Description

Connector and connector structure
Technical Field
The invention relates to a connector and a connector structure.
Background
There is a connector that is directly attached to a housing or the like of an apparatus by being inserted and fitted into a through hole provided in the housing or the like (for example, refer to patent document 1). The connector is mounted on a panel, and has a spring-like locking portion extending in an insertion direction of a through hole in a side surface thereof for locking with the through hole provided in the panel. When the connector is inserted into the through hole from a direction perpendicular to the panel, first, the locking portion elastically contracts to fit the opening of the through hole when passing through the through hole of the panel. When the connector is further inserted into the through hole, the locking portion returns to its original shape after passing through the through hole, and is locked with the panel at the opening end of the through hole on the back surface of the panel. Thereby, the connector is held on the panel.

Disclosure of Invention
In recent years, miniaturization of devices has been advanced, and a connector is required to be low in height. In the connector of patent document 1, the locking portion is elastically deformed when passing through the through hole, and then is locked to the panel by utilizing the difference in shape at the time of restoration. Therefore, if the holding force is to be increased, the length of the locking portion in the insertion direction needs to be increased to obtain a stroke for elastic deformation. However, if the length of the locking portion is increased, the locking portion protrudes greatly from the back surface of the panel when the connector is mounted on the panel. Therefore, in such a connector, it is difficult to achieve a low height while sufficiently obtaining a holding force with respect to the panel.
In view of the above, an object of the present invention is to provide a connector and a connector structure that can easily achieve a low height while sufficiently obtaining a holding force with respect to a base material such as a housing.
A connector according to an embodiment of the present invention is configured to be connected to a plate-like base material having a first surface and a second surface, and to be fitted to and removed from a counterpart connector in a first direction, the connector including a housing having: a main body disposed on the first surface side of the base material when the connector is connected to the base material, the main body having a fitting portion to be fitted with the counterpart connector; and an auxiliary portion that is inserted into a through hole formed in the base material when the connector is connected to the base material, wherein the auxiliary portion is disposed on the second surface side of the base material when the connector is connected to the base material, and wherein the housing is connected to the base material by sliding the housing relative to the base material in a second direction substantially parallel to the first surface, whereby at least a part of a peripheral edge portion of the through hole is sandwiched between the main body and the auxiliary portion in a third direction substantially perpendicular to the first surface.
Preferably, the first direction is a direction intersecting the second direction.
Preferably, the first direction intersects the second direction substantially perpendicularly.
Preferably, the first direction is a direction substantially parallel to the first surface of the substrate.
In addition, it is preferable that: the auxiliary portion has a biasing portion configured to be elastically deformable in the third direction and to press the second surface in the third direction.
In addition, it is preferable that: the force application part is configured as follows: the housing slides in the second direction, so that the urging portion contacts the second surface at least at a part of the peripheral edge portion of the through hole and presses the second surface.
In addition, it is preferable that: the urging portion is an arm-shaped leaf spring extending in the second direction and having an inclined portion inclined with respect to the second surface, and the opening edge of the through hole abuts the inclined portion and the urging portion elastically deforms in the third direction as the housing slides in the second direction.
In addition, it is preferable that: the housing further has: an engaging portion that engages with the base material in the second direction after the housing slides in a connection direction that is one direction of the second direction, and restricts movement of the housing in a separation direction that is a direction opposite to the connection direction; and an operation unit for releasing the engagement between the engagement unit and the base material.
The connector structure according to one embodiment of the present invention includes: the connector; a substrate coupled to the connector and having a first face and a second face; and a mating connector having a mating fitting portion to be fitted with the fitting portion of the connector.

Detailed Description
(first embodiment)
A connector and a connector structure according to a first embodiment of the present invention will be described below with reference to the drawings. The embodiments described below are merely examples, and the connector structure according to the present invention are not limited to the following embodiments. In the drawings, portions having the same function are denoted by the same reference numerals.
Fig. 1 to 3 show an example of the connector structure of the present embodiment. The connector structure ST of the present embodiment includes a connector 1, a substrate S to which the connector 1 is attached and connected, and a counterpart connector C1 electrically connected to the connector 1. As shown in fig. 2, the connector 1 is fitted to the mating connector C1 to be electrically connected to the mating connector C1. In the present embodiment, the mating connector C1 is preferably mounted on the mating substrate CS.
In the present specification, the direction in which the mating connector C1 is fitted to the connector 1 is referred to as a fitting direction D11, and the direction opposite to the fitting direction D11, i.e., the direction in which the mating connector C1 is pulled out of the connector 1 is referred to as a disconnection direction D12. The fitting direction D11 and the disengaging direction D12 are collectively referred to as a first direction D1. In the present embodiment, the first direction D1 is one of directions substantially parallel to the first surface Sa of the substrate S. In the present embodiment, one of the directions substantially parallel to the first surface Sa of the substrate S is set as the second direction D2. Specifically, the second direction D2 is a direction intersecting the first direction D1, and more preferably is a direction substantially perpendicular to the first direction D1. In the present embodiment, the second direction D2 is a direction in which the connector 1 slides, and in the second direction D2, as described later, a direction in which the housing 2 of the connector 1 engages with the substrate S is referred to as a connection direction D21, and a direction opposite to the connection direction D21, that is, a direction in which the housing 2 is disengaged from the substrate S is referred to as a separation direction D22. In the present embodiment, the third direction D3 is a direction substantially perpendicular to the first surface Sa of the substrate S. Specifically, the third direction D3 is a direction substantially perpendicular to both the first direction D1 and the second direction D2. In the present specification, a direction from the second surface Sb (see fig. 3) of the substrate S toward the first surface Sa along the third direction D3 is also referred to as "upper", and a direction from the first surface Sa toward the second surface Sb along the third direction D3 is also referred to as "lower". In addition, when the terms "upper surface", "lower surface", etc. are used, the side far from the first surface Sa of the substrate S in the third direction D3 is referred to as "upper", and the side near to the first surface Sa of the substrate S in the third direction D3 is referred to as "lower".
