Description

[Technical field]

[0001] The present invention relates to a connector, and more particularly to a connector for connecting to a computer board or the like. [Background technology]

[0002] For example, Patent Document 1 discloses an electrical connector for use in an electronic control unit (ECU). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-47432 A Summary of the Invention [Problem to be solved by the invention]

[0004] The inventors of the present application realized that conventional electrical connectors have problems to be overcome and found it necessary to take measures to address these problems. Specifically, the inventors of the present application found the following problems:

[0005] For example, as shown in Fig. 11, a conventional connector 100 disclosed in Patent Document 1 and the like can be electrically connected to a board 200 included in an electronic control unit (ECU) or the like (see Fig. 11(A)). The conventional connector 100 generally has a connector body 101 and a wall portion 102 integrally formed on the surface thereof (see Fig. 11(B)). The conventional connector 100 can be coupled to another connector by arranging it in the direction indicated by X1 in Fig. 11(B), for example, and the board 200 can be arranged in the direction indicated by X2.

[0006] Wall portion 102 provided on connector body 101 is disposed so as to entirely surround connector body 101. Wall portion 102 of connector body 101 can seal or cap housing 300 by being positioned, for example, inside an opening of housing 300 for accommodating and protecting substrate 200 (see FIG. 12(A)). A conventional connector 100 has a plurality of terminals (or contacts) 103 arranged to penetrate a connector body 101 (see Figs. 11 and 12). The terminal 103 has two ends 103a and 103b (see Fig. 12(A)). The end 103a is referred to as a first end, and the end 103b is referred to as a second end. The first end 103a can be electrically connected to another terminal provided inside another connector 400 (see Figs. 12(B) and 12(C)). The second end 103b can be electrically connected to an electronic circuit of a substrate 200 via solder 150 or the like (see Fig. 12(A)).

[0007] The conventional connector 100 can be mated with another connector 400 to form an electrical connection between the two connectors (100, 400) (see Figures 12(B) and 12(C)).

[0008] Connector 400 has wiring 500 called a harness attached, and when connector 400 is attached to conventional connector 100, harness 500 may swing wildly as shown by the arrow in Fig. 12(B) (hereinafter referred to as "shaking"). After connector 400 is attached to connector 100, harness 500 may swing wildly or vibrate finely as shown by the arrow in Fig. 12(C) (hereinafter referred to as "vibration").

[0009] When such "agitation" or "vibration" occurs, stress is applied to terminal 103 provided on connector 100, and cracks may appear in the connection between terminal 103 and board 200, specifically solder 150, which may damage the bond between terminal 103 and board 200 and cause poor contact.

[0010] Such "jitter" or "vibration" may occur not only in the up-down direction shown in Fig. 12, but also in the left-right direction. If such "jitter" or "vibration" generates a force in the left direction as shown by the arrow in Fig. 13(A), for example, connector 100, particularly wall 102, may tilt inside opening 301 of housing 300 (see Fig. 13(B)). Such tilting also puts stress on the terminals, and there is a risk that the connection between the terminals and the board, specifically the solder, may crack, damaging the bond between the terminals and the board and causing poor contact.

[0011] The present invention has been made in view of the above problems. That is, a main object of the present invention is to provide a connector that can further reduce stress caused by "agitation" and "vibration."

[0012] Furthermore, in conventional connectors 100, there is a risk that fluids such as water droplets may seep in between wall 102 of connector body 101 and opening 301 of housing 300, causing poor contact of the board, as shown by the arrow in Fig. 14. For this reason, a secondary object of the present invention is to provide a connector that can further suppress the intrusion of fluids. [Means for solving the problem]

[0013] The present inventors attempted to solve the above problems by taking a new approach rather than simply extending the conventional technology, and as a result, they came up with the invention of a connector that achieves the above-mentioned main object.

[0014] For example, as shown in Fig. 1, by arranging multiple protrusions 2 protruding outward from the surface of connector body 1 in a direction crossing terminal 3 (for example, in the Y-axis direction and / or Z-axis direction shown in Fig. 1(C)) and positioning such protrusions 2 inside the opening of housing 30 for accommodating a board (see Figs. 2 and 3), it has been found that even if the connector body is subjected to external force due to "shaking" or "vibration," the force can be dispersed and released by such multiple protrusions 2, thereby further reducing the stress on terminal 3. It has also been found that the intrusion of fluids such as water droplets can be further suppressed by providing such multiple protrusions 2.

[0015] According to the present invention, there is provided a connector including a terminal, the connector comprising: the terminal has a first end for electrically connecting to another terminal and a second end for connecting to a substrate; the connector has a plurality of protrusions provided to face an opening of a housing for accommodating the board and to be positioned within the opening; The plurality of protrusions each protrude outward from the surface of the connector body and are arranged in a direction transverse to the terminal. Effect of the Invention

[0016] The present invention provides a connector that can reduce stress caused by "agitation" and "vibration" and further suppresses the intrusion of fluids. Note that the effects described in this specification are merely examples and are not limiting, and additional effects may also be provided. [Brief description of the drawings]

[0018] The present disclosure relates to a connector that can be used for electrical connections. More specifically, the present disclosure relates to a connector (10) that includes a terminal (3) (see FIG. 1). In the connector (10) of the present disclosure, the terminal (3) has a first end (3a) for electrically connecting to another terminal (not shown) and a second end (3b) for connecting to the substrate (20) (see Figures 1(A) and 1(B)). The connector (10) of the present disclosure has a plurality of protrusions (2) arranged to face an opening of a housing (30) for accommodating a substrate (20) and to be positioned inside the opening (see Figures 1 and 2). Such multiple protrusions (2) each protrude outward from the surface of the connector body (1) and are arranged in a direction transverse to the terminals (3) (for example, in the Y-axis direction and / or Z-axis direction shown in Figure 1 (C)).

