Description

  The present invention relates to a connector connection structure, an image processing device, a portable electronic device, and an electrical connector.

  A D-sub connector is known as an example of an electrical connector (see, for example, Patent Document 1). The D-sub connector described in Patent Document 1 is mounted (fixed) on a circuit board.

Japanese Patent No. 2769965

  The circuit board on which the D-sub connector is mounted is housed in a housing of a device such as a PC (Personal Computer). This D-sub connector is exposed to the outside of the housing, and can be connected to a connector (a counterpart D-sub connector) at the tip of a wire harness extending from an external device such as a monitor.

  However, the D-sub connector is fixed to the circuit board, and the position with respect to the housing cannot be changed. For this reason, the freedom degree of attachment of the other party D-sub connector to a D-sub connector is low. Similar problems also exist in electrical connectors other than D-sub connectors.

  In view of the above circumstances, an object of the present invention is to provide a connector connection structure, an image processing device, a portable electronic device, and an electrical connector that can further increase the degree of freedom related to the connection of the electrical connector.

And a conductive member that electrically connects the member and the electrical connector. The electrical connector includes a contact and a housing. The housing includes a fitting portion that can be fitted with a mating connector that is displaced along a predetermined fitting direction, and an electrical connection between the mating connector and the contact fitted in the fitting portion. And an accommodating portion for accommodating the contact so as to allow. The conductive member is electrically connected to the contact and extends from the housing in a direction crossing the fitting direction.

  According to this configuration, the position of the electrical connector with respect to the housing can be easily changed. Therefore, the degree of freedom related to the connection between the electrical connector and the counterpart connector can be further increased.

  (2) Preferably, a plurality of the contacts are arranged in each of a plurality of columns parallel to each other, and positions in the column extending direction are shifted in adjacent columns.

  According to this structure, since it has a some contact, the position with respect to a housing | casing can be changed easily about the electrical connector which requires many connection spaces with the other party connector. Therefore, the degree of freedom related to the connection between the electrical connector and the counterpart connector can be further increased.

  (3) Preferably, when the electrical connector is housed in the housing, the fitting portion is arranged to be hidden in the housing.

  According to this configuration, it is possible to suppress an unnecessary external force from acting on the fitting portion by arranging the fitting portion of the electrical connector so as to be hidden in the housing. More specifically, for example, when an electrical connector is not used, it is possible to prevent foreign matter from coming into contact with the fitting portion. Therefore, damage to the electrical connector can be suppressed.

  (4) Preferably, the housing is configured to be housed in the housing by being displaced along a predetermined first direction with respect to the housing. The connector connection structure further includes a guide portion for guiding the movement of the housing in the first direction within the housing.

  According to this configuration, the electrical connector can be housed in the housing by displacing the housing in the first direction along the guide portion. Therefore, the worker can easily perform the work of housing the electrical connector in the housing. Further, the housing can be held in the guide portion. Therefore, when the electrical connector is not used, the guide unit can hold the electrical connector in the housing.

  (5) Preferably, the connector connection structure further includes a regulating member for regulating an amount of the electrical connector pulled out from the housing.

  According to this structure, it can suppress that the amount of drawing of the electrically-conductive member from a housing | casing becomes excessive. Thereby, since it can suppress that an excessive tensile force acts between a electrically-conductive member and the member supported by the housing | casing, damage to these members can be suppressed more reliably.

  (6) In order to solve the above problems, an image processing apparatus according to an aspect of the present invention includes the connector connection structure and an image processing unit that is electrically connected to the electrical connector and processes an image signal. And.

  According to this structure, the freedom degree regarding the connection of the electrical connector with which the image processing apparatus is equipped can be made higher.

  (7) In order to solve the above problems, a portable electronic device according to an aspect of the present invention includes the connector connection structure described above.

  According to this configuration, the position of the electrical connector with respect to the housing can be easily changed. Therefore, the degree of freedom related to the connection between the electrical connector and the counterpart connector can be further increased.

  (8) In order to solve the above problem, an electrical connector according to an aspect of the present invention includes a contact and a housing. The housing includes a fitting portion that can be fitted with a mating connector that is displaced along a predetermined fitting direction, and an electrical connection between the mating connector and the contact fitted in the fitting portion. A receiving portion for receiving the contact so as to allow; and a guided portion for guiding displacement relative to the housing when the housing is housed and pulled out with respect to a predetermined housing. The displacement direction of the housing with respect to the housing and the fitting direction are directions intersecting each other.

