Description

[Technical field]

[0001] The present disclosure relates to a connector and a module. [Background technology]

[0002] As manufacturing factories become more automated, sensor devices for automation are widely used. Depending on the factory, sensor devices are required to be specially designed, such as waterproof or explosion-proof. To achieve waterproof or explosion-proof specifications, a method is available in which a sealant is filled inside the sensor device. Patent Document 1 describes a potting-compatible connector that is mounted on a board inside such a sensor device. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-69096 A Summary of the Invention [Problem to be solved by the invention]

[0004] Patent Document 1 describes a connector that includes a connector housing and contact terminals, and the connector housing has a cylindrical portion on the inside of which is formed an air reservoir portion in which air generated when the potting material hardens accumulates. However, this connector is structured so that a protrusion is formed on the outer peripheral wall portion and engages with an engagement portion of the cable side connector to fit and hold the connector, and the mating cable side connector is structured so that when the connector is fitted, the mating cable side connector has an engagement portion on the outer periphery of the connector housing, so if the protrusion on the outer peripheral wall portion is buried in the potting material, the cable side connector cannot be fitted and held in the connector. Even if the protrusion is not buried in the potting material, if the potting material is injected close to the protrusion, it will interfere with the engagement portion of the cable side connector, so the cable side connector cannot be fitted and held in the connector. In addition, the cable side connector is structured so that the outer peripheral wall portion of the connector housing is disposed between the engagement portion and the side on which the engagement portion is formed, so that the cable side connector is large (thick). If the mating connector is large, a large dead space is required for the device used in the fitted and held state. For this reason, it is desirable to provide a convex engaging portion on the outer peripheral wall of the mating connector, and to have the connector accommodate the mating connector together with the engaging portion when mated. However, in such a structure, an engaging hole must be formed in the connector into which the engaging portion of the mating connector engages, and it is necessary to prevent the potting material from entering the connector through the engaging hole.

[0005] Therefore, an object of the present disclosure is to provide a connector that can prevent potting material from entering the inside of the connector through an engagement hole. [Means for solving the problem]

[0006] The connector of the present disclosure includes a housing and a terminal.

[0007] The housing includes a first portion that supports the terminal, and a second portion that is disposed on one side of the first portion in a first direction and includes a receiving portion.

[0008] The storage section is open on one side in a first direction and includes a wall portion on one side in a second direction substantially perpendicular to the first direction.

[0009] The wall portions stand in contact with each other in a first direction and include an engagement hole that penetrates in a second direction.

[0010] The housing includes a turn-back portion on the other side in the first direction of the engagement hole.

[0011] The turning portion includes a first end face facing one side in the second direction, a turning face connected to the first end face and facing the other side in the first direction, and a first wall face connected to the turning face and facing one side in the second direction. Effect of the Invention

[0012] According to the connector of the present disclosure, it is possible to prevent the potting material from entering the inside of the connector through the engagement hole. [Brief description of the drawings]

[0014] Hereinafter, embodiments of the present disclosure will be described in detail. Note that components having the same functions are given the same reference numbers and redundant description will be omitted.

[0015] For the purposes of explanation, the direction in which a connector and a mating connector are inserted and removed to maintain and release the mating is referred to as the first direction (Z direction). One side of the first direction is referred to as the Z1 side, and the other side of the first direction is referred to as the Z2 side in each drawing. Details will be described later, but the second direction (Y direction) that is approximately perpendicular to the first direction (Z direction) and the third direction (X direction) that is approximately perpendicular to both the first and second directions are also used in the explanation. One side of the second direction is referred to as the Y1 side, the other side of the second direction is referred to as the Y2 side, one side of the third direction is referred to as the X1 side, and the other side of the third direction is referred to as the X2 side in each drawing.

[0016] [First embodiment] <First technical feature> Hereinafter, a first technical feature of the connector according to the first embodiment of the present disclosure will be described with reference to FIG.

