Description

  The present invention relates to a connector having a waterproof structure.

  Conventionally, when a connector capable of holding an electric wire is attached to an external device, the electric wire is inserted into a connection recess formed in the device, and the terminal formed on the end of the electric wire is electrically connected to the terminal on the device side. A configuration for connecting to is known. In such a connection structure using a connector, water enters the device through a route passing through the surface of the electric wire (first route) or a route passing through the inner wall surface of the connection hole (second route). there is a possibility. Patent Documents 1 to 3 disclose a connector having a configuration that prevents water from entering the above two paths.

  The connectors of Patent Documents 1 and 2 are configured to prevent water from entering the first path by attaching a cylindrical rubber plug so as to be in close contact with the outer peripheral surface of the electric wire. In addition, this connector prevents water from entering from the second path by attaching a seal ring formed in a frame shape to a portion that contacts the connection hole.

  In Patent Document 3, a plurality of connection holes are formed in the device. Moreover, the connector of patent document 3 is holding | maintaining a some electric wire, and can be attached to an apparatus so that an electric wire may be inserted one each for several connecting holes.

  However, the connector disclosed in Patent Documents 1 and 2 is a part that prevents water from the first path and a part that prevents water from the second path when viewed in a direction perpendicular to the axial direction of the connection hole of the device. Are not arranged overlappingly, the length of the connector in the insertion direction of the connector tends to be long, and it is difficult to make it compact.

  In this regard, the connector disclosed in Patent Document 3 is provided with overlapping portions that prevent water from entering the two paths when viewed in a direction perpendicular to the axial direction of the connection hole. Therefore, it can be said that the configuration of Patent Document 3 can be easily reduced in size by shortening the connector as compared with Patent Documents 1 and 2.

  By the way, the connector of patent documents 1 to 3 is a structure which hold | maintains only an electric wire, Comprising: It does not hold | maintain to the terminal attached to the edge part of an electric wire. Here, in general, in a connector configured to hold a terminal, a terminal holding member (terminal holding unit), a member to which both the terminal holding unit and the seal member are attached, and the like need to be provided at the end of the connector. And the layout becomes complicated. In particular, the cylindrical fitting portion of Patent Document 3 has a simple configuration that prevents water from entering from two paths on the inner peripheral surface and the outer peripheral surface of the cylindrical portion. Therefore, the configuration of Patent Document 3 cannot be applied as it is to a connector having a configuration including a terminal holding portion or the like.

  As described above, it is difficult to reduce the length of the connector in the connector configured to hold the terminal, leaving room for improvement.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector configured to hold a terminal, and to easily reduce the length of the connector.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to an aspect of the present invention, a connector having the following configuration is provided. That is, this connector includes a terminal holding portion and a seal member. The terminal holding portion is inserted into a connection recess formed in an external device, and holds a terminal of an electric wire for connecting to the device. The seal member is inserted into the connection recess and prevents water from entering the device. A mounting portion, a waterproof hole, and a waterproof surface are formed on the seal member. The attachment portion can attach the terminal holding portion. The said waterproof hole can insert the said electric wire, and prevents that water permeates into the said apparatus via the surface of the said electric wire. The waterproof surface is formed at a position at least partially overlapping with the waterproof hole when viewed in a direction perpendicular to the axis of the waterproof hole, and comes into contact with the connection recess from the connection recess. Prevent water from entering the equipment.

  Thereby, since two waterproof locations overlap each other, the length of the connector in the axial direction of the waterproof hole can be suppressed. Further, since the sealing member can be attached to the terminal holding portion, the number of parts can be reduced as compared with a configuration in which a member for supporting the terminal holding portion is separately provided.

  In the connector, it is preferable that there is a place where the attachment portion, the waterproof hole, and the waterproof surface overlap when viewed in a direction perpendicular to the axis of the waterproof hole.

  Thereby, the structure which further shortened the length of the connector in the axial direction of a waterproof hole is realizable.

  In the connector, it is preferable that an insertion hole through which the electric wire can pass is formed in the terminal holding portion in a penetrating manner.

  Thereby, at the time of the assembly of a connector, after attaching a terminal holding part to a sealing member, work, such as inserting an electric wire into both parts, can be performed. That is, since the parts can be assembled at an early stage, the work can be facilitated.

  The connector preferably has the following configuration. That is, the terminal of the said electric wire is flat form, and the protrusion part which protrudes in the width direction of the said terminal is formed. The terminal holding part holds the protruding part.