As shown in fig. 1, the connector 1 is a connector paired with the counterpart connector C1, and is fitted to or separated from the counterpart connector C1 in the first direction D1. In the present embodiment, the connector 1 is a male connector, and the counterpart connector C1 is a female connector, but the types of the connector 1 and the counterpart connector C1 are not particularly limited, and the connector 1 may be a female connector, and the counterpart connector C1 may be a male connector. In the example of fig. 1, the connector 1 and the counterpart connector C1 are connectors for board-to-board connection, but may be connectors for board-to-board connection. The connector 1 includes a fitting portion 31, and the fitting portion 31 is fitted to a mating fitting portion C31 of the mating connector C1. The connector structure ST of the present embodiment has a horizontal fitting structure in which the counterpart connector C1 is fitted to the connector 1 in a direction (first direction D1) parallel to the first surface Sa of the substrate S. However, the connector structure ST is not particularly limited, and may have other fitting structures such as a vertical fitting structure in which the counterpart connector C1 is fitted to the connector 1 in a direction perpendicular to the first surface Sa of the substrate S. The connector 1 is preferably used for a display device such as a liquid crystal display or an organic EL display, or an electronic device such as a mobile phone or a tablet terminal, which is particularly required to be miniaturized, but the use of the connector 1 is not particularly limited.
The substrate S is a member on which the connector 1 is mounted. The substrate S is not particularly limited, and is, for example, a case of an electronic device, a circuit board, a metal plate, or the like. In the present embodiment, the substrate S is a backlight chassis of a display device such as a liquid crystal display device. As shown in fig. 3, the substrate S includes a first surface Sa, a second surface Sb that is an opposite surface thereof, and a through hole Sh having a predetermined shape that penetrates between the first surface Sa and the second surface Sb. The shape of the through hole Sh is not particularly limited, and in the present embodiment, the through hole Sh is configured to be capable of inserting an auxiliary portion 4 described later to the second surface Sb side of the base material S. In the present embodiment, the peripheral edge portion Sp of the through hole Sh has a biasing portion contact portion Sp1, and after the connector 1 is slid in the second direction D2 (the connecting direction D21), a biasing portion 41 (see fig. 4A to 6B, etc.) described later is brought into contact with the biasing portion contact portion Sp1 on the second surface Sb. In the present embodiment, the biasing portion contact portion Sp1 is formed of a protruding portion that extends from the opening edge Sp of the through hole Sh extending in the second direction D2 toward the center of the through hole Sh in the first direction D1. More specifically, as shown in fig. 3, the peripheral edge portion Sp of the through hole Sh has a pair of biasing portion contact portions Sp1, and the pair of biasing portion contact portions Sp1 protrude from the central portions of the parallel two sides Sh1, sh2 extending along the second direction D2 of the substantially rectangular opening so as to approach each other in the first direction D1. Thus, the through hole Sh has a wide portion Sha having a width in the first direction D1 and a narrow portion Shb having a width in the first direction D1.
Substrate materialThe material of S is not particularly limited as long as it has various characteristics that enable the connector 1 to be mounted. The substrate S may be made of, for example, a metal material such as Al (aluminum) or stainless steel, an organic material such as ABS (acrylonitrile-butadiene-styrene copolymer resin), or Al 2 O 3 Inorganic materials such as (alumina) and fiber reinforced plastics such as glass epoxy. As will be described later, the substrate S preferably has an engaged portion S1 on the first surface Sa side, and the engaged portion S1 is preferably engaged with the connector 1 when the connector 1 is mounted on the substrate S by sliding in the second direction D2 (the connecting direction D21). In the example of fig. 3, the engaged portion S1 is a convex portion protruding from the first surface Sa. The engaged portion S1 will be described in detail later.
Returning to fig. 1, the mating substrate CS is a circuit board on which the mating connector C1 is mounted. In the present embodiment, as described later, the counterpart substrate CS is a plate-like substrate elongated in the first direction D1 and accommodated in the substrate accommodation portion 312 of the connector 1, and one end thereof is mounted with the counterpart connector C1. Although the type of the counter substrate CS is not particularly limited, in the present embodiment, the counter substrate CS is an LED substrate mounted on the base material S as a backlight chassis. The material of the counter substrate CS is not particularly limited as long as it has many characteristics that the counter connector C1 can be mounted, but is, for example, a metal material such as Al or stainless steel, an organic material such as ABS, al 2 O 3 Inorganic materials such as the above, fiber reinforced plastics such as glass epoxy, and the like. For example, the counter substrate CS has a contact pad (not shown) on the surface. The mating connector C1 is electrically connected and fixed to the mating substrate CS by soldering or the like at the position of the contact pad.
The mating connector C1 is fitted to the connector 1. The mating connector C1 has a mating fitting portion C31 to be fitted with the fitting portion of the connector 1. The counterpart connector C1 moves in the first direction D1 (fitting direction D11) with respect to the counterpart substrate CS together with the counterpart substrate CS, so that the counterpart connector C1 is connected to the connector 1 as shown in fig. 2.
In the present embodiment, as shown in fig. 1, the width of the mating connector C1 is narrower than the width of the mating substrate CS (the length in the second direction D2), but the mating connector C1 may have the same width as the mating substrate CS. In the present embodiment, the mating connector C1 is mounted on the mating substrate CS such that the end portion on the mating direction D11 side of the mating connector C1 is on the disengaging direction D12 side with respect to the end portion of the mating substrate CS. However, it may be: the mating connector C1 may be mounted on the mating substrate CS so that the end of the mating connector C1 on the mating direction D11 side coincides with the end of the mating substrate CS, and may be: the mating connector C1 is mounted on the mating substrate CS such that an end portion on the mating direction D11 side of the mating connector C1 protrudes from an end portion of the mating substrate CS.