[0017] As shown in the figure, the connector C1-p of this embodiment includes a housing 1 and a terminal 2. The housing 1 includes a first portion 11 and a second portion 12. The first portion 11 supports the terminal 2. The second portion 12 is disposed on one side in the first direction of the first portion 11 (the Z1 side in the figure), and includes an accommodating portion 121.

[0018] The storage section 121 is open on one side in the first direction (Z1 side) and includes a wall section 122 on one side in the second direction (Y1 side) that is substantially perpendicular to the first direction (Z direction). Note that in the example shown in the figure, the wall sections 122 are not limited to the Y1 side, but are also included on the Y2 side, X1 side, and X2 side.

[0019] The wall portion 122 stands in contact in a first direction (Z direction) and includes an engagement hole 123 penetrating in a second direction (Y direction).

[0020] The housing 1 includes a turning portion 13 on the other side (Z2 side) of the engagement hole 123 in the first direction.

[0021] The turning portion 13 includes a first end face 131 facing one side in the second direction (Y1 side), a turning surface 132 connected to the first end face 131 and facing the other side in the first direction (Z2 side), and a first wall surface 133 connected to the turning surface 132 and facing one side in the second direction (Y1 side).

[0022] The mating connector C2-p is connected to the connector C1-p (details will be described later).

[0023] <Effects of the first technical feature> The connector C1-p is mounted on a substrate and housed together with the substrate in the internal space of a housing (not shown), and a sealant is injected into the internal space of the housing to fix the substrate and the connector C1-p. In this case, assuming a connector that does not have a switching portion 13 as shown in FIG. 2A, the following problems may occur.

[0024] 2A, the injection amount of the sealant P1 is controlled in the process so that the upper limit of the control height of the liquid surface (indicated by a downward black triangle in the figure) is lower than the engagement hole 123. However, because the sealant P1 is a sol-like fluid substance until it is cured by UV irradiation, heating, or the like, the sealant P1 creeps up the wall surface of the housing 1 due to the action of surface tension, causing a bulge p of the liquid surface.

[0025] If the liquid level is just below the engagement hole 123 of the connector, a rise p of the liquid level due to surface tension may cause the sealant P1 to enter the accommodating portion 121 through the engagement hole 123, causing the sealant P1 to adhere to the terminal 2 and resulting in poor contact with the mating connector C2-p, or the sealant P1 that has entered the accommodating portion 121 may interfere with the body 3 of the mating connector C2-p, making it impossible to insert it into the accommodating portion 121.

[0026] The height of the protrusion p varies depending on the surface condition of the housing 1, the characteristics of the sealing material P1, and the surrounding environment (temperature, humidity, etc.), so it is not easy to address this problem.

[0027] In the conventional example (FIG. 2A), to prevent this problem, the distance in the first direction (Z direction) between the upper limit of the management height of the liquid level of the sealant P1 and the engagement hole 123 must be sufficiently secured, taking into consideration the variation in the height of the protuberance p. However, if the upper limit of the management height of the liquid level of the sealant P1 is made too low, electronic components mounted on the board may be exposed instead of being buried in the sealant P1. On the other hand, if the dimension of the connector in the first direction (Z direction) is increased, it becomes unnecessary to lower the upper limit of the management height of the liquid level of the sealant P1, but if the dimension of the connector in the first direction (Z direction) is increased, the housing will also become larger, resulting in a larger overall device.

[0028] 2B, if the upper limit of the control height of the liquid level of the sealant P1 is set on the Z2 side of the turning surface 132, the bulge p occurs on the first wall surface 133 and the turning surface 132. This is because the turning surface 13 makes it possible to lengthen the creeping distance from the liquid level of the sealant P1 to the engagement hole 123.

[0029] This prevents the bulge p from occurring near the engagement hole 123 (first end surface 131), so there is no need to lower the upper control limit height of the liquid level or to enlarge the connector C1-p in the Z direction to take into account variations in the height of the bulge p.

