Description

[0001] This application is a divisional application of an application with a filing date of April 23, 2020, application number 2020103256335, and invention name “Connector”. Technical Field

[0002] The present disclosure relates to connectors. Background Art

[0003] Conventionally, connectors such as substrate-to-substrate connectors have been used to electrically connect a pair of parallel circuit substrates. Such connectors are mounted on the corresponding surfaces of a pair of circuit substrates facing each other, and are engaged and connected to each other (see, for example, Patent Document 1).

[0004] Fig.11 is a perspective view showing a conventional connector.

[0005] In the figure, 811 is a connector base mounted on a circuit substrate (not shown), and the connector base has a pair of elongated protrusions 812 extending in the length direction. A plurality of terminals 861 are mounted on the protrusions 812 side by side along the length direction of the connector.

[0006] In addition, when the connector is mated with a docking connector (not shown), the protrusions 812 are respectively inserted into a pair of grooves formed on the docking base of the docking connector. Thus, the plurality of terminals 861 are respectively in contact with and connected to docking terminals (not shown) installed side by side in the grooves.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2001-126789

[0008] However, in conventional connectors, since the terminals 861 are integrally formed with the base 811, the intervals between the protrusions 812 become narrower in the case of miniaturization, and the spacing between the terminals 861 decreases, making manufacturing difficult. Generally, since the terminals 861 are integrated with a pair of protrusions 812 of the base 811 by a molding method called overmolding or insert molding, if the intervals between the protrusions 812 become narrower and the spacing between the terminals 861 decreases, it is difficult to accurately set the terminals 861 at positions corresponding to the pair of protrusions 812 in the molding die of the base 811. Summary of the invention

[0009] Here, an object is to solve the problems of the conventional connector to enable narrowing of the intervals between the protrusions for mounting a plurality of terminals, and thereby provide a connector that is easy to manufacture, capable of miniaturization, and has high reliability.

[0010] Therefore, the connector includes: half-body parts, each half-body part includes a connector body and a plurality of terminals mounted on the connector body; a body end part, which makes the connector bodies of each half-body part butt against each other and is formed at both ends of the connector body; and a reinforcing fitting mounted on the body end part. Each of the connector bodies is a component integrated with the terminals by the first insert molding, and includes: a convex part extending in the length direction of the connector body and holding the terminals; and an embedded part connected to both ends of the length direction of the convex part. The body end part includes a covering part, which covers the embedded part of each connector body, and the covering part is a component integrated with the embedded part and the reinforcing fitting by the second insert molding.

[0011] In another connector, further, extended end portions are connected to both ends of the protrusion in the length direction, and the embedded portion extends from the extended end portions.

[0012] In another connector, further, the reinforcing fitting includes: an upper plate extending in the width direction of the connector body; a pair of left and right legs connected to the left and right side edges of the upper plate and extending downward; and an end wall outer covering portion and an end wall inner covering portion connected to the front and rear side edges of the upper plate and extending downward. The embedded portion is arranged so that at least a portion overlaps with the upper plate, the legs, the end wall outer covering portion and the end wall inner covering portion when viewed from the top and bottom, front and back, and left and right directions.

[0013] In another connector, further, the embedded portion of each connector body includes: parallel inner side surfaces extending in the length direction of the connector body and facing the embedded portion of the other connector body, and the distance L2 between the parallel inner side surfaces facing each other is smaller than the width L1 of the inner surface covering portion of the end wall of the reinforcing accessory which is configured to face the gap between the parallel inner side surfaces facing each other.

[0014] In another connector, further, the end wall inner surface covering portion faces the inclined inner side surface of the embedded portion and has a gap between the inclined inner side surface, and the inclined inner side surface is connected to each of the mutually facing parallel inner side surfaces and is inclined relative to the length direction of the connector body.

[0015] In another connector, further, the embedded portion of each connector body includes: an outer side surface extending in the length direction of the connector body and facing the foot of the reinforcing accessory, and the length L4 of the outer side surface is smaller than the length L3 of the foot.

[0016] In another connector, further, the extended end portion of each connector body is inclined inward in the width direction of the connector and extends from both ends of the protrusion in the length direction, and the width of the body end portion is smaller than the width of the connector.

[0017] The connector pair includes the connector described in the present disclosure and a mating connector mated with the connector.

[0018] The connector according to the present disclosure can narrow the intervals between the protrusions on which the plurality of terminals are mounted, is easy to manufacture, can be miniaturized, and has improved reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0088] The embodiments will be described in detail below with reference to the accompanying drawings.

[0089] Figure 1 is a perspective view showing a first connector according to the present embodiment, Figure 2 is an exploded view showing the first connector according to the present embodiment, and Figure 3 is a perspective view showing the left half of the first connector according to the present embodiment.

[0090] In the figure, reference numeral 1 is a first connector as one of a pair of substrate-to-substrate connectors of the connector of the present embodiment. The first connector 1 is a surface-mounted connector mounted on the surface of a first substrate (not shown) as a mounting component, and is mated with a second connector 101 as a mating connector described later. In addition, the second connector 101 is the other of a pair of substrate-to-substrate connectors, and is a surface-mounted connector mounted on the surface of a second substrate (not shown) as a mounting component.

[0091] Note that, although the first connector 1 and the second connector 101 of the present embodiment are ideally used to electrically connect the first substrate and the second substrate as substrates, they can also be used to electrically connect other components. Examples of the first substrate and the second substrate include printed circuit substrates, flexible flat cables (FFCs), flexible printed circuit substrates (FPCs) used in electronic devices, etc., and can also be any type of substrate.