  According to this configuration, the position of the electrical connector with respect to the housing can be easily changed. Therefore, the degree of freedom related to the connection between the electrical connector and the counterpart connector can be further increased.

  According to the present invention, the degree of freedom related to the connection of the electrical connector can be further increased.

  The above is the configuration of the connector connection structure 10. Next, the operation in the connector connection structure 10 will be described. Specifically, (1) an operation of inserting / removing the D-sub connector 50 into / from the housing 2 and (2) an attaching / detaching operation of the D-sub connector 50 and the counterpart D-sub connector 20 will be described. .

[(1) Operation for inserting / removing D-sub connector to / from housing]
FIG. 13A is a plan view of the connector connection structure 10 and shows a state in which the D-sub connector 50 is pulled out from the housing 2. FIG. 13B is a plan view of the connector connection structure 10 and shows a state in which the D-sub connector 50 is housed in the housing 2.

  As shown in FIGS. 2B and 13B, the D-sub connector 50 is housed in the second connector housing portion 17 when not in use. In this case, one side portion 56 d of the housing main body 56 in the D-sub connector 50 is exposed from the second connector housing portion 17. However, other portions of the D-sub connector 50 are hidden in the housing 2. That is, the fitting portion 61 and the like are arranged so as to be hidden in the housing 2. The sliders 63 and 63 of the D-sub connector 50 are fitted with the corresponding guide portions 17 c and 17 c, and the D-sub connector 50 is held in the second connector housing portion 17. In this state, the upper surface 56 a of the housing body 56 extends parallel to the main surface of the circuit board 11. That is, the fitting portion 61 opened to the upper surface 56a is disposed in the second connector housing portion 17 in a lying position.

  The enclosing member main body 67 of the D-sub connector 50 is received by the stopper portion 17 d of the second connector housing portion 17. Thereby, the D-sub connector 50 is positioned in the first direction D1. Further, the cylindrical portion 66 of the sealing member 58 is inserted into the through hole portion 18. The multicore cable 42 is disposed in the first connector housing portion 16 and the second connector housing portion 17, and a part of the multicore cable 42 is disposed in the space 29 of the first connector housing portion 16.

  When using the D-sub connector 50, an operator uses a finger or the like to pinch the housing 51 of the D-sub connector 50 and displace the D-sub connector 50 in the second direction D2. As a result, the D-sub connector 50 is pulled out of the housing 2 as shown in FIGS. 2A and 13A. When the pull-out amount of the D-sub connector 50 reaches a predetermined value, the regulating member 43 is received by the partition wall 16b. As a result, the D-sub connector 50 can no longer be pulled out. At this time, since the load acting on the D-sub connector 50 from the worker is received by the regulating member 43 via the multicore cable 42, it is suppressed from being transmitted to the receptacle connector 12.

  On the other hand, when the D-sub connector 50 is stored in the second connector storage portion 17, the worker arranges the D-sub connector 50 so as to face the second connector storage portion 17. Next, the worker displaces the D-sub connector 50 in the first direction D1. Thereby, as shown to FIG. 2B and FIG. 13B, the sliders 63 and 63 of the D-sub connector 50 and the guide parts 17c and 17c fit. Further, the D-sub connector 50 is housed in the second connector housing portion 17 in the housing 2.

  As shown in FIG. 14, when the D-sub connector 50 is accommodated in the second connector accommodating portion 17, the multicore cable 42 may be twisted so that the upper surface 56 a of the housing 51 faces downward. Also in this case, the pair of sliders 63 and 63 of the D-sub connector 50 are fitted to the corresponding guide portions 17c and 17c. Therefore, the D-sub connector 50 can be stored in the second connector storage portion 17.

By displacing to D3, the counterpart D-sub connector 20 is connected to the D-sub connector 50.

  As a result, the shell 23 of the counterpart D-sub connector 20 is fitted into the fitting portion 61 of the D-sub connector 50. As a result, the shell 23 of the counterpart D-sub connector 20 is fitted into the shell 52 and is electrically connected to the shell 52.

