Description

[Technical field]

[0001] The present disclosure relates to a connector and an electronic device. [Background technology]

[0002] Conventionally, there has been widely known a technology relating to a connector module including a connector and a connection object mounted on different circuit boards for electrically connecting these circuit boards. For example, Patent Document 1 discloses a connector that can prevent damage to an island-shaped portion, etc., even when mated with a mating connector in a misaligned state.

[0003] In recent years, there has been a demand for electronic devices, including mobile devices, to be lighter, thinner, shorter, and smaller, and there has also been a demand for connectors mounted inside the electronic devices to be smaller and lower in height. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6498622 Summary of the Invention [Problem to be solved by the invention]

[0005] When a connector is made small and low-profile, the parts constituting the connector, such as the metal fittings and the insulator, are easily crushed or damaged, for example, by contacting the connection object during the process of fitting the connection object. For example, in the connector disclosed in Patent Document 1, reinforcing members are arranged from the outside on the upper surface of the mating convex portion of the insulator, i.e., the corners of the island-shaped portion, and on the side surfaces along the short direction of the connector, but no reinforcing members are arranged from the outside on the side surfaces along the long direction of the connector. Therefore, a part of the insulator is exposed at the corners of the mating convex portion, and protection is insufficient. This may cause problems such as scraping of the insulator due to contact with the connection object during the fitting and removal operations of the connector and the connection object.

[0006] In view of the above problems, an object of the present disclosure is to provide a connector and electronic device that have improved robustness even when made small and low-profile. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. In the following description, the directions of front, back, left, right, and up and down are based on the directions of the arrows in the drawings. The directions of the arrows are consistent between different drawings in Figures 1 to 8 and Figures 10 to 12. In some drawings, circuit boards CB1 and CB2, which will be described later, are omitted for the purpose of simplifying the illustration.

[0012] Fig. 1 is an external perspective view showing, as viewed from above, a connector module 1 in a state in which a connector 10 according to one embodiment and a connection object 50 are connected to each other. Fig. 2 is an external perspective view showing, as viewed from above, the connector module 1 in a state in which the connector 10 according to one embodiment and a connection object 50 are separated from each other.

[0013] 2, the connector module 1 has a connector 10 and a connection object 50 that are connectable to each other. The connector 10 has a first insulator 20 and a first contact 30 attached to the first insulator 20. The connector 10 has a first metal fitting 40a and a second metal fitting 40b attached to the first insulator 20.

[0014] The connection object 50 is connectable to the connector 10. The connection object 50 has a second insulator 60 that fits with the first insulator 20 in a connected state in which the connector 10 and the connection object 50 are connected. The connection object 50 has a second contact 70 attached to the second insulator 60. The second contact 70 comes into contact with the first contact 30 in a fitted state in which the first insulator 20 and the second insulator 60 are fitted together. The connection object 50 has a metal fitting 80 attached to the second insulator 60. The metal fitting 80 comes into contact with the first metal fitting 40a and the second metal fitting 40b in the fitted state. At this time, the second metal fitting 40b is elastically deformed.

[0015] In the following, for example, the connector 10 according to one embodiment will be described as a receptacle connector, and the connection object 50 will be described as a plug connector. That is, in a mated state in which the first insulator 20 and the second insulator 60 are mated with each other, the connector 10 in which the first contacts 30 elastically deform will be described as a receptacle connector, and the connection object 50 in which the second contacts 70 do not elastically deform will be described as a plug connector. The types of the connector 10 and the connection object 50 are not limited to these. For example, the connector 10 may play the role of a plug connector, and the connection object 50 may play the role of a receptacle connector.

[0016] The connection object 50 is not limited to the above and may be any object other than a plug connector and a receptacle connector. For example, the connection object 50 may be a flexible printed circuit board (FPC), a flexible flat cable, a rigid board, or a card edge of any circuit board.

[0017] In the following description, the connector 10 and the connection object 50 are described as being mounted on circuit boards CB1 and CB2, respectively. In a connected state in which the connector 10 and the connection object 50 are connected to each other, the connector 10 and the connection object 50 electrically connect the circuit boards CB1 and CB2. The circuit boards CB1 and CB2 may be rigid boards or any other circuit boards. For example, at least one of the circuit boards CB1 and CB2 may be an FPC.

[0018] In the following description, the connector 10 and the connection object 50 are connected to each other in a direction perpendicular to the circuit boards CB1 and CB2. That is, the connector 10 and the connection object 50 are connected to each other along the up-down direction, as an example. The connection method is not limited to this. The connector 10 and the connection object 50 may be connected to each other in a direction parallel to the circuit boards CB1 and CB2, or may be connected to each other such that one is perpendicular to the circuit board on which they are mounted and the other is parallel to the circuit board on which they are mounted.

[0019] The "longitudinal direction" described in the claims corresponds, for example, to the left-right direction. The "short direction" corresponds, for example, to the front-rear direction. The "mating side" corresponds, for example, to the upper side. The "side opposite to the mating side" corresponds, for example, to the lower side. The "circuit board CB1 side" corresponds, for example, to the lower side. The "first surface" corresponds, for example, to the top surface. The "second surface" corresponds, for example, to the rear surface. The "third surface" corresponds, for example, to the front surface. The "fourth surface" corresponds, for example, to a side surface in the left-right direction. The "first plane" corresponds, for example, to the top surface. The "second plane" corresponds, for example, to the rear surface. The "third plane" corresponds, for example, to the front surface. The "fourth plane" corresponds, for example, to a side surface in the left-right direction.

[0020] Fig. 3 is an external perspective view showing the connector 10 alone from above in Fig. 1. As an example, the connector 10 is obtained by press-fitting the first contact 30 and the second metal fitting 40b into the first insulator 20, and integrally molding the first metal fitting 40a and the first insulator 20 by insert molding.

[0021] Fig. 4 is an external perspective view showing an exploded top view of the connector 10 shown in Fig. 3. In reality, the first metal fitting 40a and the first insulator 20 are integrally molded by insert molding, but in Fig. 4, the first insulator 20 and the first metal fitting 40a are virtually separated and shown as separate units to facilitate understanding.

[0022] The first insulator 20 constituting the connector 10 is formed of an insulating and heat-resistant synthetic resin material. The first insulator 20 extends in a plate shape in the left-right direction. The first insulator 20 has a bottom plate portion 21 constituting the lower portion. The first insulator 20 has a fitting protrusion 22 protruding upward from the center of the bottom plate portion 21 in the front-rear and left-right directions. The first insulator 20 has an outer peripheral wall 23 surrounding the fitting protrusion 22. The outer peripheral wall 23 surrounds the fitting protrusion 22 from four directions, front-rear and left-right. The outer peripheral wall 23 has short side walls 23a and long side walls 23b. The short side walls 23a extend in the front-rear direction. The long side walls 23b extend in the left-right direction.

The first contacts 30 are mounted in the first contact mounting groove 24. A plurality of first contact mounting grooves 24 are formed corresponding to the number of first contacts 30. The plurality of first contact mounting grooves 24 are arranged along the arrangement direction of the first contacts 30.

[0024] The first insulator 20 has a first metal fitting holding portion 25 that extends from the left-right end of the fitting protrusion 22 through the bottom plate portion 21 to the short wall 23a. As shown in FIG. 5 described later, the first metal fitting holding portion 25 has a first portion 251 recessed at the left-right end of the fitting protrusion 22. The first metal fitting holding portion 25 has a second portion 252 formed to penetrate the inside of the bottom plate portion 21. The first metal fitting holding portion 25 has a third portion 253 recessed in the lower surface of the short wall 23a. The first metal fitting 40a is attached to the first metal fitting holding portion 25. The first metal fitting holding portion 25 extends in the left-right direction to connect the fitting protrusion 22 and the short wall 23a.

[0025] The first insulator 20 has second metal fitting attachment portions 26 formed across the left and right ends of the long side walls 23b and the short side walls 23a. A second metal fitting 40b is attached to the second metal fitting attachment portions 26.

[0026] The second metal fitting mounting portion 26 has a first wall portion 261a formed below the center of the short wall 23a in the front-rear direction and protruding outward in the left-right direction.

The second metal fitting mounting portion 26 has a third wall portion 262 formed from the short wall 23a to the long wall 23b at the lower end of the corner of the first insulator 20. The second metal fitting mounting portion 26 has a fourth wall portion 263 formed on the long wall 23b, spaced apart from the third wall portion 262 in the left-right direction. The first wall portion 261a, the second wall portion 261b, the third wall portion 262, and the fourth wall portion 263 form the outermost rectangular shape of the first insulator 20 in the front-rear and left-right directions.