Fig. 4A and fig. 5A to 6B show an example of the connector 1 according to the present embodiment. The connector 1 of the present embodiment includes a housing 2 mounted on a substrate S (see fig. 1) and a connection terminal 6 electrically connected to a counterpart connection terminal (not shown) of a counterpart connector C1 (see fig. 1). The connector 1 is configured to connect the counterpart board CS to the electric wires 7 (see fig. 1).
The case 2 includes a main body 3, and when the case 2 is attached to and connected to the substrate S (see fig. 3), the main body 3 is disposed on the first surface Sa (see fig. 3) side of the substrate S. In the present embodiment, the housing 2 further includes: an auxiliary portion 4 disposed on the second surface Sb (see fig. 3) side of the base material S; and a through-hole 5 disposed in the through-hole Sh (see fig. 3) of the base material S. The auxiliary portion 4 and the insertion portion 5 are provided in a state where the case 2 is connected to the substrate S by sandwiching. The case 2 is preferably attached to the substrate S so as to be movable within a predetermined range along at least one of the first direction D1, the second direction D2, and the third direction D3. The specific structure will be described later.
The material of the housing 2 is not particularly limited as long as it has insulation properties and strength to be able to connect with the base material S (see fig. 3) and to fit with the counterpart connector C1 (see fig. 1), but is preferably formed of a resin such as engineering plastic such as PBT (polybutylene terephthalate).
As shown in fig. 7A and 7B, when the case 2 is connected to the substrate S, the auxiliary portion 4 is inserted into the through hole Sh of the substrate S. Then, as shown in fig. 7B and 7C, the housing 2 is slid in the connecting direction D21. Thereby, as shown in fig. 7C, the substrate S is sandwiched between the main body 3 and the auxiliary portion 4. Therefore, the auxiliary portion 4 is accommodated in the through hole Sh at a position before sliding (see fig. 9A) of the housing 2, and overlaps the peripheral edge portion Sp of the through hole Sh at a position after sliding (see fig. 9B) when viewed from the third direction D3. In the example of fig. 7A to 7C, as shown in fig. 6A and 6B, the auxiliary portion 4 has a substantially H-shape protruding in two directions in the first direction D1 from both end portions in the second direction D2 when viewed from below. The auxiliary portion 4 has an auxiliary portion side wide portion 4a having a width in the first direction D1 and an auxiliary portion side narrow portion 4b having a width in the first direction D1. As shown in fig. 9A, the auxiliary portion side wide portion 4a of the auxiliary portion 4 is configured to be larger than the width of the narrow portion Shb of the through hole Sh in the first direction D1, and when the case 2 is slid in the connecting direction D21, the auxiliary portion side wide portion 4a of the auxiliary portion 4 engages with the peripheral edge portion Sp of the through hole Sh as shown in fig. 9B, thereby restricting the case 2 from falling off from the base material S in the third direction D3. The width of the through-hole 5 in the first direction D1 is smaller than the width of the narrow portion Shb of the through-hole Sh, and the through-hole 5 is slidable in the second direction D2 within the through-hole Sh. The method of connecting the housing 2 to the substrate S will be described later.
In the present embodiment, as shown in fig. 4A, 6A, and 6B, the auxiliary portion 4 has a biasing portion 41 configured to be elastically deformable in the third direction D3. As shown in fig. 7C, the urging portion 41 is configured to: the urging portion 41 is provided on a side facing the second surface Sb of the base material S, and presses the second surface Sb of the base material S in the third direction D3. In the case where the auxiliary portion 4 has the elastically deformable urging portion 41, as shown in fig. 11A, even if the thickness of the base material S to be connected is changed, the auxiliary portion 4 is deformed according to the thickness of the base material S. Therefore, the substrate S having various thicknesses can be sandwiched between the main body 3 and the auxiliary portion 4, and the connector 1 can cope with various substrates S having different thicknesses. In addition, even in a state where the housing 2 is connected to the substrate S by being sandwiched, the auxiliary portion 4 is deformed in accordance with the force applied in the third direction D3, and therefore the housing 2 can move in the third direction D3. Therefore, when the connector 1 is fitted with the counterpart connector C1, the impact at the time of fitting is weakened by moving the housing 2 in the third direction D3, so that the connector 1 is not easily damaged.
The urging portion 41 is preferably made of an elastic member from the viewpoint of durability, and the urging portion 41 is more preferably made of a leaf spring from the viewpoint of simplicity of construction. In the present embodiment, as shown in fig. 4A and 4B, the urging portion 41 is constituted by an arm-shaped leaf spring extending in the second direction D2, which has an inclined portion 411 inclined with respect to the second surface Sb of the base material S. In this way, in addition to the above-described effects, the urging portion 41 can be easily manufactured. As shown in fig. 8B, when the housing 2 slides, the inclined portion 411 is elastically deformed by abutting against the opening edge Se of the biasing portion contact portion Sp1, contacts the second surface Sb of the biasing portion contact portion Sp1, and presses the second surface Sb.
In the present embodiment, the inclined portion 411 extends in the separation direction D22 as shown in fig. 4A, but may extend in the connection direction D21 as in the modification shown in fig. 4B. The biasing portion 41 is not limited to a leaf spring, and may be formed of, for example, a coil spring or rubber capable of pressing the second surface Sb (see fig. 7C, etc.) of the base material S in the third direction D3.
In the present embodiment, as shown in fig. 6A and 6B, the urging portion 41 is provided in the auxiliary portion-side wide portion 4a, and as shown in fig. 9A and 9B, the urging portion 41 protrudes in two directions (in the present embodiment, the first direction D1) perpendicular to the second direction D2, which is the direction in which the housing 2 slides. However, the biasing portion 41 may not be provided in the auxiliary portion side wide portion 4a. For example, as in the modification shown in fig. 10A and 10B, the auxiliary portion 4 may be formed in a substantially rectangular shape, and the biasing portion 41 may be provided so as to protrude in the connecting direction D21. The entire auxiliary portion 4 may be made of rubber, or an elastic member such as a leaf spring, so that the entire auxiliary portion 4 functions as the biasing portion 41.
