Description

  The present invention relates to a connector that fits into a mounting hole provided through a case of a device.

  As this type of connector, for example, connectors described in Patent Documents 1 and 2 below are known. The connector described in Patent Document 1 has a configuration in which a terminal accommodation hole is formed through the inside of the housing, and a terminal connected to the end of the electric wire is accommodated in the terminal accommodation hole. A lance is formed inside the terminal receiving hole. On the other hand, the terminal is formed with a lance locking hole for locking the terminal so that the terminal can be loosened by locking with the lance. In this way, there is an advantage that the terminal can be adjusted to an appropriate posture in accordance with the terminal alignment, that is, the position of the terminal block on the device side.

  On the other hand, the connector described in Patent Document 2 includes a molded part that is molded integrally with a terminal, and the molded part fits into a mounting hole of the case. If it does in this way, since it is not necessary to form a lance, there exists a merit that a connector can be reduced in size.

JP 2002-31396 A JP 2008-269858 A

  However, even if the connector can be reduced in size by molding, the terminal cannot be prevented from loosening in the configuration in which the mold portion is fitted into the mounting hole. Therefore, the terminal is forcibly connected to the terminal block on the device side with an incorrect posture, and an excessive load is applied to the terminal. In other words, terminal alignment and connector miniaturization are incompatible problems, and it is difficult to achieve both.

  The present invention has been completed based on the above circumstances, and an object thereof is to achieve both terminal alignment and connector miniaturization.

  The present invention includes a housing that fits into a mounting hole that is provided through a case of a device, a terminal insertion hole that is provided through the inside of the housing, and a free play to the terminal insertion hole from the outside of the case. The terminal inserted in the inserted state and connected to the terminal of the electric wire, the receiving part provided in the housing and extending in the direction intersecting the axial direction of the terminal loose insertion hole, provided in the terminal, and locked to the receiving part Therefore, the terminal is characterized in that it has a retaining projection for retaining the terminal so as to be freely movable.

  According to such a configuration, since the retaining protrusion is provided on the terminal and is locked to the receiving portion, there is no need to provide a lance or a lance locking hole as in the prior art, and the connector can be miniaturized. In addition, since the terminal inserted in the terminal loose insertion hole in a loosely inserted state can be movably retained, the terminals can be aligned.

The following configuration is preferable as an embodiment of the present invention.
When the axial direction of the terminal insertion hole is the front-rear direction, the inner side of the case is the front side, and the outer side of the case is the rear side, the receiving part is formed at the opening edge of the front end opening of the terminal insertion hole, The protrusion may be formed at the front end portion of the molded portion molded integrally with the terminal.
According to such a configuration, it is possible to form a retaining protrusion when the mold part is molded, and it is possible to simplify the structure in which the retaining protrusion is locked to the opening edge of the front end opening of the terminal loose insertion hole.

When the axial direction of the terminal insertion hole is the front-rear direction, the inner side of the case is the front side, and the outer side of the case is the rear side, the receiving part is in front of the rubber plug attached to the rear end opening of the terminal insertion hole. It is good also as a structure which is formed in the front-end part of the front stop part which stops, and the securing protrusion is formed in the rear-end part of a terminal.
According to such a configuration, the retaining protrusion can be locked using the front stop portion that performs the front stop of the rubber stopper.

It is good also as a structure provided with the apparatus side connection piece connected with the apparatus side in a terminal, and the cover which makes a terminal stop before protruding the apparatus side connection piece inside a case.
According to such a configuration, the terminal can be prevented from coming off to the inner side of the case by contacting the terminal with the cover.

  According to the present invention, it is possible to achieve both terminal alignment and connector miniaturization.

<Embodiment 1>
Embodiment 1 of the present invention will be described with reference to the drawings of FIGS. The device connector 10 in the present embodiment is a connector attached to, for example, an inverter device (an example of the “device” in the present invention). The device connector 10 is connected to a terminal of an electric wire 20 that supplies power from a battery (not shown) to the inverter device. Although the inverter device itself is not illustrated, the inverter device is accommodated in a metal case 30 having a shielding function.