[0027] The second fitting attachment portion 26 has a first attachment groove 264 formed between the first wall portion 261a and the second wall portion 261b and on the outer side of the second wall portion 261b in the front-to-rear direction. The second fitting attachment portion 26 has a second attachment groove 265 formed between the third wall portion 262 and the fourth wall portion 263.

[0028] Fig. 5 is an enlarged view of the area V enclosed by the two-dot chain line in Fig. 3, showing only the first insulator 20. With reference to Fig. 5, the configuration of the fitting protrusion 22 in the first portion 251 of the first metal fitting holding portion 25 of the first insulator 20 will be described in more detail.

[0029] As shown in FIG. 5, the fitting protrusion 22 of the first insulator 20 has a first surface 221 constituting an end surface on the fitting side in the first portion 251 of the first metal fitting holding portion 25. The fitting protrusion 22 has a second surface 222 extending from a rear end edge of the first surface 221 along the longitudinal direction of the connector 10 toward the opposite side to the fitting side. The fitting protrusion 22 has a third surface 223 extending from a front end edge of the first surface 221 along the longitudinal direction of the connector 10 toward the opposite side to the fitting side. The fitting protrusion 22 has a fourth surface 224 extending from a left-right edge of the first surface 221 along the lateral direction of the connector 10 toward the opposite side to the fitting side. Each of the first surface 221, the second surface 222, the third surface 223, and the fourth surface 224 is configured as a flat surface.

[0030] The fitting protrusion 22 has a first intersection R1 where the first surface 221, the second surface 222, and the fourth surface 224 intersect. The first intersection R1 is located at a rear corner of the fitting protrusion 22, and includes one intersection point where the three surfaces, the first surface 221, the second surface 222, and the fourth surface 224, intersect, and a region located in the vicinity of the intersection point on each of the three surfaces, the first surface 221, the second surface 222, and the fourth surface 224.

[0031] The fitting protrusion 22 has a second intersection R2 where the first surface 221, the third surface 223, and the fourth surface 224 intersect. The second intersection R2 is located at a front corner of the fitting protrusion 22, and includes one intersection point where the three surfaces, the first surface 221, the third surface 223, and the fourth surface 224, intersect, and a region located in the vicinity of the intersection point on each of the three surfaces, the first surface 221, the third surface 223, and the fourth surface 224.

[0032] The fitting protrusion 22 has a first intersection line L1 between the first surface 221 and the second surface 222. The fitting protrusion 22 has a second intersection line L2 between the first surface 221 and the third surface 223. The fitting protrusion 22 has a third intersection line L3 between the second surface 222 and the fourth surface 224. The fitting protrusion 22 has a fourth intersection line L4 between the third surface 223 and the fourth surface 224. The fitting protrusion 22 has a fifth intersection line L5 between the first surface 221 and the fourth surface 224. Each of the first intersection line L1, the second intersection line L2, the third intersection line L3, the fourth intersection line L4, and the fifth intersection line L5 is configured as a straight line.

[0033] The first contact 30 is formed, for example, by stamping a thin plate of spring-elastic copper alloy or Corson copper alloy containing phosphor bronze, beryllium copper, or titanium copper into the shape shown in Fig. 4. The surface of the first contact 30 is plated with gold, tin, or the like after forming a base with nickel plating.

[0034] The first contact 30 has a mounting portion 31 that extends outward in an L-shape in the front-rear direction. The first contact 30 has a locking portion 32 that continues upward from the upper end of the mounting portion 31. The locking portion 32 is formed to be wider in the left-right direction than the mounting portion 31. The first contact 30 has a curved portion 33 that protrudes upward from the locking portion 32 in a U-shape.

[0035] The first contact 30 has a resilient contact piece 34 formed in an S-shape and continuing from the curved portion 33. The first contact 30 has a resilient contact portion 35 formed facing outward in the front-rear direction at the bent portion of the tip of the resilient contact piece 34. The first contact 30 has a contact portion 36 protruding from the curved portion 33 at a position opposing the resilient contact portion 35 in the front-rear direction.

[0036] The first metal fitting 40a is formed by forming a thin plate of any metal material into the shape shown in FIG. 4 using a progressive die (stamping). The first metal fitting 40a is formed so that its overall shape is crank-shaped. More specifically, the claw portion 42a, the first base portion 41a, and the second base portion 43a described later are integrally formed so as to be crank-shaped as a whole. Similarly, the first base portion 41a and the second base portion 43a are integrally formed so as to be crank-shaped as a whole. The first metal fitting 40a is processed by a process including drawing so that the surfaces of the first base portion 41a in the front-rear, left-right, and upper directions are continuous without gaps. This is not limited to this, and the processing method of the first metal fitting 40a may include only processes based on punching and bending in the plate thickness direction without drawing.

[0037] The first metal fitting 40a has a first base portion 41a. The first base portion 41a extends from the bottom to the top so as to be inclined inward in the left-right direction, and its upper end portion is bent toward one side in the left-right direction. The first base portion 41a connects a second base portion 43a (described later) and a claw portion 42a.

[0038] The first metal fitting 40a has a claw portion 42a extending further to one side in the left-right direction from a portion extending to one side in the left-right direction in the first base portion 41a. The claw portion 42a is formed in an L-shape. For example, a tip 42a1 of the claw portion 42a is bent downward at an end portion on one side of the claw portion 42a. In the front-rear direction, the claw portion 42a is narrower than other portions of the first metal fitting 40a. For example, the front-rear width of the claw portion 42a is narrower than the front-rear width of the first base portion 41a connected to the claw portion 42a. For example, the front-rear width of the claw portion 42a is narrower than the front-rear width of each of the second base portion 43a and the wide portion 44a described later.

[0039] The first metal fitting 40a has a second base portion 43a extending linearly from a lower end of the first base portion 41a to the other side in the left-right direction. The width of the second base portion 43a in the front-rear direction is narrower than the width of the first base portion 41a connected to the second base portion 43a in the front-rear direction.

[0040] The first metal fitting 40a has a wide portion 44a formed to be wider in the front-rear direction than other portions of the second base portion 43a. The wide portion 44a protrudes symmetrically from the center of the second base portion 43a in the left-right direction to both sides in the front-rear direction. As shown in FIG. 6 described later, the first metal fitting 40a has a mounting portion 45a. The mounting portion 45a includes, for example, a bottom surface on the circuit board CB1 side at an end portion in the longitudinal direction of the second base portion 43a. The mounting portion 45a is not limited to this, and may include a thickness portion along the up-down direction exposed from the bottom plate portion 21 of the first insulator 20 in the second base portion 43a in addition to the bottom surface of the second base portion 43a.

[0041] 4, the first metal fitting 40a has a contact portion 46a adjacent to the first base portion 41a on the outside in the left-right direction at the second base portion 43a. The second base portion 43a is formed such that a central portion including a wide portion 44a is inclined obliquely upward from the mounting portion 45a toward the inside in the left-right direction and then becomes horizontal again at the contact portion 46a.

[0042] Fig. 6 is an enlarged view showing only the first fitting 40a by enlarging the area V enclosed by the two-dot chain line in Fig. 3. With reference to Fig. 6, the configuration of the first base portion 41a of the first fitting 40a will be described in more detail while comparing it with each component of the fitting protrusion 22 in Fig. 5.

[0043] The first fitting 40a has a first end 41a1 disposed across the first surface 221, the second surface 222, and the fourth surface 224 at a first intersection R1 where the first surface 221, the second surface 222, and the fourth surface 224 of the fitting protrusion 22 intersect. The first end 41a1 includes a predetermined region of a rear corner of the first base portion 41a, and is generally formed of a curved surface. The first end 41a1 corresponds to an upper rear corner of the first fitting 40a.

[0044] The first fitting 40a has a second end 41a2 disposed across the first surface 221, the third surface 223, and the fourth surface 224 at a second intersection R2 where the first surface 221, the third surface 223, and the fourth surface 224 of the fitting protrusion 22 intersect. The second end 41a2 includes a predetermined region of a front corner of the first base portion 41a, and is generally formed of a curved surface. The second end 41a2 corresponds to an upper front corner of the first fitting 40a.

[0045] The first metal fitting 40a has a first extending portion 41a3 extending from the first end portion 41a1 in the longitudinal direction across the adjacent region of the first surface 221 and the second surface 222 along a first intersection line L1 between the first surface 221 and the second surface 222. The first extending portion 41a3 is formed so that its cross section is L-shaped when viewed from the left-right side.

The second extending portion 41a4 is formed so that its cross section is L-shaped when viewed from the left-right side. The second extending portion 41a4 is formed so as to bend from the top surface of the first base portion 41a to the front surface.

