A front end edge part of the insulating housing 11 described above is provided with a fit-in convex part 11a to be inserted in the inside of the receptacle connector on a fit-in counterpart side so as to extend in a thin-plate shape along the connector longitudinal direction. When this fit-in convex part 11a of the plug connector 10 is inserted in the inside of the receptacle connector on a fit-in counterpart side, a conductive shell 12 on a plug connector 10 side makes contact with a conductive shell on a receptacle connector (not shown) side. With this contact between the conductive shells, a ground circuit for grounding is formed.
The fit-in convex part 11a provided at the front end edge part of the insulating housing 11 is provided so as to extend in a thin film shape along the connector longitudinal direction. On an upper surface of the fit-in convex part 11a, fit-in contact parts 13e (refer to FIG. 12) formed at a front end side portion (an upper end side portion in FIG. 5) of the conductive contacts 13 described above are arranged so as to form a multipolar electrode shape. The front end side portion of the conductive contacts 13 has its lower side portion excluding its upper surface buried in the insulating housing 11 by insert molding. Also, when the plug connector 10 fits in a receptacle connector (not shown), the upper surface of the conductive contacts 13 described above elastically makes contact with conductive contacts on a receptacle connector side, thereby forming a signal transmission circuit.
Next, a joint relation between the fine-line cables (cable-shaped signal transmission medium) SC and the rear end side portion of the conductive contacts 13 is described, which is a main part of the present invention. As described above, each conductive contact 13 is buried so as to be exposed to the upper surface of the insulating housing 11, and extends in an elongated shape in the fore-and-aft direction (the vertical direction in FIG. 5) from the rear end side portion where the terminal part of the center conductor SC1 of each fine-line cable SC is coupled to the front end side portion toward a receptacle connector as a fit-in counterpart. The surface exposed from the insulating housing 11 at the rear end side portion of the conductive contact 13 forms a cable mounting surface 13a where the fine-line cable SC is mounted from above.
Here, each of the conductive contacts 13 described above has a structure in which a part of the cable mounting surface 13a forming the exposed surface is covered and supported from above by a contact engaging part 11b integrally provided to the insulating housing 11. The contact engaging part 11b as a contact supporting part is disposed between ones of a plurality of conductive contacts 13, and is formed in a block shape rising so as to protrude upwardly from a position corresponding to the rear end side portion (a lower end portion in FIG. 5) of each conductive contact 13. As a specific shape of each contact engaging part 11, a shape is adopted in which an approximately trapezoidal sectional shape continues in a fore-and-aft direction (a vertical direction in FIG. 7).
The contact engaging parts 11b each have an arrangement relation in which a part of a bottom surface of the contact engaging parts 11b, more specifically, a both-side edge portion of the bottom surface in the connector longitudinal direction, covers, from above, a both-end edge portion of the rear end side portion (the lower end portion in FIG. 5) of each conductive contact 13 described above. With this arrangement structure of the contact engaging part 11b, the rear end side portion (the lower end portion in FIG. 5) of each conductive contact 13 can be stably supported without being peeled off from the insulating housing 11.
Also, in a portion between the adjacent contact engaging parts 11b, the center conductor SC1 of the fine-line cable SC as the cable-shaped signal transmission medium described above is inserted as being positionally regulated. That is, each contact engaging part 11b has a side surface part facing another adjacent contact engaging part 11b, and each side surface is formed as an inclined surface rising from the cable mounting surface 13a of the conductive contact 13 described above at a predetermined angle. Also, the inclined surface forming the side surface part of the contact engaging part 11b serves as a guide inclined surface 11c that positions the center conductor SC1 of the fine-line cable (the cable-shaped signal transmission medium) SC.
As such, the guide inclined surfaces 11c each provided on the side surface part of the contact engaging part 11b have an arrangement relation in which the guide inclined surfaces 11c face each other near an outer perimeter surface of the center conductor SC1 in the fine-line cable (the cable-shaped signal transmission medium) SC described above and the guide inclined surfaces 11c in a pair are provided on both sides of the center conductor SC1 of the fine-line cable SC in a diameter direction. Each of these guide inclined surfaces 11c is formed as an inclined surface with an upper open shape continuously spaced apart from another adjacent guide inclined surface 11c in a direction of rising upwardly from the cable mounting surface 13a.