[0092] In addition, the expressions indicating directions such as up, down, left, right, front and rear used to illustrate the actions and structures of the various parts of the first connector 1 and the second connector 101 in this embodiment are not absolute but relative directions, and although these expressions are suitable when the various parts of the first connector 1 and the second connector 101 are in the postures shown in the figures, when these postures change, these directions should be interpreted differently corresponding to the changes.

[0093] Furthermore, the first connector 1 is configured as follows: a pair of left and right half-body parts (i.e., a left half-body part 10A and a right half-body part 10B) are connected to each other using a first reinforcing fitting 51 as a reinforcing fitting and a cover part 16 integrally formed by a molding method called overmolding, outsert molding, or even insert molding (hereinafter referred to as "insert molding"). Note that the left half-body part 10A and the right half-body part 10B are identical components arranged to face each other left and right, and therefore, in the case of a unified description, the half-body part 10 is described. The shapes of the left half-body part 10A and the right half-body part 10B in a plan view (shape projected onto an XY plane) are respectively approximately gate-shaped, and the space between the joined left half-body part 10A and the right half-body part 10B is an elongated groove part 13 extending in the longitudinal direction (X-axis direction) of the first connector 1. The groove part 13 is a through hole opened on the upper surface and the lower surface of the first connector 1.

[0094] Note that in this embodiment, for ease of explanation, in the first connector 1, a pair of half-body parts 10 (i.e., two half-body parts 10) are arranged in parallel, however, three or more half-body parts 10 may be arranged in parallel. The half-body parts 10 do not necessarily have a substantially door-shaped shape, but may have any shape as long as both ends in the length direction can be joined by the first reinforcing fitting 51 and the covering part 16.

[0095] The half body 10 is integrally formed of an insulating material such as synthetic resin, and has a first base 11 as a connector body that is substantially gate-shaped in plan view. Each first base 11 includes a slender strip-shaped bottom plate 17 that extends in the longitudinal direction (X-axis direction) of the first base 11, and a first convex portion 12 that is integrally formed on the upper surface of the bottom plate 17 as a slender convex portion and extends in the longitudinal direction of the first base 11. The first convex portion 12 is a member having an inverted U-shaped cross section, and has a curved mating surface 12a located on the upper side (Z-axis positive direction side) and an outer side surface 12b and an inner side surface 12c connected to the left and right sides of the mating surface 12a. The outer side surface 12b and the inner side surface 12c are a pair of mutually parallel and facing planes, and extend in the longitudinal direction of the first base 11. Note that the dimension of the first protrusion 12 in the width direction (Y-axis direction) is smaller than the dimension of the bottom plate 17 in the width direction, and therefore, the bottom plate 17 protrudes outward in the width direction from the outer side surface 12b and the inner side surface 12c at the lower end (Z-axis negative direction side end) of the first protrusion 12. In addition, the lower surface of the bottom plate 17 is the mounting surface 17a of the first base 11 facing the surface of the first substrate.

[0096] Moreover, a first terminal 61 as a terminal is provided at each first protrusion 12. A plurality of (32 in the example shown in the figure) first terminals 61 are arranged at a predetermined pitch. The above-mentioned first terminal 61 is a component integrally formed by subjecting a conductive metal plate to processing such as stamping and bending, and includes: a main body portion 63 extending in the width direction of the first protrusion 12; a tail portion 62 connected to one end of the main body portion 63; a contact portion 65 bent at about 90 degrees, connected to the other end of the above-mentioned main body portion 63 and extending in the up-down direction; and an upper end portion 64 bent at about 90 degrees and connected to the upper end of the contact portion 65.

[0097] The body portion 63 is a portion embedded and held in the bottom plate portion 17. In addition, the tail portion 62 extends outward in the width direction from the bottom plate portion 17 and is connected to a connection pad (the connection pad is connected to a conductive trace on the first substrate) by welding or the like. Note that the conductive trace is usually a signal line. Moreover, the contact portion 65 is a portion that comes into contact with a second terminal 161 of the second connector 101 described later when the first connector 1 is mated with the second connector 101, and preferably includes a contact recess 65a recessed from the surface.

[0098] The first terminal 61 is formed integrally with the first base 11 by insert molding. That is, the first base 11 is formed by filling the cavity of the mold in which the first terminal 61 is preliminarily provided. Thus, the first terminal 61 is integrally mounted on the first base 11 in a state where the lower surfaces of the body portion 63 and the tail portion 62 are exposed to the mounting surface 17a of the bottom plate portion 17, and the surfaces of the contact portion 65 and the upper end portion 64 are exposed to the outer side surface 12b or the inner side surface 12c of the first protrusion 12 and the fitting surface 12a.

[0099] In addition, the plurality of first terminals 61 mounted on each first protrusion 12 are oriented so that the postures of the adjacent first terminals 61 are opposite to each other in the width direction of the first protrusion 12. In the example shown in the figure, among the first terminals 61 mounted on the first protrusion 12 of the left half body 10A, the first terminal 61 located at the front end (X-axis positive direction end) is oriented so that the tail 62 protrudes outward (Y-axis positive direction side), and the first terminal 61 located at the second position from the front end is oriented so that the tail 62 protrudes inward (Y-axis negative direction side). In this way, since the plurality of first terminals 61 are mounted on the first protrusion 12 in a manner alternately oriented in opposite directions, the spacing of the tails 62 protruding from both sides of the first protrusion 12 is twice the spacing of the first terminals 61. Therefore, the connection operation for the connection pad of the first substrate by welding or the like can be easily performed. Furthermore, the pitch of the contact portions 65 exposed on the outer side surface 12 b of the first protrusion 12 and the pitch of the contact portions 65 exposed on the inner side surface 12 c are also twice the pitch of the first terminals 61 .