[0047] The first metal fitting 40a has a third extension portion 41a5 extending from the first end 41a1 toward the opposite side to the fitting side across the adjacent region of the second surface 222 and the fourth surface 224 along a third intersection line L3 between the second surface 222 and the fourth surface 224. The third extension portion 41a5 is formed so that its cross section is L-shaped in a side view when viewed from above. The third extension portion 41a5 is formed so as to bend from the left and right side surfaces of the first base portion 41a to the rear surface.

[0048] The first metal fitting 40a has a fourth extension portion 41a6 extending from the second end portion 41a2 toward the opposite side to the fitting side across the adjacent region of the third surface 223 and the fourth surface 224 along a fourth intersection line L4 between the third surface 223 and the fourth surface 224. The fourth extension portion 41a6 is formed so that its cross section is L-shaped in a side view when viewed from above. The fourth extension portion 41a6 is formed so as to bend from the side surfaces in the left and right direction of the first base portion 41a to the front surface.

[0049] The first metal fitting 40a has a fifth extension portion 41a7 extending between the first end 41a1 and the second end 41a2 across the adjacent region of the first surface 221 and the fourth surface 224 along a fifth intersection line L5 between the first surface 221 and the fourth surface 224. The fifth extension portion 41a7 is formed so that its cross section is L-shaped when viewed from the side in the front-rear direction. The fifth extension portion 41a7 is formed so as to bend from the top surface of the first base portion 41a to the side surfaces in the left-right direction.

[0050] The first fitting 40a has a first plane S1 arranged along the first surface 221, a second plane S2 arranged along the second surface 222, a third plane S3 arranged along the third surface 223, and a fourth plane S4 arranged along the fourth surface 224.

[0051] The first plane S1 forms the upper surface of the first fitting 40a along the front edge of the first extending portion 41a3, the left-right edge of the fifth extending portion 41a7, and the rear edge of the second extending portion 41a4. The second plane S2 forms the rear surface of the first fitting 40a along the lower edge of the first extending portion 41a3 and the left-right edge of the third extending portion 41a5.

[0052] The third plane S3 forms the front surface of the first metal fitting 40a along the lower edge of the second extending portion 41a4 and the left-right edge of the fourth extending portion 41a6. The fourth plane S4 forms the left-right side surface of the first metal fitting 40a along the front edge of the third extending portion 41a5, the lower edge of the fifth extending portion 41a7, and the rear edge of the fourth extending portion 41a6.

[0053] The first fitting 40a continuously covers the first surface 221, the second surface 222, the third surface 223, and the fourth surface 224, as well as all of the intersection lines, with surfaces perpendicular to the plate thickness direction at the longitudinal end of the fitting protrusion 22. The first fitting 40a is formed such that the first plane S1, the second plane S2, the third plane S3, and the fourth plane S4 are smoothly connected by the ends and extensions at the first base portion 41a, with no gaps between the planes. This shape is achieved by drawing.

[0054] The second metal fitting 40b is formed by using a progressive die (stamping) to form a thin plate of any metal material into the shape shown in Fig. 4. The method of processing the second metal fitting 40b includes a step of bending the plate in the thickness direction after punching.

[0055] The second metal fitting 40b has a first base 41b extending in the front-rear direction. The second metal fitting 40b has a second base 42b extending from each of both ends of the first base 41b in the front-rear direction to one side in the left-right direction. The second metal fitting 40b has a protruding piece 43b extending downward in a straight line at each of the front and rear parts of the first base 41b and extending outward in the left-right direction at the lower end. A recess is formed by the opposing edges of the pair of protruding pieces 43b separated from each other in the front-rear direction and the lower edge of the first base 41b. The second metal fitting 40b has a first mounting part 44b located at the lower end of the protruding piece 43b. The second metal fitting 40b has a locking part 45b1 including a part of the protruding piece 43b formed wider in the front-rear direction than the other part and another protruding piece extending downward in a straight line from the first base 41b on the outer side of the protruding piece 43b in the front-rear direction.

[0056] The second metal fitting 40b has a curved portion 46b that extends in a U-shape on the inside of the second metal fitting 40b to cover substantially the entire first base portion 41b and the other end of the second base portion 42b in the left-right direction. The second metal fitting 40b has an inner edge portion 47b that is formed continuously without gaps in the left-right and front-rear directions on the inside of the curved portion 46b.

[0057] The second metal fitting 40b has a U-shaped contact piece 48b formed at one end of the second base 42b in the left-right direction. The part of the contact piece 48b that extends inward in the front-rear direction has spring elasticity. The second metal fitting 40b has a second mounting portion 49b located at the lower end of the outer side in the front-rear direction of the second base 42b. The second mounting portion 49b extends over substantially the entire left-right direction of the second base 42b. The second metal fitting 40b has a locking portion 45b2 formed adjacent to the second mounting portion 49b above. The locking portion 45b2 is formed wider in the left-right direction than other portions of the second base 42b. The locking portion 45b2 protrudes symmetrically on both sides in the left-right direction of the second base 42b.

[0058] Fig. 7 is an enlarged view of a portion V enclosed by a two-dot chain line in Fig. 3. Fig. 8 is an enlarged view of the connector 10 in Fig. 7 as seen from below.

[0059] The first contact 30 is press-fitted from below the first insulator 20. At this time, the locking portions 32 are locked to the inner wall surfaces in the left-right direction of the first contact mounting groove 24. As a result, the first contact 30 is held in the first contact mounting groove 24.

[0060] When the first contact 30 is held in the first contact mounting groove 24 of the first insulator 20, the elastic contact portion 35 and the contact portion 36 are exposed from the first contact mounting groove 24 between the fitting protrusion 22 and the longitudinal wall 23b. At this time, the elastic contact piece 34 is elastically deformable in the front-rear direction within the first contact mounting groove 24. The front-rear tip of the mounting portion 31 is at approximately the same front-rear position as the longitudinal wall 23b.

[0061] As shown in Figs. 7 and 8, the first metal fitting 40a and the second metal fitting 40b are different members. That is, the first metal fitting 40a and the second metal fitting 40b are separated from each other. The first metal fitting 40a and the second metal fitting 40b face each other in the left-right direction while separated from each other. The strengths of the first metal fitting 40a and the second metal fitting 40b are different from each other. That is, the strength of one of the first metal fitting 40a and the second metal fitting 40b is higher than the strength of the other. For example, the strength of the first metal fitting 40a may be higher than the strength of the second metal fitting 40b. For example, the strength of the material of the first metal fitting 40a may be higher than the strength of the material of the second metal fitting 40b. In this specification, "strength" includes, for example, tensile strength.

[0062] The material of the first metal fitting 40a may be different from the material of the second metal fitting 40b. For example, the material of the first metal fitting 40a may be stainless steel, and the material of the second metal fitting 40b may be phosphor bronze. Without being limited thereto, the material of the first metal fitting 40a and the material of the second metal fitting 40b may be selected from a group of candidate materials in any combination such that the strength of the first metal fitting 40a is higher than the strength of the second metal fitting 40b. In this specification, the "group of candidate materials" includes, for example, stainless steel, phosphor bronze, iron, Corson copper, titanium copper, beryllium copper, and aluminum.

[0063] The material of the first fitting 40a may be the same as the material of the second fitting 40b, so long as the strength of the first fitting 40a is higher than that of the second fitting 40b. For example, the strength of the first fitting 40a may be higher than that of the second fitting 40b even if they are made of the same material, such as phosphor bronze, by having different alloy numbers, type symbols, and tempers. For example, the strength of the first fitting 40a may be higher than that of the second fitting 40b even if they are made of the same material, such as phosphor bronze, by having the plate thickness of the first fitting 40a be greater than that of the second fitting 40b, as described below.

[0064] For example, the strength of the first contact 30 may be substantially the same as the strength of the second metal fitting 40b. The strength of the first metal fitting 40a may be higher than the strength of the first contact 30 in addition to the second metal fitting 40b. The material of the first metal fitting 40a, the material of the second metal fitting 40b, and the material of the first contact 30 may be selected from a group of candidate materials in any combination that satisfies the above-described strength relationship between the first metal fitting 40a, the second metal fitting 40b, and the first contact 30.

[0065] The pair of first metal fittings 40a are attached to both ends of the fitting protrusion 22 in the longitudinal direction of the connector 10. The first metal fittings 40a extend along the longitudinal direction of the connector 10 from the fitting protrusion 22 to the short wall 23a to which the second metal fitting 40b is attached.