As described above, a distance between the adjacent paired guide inclined surfaces 11c is continuously widened in a rising direction. In particular, as depicted in FIG. 11, the distance between the adjacent paired guide inclined surfaces 11c has a minimum width (W1) at a position along the surface of the cable mounting surface 13a. Also, the minimum width (W1) between the contact engaging parts 11b along the surface of the cable mounting surface 13a is set shorter than an outer diameter dimension (d) of the center conductor SC1 in the fine-line cable (the cable-shaped signal transmission medium) SC (W1<d).
Also, the distance between the paired guide inclined surfaces 11c described above has a maximum width (W2) at a position of a maximum height (h) rising from the cable mounting surface 13a. The maximum distance (W2) between the guide inclined surfaces 11c is set longer than the outer diameter dimension (d) of the center conductor SC1 of the fine-line cable (the cable-shaped signal transmission medium) SC (W2>d).
According to the present embodiment having the structure described above, the center conductor SC1 of the fine-line cable (the cable-shaped signal transmission medium) SC is easily received through a portion with the maximum width (W2) between the paired contact engaging parts 11b, and the center conductor SC1 is then inserted and mounted onto the cable mounting surface 13a as being smoothly guided along the surfaces of both of the guide inclined surfaces 11c. Thus, the operation of mounting the fine-line cables SC can be stably performed by using the contact engaging parts 11b. Therefore, operations at the time of mounting the fine-line cables SC, such as positioning, can be easily and accurately performed, bringing efficiency to the mounting operation.
Furthermore, as described above, the minimum width (W1) between adjacent paired contact engaging parts 11b along the surface of the cable mounting surface 13a is set shorter than the outer diameter dimension (d) of the center conductor SC1 of the fine-line cable (the cable-shaped signal transmission medium) SC (W1<d). Therefore, the fine-line cable SC can be more accurately positioned. Even when the conductor contacts 13 are arranged with narrow pitches, similar operation and effect can be achieved, thereby improving productivity.
Note that when the distance between adjacent paired guide inclined surfaces 11c is minimum on the cable mounting surface 13a and is set shorter than the center conductor SC1 of the fine-line cable (the cable-shaped signal transmission medium) SC (W1<d), at least a distance (W3) between the guide inclined surfaces 11c at the height position corresponding to a diameter (r) of the center conductor SC1 of the fine-line cable SC can be set larger than the outer diameter dimension (d) of the center conductor SC1 (W3>d).
Still further, even when an external force due to so-called flapping or the like is added from the fine-line cable SC to the conductive contact 13 via the fine-line cable (the cable-shaped signal transmission medium) SC, the rear end side portion of the conductive contact 13 to which the fine-line cable SC is coupled is directly held by the contact engaging part 11b provided to the insulating housing 11. Therefore, the conductive contact 13 can be prevented well from being peeled off.
Furthermore, as depicted particularly in FIG. 9 and FIG. 11, the guide inclined surface 11c of the contact engaging part 11b according to the present embodiment is configured to have two-step inclined surfaces in the rising direction. More specifically, the guide inclined surface 11c has a first inclined surface 11c1 rising at a first tilt angle (θ1) with respect to the cable mounting surface 13a described above and a second inclined surface 11c2 extending at a second tilt angle (θ2) with respect to the cable mounting surface 13a from a rising end (an upper end) of the first inclined surface 11c1. Also, the second tilt angle (θ2) is set to be smaller than the first tilt angle (θ1) (θ2<θ1).
With this structure, since the first inclined surface 11c1 first rises in a more vertical state with respect to the cable mounting surface 13a, the first inclined surface 11c1 has an arrangement relation more closer to the center conductor SC1 of the fine-line cable (the cable-shaped signal transmission medium) SC, thereby well positioning the fine-line cable SC. Also, since the second inclined surface 11c2 extends in a more horizontal state, the center conductor SC1 of the fine-line able SC can be received in a wider range at an initial stage of mounting, thereby improving guidability at the time of mounting the fine-line cable SC.
