first contact in the embodiment in the width direction of the housing). 1 plug contact 30) and a plurality of second substrate side contacts (for example, the second plug contact 40 in the embodiment) are attached, and the first cable side contact and the second cable side contact are shifted by the first distance in the connection direction. And a second distance shifted in the fitting direction, The first board side contact and the second board side contact are formed such that the axial lengths extending in the fitting direction are different from each other by a second distance, and the first board side contact and the second board side contact are shifted by the first distance in the connection direction. When the side housing and the board side housing are fitted in a direction perpendicular to the board, the first cable side contact and the first board side contact come into contact with each other, and the second cable side contact and the second board side It is preferable that the contact comes into contact.

  According to the connector device of the present invention, the cable signal contacts are crimped and connected to the cable side contact in a state in which the axial directions of the cable lines coincide with each other. Since the connection direction of the side contact and the signal line is configured to be substantially orthogonal, the cable crimped to the cable side contact can be drawn and wired in the surface direction of the substrate without being bent or bent. Thus, the connector and cable can be prevented from being damaged with a relatively simple structure.

  In the connector device having the above-described configuration, the first cable side contact and the second cable side contact are shifted by the first distance in the connection direction and shifted by the second distance in the fitting direction. The two board-side contacts are formed so that the axial lengths extending in the fitting direction are different by a second distance, and are shifted by the first distance in the connecting direction so that both the cable-side contact and the board-side contact are respectively Due to the arrangement in two rows, the overall width of the housing is shortened by approximately half compared to the case where each contact is placed in a single row even if the number of signal lines (number of poles) is increased. In addition, it is possible to realize a right angle connector having a two-row arrangement by crimping connection with a simple configuration.

When the receptacle connector 50 is brought close to the plug connector 10 in this way, the left and right fitting guide projections 69 of the receptacle connector 50 are fitted into the left and right fitting guide grooves 29 of the plug connector 10, and the receptacle connector 50 (fitting convex portion 62). ) To the plug connector 10 (fitting recess 27) is guided. At the same time, in the process in which the left and right engaging claws 72 of the receptacle connector 50 are in sliding contact with the left and right inclined surfaces 28 of the plug connector 10, the engaging claws 72 are subjected to the action of the inclined surfaces to the left and right outer sides (both engaging latches). It is elastically deformed in the direction in which the claw 72 is separated. Then, when the locking claw 72 gets over the inclined surface 28, the arm portion 71 that has been bent and deformed to the left and right outwards returns to the original vertical posture by its own restoring elasticity, and the left and right locking claw 72 is left and right. Engages with the locking groove 26. Thus, when the locking claw 72 is engaged with the locking groove 26, an appropriate click feeling is obtained, and at the same time, the fitting convex part 62 is fitted into the fitting concave part 27 and the receptacle housing 60 and the plug housing 20 are fitted. And the receptacle connector 50 and the plug connector 10 are connected to each other.

  At the same time, the contact portion 31 of the first plug contact 30 passes between the contact receptacle 86 of the first receptacle contact 80 and the pair of elastic deformation portions 82 through the contact insertion port 63A of the housing body 61 opened downward. The two points are elastically contacted while being sandwiched between the left and right contact portions 84. Similarly, the contact portion 41 of the second plug contact 40 enters between the pair of elastic deformation portions 92 from the contact receiving port 96 of the second receptacle contact 90 through the contact insertion port 63A of the housing body 61 opened downward, and Two points of contact are made elastically in a state of being sandwiched between the contact portions 94. As a result, the cable C joined to the receptacle contacts 80 and 90 and the substrate B joined to the plug contacts 30 and 40 are electrically connected via the contacts 30, 40, 80 and 90. Thus, signal transmission between both connectors 10 and 50 becomes possible.

  In order to prevent erroneous fitting between the fitting convex portion 62 of the receptacle housing 60 and the fitting concave portion 27 of the plug housing 20, a front wall 25F protruding upward from the base portion 21 is provided upright on the plug housing 20. In the case where the plug housing 20 and the receptacle housing 60 are in the proper orientation, the fitting of both is allowed, and in the case where the plug housing 20 and the receptacle housing 60 are not in the proper orientation, the fitting of both is restricted. (The front wall 25F and the housing main body 61 are in contact with each other so that the fitting convex portion 62 is not fitted into the fitting concave portion 27). A stable connection can be obtained without damaging 30, 40, 80, 90.