  Thereby, compared with the structure which hold | maintains the said terminal using the hole formed in the center part of the terminal, the structure which suppressed the length of the terminal is easily realizable. Moreover, since it is not necessary to form a hole in a terminal, the manufacturing cost of a terminal can be reduced.

  The connector preferably has the following configuration. In other words, the connector includes a cylindrical shielding portion that is arranged so as to cover the electric wire and reduces noise generated in a signal flowing through the electric wire. The shielding portion is held by sandwiching an end portion of the shielding portion between two flat members.

  Thereby, since a shielding part can be hold | maintained only by the member of a simple shape, manufacturing cost can be reduced.

  The connector preferably has the following configuration. That is, this connector includes an electric wire holding part. The said electric wire holding part hold | maintains the part located in the outer side of the said apparatus among the said electric wires bent in the substantially perpendicular | vertical state.

  That is, when using a connector configured to hold a wire in a bent state as described above, the amount of protrusion of the connector from the device tends to be a problem. In this respect, the connector of the present invention has two waterproof portions located inside the connection recess, so that the protruding amount of the connector from the device can be suppressed. Therefore, a compact configuration as a whole can be realized.

  Next, embodiments of the present invention will be described with reference to the drawings. First, the configuration of the connector 1 will be described with reference to FIGS. FIG. 1 is a perspective view of a connector 1 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the connector 1. FIG. 3 is a cross-sectional view illustrating the waterproof structure of the connector 1. FIG. 4 is a cross-sectional perspective view showing a structure in which the housing 20 holds the terminal 11. FIG. 5 is a diagram for comparing configurations for holding the terminals 11.

  First, the outline of the connector 1 and the device 100 will be described. The connector 1 of this embodiment holds two electric wires 10. As shown in FIG. 3, the connector 1 is inserted into a connection hole (connection recess) 101 formed in a member (a case, a case, etc. of the device 100) that constitutes a surface portion of the device 100 included in an automobile or the like. Thereby, the connector 1 electrically connects a terminal (not shown) of the device 100 and the electric wire 10. Further, the connector 1 of the present embodiment has a waterproof performance and is configured to prevent water from entering the device 100.

  Hereinafter, a detailed configuration of the connector 1 will be described. As shown in FIG. 2 and the like, the connector 1 includes a housing (terminal holding portion) 20, a seal member 30, a plate-like member 40, a braid fixing member 50, and a braid member (shielding member) 60. It is provided as a configuration. In the following description, the side (terminal 11 side) attached to the device 100 in the connector 1 may be referred to as “device side” and the opposite side may be simply referred to as “non-device side”.

  As shown in FIG. 3, the electric wire 10 includes a conductor portion 10 a and a covering portion 10 b arranged so as to cover the conductor portion 10 a. Further, as shown in FIG. 2 and the like, a terminal 11 is connected to one end side of the electric wire 10. The terminal 11 is configured so that it can be electrically connected to a terminal (not shown) of the device 100. The terminal 11 is formed with a small protruding portion 11 a that protrudes in the width direction from the edge of the terminal 11. In the present embodiment, the protruding direction of the protruding portion 11 a is substantially perpendicular to the longitudinal direction of the electric wire 10. The protrusion 11a is held by the housing 20 as will be described later.

  The housing 20 is made of resin or the like and is a member having an oval cross section. An insertion hole 21 and a holding claw 22 are formed in the housing 20. The insertion hole 21 is configured such that the electric wire 10 can be inserted. As shown in FIG. 4, the holding claw 22 is configured to fix (hold) the terminal 11 by being hooked on the protruding portion 11 a of the terminal 11.

  As a configuration for holding the terminal 11, a configuration in which a holding hole 11x is formed in the terminal 11 and the terminal 11 is held using the holding hole 11x is conventionally known as shown in FIG. 5B. . In the configuration of this comparative example, the holding claw 22x for engaging with the holding hole 11x is formed on the housing 20 side, and the terminal 11 is held by engaging the holding claw 22x and the holding hole 11x. . However, this configuration requires a space for forming the holding hole 11x, and it is considered that the material cost and the like increase due to the increase in the size of the terminal 11. Moreover, since it is necessary to form the holding hole 11x in the terminal 11, there exists a possibility that processing cost may increase. In this regard, in the present embodiment, since the terminal 11 can be held only by the protruding portion 11a, the cost of the terminal 11 can be suppressed.