[0030] <Second technical feature> A second technical feature of the connector of the first embodiment of the present disclosure will be described with continued reference to Fig. 1. As shown in the figure, the engagement hole 123 includes an engagement hole first end 123a on one side (X1 side) in a third direction substantially perpendicular to the first direction (Z direction) and the second direction (Y direction), and includes an engagement hole second end 123b on the other side (X2 side) in the third direction.

[0031] The cut-back surface 132 includes a cut-back surface first end 132a on one side in the third direction (X1 side) and a cut-back surface second end 132b on the other side in the third direction (X2).

[0032] The first end 132a of the cut-back surface is positioned on one side in the third direction (X1 side) of the engagement hole first end 123a, and the second end 132b of the cut-back surface is positioned on the other side in the third direction (X2 side) of the engagement hole second end 123b.

[0033] In the example shown in the figure, there is only one engagement hole 123, but the same applies when there are multiple engagement holes 123. Each of the multiple engagement holes 123 has an engagement hole first end 123a, and a cut-back surface first end 132a is disposed on one side in the third direction (X1 side) of any of the engagement hole first ends 123a. Similarly, each of the multiple engagement holes 123 has an engagement hole second end 123b, and a cut-back surface second end 132b is disposed on the other side in the third direction (X2 side) of any of the engagement hole second ends 123b.

[0034] <Effects of the second technical feature> The cut-back surface 132 (regardless of whether there is a single engagement hole 123 or multiple engagement holes 123) includes a cut-back surface first end 132a that is located further on the X1 side than the end closest to the X1 side of the engagement hole 123, and includes a cut-back surface second end 132b that is located further on the X2 side than the end closest to the X2 side of the engagement hole 123. This makes the creeping distance from the liquid surface of the sealing material P1 to the engagement hole 123 longer than in a connector that does not have this feature, so that the bulge p generated in an area without the cut-back portion 13 can be prevented from flowing around to the first end surface 131 side and entering the engagement hole 123.

[0035] [Second embodiment] <Third technical feature> A third technical feature of the connector of the second embodiment of the present disclosure will be described below with reference to Fig. 3. As shown in Fig. 3, the first end surface 131 of the connector C1-p-2 of this embodiment is located (protrudes) on one side in the second direction (Y1 side) from the engagement hole 123, and the housing 1 includes a protrusion 14 extending from the turning portion 13 to one side in the first direction (Z1 side) on one side in the third direction (X1 side) from the engagement hole first end 123a and on the other side in the third direction (X2 side) from the engagement hole second end 123b.

[0036] The other components are the same as those of the connector C1-p of the first embodiment.

[0037] <Effects of the third technical feature> By disposing (protruding) the first end surface 131 of the cut-back portion 13 on one side in the second direction (Y1 side) from the engagement hole 123, it is possible to further increase the creeping distance from the liquid surface of the sealant P1 to the engagement hole 123. In addition, by including the protrusion 14, it is possible to prevent the sealant P1 from reaching the engagement hole 123 even if the sealant P1 climbs over the cut-back surface 132 from the cut-back surface first end 132a or the cut-back surface second end 132b.

[0038] Furthermore, the shape of the present embodiment, including the first end surface 131, the protrusion 14, and the engagement hole 123, can be molded by integral molding using the same core in the Y direction of an injection molding die, and therefore has the advantage of being easy to manufacture.

[0039] <Fourth Technical Feature> A fourth technical feature of the connectors C1-p and C1-p-2 according to the first and second embodiments of the present disclosure will be described with reference to Figures 1 and 3. As shown in the figures, the terminal 2 includes a main body portion 21, a connection portion 22, and a tip portion 23.

[0040] The main body 21 is held by the first part 11. The connection part 22 is located on the other side in the first direction (Z2 side) of the main body 21, and is electrically connected to an electrode formed on a substrate arranged on the other side in the first direction (Z2 side) of the housing 1. The tip part 23 is located on the one side in the first direction (Z1) of the main body 21, and a part of it is arranged inside the accommodation part 121.