Still further, as depicted particularly in FIG. 11, in the guide inclined surface 11c provided to the contact engaging part 11b in the present embodiment, the maximum height (h) from the cable mounting surface 13a where the center conductor SC1 of the fine-line cable (the cable-shaped signal transmission medium) SC is mounted is set longer than the diameter (r) of the center conductor SC1 in the fine-line cable SC (h>r).
In the present embodiment having the structure described above, more than half of the outer diameter portion (d) of the center conductor SC1 in the fine-line cable (the cable-shaped signal transmission medium) SC is held by the contact engaging parts 11b, thereby achieving an excellent holding power for the fine-line cable SC
Still further, in the present embodiment, as depicted particularly in FIG. 11, a height (h′) from the cable mounting surface 13a described above to a rising end edge (an upper end edge) of the first inclined surface 11c1 of the guide inclined surface 11b is set longer than the diameter (r) of the center conductor SC1 in the fine-line cable (the cable-shaped signal transmission medium) SC (h′>r).
With this structure, more than half of the outer diameter portion (d) of the center conductor SC1 in the fine-line cable (the cable-shaped signal transmission medium) SC is held by the first inclined surfaces 11c1 thereby excellently holding the fine-line cable SC.
Still further, as depicted particularly in FIG. 7, in the conductive contact 13 in the present embodiment, a terminal edge part 13b on a rear end side of the conductive contact 13 in an extending direction (the vertical direction in FIG. 7) is disposed within a range in a fore-and-aft direction in which the contact engaging parts 11b extend as described above. More specifically, the terminal edge part (a lower end part in FIG. 7) 13b of the conductive contact 13 is disposed at a position drawn from the rear end part (a lower end part in FIG. 7) 11d of the contact engaging part 11b to a slightly forward side (an upper side in FIG. 7).
With this structure, the contact engaging parts 11b are arranged so as to be adjacent to each other over the overall length of the rear end portion including the terminal edge part 13b of the conductive conductor 13, that is, the part where the center conductor SC1 of the fine-line cable (the cable-shaped signal transmission medium) SC. Therefore, a contact between the terminal edge part of the conductive contact 13 and another member can be avoided, and electrical insulation can be excellently achieved.
Still further, at the terminal portion at the rear end portion of the conductive contact 13 in the present embodiment, as depicted particularly in FIG. 7, a dimension of the conductive contact 13 in a width direction, that is, a dimension in a contact width direction (the connector longitudinal direction) orthogonal to an extending direction, is narrowed, and a width-direction dimension of the terminal edge part 13b at the narrowed rear end portion is set as a terminal width (t1). The narrowed terminal width (t1) in the conductive contact 13 is formed so as to be shorter than the minimum width (W1) between the paired adjacent contact engaging parts 11b on the cable mounting surface 13a where the center conductor SC1 of the fine-line cable (the cable-shaped signal transmission medium) SC described above is mounted (t1>W1). The terminal part at the rear end portion of the conductive contact 13 having the terminal width (t1) with the width dimension thus narrowed extends to the terminal edge part 13b as deviating inwardly from the guide inclined surface 11c of the contact engaging part 11b described above.
As such, with the terminal portion at the rear end portion of the conductive contact 13 having a narrowed structure, the terminal edge part 13b at the rear end portion of the conductive contact 13 can be easily cut out, thereby improving productivity. That is, when the plurality of conductive contacts 13 are mounted at the same time, as exemplarily depicted in FIG. 13 to FIG. 15, it is effective to integrally manufacture all of the plurality of conductive contacts 13, setting one conductive contact 13 in a state of coupling to another conductive contact 13 via a carrier 13c, and then collectively mounting all of the plurality of conductive contacts 13. In this case, as described above, with the terminal portion of the conductive contact 13 on the rear end side being narrowed, all of the conductive contacts 13 are simultaneously mounted, and then cutting-out at the terminal edge part 13b of the conductive contact 13 on the rear end side can be easily made by folding or the like.
