Description

Technical Field

[0001] This disclosure relates to connectors. Background Technology

[0002] As a connector installed at the end of a high-speed communication cable, a connector described in Japanese Patent Application Publication No. 2018-152174 (hereinafter referred to as Patent Document 1) is previously known. The shielded connector described in Patent Document 1 includes shielding terminals and a first housing for inserting the shielding terminals. The shielding terminals include a dielectric body that holds an inner conductor and an outer conductor that surrounds the dielectric body. A first locking portion is formed on the outer conductor by cutting and erecting a portion of its outer surface. The first locking portion locks into a first spear-shaped portion provided in the first housing. A front stop is fitted to the first housing, and when the shielding terminal is inserted into the normal position of the first housing, the front stop presses it into the normal locking position, thereby limiting the flexural deformation of the first spear-shaped portion.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2018-152174 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] Here, considering that in the shielded connector of Patent Document 1, multiple terminals are installed independently of the shielding terminals to form a connector. In cases where the size of the multiple terminals is small, in order to prevent the multiple terminals from detaching from the first housing, it is sometimes preferable to use a sliding stop that moves in the direction in which the multiple terminals are arranged, instead of a front stop that moves relative to the first housing in the insertion / removal direction of the shielding terminals.

[0008] To detect the insertion position of the shielding terminal using the aforementioned stop, it is considered to provide, for example, a recess in the shielding terminal that forms a space for the stop to enter. However, when a hole is provided in the outer conductor to provide the recess in the shielding terminal, the shielding performance of the connector is reduced. Therefore, due to the required shielding performance of the connector, the size of the connector, etc., without providing a hole in the outer conductor, it is not possible to use the stop to detect that the shielding terminal has been properly inserted into the first housing.

[0009] Solution for solving the problem

[0010] The connector disclosed herein comprises: a shielded terminal for connection to a cable, the cable being formed by surrounding the outer periphery of an electrical wire with a shield; a plurality of terminals; a housing for housing the shielded terminal and the plurality of terminals; a stop body held in the housing in a manner movable between a temporary locking position and a permanent locking position in the direction in which the plurality of terminals are arranged, and preventing the plurality of terminals from disengaging from the interior of the housing by moving to the permanent locking position; and a detection member held in the housing in a manner movable between an initial position and a detection position in the insertion / removal direction of the shielded terminal, and moving to the detection position by the permanent position in which the shielded terminal is housed within the housing. The shielded terminal comprises an inner conductor, a dielectric body housing the inner conductor, and a cylindrical outer conductor, the outer conductor covering the outer periphery of the dielectric body and electrically connected to the shield; when the detection member is not located in the detection position, the stop body cannot move to the permanent locking position by interfering with the detection member; when the detection member is located in the detection position, the stop body can move to the permanent locking position.

[0029] [Description of embodiments of this disclosure]

[0030] First, embodiments of this disclosure will be described.

[0031] (1) The connector disclosed herein comprises: a shielded terminal for connection to a cable, the cable being formed by surrounding the outer periphery of an electrical wire with a shield; a plurality of terminals; a housing for housing the shielded terminal and the plurality of terminals; a stop body held in the housing in such a way that it can move between a temporary locking position and a permanent locking position in the direction in which the plurality of terminals are arranged, and preventing the plurality of terminals from disengaging from the interior of the housing by moving to the permanent locking position; and a detection member held in the housing in such a way that it can move between an initial position and a detection position in the insertion / removal direction of the shielded terminal, and moving to the detection position by the permanent position in which the shielded terminal is housed inside the housing, the shielded terminal having an inner conductor, a dielectric body housing the inner conductor, and a cylindrical outer conductor, the outer conductor covering the outer periphery of the dielectric body and electrically connected to the shield; when the detection member is not located in the detection position, the stop body cannot move to the permanent locking position by interfering with the detection member; when the detection member is located in the detection position, the stop body can move to the permanent locking position.

[0032] Based on this structure, the stop body can be moved to the proper locking position, thereby enabling the detection of the proper position of the shielded terminal housed inside the housing.

[0033] (2) Preferably, the connector described above has a cylindrical conductive rubber member that electrically connects the outer conductor and the shield, and has a terminal module consisting of the conductive rubber member, the cable, the inner conductor and the dielectric. When the terminal module is inserted into the outer conductor housed in the housing, the detection member moves from the initial position to the detection position by contacting the terminal module.

[0034] With this structure, by inserting terminal modules inside the outer conductor housed in the housing, it is easy to assemble the shielded terminals and house them in their proper positions within the housing.

[0035] (3) Preferably, the detection member has a locking part and the stop body has a locking part. When the detection member is in the detection position, the locking part moves to the formal locking position through the stop body and engages with the locking part.

