Definitions

  • This invention concerns an electrical connector and a cable with an electrical connector, used for electrically connecting a cable such as an FFC (Flexible Flat Cable) with a contact of a counterpart connector.
  • a cable such as an FFC (Flexible Flat Cable)
  • FFC Flexible Flat Cable
  • An electrical connector includes a contact for electrical connection with a contact of a counterpart connector, and a housing which houses and holds the contact.
  • a cable passage is formed for passing a cable attached to the contact housed in the housing (for example, a flat cable such as an FFC) .
  • a cable attached to the contact housed in the housing for example, a flat cable such as an FFC
  • the housing is twisted with respect to the cable or vibration is transmitted from the cable to the contact, there is a possibility that an external force is applied to the contact and cable coupling part. Therefore, for example, it is considered that the cable is fixed by attaching a fixing member to the housing (main body) and fixing the cable inserted through the cable passage by pressing the cable against the housing to restrain an external force from being applied to the contact and cable coupling part.
  • a contact housed in the housing canbe fixed inside the housingby a retainer (for example, refer to Japanese Unexamined Patent Publication No. H11-354185) .
  • the present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide an electrical connector and a cable with an electrical connector, which are assembled readily.
  • the electrical connector of the invention includes a contact for electrical connectionwith a contact of a counterpart connector, a main body having a contact housing part for housing this contact, a coupling member which can be coupled to the main body and can latch a cable that is connected to the contact housed in a contact housing part in conjunction with this main body by being coupled to the main body, and a retainer which is attached in a displaceable manner to the main body and displaces from its initial position to a latching position at which the retainer can latch the contact housed in the contact housing part by receiving an external force from this coupling member when the coupling member is coupled to the main body.
  • a contact insertion passage for inserting the contact inside the contact housing part is formed, and the retainer allows insertion of the contact via the contact insertion passage when the retainer is at the initial position, and when the retainer is at the latching position, it extends to the contact insertion passage to restrict the falling off of the contact housed in the contact housing part.
  • the contact can be housed readily inside the contact housingpart via the contact insertionpassage when the retainer is at its initial position. Thereafter, only by coupling the coupling member to the main body, the cable and the contact can be latched, so that the assembling becomes easier.
  • the coupling member and the main body form and define the cable passage for piercing the cable connected to the contact housed in the contact housing part in a state with practically no bends.
  • first and second clamping parts for clamping the cable are provided, respectively.
  • the cable is clamped in the vicinity of openings at both ends of the cable passage across the coupling part between the contact and the cable, so that it canbe prevented that the electrical connector is twisted with respect to the cable and vibration is transmitted from the cable to the contact. Therefore, application of an external force to the part at which the contact and the cable are coupled to each other can be effectively restrained.
  • the respective first and second clamping parts may include convex portions formed on the coupling member or the main body for pressing the cable.
  • first and second clamping parts may include concave portions opposing the convex portions formed on the coupling member or the main body.
  • the contact may preferably comprise a piercing part equipped with protrusions to be pierced through a conductor of a cable, a linking part linked on one end to the piercing part and extending toward the opposite side of the direction in which the protrusions protrude, and a connection part for electrical connection with a contact of a counterpart connector and linked to the other end of the linking part, and it is preferable that the coupling member and the main body form in a partitioning manner, when they are coupled, the cable passage at a position opposing the protrusions of the contact housed in the contact housing part.
  • a piercing contact comprises a piercing part equipped with protrusions, a linking part which is linked on its one end to the piercing part and extends in the direction substantially orthogonal to the direction in which the protrusions protrude, and a connection part for electrical connection with a contact of a counterpart connector and linked to the other end of the linking part, and the piercing contact has the shape of a substantially straight line as a whole.