[0100] In addition, since the first terminal 61 is a component integrated with the first base 11 by insert molding, it will not be separated from the first base 11. However, it is noted that for the sake of convenience in explanation, Figure 2 In the figure, the first terminal 61 is shown separately from the first base 11.

[0101] The first protruding end portions 18 of the main body end portions as the mating guide portions are respectively provided at both ends in the length direction of the first convex portion 12. The first protruding end portions 18 are members connected to both ends in the length direction of each first convex portion 12, and are formed to connect the left half body portion 10A and the right half body portion 10B. When the first connector 1 and the second connector 101 are mated, the first protruding end portions 18 function as insertion protrusions that are inserted into the mating recesses 122 of the second protruding end portions 121 of the second connector 101 described later.

[0102] The first protruding end portion 18 is constituted by the extended end portions 14 and the embedded portion 15 of the left and right half body portions 10 , the covering portion 16 , and the first reinforcing fitting 51 .

[0103] The extended end portions 14 extending in the length direction are integrally connected to both ends in the length direction of the first convex portion 12 of each half body 10, and the embedded portion 15 further extending in the length direction of the first convex portion 12 is integrally connected to each extended end portion 14. Note that the extended end portion 14 extends obliquely inwardly, and the embedded portion 15 extends in the length direction from a position eccentric inwardly at the end of the extended end portion 14, and is located at a position inside the outer side surface 12b of the first convex portion 12. That is, the extended end portion 14 of the left half body 10A extends obliquely in the right direction (negative direction of the Y axis), and the embedded portion 15 extends in the length direction from a position eccentric in the right direction at the end of the extended end portion 14. In addition, the extended end portion 14 of the right half body 10B extends obliquely in the left direction (positive direction of the Y axis), and the embedded portion 15 extends in the length direction from a position eccentric in the left direction at the end of the extended end portion 14.

[0104] Moreover, at least a portion of the extended end portions 14 of the left and right half-body portions 10 and the entire embedded portion 15 are covered by a covering portion 16 formed of an insulating material such as a synthetic resin. Specifically, the covering portion 16 is formed by insert molding the embedded portions 15 of the left and right half-body portions 10 close to each other and in a state where they are covered by the first reinforcing fitting 51. Thus, the extended end portions 14 and the embedded portion 15 of the left and right half-body portions 10, as well as the covering portion 16 and the first reinforcing fitting 51 are integrated to form the first protruding end portion 18, thereby combining the left and right half-body portions 10 with each other. However, the above-mentioned covering portion 16 does not necessarily have to cover the entire embedded portion 15, as long as the embedded portion 15 can be covered to a degree sufficient to combine the left and right half-body portions 10 with each other, but in order to make the bonding force the strongest, it is preferred to cover the entire embedded portion 15. Note that the covering portion 16 is a component formed integrally with other components by insert molding, and does not exist separately from other components, but for ease of explanation, Figure 2 Depicted as existing alone.

[0105] like Figure 3 As shown, the extended end portion 14 has an upper surface 14a located on the upper side, an outer side surface 14b and an inner side surface 14c connected to the left and right sides of the upper surface 14a, and a lower surface 14d located on the lower side. The lower surface 14d is located above the mounting surface 17a, and at least a portion of the lower surface 14d is covered by the covering portion 16. The upper surface 14a is substantially flush with the fitting surface 12a of the first protrusion 12. In addition, the inner side surface 14c is a surface that is inclined obliquely inward relative to the inner side surface 12c of the first protrusion 12. The outer side surface 14b includes: an inclined outer side surface 14b1 that is inclined obliquely inward relative to the outer side surface 12b of the first protrusion 12; and a parallel outer side surface 14b2 that is substantially parallel to the outer side surface 12b of the first protrusion 12. The parallel outer side surface 14b2 is substantially flush with the outer side surface of the covering portion 16 and forms a part of the outer side surface of the first protruding end portion 18.

[0106] In addition, the embedded portion 15 is a component of a substantially rectangular parallelepiped shape, and has an upper surface 15a located on the upper side, an outer side surface 15b and an inner side surface 15c located on the left and right sides, a lower surface 15d located on the lower side, and end surfaces 15e at both ends in the length direction of the first connector 1. The upper surface 15a and the lower surface 15d are planes parallel to each other, and the distance between the upper surface 15a and the lower surface 15d (i.e., the thickness of the embedded portion 15) is smaller than the thickness of the extended end portion 14 and the first protrusion 12. It is noted that the upper surface 15a is located below the fitting surface 12a, and the lower surface 15d is located above the mounting surface 17a. In addition, the outer side surface 15b is a plane substantially parallel to the outer side surface 12b of the first protrusion 12, but is located on the inner side of the outer side surface 12b, that is, close to the center in the width direction of the first base 11. Furthermore, the inner side surface 15c includes: a parallel inner side surface 15c1, which is substantially parallel to the inner side surface 12c of the first protrusion 12; and an inclined inner side surface 15c2, which is substantially parallel to the inner side surface 14c of the extended end portion 14. Furthermore, the end surface 15e is a plane orthogonal to the longitudinal direction of the first connector 1. Furthermore, the embedded portion 15 is entirely covered by the covering portion 16, that is, embedded in the covering portion 16.