[0036] Based on this structure, by detecting the engagement of the locking part of the detection component and the locking part of the stop, it is possible to detect that the shielding terminal has been properly housed inside the housing.

[0037] [Details of the embodiments of this disclosure]

[0038] The embodiments of this disclosure will now be described. This disclosure is not limited to these examples, but is intended to include all variations within the meaning and scope of the claims, as shown by the claims.

[0039] <Implementation Method>

[0040] Reference Figures 1 to 16 Embodiments of this disclosure will be described. The connector 1 of this embodiment is used for wired high-speed communication in a vehicle. In the following description, the direction indicated by arrow Z is upward, the direction indicated by arrow X is forward, and the direction indicated by arrow Y is leftward. Furthermore, regarding multiple identical components, sometimes only some components are labeled with reference numerals, omitting the reference numerals for other components.

[0041] [Connector]

[0042] like Figure 6 As shown, connector 1 includes: a shielded terminal 10; multiple terminals 40; a housing 50 for housing the shielded terminal 10 and the multiple terminals 40; a stop 60 for preventing the multiple terminals 40 from dislodging from the interior of the housing 50; and a detection member 70 for detecting the retraction of the shielded terminal 10 into its proper position. Figure 13 As shown, shielding terminal 10 is connected to the end of cable 2 used for high-speed communication. Figure 16 As shown, terminal 40 is connected to the end of ordinary wire 46. By using connector 1, both high-speed communication transmission paths and ordinary electrical signal transmission circuits can be constructed simultaneously, thus simplifying the design of wiring harnesses in automobiles.

[0043] like Figure 1 As shown, a water-stopping member 9 is provided at the center of the connector 1 in the front-rear direction, covering the outer periphery of the housing 50. The water-stopping member 9 is in close contact with the inner periphery of the cover (not shown) of the mating connector of the connector 1, preventing water from seeping into the space between the housing 50 and the cover.

[0044] [Cables, wires, shielding]

[0045] The cable 2 in this embodiment is used for communication speeds of 100 Mbps or higher, such as... Figure 14 As shown, the cable is formed as a twisted pair (only the ends are shown). The cable 2 has two twisted wires 3. The wires 3 have cores 4 and an insulating sheath 5 covering the outer periphery of the cores 4. The two twisted wires 3 are covered by an insulating layer 6. Further outside the insulating layer 6, a shield 7 and a sheath 8 covering the outer periphery of the shield 7 are provided.

[0046] [Shielded Terminals]

[0047] like Figure 13 and Figure 14As shown, the shielding terminal 10 includes an inner conductor 11, a dielectric 20 that houses the inner conductor 11, and an outer conductor 30 that covers the outer periphery of the dielectric 20.

[0048] [Inner Conductor]

[0049] like Figure 13 As shown, the inner conductor 11 in this embodiment is formed as a female terminal. The inner conductor 11 is manufactured by stamping a sheet metal such as stainless steel. A square-tube-shaped connecting tube portion 12 is provided at the front of the inner conductor 11. A leaf spring portion 13 protruding towards the inside of the connecting tube portion 12 is provided on the upper wall of the connecting tube portion 12. A male terminal (not shown) of the other connector is inserted into the inside of the connecting tube portion 12. This male terminal is formed as an inner conductor that is part of the shielding terminal of the other connector. The male terminal and the inner conductor 11 are electrically connected by contacting the leaf spring portion 13. A locking portion 14 is formed at the rear of the connecting tube portion 12, protruding downward from the outer surface of the connecting tube portion 12. A wire spool 15 electrically connected to the core wire 4 is provided at the rear of the inner conductor 11.

[0050] [Dielectric]

[0051] like Figure 7 , Figure 13 as well as Figure 14 As shown, the dielectric 20 of this embodiment includes a first dielectric 20A and a second dielectric 20B. The first dielectric 20A and the second dielectric 20B are formed of an insulating resin such as polyethylene.

[0052] like Figure 14 As shown, two cylindrical receiving portions 21 are provided through the front of the first dielectric 20A in the front-rear direction. Connecting cylindrical portions 12 of the inner conductor 11 are housed side-by-side in the left-right direction within each cylindrical receiving portion 21. Figure 13 As shown, a locking recess 22 is formed on the lower side of the rear portion of the cylindrical receiving portion 21, and the locking recess 22 locks into the locking portion 14 of the inner conductor 11. Figure 7 As shown, a locking piece 23 is provided above the cylindrical storage portion 21. The locking piece 23 extends rearward from the rear end of the arc-shaped portion 24 provided in the center of the cylindrical storage portion 21 in the front-rear direction, forming a cantilever shape.