  • piercing contacts are attached to intermediate parts of a cable (for example, a flat cable) to branch the intermediate parts of the cable and electrically connect it to other cables, wiringboards, etc., and thereby connect various electrical parts in a chain-like manner (in the manner of a so-called daisy chain connection), when performing piercing on a flat cable by the piercing protrusions of the piercing part upon positioning the cable so as to oppose the piercing part protrusions, the flat cable interferes with the connection part.
  • a cable for example, a flat cable
  • the piercing part and the connection part are linked via a linking part extending toward the opposite side of the direction in which the protrusions protrude, so that, when making a daisy chain connection by attaching the contacts to intermediate parts of a cable to be pierced through the cable passage, the cable can be prevented from interfering with the connection part. Since the cable can be pierced through the cable passage in a state with practically no bends (almost straight), harmful effects in that an excessive stress is applied to the conductor at a bend and the conductor breaks can be prevented.
  • the assembling becomes easier in the electrical connector with which a daisy chain connection can be made without folding back a cable.
  • the linking part may have a substantially L-like form, which extends in a direction substantially orthogonal to the direction in which the protrusions protrude and then extends toward the opposite side of the direction in which the protrusions protrude.
  • connection part may be one with which a contact of a counterpart connector can be attached along the direction in which the protrusions protrude.
  • the protrusions of the piercing part may be pierced into a conductor of a cable, having connectors connected at both ends thereof, at a predetermined position between the connectors.
  • the cable with an electrical connector of the present invention comprises an electrical connector having the above-mentioned characteristics, and a cable that is connected to a contact housed in the contact housing part and latched with respect to the electrical connector by coupling the coupling member to the main body.

Thereafter, only by closing the cover 22 upon connecting the flat cable 40 to the piercing contact 1, the flat cable 40 and the piercing contact 1 can be latched, so that the assembling becomes easier.
  • the housing is not restricted to an arrangement comprising main body 21 and cover 22 and wherein cable passage 30 is formed in a demarcated manner between main body 21 and cover 22, and an arrangement, wherein the main body and the cover are formed integrally, that is, an arrangement, wherein a cable passage for passing flat cable 40 straightly (in a state with practically no bends), is opened in the housing, may be used instead.
  • the flat cable 40 piercing through the cable passage may be latched, and the piercing contact 1 may be latched by displacing the retainer attached to the housing from the initial position to the latching position.
  • the cable passage is not restricted to one piercing through the housing 20, and may instead extend to the intermediate part inside the housing from one end surface of the housing.
  • the piercing contact 1 housed inside the housing is not restricted to that connected to the intermediate part of the flat cable 40, and may instead be connected to the end part of the flat cable 40.
  • Cover 22 is not restricted to one that is linked to main body 21 via linking part 23 and may instead be separated from main body 21.
  • the cover 22 is not restricted to one coupled to the main body 21 by being engaged with the retainer 35, and may instead be engaged with the main body 21.
  • the retainer 35 may be displaced from the initial position to the latching position by pressing the retainer 35 in the process of engaging the cover 22 with the main body 21.
  • the retainer 35 is not restricted to one that latches the piercing contact 1 by contact with the piercing contact 1 housed inside the housing 20, andmay latch the piercing contact 1 by being inserted through the piercing contact 1.
  • the piercing contact 1 is not restricted to that of a substantially L-like form, in which linking part 4 extends forward (in the direction substantially orthogonal to the direction in which piercing protrusions 2 protrude) from the front end of piercing part 3 and thereafter extends downward (toward the opposite side of the direction in which piercing protrusions 2 protrude), and may instead have a shape, wherein linking part 4 extends downward (toward the opposite side of the direction in which piercing protrusions 2 protrude) from an arbitrary position of piercing part 3, or a shape, wherein linking part 4 extends in a direction that is inclined by a predetermined angle (for example, less than 90°) with respect to the direction opposite to the direction in which the piercing protrusions 2 protrude.
  • the piercing contact may have the shape of a substantially straight line as a whole wherein the linking part 4 extends in the direction substantially orthogonal to the direction in which the piercing pro