As shown in fig. 4A, 6A, and 6B, the auxiliary portion 4 may further include a restricting portion 42, and the restricting portion 42 may be configured to restrict the interval between the main body 3 and the auxiliary portion 4 in the third direction D3. The interval between the main body 3 and the auxiliary portion 4 in the third direction D3 defines the maximum thickness of the substrate S (see fig. 7C) sandwiched by the main body 3 and the auxiliary portion 4. In the case where the auxiliary portion 4 includes the urging portion 41, as shown in the example of fig. 4A, the restriction portion 42 is preferably configured such that the interval G42 between the main body 3 and the restriction portion 42 in the third direction D3 is larger than the interval G41 between the main body 3 and the urging portion 41. In this case, when the case 2 is connected to the base material S, the urging portion 41 is elastically deformed within the range of the gap G42 between the main body 3 and the restriction portion 42.
As shown in fig. 6A and 6B, the restricting portion 42 is provided as the auxiliary portion side wide portion 4a. In the example of fig. 6A and 6B, the restricting portion 42 protrudes in two directions (in the present embodiment, the first direction D1) perpendicular to the second direction D2, which is the direction in which the housing 2 slides (see also fig. 9A and 9B). However, the restricting portion 42 may protrude in any one of the directions (the fitting direction D11 or the disengaging direction D12 in the present embodiment) perpendicular to the second direction D2, or may protrude in the second direction D2.
As shown in fig. 4A, 6A, and 6B, the insertion portion 5 is configured to connect the auxiliary portion 4 to the main body 3 in the third direction D3. In the present embodiment, as shown in fig. 9B, the through-hole 5 is preferably configured to: when the housing 2 is mounted on the substrate S, a gap G1 is provided between the through-hole 5 and the opening edge Se in at least one of the first direction D1 and the second direction D2 of the through-hole Sh of the substrate S. Through the gap G1, the case 2 is connected to the substrate S in a state of being movable in at least one of the first direction D1 and the second direction D2. In addition, when the gap G1 exists in both the first direction D1 and the second direction D2, the case 2 can be connected to the base material S in such a state: can move in both the first direction D1 and the second direction D2, and can rotate about an axis extending in the third direction D3.
In the present embodiment, as shown in fig. 7C, the case 2 includes a first engaging portion 321 that engages with the substrate S and an operating portion 322 that releases the engagement of the first engaging portion 321 with the substrate S. The first engaging portion 321 and the operating portion 322 are not particularly limited, but are preferably provided on the main body 3 having the fitting portion 31.
In the present embodiment, the operation unit 322 moves the housing 2 in the separation direction D22 while pulling up the operation unit 322 upward, thereby releasing the engagement between the first engagement portion 321 and the substrate S. In the present embodiment, the first engaging portion 321 and the operating portion 322 are integrally provided. In the example of fig. 7C, the first engaging portion 321 and the operation portion 322 are provided on the arm portion 32 extending in an arm shape in a predetermined direction from the housing 2. In this way, the first engaging portion 321 and the operating portion 322 can be formed with a simple structure. In the example of fig. 7C, the arm 32 is formed on the lower surface 3b side of the body 3 facing the first surface Sa of the substrate S so as to extend in the separation direction D22, and the first engaging portion 321 and the operation portion 322 are integrally provided at the end on the separation direction D22 side. However, the first engaging portion 321 and the operating portion 322 may be provided on at least one of the main body 3 and the auxiliary portion 4.
The first engaging portion 321 is configured to: for example, after the housing 2 slides in the connection direction D21, the housing 2 is engaged with the engaged portion S1 of the base material S in the second direction D2, and movement of the housing 2 in the separation direction D22 is restricted. In the present embodiment, as shown in fig. 4A, 6A, and 6B, the first engagement portion 321 is a wall portion provided at an end portion of the arm portion 32 in the separation direction D22, and is configured to: in the second direction D2, the engaging portions are engaged with the wall portions provided on the convex engaged portions S1 of the base material S so as to face each other. The first engaging portion 321 and the engaged portion S1 are not particularly limited as long as the movement of the housing 2 in the separation direction D22 can be restricted. For example, as in the modification shown in fig. 11B, the engaged portion S1 may be a concave portion formed in the base material S, and the first engaging portion 321 may be a convex portion that is fitted in the engaged portion S1 formed as a concave portion. In the present embodiment, it is preferable that when the housing 2 is connected to the substrate S, the housing 2 has a gap G2 between the first engaging portion 321 and the engaged portion S1 in at least one of the first direction D1 and the second direction D2, as shown in fig. 7C, in correspondence with the direction of the gap G1 (see fig. 9B) between the through-hole 5 and the opening edge Se of the through-hole Sh. Thus, the movement of the housing 2 is not hindered.
The operation portion 322 is not particularly limited, but in the present embodiment, as shown in fig. 7C, the operation portion 322 is provided integrally with the first engaging portion 321 at an end portion of the arm portion 32 extending in the separation direction D22 on the separation direction D22 side on the lower surface (the facing surface facing the first surface Sa of the base material S) 3b of the main body 3. When the engaged portion S1 has a convex shape, it is preferable that: the arm portion 32 has a recess 323 for accommodating the engaged portion S1 on the lower surface 3B, and the recess 322 is formed in a shape corresponding to the engaged portion S1 of the base material S at a position after the auxiliary portion 4 is inserted into the through hole Sh and before the housing 2 slides in the connecting direction D21 (see also fig. 6A and 6B).
In the present embodiment, the connector 1 is connected to the substrate S by sandwiching the substrate S between the main body 3 and the auxiliary portion 4. An example of this method is described below with reference to fig. 7A to 7C. The present invention is not limited by the following description.