[0066] For example, the first metal fitting 40a is molded integrally with the first metal fitting holding portion 25 of the first insulator 20 by insert molding. At this time, the first base portion 41a is molded integrally with the fitting protrusion 22 from the top surface to the side surface at the left and right ends of the fitting protrusion 22. For example, the first base portion 41a is molded integrally with the first portion 251 of the first metal fitting holding portion 25. The first base portion 41a covers the entire left and right ends of the fitting protrusion 22 from the outside.

[0067] More specifically, the first end 41a1 covers the first intersection R1. The second end 41a2 covers the second intersection R2. The first extension 41a3 covers the first intersection L1 and adjacent areas along the first intersection L1 on the first surface 221 and the second surface 222. The second extension 41a4 covers the second intersection L2 and adjacent areas along the second intersection L2 on the first surface 221 and the third surface 223. The third extension 41a5 covers the third intersection L3 and adjacent areas along the third intersection L3 on the second surface 222 and the fourth surface 224. The fourth extension 41a6 covers the fourth intersection L4 and adjacent areas along the fourth intersection L4 on the third surface 223 and the fourth surface 224. The fifth extension portion 41a7 covers the fifth intersection line L5 and adjacent regions along the fifth intersection line L5 on the first surface 221 and the fourth surface 224. The first plane S1, the second plane S2, the third plane S3, and the fourth plane S4 cover the first surface 221, the second surface 222, the third surface 223, and the fourth surface 224, respectively.

[0068] The first plane S1 of the first base portion 41a is flush with the upper surface of the fitting protrusion 22. The second plane S2 and the third plane S3 of the first base portion 41a are flush with the side surface of the fitting protrusion 22. Without being limited thereto, the first plane S1 of the first base portion 41a may not be flush with the upper surface of the fitting protrusion 22. For example, the first plane S1 of the first base portion 41a may be located lower than the upper surface of the fitting protrusion 22. The second plane S2 and the third plane S3 of the first base portion 41a may not be flush with the side surface of the fitting protrusion 22. For example, the second plane S2 and the third plane S3 of the first base portion 41a may be located inside the side surface of the fitting protrusion 22 in the left-right direction.

[0069] The claw portion 42a is integrally formed with the fitting protrusion 22 on the upper surface side of the fitting protrusion 22 such that a tip 42a1 of the claw portion 42a is embedded inside the fitting protrusion 22. The upper surface of the claw portion 42a is exposed from the first insulator 20. For example, the upper surface of the claw portion 42a is flush with the upper surface of the fitting protrusion 22. However, the present invention is not limited to this, and the upper surface of the claw portion 42a may be located lower than the upper surface of the fitting protrusion 22.

[0070] The second base portion 43a is molded integrally with the bottom plate portion 21 and the short wall 23a. A portion of the second base portion 43a except for its left-right tip is molded integrally with the second portion 252 of the first metal fitting holding portion 25. In this state, the contact portion 46a of the second base portion 43a is exposed upward from the bottom plate portion 21. The tip of the second base portion 43a including the mounting portion 45a is molded integrally with the third portion 253 of the first metal fitting holding portion 25. In this state, the tip of the second base portion 43a is exposed outward in the left-right direction from the first wall portion 261a of the short wall 23a.

[0071] When the first metal fitting 40a and the first insulator 20 are integrally molded by insert molding, the wide portion 44a is embedded inside the bottom plate portion 21. The second base portion 43a extends along the longitudinal direction of the connector 10. The second base portion 43a extends from the fitting protrusion 22 to the short wall 23a to which the second metal fitting 40b is attached. The lower surface of the portion including the mounting portion 45a at the left-right end of the second base portion 43a is exposed from the first insulator 20. For example, the lower surface of the second base portion 43a is located lower than the lower surface of the bottom plate portion 21.

[0072] The mounting portion 45a of the first fitting 40a, which is mounted on the circuit board CB1, includes the bottom surface of the second base portion 43a on the circuit board CB1 side. For example, the mounting portion 45a has a predetermined area in the front-rear and left-right directions on the lower surface of the second base portion 43a. The mounting portion 45a is located directly below the short wall 23a in the left-right direction.

[0073] For example, the second metal fitting 40b is press-fitted from above the first insulator 20. The second metal fitting 40b is attached to the outer peripheral wall 23 such that a recess formed by opposing edges of a pair of protruding pieces 43b spaced apart from each other in the front-rear direction and a lower edge of the first base portion 41b sandwiches the first wall portion 261a.

[0074] At this time, the locking portion 45b1 locks with the second wall portion 261b of the second metal fitting mounting portion 26 on the outer side in the left-right direction of the short wall 23a. The pair of protruding pieces 43b and the locking portion 45b1, which are spaced apart from each other in the front-to-rear direction, are attached to the first mounting groove 264. Similarly, the locking portion 45b2 locks with the third wall portion 262 and the fourth wall portion 263 of the second metal fitting mounting portion 26 on the outer side in the front-to-rear direction of the long wall 23b. The locking portion 45b2 is attached to the second mounting groove 265. As described above, the second metal fitting 40b is held by the second metal fitting mounting portion 26.

[0075] When the second metal fitting 40b is held by the second metal fitting attachment portion 26 of the first insulator 20, it covers the entire short wall 23a and the left and right ends of the long wall 23b. At this time, the second metal fitting 40b surrounds the second base portion 43a of the first metal fitting 40a from both the front and rear sides and the outside in the left and right directions. More specifically, the second base portion 42b of the second metal fitting 40b is disposed on both the front and rear sides of the second base portion 43a of the first metal fitting 40a. The first base portion 41b, the protruding piece 43b, and the curved portion 46b of the second metal fitting 40b are disposed so as to overlap the outer end portion of the second base portion 43a of the first metal fitting 40a in the left and right direction. In addition, the portion of the contact piece 48b that is disposed on the inner side in the front and rear direction and extends downward is elastically deformable in the front and rear direction.

[0076] The first mounting portion 44b is disposed along the outer surface of the short wall 23a in the left-right direction. The first mounting portion 44b extends downward from the lower end of the short wall 23a. The first mounting portion 44b is disposed on both sides of the second base portion 43a of the first metal fitting 40a in the short direction of the connector 10. That is, the pair of first mounting portions 44b are positioned so as to sandwich the second base portion 43a of the first metal fitting 40a from both sides in the front-rear direction. For example, the pair of first mounting portions 44b are disposed at positions symmetrical in the front-rear direction with respect to the second base portion 43a of the first metal fitting 40a.

[0077] The second mounting portion 49b is disposed along the outer surface of the longitudinal wall 23b in the front-rear direction. The second mounting portion 49b extends downward from the lower end of the longitudinal wall 23b. The second mounting portion 49b is disposed on both sides of the first metal fitting 40a in the short-side direction of the connector 10. That is, the pair of second mounting portions 49b are positioned so as to sandwich the second base portion 43a of the first metal fitting 40a from both sides in the front-rear direction. For example, the pair of second mounting portions 49b are disposed at positions symmetrical in the front-rear direction with respect to the mounting portion 45a formed on the second base portion 43a. The pair of second mounting portions 49b are disposed at substantially the same left-right positions as the mounting portion 45a and the wide portion 44a.

[0078] In the connector 10 having the above structure, the mounting portion 31 of the first contact 30 is soldered to the circuit pattern formed on the mounting surface of the circuit board CB1. The mounting portion 45a of the first metal fitting 40a and the first mounting portion 44b and the second mounting portion 49b of the second metal fitting 40b are soldered to the pattern formed on the mounting surface. By mounting each mounting portion on the circuit board CB1 in the above manner, the connector 10 is mounted on the circuit board CB1. Electronic components other than the connector 10, such as a CPU (Central Processing Unit), a controller, and a memory, are mounted on the mounting surface of the circuit board CB1.

[0079] Next, the configuration of the connection object 50 will be described mainly with reference to FIG.

[0080] Fig. 9 is an external perspective view showing the top view of the connection object 50 alone of Fig. 1. The connection object 50 is obtained, for example, by integrally molding the second contact 70 and the second insulator 60 by insert molding, and by press-fitting the metal fitting 80 into the second insulator 60 from above.

[0081] The second insulator 60 is a plate-like member extending in the left-right direction, which is injection-molded from an insulating and heat-resistant synthetic resin material. The second insulator 60 has a bottom plate portion 61 that forms the lower portion. The second insulator 60 has an annular outer peripheral wall 62 that protrudes upward along the outer periphery of the bottom plate portion 61 on the front-rear and left-right sides. The outer peripheral wall 62 has a short wall 62a and a long wall 62b. The short wall 62a extends in the front-rear direction. The long wall 62b extends in the left-right direction. The second insulator 60 has a fitting recess 63 that is surrounded by the outer peripheral wall 62 from four directions, namely, the front-rear, left-right, and right-left.