  Further, each contact 22 of the counterpart D-sub connector 20 is inserted into a corresponding accommodation hole 64 of the accommodation portion 62 of the D-sub connector 50. As a result, each contact 22 is sandwiched between the pair of elastic pieces 70, 70 of the corresponding contact 53. As a result, each contact 22 and the corresponding contact 53 are electrically connected. Thus, the accommodating part 62 accommodates the contact 53 so as to allow electrical connection between the contact 22 of the mating D-sub connector 20 fitted to the fitting part 61 and the corresponding contact 53. doing.

  The mating D-sub connector 20 is in a state where it is connected to the D-sub connector 50 by the fitting force of the fitting between the shell 23 and the shell 52 and the fitting between the contact 22 and the corresponding contact 53. Maintained.

  In this state, the image signal from the GPU 9 (see FIG. 2A) is transmitted to the corresponding core wire 42b via the circuit board 11, the receptacle connector 12, and the plug connector 41 shown in FIG. The image signals are further transmitted from the respective core wires 42b to the corresponding signal terminal portions 75 shown in FIG. 12, and further, from the corresponding first through holes 73 as shown in FIG. 9, the corresponding contacts 53, contacts 22, etc. And output to an image display device (not shown). Thereby, the image display apparatus can display the image specified by the image signal.

  When detaching the mating D-sub connector 20 from the D-sub connector 50, the worker displaces the mating D-sub connector 20 in the direction opposite to the fitting direction D3. The connector 20 is pulled out from the D-sub connector 50.

  As described above, according to the wire harness 40 according to the present embodiment, the direction in which each core wire 42b (multi-core cable 42) extends from the enclosing member 58 of the housing 51 is a direction intersecting (orthogonal) with the fitting direction D3. is there. If it is such a structure, when fitting the other party D-sub connector 20 in the fitting part 61 of the housing 51 of the D-sub connector 50, it can suppress that each core wire 42b becomes obstructive. More specifically, since each core wire 42b extends from the enclosing member main body 67 in a direction crossing the fitting direction D3, it is possible to suppress covering the bottom surface of the D-sub connector 50. For this reason, when pushing in the other party D-sub connector 20 in the fitting part 61, it is easy to hold down the bottom face of the housing 51 with a worker's hand or a floor. As a result, it is easy to push the mating D-sub connector 20 into the fitting portion 61. Thereby, it is easy to fit the mating D-sub connector 20 to the fitting portion 61 of the housing 51 of the D-sub connector 50. In particular, in the D-sub connector 50, it is necessary to connect a plurality of contacts 53 to the corresponding contacts 22 of the counterpart D-sub connector 20, so that the counterpart D-sub connector 20 is fitted to the D-sub connector 50. The force required to push into the joint 61 increases. Therefore, the effect of facilitating pushing the mating D-sub connector 20 into the fitting portion 61 is remarkable. As mentioned above, the wire harness 40 which can perform the operation | work which connects the other party D-sub connector 20 and the D-sub connector 50 more easily can be provided.

  Moreover, according to the wire harness 40, in the D-sub connector 50, the thickness L1 of the housing 51 is set smaller than the length L2 of the fitting part 61 in the horizontal direction X1. According to this configuration, the thickness L1 of the housing 51 (D-sub connector 50) can be further reduced. As a result, the housing 51 can be easily handled. Therefore, even in a narrow place, the work of connecting the counterpart D-sub connector 20 to the housing 51 of the D-sub connector 50 can be performed more easily. Moreover, since the housing 51 can be made thinner, the housing 51 (D-sub connector 50) can be accommodated in a thinner space. Thereby, the housing | casing 2 which accommodates the D-sub connector 50 can be made thinner. As a result, the PC 1 can be further reduced in thickness.

  Moreover, according to the wire harness 40, the core wire 42b is covered with the insulating coating | coated part 42a. According to this structure, handling of the core wire 42b can be made easier. Moreover, since the core wire 42b is coat | covered, it can be used regardless of the inside of the housing | casing 2 and the exterior. Therefore, the versatility of the wire harness 40 can be further increased.

  Further, according to the wire harness 40, the substrate 54 of the D-sub connector 50 electrically connects the plurality of contacts 53 and the corresponding core wire 42b. According to this configuration, each core wire 42 b is not configured to be directly connected to the corresponding contact 53. Therefore, the degree of freedom of layout at the other end of each core wire 42b can be further increased. By adopting such a configuration, it is possible to more easily realize a configuration in which each core wire 42b extends from the housing 51 in a direction intersecting (orthogonal) with the fitting direction D3.