  By the way, in order to separate the two connectors 10 and 50 from the state in which the connectors 10 and 50 are fitted and connected in this way, the left and right operation portions 74 of the lock arm 70 are pressed inward (towards each other). The receptacle connector 50 may be pulled out of the plug connector 10 in a state where the engagement between the locking claw 72 of the receptacle connector 50 and the locking groove 26 of the plug connector 10 is released by operation.

  Next, as an application example of the vertical fitting connector 1 according to the present embodiment, a case where the connector 1 is attached to a board for a gaming machine will be described with reference to FIGS.

  For example, a gaming machine board B that controls the operation of a pachinko gaming machine, a revolving gaming machine, or the like is likely to be subject to unauthorized modification such as replacement with a counterfeit ROM or addition / deletion of an unauthorized circuit. In order to prevent such illegal modification and provide it to a fair game, the board B is attached to the gaming machine while being housed and held in the transparent resin board case 100. The substrate case 100 is formed in a substantially rectangular box shape with a case lid attached to the case main body so that the case lid can be opened and closed and detachable, and a housing defined between the case main body and the case lid. The substrate B is accommodated and held in the space 101.

  The board case 100 is formed with a case opening 102 for realizing the fitting / removing operation of the plug connector 10 and the receptacle connector 50 so that the connector 1 is exposed to the outside of the case through the case opening 102. It has become. That is, in a state where the substrate B is accommodated and held in the substrate case 100, the plug connector 10 mounted on the substrate B is exposed to the outside of the case through the case opening 102, and the receptacle connector is passed through the case opening 102. 50 and the plug connector 10 can be fitted and removed in a direction perpendicular to the surface of the substrate B.

  In the state in which the receptacle connector 50 is electrically connected to the plug connector 10, as described above, the fitting connection direction (F) between the plug connector 10 and the receptacle connector 50 and the serial connection direction of the cable C to the receptacle contacts 80 and 90. Since (S) is configured to be orthogonal to each other, the cable C that is crimped to the receptacle contacts 80 and 90 and drawn from the receptacle connector 50 can be wired in the drawing direction without being bent or bent. Therefore, it is possible to prevent damage to the connector 1 and the cable C without causing excessive stress such as bending stress in the cable C. Needless to say, the connector 1 is not limited to a board for a gaming machine, but can be widely applied to boards mounted on other electronic devices.

  As described above, according to the vertical fitting type connector 1 according to the present embodiment, the core wires Ca of the cable C are connected to the receptacle contacts 80 and 90 in a state in which the axial directions of the cables C coincide with each other, that is, in series. Since the fitting connection direction of the plug connector 10 and the receptacle connector 50 and the serial connection direction of the cable to the receptacle contacts 80 and 90 are configured to be orthogonal to each other, the cable connected to the receptacle contacts 80 and 90 by crimping It becomes possible to draw and wire in the surface direction of the substrate B without bending or bending C, and it is possible to prevent damage to the connector 1 and the cable C with a relatively simple structure.

Further, the first plug contact 30 and the second plug contact 40 are shifted by the first distance (D _P1 ) in the series connection direction of the cable C to the contacts 30, 40 and the first plug contact 30 and the second plug contact 40 in the fitting connection direction of the connectors 10, 50. The first receptacle contact 80 and the second receptacle contact 90 are arranged so as to be shifted by two distances (D _P2 ), and the axial lengths extending in the fitting connection direction are different from each other by the second distance (D _R2 ). In this case, the plug contacts 30 and 40 and the receptacle contacts 80 and 90 are both disposed by being shifted by the first distance (D _R1 ) in the series connection direction (that is, D _P1 = D _R1 and D _P2 = D _R2 ). Since each is arranged in two rows, the number of signal lines (number of poles) is increased, compared to the case where each contact is arranged in one row. The overall width of the connector can be reduced to about half, so that the entire connector can be reduced in size, and a right-angle connector with a two-row arrangement by crimp connection can be realized with a simple configuration.

  Although the preferred embodiments of the present invention have been described so far, the scope of the present invention is not limited to those shown in the above-described embodiments. For example, in the above-described embodiment, the number of plug contacts and the number of plug contacts (number of poles) provided in the connector 1 is 26, but this is only an example, and the number of contacts may be any number. .