[0107] In this way, since the extended end portion 14 extends obliquely inwardly and the embedded portion 15 is located at an inner position relative to the outer side surface 12b of the first protrusion 12, the width of the first protruding end portion 18 (the dimension in the Y-axis direction) can be smaller than the width of the first connector 1 (the distance between the outer side surfaces 12b of the left and right first protrusions 12). It is noted that when it is not necessary to make the width of the first protruding end portion 18 smaller than the width of the first connector 1, the extended end portion 14 does not have to be inclined inwardly, but can be extended straight. In addition, by directly extending the embedded portion 15 from both ends in the length direction of the first protrusion 12, the extended end portion 14 can be omitted. In this case, the size of the first connector 1 in the length direction can be reduced. In addition, when more than three half-body portions 10 are arranged in parallel, the extended end portion 14 can extend from both ends in the length direction of the first protrusion 12 to form a Y shape.

[0108] The first reinforcing fitting 51 is a member integrally formed by applying processing such as stamping and bending to a metal plate, and includes: a substantially rectangular upper plate 54 extending in the width direction of the first base 11; a substantially rectangular foot portion 55 connected to the left and right side edges of the upper plate 54 and extending downward; and an end wall outer surface covering portion 52 and an end wall inner surface covering portion 53 connected to the front and rear side edges of the upper plate 54 and extending downward. The tail portion 52a is connected to the lower end of the end wall outer surface covering portion 52. In addition, the width of the end wall outer surface covering portion 52 is greater than the width of the end wall inner surface covering portion 53.

[0109] As described above, the first reinforcing fitting 51 is integrated with the cover 16 to form the first protruding end 18. The upper plate 54 is embedded in the upper surface of the first protruding end 18, and the upper surface of the upper plate 54 is flush with the upper surface of the cover 16 to form most of the upper surface of the first protruding end 18. In addition, the left and right leg portions 55 are embedded in the left and right outer side surfaces of the first protruding end 18, and the outer side surfaces of the leg portions 55 are flush with the outer side surface of the cover 16 to form most of the outer side surface of the first protruding end 18. In addition, the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 are embedded in the end wall outer surface and the end wall inner surface of the first protruding end 18, and the outer surfaces of the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53 are flush with the end wall outer surface and the end wall inner surface of the cover 16 to form most of the end wall outer surface and the end wall inner surface of the first protruding end 18.

[0110] The tail portion 52a is bent about 90 degrees and connected to the lower end of the end wall outer cover portion 52, and extends outward in the length direction of the first base 11 and is connected to the connection pad (the connection pad is connected to the conductive trace on the first substrate) by welding or the like. The conductive trace is usually a power line. It is noted that if necessary, the lower end of the foot portion 55 can be close to or in contact with the surface of the first substrate. In this case, the lower end of the foot portion 55 is connected to the connection pad on the first substrate by welding or the like, thereby improving the connection strength of connecting the first reinforcing accessory 51 to the first substrate.

[0111] Next, a method of manufacturing the first connector 1 having the above-described configuration will be described.

[0113] The first terminal 61 is a member formed by bending a metal plate in the plate thickness direction and is manufactured by subjecting the metal plate to processing such as stamping and bending. Figure 4 As shown in FIG. 1 , a plurality of first terminals 61 are provided in a state of being connected to a flat terminal strip 68 as a strip material. Note that each first terminal 61 is formed by connecting the end of a tail portion 62 to the terminal strip 68 via an elongated connecting arm 68a, and the tail portion 62 is cut off from the connecting arm 68a at a cutting portion 68b, thereby forming a terminal strip 68. Figure 2 Parts shown.

[0114] Then, in the step of integrating with the first base 11 by insert molding, as shown in FIG. Figure 4 As shown, a plurality of first terminals 61 are provided in a state of being connected to a material strip 68 . Figure 4 An example of manufacturing the left half body 10A is shown, in which case a plurality of first terminals 61 oriented so that the tails 62 protrude outward (toward the positive direction of the Y axis) are connected to Figure 4 The terminal strip 68 on the right side of the middle portion is oriented so that the tail portion 62 protrudes inward (the negative direction of the Y axis) and is connected to the plurality of first terminals 61. Figure 4 The terminal strip 68 on the left side of the mold is placed in the first forming mold (not shown) in this state. By holding and operating the terminal strip 68 connected with the plurality of first terminals 61, the plurality of first terminals 61 are simultaneously positioned and placed in the forming mold.

[0115] Subsequently, the cavity of the molding die is filled with molten insulating material such as synthetic resin. In other words, the first insert molding is performed. Note that the insulating material may be any kind of material, but LCP (liquid crystal polymer) is used here. In the first insert molding, it is preferable to select the above material with attention paid to fluidity. Then, when the filled insulating material is cooled and solidified to form the first base 11, the molding die is opened and the first base 11 is taken out. Figure 4 The left half body 10A is shown with the terminal strip 68 connected to the first terminal 61. Similarly, the right half body 10B with the terminal strip 68 connected to the first terminal 61 is also manufactured.