[0019] The terms used in this disclosure will be explained.

[0020] (connector) "Connector" means a part or member that includes at least one terminal and can be electrically connected to another connector. The connector has a connector body. There is no particular limitation on the shape of the connector body. The connector body is preferably box-shaped (see FIG. 1). The cross-sectional shape of the connector body is preferably rectangular, such as a square. The corners of the connector body may be rounded. The connector body has two end faces (or edges) (1a, 1b). One end face (1a) of the connector body can be physically coupled (e.g., engaged and / or mated) with another connector. The other end face (1b) of the connector body can be physically coupled (e.g., engaged and / or mated) with another structure. Examples of other structures include, but are not limited to, enclosures or housings for computers, such as electronic control units (ECUs), more specifically, electronic control units for vehicles. It is preferable that the two end faces (1a, 1b) of the connector body are positioned opposite each other, specifically, in a parallel relationship.

[0021] An end face of the connector main body that can be joined with another connector preferably has a fitting portion for accommodating at least a part of the other connector (see FIG. 1(C)). The end faces that can mate with other structures in the connector body may or may not have mating portions. The connector body can secure at least one terminal that protrudes through an end face (eg, end face 1b) of the connector (see Figures 1(A) and 1(B)).

[0022] The connector of the present disclosure is characterized by having "multiple protrusions" protruding outward from the surface of the connector body. The multiple protrusions are preferably arranged in a direction (e.g., the Y-axis direction and / or the Z-axis direction shown in FIG. 1(C)) that crosses a terminal (e.g., terminal 3 shown in FIG. 1) described below. Here, the direction that crosses the terminal includes, but is not limited to, a direction perpendicular to the longitudinal axis of the terminal as in the illustrated embodiment.

[0023] The number of convex portions is not particularly limited, and is 2 or more, for example, 2 or more and 50 or less, and in a more specific example, 2 or more and 20 or less.

[0024] The connector of the present disclosure has multiple protrusions, and thus can disperse and release the force even when the connector body is subjected to external force due to "shaking" or "vibration." Furthermore, by providing multiple protrusions 2, the intrusion of fluids such as water droplets can be further suppressed. The effect of multiple protrusions will be described in the specific embodiment described below.

[0025] It is preferable that the plurality of protrusions are aligned on the surface of the connector body. It is more preferable that the plurality of protrusions are aligned in a straight line (see FIG. 1(A) and FIGS. 2(A) and 2(B)). "Multiple convex portions are aligned in a straight line" means that at least two of the multiple convex portions are arranged on the same line on one face of the connector body, and two or more convex portions may be arranged on the same line on each face around the entire circumference of the connector body. The straight line along which the multiple protrusions are aligned is preferably a straight line along a direction that crosses the terminal described below (for example, the Y-axis direction and / or the Z-axis direction in FIG. 1(C)). By aligning multiple protrusions in a straight line, even if the connector body is subjected to external forces such as shaking or vibration, the force can be better dispersed and dissipated.

[0026] It is preferable that a plurality of protrusions are arranged over the entire circumference of the connector body (see FIG. 2(B)). In the present disclosure, the arrangement of multiple protrusions "all around" the connector body means that multiple protrusions surround the connector body along a direction crossing the terminals (e.g., the Y-axis direction and / or the Z-axis direction in FIG. 1(C)) described below. There is no particular limit to the number of protrusions surrounding the connector body. By arranging multiple protrusions around the entire circumference of the connector body, the force can be better dispersed and dissipated even when the connector body is subjected to external force due to "jerking" or "vibration."

[0027] The multiple protrusions are preferably arranged at a distance. The distance may be called the "pitch" and means the distance between two protrusions. The pitch may be equal or irregular (random). For example, the pitches P1 and P2 shown in FIG. 3(B) may be the same or different. For example, it is preferable that the multiple protrusions are arranged at an equal pitch. In one example, by arranging the multiple protrusions at an equal pitch, even if the connector body receives an external force due to "jerking" or "vibration," the force can be more uniformly dispersed and released. In another example, when the vector of the external force of "jerking" or "vibration" received by the connector body is predetermined or specific, for example, an arrangement other than an equal pitch is preferable in order to set the pitch to counter the specific vector.

[0028] The main body of the protrusion preferably has a "plate-like" shape (see Figs. 1 and 2). In the present disclosure, "plate-like" means a shape in which two main surfaces are positioned opposite each other (see Fig. 8(A)). However, it is not limited to the shape shown in the figures in which the two main surfaces are positioned parallel to each other and opposite each other. The two main surfaces are preferably arranged along a direction crossing the terminal described below (for example, the Y-axis direction and / or the Z-axis direction in FIG. 1(C)). Since at least the main body of the protrusion is plate-shaped, even if the connector main body is subjected to external force due to "jitter" or "vibration," the force can be dispersed and released more effectively.