  The seal member 30 is an elastically deformable rubber member provided to prevent water intrusion into the device 100, and is formed to have an oval cross section like the housing 20. As described above, the route through which water enters the device 100 includes a route that passes through the surface of the electric wire 10 (first route) and a route that passes through the inner wall surface of the connection hole 101 formed in the device 100 (first route). Two routes) are conceivable. The seal member 30 can prevent water from entering from both the paths.

  Hereinafter, a specific configuration of the seal member 30 will be described. As shown in FIG. 2 and the like, the seal member 30 is formed with a housing attachment portion (attachment portion) 31, a waterproof hole 32, a waterproof surface 33, and a plate-like member attachment portion.

  The same number of waterproof holes 32 as the number of electric wires to be held (two in this embodiment) are formed. Each of the waterproof holes 32 is formed in a circular shape and is configured to be in close contact with each outer peripheral surface of the electric wire 10. Specifically, as shown in FIG. 3, a plurality of ring-shaped convex portions are formed side by side on the inner peripheral surface of the waterproof hole 32, and the convex portions contact with the outer peripheral surface of the electric wire 10 to be crushed and sealed. ing. The waterproof hole 32 can prevent intrusion from a route passing through the surface of the electric wire 10.

  The waterproof surface 33 is formed on the outer peripheral surface of the seal member 30. The waterproof surface 33 has a slightly larger diameter than the other outer peripheral surface of the seal member 30, and as shown in FIG. 3, is in contact with the inner wall surface of the connection hole 101 and is crushed by elastic deformation. Thereby, the inundation from the path | route which passes along the inner wall face of the connection hole 101 can be prevented.

  The housing attachment portion 31 is configured as a frame-shaped portion (specifically, an inner peripheral surface of the frame-shaped portion) formed between the waterproof hole 32 and the waterproof surface 33. The inner diameter of the frame-shaped part is configured to be slightly smaller than the outer diameter of the end of the housing 20 on the side opposite to the device. With this configuration, the housing 20 and the seal member 30 can be assembled by elastically deforming the housing attachment portion 31 and attaching it to the end portion of the housing 20.

  Further, in the seal member 30 of the present embodiment, when viewed in a direction perpendicular to the axial direction of the waterproof hole 32, a portion where the three of the housing mounting portion 31, the waterproof hole 32, and the waterproof surface 33 overlap is generated. (Refer to the portion A in FIG. 3). Therefore, the length of the connector 1 in the axial direction can be shortened. In the present embodiment, since the above three positions are all inside the device 100 (connection hole 101), the amount of protrusion of the connector 1 from the device 100 after being attached to the device 100 is also reduced. Can do.

  In the present embodiment, both the seal member 30 and the housing 20 are disposed between the connection hole 101 and the electric wire 10. Therefore, the thickness (rubber thickness) of the seal member 30 can be suppressed as compared with the configuration in which only the seal member 30 is disposed between the connection hole 101 and the electric wire 10.

  The plate-like member attachment portion 34 is a portion for attaching the plate-like member 40 formed at the end of the seal member 30 on the side opposite to the device. The plate-shaped member mounting portion 34 is configured to have an oval cross section, and the plate-shaped member mounting portion 34 is elastically deformed to be fitted into an insertion hole 41 formed in the plate-shaped member 40, thereby providing a seal. The member 30 and the plate-like member 40 can be assembled.

  The plate-like member 40 and the braid fixing member 50 are both metal plate-like members and have a function of supporting the braid member 60.

  The plate-like member 40 is formed with an insertion hole 41, a braid attachment surface 42, a braid attachment hole 43, a shielding terminal 44, and a clamp member attachment portion 45. The braid fixing member 50 is formed with an insertion hole 51, a braid attachment surface 52, and a braid attachment hole 53.

  The braided member 60 is composed of, for example, a member (braided tube, braided shield material) knitted from a metal wire. The braided member 60 is connected to the plate-like member 40 and is grounded via the shielding terminal 44 of the plate-like member 40. With this configuration, it is possible to reduce noise generated in a signal flowing through the electric wire. A brim 61 is formed at the end of the braided member 60 on the device side. The collar portion 61 is configured to be flat, and is formed, for example, by partially folding a braid.