[0082] The second insulator 60 has a second contact holding portion 64 formed across the long wall 62b and the bottom plate portion 61. A second contact 70 is attached to the second contact holding portion 64. The second insulator 60 has a metal fitting holding portion 65 formed on the short wall 62a. A metal fitting 80 is attached to the metal fitting holding portion 65.

[0083] The second contact 70 is formed by stamping a thin plate of a copper alloy containing phosphor bronze, beryllium copper, or titanium copper, or a Corson copper alloy into the shape shown in the figure. The surface of the second contact 70 is plated with gold, tin, or the like after forming a base with nickel plating.

[0084] The second contact 70 has a mounting portion 71 that extends outward in the front-rear direction in an L-shape. The second contact 70 has a curved portion 72 that extends upward in a U-shape from the mounting portion 71. The second contact 70 has a pair of contact portions 73 that are configured to include side surfaces in the front-rear direction on both the front and rear sides of the curved portion 72.

[0085] The second contact 70 is molded integrally with the second contact holding portion 64 of the second insulator 60 by insert molding. At this time, the pair of contact portions 73 are arranged along both the front and rear sides of the longitudinal wall 62b, respectively. The mounting portion 71 extends outward in the front-rear direction through the bottom plate portion 61. The front-rear end of the mounting portion 71 is located outward in the front-rear direction from the longitudinal wall 62b.

[0086] The metal fitting 80 is made by forming a thin plate of any metal material into the shape shown in the figure using a progressive die (stamping). The method of processing the metal fitting 80 includes a step of bending the plate in the thickness direction after punching.

[0087] The metal fitting 80 has a base 81 formed on a flat plate. The metal fitting 80 has a first extending portion 82 extending in an L-shape from the outer end and inner end of the base 81 in the left-right direction toward the outside and inside in the left-right direction, respectively. The metal fitting 80 has a second extending portion 83 extending in an L-shape from each of both ends of the base 81 in the front-rear direction toward the outside in the front-rear direction. The metal fitting 80 has a contact portion 84 formed on the outer surface of the second extending portion 83 in the front-rear direction. The metal fitting 80 has a mounting portion 85 located at the lower end of each of the first extending portion 82 and the second extending portion 83 on the outside. The metal fitting 80 is attached to the second insulator 60 by engaging the first extending portion 82 and the second extending portion 83 with the metal fitting holding portion 65 of the second insulator 60.

[0088] In the connection object 50 having the above-mentioned structure, the mounting portion 71 of the second contact 70 is soldered to the circuit pattern formed on the mounting surface of the circuit board CB2. The mounting portion 85 of the metal fitting 80 is soldered to the pattern formed on the mounting surface. In this manner, the connection object 50 is mounted on the circuit board CB2. For example, an electronic component other than the connection object 50, such as a communication module, is mounted on the mounting surface of the circuit board CB2.

[0089] 10 to 12, a description will be given mainly of the configuration of the connector module 1 in a fitted state in which the connector 10 and the connection target 50 are connected and the first insulator 20 and the second insulator 60 are fitted together. Fig. 10 is a cross-sectional view taken along the arrow XX in Fig. 1.

[0090] For example, with the connection object 50 shown in Fig. 9 facing upside down, the connector 10 and the connection object 50 are opposed to each other in the up-down direction while their front-to-back and left-to-right positions are approximately aligned. Then, the connection object 50 is moved downward. As a result, the connector 10 and the connection object 50 are connected to each other, and the connected state of the connector module 1 is obtained. At this time, the mating convex portion 22 of the first insulator 20 and the mating concave portion 63 of the second insulator 60 are mated with each other.

[0091] In the mated state, the resilient contact portion 35 of the first contact 30 and the contact portion 73 of the second contact 70 come into contact, and the resilient contact piece 34, which has spring resilience, elastically deforms inward in the front-rear direction. In the mated state, the contact portion 36 of the first contact 30 and the contact portion 73 of the second contact 70 come into contact. The first contact 30 and the second contact 70 come into contact at two points on both the front and rear sides, by the resilient contact portion 35 and the contact portion 73, and the contact portion 36 and the contact portion 73.

[0092] FIG. 11 is a cross-sectional view taken along the line XI-XI in FIG.

[0093] In the mated state, the contact piece 48b of the second fitting 40b comes into contact with the contact portion 84 of the fitting 80. At this time, the contact piece 48b, which has spring elasticity, elastically deforms outward in the front-to-rear direction. The second fitting 40b and the fitting 80 come into contact with each other at two points on both the front and rear sides by the contact piece 48b and the contact portion 84.

[0094] An upper surface of the second base portion 43a contacts the base portion 81 of the metal fitting 80. More specifically, a contact portion 46a exposed upward from the second portion 252 of the bottom plate portion 21 of the second base portion 43a contacts the base portion 81 of the metal fitting 80.

[0095] FIG. 12 is a cross-sectional view taken along the line XII-XII of FIG.

[0096] In a mated state in which the connector 10 and the connection object 50 are mated with each other, the second metal fitting 40b is positioned to sandwich the metal fitting 80 of the connection object 50 together with the first metal fitting 40a. That is, the metal fitting 80 is positioned between the first metal fitting 40a and the second metal fitting 40b in the longitudinal direction of the connector 10. In the mated state, the second base portion 43a of the first metal fitting 40a and the base portion 81 of the metal fitting 80 are arranged to contact each other in the vertical direction. More specifically, the contact portion 46a of the second base portion 43a and the base portion 81 are arranged to contact each other in the vertical direction. In the mated state, the inner edge portion 47b of the curved portion 46b of the second metal fitting 40b and the first extension portion 82 on the outside of the metal fitting 80 are arranged to face each other in the horizontal direction.

[0097] The first metal fitting 40a overlaps along the arrangement direction with one of the first contacts 30 located at an end in the arrangement direction among the multiple first contacts 30 arranged along the arrangement direction parallel to the longitudinal direction of the connector 10. For example, as shown in Fig. 7, the claw portion 42a of the first metal fitting 40a overlaps along the arrangement direction with one of the first contacts 30 located at the end in the arrangement direction. For example, the left-right position of a part of the portion of the claw portion 42a extending in the left-right direction becomes the same as the left-right position of one of the first contacts 30.

[0098] 12, the tip 42a1 of the claw portion 42a of the first metal fitting 40a is located in the arrangement direction between one first contact 30 and another first contact 30 adjacent to the one first contact 30. For example, a part of the portion extending in the left-right direction of the claw portion 42a is also located between the one first contact 30 and the other first contact 30 in the arrangement direction, together with the tip 42a1 that is bent and extends in the up-down direction.

[0099] 12, the plate thickness of the first fitting 40a is substantially the same as or smaller than the plate thickness of the second fitting 40b. Without being limited thereto, the plate thickness of the first fitting 40a may be larger than the plate thickness of the second fitting 40b so that the strength of the first fitting 40a is greater than the strength of the second fitting 40b even in cases where the first fitting 40a and the second fitting 40b are made of the same material, for example.

[0100] According to the connector 10 according to the embodiment described above, robustness is improved even in a small and low-profile state. For example, robustness is improved during and after fitting of the connector 10 and the connection object 50, even in a small and low-profile state.

[0101] In the connector 10, the first metal fitting 40a has a first end 41a1 disposed at the first intersection R1 of the mating protrusion 22 and a second end 41a2 disposed at the second intersection R2 of the mating protrusion 22. This allows the connector 10 to reliably protect each intersection of the mating protrusion 22 where defects such as crushing and scraping are likely to occur during the mating and removal of the connector 10 and the connection object 50. A part of the first insulator 20 is covered by the first metal fitting 40a at each intersection of the mating protrusion 22, improving the robustness of each intersection of the first insulator 20. This prevents defects such as scraping of the mating protrusion 22 of the first insulator 20 due to contact with the connection object 50 during the mating and removal of the connector 10 and the connection object 50. This also prevents poor contact caused by chips of the scraped first insulator 20 adhering to the first contact 30. As a result, the reliability of the connector 10 as a product is improved.

[0102] The first metal fitting 40a, by having the first extending portion 41a3, can also protect the first intersection line L1 and adjacent areas along the first intersection line L1 on the first surface 221 and the second surface 222. The first metal fitting 40a, by having the second extending portion 41a4, can also protect the second intersection line L2 and adjacent areas along the second intersection line L2 on the first surface 221 and the third surface 223. As a result, the robustness of the fitting protrusion 22 is further improved. As a result, the robustness of the first insulator 20 is further improved. Therefore, the connector 10 exhibits the above-mentioned effects regarding robustness and reliability more significantly.