[0029] There is no particular limitation on the shape of the main surface of the protrusion. The main surface of the protrusion preferably has a substantially rectangular shape. In the present disclosure, the term "substantially rectangular" refers to shapes such as quadrilaterals such as squares and rectangles, trapezoids, rhombuses, and parallelograms (see FIG. 6 and FIG. 8(A)).

[0030] The protrusions preferably have a rectangular cross-sectional shape. The term "rectangular cross-sectional shape" refers to a cross-sectional shape having a substantially rectangular shape such as a quadrilateral such as a square or a rectangle, a trapezoid, a rhombus, or a parallelogram. Such a cross section may be a cross section perpendicular to the main surface of the protrusion, or a cross section parallel to the main surface of the protrusion. It is preferable that the cross section perpendicular to the main surface of the protrusion and the cross section parallel to the main surface of the protrusion both have a substantially rectangular shape. The protrusion preferably has, for example, a plate-like box shape as a whole. Such a plate-like protrusion may be flexibly and elastically deformed when subjected to an external force. By having the protrusion have a generally rectangular cross-sectional shape, even if the connector body is subjected to external force due to "jitter" or "vibration," the force can be more evenly distributed and dissipated.

[0031] The connector body and the convex portion may be manufactured integrally or separately from materials such as resin by a conventionally known manufacturing method. The connector body and the convex portion may be manufactured by molding. Only the convex portion may be attached externally. There is no particular limitation on the resin that constitutes the connector body and the convex portion. The resin used in the connector body and the convex portion may be the same or different.

[0032] (Terminal) A "terminal" refers to a part or member that has the property of conducting electricity, in other words, is conductive, and can be electrically connected to a terminal contained in another connector (hereinafter sometimes referred to as "another terminal"). There is no particular limitation on the shape of the terminal, but it is preferable that the terminal has a linear, elongated shape such as a rod shape or a plate shape. The terminal has two ends. One end can be electrically connected to another terminal (hereinafter referred to as the "first end") (see "first end 3a" in FIG. 1(B)). The other end can be electrically connected to a board included in, for example, a computer (hereinafter referred to as the "second end") (see "second end 3b" in FIG. 1(A)). The terminal is preferably made of a conductor. Examples of the conductor include metals and / or alloys. Examples of metal elements that can be contained in the metals and / or alloys include copper (Cu), aluminum (Al), iron (Fe), zinc (Zn), and the like. It is preferable to use at least one selected from the group consisting of copper, aluminum, stainless steel, and brass (sometimes called brass or brass) as the conductor. When the terminal is made of a material such as a metal and / or an alloy, it may further have a plating layer or a surface treatment layer, which preferably contains an element such as chromium or nickel. The terminal is preferably inserted by press-fitting through at least one through-hole provided in the connector body and fixed to the connector body. It is preferred that at least one (but no more than 100) of the terminals be secured to the connector body.

[0033] (other connectors) "Another connector" means a part or member that can be at least electrically connected to the connector of the present disclosure. The other connector includes at least one terminal (but not more than 100) that corresponds to the terminal included in the connector of the present disclosure (hereinafter referred to as the "other terminal"). The other connector may be a conventionally known commercially available connector, for example, a connector 400 having a harness 500 attached thereto as shown in Fig. 12(B) may be used as the other connector. The harness may be a bundle of wires, each of which may be electrically connected to a different terminal. Another connector may be used to connect to a computer. There is no particular limitation on the shape of the other connector. The other connector may have a complementary shape that can fit into the connector of the present disclosure. In other words, the connector of the present disclosure may have a complementary shape that can fit into the shape of the other connector. Specifically, the connector of the present disclosure and the other connector may have shapes that allow them to fit together with each other.

[0034] (other terminals) The "other terminal" is a part or member that can be electrically connected to the terminal included in the connector of the present disclosure. For example, if the terminal included in the connector of the present disclosure is a male terminal, the other terminal may be a female terminal. The other terminal may be a commercially available terminal that is publicly known in the art, without any particular restrictions.

[0035] (substrate) "Substrate" means a plate-shaped part or member having an electronic circuit or a plate-shaped part or member capable of forming an electronic circuit. The substrate is preferably a printed circuit board that can be used in a computer or the like. An electronic circuit formed on the board can be electrically connected to the connector of the present disclosure via the terminals. The electrical connection between the board and the terminals can be by soldering as in the conventional case (see FIG. 12). The substrate preferably has a substantially rectangular shape, including a quadrilateral such as a square or a rectangle, when viewed from above.

[0036] (computer) The term "computer" refers to a computing device or apparatus having electronic circuits formed on a substrate. The electronic circuits may include semiconductor elements such as transistors and capacitors. Examples of computers include electronic control units (ECUs), more specifically, in-vehicle electronic control units. Examples of in-vehicle electronic control units include calculation devices for controlling engines and / or motors. Computers generally have a housing for housing a board on which an electronic circuit is formed.