[0053] like Figure 7 As shown, a base portion 25 is provided at the rear of the first dielectric body 20A. The base portion 25 has a front engaging portion 25A and a rear engaging portion 25B formed through it in the vertical direction. The front engaging portion 25A and the rear engaging portion 25B engage with the front engaging claw 26A and the rear engaging claw 26B of the second dielectric body 20B, respectively. Figure 13 As shown, the base portion 25 covers the shielding body 7, the insulating layer 6, and the wire 3 at the end of the cable 2 from above. Figure 14 As shown, the front engaging part 25A is configured as a connection part between the inner conductor 11 and the core wire 4, thus making it easy to connect the inner conductor 11 and the core wire 4.

[0054] like Figure 13 As shown, the second dielectric 20B is assembled to the base 25 in such a way that it covers the rear portion of the inner conductor 11, the shield 7 at the end of the cable 2, the insulating layer 6, the wire 3, etc., from below. Figure 14 As shown, the second dielectric 20B has two front engaging claws 26A that engage with the front engaging portion 25A, and two rear engaging claws 26B that engage with the rear engaging portion 25B. A wall-shaped partition 27 protruding from the inner peripheral surface of the second dielectric 20B is provided between the two front engaging claws 26A. The partition 27 separates and insulates the inner conductor 11 and the core wire 4 that are arranged side by side in the left-right direction.

[0055] like Figure 14 As shown, the two rear-side engaging claws 26B have claw-shaped clamping portions 28 protruding inward from their inner peripheral surfaces. The clamping portions 28 are components used to fix the end of the cable 2 disposed inside the dielectric 20 to the dielectric 20. In this embodiment, the clamping portions 28 are configured to clamp the insulating layer 6. A notch (not shown) is provided in the portion of the insulating layer 6 clamped by the clamping portions 28 for positioning the cable 2 and the dielectric 20. Alternatively, the insulating layer 6 may not have the notch, and the clamping portions 28 may clamp it in a pressed state. In other embodiments, the clamping portions may also be configured to clamp a shield, or they may be provided on the inner peripheral surface of the first dielectric.

[0056] [Outer Conductor]

[0057] The outer conductor 30 is made of metals such as zinc alloy, for example Figure 8 As shown, it is constructed in a cylindrical shape. Figure 6 , Figure 13 and Figure 14 As shown, a dielectric 20 assembled within the inner conductor 11 is housed inside the outer conductor 30. The outer conductor 30 is a shielding member against electromagnetic waves radiated from the inner conductor 11 and the core wire 4, as well as electromagnetic waves originating from outside the outer conductor 30. The outer conductor 30 is grounded through contact with a grounding terminal (not shown). Therefore, the induced current generated in the outer conductor 30 due to electromagnetic waves is released to ground. Furthermore, the outer conductor 30 is also electrically connected to the shielding 7 of the cable 2 (described in detail later). Therefore, the induced current generated in the shielding 7 is released to ground via the outer conductor 30.

[0058] The outer conductor 30 is a cast body manufactured by filling a mold with molten alloy metal. More specifically, in this embodiment, the outer conductor 30 is die-cast by injecting molten metal into a mold. The outer conductor 30, being a cast body, is manufactured without holes opening on its peripheral surface, preventing electromagnetic waves from entering or radiating. Therefore, the connector 1 of this embodiment, equipped with the outer conductor 30, has excellent shielding performance.

[0059] like Figure 6 and Figure 13 As shown, a detection protrusion receiving portion 31 is provided in a concave manner on the inner peripheral surface of the upper side and front end of the outer conductor 30. The detection protrusion receiving portion 31 engages with the detection protrusion 73 of the detection member 70, which will be described later. Figure 13 As shown, a locking recess 32 is formed on the outer peripheral surface of the front and lower side of the outer conductor 30 in an upward recessed manner. The locking recess 32 engages with the locking protrusion 63A of the stop body 60. A locking protrusion 33 is provided on the inner peripheral surface of the upper side of the outer conductor 30, protruding downward. The locking protrusion 33 is configured to engage with the locking piece 23 of the dielectric body 20. A receiving portion 34 with an upward and downward expanding diameter is provided at the rear of the outer conductor 30. A conductive rubber member 35 is pressed into the inside of the receiving portion 34, and the conductive rubber member 35 is disposed on the outer periphery of the shield body 7.