  As shown in FIG. 1, the case 30 includes a case main body 31, an upper cover 32 that closes an upper opening that opens at an upper portion of the case main body 31, and the like. A mounting hole 33 is provided through the side wall of the case body 31. The mounting hole 33 is configured by an inner peripheral surface of a fitting cylinder portion 34 that penetrates the side wall of the case body 31 and protrudes to the outside of the case body 31. A terminal block 35 is disposed inside the case 30.

  A terminal 21 is connected to the end of the electric wire 20. The terminal 21 is formed by performing punching or bending by pressing. A device-side connection piece 22 having a flat plate shape is formed on one end side of the terminal 21. The device side connection piece 22 has a bolt hole 23 penetrating in the plate thickness direction. The terminal 21 penetrates the connection bolt B1 through the bolt hole 23 and is connected to the inverter device side so as to be conductive by screwing the connection bolt B1 into the terminal block 35. A barrel portion 24 for caulking the core wire of the electric wire 20 is formed at the base end portion of the device-side connection piece 22.

  The device connector 10 has a housing 11 made of synthetic resin. A plurality of terminal insertion holes 12 are formed through the housing 11. Each terminal 21 can be loosely inserted into each terminal loose insertion hole 12. Each terminal loose insertion hole 12 is partitioned by a partition wall 13. In the following description, the axial direction of the terminal insertion hole 12 is the front-rear direction, the inner side of the case 30 is the front side, and the outer side of the case 30 is the rear side.

  The housing 11 is roughly divided into an internal housing 40 disposed inside the case 30 and an external housing 50 disposed outside the case 30. First, the configuration of the inner housing 40 will be described. The inner housing 40 has a fitting portion 41 that fits into the mounting hole 33. Inside the fitting portion 41, a terminal accommodation hole 12 </ b> A that individually accommodates substantially the latter half of the plurality of terminals 21 is formed. A mounting groove 42 is recessed in the outer peripheral surface of the fitting portion 41. A seal ring 60 is fitted in the mounting groove 42.

  The seal ring 60 is made of rubber having flexibility. The seal ring 60 fitted in the mounting groove 42 is prevented from coming off in a positioning state in the axial direction of the fitting portion 41. When the fitting portion 41 is fitted into the mounting hole 33, the seal ring 60 is in close contact with the mounting groove 42 and the inner peripheral surface of the mounting hole 33. This restricts water from entering the case 30 from between the fitting portion 41 and the fitting cylinder portion 34.

  Next, the configuration of the external housing 50 will be described. The outer housing 50 has a plurality of wire receiving holes 12B having a cylindrical shape. These electric wire accommodation holes 12B individually accommodate the electric wires 20 connected to the respective terminals 21. That is, the terminal loose insertion hole 12 is composed of the terminal accommodating hole 12A and the electric wire accommodating hole 12B, and the terminal accommodating hole 12A and the corresponding electric wire accommodating hole 12B communicate with each other.

  A rubber plug 61 is attached to the rear end opening of the wire receiving hole 12B. The rubber plug 61 is made of rubber having flexibility like the seal ring 60. The rubber plug 61 has a shaft hole, and the electric wire 20 is inserted through the shaft hole. Furthermore, when the rubber plug 61 is inserted into the electric wire receiving hole 12B together with the electric wire 20, the rubber plug 61 comes into close contact with the outer peripheral surface of the electric wire 20 and the inner peripheral surface of the electric wire receiving hole 12B. This restricts water from entering the case 30 from between the outer peripheral surface of the electric wire 20 and the inner peripheral surface of the electric wire housing hole 12B.

  On the rear side of the rubber plug 61, a rubber plug retainer 62 that prevents the rubber plug 61 from being pulled backward is attached. A plurality of holding protrusions 63 are provided on the outer peripheral surface of the rubber stopper presser 62 so as to protrude radially outward. On the other hand, a bending locking piece 52 that can be locked from behind with respect to the holding projection 63 is provided on the inner peripheral surface of the electric wire accommodation hole 12B so as to be able to be bent. When the holding projection 63 is bent and locked to the locking piece 52, the backward movement of the rubber plug retainer 62 is restricted, and the backward removal of the rubber plug 61 is restricted.