In particular, in the present embodiment, a groove-shaped notch 13d extending in a plate width direction is formed at the terminal portion at the rear end portion of the conductive contact 13 narrowed as described above. Therefore, cutting out the conductive contact 13 at the terminal edge part 13b can be easily made along the notch 13d, thereby allowing the plurality of conductive contact 13 to be collectively manufactured and mounted and improving productivity.
In particular, in the second embodiment, with the use of the ground bars CC3, there is a possibility that the ground bars CC3 and the conductive contact 13 may make contact with each other to cause a short circuit. However, an arrangement is made in which a contact engaging part 11b is adjacent over an entire terminal edge part 13b of the conductive contact 13 on a rear end side, thereby making it possible to reliably preventing the situation as described above.
Next, a plug connector 10′ according to a third embodiment depicted in FIG. 18 to FIG. 25 is described. Components corresponding to those in the first embodiment described above are provided with the same reference characters with a symbol “′” and basic detailed description thereof is omitted, and different structures are mainly described herein.
Similarly to the embodiments described above, each of these conductive contacts 13′ has a cable mounting surface 13a′ where the center conductor SC1′ with the center-side insulator SC4 of the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′ stripped, and the cable mounting surface 13a′ is buried so as to be exposed to an upper surface of an insulating housing 11′. On the other hand, in the present embodiment, a rear end supporting part 13f extends rearward from the cable mounting surface 13a′. This rear end supporting part 13f is configured to extend rearward in a state of falling by one stage with a step from the cable mounting surface 13a described above and be buried inside the insulating housing 11′ so as to crawl from the cable mounting surface 13a′ to the inside of the insulating housing 11′.
The rear end supporting part 13f forming a part of the conductor contact 13′ is covered from above with a part of the insulating housing 11′. The part of the insulating housing 11′ covering the rear end supporting part 13f includes a contact engaging part 11b′ for holding the conductor contact 13′ and a part coupling adjacent paired contact engaging parts 11b′ together. That is, while the contact engaging part 11b′ is provided integrally with the insulating housing 11′ also in the present embodiment, a shape with an approximately mountainous-shaped sectional shape continuing in a fore-and-aft direction (a vertical direction in FIG. 21) is adopted for the contact engaging part 11b′ in the present embodiment, and a lower-end corresponding part of a guide inclined surface 11c′ forming the approximately mountainous-shaped inclined surface part is disposed so as to cover, from above, a part of the surface of the rear end supporting part 13f of the conductive contact 13′ describe above, more specifically, both end edge parts in a width direction on the surface of the rear end supporting part 13f. Also, the lower-end corresponding parts of the paired adjacent contact engaging parts 11b′ are integrally coupled together by a part of the insulating housing 11′, and the integrally coupled part is disposed so as to cover, from above, a center part in the width direction on the surface of the rear end supporting part 13f described above.
The structure in which a part of the conductive contact 13′ is buried inside of the insulating housing 11′ as described above is made with an arrangement relation in which the arrangement pitch of the fine-line coaxial cables (the cable-shaped signal transmission medium) SC′ and the conductive contacts 13′ is narrowed and, correspondingly, adjacent contact engaging parts 11b′ are close to each other. That is, in the present embodiment, correspondingly to the narrowed pitch structure described above, the adjacent contact engaging parts 11b′ are close to each other and, accordingly, the guide inclined surfaces 11c′ are integrally coupled with a part of the insulating housing. An upper surface of a coupling part of the insulating housing 11′, that is, an integrally coupling part of the guide inclined surfaces 11c′, serves as a cable mounting surface 11e.
On the surface of the cable mounting surface 11e provided on an insulating housing 11′ side, a center-side insulator SC4 covering the enter conductor SC1′ of the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′ is mounted. On the surface of the cable mounting surface 13a′ on a conductive contact 13′ side described above, the center conductor SC1′ of the fine-line coaxial cable SC′. These cable mounting surfaces 11e and 13a′ are formed so as to continue in a flat surface shape without a step. With the structure having this flat surface shape, the fine-line coaxial cable SC′ can be stably mounted.