  Further, according to the wire harness 40, the other end portion of each core wire 42 b is aligned in parallel with the main surface 54 a of the substrate 54 in each signal terminal portion 75. According to this configuration, the thickness of the space occupied by the plurality of core wires 42b and the substrate 54 as a whole in the vicinity of the housing 51 can be further reduced. As a result, the housing 51 can be made thinner.

  Moreover, according to the connector connection structure 10, the position of the D-sub connector 50 with respect to the housing | casing 2 can be changed easily. Therefore, the freedom degree regarding the connection of the D-sub connector 50 and the other party D-sub connector 20 can be made higher.

  Moreover, according to the connector connection structure 10, since it has the some contact 53, the position with respect to the housing | casing 2 can be easily changed about the D-sub connector 50 which requires many connection spaces with the other party D-sub connector 20. FIG. . Therefore, the freedom degree regarding the connection of the D-sub connector 50 and the other party D-sub connector 20 can be made higher.

  When the D-sub connector 50 is not used, the D-sub connector 50 is stored in the second connector storage portion 17 in the housing 2. Thereby, since the D-sub connector 50 is suppressed from contacting the outside of the housing 2, the external force acting on the D-sub connector 50 can be further reduced. When the D-sub connector 50 is used, the D-sub connector 50 is pulled out from the second connector housing portion 17 and connected to the counterpart D-sub connector 20. The D-sub connector 50 is connected to the circuit board 11 supported by the housing 2 via a flexible core wire 42b and the like. For this reason, when an external force acts on the D-sub connector 50, the external force is released by bending each core wire 42b by the external force. Therefore, even when the D-sub connector 50 is pulled out from the first connector housing portion 16, the external force acting on the D-sub connector 50 can be further reduced.

  Further, according to the connector connection structure 10, when the D-sub connector 50 is housed in the housing 2, the fitting portion 61 of the D-sub connector 50 is disposed so as to be hidden in the housing 2. The According to this configuration, by disposing the fitting portion 61 of the D-sub connector 50 so as to be hidden in the housing 2, it is possible to suppress unnecessary external force from acting on the fitting portion 61. More specifically, for example, when the D-sub connector 50 is not used, it is possible to prevent foreign matter from coming into contact with the fitting portion 61. Therefore, damage to the D-sub connector 50 can be suppressed.

  Moreover, according to the connector connection structure 10, the D-sub connector 50 is housed in the housing 2 by displacing the housing 51 of the D-sub connector 50 in the first direction D1 along the guide portions 17c and 17c. be able to. Therefore, the worker can easily perform the operation of housing the D-sub connector 50 in the housing 2. Further, the housing 51 can be held by the guide portions 17c and 17c. Therefore, when the D-sub connector 50 is not used, the guide portions 17 c and 17 c can hold the D-sub connector 50 in the housing 2.

  Further, according to the connector connection structure 10, the restriction member 43 for restricting the amount of the D-sub connector 50 drawn from the housing 2 is provided. According to this structure, it can suppress that the amount of drawer | drawing-out of each core wire 42b from the housing | casing 2 becomes excessive. Accordingly, it is possible to suppress an excessive tensile force from acting between each core wire 42b and the circuit board 11 supported by the housing 2, and thus the core wire 42b, the circuit board 11, the receptacle connector 12, and the plug connector. The damage to 41 can be more reliably suppressed.

  Depending on the above, the degree of freedom regarding the connection of the D-sub connector 50 provided in the PC 1 can be further increased.

The direction in which each row 65E extends is the vertical direction Y1. In addition, the direction in which the row 65aE and the row 65bE are arranged is the horizontal direction X1. The direction orthogonal to both the vertical direction Y1 and the horizontal direction X1 is the thickness direction Z1.

  A plurality (four in the present embodiment) of the first contacts 113 are arranged in the row 65aE, and a plurality (five in the present embodiment) of the second contacts 114 are arranged in the row 65bE. As well shown in FIGS. 30A and 30B, in adjacent rows (row 65aE and row 65bE), the position of the first contact 113 in the vertical direction Y1 and the position of the second contact 114 in the vertical direction Y1. And are shifted.