[0037] (Housing) The "casing" is a part or member capable of accommodating a substrate and protecting the accommodated substrate and the electronic circuit formed thereon, and may also be called a housing or case (see FIG. 1(C)). The casing preferably has a box-like shape with a cross section that is substantially rectangular, including quadrilaterals such as a square or rectangle. The housing has an opening for disposing and / or positioning the connector of the present disclosure, and can accommodate a board in the space inside the housing body. From this perspective, the connector of the present disclosure can be said to be a part or member that can function as a cap. The housing may be made of metal or resin, but is preferably made of metal from the viewpoint of heat dissipation. The housing may have a two-part configuration, for example, a cup-shaped member and a lid-shaped member. Both the cup-shaped member and the lid-shaped member may be made of metal. Either the cup-shaped member or the lid-shaped member, preferably the cup-shaped member, may be made of metal. In this case, the lid-shaped member may be made of resin.

[0038] The term "cup-shaped member" refers to a member having a side portion corresponding to a body portion and a main surface portion (in a typical embodiment, for example, the top surface) that is continuous with the side portion, and in which a hollow portion can be formed inside. The cup-shaped member preferably has a substantially rectangular shape, including a quadrangle such as a square or a rectangle, when viewed from above. The term "lid-like member" refers to a member that can be provided to cover the cup-like member. The lid-like member may be, for example, a single member (typically a flat member) that extends in the same plane. It is preferable that the lid-like member has a substantially rectangular shape, including a quadrangle such as a square or a rectangle, in top view, corresponding to the cup-like member. It is preferable that the cup-shaped member and the lid-shaped member are coupled to each other by engaging or fitting to form the housing (see Fig. 1(C) and Fig. 2). The cup-shaped member and the lid-shaped member may be coupled to each other by fastening using screws or the like.

[0039] The "opening" of the housing means a part (e.g., a wall portion, etc.) constituting a space or opening provided for arranging and / or positioning the connector of the present disclosure in the housing, and means a part (e.g., a wall portion, etc.) of the housing that can receive or accommodate at least some of the multiple protrusions provided on the connector body (see FIG. 2). Such an "opening" may also be called a "receiving portion," "accommodating portion," or "fitting portion." The opening is preferably provided so as to face the connector of the present disclosure. The opening may be provided, for example, on a side surface of the housing other than the main surface. Here, the main surface of the housing means the surface having the largest area, for example, the top surface and / or bottom surface of the housing.

[0040] The opening has an opening through which a part of the connector body can pass. There are no particular limitations on the shape and dimensions of the opening, and it is preferable that the opening has a shape and dimensions that are approximately complementary to the shape of the connector body (see FIG. 1(C) and FIGS. 2(A) and (B)).

[0041] The opening of the housing may have a plurality of recesses (for example, recesses 32 shown in schematic cross section from above in FIG. 3(A)) for receiving a plurality of protrusions provided on the connector body.

[0042] The number of recesses is not particularly limited, and is 2 or more, for example, 2 or more and 50 or less, more specifically, 2 or more and 20 or less.

[0043] It is preferable that the recess provided in the opening of the housing has a shape that is complementary to the shape of the protrusion provided in the connector body (see Figs. 3(A) and 5(A)). In this disclosure, "complementary shape" means a similar shape with different dimensions, and may be a shape similar to the convex portion of the connector as long as it can receive at least a portion of the convex portion of the connector, and does not have to be exactly the same shape.

[0044] The recess preferably has a rectangular cross-sectional shape. The rectangular cross-sectional shape may be, for example, a quadrilateral such as a square or a rectangle, or a substantially rectangular shape such as a trapezoid, a rhombus, or a parallelogram (see FIG. 3(A) and FIG. 5(A)).

[0045] By providing multiple recesses at the opening of the housing, even if the connector body is subjected to external force due to "jitter" or "vibration," the force can be more dispersed and dissipated by the protrusions provided on the connector body.

[0046] There may be a space (S) formed by separation (or spacing) between the recess provided at the opening of the housing and the protrusion provided on the connector body (see Figures 3(B) and 5(B)).

[0047] By providing the space (S), even if the connector body is subjected to external force due to "jitter" or "vibration," the force can be mitigated by the convex portion provided on the connector body, and the force can be more dispersed and released.

[0048] In this disclosure, "shaking" means swinging at least once. More specifically, it means swinging of the connector that may occur when the harness of another connector attached to the connector of the present disclosure swings or ripples. "Shaking" may occur, for example, when connecting another connector to the connector of the present disclosure on an assembly line during manufacturing. It may also occur when the connector of the present disclosure is used, for example, when it is mounted on a vehicle or during maintenance.

[0049] In the present disclosure, "vibration" means periodic or non-periodic shaking. More specifically, it means shaking that may occur due to small vibrations of a harness of another connector attached to the connector of the present disclosure. For example, "vibration" may occur when connecting another connector to the connector of the present disclosure on an assembly line during manufacturing. It may also occur when the connector of the present disclosure is used, for example, when it is mounted on a vehicle or during maintenance.

[0050] Such "agitation" and "vibration" include not only vertical and horizontal shaking, but also shaking in any direction. In addition, in this disclosure, "agitation" and "vibration" may be collectively referred to simply as "shaking."

[0051] Even if the connector of the present disclosure is subjected to an external force due to such "shaking," the force can be dispersed and released by the multiple protrusions provided on the connector body. This in turn reduces the stress on the terminals provided on the connector body. As a result, the connection between the terminals and the board, more specifically the connection by solder, can be protected, and undesirable contact failures can be avoided.