First, as shown in fig. 7A, the auxiliary portion 4 of the case 2 is inserted into the through hole Sh of the base material S from above the base material S (see also fig. 8A). CL in the drawing is a reference line indicating the position of the housing 2, and in fig. 7A to 7C, is the center line of the fitting portion 31. Here, as shown in fig. 9A, at the position before sliding of the housing 2, the external shape of the auxiliary portion 4 other than the end portion on the sliding direction, i.e., the connecting direction D21 side, is a shape along the shape of the through hole Sh when viewed from the third direction D3. In the present embodiment, as shown in fig. 7B, the engaged portion S1 of the base material S is accommodated in the recess 323 of the arm 32. In this way, when the auxiliary portion 4 is inserted into the through hole Sh, the housing 2 is aligned with respect to the base material S, and thus the housing 2 is easily slid.
Next, as shown in fig. 7B and 7C, the housing 2 is slid in the second direction (connection direction D21). In the present embodiment, as shown in fig. 8A and 8B, the inclined portion 411 of the arm-shaped leaf spring of the urging portion 41 abuts against the opening edge Se of the through hole Sh on the second surface Sb side of the base material S as the housing 2 slides. When the housing 2 is slid further, the inclined portion 411 is brought into contact with the second surface Sb of the base material S in at least a part of the peripheral edge portion Sp (urging portion contact portion Sp 1) of the through hole Sh of the base material S, and elastically deforms in the third direction D3, thereby pressing the second surface Sb. In the present embodiment, since the inclined portion 411 is formed in the shape of an arm extending in the separation direction D22 as shown in fig. 4A, the inclined portion 411 can be reasonably deformed when the inclined portion 411 abuts against the opening edge Se. When the body 3 has the arm 32 and the recess 323 is provided in the arm 32, the recess 323 reaches the engaged portion S1 of the base material S by elastically deforming the arm 32 in the third direction D3 on the first surface Sa side of the base material S.
When the housing 2 is slid further, the first engaging portion 321 of the arm portion 32 can engage with the engaged portion S1. At least a part of the peripheral edge portion Sp (the biasing portion contact portion Sp 1) of the through hole Sh is sandwiched between the main body 3 and the auxiliary portion 4 in the third direction D3 substantially perpendicular to the first surface Sa of the substrate S. As a result, as shown in fig. 7C, the case 2 is connected to the substrate S, and movement of the case 2 in the separation direction D22 is restricted. In order to release the connection between the housing 2 and the substrate S, the housing 2 may be moved in the separation direction D22 while the operation portion 322 is pulled up in fig. 7C. In the present embodiment, after the case 2 is connected to the base material S, as shown in fig. 9B, the urging portion 41 (the auxiliary portion-side wide portion 4 a) of the auxiliary portion 4 overlaps at least a portion of the peripheral edge portion Sp (the narrow portion Shb) of the through hole Sh in the first direction D1, as viewed from the third direction D3. However, as in the modification shown in fig. 10A and 10B, the urging portion 41 of the auxiliary portion 4 may overlap at least a part of the peripheral edge portion Sp of the through hole Sh in the connection direction D21, as viewed from the third direction D3.
In the present embodiment, the holding force of the connector 1 on the substrate S can be sufficiently obtained by sandwiching the substrate S between the main body 3 and the auxiliary portion 4. In the present embodiment, it is not necessary to lengthen the length of the locking portion in the insertion direction (third direction D3) in which the connector 1 is inserted into the substrate S as in the conventional art described above, and the substrate S is held between the main body 3 and the auxiliary portion 4 by sliding the housing 2 in the second direction (connection direction D21) parallel to the first surface Sa of the substrate S. Therefore, if the auxiliary portion 4 having the minimum thickness required for the sandwiching is provided, the amount by which the connector 1 protrudes from the second surface Sb of the base material S can be reduced after the connector 1 is connected to the base material S. Thereby, the connector 1 is easily reduced in height.
In the case where the auxiliary portion 4 includes the elastically deformable biasing portion 41, the auxiliary portion 4 deforms in the third direction D3 according to the thickness of the base material S, for example, when the thickness deviation of the base material S is large, or when different base materials S having different thicknesses are used. Therefore, the same case 2 can be used to sandwich substrates S of various thicknesses between the main body 3 and the auxiliary portion 4.
The structure is preferably as follows: as shown in fig. 7C, when the case 2 is connected to the substrate S, the urging portion 41 presses the peripheral edge portion Sp (urging portion contact portion Sp 1) of the through hole Sh at the central region of the through hole Sh in the second direction D2. In this way, the main body 3 and the auxiliary portion 4 hold the substrate S more stably.
In the present embodiment, the first direction D1 (the fitting direction D11 and the separating direction D12) and the second direction D2 (the connecting direction D21 and the separating direction D22) intersect substantially perpendicularly. In this way, when the housing 2 is connected to the base material S, the housing 2 is not easily moved in the second direction D2 due to the force applied in the fitting direction D11 or the disengaging direction D12 when the connector 1 is fitted to or removed from the counterpart connector C1. Accordingly, the force applied during fitting or removal is not likely to escape in a direction other than the fitting direction D11 or the removal direction D12, and fitting or removal between the connector 1 and the counterpart connector C1 is facilitated. However, the first direction D1 is not particularly limited, and may be the same as the second direction D2 or the third direction D3, or may be a direction other than the second direction D2 and the third direction D3. The above-described effect can be achieved if the first direction D1 is a direction intersecting the second direction D2. For example, the angle between the fitting direction D11 and the separation direction D22 may be 60 to 120 degrees, preferably 70 to 110 degrees, and more preferably 80 to 100 degrees. In the present embodiment, the first direction D1 is a direction substantially parallel to the first surface Sa of the substrate S. In this way, by inserting the counterpart connector C1 along the first surface Sa of the substrate S, the counterpart connector C1 is easily fitted with the connector 1.