[0103] The first metal fitting 40a has the third extension portion 41a5, and therefore can protect the third intersection line L3 and the adjacent areas along the third intersection line L3 on the second surface 222 and the fourth surface 224. The first metal fitting 40a has the fourth extension portion 41a6, and therefore can protect the fourth intersection line L4 and the adjacent areas along the fourth intersection line L4 on the third surface 223 and the fourth surface 224. As a result, the robustness of the fitting protrusion 22 is further improved. As a result, the robustness of the first insulator 20 is further improved. Therefore, the connector 10 exhibits the above-mentioned effects on robustness and reliability more significantly. For example, the third extension portion 41a5 and the fourth extension portion 41a6 can suppress scraping and crushing of the corresponding portions of the fitting protrusion 22 even when the connection object 50 tries to rotate in a plane perpendicular to the up-down direction relative to the connector 10 during or after the connector 10 and the connection object 50 are engaged with each other.

[0104] The first metal fitting 40a, by having the fifth extension portion 41a7, can also protect the fifth intersection line L5 and the adjacent regions along the fifth intersection line L5 on the first surface 221 and the fourth surface 224. As a result, the robustness of the fitting protrusion 22 is further improved. As a result, the robustness of the first insulator 20 is further improved. Therefore, the connector 10 exhibits the above-mentioned effects on robustness and reliability more significantly. For example, the fifth extension portion 41a7 can suppress scraping and crushing of the fifth intersection line L5 of the fitting protrusion 22, which is most likely to come into contact with the connection object 50 during the fitting between the connector 10 and the connection object 50, and the adjacent regions along the fifth intersection line L5 on the first surface 221 and the fourth surface 224.

[0105] The first metal fitting 40a has at least one of the first plane S1, the second plane S2, the third plane S3, and the fourth plane S4, and thus can protect at least one of the first surface 221, the second surface 222, the third surface 223, and the fourth surface 224. As a result, the robustness of the fitting protrusion 22 is further improved. As a result, the robustness of the first insulator 20 is further improved. Therefore, the connector 10 exhibits the above-mentioned effects regarding robustness and reliability more significantly.

[0106] The first metal fitting 40a continuously covers the first surface 221, the second surface 222, the third surface 223, and the fourth surface 224, as well as all intersection lines, with surfaces perpendicular to the plate thickness direction, thereby making it possible to protect the first insulator 20 without exposing it at the longitudinal end of the fitting protrusion 22. This effect is achieved by the first base portion 41a formed by drawing. As a result, the robustness of the fitting protrusion 22 is further improved. As a result, the robustness of the first insulator 20 is further improved. Therefore, the connector 10 exhibits the above-mentioned effects regarding robustness and reliability more significantly.

[0107] The first flat surface S1 of the first base portion 41a is flush with the upper surface of the fitting protrusion 22, and the second flat surface S2 and the third flat surface S3 of the first base portion 41a are flush with the side surfaces of the fitting protrusion 22. This allows the first metal fitting 40a and the first insulator 20 to be smoothly connected to each other without any step between them. This further improves the robustness of the fitting protrusion 22. As a result, this further improves the robustness of the first insulator 20. This allows the connector 10 to more significantly achieve the above-mentioned effects regarding robustness and reliability.

[0108] In the connector 10, the first metal fitting 40a attached to the mating protrusion 22 and the second metal fitting 40b attached to the outer peripheral wall 23 are different members. This reduces the influence of contact between the metal fitting and the connection object 50 during mating, compared to the conventional technology in which the metal fittings are integrally formed. For example, even if the metal fitting and the connection object 50 come into contact with each other on one side of the mating protrusion 22 and the outer peripheral wall 23, the influence of the contact on the other side is suppressed. This suppresses damage to the metal fittings, including the first metal fitting 40a and the second metal fitting 40b. By suppressing damage to the metal fittings, damage to the first insulator 20 to which the metal fittings are attached is also suppressed. As a result, the reliability of the connector 10 as a product is improved.

[0109] Even if the connection object 50 is engaged with the connector 10 in a misaligned position, and the connection object 50 comes into contact with the second metal fitting 40b on the outer peripheral wall 23 side during the engagement, causing the second metal fitting 40b and the outer peripheral wall 23 to deform so as to fall outward in the left-right direction, the effect on the fitting protrusion 22 side is suppressed. That is, the first metal fitting 40a and the second metal fitting 40b are made of different materials, so that the deformation of the first metal fitting 40a is suppressed. Even if the connection object 50 comes into contact with the first metal fitting 40a on the fitting protrusion 22 side during the engagement, causing the first metal fitting 40a and the fitting protrusion 22 to deform so as to be recessed inward in the left-right direction, the effect on the outer peripheral wall 23 side is suppressed. That is, the first metal fitting 40a and the second metal fitting 40b are made of different materials, so that the deformation of the second metal fitting 40b is suppressed. In this way, the metal fittings on one side of the fitting protrusion 22 and the outer peripheral wall 23 behave independently and separately. Therefore, the transmission of the behavior to the other side is suppressed. As a result, the entire metal fitting can stably perform the desired function, reducing the risk of breakage.

[0110] As described above, damage to the metal fittings and the first insulator 20 is suppressed, and thus misalignment in the contact arrangement direction, i.e., in the longitudinal direction of the connector 10, between the connector 10 and the connection object 50 during and after mating is suppressed. This allows electrical continuity between the first contacts 30 and the second contacts 70 to be accurately achieved according to the original design. In addition, rattling of the connector module 1 after mating is suppressed. That is, the function of regulating the position of one of the connector 10 and the connection object 50 relative to the other is maintained. As a result, one is less likely to come off the other, improving the reliability of the connector module 1 as a product.

[0111] In the connector 10, the first metal fitting 40a and the second metal fitting 40b are made of different materials, which makes it possible to make the strength of one of the first metal fitting 40a and the second metal fitting 40b higher than the strength of the other. In the connector 10, the first metal fitting 40a and the second metal fitting 40b are attached for different purposes in different locations, such as the mating protrusion 22 and the outer peripheral wall 23, and it is possible to form each metal fitting with an appropriate strength suited to the location and purpose. For example, if the metal fittings are integrally formed as in the conventional technology, when the strength of the metal fittings must be reduced on one side of the mating protrusion 22 and the outer peripheral wall 23, the strength of the metal fittings will inevitably be reduced on the other side as well.

[0112] For example, the main purpose of the first metal fitting 40a attached to the fitting protrusion 22 is to improve the robustness of the fitting protrusion 22. On the other hand, the main purpose of the second metal fitting 40b attached to the outer peripheral wall 23 is to contact the metal fitting 80 in the fitted state to obtain electrical continuity. For this purpose, the second metal fitting 40b is formed with an elastically deformable contact piece 48b.

[0113] Therefore, it is preferable that the second metal fitting 40b is made of a material strong enough to provide springiness, while the first metal fitting 40a is made of a material with even higher strength. In the connector 10, the first metal fitting 40a and the second metal fitting 40b can be formed with appropriate strength suited to their respective purposes. For example, if the metal fittings are integrally formed as in the prior art, the strength of the entire metal fitting is inevitably reduced by forming elastically deformable contact pieces on the outer peripheral wall side, and the robustness of the mating protrusions is also reduced.

[0114] By making the material of the first fitting 40a different from the material of the second fitting 40b, it is possible to easily form each fitting so that one of the first fitting 40a and the second fitting 40b has a higher strength than the other. For example, it is possible to appropriately select the material of each fitting according to the above-mentioned purpose of the first fitting 40a and the second fitting 40b.

[0115] The strength of the material of the first metal fitting 40a is greater than the strength of the material of the second metal fitting 40b, which improves the robustness of the fitting protrusion 22 to which the first metal fitting 40a is attached. This reduces damage to the fitting protrusion 22 of the first insulator 20 to which the first metal fitting 40a is attached. As a result, the reliability of the connector 10 as a product is improved.

[0116] Since the plate thickness of the first fitting 40a is greater than the plate thickness of the second fitting 40b, even if the first fitting 40a and the second fitting 40b are made of the same material, the strength of the first fitting 40a is greater than the strength of the second fitting 40b. This improves the robustness of the fitting protrusion 22 to which the first fitting 40a is attached in the same manner as described above.