[0052] The space (S) (see Fig. 3(B) and Fig. 5(B)) provided between the recess provided at the opening of the housing and the protrusion provided on the connector body can retain fluids such as water droplets in the space (S) by, for example, capillary action and / or surface tension. In turn, it is possible to prevent fluids from penetrating into the housing at a more forward position. As a result, it is possible to prevent corrosion of the terminals and the board due to fluids such as water droplets, and to avoid undesirable contact failures.

[0053] In the present disclosure, the term "fluid" refers to a fluid such as water, alcohol, oil, etc., and may contain various additives. The fluid may be a liquid or a particulate material such as water droplets or water vapor. The fluid may be water droplets or water vapor for cleaning. The invention of the present disclosure can provide remarkable drip-proof performance against such fluids.

[0054] The distance between the recessed portion provided at the opening of the housing and the protruding portion provided on the connector body (for example, d1 to d9 shown in FIG. 3(B) and d 10 ~d 18 and D2 and D4 shown in FIG. 7(B)) is preferably smaller than the distance between the housing and the connector body (eg, D5 shown in FIG. 7(B)). With such a configuration, for example by capillary action and / or surface tension, fluids such as water droplets can be retained in the space between the recess provided in the opening of the housing and the protrusion provided in the connector body (for example, space S shown in Figures 3 to 6 and space S1 shown in Figure 7), and the intrusion of fluids into the space provided between the housing and the connector body (for example, S2 shown in Figure 7) can be prevented.

[0055] Furthermore, the convex portion formed on the connector body may have at least one selected from the group consisting of a passage for retaining fluids such as water droplets (e.g., passage 50 provided at the bottom of the convex portion as shown in Figure 8 (B)), a groove (or notch), a hole (or recess), and a hole (or through hole). By providing such passages, grooves, holes and / or apertures in the protrusions, fluids such as water droplets can be further retained, which can further prevent the fluids from penetrating into the housing. Such passages, grooves, holes and / or pores can be formed in any location or area of ​​the protrusion. They may be provided on the main surface and / or the upper surface and / or the side surface and / or the lower surface of the protrusion. In addition, from the viewpoint of retaining such fluids, the protrusion may be made of a porous material.

[0056] The connector of the present disclosure has the above-mentioned configuration, and thus can retain fluids such as water droplets at the opening of the housing, thereby further preventing the fluids from entering the inside of the housing and avoiding undesirable contact failures.

[0057] In this disclosure, the term "apparatus" refers to an apparatus or device that includes at least a substrate having an electronic circuit, a housing for accommodating the substrate, and a connector including a terminal. Specifically, the term "apparatus" refers to an apparatus or device that includes the above-mentioned computer, etc.

[0058] The term "electronic circuit" generally refers to an electric circuit including semiconductor elements such as transistors, capacitors, etc. There are no particular limitations on such electronic circuits.

[0059] The present invention will be described below with reference to specific embodiments. Although the description will be made with reference to the drawings as necessary, the various elements and configurations in the drawings are merely shown as schematic and illustrative examples for the purpose of understanding the present invention, and the appearance and / or dimensional ratios may differ from the actual ones.

[0060] In each drawing, the shape of the connector is described based on an XYZ coordinate system in which the Z axis is a normal line in the Z1-Z2 direction of an XY plane parallel to the X axis in the X1-X2 direction shown in FIG. 1(C) and the Y axis in the Y1-Y2 direction perpendicular to the X axis. For convenience of explanation, the Z1 direction may be referred to as the upward direction, and the Z2 direction may be referred to as the downward direction.

[0061] [First embodiment] A connector according to a first embodiment of the present disclosure is a connector 10 including a terminal 3, as shown in, for example, FIGS. 1 and 2 , The terminal 3 has a first end (3a) for electrical connection to another terminal (not shown) and a second end (3b) for connection to a substrate; The connector 10 has a plurality of protrusions 2 that are provided so as to face an opening 31 of a housing 30 for accommodating a board 20 and be positioned inside the opening 31, A plurality of protrusions 2 each protrude outward from the surface of the connector body 1 and are arranged in a direction (for example, the Y-axis direction and / or the Z-axis direction in FIG. 1(C)) that crosses the terminals 3. The terminals 3 may be arranged, for example, in the X-axis direction shown in FIG. 1(C).

[0062] 1 and 2, a connector 10 according to a first embodiment of the present disclosure has a connector body 1 and a plurality of protrusions 2 protruding outward from a surface of the connector body 1. The connector body 1 has a terminal 3 disposed so as to penetrate a portion of the connector body 1. The terminal 3 has two ends (3a, 3b), the first end (3a) can be electrically connected to another terminal (not shown) and the second end (3b) can be electrically connected to the substrate 20 (see Figures 1(A) and 2(C)). The second end (3b) of the terminal 3 can be connected to an electronic circuit provided on the substrate 20 by soldering or the like in a conventional manner (see FIG. 12). The terminal 3 may be rod-shaped or plate-shaped. Considering the connection to the substrate 20 by soldering, the terminal 3 is preferably plate-shaped from the viewpoints of strength and the area of ​​connection by soldering. The substrate 20 may be parallel to the XY plane and coupled to the lower surface of the connector body 1 (see FIGS. 1(A) and 2(C)).