As shown in fig. 1, the main body 3 of the connector 1 includes a fitting portion 31, and the fitting portion 31 is fitted to a mating fitting portion C31 of the mating connector C1, and is configured to: so that the counterpart connector C1 can be fitted and removed in the first direction D1. As described above, the first direction D1 is not particularly limited, but in the present embodiment, the first direction D1 is a direction intersecting substantially perpendicularly with the second direction D2 and substantially parallel to the first surface Sa of the substrate S. The fitting portion 31 includes a connector housing portion 311 that houses the mating fitting portion C31 of the mating connector C1. In the present embodiment, the fitting portion 31 includes a substrate accommodating portion 312 for accommodating the opposite substrate CS. In the present embodiment, the fitting portion 31 includes a connector guide portion 313 for guiding the mating fitting portion C31 to the connector housing portion 311, and a board guide portion 314 for guiding the mating board CS to the board housing portion 312.
Fig. 4A, 5A to 6B, and 7C show the fitting portion 31 of the main body 3 of the present embodiment. As shown in fig. 5A and 5B, the connector housing portion 311 is a recess having an internal space 311s, and the internal space 311s is sized to accommodate a mating fitting portion C31 of the mating connector C1 (see fig. 1). The connector housing 311 is formed to open in the disengaging direction D12 of the main body 3 and extend in the first direction D1. The internal space 311s of the connector housing portion 311 is formed in a shape corresponding to the mating fitting portion C31 (see fig. 1), and is provided continuously in the third direction D3 with the internal space 312s of the board housing portion 312 (see fig. 5B) (see also fig. 4A). The connector housing portion 311 is provided with the connection terminal 6 (see fig. 5B). When the connection terminal 6 (see fig. 5B) is fitted to the mating connector C1 (see fig. 1), it contacts a mating connection terminal (not shown) of the mating connector C1. Thereby, the connector 1 is electrically connected to the counterpart connector C1 (see fig. 1).
In the present embodiment, as shown in fig. 1, the main body 3 of the connector 1 includes the second engagement portion 33 engaged with the engaged portion C11 of the counterpart connector C1, and the disconnection of the counterpart connector C1 from the connector 1 is suppressed. When the mating connector C1 is disengaged from the connector 1, the second engagement portion 33 may be operated to release the engagement between the second engagement portion 33 and the engaged portion C11.
As shown in fig. 5A and 5B, the connector guide portion 313 is provided on the disengagement direction D12 side with respect to the connector housing portion 311. When the mating connector C1 (see fig. 1) is oriented in the fitting direction D11, the connector guide portion 313 guides the mating fitting portion C31 (see fig. 1) to the connector housing portion 311. The shape and structure of the connector guide portion 313 are not particularly limited as long as the mating connector C1 (see fig. 1) can be guided to the connector housing portion 311 when the mating connector C31 (see fig. 1) is oriented in the mating direction D11. In the example of fig. 5A and 5B, in order to guide the mating fitting portion C31 (refer to fig. 1) in the second direction D2, the internal space 313s of the connector guide portion 313 is narrowed toward the fitting direction D11 in the second direction D2. Specifically, the connector guide portion 313 includes a pair of guide surfaces 313p inclined so that the interval in the second direction D2 becomes shorter as it approaches the fitting direction D11. The internal space 313s of the connector guide 313 may be narrowed in the third direction D3 toward the fitting direction D11 so as to guide the mating fitting portion C31 in the third direction D3 (see fig. 1). The internal space 313s of the connector guide 313 may be narrowed in the fitting direction D11 in both the second direction D2 and the third direction D3 so as to guide the mating fitting portion C31 in both the second direction D2 and the third direction D3 (see fig. 1). The internal space 313s may be narrowed by providing the guide surface 313p of the connector guide portion 313 in a planar shape, or may be narrowed by providing the guide surface 313p in a curved shape. In the case where the guide surface 313p is curved, if the curved surface is convex toward the fitting direction D11 (see the broken line portion in fig. 5A), the mating fitting portion C31 can be smoothly guided.
In the example of fig. 5A and 5B, the connector guide portion 313 is connected to the connector housing portion 311, and the internal space 313s of the connector guide portion 313 and the internal space 311s of the connector housing portion 311 are continuous in the first direction D1.
As shown in fig. 6A and 6B, the substrate housing portion 312 is formed as a recess opening in the detachment direction D12 of the main body 3, and the recess has an inner space 312s having a size capable of housing one end portion of the opposite substrate CS (see fig. 1). Like the connector housing portion 311, the substrate housing portion 312 extends along the first direction D1. In the example of fig. 6A and 6B, the internal space 312s of the board housing portion 312 is formed in a shape corresponding to one end portion of the counterpart board CS (see fig. 1), and is provided continuously in the third direction D3 with the internal space 311s of the connector housing portion 311 as described above (see also fig. 4A).
As shown in fig. 6A and 6B, the substrate guide 314 is provided on the detachment direction D12 side with respect to the substrate housing 312. When the mating connector C1 (see fig. 1) is brought close to the fitting direction D11, the board guide 314 guides the mating board CS to the board housing 312. The shape and structure of the board guide 314 are not particularly limited as long as the mating board CS can be guided to the board storage 312 when the mating connector C1 (see fig. 1) is brought close to the fitting direction D11. In the example of fig. 6A and 6B, the internal space 314s of the substrate guide 314 is narrowed toward the fitting direction D11 in the second direction D2 and the third direction D3 so as to guide one end portion of the opposite substrate CS in the second direction D2 and the third direction D3 (see also fig. 4B). Specifically, the substrate guide 314 includes a pair of guide surfaces 314p inclined so that the interval in the second direction D2 becomes shorter as it approaches the fitting direction D11. The internal space 314s of the substrate guide 314 may be narrowed in any one of the second direction D2 and the third direction D3 toward the fitting direction D11 so as to guide one end portion of the opposite substrate CS in any one of the second direction D2 and the third direction D3. The internal space 314s may be narrowed by providing the guide surface 314p of the substrate guide 314 in a planar shape, or may be narrowed by providing the guide surface 314p in a curved shape. In the case where the guide surface 314p is curved, if the curved surface is convex toward the fitting direction D11 (see the broken line portion in fig. 6A), the one end portion of the counter substrate CS can be smoothly guided.