According to this structure of the present embodiment, the conductive contact 13′ can be more prevented from being peeled off. That is, in the present embodiment, as the adjacent fine-line coaxial cables (the cable-shaped signal transmission medium) SC′ are arranged with a narrower pitch, a space for disposing the conductive contacts 13′ is narrowed, and therefore a fixing means (refer to FIG. 12) protruding outwardly from an end edge part of the conductive contact 13′ in a width direction is not provided. Thus, a holding strength of the conductive contact 13′ may be decreased. However, in the present embodiment, since the rear end supporting part 13f of the conductive contact 13′ is disposed so as to be buried in the insulating housing 11′, the rear end supporting part 13f of the conductive contact 13′ and the conductive contact 13′ as a whole are held with a sufficient strength, thereby more preventing peeling-off from the insulating housing 11′.
Note that, as with the embodiments described above, on a front edge side portion (an upper end side portion in FIG. 19) of the conductive contacts 13′, fit-in contact parts 13e′ (refer to FIG. 26) elastically making contact with conductive contacts on a receptacle connector side are disposed so as to form a multipolar electrode shape. Also, to the rear end supporting part 13f of the conductive contact 13′, a carrier 13c′ collectively coupling all of the plurality of conductive contacts 13′ via a notch 13d′ for cutting-out provided at a terminal edge part of the rear end supporting part 13f is continuously provided.
Here, the guide inclined surface 11c′ of the contact engaging part 11b′ in the present embodiment is raised upwardly from the cable mounting surface 11e at a relatively mild angle, and a distance between adjacent paired guide inclined surfaces 11c′ continuously increases in a rising direction. Here, as depicted particularly in FIG. 25, a distance (W) between the adjacent paired guide inclined surfaces has a minimum width (W4) narrowest at a position along the surface of the cable mounting surface 11e. Also, the minimum width (W4) between the contact engaging parts 11b′ is set shorter than an outer diameter dimension (d′) of the center-side insulator SC4 of the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′ described above (W4<d′).
Furthermore, the distance (W) between the paired guide inclined surfaces has a maximum width (W5) at a position of a maximum height (h1) rising from the cable mounting surface 11e described above. Also, the maximum distance (W5) between the guide inclined surfaces 11c′ is set longer than the outer diameter dimension (d′) of the center-side insulator SC4 of the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′ (W5>d′).
With this structure being adopted, the center-side insulator SC4 of the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′ is easily received through a portion where paired contact engaging parts 11b′ form the maximum width (W5), and the center-side insulator SC4 is then inserted onto the cable mounting surface 11e as being smoothly guided along the surfaces of both of the guide inclined surfaces 11c′. Thus, the operation of mounting the fine-line coaxial cable SC′ can be stably performed by using the contact engaging parts 11b′. Therefore, operations at the time of mounting the fine-line coaxial cables SC′, such as positioning, can be easily and accurately performed, bringing efficiency to the mounting operation.
Furthermore, as described above, the minimum width (W4) between adjacent paired contact engaging parts 11b′ along the surface of the cable mounting surface 13e is set shorter than the outer diameter dimension (d′) of the external conductor SC2′ of the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′ (W4<d′). Therefore, the fine-line coaxial cable SC′ can be more accurately positioned. Even when the conductor contacts 13′ are arranged with narrow pitches, similar operation and effect can be achieved, thereby improving productivity.
On the other hand, as described above, when the distance (W) between adjacent paired guide inclined surfaces 11c′ is minimum on the cable mounting surface 11e and is set shorter than the center-side insulator SC4 of the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′ (W4<d′), the distance (W) between the guide inclined surfaces 11c′ at the height position corresponding to a diameter (r′) of the center-side insulator SC4 of the fine-line coaxial cable SC′ is formed so as to be approximately equal to the maximum width (W5) described above.
Furthermore, in the present embodiment, the minimum width (W4) between adjacent paired guide inclined surfaces 11c′ described above is set to be shorter than a width dimension (W7) of the conductive contact 13′ (W4<W7). With this, the guide inclined surface 11c′ of the contact engaging part 11b′ is reliably disposed at an upper position of the conductive contact 13′, thereby excellently holding the conductive contact 13′.