[0117] By attaching the pair of first metal fittings 40a to both ends of the fitting protrusion 22 in the longitudinal direction of the connector 10, the robustness of the fitting protrusion 22 is improved at both ends of the fitting protrusion 22. Therefore, damage to the fitting protrusion 22 of the first insulator 20 to which the pair of first metal fittings 40a are attached is further suppressed. As a result, the reliability of the connector 10 as a product is further improved.

[0118] In the connector 10, the first metal fitting 40a has a mounting portion 45a that is mounted on the circuit board CB1, and this improves the robustness of the first metal fitting 40a. That is, even if a load is applied to the first metal fitting 40a, its deformation is suppressed, and the shape and dimensional accuracy of the connector 10 are maintained even during mating. For example, the robustness of the mating protrusion 22 to which the first metal fitting 40a is attached is improved. Therefore, damage such as deformation of the mating protrusion 22 is suppressed, and the above-mentioned effect regarding longitudinal positional deviation and rattling of the connector 10 is obtained.

[0119] Since the mounting portion 45a includes the bottom surface of the second base portion 43a that extends along the longitudinal direction of the connector 10 on the circuit board CB1 side, external force acting on the first metal fitting 40a can be received by the mounting portion 45a. That is, by mounting the mounting portion 45a on the circuit board CB1, the first metal fitting 40a is fixed to the circuit board CB1, and even if an external force acts on the first metal fitting 40a, the impact is absorbed by the mounting portion 45a. Therefore, the robustness of the first metal fitting 40a along the longitudinal direction of the connector 10 is improved. This also improves the robustness of the fitting protrusion 22 along the longitudinal direction of the connector 10.

[0120] The first metal fitting 40a overlaps, along the arrangement direction, one of the multiple first contacts 30 that is located at the end in the arrangement direction, thereby shortening the longitudinal width of the connector 10. This shortens the longitudinal width of the connector module 1, making the connector module 1 more compact. In addition, the connector module 1 is more resistant to external forces.

[0121] The tip 42a1 of the claw portion 42a of the first metal fitting 40a is located between one first contact 30 and another first contact 30 in the arrangement direction. As a result, any tip structure of the claw portion 42a is arranged in a part of the first insulator 20 where the first contact mounting groove 24 is not formed and the thickness is large. Therefore, the holding strength of the tip 42a1 of the claw portion 42a to the first insulator 20 is improved. As a result, the holding strength of the first metal fitting 40a to the first insulator 20 is improved. On the other hand, by arranging any tip structure of the claw portion 42a in a part of the first insulator 20 where the thickness is large, a decrease in the rigidity of the fitting protrusion 22 of the first insulator 20 is suppressed compared to a case where the tip structure of the claw portion 42a is arranged so as to overlap with a part where the first contact mounting groove 24 is formed.

[0122] The claw portion 42a is formed in an L-shape, and the tip 42a1 of the claw portion 42a is embedded inside the fitting protrusion 22, thereby preventing the claw portion 42a from curling up. This improves the holding strength of the claw portion 42a to the first insulator 20. This improves the holding strength of the first metal fitting 40a to the first insulator 20.

[0123] The first base portion 41a and the second base portion 43a are integrally formed to have a crank shape as a whole, so that the entire first metal fitting 40a is integrated with the first insulator 20 along the shape of the end portion of the fitting protrusion 22 and the bottom plate portion 21. This improves the holding strength of the first metal fitting 40a to the first insulator 20.

[0124] In the short direction of the connector 10, the claw portion 42a is narrower than other portions of the first metal fitting 40a, so that the thickness of the first insulator 20 is increased at the portion integrated with the claw portion 42a. For example, even if the claw portion 42a overlaps with one of the first contacts 30 located at the end in the arrangement direction along the arrangement direction and the first contact mounting groove 24 is formed in a corresponding portion, the strength of the first insulator 20 is maintained because the claw portion 42a is formed narrow. As a result, the robustness of the connector 10 is improved.

[0125] The second base 43a of the first metal fitting 40a extends along the longitudinal direction of the connector 10 from the mating protrusion 22 to the short wall 23a to which the second metal fitting 40b is attached, thereby improving the robustness of the first metal fitting 40a along the longitudinal direction of the connector 10. This also improves the robustness of the mating protrusion 22 along the longitudinal direction of the connector 10. In addition, the same effect as above can be obtained between the short wall 23a and the mating protrusion 22, which are spaced apart from each other in the longitudinal direction of the connector 10. In other words, even if the metal fitting and the connection object 50 come into contact with each other on one side of the mating protrusion 22 and the short wall 23a, the effect of the contact on the other side is suppressed.

[0126] The first mounting portions 44b of the second metal fitting 40b are disposed on both sides of the first metal fitting 40a in the short-side direction of the connector 10. The second mounting portions 49b of the second metal fitting 40b are disposed on both sides of the first metal fitting 40a in the short-side direction of the connector 10. As a result, the mounting strength of the second metal fitting 40b to the circuit board CB1 is improved. This improves the robustness of the second metal fitting 40b and the short-side wall 23a in the left-right direction.

[0127] The pair of first mounting parts 44b are disposed at substantially the same left-right position as the mounting parts 45a, so that the three mounting parts are positioned on a straight line along the front-rear direction. This improves the mounting strength of the connector 10 to the circuit board CB1. For example, even if the connection object 50 is misaligned at a predetermined angle with respect to the connector 10 about an axis in the up-down direction when the connector 10 is mated, the mounting of the connector 10 to the circuit board CB1 is maintained. Similarly, even if the circuit board CB1 on which the connector 10 is mounted rotates after mating, the mounting of the connector 10 to the circuit board CB1 is maintained. Therefore, the robustness of the connector 10 mounted on the circuit board CB1 is improved.

[0128] By arranging parts of the second metal fitting 40b on both sides of the second base portion 43a of the first metal fitting 40a in the short direction of the connector 10, the attachment area of ​​the second metal fitting 40b to the first insulator 20 is increased. Therefore, the attachment strength of the second metal fitting 40b to the first insulator 20 is improved.

[0129] By attaching the pair of second metal fittings 40b to the pair of short walls 23a, respectively, the robustness of the short walls 23a is improved at both left and right ends of the outer peripheral wall 23. Therefore, damage to the short walls 23a of the first insulator 20 to which the pair of second metal fittings 40b are attached is further suppressed. As a result, the reliability of the connector 10 as a product is further improved.

[0130] The second metal fitting 40b has an elastically deformable contact piece 48b that comes into contact with the metal fitting 80 in the fitted state, and as a result, the elastic force of the contact piece 48b enables the second metal fitting 40b to stably maintain a connected state with the metal fitting 80. Therefore, electrical continuity between the second metal fitting 40b and the metal fitting 80 is stably maintained in the fitted state.

[0131] By the first metal fitting 40a and the second metal fitting 40b facing each other in the left-right direction while separated from each other, in the mated state in which the connector 10 and the connection object 50 are mated with each other, the metal fitting 80 of the connection object 50 can be positioned between the first metal fitting 40a and the second metal fitting 40b. In this way, by the second metal fitting 40b being positioned so as to sandwich the metal fitting 80 together with the first metal fitting 40a in the mated state, rattling of the connector module 1 after mating is suppressed. That is, the shape and dimensional accuracy of the connector 10 are maintained during mating, and the function of regulating the position of one of the connector 10 and the connection object 50 relative to the other is maintained even after mating. As a result, one is less likely to come off from the other, improving the reliability of the connector module 1 as a product.

[0132] The first metal fitting 40a and the first insulator 20 are integrally molded by insert molding, which further improves the robustness of the first metal fitting 40a and the fitting protrusion 22. The second base portion 43a of the first metal fitting 40a is integrally molded with the first insulator 20 inside the bottom plate portion 21 at the second portion 252 of the first metal fitting holding portion 25, which increases the contact area between the first metal fitting 40a and the first insulator 20. This improves the holding strength of the first metal fitting 40a against the first insulator 20 by insert molding. Therefore, the robustness of the first metal fitting 40a and the fitting protrusion 22 is further improved. The above-mentioned effects are further remarkable when the wide portion 44a of the first metal fitting 40a is embedded inside the bottom plate portion 21 at the second portion 252 of the first metal fitting holding portion 25.

[0133] It is obvious to those skilled in the art that the present disclosure can be realized in other specific forms other than the above-described embodiments without departing from the spirit or essential characteristics thereof. Therefore, the above description is illustrative and not limiting. The scope of the disclosure is defined by the appended claims, not by the above description. Any modifications within the scope of the equivalents of all modifications are intended to be included therein.

[0134] For example, the shape, arrangement, orientation, and number of each of the above-mentioned components are not limited to the above description and the contents illustrated in the drawings. The shape, arrangement, orientation, and number of each of the components may be arbitrarily configured as long as the function can be realized.