  The first contacts 113 have the same configuration. The first contact 113 is an integrally molded product formed by pressing a conductive plate member. The first contact 113 is made of, for example, a copper alloy as a material. The surface of the first contact 113 is subjected to a plating process such as tin plating or gold plating.

  The first contact 113 has a first portion 113 a extending so as to stand upright from the substrate 112 and a second portion 113 b extending toward the opening 121 of the housing 111.

  One end of the first portion 113a is fixed to the first through hole 112a formed in the substrate 112 using solder. A second portion 113b extends from the other end of the first portion 113a. The second portion 113 b is disposed in the shell 116. The 2nd part 113b is provided as an elastic piece part, and has flexibility. A contact portion 113c is formed at the tip side portion of the second portion 113b. The contact portion 113 c can contact the corresponding first contact 104 of the counterpart USB connector 100.

  The second contacts 114 have the same configuration. The second contact 114 is an integrally molded product formed by pressing a conductive plate member. The second contact 114 is formed using the same material as the first contact 113.

  The second contact 114 has a first portion 114 a extending so as to stand upright from the substrate 112 and a second portion 114 b extending toward the opening 121 of the housing 111.

  One end of the first portion 114a is fixed to the second through hole 112b formed in the substrate 112 using solder. A second portion 114b extends from the other end of the first portion 114a. The second portion 114 b is disposed in the shell 116. A tip side portion of the second portion 113b is formed in an L shape. A contact portion 114c is formed in the L-shaped portion. The contact portion 114 c can contact the corresponding second contact 105 of the counterpart USB connector 100.

  As described above, the first contact 113 and the second contact 114 are mounted on the substrate 112. In addition to the first contact 113 and the second contact 114, the substrate 112 has a shell 116 mounted thereon. The substrate 112 is accommodated in the housing body 115. The substrate 112 is provided to electrically connect the plurality of core wires 42b of the multicore cable 42E and the contacts 113 and 114.

  The substrate 112 is a rectangular plate-like member formed using, for example, a printed wiring board. The substrate 112 is disposed near one end (bottom) of the housing main body 115 in the thickness direction Z1. As described above, the substrate 112 has the first through hole 112a and the second through hole 112b. The number of first through holes 112a is the same as the number of first contacts 113, and the number of second through holes 112b is the same as the number of second contacts 114.

  Each first through hole 112a is electrically connected to the core wire 42b of the corresponding multi-core cable 42E. Similarly, each second through hole 112b is electrically connected to the core wire 42b of the corresponding multicore cable 42E. Thus, the core wire 42b is electrically connected to the corresponding contacts 113 and 114.

  The other end of the multi-core cable 42E is embedded in the housing body 115. As described above, the other end of the multicore cable 42E extends from the front end of the housing 111 in the first direction D1 (vertical direction Y1) to the outside of the housing 111 along the first direction D1. That is, the other end of the multicore cable 42E extends from the guide portion 118 of the housing 111E in a first direction D1 (vertical direction Y1) that intersects the fitting direction D3. In the present embodiment, the fitting direction D <b> 3 is a direction parallel to the front-rear direction of the housing 2.

  With the above configuration, the displacement direction (first direction D1 and second direction D2) of the housing 111E with respect to the housing 2E and the fitting direction D3 intersect each other.

  27A and 27B, when the USB connector 50E is housed in the housing 2E, the fitting portion 119 of the housing 111 is disposed so as to be hidden in the housing 2E.

  As described above, according to the wire harness 40E according to the sixth embodiment of the present invention, the direction in which each core wire 42b (multi-core cable 42E) extends from the housing body 115 is a direction intersecting (orthogonal) with the fitting direction D3. (Vertical direction Y1). With such a configuration, when the mating USB connector 100 is fitted to the fitting portion 119 of the housing 111 of the USB connector 50E, it is possible to prevent the core wires 42b from interfering. More specifically, since each core wire 42b extends from the housing main body 115 in a direction intersecting with the fitting direction D3, it is possible to suppress covering the back surface of the USB connector 50E. For this reason, when the counterpart USB connector 100 is pushed into the fitting portion 119, the rear surface of the housing 111E can be easily pressed with the hand of an operator or the like. As a result, it is easy to push the counterpart USB connector 100 into the fitting portion 119. Thereby, it is easy to fit the counterpart USB connector 100 into the fitting portion 119 of the housing 111E of the USB connector 50E. In particular, in the USB connector 50E, it is necessary to connect the plurality of contacts 113 and 114 to the corresponding contacts 104 and 105 of the counterpart USB connector 100. That is, since it is necessary to connect the shells 101 and 116, the force required to push the mating USB connector 100 into the fitting portion 119 of the USB connector 50E increases. Therefore, the effect of facilitating pushing the counterpart USB connector 100 into the fitting portion 119 is remarkable. As described above, it is possible to provide the wire harness 40E that can more easily perform the operation of connecting the counterpart USB connector 100 and the USB connector 50E.