  A plurality of front stop portions 53 that perform the front stop of the rubber plug 61 are provided on the inner peripheral surface of the wire receiving hole 12B. The front stop 53 is intermittently arranged in the circumferential direction. The rubber plug 61 is restricted from moving forward by the rear end portion of the front stop portion 53. Therefore, even if the electric wire 20 is inserted into and removed from the electric wire housing hole 12B in the front-rear direction, the rubber plug 61 does not move in the front-rear direction together with the electric wire 20. A predetermined gap is formed between the front stop portion 53 and the outer peripheral surface of the electric wire 20, and the electric wire 20 is allowed to move in the radial direction of the electric wire accommodation hole 12B.

  A metal shield shell 70 having a shield function can be attached to the outer housing 50. The shield shell 70 is configured integrally with a cylindrical portion 71 that surrounds the outer periphery of the outer housing 50, a fixing portion 72 that is fixed to the upper surface of the fitting cylindrical portion 34, and the like.

  The cylinder part 71 is formed in a cylindrical shape having a long hole shape with a horizontally long cross section. At the rear end of the cylindrical portion 71, a flange portion 73 that projects to the inner peripheral side is provided. A portion surrounded by the flange portion 73 is an insertion hole through which the outer housing 50 is inserted. This insertion hole also has a horizontally long slot shape.

  Lock portions 51 can be locked to the upper and lower edges of the flange portion 73, respectively. The lock portions 51 are provided on both upper and lower surfaces of the external housing 50. When the cylindrical portion 71 is fitted to the outer periphery of the outer housing 50, both lock portions 51 are locked to both flange portions 73 from the inner peripheral side. As a result, the shield shell 70 is fixed to the outer housing 50.

  The plurality of electric wires 20 are collectively shielded by the braided wire H. The end of the braided wire H is put on the outer peripheral surface of the cylindrical portion 71, and a caulking ring 80 is crimped so as to cover the braided wire H from the outer periphery. Thereby, it becomes possible to shield the space from the inside of the case 30 to the inside of the braided wire H in a lump without leaking.

  The fixing portion 72 has a form along the upper surface of the fitting cylinder portion 34. A bolt hole is opened in a portion along the upper surface of the fitting cylinder portion 34. The shield shell 70 is fixed to the case 30 by passing the fixing bolt B <b> 2 through the bolt hole and screwing the fixing bolt B <b> 2 into the upper portion of the fitting cylinder portion 34.

  Now, in the range from the barrel portion 24 of the terminal 21 to the base end portion of the device-side connection piece 22, the mold portion 25 is integrally molded. A predetermined gap is formed between the mold part 25 and the inner peripheral surface of the terminal accommodating hole 12A, and the terminal 21 is allowed to move in the radial direction of the terminal accommodating hole 12A.

  A pair of retaining protrusions 26 are formed on both upper and lower sides of the front end portion of the mold portion 25. On the other hand, a rib 43 is provided around the opening edge of the front end opening of the terminal accommodating hole 12A as shown in FIG. A cutout portion (an example of the “receiving portion” of the present invention) 44 that accommodates the retaining projection 26 is recessed at a position corresponding to the retaining projection 26 in the rib 43. When the retaining protrusion 26 is fitted into the notch portion 44, the notch portion 44 is locked to the retaining protrusion 26 from the rear, so that the rearward movement of the mold portion 25 is restricted, and the terminal 21 is prevented from coming off rearward. Is made.

  Here, the protruding height of the retaining protrusion 26 is set so that the retaining state of the retaining protrusion 26 and the notch 44 can be maintained even when the mold portion 25 moves in the vertical direction inside the terminal accommodating hole 12A. ing. Further, a gap is set between the retaining protrusion 26 and the notch 44 so that the device-side connection piece 22 can be aligned.

  A cover 90 is attached to the front end opening of the terminal accommodating hole 12A as shown in FIG. The cover 90 is configured to substantially match the outer shape of the terminal accommodating hole 12A, and is fixed to the inner housing 40 by a locking means (not shown). Further, a terminal insertion hole 91 through which the device-side connection piece 22 is inserted is formed at a position facing the device-side connection piece 22 in the cover 90. As shown in FIG. 1, the device-side connection piece 22 protrudes into the case 30 through the terminal insertion hole 91. The terminal insertion hole 91 is slightly larger than the device-side connection piece 22. For this reason, even when the terminal 21 moves vertically and horizontally inside the terminal accommodating hole 12A, the device side connection piece 22 and the opening edge of the terminal insertion hole 91 are set so as not to interfere with each other.