[0135] For example, in the connector 10, the second metal fitting 40b may be integrally molded with the first insulator 20 by insert molding rather than by press fitting. For example, in the connector 10, the first metal fitting 40a may be attached to the first insulator 20 by press fitting rather than by insert molding.

[0136] In the above embodiment, the first metal fitting 40a is described as being disposed singly at one end in the left-right direction of the fitting protrusion 22, but this is not limited thereto. The first metal fitting 40a may be configured as a pair of members disposed spaced apart from each other at the first end 41a1 and the second end 41a2, for example. In this manner, the first metal fitting 40a may be configured by a plurality of members.

[0137] In the above embodiment, the first metal fitting 40a has been described as having the first extending portion 41a3 and the second extending portion 41a4, but is not limited thereto. The first metal fitting 40a may have only one of the first extending portion 41a3 and the second extending portion 41a4, or may not have both of these extending portions.

[0138] In the above embodiment, the first metal fitting 40a has been described as having the third extending portion 41a5 and the fourth extending portion 41a6, but is not limited thereto. The first metal fitting 40a may have only one of the third extending portion 41a5 and the fourth extending portion 41a6, or may not have both of these extending portions.

[0139] In the above embodiment, the first fitting 40a has been described as having the fifth extending portion 41a7, but this is not limited thereto. The first fitting 40a does not necessarily have to have the fifth extending portion 41a7.

[0140] In the above embodiment, the first fitting 40a has been described as having the first plane S1, the second plane S2, the third plane S3, and the fourth plane S4, but is not limited thereto. The first fitting 40a may have at least one of the first plane S1, the second plane S2, the third plane S3, and the fourth plane S4, or may not have the first plane S1, the second plane S2, the third plane S3, and the fourth plane S4. The first fitting 40a may be formed so that, instead of at least one of the first plane S1, the second plane S2, the third plane S3, and the fourth plane S4, the corresponding surface is curved.

[0141] In the above embodiment, the first fitting 40a has been described as continuously covering the first surface 221, the second surface 222, the third surface 223, and the fourth surface 224, as well as all of the intersection lines, with surfaces perpendicular to the plate thickness direction at the longitudinal ends of the fitting protrusion 22, but this is not limited to the above. As long as the first fitting 40a has the first end 41a1 and the second end 41a2, it may be formed into any shape by any processing method not including drawing.

[0142] In the above embodiment, the first fitting 40a and the second fitting 40b are described as being separate from each other, but this is not limited thereto. The first fitting 40a and the second fitting 40b may be connected to each other without being separated from each other. In this case, the first fitting 40a and the second fitting 40b may be formed so that their respective strengths are different from each other in the entire integrated fitting. For example, the integrated fitting including the first fitting 40a and the second fitting 40b may be formed from a functionally graded material. More specifically, the material of the first fitting 40a may be a material different from the material of the second fitting 40b so that its strength is higher than that of the material of the second fitting 40b. For example, the integrated fitting including the first fitting 40a and the second fitting 40b may be formed so that the plate thickness changes. More specifically, the plate thickness of the first fitting 40a may be larger than the plate thickness of the second fitting 40b.

[0143] In the above embodiment, the strength of the first metal fitting 40a is greater than the strength of the second metal fitting 40b, but this is not limited to the above. The strength of the second metal fitting 40b may be greater than the strength of the first metal fitting 40a.

[0144] In the above embodiment, it has been described that the plate thickness of the first fitting 40a may be greater than the plate thickness of the second fitting 40b so that the strength of the first fitting 40a is greater than the strength of the second fitting 40b, but this is not limited to the above. For example, the plate thickness of the first fitting 40a may be smaller than the plate thickness of the second fitting 40b, or the strength of the first fitting 40a may be greater than the strength of the second fitting 40b. Conversely, the plate thickness of the first fitting 40a may be greater than the plate thickness of the second fitting 40b, or the strength of the first fitting 40a may be lower than the strength of the second fitting 40b.

[0145] In the above embodiment, the first metal fitting 40a is described as overlapping one of the first contacts 30 along the arrangement direction, but is not limited thereto. If it is possible to reduce the size of the connector 10 in the longitudinal direction, the first metal fitting 40a does not need to overlap one of the first contacts 30 along the arrangement direction.

[0146] In the above embodiment, the tip 42a1 of the claw portion 42a of the first metal fitting 40a is described as being located between one first contact 30 and another first contact 30 in the arrangement direction, but this is not limited to this. As long as the holding strength of the tip 42a1 of the claw portion 42a to the first insulator 20 can be maintained, the tip 42a1 of the claw portion 42a of the first metal fitting 40a may be located in the same left-right position as the attachment position of the first contact 30, for example.

[0147] In the above embodiment, the claw portion 42a is formed in an L-shape, and the tip 42a1 of the claw portion 42a is embedded inside the fitting protrusion 22, but this is not limited to the above. As long as the holding strength of the claw portion 42a with respect to the first insulator 20 can be maintained, the claw portion 42a may be formed in any shape other than the L-shape. Similarly, the tip 42a1 of the claw portion 42a does not have to be embedded inside the fitting protrusion 22.

[0148] In the above embodiment, the claw portion 42a is described as being narrower than the other portions of the first metal fitting 40a in the short-side direction of the connector 10, but is not limited thereto. As long as the strength of the first insulator 20 is maintained, the claw portion 42a may have the same width as the other portions of the first metal fitting 40a.

[0149] In the above embodiment, the second base 43a is described as extending from the fitting protrusion 22 to the short wall 23a to which the second metal fitting 40b is attached, but this is not limited to this. As long as the robustness of the first metal fitting 40a along the longitudinal direction of the connector 10 is improved, the second base 43a may extend from the fitting protrusion 22 toward the short wall 23a by any length.

[0150] In the above embodiment, the mounting portion 45a is described as being located directly below the short wall 23a, but this is not limited thereto. The mounting portion 45a may be located adjacent to the fitting protrusion 22 so as to be close to a position on the first fitting 40a where an external force is likely to act.

[0151] In the above embodiment, the second metal fitting 40b is attached to the short wall 23a, but this is not limited to the above. For example, the second metal fitting 40b may not be attached to the short wall 23a, but may be attached only to the long wall 23b.

[0152] In the above embodiment, the first mounting portion 44b of the second metal fitting 40b is disposed on both sides of the first metal fitting 40a in the short-side direction of the connector 10, and the second mounting portion 49b is disposed on both sides of the first metal fitting 40a in the short-side direction of the connector 10, but this is not limited to the above. One of the first mounting portion 44b and the second mounting portion 49b may be disposed on both sides of the first metal fitting 40a in the short-side direction of the connector 10. Only one first mounting portion 44b may be formed instead of two, or three or more. Similarly, only one second mounting portion 49b may be formed instead of two, or three or more.

[0153] In the above embodiment, the second metal fitting 40b has been described as having an elastically deformable contact piece 48b that comes into contact with the metal fitting 80 of the connection target object 50 in the fitted state, but this is not limited to the above. The second metal fitting 40b may come into contact with the metal fitting 80 without elastically deforming, or may not come into contact with the metal fitting 80 at all.

[0154] In the above embodiment, the first surface 221, the second surface 222, the third surface 223, and the fourth surface 224 of the fitting protrusion 22 of the first insulator 20 are all described as flat surfaces, but are not limited thereto. The first surface 221, the second surface 222, the third surface 223, and the fourth surface 224 may be curved surfaces. The first intersection line L1, the second intersection line L2, the third intersection line L3, the fourth intersection line L4, and the fifth intersection line L5 may all be curved lines rather than straight lines. The first intersection portion R1 and the second intersection portion R2 are not limited to a configuration formed as a corner including one intersection point based on the intersection of three planes, and may be formed as an R shape.

[0155] The connector module 1, the connector 10, or the connection object 50 as described above is mounted on an electronic device including a circuit board CB1 and a circuit board CB2. The electronic device includes, for example, any communication terminal device such as a smartphone, and any information processing device such as a personal computer, a copier, a printer, a facsimile, and a multifunction device. The electronic device includes, for example, any in-vehicle device such as a camera, a radar, a drive recorder, and an engine control unit. The electronic device includes, for example, any other in-vehicle device used in an in-vehicle system such as a car navigation system, an advanced driving assistance system, or a security system. In addition, the electronic device includes any industrial device.

[0156] In such an electronic device, even when the connector 10 is made small and low-profile, the robustness of the connector 10 is improved during the mating process between the connector 10 and the connection object 50. This improves the reliability of the electronic device as a product. [Explanation of symbols]
