Although the effects of the first connector 10 will be mainly described below, the same description applies to the connector module 1 having the first connector 10 as well.

According to the first connector 10 according to the embodiment as described above, it is possible to improve transmission characteristics in signal transmission. Since the first metal member 30 has the extending portion 32 extending from the first base portion 31 along the extending direction of the contact line 42 , the extending portion 32 can be opposed to the contact line 42 . The extending portion 32 faces the exposed portion R of the contact wire 42 so that the extending portion 32 approaches the corresponding portion of the contact wire 42 . This reduces the characteristic impedance of the contact wire 42 in the vicinity of the extension 32 . More specifically, by bringing the electrically conductive extending portion 32 close to the contact line 42 with a space therebetween, an effect similar to that of a capacitor can be obtained therebetween. Assuming that the capacitance is C, the characteristic impedance Z at this time depends on the capacitance C. For example, the characteristic impedance Z is inversely proportional to the square root of the capacitance C, or inversely proportional to the capacitance C. Therefore, by narrowing the space between the capacitors and increasing the capacitance C, the characteristic impedance is reduced. By adjusting the value of the characteristic impedance to approach the ideal value in this manner, the transmission characteristics in signal transmission are improved.

By bringing the first metal member 30 into contact with the second ground portion 43 and facing the contact wire 42 at the facing portion 32 a 1 , the function of the second ground portion 43 of the connection object 40 can be extended to the contact wire 42 . It becomes possible. For example, the contact line 42, the first metal member 30, and the second ground portion 43 function as one shield.

Since first insulator 20 has notch 27 , it is not necessary to form first insulator 20 in the region of notch 27 . Therefore, it is possible to make the vertical width of the first insulator 20 as thin as possible. Thereby, the height of the first insulator 20 can be reduced. As a result, the height of the first connector 10 having the first insulator 20 can be reduced. The height of the second connector 50 can also be reduced in accordance with the reduction in height of the first connector 10 . As a result, the height of the connector module 1 having the first connector 10 and the second connector 50 can be reduced.

By having the first base portion 31 face the second ground portion 43 of the connection object 40 along the extending direction of the contact line 42 , the same effect as the above-described effect regarding the improvement of the transmission characteristics in signal transmission can be obtained.

Since the first metal member 30 has the second extending portion 32b that extends while bending from the first extending portion 32a along the tip surface of the connection object 40 in the extending direction of the contact line 42, the connection object The tip of the object 40 can be protected from the outside by the first extending portion 32 a and the second extending portion 32 b of the first metal member 30 . For example, the first extending portion 32a and the second extending portion 32b cover the tip of the object to be connected 40 from below and behind, respectively, so that the arms of the assembling apparatus, other electronic components, and the circuit board CB are exposed from these directions. etc. can be suppressed from directly contacting the tip of the connection object 40 . Therefore, it is possible to suppress bending of the connection object 40 in the vertical direction due to contact from the outside at the tip of the connection object 40 . As a result, robustness is improved when the first connector 10 holds the connection object 40 .

In addition, since the first metal member 30 has the second extending portion 32b, the curling of the first metal member 30 that occurs when only the first extending portion 32a is provided without the second extending portion 32b is eliminated. Suppressible. For example, in FIG. 10, when the extending portion 32 is formed only up to the first extending portion 32a, the arm of the assembling apparatus and other electronic components are placed between the contact line 42 of the connecting object 40 and the facing portion 32a1. , and the circuit board CB come into contact with each other, and the first metal member 30 tends to curl downward at the first extending portion 32a. Since the first metal member 30 has the second extending portion 32b, such curling of the first metal member 30 is suppressed. Therefore, the robustness of the first connector 10 itself holding the connection object 40 is also improved.

The first metal member 30 has the third extending portion 32c that extends while bending from the second extending portion 32b along the second surface S2 of the connection object 40, so that the tip of the connection object 40 can be moved to the third position. The first extension 32a, the second extension 32b, and the third extension 32c of the first metal member 30 can protect from the outside. For example, the first extending portion 32a, the second extending portion 32b, and the third extending portion 32c cover the tip of the object to be connected 40 from below, rear, and above, respectively, so that the assembling apparatus can be mounted from these directions. It is possible to prevent the arm, other electronic components, the circuit board CB, and the like from directly contacting the tip of the connection object 40 . Therefore, it is possible to further suppress bending of the object to be connected 40 in the vertical direction and curling of the first metal member 30 downward due to contact from the outside at the tip of the object to be connected 40 . As a result, the robustness when the first connector 10 holds the connection object 40 is further improved.

By covering the tip of the connection object 40 with the third extending portion 32c from above, it is possible to directly suppress upward bending of the connection object 40 . Therefore, robustness is further improved when the first connector 10 holds the connection object 40 .

Since the first extending portion 32a includes at least one exposed portion R of the contact wire 42 and the opposing portion 32a1 facing along the extending direction of the contact wire 42, the above-described effect of improving the transmission characteristics in signal transmission It has the same effect as By having the facing portion 32a1 face the exposed portions R of the plurality of contact lines 42, such an effect can be achieved more remarkably.

A pair of opposing portions 32 a 1 are positioned so as to sandwich the exposed portion R of at least one contact wire 42 in the arrangement direction of the plurality of contact wires 42 , so that the extending portion 32 including the opposing portion 32 a 1 is formed at the tip of the connection object 40 . This increases the area that can be protected from the outside. Therefore, it is possible to further suppress bending of the connection object 40 in the vertical direction and curling of the first metal member 30 downward due to external contact at the tip of the connection object 40 . As a result, the robustness when the first connector 10 holds the connection object 40 is further improved.