In the example of fig. 6A and 6B, the substrate guide portion 314 is connected to the substrate housing portion 312, and the internal space 314s of the substrate guide portion 314 and the internal space 312s of the substrate housing portion 312 are continuous in the first direction D1.
In the present embodiment, as shown in fig. 7C, the substrate housing portion 312 is formed as a recess having an internal space 312S of a size capable of housing the opposite substrate CS on the lower surface 3b of the main body 3 facing the first surface Sa (see fig. 1) of the base material S. The substrate guide 314 is formed as a recess in a lower surface 3b of the main body 3 facing the first surface Sa (see fig. 1) of the substrate S. More specifically, the substrate housing portion 312 and the substrate guide portion 314 are opened toward the first surface Sa of the base material S at the lower surface 3b of the main body 3. In this case, as shown in fig. 2, when the connector 1 is fitted to the counterpart connector C1, the counterpart substrate CS contacts the first surface Sa of the base material S, and therefore, the warpage of the counterpart substrate CS in the third direction D3 is corrected. However, as shown in fig. 4C, the substrate housing portion 312 and the substrate guide portion 314 may be closed by the main body 3 below the lower surface 3b of the main body 3 without opening to the first surface Sa of the base material S.
In the present embodiment, as described above, the connector 1 includes the board housing portion 312 and the connector housing portion 311, and the connector guide portion 313 is provided on the detachment direction D12 side with respect to the connector housing portion 311, and the board guide portion 314 is provided on the detachment direction D12 side with respect to the board housing portion 312. Accordingly, by accommodating the counterpart substrate CS in the connector 1 while being guided by the substrate guide portion 314 and accommodating the counterpart connector C1 in the connector 1 while being guided by the connector guide portion 313, the offset of the counterpart connector C1 in the insertion direction is corrected. In this way, the counterpart connector C1 is positioned by the guide of the two guide portions 313, 314 to correct the offset in the insertion direction, and therefore the counterpart fitting portion C31 of the counterpart connector C1 is not easily forcibly inserted into the fitting portion 31 of the connector 1. This can prevent the connector 1 from being damaged due to the offset of the mating connector C1 in the insertion direction. At the same time, damage to the counterpart connector C1 is also prevented.
An example of a fitting method of the connector 1 of the present embodiment and the counterpart connector C1 will be described below with reference to fig. 1, 2, and 12A to 15B. The present invention is not limited to the following description.
When mating connector C1 is mated with connector 1 of the present embodiment, first, mating connector C1 and mating substrate CS are inserted into connector guide 313 and substrate guide 314, respectively, and guided in mating direction D11, as shown in fig. 12A. Here, in general, the connector is more likely to be damaged by a force applied forcibly than a component such as a circuit board. Therefore, the counter substrate CS is preferably guided by the substrate guide 314 before the connector guide 313 guides the counter connector C1. As described above, the mating substrate CS is guided by abutting against the substrate guide 314, and the mating connector C1 mounted on the mating substrate CS is positioned in the second direction D2 and/or the third direction D3. Thereafter, when the counterpart connector C1 is guided by the connector guide portion 313, the counterpart connector C1 does not come into contact with the connector guide portion 313, or even if it comes into contact with the connector guide portion 313, the impact at the time of contact with the connector guide portion 313 is reduced. Accordingly, the connector 1 can be fitted to the counterpart connector C1 without forcibly applying a force to the connector 1, and therefore, damage to the connector 1 is further prevented. At the same time, damage to the counterpart connector C1 is further prevented.
The structure for guiding the opposite substrate CS to the substrate guiding portion 314 at the beginning is not particularly limited. As shown in fig. 12A, the mating connector C1 may be mounted on the mating substrate CS such that an end portion on the mating direction D11 side of the mating connector C1 is spaced apart from an end portion on the mating direction D11 side of the mating substrate CS in the disengaging direction D12 side. As shown in fig. 12B and 12C, the mating connector C1 may be mounted on the mating substrate CS so that the position of the end portion of the mating connector C1 on the mating direction D11 side in the first direction D1 coincides with the end portion of the mating substrate CS on the mating direction D11 side. In this case, in order to obtain the above-described effect, as shown in the example of fig. 12B and 12C, the connector guide portion 313 may be provided to extend in the fitting direction D11 more than the board guide portion 314. The mating connector C1 may be mounted on the mating substrate CS so that the end of the mating connector C1 on the mating direction D11 side protrudes from the end of the mating substrate CS. In this case, in order to obtain the above-described effect, the connector guide portion 313 may be provided to extend in the fitting direction D11 more than the board guide portion 314 in accordance with the amount of protrusion of the mating connector C1 from the mating board CS.
The internal space 313s of the connector guide portion 313 and the internal space 314s of the board guide portion 314 may be narrowed to the same extent (e.g., angle) as each other in the fitting direction D11 as shown in fig. 12B, or may be narrowed to different extents as shown in fig. 12C. From the viewpoint of reducing the impact when the counterpart connector C1 is in contact with the housing 2, as shown in fig. 12C, the degree of narrowing of the inner space 313s of the connector guide 313 is preferably smaller than the degree of narrowing of the inner space 314s of the substrate guide 314.
