Description

  The present invention relates to a shielded connector connected to an end of a shielded cable, and a shielded cable with a connector including the shielded connector. In particular, the present invention relates to a shield connector having excellent shielding properties.

  Conventionally, shielded cables have been used for communication between electrical components (navigation devices, ETC (Electronic Toll Collection) devices, monitors, etc.) mounted on vehicles such as automobiles and external devices (cameras, etc.) and between electrical components. ing. A shielded cable for communication generally includes an electric wire including a communication line, a shield conductor that collectively covers the periphery of the electric wire, and a sheath that covers the outer periphery of the shield conductor. The electric wire has a conductor and an insulating coating on the outer periphery thereof.

  Usually, a shield connector is attached to the end of the shield cable.

  At the end of the shield cable to which the shield connector is connected, the end of the electric wire is exposed from the shield conductor, but the end of the inner housing and the shield cable is accommodated in the shield shell. Therefore, the periphery of the inner housing and the exposed end of the electric wire is covered by the shield shell. By shielding the electromagnetic wave noise with the shield shell at the end of the shielded cable, the shielding property is secured, and the intrusion of the electromagnetic wave noise from the outside and the leakage of the electromagnetic wave noise generated from the electric wire are suppressed. From the viewpoint of enhancing the shielding performance of the shield connector, it is desirable to cover the entire circumference of the inner housing and the exposed end of the electric wire with the shield shell so that a gap or opening is not generated in the shield shell as much as possible.

  In the conventional shield connector described in Patent Document 1, a shield shell is configured by attaching a cover (cover plate portion) so as to cover from above the base. Since the cover (cover plate portion) has a flat plate shape, a cut is formed between the cover plate portion and the side plate portion of the base in the shield shell, and a gap may be generated in the circumferential direction of the shield shell. Therefore, there is a high possibility that the periphery of the inner housing and the exposed end portion of the electric wire cannot be covered with the shield shell over the entire circumference, and there is a possibility that sufficient shielding performance cannot be ensured. In particular, when the shielded cable has a communication line for high-speed communication, the communication line for high-speed communication is easily affected by electromagnetic wave noise, and if the shielding property of the shield connector is low, the communication quality is deteriorated.

  Moreover, in the shield connector described in Patent Document 1, in order to fix the inner housing to the base of the shield shell, the side plate portion of the base is cut out to form the engagement protrusion. For this reason, in the shield shell, the notched portion becomes an opening, so that a gap is generated in the circumferential direction of the shield shell, resulting in a decrease in shielding performance.

  This invention is made | formed in view of the said situation, and one of the objectives of this invention is to provide the shielded cable with a connector provided with the shield connector excellent in shielding property, and this shield connector.

  The shield connector which concerns on 1 aspect of this invention is connected to the edge part of the shield cable which has an electric wire containing at least 1 communication line, and the shield conductor which coat | covers the circumference | surroundings of the said electric wire collectively. The shield connector includes an inner housing that holds a terminal connected to a conductor end of the electric wire, and a cable insertion portion that accommodates the end of the inner housing and the shield cable and into which the end of the shield cable is inserted. A shield shell. The inner housing has a convex portion protruding from a side surface. The shield shell has a base on which the inner housing is disposed, and a cover fitted to the base. The base covers a lower surface of the inner housing and extends from both sides of the bottom plate portion so as to cover both side surfaces of the bottom plate portion extending toward the cable insertion portion, and the cable insertion portion. A pair of base side plate portions formed in series toward the base, and an engagement hole formed in the base side plate portion and engaged with the convex portion of the inner housing. The cover covers the upper surface of the inner housing, the upper plate portion extending toward the cable insertion portion, and the upper plate portion so as to cover the engagement hole overlapping the outside of the base side plate portion. It has a pair of cover side plate portions that are erected from both sides and are formed in series toward the cable insertion portion.

<Effect>
The shield connector 10 and the shielded cable 1 with the connector according to the first embodiment have the following effects.