[0060] [Conductive rubber components]

[0061] The conductive rubber component 35 is an elastic cylindrical component, constructed by incorporating conductive carbon black or metal powder into various rubber raw materials such as natural rubber or synthetic rubber. For example... Figure 13 As shown, the conductive rubber member 35 is embedded into the end of the cable 2 by means of an expanded diameter, thereby being disposed in close contact with the outer periphery of the shield 7. Furthermore, the conductive rubber member 35 presses against the inner periphery of the housing portion 34 of the outer conductor 30 from within, thus adhering tightly to the inner circumferential surface of the housing portion 34. In other words, the shield 7, from which induced current flows, and the grounded outer conductor 30 are electrically connected through the conductive rubber member 35. Therefore, the conductive rubber member 35 allows the induced current flowing in the shield 7 to be released to ground. Additionally, the conductive rubber member 35 pressed into the housing portion 34 prevents water from seeping into the interior of the outer conductor 30.

[0062] like Figure 13 As shown, the conductive rubber component 35 covers a portion of the shielding body 7 exposed from the sheath 8, and the rear portion of the shielding body 7 not covered by the conductive rubber component 35 is disposed inside the water-stop 36. Unlike this embodiment, the conductive rubber component may also be integrated with the water-stop 36.

[0063] like Figure 13As shown, the water-stop 36 is a cylindrical member disposed on the outer periphery of the end of the cable 2. The outer peripheral surface of the water-stop 36 is pressed against the inner peripheral surface of the housing 50, thereby preventing water from seeping into the interior of the housing 50. The water-stop 36 is located at the position where it connects with the rear end of the conductive rubber member 35. The water-stop 36 has a narrow diameter portion 36A that is pressed against the outer periphery of the shield 7, and a wide diameter portion 36B that is pressed against the outer periphery of the sheath 8. The steps of the narrow diameter portion 36A and the wide diameter portion 36B hook onto the end face of the sheath 8. Thus, the water-stop 36 can be positioned on the cable 2. The front end of the water-stop 36 presses against the conductive rubber member 35. Therefore, water can be effectively prevented from seeping into the shield 7 from the boundary between the water-stop 36 and the conductive rubber member 35.

[0064] The components constituting the shielded terminal 10 are as described above. In this embodiment, the shielded terminal 10 is constructed while assembling the connector 1 by inserting the terminal module 37 into the outer conductor 30 pre-installed in the housing 50 (details to be described later). Here, the terminal module 37 in this embodiment is a component that assembles the cable 2, the water stop 36, the conductive rubber component 35, the inner conductor 11, and the dielectric 20 (see reference). Figure 7 and Figure 12 ).

[0065] The following shows an example of the assembly steps for terminal module 37.

[0066] First, the connecting tube 12 of the inner conductor 11 is inserted into the tube receiving portion 21 of the first dielectric 20A, and the locking portion 14 and the locking recess 22 are formed in a locking state (see reference). Figure 13 Insert the assembled water stop plug 36 and conductive rubber component 35 into the end of cable 2.

[0067] Next, the vertical direction is reversed from the description of the embodiment, but the inner conductor 11 is positioned above the base portion 25 of the first dielectric 20A (in... Figure 13 In the configuration shown by the arrow Z (indicated by the downward orientation), the shield 7 of the cable 2 end, the insulating layer 6, and the wire 3 are placed on the base portion 25, and the core wire 4 is placed on the spool 15. Here, the end of the conductive rubber member 35 and the rear end of the first dielectric 20A are in contact. Next, the spool 15 and the core wire 4 are crimped together (note that, for ease of illustration, in...). Figures 12 to 14 In the middle, the spool 15 and the core wire 4 are not crimped.

[0068] Finally, the second dielectric 20B is assembled onto the first dielectric 20A. That is, the front engaging claw 26A and the rear engaging claw 26B of the second dielectric 20B engage with the front engaging portion 25A and the rear engaging portion 25B of the first dielectric 20A, respectively (see reference). Figure 14At this point, the separator 27 is positioned between the inner conductor 11 and the core wire 4 arranged side-by-side in the left-right direction, and the clamping part 28 clamps and interposed the insulating layer 6. Through the above, the assembly of the terminal module 37 is completed (see reference). Figure 7 ).

[0069] [Multiple terminals]

[0070] like Figure 16 As shown, multiple (as in this embodiment) Figure 6 The three terminals 40 shown are formed as female terminals and are manufactured by stamping a sheet of metal such as brass. Each terminal 40 includes a connecting sleeve portion 41, a leaf spring portion 42, a locking portion 43, a wire spool 44, and further includes an insulating sleeve 45. An unshielded male terminal (not shown) of the other connector is inserted into the connecting sleeve portion 41. This male terminal contacts the leaf spring portion 42, and the multiple terminals 40 and the male terminal are electrically connected. The locking portion 43 engages with a locking receiving portion 52 provided in the housing 50.