  The insertion hole 41 of the plate-like member 40 is a long hole for assembling the plate-like member 40 and the seal member 30 to each other as described above. Similar to the insertion hole 51 of the braided fixing member 50, the insertion hole 41 can pass the electric wire 10. The braid mounting surface 42 of the plate-like member 40 is configured as a flat surface formed on the surface on the side opposite to the device in the plate-like member 40. The braid mounting surface 52 of the braid fixing member 50 is configured as a flat surface formed on the apparatus side in the braid fixing member 50.

  In order to attach the braided member 60 to the connector 1 with the above configuration, the following may be performed. That is, the worker first arranges the brim portion 61 of the braided member 60 so as to be sandwiched between the braided attachment surface 42 and the braided attachment surface 52. Then, the worker fixes the plate-like member 40 and the braid fixing member 50 by assembling bolts, nuts and the like into the braid mounting hole 43 and the braid mounting hole 53.

  In the case where a metal cylindrical member (cylindrical member) is used instead of the plate member 40 and the braided member 60 is fixed to the outer peripheral surface of the cylindrical member, the outer periphery of the cylindrical member is aligned. It is necessary to create a braid fixing member having a shape. However, since the braided fixing member has a curved shape, the manufacturing cost increases. In this respect, in this embodiment, since the plate-like member 40 can be created simply by processing (punching) a flat plate, the manufacturing cost can be suppressed.

  As shown in FIG. 1, the clamp member attaching portion 45 is formed at an end portion on one side (the lower side in FIG. 1) of the plate-like member 40. A clamp member (electric wire holding portion) 70 can be attached to the clamp member attachment portion 45. The clamp member 70 can be bundled with the electric wire 10 and the braided member 60. By attaching the electric wire 10 and the braided member 60 to the clamp member attaching portion 45 using the clamp member 70, the electric wire 10 and the like can be held in a state bent substantially at a right angle.

  In addition, when adopting a layout in which the electric wire 10 is largely bent immediately after being pulled out from the device 100 in this way, there is often no room in the space around the device 100, so the connector 1 protrudes from the device 100. The size of the part is particularly problematic. In this respect, the connector 1 of the present invention has two waterproof portions located inside the connection hole 101, and therefore, the amount of protrusion of the connector 1 from the device can be suppressed. Therefore, a compact configuration as a whole can be realized.

  Next, a process for assembling the connector 1 will be briefly described. FIG. 6 is a diagram illustrating a process of providing the terminal 11 on the connector 1.

  The operator assembles the housing 20 and the plate-like member 40 to the seal member 30 in advance to form an assembly. Then, the operator passes the electric wire 10 through the assembly, the braid fixing member 50, and the braid member 60 (see FIG. 6A). Since the insertion hole 21 is formed in the housing 20 as described above, the electric wire 10 can pass through the inside of the assembly without any problem.

  Thereafter, the worker presses the terminal 11 to the end of the electric wire 10. Then, the operator holds the protruding portion 11a of the terminal 11 on the holding claw 22 by pulling the electric wire 10 to the non-equipment side (see FIG. 6B). Thereafter, the operator fixes the braided member 60 between the plate-like member 40 and the braided fixing member 50 with a fixing tool such as a bolt in a state where the end of the braided member 60 is sandwiched between the plate-like member 40 and the braided fixing member 50.

  Next, the operator holds the braided member 60 by the clamp member 70 after bending the braided member 60 (and the internal electric wire 10) and positioning it in the vicinity of the clamp member mounting portion 45 (see FIG. 1). As described above, the assembly of the connector 1 is completed.

  If the insertion hole 21 is not formed in the housing 20, the operator passes the electric wire 10 through the seal member 30, presses the terminal 11 to the end of the electric wire, and attaches the terminal 11 to the housing 20. Later, the seal member 30 and the housing 20 are assembled. That is, the housing 20 and the seal member 30 cannot be assembled in advance. In this respect, in this embodiment, since the insertion hole 21 is formed in the housing 20, the housing 20 and the seal member 30 can be assembled | attached previously. Therefore, since it becomes easy to handle a plurality of parts together, workability can be improved.

  As described above, the connector 1 of this embodiment includes the housing 20 and the seal member 30. The housing 20 is inserted into a connection hole 101 formed in the external device 100 and holds the terminal 11 of the electric wire 10 for connecting to the device 100. The seal member 30 is inserted into the connection hole 101 and prevents water from entering the device 100. The seal member 30 is formed with a housing attachment portion 31, a waterproof hole 32, and a waterproof surface 33. The housing attachment portion 31 can attach the housing 20. The waterproof hole 32 allows the electric wire 10 to be inserted, and prevents water from entering the device 100 via the surface of the electric wire 10. The waterproof surface 33 is formed at a position (location A in FIG. 3) at least partially overlapping the waterproof hole 32 when viewed in a direction perpendicular to the axis of the waterproof hole 32, and contacts the connection hole 101. This prevents water from entering the device 100 from the connection hole 101.