  (1) The base 41 and the cover 51 constituting the shield shell 40 have a base side plate portion 43 and a cover side plate portion 53, respectively. The cover side plate portion 53 overlaps with the base side plate portion 43, and the base side plate portion 43 is engaged. The holes 45 and 46 and the vertical hole 47 are covered. Further, the base 41 (the bottom plate portion 42 and the base side plate portion 43) and the cover 51 (the upper plate portion 52 and the cover side plate portion 53) are respectively formed in series from the housing accommodating portion 61 to the cable insertion portion 63. Therefore, the shield connector 10 is unlikely to have a gap in the circumferential direction of the shield shell 40 and can cover the periphery of the inner housing 20 and the exposed end of the electric wire 110 with the shield shell 40 over the entire circumference. Therefore, the shield connector 10 can effectively suppress intrusion and leakage of electromagnetic noise, and has excellent shielding properties. Moreover, since the shielded cable 1 with a connector includes the shield connector 10, the shield property of the shield connector 10 is high, and the communication quality can be improved. In particular, when applied to a shielded cable having communication lines 121 and 122 for high-speed communication, improvement in communication quality can be expected.

  (2) Since the inner housing 20 can be positioned and fixed to the base 41 by the engagement between the convex portions 25 and 35 of the inner housing 20 and the engagement holes 45 and 46 of the base side plate portion 43, the assembly of the shield connector 10 Excellent. Further, the vertical movement of the inner housing 20 with respect to the base 41 and the inclination of the inner housing 20 can be suppressed by the engagement between the convex portions 25 and 35 and the engagement holes 45 and 46. Furthermore, by inserting the vertical ribs 27 of the inner housing 20 into the vertical holes 47 of the base side plate portion 43, the movement of the inner housing 20 in the front-rear direction relative to the base 41 and the inclination of the inner housing 20 can be effectively controlled. By restricting the movement of the inner housing 20 relative to the shield shell 40, the impedance between the inner housing 20 and the shield shell 40 hardly changes. Therefore, it is possible to effectively suppress a deterioration in communication quality due to impedance mismatch in the shield connector 10.

  (3) Since the cover 51 can be positioned and fixed to the base 41 by fitting the projection 44 of the base side plate portion 43 and the fitting hole 54 of the cover side plate portion 53, the assembly of the shield connector 10 is excellent. Since the protrusion 44 is formed by striking (striking), a portion where the protrusion 44 is formed is not substantially opened in a direction perpendicular to the outer surface of the base side plate portion 43, and a gap is formed in the circumferential direction of the shield shell 40. Can be prevented. Further, by providing the projection 44 on the base side plate portion 43 and the fitting hole 54 on the cover side plate portion 53, when assembling the shield shell 40 by fitting the base 41 and the cover 51, the projection 44 and the fitting hole 54 are provided. Can be visually confirmed from the outside of the shield shell 40. Also in this point, the assembly of the shield connector 10 is excellent.

  (4) The protrusions 58 of the cover side plate portion 53 are inserted into the vertical grooves 28 of the inner housing 20, whereby the cover 51 can be positioned with respect to the inner housing 20. Thereby, positioning of the inner housing 20 and the shield shell 40 (base 41 and cover 51) can be performed with higher accuracy.

  (5) Since the crimping pieces 71 and 72 of the barrel part 70 are crimped to the end of the shield conductor 130, the shield shell 40 and the shield conductor 130 can be electrically connected. Further, the shield shell 40 (shield connector 10) can be firmly connected to the end of the shield cable 100, and the movement of the shield shell 40 in the front-rear direction can be restricted. Furthermore, by having the protruding piece 75 so as to face the barrel portion 70, the concentration of the tightening force can be dispersed when the crimping pieces 71 and 72 are crimped, and excessive deformation of the end portion of the shield conductor 130 due to the crimping is prevented. While being able to do so, the shield connector 10 can be connected more firmly. Accordingly, the pullout strength of the shielded cable 100 can be sufficiently ensured.

  The shielded connector and the shielded cable with the connector of the present invention can be suitably used as a shielded cable for high-speed communication.