[0071] like Figure 16 As shown, multiple terminals 40 are connected to the ends of wire 46. Cable 2 is used for high-speed communication, while wire 46 is used for transmitting ordinary electrical signals or power. Wire 46 has a core wire 47 and an insulating sheath 48 covering the outer periphery of the core wire 47. The core wire 47 is crimped to a wire spool 44, and the insulating sheath 48 is crimped to an insulating cylinder 45. A water-stop plug 49 is provided on the outer periphery of wire 46. The water-stop plug 49 prevents water from entering the interior of housing 50.

[0072] [case]

[0073] The housing 50 is made of insulating synthetic resin, such as Figure 9 As shown, it is block-shaped overall. The front half 50A of the housing 50 is fitted into the other connector. The rear half 50B of the housing 50 is larger than the front half 50A in the vertical and horizontal directions.

[0074] like Figure 9 As shown, on the left side of the front half 50A of the housing 50, three terminal storage portions 51 are arranged side by side in the left-right direction. A locking receiving portion 52, extending vertically through the terminal storage portions 51, is provided above each terminal storage portion 51. A sliding groove portion 53, in a groove-like manner, is provided behind the locking receiving portion 52. The sliding groove portion 53 extends horizontally through the three terminal storage portions 51 in the left-right direction. A mountain-shaped locking protrusion 54, protruding forward, is provided behind the sliding groove portion 53.

[0075] like Figure 16As shown, a plurality of terminals 40 are housed in the terminal housing portion 51, and are engaged by the locking portion 43 and the locking receiving portion 52. The sliding groove portion 53 engages with the sliding wall portion 67 of the stop body 60, which will be described later. On the lower side of the terminal housing portion 51, there is a locking recess 55 that engages with the locking protrusion 63B of the stop body 60, and a locking protrusion housing portion 56 into which the locking protrusion 63A of the stop body 60 is embedded. The locking protrusion housing portion 56 engages with the locking recess 32 of the outer conductor 30 (see reference). Figure 13 Configured in a left-right connected manner. For example... Figures 2 to 4 As shown, the locking protrusion 54 is a structure used to hold the stop 60 in the housing 50 (details to follow).

[0076] like Figure 9 As shown, an outer conductor receiving portion 57 is provided on the right side of the front half 50A of the housing 50. A locking rib receiving portion 58 is provided on the upper wall of the outer conductor receiving portion 57 in a downwardly recessed manner. The locking rib receiving portion 58 is formed to be longer in the front-rear direction. Inside the locking rib receiving portion 58, a leftwardly recessed locking recess 59 is further provided. Figure 15 As shown, the locking recess 59 includes a rear locking recess 59A and a front locking recess 59B disposed in front of the rear locking recess 59A. Figure 6 As shown, the outer conductor 30 is housed in the outer conductor housing portion 57. The engaging rib receiving portion 58 engages with the engaging rib 75 of the detection member 70, which will be described later.

[0077] [Stop body]

[0078] like Figure 1 and Figure 6 As shown, the stop 60 of this embodiment covers the housing 50 from the front, top, bottom, and left, and is slidably mounted on the housing 50 in the left-right direction. As will be described later, the stop 60 prevents the plurality of terminals 40 from detaching from the housing 50, and ensures that the shielded terminals 10 are properly housed inside the housing 50 by means of the detection member 70.

[0079] The stop body 60 is made of insulating synthetic resin, such as Figure 10 As shown, it is a hollow, square box-shaped stop. The stop body 60 includes a stop body side front wall 61, a stop body side top wall 62 extending rearward from the upper end of the stop body side front wall 61, a stop body side bottom wall 63 extending rearward from the lower end of the stop body side front wall 61, and a side wall 64 connecting the left end of the stop body side top wall 62 and the left end of the bottom wall 63. A concave engagement recess 65 is provided in the stop body 60 from the stop body side front wall 61 to the stop body side top wall 62. A through hole 61A extending in the front-rear direction is provided in the stop body side front wall 61. Figure 13 and Figure 16As shown, the through hole 61A is disposed in front of the outer conductor storage part 57 and the terminal storage part 51, and is inserted into the male terminal of the other connector.

[0080] like Figure 10 As shown, a locking protrusion 63A and an engaging protrusion 63B are formed on the bottom wall 63, extending upwards in a left-right direction. The locking protrusion 63A is located on the front side of the bottom wall 63 and covers approximately the entire area of ​​the bottom wall 63 in a left-right direction. The engaging protrusion 63B is located on the rear side and left side of the bottom wall 63. Figure 13 As shown, the right side portion of the locking protrusion 63A engages with the locking recess 32 of the outer conductor 30, as... Figure 16 As shown, the left side portion of the locking protrusion 63A is embedded into the locking protrusion receiving portion 56 of the housing 50. In addition, the engaging protrusion 63B engages with the engaging recess 55 of the housing 50.