The first extension portion 32 a faces the second ground portion 43 of the connection object 40 covering the plurality of contact wires 42 along the extending direction of the contact wires 42 , thereby forming a corresponding portion of the second ground portion 43 . Proximity to This reduces the characteristic impedance of the second ground portion 43 in the vicinity of the first extension portion 32a. Therefore, transmission characteristics in signal transmission are further improved.

The facing portion 32 a 1 extends to the tip of the connection object 40 along the exposed portion R positioned to the tip of the connection object 40 . The robustness when held by is further improved.

Since the first metal member 30 has the connecting portion 33 that connects the plurality of third extension portions 32c along the arrangement direction of the plurality of contact lines 42, the first metal member 30 is adjacent to each other along the arrangement direction of the plurality of contact lines 42. The extension part 32 can be strongly connected. Therefore, compared to the case where the third extending portion 32c included in the extending portion 32 is not connected by the connecting portion 33 and is formed as a free end, the one extending portion 32, the connecting portion 33, And the strength can be improved integrally with the other extending portions 32 as a whole. As a result, it is possible to further suppress bending of the connection object 40 in the vertical direction and curling of the first metal member 30 downward due to contact from the outside at the tip of the connection object 40 . As a result, the robustness when the first connector 10 holds the connection object 40 is further improved.

The one third extending portion 32c, the connecting portion 33, and the other third extending portion 32c integrally cover the tip portion of the connection object 40 from above, thereby bending the connection object 40 upward. can be directly suppressed. Therefore, robustness is further improved when the first connector 10 holds the connection object 40 .

One third extending portion 32c, the connecting portion 33, and the other third extending portion 32c integrally cover the tip portion of the connection object 40 from above, thereby preventing the outflow and inflow of noise with respect to electrical signals. Suppressed. For example, electromagnetic noise generated from the electrical signal transmitted by the contact wire 42 is suppressed from flowing out of the first connector 10 . For example, electromagnetic noise generated from another electronic component arranged on the circuit board CB is suppressed from flowing into the first connector 10 .

The contact of the first contact 70a of the second connector 50 with the first metal member 30 increases the ground contact. That is, it becomes possible to electrically connect the first contact 70 a of the second connector 50 to the second ground portion 43 via the first metal member 30 . Therefore, the first contact 70a, the first metal member 30, and the second ground portion 43 function stably as one ground. As a result, transmission characteristics in signal transmission are further improved.

The second base portion 81 is positioned on the second surface S2 side with respect to the connection object 40, and the second metal member 80 is press-fitted into the second insulator 60 from above so as to cover the entire second insulator 60. , the outflow and inflow of noise to the electrical signal are suppressed. For example, electromagnetic noise generated from the electrical signal transmitted by the second contact 70b is suppressed from flowing out of the second connector 50 . For example, electromagnetic noise generated from other electronic components arranged on the circuit board CB is suppressed from flowing into the second connector 50 .

That is, the contact portion 88 contacts the first ground portion 44, which is also exposed upward, from above between the pair of extension portions 32 exposed upward in the notch portion 27 of the first insulator 20. good too.

The contact portion 88 and the second base portion 81 are mutually aligned in the plate thickness direction of the connecting object 40 orthogonal to the extending direction of the contact line 42 in plan view as shown in FIG. 18 along the extending direction of the contact line 42 . May overlap.

The contact portion 88 of the second metal member 80 extends from the second base portion 81 and comes into contact with the connection object 40, thereby increasing the contact points as the ground. The second metal member 80 is electrically connected to the first ground portion 44 of the connection object 40 via the contact portion 88 . Therefore, the first ground portion 44 and the second metal member 80 stably function as one ground. As a result, transmission characteristics in signal transmission are further improved.

Since the contact portion 88 is elastically deformable, the contact reliability is improved. For example, even if the connection target 40 vibrates, the contact with the connection target 40 is more reliably maintained by the elastic deformation of the contact portion 88 . In addition, when the connection object 40 is inserted into the second connector 50, the vertical thickness tolerance of the connection object 40 can be absorbed. Therefore, workability when inserting the connection object 40 held by the first connector 10 into the second connector 50 is improved. In addition, the second connector 50 can hold the connection object 40 more stably than when the contact portions 88 are not elastically deformed. Also, the second connector 50 can improve the reliability of contact with the connection object 40 . As described above, the ease of assembly between the second connector 50 and the object to be connected 40 is improved. As a result, productivity is improved when electronic equipment is produced by electrically connecting the connection object 40 and the circuit board CB via the connector module 1 .

The first connector 10 or connector module 1 as described above is mounted on an electronic device. Electronic devices include, for example, personal computers, game machines, copiers, printers, facsimiles, and any information devices such as multifunction devices. Electronic equipment includes any audiovisual equipment such as LCD televisions, recorders, cameras, and headphones. Without being limited to these, the electronic device may include any vehicle-mounted device such as a camera, radar, drive recorder, and engine control unit. The electronic equipment may include any in-vehicle equipment used in in-vehicle systems such as, for example, car navigation systems, advanced driver assistance systems, and security systems. In addition, electronic equipment may include any industrial equipment.

In such an electronic device, the height of the first connector 10 or the connector module 1 can be reduced, which facilitates miniaturization and thickness reduction of the electronic device. Since the first connector 10 or the connector module 1 described above can improve the transmission characteristics in signal transmission, the reliability of the electronic device as a product is improved.