As described above, in the present embodiment, the auxiliary portion 4 preferably includes the biasing portion 41 elastically deformable in the third direction D3 (see fig. 7C, etc.), and the through-hole portion 5 preferably includes the gap G1 (see fig. 9B, etc.) between the opening edge Se of the through-hole Sh of the substrate S in at least one of the first direction D1 and the second direction D2. In this case, the housing 2 has a gap G2 between the first engaging portion 321 and the engaged portion S1 corresponding to the gap G1 (see fig. 7C, etc.). Accordingly, as shown in fig. 14A to 15B, the case 2 is preferably connected to the substrate S so as to be movable in at least one of the first direction D1, the second direction D2, and the third direction D3 within a predetermined range corresponding to the gap G1 or the gap G2.
For example, in the case where the housing 2 is movable in the first direction D1, as shown in fig. 14A, when the counterpart connector C1 is inserted into the connector 1, the housing 2 is moved in the first direction D1 by a force applied in the fitting direction D11. Accordingly, when the mating connector C1 is brought into contact with the housing 2, the force applied in the fitting direction D11 becomes weak, and therefore damage to the connector 1 is further prevented. At the same time, damage to the counterpart connector C1 and the counterpart substrate CS is also prevented.
In addition, when the housing 2 is movable in the second direction D2, as shown in fig. 14B, the housing 2 moves in the second direction D2 in response to the offset of the opposite substrate CS in the insertion direction with respect to the fitting direction D11 when the opposite substrate CS is in contact with the substrate guide 314. In addition, when the housing 2 is movable in the third direction D3, as shown in fig. 15A, the housing 2 is moved in the third direction D3 in response to the offset M of the opposite substrate CS in the insertion direction with respect to the fitting direction D11 when the opposite substrate CS is in contact with the substrate guide 314. By such movement of the housing 2, the force applied in the fitting direction D11 becomes weak when the counterpart substrate CS is in contact with the housing 2, and therefore damage to the connector 1 is further prevented. At the same time, damage to the counterpart connector C1 and the counterpart substrate CS is further prevented.
In addition, when the housing 2 is movable in both the first direction D1 and the second direction D2, as shown in fig. 14C, the housing 2 is not only movable in parallel in the first direction D1 and the second direction D2, but also rotatable about an axis R3 extending in the third direction D3. In the case of being movable in both the second direction D2 and the third direction D3, as shown in fig. 15B, the housing 2 is not only movable in parallel in the second direction D2 and the third direction D3, but also rotatable about the axis R1 extending in the first direction D1. In the case of being movable in both the third direction D3 and the first direction D1, although not particularly shown, the housing 2 is not only movable in parallel in the third direction D3 and the first direction D1, but also rotatable about an axis extending in the second direction D2. When the movement is possible in any of the first direction D1, the second direction D2, and the third direction D3, the movement can be performed not only in parallel in the first direction D1, the second direction D2, and the third direction D3, but also around any axis. Thereby, the housing 2 moves more flexibly in response to the offset of the counterpart substrate CS forming an angle with respect to the fitting direction D11 in the insertion direction, and therefore, damage of the connector 1 and damage of the counterpart connector C1 and the counterpart substrate CS are further prevented.
In fig. 14A to 14C, the case where the mating substrate CS is first brought into contact with the housing 2 (the substrate guide 314) to move the housing 2 is described. Therefore, illustrations of the connector housing portion 311 and the connector guide portion 313 are omitted. However, the housing 2 may be moved by bringing the mating connector C1 into contact with the housing 2 (the connector guide 313) first with respect to the mating substrate CS. However, as described above, from the viewpoint of the ease of damage of the connector 1, it is preferable that the housing 2 moves when the counterpart substrate CS is in contact with the housing 2 (the substrate guide 314).
In the case where the board guide 314 is initially configured to guide the mating board CS, as shown in fig. 13, the gap Gc between the mating connector C1 and the connector housing portion 311 is preferably smaller than the gap Gs between the mating board CS and the board housing portion 312. Thus, after roughly positioning by the contact between the mating substrate CS and the substrate guide 314, finely positioning is performed by the contact between the mating connector C1 and the connector guide 313. This can further reduce the impact when the mating connector C1 abuts against the connector guide portion 313, and can more accurately position the mating connector C1.
After the positioning in the above manner, as shown in fig. 1 and 2, when the counterpart connector C1 is further moved in the fitting direction D11, the second engaging portion 33 engages with the engaged portion C11 of the counterpart connector C1, and the connector 1 is fitted with the counterpart connector C1 (see also fig. 13). In the example of fig. 1 and 2, in order to release the fitting of the connector 1 to the counterpart connector C1, the housing 2 may be moved in the disengaging direction D12, which is the direction opposite to the fitting direction D11, while pressing the second engaging portion 33 downward.
(other embodiments)
In the above embodiment, the substrate housing portion 312 is provided in the case 2, but the substrate housing portion 312 may not be provided. That is, the housing 2 may not be fitted to the mating substrate CS, and the fitting portion 31 may be fitted to the mating connector C1. The connector guide 313 and the board guide 314 may not be provided in the housing 2. That is, the mating connector C1 may be directly accommodated in the board accommodating portion 312 without being guided by the connector guide portion 313, or the mating substrate CS may be directly accommodated in the board accommodating portion 312 without being guided by the substrate guide portion 314. The case 2 may be fixed to the substrate S without being removably connected to the substrate S. That is, the through-hole 5 may have no gap G1 between the through-hole Sh and the opening edge Se of the through-hole Sh of the base material S, and the housing 2 may have no gap G2 between the first engaging portion 321 and the engaged portion S1. The auxiliary portion 4 may not have the biasing portion 41. That is, the form of the auxiliary portion 4 is not limited as long as it sandwiches the substrate S with the main body 3. The housing 2 and the base material S may not have the first engaging portion 321 and the engaging portion S1, respectively. That is, the case 2 may not engage with the substrate S, and may hold the substrate S. The connector 1 and the counterpart connector C1 may not have the second engagement portion 33 and the engaged portion C11, respectively. That is, the connector 1 may not engage with the counterpart connector C1, and may be electrically connected to the counterpart connector C1.