[0081] like Figure 10 As shown, a temporary locking recess 66A and a permanent locking recess 66B are formed at the rear end of the left side of the top wall 62 and bottom wall 63 of the stop body, respectively, in a forward-facing concave shape. The temporary locking recess 66A is disposed to the right of the permanent locking recess 66B, spaced apart from it in the left-right direction. Figures 2 to 4 As shown, the temporary locking recess 66A and the permanent locking recess 66B are engaged with the locking protrusion 54 of the housing 50 (see reference). Figure 9 (Not shown, but a locking protrusion 54 is also provided on the underside of the housing 50.)

[0082] [Temporary stop position, Official stop position]

[0083] like Figure 2 and Figure 3 As shown, when the locking protrusion 54 and the temporary locking recess 66A are engaged, the position of the stop body 60 relative to the housing 50 is formed as a temporary locking position. Figure 4 As shown, with the locking protrusion 54 and the formal locking recess 66B engaged, the position of the stop body 60 relative to the housing 50 is formed as the formal locking position. As described above, the stop body 60 and the housing 50 have a mutually engaging structure, so the stop body 60 is held in the housing 50 in a manner that allows it to move in the left-right direction (the direction in which the plurality of terminals 40 are arranged) between the temporary locking position and the formal locking position.

[0084] like Figure 10 As shown, a sliding wall portion 67 is provided on the lower surface of the rear side of the top wall 62 of the stop body, protruding downwards. The sliding wall portion 67 has an anti-slip portion 67A extending further downwards from the sliding wall portion 67. Three anti-slip portions 67A are provided at intervals in the left-right direction. That is, the sliding wall portion 67 is generally comb-shaped. Figure 16As shown, the sliding wall portion 67 engages with the sliding groove portion 53 of the housing 50. When the stop body 60 is in the fully engaged position, the anti-disengagement portion 67A is disposed inside the terminal storage portion 51 of the housing 50 and interferes with the connecting sleeve portion 41 of the plurality of terminals 40. This prevents the plurality of terminals 40 from disengaging from the interior of the housing 50.

[0085] On the other hand, when the stop 60 is in the temporary locked position, the anti-detachment part 67A is not disposed inside the terminal storage part 51, so multiple terminals 40 can be inserted into the interior of the terminal storage part 51 (illustration omitted). That is, multiple terminals 40 can enter between the anti-detachment parts 67A or the space to the right of the anti-detachment parts 67A (see reference). Figure 10 ).

[0086] [The part that was blocked]

[0087] like Figure 10 As shown, a locking portion 69 with a concave-convex shape is provided at the right end of the front side of the stop body side top wall 62. The locking portion 69 has a concave locking portion 69A that is recessed to the left and a convex locking portion 69B that protrudes to the right. The concave locking portion 69A and the convex locking portion 69B are formed connected in the front-rear direction, and the inner surface of the front side of the concave locking portion 69A also serves as the outer surface of the convex locking portion 69B. Figure 4 As shown, the engaging part 69 engages with the engaging part 74 of the detection member 70, which will be described later.

[0088] [Detection Components]

[0089] like Figure 1 As shown, in this embodiment, the detection member 70 is embedded in the engagement recess 65 of the stop body 60, and together with the stop body 60, covers the housing 50 from above and the front. As will be described later, the detection member 70 is a member used to detect that the shielding terminal 10 has been properly housed inside the housing 50.

[0090] The detection component 70 is made of insulating synthetic resin, such as Figure 11 As shown, it is frame-shaped. The detection member 70 has a detection member side front wall 71 and a detection member side top wall 72 extending rearward from the upper end of the detection member side front wall 71. A detection protrusion 73 protruding rearward is provided at the lower end of the left side of the detection member side front wall 71. Figure 6 As shown, the detection protrusion 73 engages with the detection protrusion receiving portion 31 of the outer conductor 30.

[0091] [Initial location, detection location]

[0092] like Figure 11As shown, a downwardly protruding and front-rear extending locking rib 75 is provided on the lower surface of the left side of the top wall 72 of the detection component. A mountain-shaped locking protrusion 76 protruding to the left is formed on the locking rib 75. Figure 6 As shown, the engaging rib 75 engages with the engaging rib receiving portion 58 of the housing 50. (As indicated...) Figure 15 As shown, the locking protrusion 76 engages with the locking recesses 59, namely the rear locking recess 59A and the front locking recess 59B, provided on the locking rib receiving portion 58. With the locking protrusion 76 and the rear locking recess 59A engaged, the position of the detection member 70 relative to the housing 50 (indicated by the solid line) is formed as the initial position. With the locking protrusion 76 and the front locking recess 59B engaged, the position of the detection member 70 relative to the housing 50 (indicated by the double-dotted line) is formed as the detection position. The detection member 70 is held in the housing 50 in a manner that allows it to move between the initial position and the detection position in the front-to-back direction (the insertion / removal direction of the shielding terminal 10).