  The present embodiment has the above-described configuration. Next, an example of a procedure for attaching the device connector 10 will be described. As shown in FIG. 1, a rubber plug retainer 62, a rubber plug 61, a shield shell 70, a housing 11 and the like are passed through the electric wire 20 in advance. From this state, the terminal portion 21 is fixed in a state of being electrically connected to the electric wire 20 by crimping the barrel portion 24 of the terminal 21 to the exposed core wire of the electric wire 20. Subsequently, the braided wire H is fixed in a state of being electrically connected to the shield shell 70 by crimping and crimping the braided wire H between the cylindrical portion 71 and the caulking ring 80.

  Next, the mold part 25 is formed integrally with the terminal 21 by molding the range from the barrel part 24 of the terminal 21 to the base end part of the device-side connection piece 22. On the other hand, on the housing 11 side, the seal ring 60 is fitted in the mounting groove 42. At the same time, the shield shell 70 is attached to the housing 11 from the rear, the cylindrical portion 71 is fitted on the outer housing 50, and the flange portion 73 is locked and fixed to the lock portion 51. Further, the rubber stopper 61 is fixed by inserting the rubber stopper 61 and the rubber stopper holder 62 from the rear side of the outer housing 50 into the electric wire receiving hole 12 </ b> B and locking the holding projection 63 to the locking piece 52.

  In this way, by moving the wire 20 passed through the housing 11 to which the shield shell 70 and the like are assembled while being pulled relatively rearward, the wire 20 is accommodated in the wire accommodation hole 12B, and the terminal 21 is provided. The mold part 25 is accommodated in the terminal accommodating hole 12A from the front. When the mold part 25 is accommodated in the terminal accommodating hole 12A, the retaining protrusion 26 enters the notch 44 from the front, and the retaining protrusion 26 is caught by the notch 44, thereby restricting the rearward movement of the retaining protrusion 26. Is done. Thereby, the terminal 21 is prevented from coming back backward.

  Next, the cover 90 is attached to the front end opening of the terminal accommodating hole 12A from the front. At the time of mounting, the cover 90 is fixed to the inner housing 40 by a locking means (not shown) while the device side connection piece 22 of the terminal 21 is passed through the terminal insertion hole 91. As a result, the device side connection piece 22 protrudes forward from the terminal insertion hole 91, but a predetermined gap is set between the device side connection piece 22 and the opening edge of the terminal insertion hole 91. The device-side connection piece 22 is movable. Further, when the mold part 25 comes into contact with the cover 90 from behind, the terminal 21 is prevented from coming off forward.

  When the assembly of the device connector 10 is thus completed, the fitting portion 41 of the inner housing 40 is inserted into the mounting hole 33 of the case 30. When the fitting portion 41 is inserted into the mounting hole 33, as shown in FIG. 1, the fixing portion 72 of the shield shell 70 attached to the housing 11 is arranged along the upper surface of the fitting cylinder portion 34, and the fixing bolt The shield shell 70 and the housing 11 are fixed to the case 30 by screwing B2 into the upper surface of the fitting tube portion 34 through the bolt hole of the fixing portion 72.

  As a result, the device-side connection piece 22 is disposed along the upper surface of the terminal block 35 and is screwed into the bolt hole of the terminal block 35 through the connection bolt B1 into the bolt hole 23 of the terminal 21 so that the terminal 21 is connected to the terminal block 35. Fixed in an electrically connected state. At this time, since the device-side connection piece 22 is allowed to move freely, the device-side connection piece 22 is corrected to a normal mounting posture as the connection bolt B1 is tightened. Therefore, an excessive load is not applied to the device-side connection piece 22.

  At this time, the case 30, the shield shell 70, and the braided wire H are electrically connected, and the electric wire 20, the terminal 21, and the like are shielded by these. Further, since the seal ring 60 is mounted between the mounting hole 33 and the fitting portion 41 and the rubber plug 61 is mounted between the electric wire housing hole 12B and the electric wire 20, the seal in the case 30 is sealed. Can be planned. Furthermore, the housing 11 does not need to be provided with a lance. As a result, the device-side connection piece 22 does not need to be provided with a lance locking hole, and thus the housing 11 can be downsized. That is, the housing 11 can be reduced in size while ensuring the aligning function of the terminals 21.