[0041] <Effects of the fourth technical feature> The connectors C1-p, C1-p-2 are vertical connectors in which the accommodating portion 121 of the housing 1 opens on the Z1 side and is mounted on the first surface B1a of the board B1. Therefore, the mating connector C2-p can be inserted from the Z1 side and engaged and held in place. Therefore, even if sealing material P1 is injected around the connectors C1-p, C1-p-2, as long as the sealing material P1 does not enter the accommodating portion 121, the engagement and holding of the connectors C1-p, C1-p-2 and the mating connector C2-p is not hindered.

[0042] <Fifth Technical Feature> A fifth technical feature of the connectors C1-p and C1-p-2 of the first and second embodiments of the present disclosure will be described with reference to Figures 1 and 3. The accommodating portion 121 accommodates and holds at least a part of the mating connector C2-p in a mated state with the mating connector C2-p, and the engaging hole 123 engages with the engaging portion 31 of the mating connector C2-p in a mated state with the mating connector C2-p.

[0043] <Effects of the fifth technical feature> For example, assuming a conventional example (e.g., Patent Document 1) in which the mating connector fits over the connector, the conventional connector includes an engaging protrusion on the outer periphery of the housing, and the conventional mating connector has a locking portion formed on the body that is positioned on the outside of the housing when engaged and held in place with the conventional connector.

[0044] In this case, there is a possibility that the locking part will be interfered with by the sealant if the sealant is injected into the location where the locking part is located, making it impossible to fit the parts together. Alternatively, it is necessary to lower the upper limit of the sealant level or to increase the Z-direction dimension of the connector so that the sealant level does not interfere with the locking part.

[0045] According to a fifth technical feature of the connectors C1-p, C1-p-2, the engagement hole 123 engages with the engagement portion 31 of the body 3 of the mating connector C2-p, thereby making it possible to maintain the mated state between the connector C1-p (C1-p-2) and the mating connector C2-p, thereby eliminating the problems associated with a shape in which the mating connector fits over the connector.

[0046] <Sixth Technical Feature> Hereinafter, a sixth technical feature of the module including the connectors C1-p and C1-p-2 according to the first and second embodiments of the present disclosure will be described with reference to Fig. 2B. The module of the present disclosure includes a housing (not shown), a connector C1-p (C1-p-2), a substrate B1, and a sealing material P1.

[0047] The housing accommodates the connector C1-p of the first embodiment or the connector C1-p-2 of the second embodiment and the board B1 in its internal space.

[0048] As shown in FIG. 2B, the sealing material P1 is injected into the internal space of the housing, and its liquid level (the downward-facing black triangle in the figure) is on one side in the first direction (Z1 side) of the substrate B1 and on the other side in the first direction (Z2 side) of the cut-back surface 132.

[0049] Note that FIG. 2B is a diagram showing the characteristics of the connector C1-p of the first embodiment, but the positional relationship between the substrate B1, the cut-back surface 132, and the liquid surface of the sealing material P1 is the same in the connector C1-p-2 of the second embodiment.

[0050] <Effects of the sixth technical feature> The module including the connector C1-p (C1-p-2) can be made waterproof or explosion-proof by using the sealing material P1. If the module is explosion-proof, the connector C1-p (C1-p-2) can be electrically connected to an external device by a harness (an example of a mating connector). For example, if the external device is a power supply unit, by making the power supply unit explosion-proof as well, it is possible to replace the power supply unit while the module is installed in an explosion-proof area.

[0051] The components of the above-described embodiments can be combined with each other as long as they are not inconsistent with each other. The materials, shapes, dimensions, numbers, and arrangements of the components in each aspect of the above-described embodiments are merely examples, and can be modified in any way as long as the same functions can be realized. EXAMPLES

[0052] Hereinafter, a connector, a module, and a mating connector according to Example 1, which is a detailed design example of the connector, the module, and the mating connector of the above-mentioned embodiment, will be described with reference to FIGS.