[0063] Here, Fig. 1(A) is a perspective view of the connector 10 as viewed from the side of the board 20. Fig. 1(B) is a perspective view of the connector 10 as viewed from the side where it connects to other terminals (not shown). Fig. 1(C) is a perspective view of the connector 10 together with the housing 30 as viewed from the side where it connects to other terminals (not shown) (however, the side of the housing 30 is omitted for ease of explanation).

[0064] The multiple protrusions 2 provided on the main body 1 of the connector 10 may be positioned inside or on the inner side of the opening 31 of the housing 30, with at least a portion of them facing the opening 31 of the housing 30 (see Figure 2(C)).

[0065] Here, FIG. 2(A) shows a partial cross section of the connector (showing a cross section along Z-Z' in FIG. 2(B)). FIG. 2(B) shows the connector seen from the side that connects to other terminals (not shown) together with the housing 30. FIG. 2(C) shows a cross section along X-X' of the connector in FIG. 2(B). FIG. 2(D) shows a cross section along Y-Y' of the connector in FIG. 2(B).

[0066] The relationship between multiple protrusions 2 provided on main body 1 of connector 10 and opening 31 of housing 30 is shown in Fig. 3. Note that Fig. 3, particularly Fig. 3(B), corresponds to a partial cross section viewed from above in Fig. 2(A).

[0067] Here, Fig. 3(A) shows a schematic diagram of an opening 31 provided in a housing 30. The opening 31 can receive at least some of the multiple protrusions 2 provided in the connector body 1. The opening 31 also has a space or opening provided for disposing and / or positioning the connector 10 (particularly the connector body 1) (see Fig. 2, particularly Fig. 2(B)).

[0068] The opening 31 has a plurality of recesses (areas surrounded by dotted lines) 32 having a shape that can correspond to the plurality of protrusions 2 provided on the connector body 1. In the illustrated embodiment, the plurality of protrusions 2 provided on the connector body 1 have a plate-like box shape as shown in Fig. 8(A), for example, and therefore the recesses 32 provided in the opening 31 of the housing 30 preferably have a complementary shape that can correspond to the shape of such protrusions 2. More specifically, the recesses 32 may have a box shape.

[0069] For example, as shown in FIG. 3(B), multiple convex portions 2 provided on connector body 1 can be wholly or partially accommodated within multiple concave portions 32 provided in opening 31 of housing 30 (see FIG. 1(C) and FIG. 2(A) and FIG. 2(B)).

[0070] The multiple protrusions 2 are preferably aligned in a straight line as shown by the dashed line in Fig. 3(B). By aligning the multiple protrusions 2 in a straight line, even if the connector is subjected to "shaking" or "vibration," the force received can be more uniformly distributed by contacting the opening 31 of the housing 30, particularly the wall of the recess 32, at a surface or point, preferably at a surface. As a result, the stress applied to the terminal 3 can be further reduced, and poor contact can be suppressed.

[0071] The multiple protrusions 2 can be arranged around the entire circumference of the connector body 1 (see FIG. 2(B)). When protrusions are arranged at the corners of the connector body 1, the protrusions may have an L-shape as shown in the figure. By having the protrusions have such an L-shape, even if the connector is tilted due to being "shaken" or "vibrated" as in the conventional case (see FIG. 13), the force received can be dispersed well at the corners.

[0072] It is preferable that the plurality of protrusions 2 are arranged at equal pitches. For example, as shown in Fig. 3(B), it is preferable that the pitches P1 and P2 between any two protrusions are the same. The pitch between any two convex portions is not particularly limited and can be determined arbitrarily.

[0073] When the protrusion 2 has a plate-like shape, for example, the longitudinal dimension L1 of the protrusion 2 shown in FIG. 8(A) is not particularly limited and can be determined arbitrarily. The dimension L2 of the protrusion 2 in the height direction (direction perpendicular to the longitudinal direction) is not particularly limited and can be determined arbitrarily. The dimension L3 of the protrusion 2 in the thickness direction is not particularly limited and can be determined arbitrarily.

[0074] The protrusion 2 preferably has a rectangular cross-sectional shape, for example, as shown in Fig. 3(B). As shown in the figure, the cross-sectional shape of the protrusion 2 is not limited to a quadrangle such as a rectangle, and may be a substantially rectangular shape such as a trapezoid, rhombus, or parallelogram (see Fig. 5(B)).

[0075] A space (S) may be formed by separation (or gap) between the recess 32 (preferably a wall portion) provided in the opening 31 of the housing 30 and the protrusion 2 provided in the connector body 1 (see Figures 3(A) and 3(B)).

[0076] The presence of the space (S) limits the movement of the protrusion 2 inside the recess 32, and when the connector is subjected to "shaking" or "vibration," the protrusion 2 moves in the horizontal direction (in other words, the Y-axis direction shown in FIG. 1(C)) and / or the vertical direction (in other words, the X-axis direction shown in FIG. 1(C)) and comes into contact with the wall surface of the recess 32, thereby dispersing the force received more uniformly. As a result, the stress applied to the terminal 3 can be further reduced, and poor contact can be further suppressed.

[0077] A space (S) may exist around each protrusion 2, and there is no particular limitation on the distance between the recess 32 and the protrusion 2. For example, the separation distances (or spacing distances) d1 to d6 in the horizontal direction (Y-axis direction) shown in Fig. 3(B) may be the same or different, and can be determined independently and arbitrarily. The separation distances (or gaps) d7 to d9 in the vertical direction (X-axis direction) may be the same or different, and can be determined independently and arbitrarily.