[0116] Then, if Figure 4As shown, only the terminal strip 68 ( Figure 4 The terminal strip 68 on the left side of the first terminal 61 is cut off from the left half of the body 10A with the terminal strip 68 connected to the first terminal 61, and the terminal strip 68 ( Figure 4 Similarly, only the terminal strip 68 connected to the tail 62 protruding inwardly is cut off from the right half body 10B with the terminal strip 68 connected to the first terminal 61, while the terminal strip 68 connected to the tail 62 protruding outwardly is kept as it is.

[0117] Subsequently, as shown in FIG. 5 , the left half body 10A and the right half body 10B having the terminal strip 68 connected only to the tail portion 62 protruding outward are arranged in a second molding die (not shown) in a state facing each other. Specifically, the inner sides of the left and right half bodies 10 face each other, and the first bases 11 of the left and right half bodies 10 are parallel to each other, the mounting surfaces 17a of the first bases 11 of the left and right half bodies 10 are flush with each other, and the end surfaces 15e at both ends in the length direction are flush with each other, and the embedded portions 15 of the left and right half bodies 10 are close to each other but not in contact. Note that, as Fig. 7A As shown, the left and right half-body parts 10 facing each other are positioned so that the interval between the parallel inner side surfaces 15c1 of the facing embedded parts 15 is a predetermined distance L2, and are set in the secondary molding die.

[0118] Furthermore, the first reinforcing fitting 51 is set in the secondary molding die so as to cover at least a portion of the extended end portions 14 of the left and right half-body portions 10 and the entire embedded portion 15. In this case, the first reinforcing fitting 51 is set in a state where the end of its tail portion 52a is connected to the accessory tape 58 as a tape. Note that the tail portion 52a is cut off from the accessory tape 58 at the cutting portion 58b, so that the first reinforcing fitting 51 becomes as shown in FIG. Figure 2 Specifically, Fig. 7A , Fig. 8A and Figure 8B As shown, the first reinforcing accessory 51 is configured as follows: there is a gap between the upper plate 54 and the upper surface 15a of the embedded portion 15, there is a gap between the foot 55 and the outer side surface 15b of the embedded portion 15, there is a gap between the end wall outer covering portion 52 and the end surface 15e of the embedded portion 15, there is a gap between the end wall inner surface covering portion 53 and the inclined inner side surface 15c2 of the embedded portion 15, and the lower end of the foot 55 is located below the lower surface 15d of the embedded portion 15 and the height is approximately the same as the mounting surface 17a.

[0119] Subsequently, a molten insulating material such as a synthetic resin is filled in the molding die. That is, the second insert molding is performed. Note that the insulating material may be any kind of material, but here, the material is LCP selected by emphasizing fluidity as in the first insert molding. In the second insert molding, the insulating material can be selected by emphasizing strength and melt bonding with the insulating material of the first insert molding. Then, when the filled insulating material cools and solidifies to form the covering portion 16, the molding die is opened and the covering portion 16 is taken out. Fig. 6A , 6B The left and right half body parts 10 are shown with both ends in the longitudinal direction connected to each other by the first protruding end part 18 .

[0120] In this case, the left and right half parts 10 are integrated with the covering part 16 in a state where at least a part of the extended end part 14 and the entire embedded part 15 are covered by the covering part 16, and the first reinforcing fitting 51 is integrated with the covering part 16 in a manner covering at least a part of the outer side surface of the covering part 16. Specifically, Figure 7B , Figure 8C and Fig.8D As shown, the gaps between the upper plate 54, the leg portion 55, the end wall outer covering portion 52 and the end wall inner covering portion 53 of the first reinforcing fitting 51 and the upper surface 15a, the outer side surface 15b, the end surface 15e and the inclined inner side surface 15c2 of the embedded portion 15 are filled with the insulating material of the covering portion 16. In addition, the gaps between the mutually opposing parallel inner side surfaces 15c1 of the embedded portion 15 are also filled with the insulating material of the covering portion 16. In addition, the lower surface 15d of the embedded portion 15 is also filled with the insulating material of the covering portion 16, and the lower surface of the covering portion 16 is substantially flush with the mounting surface 17a. In addition, the parallel outer side surface 14b2 of the extended end portion 14 is substantially flush with the outer side surface of the covering portion 16 and forms a part of the outer side surface of the first protruding end portion 18.

[0121] like Fig. 7A As shown, since there is a gap between the end wall inner surface covering portion 53 of the first reinforcing fitting 51 and the inclined inner side surface 15c2 of the embedded portion 15 and the inclined inner side surface 15c2 is inclined, the molten insulating material filled into the cavity of the mold smoothly flows between the end wall inner surface covering portion 53 and the left and right inclined inner side surfaces 15c2 and between the parallel inner side surfaces 15c1 of the embedded portion 15 facing each other in the second insert molding, and fills the cavity without leaving any gap. In addition, the space between the end wall inner surface covering portion 53 and the left and right inclined inner side surfaces 15c2 increases, thereby increasing the filling amount of the insulating material.

[0122] In addition, if Fig. 7AAs shown, it is preferred that the dimension in the width direction at the end wall inner surface covering portion 53 of the first reinforcing fitting 51 of the first connector 1, which faces the gap between the parallel inner side surfaces 15c1 of the embedded portion 15, that is, the width L1, is set to be larger than the distance L2 which is the interval between the parallel inner side surfaces 15c1. In other words, it is preferably set to L1>L2. Note that the width of the end wall outer surface covering portion 52 is larger than the width of the end wall inner surface covering portion 53. Therefore, when viewed from the front-to-back direction (X-axis direction), the boundary between the parallel inner side surfaces 15c1 of the embedded portion 15 formed by the first insert molding and the covering portion 16 formed by the second insert molding is covered by the end wall outer surface covering portion 52 and the end wall inner surface covering portion 53, and is therefore difficult to separate, thereby increasing the strength of the first protruding end portion 18.