  Thereby, since two waterproof locations mutually overlap, the length of the connector 1 in the axial direction of the waterproof hole 32 can be suppressed. In addition, since the housing 20 can be attached to the seal member 30, the number of parts can be reduced as compared with a configuration in which a member for supporting the housing 20 is separately provided.

  Further, in the connector 1 of the present embodiment, when viewed in the direction perpendicular to the axis of the waterproof hole 32, the three of the housing mounting portion 31, the waterproof hole 32, and the waterproof surface 33 are shown at a position A in FIG. 3. Are duplicates.

  Thereby, the structure which further shortened the length of the connector 1 in the axial direction of the waterproof hole 32 is realizable.

  Further, in the connector 1 of the present embodiment, the housing 20 is formed with an insertion hole 21 through which the electric wire 10 can pass.

  Thereby, since the housing 20 and the sealing member 30 can be assembled | attached at the early stage in an assembly process, workability | operativity can be improved.

  Moreover, in the connector 1 of this embodiment, the terminal 11 of the electric wire 10 is flat form, and the protrusion part 11a which protrudes in the width direction of the said terminal 11 is formed. The housing 20 holds the protruding portion 11a.

  Thereby, compared with the structure which hold | maintains the said terminal 11 using the holding hole 11x formed in the center part of the terminal 11, the structure which restrained the length of the terminal 11 is easily realizable. Moreover, since it is not necessary to form the holding hole 11x in the terminal 11, the manufacturing cost of the terminal 11 can be reduced.

  Further, the connector 1 of the present embodiment includes a braided member 60. The braided member 60 is disposed so as to cover the electric wire 10, thereby reducing noise generated in a signal flowing through the electric wire 10. The braided member 60 is held by sandwiching the end portion (the flange portion 61) of the braided member 60 by two flat members (the plate-like member 40 and the braided fixing member 50).

  Thereby, since the braided member 60 can be hold | maintained only with a member of a simple shape, manufacturing cost can be reduced.

  Next, a modification of the above embodiment will be described with reference to FIG. In the following description, components that are the same as or similar to those in the above embodiment are denoted by the same reference numerals as those in the above embodiment, and description thereof is omitted.

  FIG. 7 is a view (front view) of the terminal 11 and the housing 20 of the connector according to the modification as viewed in the axial direction of the insertion hole 21. As shown in FIG. 7, protrusions 11b are formed at both ends in the width direction of the terminal 11 of this modification. The projecting portion 11b of this modification has a shape that is obtained by bending the projecting portion 11a of the terminal 11 of the above-described embodiment at a right angle (in an L shape).

  Further, as shown in FIG. 7, a holding claw 23 is formed in the housing 20 of the present modification. The holding claw 23 of this modification has a shape in which the mounting direction of the holding claw 22 of the above embodiment is varied by 90 °. With this configuration, the holding claw 23 can appropriately hold the protruding portion 11b.

  Since the terminal 11 is bent in this modification, the terminal width of the terminal 11 of this modification is smaller than the terminal width of the terminal 11 of the said embodiment. Therefore, the width of the connector can be reduced by adopting the configuration of this modification.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  The connector 1 is configured to hold two electric wires 10, but the number of electric wires 10 to be held is not limited to this, and may be one or three or more, for example.

  The shape of the seal member 30 is not limited to the example shown above, and can be changed as appropriate as long as the housing mounting portion, the waterproof hole, and the waterproof surface are formed. Moreover, also about components other than the sealing member 30 (the housing 20, the plate-shaped member 40, the braid fixing member 50, etc.), the structure shown above is an illustration, The part or all can be changed suitably.

  The protruding portion 11 a only needs to protrude in the width direction of the terminal 11 (left and right direction in FIG. 5), and is not limited to a shape protruding perpendicular to the longitudinal direction of the electric wire 10.

  In the said embodiment, although it is the structure which bends and holds an electric wire in L shape, this invention is also applicable to the connector of the structure which does not bend an electric wire.

  The present invention is not limited to a connector for sending a signal to an electrical component for control, and can be applied to various connectors such as a power line connector for power supply.