[0078] For example, as shown in FIG. 3(C), when the connector is subjected to "shaking" or "vibration" and the connector body is tilted obliquely as in the conventional case (see FIG. 13(B)), the wall surface of the recess 32 can restrict the movement of the protrusion 2 for each block, and the force received by the connector body can be transmitted to the wall surface of the recess 32 by contacting the protrusion 2 with the recess 32, preferably by contacting the surfaces of the protrusion 2 with the recess 32, and the received force can be dispersed further. As a result, the stress on the terminals provided in the connector body can be significantly reduced. This effect can be achieved not only when the force is received in the horizontal direction (Y-axis direction) but also when the force is received in the vertical direction (X-axis direction) and / or the up-down direction (Z-axis direction). In other words, the connector can achieve the same effect even when the force is received from any direction.

[0079] In order to enhance such an effect, for example, as shown in Fig. 4, a stopper 33 may be provided around the recess 32. The stopper 33 can exhibit the above-mentioned effect prominently in the vertical direction (X-axis direction). The stopper 33 may be formed integrally with the opening 31 or separately.

[0080] As a further improvement, for example, as shown in Figs. 5(A) and 5(B), the cross-sectional shapes of a recess 32' and a protrusion 2' that can be provided in an opening 31' may both be changed to a trapezoid.

[0081] By making the cross-sectional shapes of the recess 32' and the protrusion 2' trapezoidal, the force received can be dispersed more uniformly even when the connector body receives a force from the horizontal direction (Y-axis direction), the vertical direction (X-axis direction) and / or the up-down direction (Z-axis direction), or even when the connector body receives a force from an oblique direction (see FIG. 5(C)). In other words, the same effect can be achieved more remarkably even when the connector body receives a force from any direction.

[0082] For example, as shown in Fig. 5(B), the space (S) between the convex portion 2' and the concave portion 32' can be preferably formed by the convex portion 2' and the concave portion 32' having similar shapes. In other words, it is preferable that the surfaces constituting the convex portion 2' and the concave portion 32' are positioned approximately parallel to each other.

[0083] For example, the separation distance (or separation distance) d shown in FIG. 10 ~d 15 may be the same or different and can be determined independently and arbitrarily. For example, if the connector body is tilted as shown in Figure 5(C), the separation distance d 10 ~d 15 d 10 From d 15 It may be gradually increased over the 15 From d 10 (The distance d may be gradually decreased from d to d). If the connector body is tilted in the opposite direction to that shown in FIG. 5(C), 10 ~d 15 d 15 From d 10 It may be gradually increased over the 10 From d 15(It may be gradually decreased over time.) This allows for a significant reduction in stress even when tilted at a larger angle. The separation distance (or gap distance) d in the vertical direction (X-axis direction) shown in FIG. 5(B) 16 ~d 18 may be the same or different and can be determined independently and arbitrarily.

[0084] Here, the shape of the main surface of the protrusion is not limited to a quadrangle such as the rectangle shown in Fig. 6(A), and may be a substantially rectangular shape such as a trapezoid as shown in Fig. 6(B). By having such a shape, the contact area between the protrusion 2'' and the opening 31'' can be increased not only in the vertical and horizontal directions (X-axis direction and Y-axis direction) but also when the protrusion 2'' is tilted obliquely in the up-down direction (Z-axis direction), and the force received can be distributed more uniformly.

[0085] In this way, the connector according to the first embodiment of the present disclosure is provided with multiple protrusions, so that even if the connector body is subjected to an external force due to "jerking" or "vibration," the force is received by a surface or a point, preferably by a surface, and the force can be dispersed and released. In addition, the stress on the terminals provided on the connector body can be further reduced. As a result, the connection between the terminals and the board, more specifically the connection by solder, can be protected, and undesirable contact failures can be avoided.

[0086] [Second embodiment] The connector according to the second embodiment of the present disclosure is a connector including a terminal 3, The terminal 3 has a first end (3a) for electrical connection to another terminal (not shown) and a second end (3b) for connection to a substrate; The connector has a plurality of protrusions 2 provided so as to face an opening 31 of a housing 30 for accommodating a substrate 20 and to be positioned inside the opening 31; A plurality of protrusions 2 each protrude outward from the surface of the connector body 1 and are arranged in a direction crossing the terminals 3 (for example, in the Y-axis direction and / or the Z-axis direction), The opening 31 of the housing 30 has a plurality of recesses 32 for receiving the plurality of protrusions 2, A space (S1) that can be formed by separation (or separation) exists between the recess 32 provided in the opening 31 of the housing 30 and the protrusion 2 provided in the connector body 1, The space (S1) is a space provided for retaining a fluid.

[0087] The connector of the second embodiment is similar to the connector 10 of the first embodiment, but is characterized in that, as shown in the partial cross-sectional view of Figure 7(B), for example, a space (S1) formed by separation (or gap) between a recess 32 (see Figure 3(A)) provided in the opening 31 and a protrusion 2 provided in the connector body 1 is provided to retain fluids such as water droplets.