[0123] In addition, if Fig. 7A As shown, preferably, the dimension of the first connector 1 in the length direction at the foot 55 of the first reinforcing accessory 51, that is, the length L3, is set to be greater than the length L4 of the outer side surface 15b of the embedded portion 15. In other words, it is preferably set to L3>L4. And, the end of the outer side surface 15b close to the center in the length direction of the first connector 1 is preferably closer to the two ends in the length direction of the first connector 1 than the end of the foot 55 close to the center in the length direction of the first connector 1. Therefore, when viewed from the width direction (Y-axis direction), the boundary between the outer side surface 15b of the embedded portion 15 formed by the first insert molding and the covering portion 16 formed by the second insert molding is covered by the foot 55, and the strength of the first protruding end 18 is thereby improved.

[0124] Furthermore, the embedded portion 15 is provided so that at least a portion overlaps (i.e., is superimposed on) any one of the upper plate 54, the end wall outer surface covering portion 52, the end wall inner surface covering portion 53, and the leg portion 55 of the first reinforcing member 51, whether viewed from the up-down direction, the front-back direction (length direction), or the left-right direction (width direction). Therefore, the strength of the first protruding end portion 18 is improved.

[0125] Finally, from Fig. 6A , 6B The left and right half parts 10 are connected by the first protruding end 18 at both ends in the longitudinal direction, and the remaining terminal strip 68 and the accessory strip 58 are cut away. Figure 1 The first connector 1 is shown.

[0126] Next, the configuration of the second connector 101 forming a connector pair with the first connector 1 and the operation of fitting the first connector 1 and the second connector 101 will be described.

[0127] Fig. 91 is a perspective view showing a state of the first connector and the second connector just before being fitted together when viewed from the first connector side according to the present embodiment.

[0128] The second connector 101 of the present embodiment as a docking connector has a second base 111, and the second base 111 is integrally formed of an insulating material such as a synthetic resin as a docking connector body. As shown in the figure, the second base 111 is a roughly rectangular parallelepiped having a thick plate shape that is roughly rectangular. On the side of the second base 111 where the first connector 1 is embedded (i.e., the mating surface 111a side (Z-axis negative direction side)), a roughly rectangular recess 112 surrounded by the first base 11 is formed. The second convex portion 113 as an island portion that is mated with the groove portion 13 is formed integrally with the second base 111 in the recess 112, and the side wall portion 114 extending parallel to the second convex portion 113 is formed integrally with the second base 111 on both sides of the second convex portion 113.

[0129] The second convex portion 113 and the side wall portion 114 protrude upward (in the negative direction of the Z axis) from the bottom surface of the concave portion 112 and extend in the longitudinal direction of the second connector 101. Thus, a groove portion 112a, which is an elongated concave portion extending in the longitudinal direction (in the X axis direction) of the second connector 101, is formed on each side of the second convex portion 113 as a part of the concave portion 112.

[0130] A second terminal receiving groove cavity 115a in the shape of a groove for receiving the second terminal 161 is formed on the side surfaces on both sides of the second protrusion 113 and the side surfaces on the inner side of the side wall portion 114. In addition, a second terminal receiving hole cavity 115b in the shape of a hole for receiving the second terminal 161 is formed on the second protrusion 113 and the side wall portion 114. Moreover, since the second terminal receiving groove cavity 115a and the second terminal receiving hole cavity 115b are connected and integrated with each other on the bottom surface of the groove portion 112a, when the second terminal receiving groove cavity 115a and the second terminal receiving hole cavity 115b are collectively described, they are described as the second terminal receiving cavity 115. The second terminal receiving cavity 115 is arranged in a number corresponding to the first terminal 61 and at a pitch corresponding to the first terminal 61.

[0131] The second terminal 161 is a component integrally formed by applying processing such as stamping to a conductive metal plate, and includes: a body portion (not shown); a tail portion 162 connected to the lower end of the body portion; a connecting portion extending from the vicinity of the lower end of the body portion in the width direction (Y-axis direction) of the second connector 101; and a contact portion 165 extending upward (Z-axis negative direction) from the connecting portion. Preferably, a contact convex portion 165a protruding toward the body portion is formed near the end of the contact portion 165.

[0132] The main body portion is the portion that is pressed into and retained in the second terminal receiving cavity 115b. In addition, the tail portion 162 is bent and connected to the lower end of the main body portion, extends in the width direction of the second base 111, and is connected to the connection pad (the connection pad is connected to the conductive trace on the second substrate) by welding or the like. It is noted that the conductive trace is usually a signal line. In addition, the contact portion 165 is the portion that contacts the first terminal 61 of the first connector 1 when the first connector 1 is mated with the second connector 101. Preferably, the contact protrusion 165a engages with the contact recess 65a formed on the contact portion 65 of the first terminal 61.

[0133] The second terminal 161 is inserted into the second terminal receiving cavity 115 from below the second base 111 and mounted on the second base 111. Thus, the body of the second terminal 161 is pressed into and held in the second terminal receiving cavity 115b, the contact portion 165 is received in the second terminal receiving groove cavity 115a and exposed to the groove portion 112a, and the lower surface of the tail portion 162 is exposed to the mounting surface 111b as the lower surface of the second base 111.