  Moreover, according to the wire harness 40E, the core wire 42b is covered with the insulating coating | coated part 42a. According to this structure, handling of the core wire 42b can be made easier. Moreover, since the core wire 42b is coat | covered, it can be used regardless of the inside and the exterior of the housing | casing 2E. Therefore, the versatility of the wire harness 40E can be further increased.

  Further, according to the connector connection structure 10E, the position of the USB connector 50E with respect to the housing 2E can be easily changed. Therefore, the degree of freedom regarding the connection between the USB connector 50E and the counterpart USB connector 100 can be further increased.

  Further, according to the connector connection structure 10E, since the plurality of contacts 113 and 114 are provided, the position of the USB connector 50E requiring a large connection space with the counterpart USB connector 100 can be easily changed with respect to the housing 2E. Therefore, the degree of freedom regarding the connection between the USB connector 50E and the counterpart USB connector 100 can be further increased.

  When the USB connector 50E is not used, the USB connector 50E is housed in the housing 2E. Thereby, since the USB connector 50E is suppressed from contacting the outside of the housing 2E, the external force acting on the USB connector 50E can be further reduced. When the USB connector 50E is used, the USB connector 50E is pulled out from the housing 2E and connected to the counterpart USB connector 100. The USB connector 50E is connected to the circuit board 11 (not shown in the present embodiment) supported by the housing 2E through a flexible core wire 42b and the like. For this reason, when an external force is applied to the USB connector 50E, each of the core wires 42b is bent by the external force, so that the external force is released. Therefore, even when the USB connector 50E is pulled out from the housing 2E, the external force acting on the USB connector 50E can be further reduced.

  Further, according to the connector connection structure 10E, when the USB connector 50E is housed in the housing 2E, the fitting portion 119 of the USB connector 50E is arranged so as to be hidden in the housing 2E. According to this configuration, by disposing the fitting portion 119 of the USB connector 50E so as to be hidden in the housing 2E, it is possible to suppress an unnecessary external force from acting on the fitting portion 119. More specifically, for example, when the USB connector 50E is not used, it is possible to prevent foreign matter from coming into contact with the fitting portion 119. Therefore, damage to the USB connector 50E can be suppressed.

  Depending on the above, the degree of freedom regarding the connection of the USB connector 50E provided in the PC 1E can be further increased.

  With reference to FIG. 31A and FIG. 31B, in this embodiment, the USB connector 50E is accommodated in the housing 2F in a vertically placed state. Specifically, the thickness L1F of the side part 2cF of the housing 2F is set to be larger than the length L2F of the housing 111 in the lateral direction X1. The opening 2dF of the housing 2F is formed in a vertically long rectangular shape at the side 2cF.

  The USB connector 50E is housed in the housing 2F in a vertically arranged state. Specifically, the housing 111 of the USB connector 50E is arranged so that the fitting direction D3 is downward. In this state, the USB connector 50F is inserted in the housing 2F through the opening 2cF by being displaced in the first direction D1. Thereby, the housing 111 is accommodated in the housing | casing 2F. Also in this case, the multi-core cable 42E extends from the housing 111 in a direction intersecting (orthogonal) with the fitting direction D3.

  Thus, according to the connector connection structure 10F according to the seventh embodiment of the present invention, the USB connector 50E can further reduce the length along the front-rear direction of the housing 2F in the housing 2F. Thereby, since the space for the USB connector 50E in the housing | casing 2F can be narrowed, the length of the housing | casing 2F in the front-back direction of the housing | casing 2F can be made shorter.