[0093] The initial position is where the detection component 70 is assembled in the housing 50 before the shielding terminal 10 is housed in the housing 50, according to the sectional view viewed from the side. Figure 12 The position shown. On the other hand, the detection position is the position where the detection component 70 interferes with the shielding terminal 10, and the position where the detection component 70 is pushed forward is the position where the shielding terminal 10 is housed inside the housing 50 in a normal position. Figure 13 The position shown. The mechanism for moving the detection component 70 from the initial position to the detection position, together with the assembly method of the connector 1, is described in detail below.

[0094] like Figure 11 As shown, a locking portion 74 with a concave-convex shape is provided at the left end of the rear side of the top wall 72 of the detection component. The locking portion 74 has a convex locking portion 74A protruding to the left and a concave locking portion 74B recessed to the right. The convex locking portion 74A and the concave locking portion 74B are formed connected in the front-rear direction, and the inner surface of the rear side of the concave locking portion 74B also serves as the outer surface of the convex locking portion 74A. Figure 4 As shown, the convex engaging portion 74A engages with the concave engaging portion 69A, and the concave engaging portion 74B engages with the convex engaging portion 69B respectively.

[0095] The components constituting connector 1 are as described above. The following describes in detail an example of the assembly steps of connector 1 in this embodiment and an example of the method for detecting the proper placement of shielding terminal 10 into housing 50.

[0096] First, the outer conductor 30 and the water-stopping component 9 are assembled in the housing 50. The outer conductor 30 is inserted into the outer conductor receiving part 57 from the rear of the housing 50.

[0097] Next, the stop 60 is assembled to the housing 50. The stop 60 is engaged by the sliding wall portion 67 and the sliding groove portion 53, by the locking protrusion 63A and the locking protrusion receiving portion 56, and by the locking protrusion 63B and the locking recess 55 (see reference). Figure 16 The stop body 60 is slidably mounted relative to the housing 50 in the left-right direction. It is held in a temporary locked position by the temporary locking recess 66A and the locking protrusion 54 (see reference). Figure 2 Additionally, the locking protrusion 63A of the stop body 60 engages with the locking recess 32 of the outer conductor 30 (see reference). Figure 12 ).

[0098] Next, the detection component 70 is assembled into the housing 50. The detection component 70 is engaged by the engaging rib 75 and the engaging rib receiving portion 58, and by the engaging of the detection protrusion 73 and the detection protrusion receiving portion 31 of the outer conductor 30 (see reference). Figure 6 It is slidably mounted relative to the housing 50 in the front-rear direction. For example... Figure 15 As shown by the solid line, the detection component 70 is held in its initial position by being engaged by the locking protrusion 76 and the rear locking recess 59A (see reference). Figure 2 and Figure 12 ).

[0099] Multiple terminals 40, which are connected to the ends of wires 46, are inserted into the terminal receiving portion 51 from the rear of the housing 50. The multiple terminals 40 are held in the terminal receiving portion 51 by locking portions 43 and 52 (see reference). Figure 16 Terminal module 37 is recessed into the outer conductor 30 of housing 50 from the rear direction (see reference). Figure 12 ).like Figure 13 As shown, the shielding terminal 10 is assembled by being secured by the locking tab 23 and the locking protrusion 33. That is, Figure 13 Terminal module 37 shown (refer to) Figure 7 and Figure 12 The position of terminal module 37 relative to outer conductor 30 is the normal position, and Figure 13 The position of the shielding terminal 10 shown is the normal position of the shielding terminal 10 relative to the housing 50.

[0100] However, unlike this embodiment, in existing structures lacking detection components, it is difficult to confirm that the terminal module has been properly inserted into the outer conductor. This is because the outer conductor of the shielded terminal lacks holes, making it difficult to increase the locking amount of the dielectric retaining tabs and the outer conductor retaining protrusions, even considering connector thinning. Furthermore, pressing the water-stop plug located around the cable periphery into the housing and the conductive rubber component into the outer conductor's receiving portion requires considerable insertion force. Therefore, based on the feel of inserting the terminal module into the outer conductor, it is difficult to determine the locking of the dielectric retaining tabs and the outer conductor retaining protrusions, i.e., whether the terminal module is properly inserted. Moreover, even using a sliding stop to prevent multiple terminals from detaching makes it difficult to guarantee the insertion position of the shielded terminal.