[0134] Furthermore, like the first terminals 61, the second terminals 161 mounted in each groove portion 112a are oriented so that the postures of the adjacent second terminals 161 are opposite to each other in the width direction of the groove portion 112a. Fig. 9 In the example shown, in the second terminal 161 installed in the groove portion 112a on the positive direction side of the Y axis, the second terminal 161 located at the front end (the positive direction end of the X axis) is oriented so that the tail portion 162 protrudes in the negative direction of the Y axis, and the second terminal 161 located at the second position at the front end is oriented so that the tail portion 162 protrudes in the positive direction of the Y axis. In this way, since the second terminals 161 are alternately oriented in opposite directions and installed in the groove portion 112a, the spacing of the tail portions 162 exposed on the mounting surface 111b on both sides of the groove portion 112a is twice the spacing of the second terminals 161. Therefore, the connection operation to the connection pad of the second substrate by welding or the like can be easily performed. The spacing of the contact portions 165 exposed in the groove portion 112a is also twice the spacing of the second terminals 161.

[0135] The second protruding end portions 121 as the mating guide portions are respectively provided at both ends in the length direction of the second base 111. A mating recess 122 as a part of the above-mentioned recess 112 is formed on each second protruding end portion 121. The mating recess 122 is a substantially rectangular recess connected to both ends in the length direction of each recess portion 112a. In the state where the first connector 1 and the second connector 101 are mated, the first protruding end portion 18 of the first connector 1 is inserted into the mating recess 122. The second reinforcing accessory 151 as a docking accessory is mounted on the second protruding end portion 121. Note that the second reinforcing accessory 151 is integrated with the second base 111 by insert molding.

[0136] The second reinforcing fitting 151 is a component integrally formed by applying processing such as stamping and bending to a metal plate, and includes: a second body portion 152 extending in the width direction of the second base 111; a side cover portion 153 connected to the left and right ends of the second body portion 152; a contact side portion 154 provided on the left and right inner walls of the fitting recess 122; and a tail portion 156 connected to the lower end of the second body portion 152. The tail portion 156 extends outward in the length direction of the second connector 101, and is connected and fixed to a connection pad (not shown) exposed on the surface of the second substrate by welding or the like. In addition, for example, the connection pad is preferably connected to a conductive trace as a power line.

[0137] Next, the fitting operation of the first connector 1 and the second connector 101 having the above-described configuration will be described.

[0138] Here, the first connector 1 is mounted on the surface of the first substrate by connecting the tail 62 of the first terminal 61 to a connection pad connected to a conductive trace on the first substrate not shown by soldering, etc., and connecting the tail 52a of the first reinforcing fitting 51 to a connection pad connected to a conductive trace on the first substrate not shown by soldering, etc. It is assumed that the conductive trace connected to the connection pad to which the tail 62 of the first terminal 61 is connected is a signal line, and the conductive trace connected to the connection pad to which the tail 52a of the first reinforcing fitting 51 is connected is a power line.

[0139] Likewise, the second connector 101 is mounted on the surface of the second substrate by connecting the tail 162 of the second terminal 161 to a connection pad connected to a conductive trace on the second substrate not shown by soldering or the like, and connecting the tail 156 of the second reinforcing fitting 151 to a connection pad connected to a conductive trace on the second substrate not shown by soldering or the like. It is assumed that the conductive trace connected to the connection pad to which the tail 162 of the second terminal 161 is connected is a signal line, and the conductive trace connected to the connection pad to which the tail 156 of the second reinforcing fitting 151 is connected is a power line.

[0140] First, the operator makes the mating surface 12a of the first protrusion 12 (the mating surface 12a is the mating surface of the first base 11 of the first connector 1) and the mating surface 111a of the second base 111 of the second connector 101 face each other, and when the position of the first protrusion 12 of the first connector 1 is consistent with the position of the corresponding groove portion 112a of the second connector 101 and the position of the first protruding end portion 18 of the first connector 1 is consistent with the position of the corresponding mating recess 122 of the second connector 101, the alignment between the first connector 1 and the second connector 101 is completed.

[0141] In this state, when the first connector 1 and / or the second connector 101 moves in a direction approaching the mating side (i.e., the mating direction), the first convex portion 12 and the first protruding end portion 18 of the first connector 1 are inserted into the groove portion 112a and the mating recess 122 of the second connector 101. This completes the mating of the first connector 1 and the second connector 101. Then, the first terminal 61 is connected to the second terminal 161.

[0142] Next, a modified example of the first connector 1 will be described.

[0143] Fig.10 1 is an exploded view showing the left half of a modification of the first connector according to the present embodiment.

[0144] In the illustrated modification, the first terminal 61 does not include the body portion 63, but has: a contact portion 65 extending in the up-down direction; a tail portion 62 bent approximately 90 degrees and connected to the lower end of the contact portion 65; and an upper end portion 64 bent approximately 90 degrees and connected to the upper end of the contact portion 65. Note that an embedded portion 64a bent approximately 90 degrees and extending downward is connected to the distal end of the upper end portion 64. The embedded portion 64a is a portion embedded downward in the first protrusion 12 from the fitting surface 12a.