[0053] As shown in FIGS. 4 and 5, the module of this embodiment is a device that includes a housing K1, a sealing material P1, and a connector C1, and is connected to a mating connector C2.

[0054] The housing K1 can be made of an insulating material and includes an internal space K11 as shown in Fig. 6. The internal space K11 accommodates the board B1 and the connector C1. As shown in Fig. 4, the internal space K11 is filled with a sealing material P1.

[0055] 6 and 7, the connector C1 is mounted on the board B1 in a first direction (Z direction) and used. In this embodiment, the connector C1 is disposed on one side (Z1 side) of the board B1 in the first direction.

[0056] The board B1 includes a board first surface B1a, which is a surface on one side in the first direction (Z1 side), a board second surface B1b, which is a surface on the other side in the first direction (Z2 side), and an electrode B1c. The connector C1 is mounted and disposed on the board first surface B1a. When the connection portion of the terminal 2 of the connector C1 has a straight terminal shape, the electrode B1c is a through-hole electrode that penetrates the board first surface B1a and the board second surface B1b and is electrically connected, and when the connection portion of the terminal 2 of the connector C1 has a surface mounting shape, the electrode B1c is a surface electrode formed on the board first surface B1a. The board B1 is a two-layer board composed of two layers, the board first surface B1a and the board second surface B1b, but may be a multi-layer board of three or more layers, and may be, for example, a rigid board or a flexible board.

[0057] As shown in FIGS. 8 and 9, the connector C1 includes a housing 1 and at least one terminal 2 (two terminals 2 in this embodiment).

[0058] The housing 1 is formed of an insulating material and includes a first portion 11 and a second portion 12. The first portion 11 supports the terminal 2. The second portion 12 is disposed on the Z1 side of the first portion 11 and includes an accommodating portion 121, which includes a wall portion 122. The accommodating portion 121 is open on the Z1 side. The wall portion 122 stands in contact with the first direction (Z direction). As shown in the figure, the accommodating portion 121 may be substantially in the shape of a rectangular prism (substantially a rectangular parallelepiped).

[0059] The storage section 121 is not necessarily limited to a substantially square prism (substantially rectangular parallelepiped) shape, and may be any shape. Therefore, the wall section 122 may be walls on four sides, or may be cylindrical if the storage section 121 is cylindrical. The wall section 122 may also be configured by a combination of other shapes.

[0060] The wall portion 122 on one side in the second direction (Y1 side) includes at least one engagement hole 123 (two engagement holes 123 in this embodiment) penetrating in the second direction (Y direction).

[0061] Furthermore, the housing 1 includes a turned-back portion 13 on the Z2 side of the engagement hole 123. The turned-back portion 13 includes a first end face 131 facing one side in the second direction (Y1 side), a turned-back surface 132 connected to the first end face 131 and facing the other side in the first direction (Z2 side), and a first wall surface 133 connected to the turned-back surface 132 and facing one side in the second direction (Y1).

[0062] The engagement hole 123 may include an engagement hole first end 123a on the X1 side and an engagement hole second end 123b on the X2 side, and the cut-off surface 132 may include a cut-off surface first end 132a on the X1 side and a cut-off surface second end 132b on the X2 side, and the cut-off surface first end 132a may be located on the X1 side of all of the engagement hole first ends 123a, and the cut-off surface second ends 132b may be located on the X2 side of all of the engagement hole second ends 123b.

[0063] Furthermore, the first end surface 131 may be located (protrude) toward the Y1 side from the engagement hole 123, so that a cut-back portion upper surface 134 may be formed on the side opposite to the cut-back surface 132.

[0064] The housing 1 may also include a convex portion 14 extending from the turning portion 13 to one side in the first direction (Z1 side) on one side in the third direction (X1 side) from the first end 123a of the engagement hole and to the other side in the third direction (X2 side) from the second end 123b of the engagement hole.