[0088] For example, as shown in the perspective view of FIG. 7(A), fluid such as water droplets may infiltrate along the direction of the arrow. However, in the connector of the second embodiment, the space (S1) that can be formed by the separation between the recess 32 (preferably a wall portion) provided in the opening 31 and the protrusion 2 provided in the connector body 1 allows the fluid to be retained in the space (S1). More specifically, the fluid can be retained in the space (S1) by capillary action and / or surface tension. As a result, the fluid can be prevented from infiltrating into the space (S2) that can be formed between the housing 30 and the connector body 1 at the front side. In the connector of the second embodiment, the presence of multiple such protrusions 2 dramatically improves the drip-proof effect.

[0089] The space (S1) is formed by making it larger than the conventional clearance between parts, and by increasing the volume of the space (S1), it is possible to retain a larger amount of fluid. Such an invention and effect would not be easily conceived of from a conventional invention that aims to reduce the clearance between parts. Furthermore, it would not be easily conceived of from an invention that is premised on the use of a sealing material, such as the invention described in Patent Document 1.

[0090] The distance (e.g., D2 and D4 shown in FIG. 7(B)) between the recess 32 (preferably a wall portion) provided in the opening 31 of the housing 30 and the protrusion 2 provided in the connector body 1 is preferably smaller than the distance (e.g., D5 shown in FIG. 7(B)) between the housing 30 and the connector body 1. By adjusting these distances, the fluid can be more easily and quickly retained in the space (S1) by capillary action and / or surface tension.

[0091] The ratio of the distance D2 or D4 to the distance D5 (the ratio of D2 / D5 or D4 / D5) may be less than 1, and can be determined arbitrarily.

[0092] The separation distances D2 and D4 may be the same or different. It is preferable that the distance D2 is smaller than the separation distance D4. This makes it possible to suppress the intrusion of fluids at a closer position. The distances D2 and D4 can be determined independently and arbitrarily.

[0093] The values ​​of the distance D2 and / or the distance D4 are d1 to d 18 The values ​​of d1 to d2 shown in FIG. 18 From the viewpoint of suppressing the intrusion of fluids at a closer position, the value of is preferably smaller than the distance D5.

[0094] The distance D5 is not particularly limited and can be determined arbitrarily.

[0095] In the opening 31 of the housing 30, the ratio of the separation distance D2 to the dimension D1 in the height direction (Z-axis direction) of the recess (the ratio D2 / D1) is not particularly limited and can be determined arbitrarily. In the opening 31 of the housing 30, the ratio of the separation distance D4 to the dimension D3 in the vertical direction (X-axis direction) of the recess (the ratio D4 / D3) is not particularly limited and can be determined arbitrarily.

[0096] In FIG. 7, the protrusion 2 is disposed inside the opening 31 , but the outer surface of the protrusion 2 may be flush with the outer surface of the opening 31 .

[0097] The protrusion 2 may have at least one selected from the group consisting of passages, grooves, holes, and pores for retaining fluids. Fluids such as water droplets can also be retained in such passages, grooves, holes, and pores.

[0098] For example, as shown in Fig. 8(B) and Fig. 9 and Fig. 10, some of the protrusions 2 may have passages 50. The passages 50 do not have to penetrate through the protrusions 2. In other words, the passages 50 may be grooves. The passage 50 may be formed in the lower part of the protrusion 2, more specifically, so that the passage 50 contacts the connector body 1. In the illustrated embodiment, the passage 50 is located in the center of the lower part of the protrusion 2, but the position of the passage 50 is not particularly limited.

[0099] The dimension L1 of the protrusion 2 in the longitudinal direction (for example, the Y-axis direction) relative to the dimension L of the passage 50 in the longitudinal direction (for example, the Y-axis direction) 50 Ratio (L 50 / L1) is not particularly limited and can be determined arbitrarily. L 50 can be determined arbitrarily without any particular limitation.

[0100] For example, as shown in FIG. 9, the distance D 50 is preferably smaller than the distance D5 between the housing 30 and the connector body 1, and is further preferably smaller than the separation distance D2 and / or D4 between the protrusion 2 and the recess 32.

[0101] Distance D to distance D5 50 Ratio of (D 50 / D5) is less than 1. 50 It is preferable that the ratio of / D5 is smaller.

[0102] D 50 The value of can be determined arbitrarily without any particular limitation.

[0103] FIG. 10 shows a connector according to a second embodiment of the present disclosure including a protrusion 2 having a passage 50. FIG. 10(A) shows a partial cross section of the connector (cross section taken along Z-Z' in FIG. 10(B)). FIG. 10(B) shows the connector together with the housing 30 viewed from the side that connects to other terminals (not shown). FIG. 10(C) shows a cross section taken along X-X' of the connector in FIG. 10(B). FIG. 10(D) shows a cross section taken along Y-Y' of the connector in FIG. 2(B).

[0104] The protrusion 2 may have a groove, a hole and / or a hole instead of or in addition to the passage 50. For example, a groove, a hole and / or a hole may be formed at the top of the protrusion 2. Note that such a passage, a groove, a hole and / or a hole may be formed in the protrusion of the first embodiment.

[0105] The connector of the present disclosure may be a waterproof connector or a non-waterproof connector. More specifically, a sealant may be disposed between the connector body 1 and the opening 31 and / or between the protrusion 2 and the opening 31 to enhance waterproof performance.