[0145] exist Figure 2 In the first terminal 61 shown in FIG. 1 , the tail portion 62 extends in a direction opposite to the direction in which the contact portion 65 faces, but Fig.10 In the first terminal 61 of the modified example shown, the tail portion 62 extends in the same direction as the direction facing the contact portion 65. Therefore, it is easy to hold the terminal strip 68 connected to the end of the tail portion 62 via the elongated connecting arm 68a and set the plurality of first terminals 61 in the primary molding die from both sides in an alternating manner in opposite directions.

[0146] Note that in Fig.10 The other structures, operations and effects of the first terminal 61 of the modified example are similar to those of Figure 2 The first terminal 61 shown in the figure is the same as that in the figure, and thus the description thereof is omitted.

[0147] As described above, in this embodiment, the first connector 1 includes: half bodies 10, each of which includes a first base 11 and a plurality of first terminals 61 mounted on the first base 11; first protruding end portions 18, which make the first bases 11 of each half body 10 butt against each other and are formed at both ends of the first base 11; and first reinforcing fittings 51 mounted on the first protruding end portions 18. Moreover, each first base 11 is a component integrated with the first terminal 61 by the first insert molding, and includes: a first convex portion 12, which extends in the length direction of the first base 11 and holds the first terminal 61; an extended end portion 14, which is connected to both ends of the length direction of the first convex portion 12; and an embedded portion 15, which extends from the extended end portion 14. The first protruding end portion 18 includes a covering portion 16, which covers at least a portion of the extended end portion 14 of each first base 11 and the entire embedded portion 15, and the covering portion 16 is a component integrated with the extended end portion 14, the embedded portion 15 and the first reinforcing fitting 51 by the second insert molding.

[0148] This can reduce the intervals between the first protrusions 12 of the first base 11 on which the plurality of first terminals 61 are mounted, and can reduce the size of the first connector 1. In addition, the first connector 1 can be easily manufactured and its reliability can be improved.

[0149] The first reinforcing fitting 51 includes: an upper plate 54 extending in the width direction of the first base 11; a pair of left and right legs 55 connected to the left and right side edges of the upper plate 54 and extending downward; and an end wall outer cover 52 and an end wall inner cover 53 connected to the front and rear side edges of the upper plate 54 and extending downward. The embedded portion 15 is provided so as to overlap at least partially with the upper plate 54, the legs 55, the end wall outer cover 52 and the end wall inner cover 53 when viewed from the top and bottom, front and back, and left and right directions. Thus, the embedded portion 15 of the left half body 10A is firmly connected to the embedded portion 15 of the right half body 10B through the cover 16 integrated with the first reinforcing fitting 51, thereby reliably forming the first protruding end 18 and reliably connecting the left half body 10A and the right half body 10B.

[0150] Furthermore, the embedded portion 15 of each first base 11 includes a parallel inner side surface 15c1 extending in the longitudinal direction of the first base 11 and facing the embedded portion 15 of the other first base 11. The distance L2 between the mutually facing parallel inner side surfaces 15c1 is smaller than the width L1 of the end wall inner surface covering portion 53 of the first reinforcing fitting 51 arranged to face the gap between the mutually facing parallel inner side surfaces 15c1. Therefore, when viewed from the front-rear direction, the boundary between the parallel inner side surface 15c1 of the embedded portion 15 formed by the first insert molding and the covering portion 16 formed by the second insert molding overlaps with the end wall inner surface covering portion 53, and therefore, is difficult to separate, increasing the strength of the first protruding end portion 18.

[0151] In addition, the end wall inner surface covering portion 53 is arranged to face the inclined inner surface 15c2, the inclined inner surface 15c2 is connected to each of the parallel inner surfaces 15c1 facing each other, the inclined inner surface 15c2 of the embedded portion 15 is inclined relative to the length direction of the first base 11, and there is a gap between the end wall inner surface covering portion 53 and the inclined inner surface 15c2.

[0152] Furthermore, the embedded portion 15 of each first base 11 includes an outer side surface 15b extending in the length direction of the first base 11 and facing the leg portion 55 of the first reinforcing fitting 51, and the length L4 of the outer side surface 15b is smaller than the length L3 of the leg portion 55. Therefore, when viewed from the left and right direction, the boundary between the outer side surface 15b of the embedded portion 15 formed by the first insert molding and the covering portion 16 formed by the second insert molding is covered by the leg portion 55, and therefore, is difficult to separate, and the strength of the first protruding end portion 18 is increased.

[0153] Furthermore, the extended end portion 14 of each first base 11 is inclined inwardly in the width direction of the first connector 1 and extends from both ends in the length direction of the first protrusion 12, and the width of the first protruding end portion 18 is smaller than the width of the first connector 1. In this manner, the width of the first protruding end portion 18 can be smaller than the width of the first connector 1, and therefore, when the first connector 1 is mated with the second connector 101, mating can be achieved even when the contact side portions 154 are provided on the left and right inner walls of the mating recess 122 of the second base 111 that allows the first protruding end portion 18 to be inserted and the width of the mating recess 122 is substantially reduced.

[0154] It is noted that the disclosure of this specification describes features related to preferred and exemplary embodiments. By summarizing the disclosure of this specification, those skilled in the art can naturally think of various other embodiments, modifications and variations within the scope and spirit of the appended claims. For example, the staggered arrangement of multiple terminals does not have to be regular. In addition, the configuration of the terminals on the left and right half bodies does not have to be the same. In addition, the left and right half bodies do not have to be axisymmetric.