[0065] The protrusion 14 on the X1 side may be disposed on the X1 side of the engagement hole first ends 123a of all of the engagement holes 123, and the protrusion 14 on the X2 side may be disposed on the X2 side of the engagement hole second ends 123b of all of the engagement holes 123. The protrusion 14 may include a protrusion first end 141 on the Z1 side, and the protrusion first end 141 may be disposed on the Z1 side of the engagement hole 123.

[0066] The protrusion 14 may include a protrusion second end 142 on the Y1 side, and the protrusion second end 142 may be at the same position as the first end surface 131 in the second direction (Y direction).

[0067] As shown in Figs. 10B and 10C, the protrusion 14 and the cut-back portion upper surface 134 may be omitted.

[0068] The first end surface 131 may be a surface parallel to the ZX plane or may be inclined. The turning surface 132 may be a surface parallel to the XY plane or may be inclined. The first wall surface 133 may be a surface parallel to the ZX plane or may be inclined. The turning portion upper surface 134 may be a surface parallel to the XY plane or may be inclined.

[0069] 8 and 9, the terminal 2 is formed of a conductive material such as a metal plate, and includes a main body 21, a connection portion 22, and a tip portion 23. The main body 21 may be held by the first portion 11 of the housing 1. The connection portion 22 extends from the main body 21 to the Z2 side, and can be electrically connected to an electrode formed on the substrate B1 arranged on the Z2 side of the housing 1. The tip portion 23 extends from the main body 21 to the Z1 side, and can be structured so that a portion of the tip portion 23 is arranged within the accommodation portion 121 of the housing 1.

[0070] When there are two or more terminals 2, the terminals 2 can be arranged spaced apart from each other in the second direction (Y direction) and / or the third direction (X direction). In addition, the creepage distance of the housing 1 between adjacent terminals 2 can be made sufficiently long to arrange them at a distance that satisfies the explosion-proof specifications.

[0071] The connection portion 22 of the terminal 2 may be in the form of a straight terminal extending to the Z2 side, or in the form of a surface mount terminal extending to the Z2 side with its tip extending in the second direction (Y direction) or the third direction (X direction).

[0072] As shown in FIGS. 11 and 12, the mating connector C2 may include a body 3, at least one contact 4, and an electric wire 5.

[0073] The body 3 is made of an insulating material and may include an engagement portion 31 protruding toward the Y1 side. The contact 4 is made of a conductive material such as a metal plate, and may be electrically connected to the electric wire 5 and at least a portion of the contact 4 may be housed and held in the body 3.

[0074] When mating connector C2 is mated with connector C1, at least a part of body 3 may be accommodated and held in accommodation portion 121 of housing 1, and engaging portion 31 may be engaged with engaging hole 123 to maintain mating state with connector C1. Engaging portion 31 may have a half-lock shape or a full-lock shape. Note that in the figure, a half-lock shape having tapers on both Z1 and Z2 sides is shown.

[0075] The number of contacts 4 may be the same as or less than the number of terminals 2, and may be structured to be electrically connected to an external device via electric wires 5. For example, if the external device is a power supply unit having a battery, and a sensor unit is mounted on the board B1, the connector C1 is a two-pole connector with two terminals, and by fitting and holding it with the mating connector C2, it becomes possible to supply power from the power supply unit to the sensor unit on the board B1.

[0076] <Method of assembling the connector and sealing the inside of the housing> 8, the terminal 2 is inserted from the Z2 side of the first part 11 of the housing 1, and the main body 21 of the terminal 2 is press-fitted and fixed. At this time, the connection part 22 of the terminal 2 is exposed on the Z2 side of the housing 1, and the tip part 23 is accommodated in the accommodation part 121 of the housing 1 and exposed.

[0077] 6, the connector C1 is mounted on the first surface B1a of the board B1 by soldering or the like, and at least one terminal 2 of the connector C1 is electrically connected to the electrode B1c. Next, the housing K1 is fixed in a position in which the internal space K11 opens in the Z1 direction, and the board B1 on which the connector C1 is mounted is placed at a predetermined position in the internal space K11 of the housing K1.