  As described above, in the present embodiment, the retaining protrusion 26 is provided on the mold portion 25 formed integrally with the terminal 21, and the retaining protrusion 26 is locked to the notch portion 44. It is not necessary to provide the lance locking hole, and the housing 11 can be downsized. Further, since the terminal 21 inserted in the loose insertion state in the terminal loose insertion hole 12 can be movably retained, the terminal 21 can be aligned. Therefore, according to this embodiment, it is possible to achieve both the alignment of the terminals 21 and the miniaturization of the device connector 10.

  Further, since the retaining protrusion 26 is formed on the mold portion 25 by molding, the retaining protrusion 26 may not be separately formed, and the retaining protrusion 26 can be easily formed. Further, since the notch 44 is formed at the opening edge of the front end opening of the terminal accommodating hole 12A, the retaining protrusion 26 can be easily locked to the notch 44 from the front. Furthermore, the cover 90 can be brought into contact with the mold part 25 to stop the terminal 21 in front, and the device-side connection piece 22 can be protruded forward from the terminal insertion hole 91.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to the drawings of FIGS. Although the device connector 14 of the present embodiment is provided with a retaining protrusion on the terminal 21 like the device connector 10 of the first embodiment, the retaining protrusion and the position where the retaining protrusion is locked are different. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the same components, operations, and effects as those in the first embodiment is omitted.

  Unlike the front stop portion 53 of the first embodiment, the front stop portion 54 that performs the front stop of the rubber plug 61 in the present embodiment is formed shorter in the front-rear direction, as shown in FIG. That is, the front end of the front stop portion 54 of the present embodiment is located behind the front end of the front stop portion 53 of the first embodiment. The front end of the front stop portion 54 is disposed substantially at the center in the front-rear direction of the wire housing hole 12B. As a result, an accommodation space for accommodating a rear substrate portion 27 and a retaining projection 28 described later is formed in front of the front end of the front stop portion 54 in the electric wire accommodation hole 12B.

  The terminal 21 includes a rear substrate portion 27 extending behind the barrel portion 24. The rear substrate portion 27 extends rearward along the axial direction of the electric wire 20, and a pair of retaining projections 28 are erected downward (in a direction intersecting the axial direction of the electric wire 20) at the extended end portion. It is a configuration. Both retaining protrusions 28 are arranged in an opposing state with the electric wire 20 in between. As shown in FIG. 8, the lower end portion of the retaining protrusion 28 can be brought into contact with the front end portions of a pair of front stop portions 54 located on the lower side. The front end portion of the front stop portion 54 has a form extending in a direction intersecting with the axial direction of the wire receiving hole 12B. For this reason, when the electric wire 20 is pulled rearward, the retaining protrusions 28 of the terminal 21 are locked to the front end portions of the front stop portions 54, so that the terminal 21 is prevented from coming back backward.

  As shown in FIG. 6, the cover 92 includes a guide portion 93 that extends rearward along the outer periphery of the terminal 21. The guide portion 93 has a function of guiding the device-side connection piece 22 of the terminal 21 to the terminal insertion hole 91 when the cover 92 is attached from the front to the front end opening of the terminal accommodating hole 12A. For this reason, the inner wall upper surface 93A of the guide portion 93 and the inner wall upper surface 91A of the terminal insertion hole 91 are flush with each other. Therefore, when the device-side connection piece 22 is inserted into the terminal insertion hole 91, the cover 92 is attached to the front end opening of the terminal accommodating hole 12A while the device-side connection piece 22 is in contact with the inner wall upper surface 93A of the guide portion 93. Good.

  As described above, in this embodiment, the retaining projection 28 of the terminal 21 is formed at the rear end portion of the rear substrate portion 27, and the retaining projection 28 is locked to the front end portion of the front retaining portion 54. It is not necessary to mold as in the first embodiment, and the retaining projection 28 can be formed when the terminal 21 is pressed. Further, since the terminal 21 is prevented from coming off by using the front stop portion 54 that performs the front stop of the rubber plug 61, the configuration of the housing 11 does not have to be complicated.