[0101] In this embodiment, when the terminal module 37 is inserted into the outer conductor 30, the arc-shaped portion 24 at the base end of the locking piece 23 contacts the detection protrusion 73 of the detection member 70, thereby pushing the detection member 70 forward as the terminal module 37 is inserted (see reference). Figure 12 and Figure 13 Furthermore, when the terminal module 37 is inserted into the proper position of the outer conductor 30 (i.e., when the shielding terminal 10 is completed and housed in the proper position of the housing 50), the detection member 70 is positioned in the detection position (see reference). Figure 3 , Figure 13 ,and Figure 15 (The double-dotted section). Therefore, in this embodiment, the detection member 70 can be used to detect that the shielding terminal 10 has been stored in the correct position. On the other hand, as Figure 12 As shown, when the terminal module 37 is inserted in the middle, the detection member 70 does not move from the initial position, or even if it moves, it is positioned in the middle of the initial position and the detection position.

[0102] Finally, with the detection component 70 already moved to the detection position, the stop body 60 is moved to the right to move from the temporary locking position (see reference). Figure 3 Move to the official stop position (refer to) Figure 4 This prevents the multiple terminals 40 from detaching. Here, in the state where the detection member 70 has not reached the detection position (e.g., Figure 12 In the state shown, if the stop body 60 is about to be mistakenly moved to the proper locking position, such as Figure 5 As shown, the engaging portion 74 of the detection component 70 and the engaged portion 69 of the stop 60 cannot engage, but interfere with each other, therefore the stop 60 cannot move to the proper locking position. On the other hand, as Figure 4As shown, with the detection member 70 positioned in the detection position, the stop 60 can move to the proper locking position, where the engaging portion 74 and the engaged portion 69 engage. Therefore, in this embodiment, the proper position in which the shielding terminal 10 is housed inside the housing 50 can also be detected by the sliding stop 60.

[0103] [Effects of the Implementation Method]

[0104] According to the implementation method, it achieves the following effects.

[0105] The connector 1 of the embodiment includes: shielded terminals 10 for connecting a cable 2, the cable 2 being surrounded by a shield 7 around the periphery of an electrical wire 3; a plurality of terminals 40; a housing 50 for housing the shielded terminals 10 and the plurality of terminals 40; a stop 60 held in the housing 50 such that it can move between a temporary locking position and a permanent locking position in the direction in which the plurality of terminals 40 are arranged, and prevents the plurality of terminals 40 from dislodging from the interior of the housing 50 by moving to the permanent locking position; and a detection member 70 for inserting or removing the shielded terminals 10 between an initial position and a detection position. The directional movement is maintained in the housing 50, and moves to the detection position through the shield terminal 10 housed in the normal position inside the housing 50. The shield terminal 10 has an inner conductor 11, a dielectric body 20 that houses the inner conductor 11, and a cylindrical outer conductor 30. The outer conductor 30 covers the outer periphery of the dielectric body 20 and is electrically connected to the shield body 7. When the detection member 70 is not in the detection position, the stop body 60 cannot move to the normal locking position due to interference with the detection member 70. When the detection member 70 is in the detection position, the stop body 60 can move to the normal locking position.

[0106] According to the above structure, the stop body 60 can be moved to the proper locking position, thereby detecting that the shielding terminal 10 has been properly housed inside the housing 50.

[0107] The connector 1 of the embodiment includes a cylindrical conductive rubber member 35 that electrically connects the outer conductor 30 and the shield 7. The terminal module 37 is formed by the conductive rubber member 35, the cable 2, the inner conductor 11 and the dielectric 20. When the terminal module 37 is inserted into the outer conductor 30 housed in the housing 50, the detection member 70 moves from the initial position to the detection position by contacting the terminal module 37.

[0108] According to the above structure, by inserting the terminal module 37 inside the outer conductor 30 housed in the housing 50, the assembly of the shielding terminal 10 and the storage of the shielding terminal 10 in the proper position of the housing 50 can be easily performed.

[0109] In the embodiment, the detection member 70 has a locking part 74 and the stop body 60 has a locking part 69. When the detection member 70 is in the detection position, the locking part 69 moves to the formal locking position through the stop body 60 and engages with the locking part 74.

[0110] Based on the above structure, by detecting the engagement of the engagement portion 74 of the detection member 70 and the engagement portion 69 of the stop body 60, it is possible to detect that the shielding terminal 10 has been properly housed inside the housing 50.

[0111] <Other Implementation Methods>

[0112] (1) In the above embodiment, the connector 1 has a water-stopping component 9 and a water-stopping plug 36 and 49, but it is not limited to this. The connector may also not have a water-stopping component or a water-stopping plug.

[0113] (2) In the above embodiment, the connector 1 is formed by inserting the terminal module 37 inside the outer conductor 30 housed in the housing 50. However, it is not limited to this. The connector can also be formed by inserting the shield terminal connected to the cable into the housing.