Still further, even when an external force due to so-called flapping or the like is added from the fine-line coaxial cable SC′ to the conductive contact 13′ via the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′, the rear end side portion of the conductive contact 13′ to which the fine-line coaxial cable SC′ is coupled is directly held by the contact engaging part 11b′ provided to the insulating housing 11′ and the rear-end supporting part 13f buried inside the insulating housing 11′. Therefore, the conductive contact 13′ can be prevented well from being peeled off.
Furthermore, as depicted particularly in FIG. 23 and FIG. 25, from an upper end part of the guide inclined surface 11c′ of the contact engaging part 11b′ according to the present embodiment, an introduction guide surface 11f forming a vertical wall shape is continuously provided so as to rise upwardly. That is, as described above, the guide inclined surface 11c′ is raised so as to form a relatively mild first tilt angle (θ1′) from the cable mounting surface 11e, and the introduction guide surface 11f protruding upwardly so as to form a second tilt angle (θ2′=90 degrees) forming a right angle with respect to the cable mounting surface 11e is provided from an upper end part of the guide inclined surface 11c′.
Here, at the upper end portion of the introduction guide surface 11f, an initial abutting surface 11f1 inclined at an angle of approximately 45 degrees is formed. A distance between initial abutting surfaces 11f1 provided on adjacent introduction guide surfaces 11f is set a distance (W6) that is slightly longer than the maximum width (W5) between the guide inclined surfaces 11c′ described above (W6>W7).
With this structure being adopted, at an initial stage of mounting the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′, the fine-line coaxial cable SC′ is disposed so as to be easily positioned between the initial abutting surfaces 11f1 of the adjacent introduction guide surfaces 11f, thereby smoothly performing an operation of mounting the fine-line coaxial cable SC′.
Furthermore, as depicted particularly in FIG. 25, in the guide inclined surface 11c′ provided to the contact engaging part 11b′, the maximum height (h1) from the cable mounting surface 11e where the center-side insulator SC4 of the fine-line coaxial cable (the cable-shaped signal transmission medium) SC′ is set shorter than the radius (r′) of the center-side insulator SC4 of the fine-line coaxial cable SC′ (h1<r′). In the guide inclined surface 11c′ in this case, the holding power for holding the fine-line coaxial SC′ is decreased compared with that in the embodiments described above. However, in the present embodiment, as described above, the introduction guide surface 11f protruding upwardly at an approximately right angle with respect to the cable mounting surface 11e is provided, thereby stably holding the fine-line coaxial SC′.
Still further, the contact engaging part 11b′ described above is provided with a separation guide piece 11g as depicted in FIG. 28 and FIG. 30 protruding toward a rear side (a rear side in FIG. 30). This separation guide piece 11g is formed so as to form an approximately cuneal shape in a planar view, and has a function of separating both of the fine-line coaxial cables SC′ horizontally in the drawing, with a rear end portion at an acute angle in the separation guide piece 11g being inserted between both of the center-side insulators SC4 of the paired fine-line coaxial cables (the cable-shaped signal transmission medium) SC′ forming the twin coaxial cable described above.
With this structure being adopted, when the fine-line coaxial cable SC′ formed of a twin coaxial cable is mounted, both of the center-side insulators SC4 are positionally regulated by the separation guide piece 11g so as to extend in a scheduled direction. Therefore, the twin coaxial cable can be efficiently and accurately mounted, and cable breakage can be prevented.
Also, with respect to the separation guide piece 11g, as depicted particularly in FIG. 21, a terminal edge par 13b′ of a rear-end supporting part 13f forming a rear end side portion of the conductive contact 13 described above is disposed between a rear end part of the separation guide piece 11g (a lower end part in FIG. 21) and a front end part of the contact engaging part 11b′ (an upper end part in FIG. 21). In the present embodiment, the terminal edge part 13b′ is disposed at a position drawn slightly to a front side (an upper side in FIG. 21) from the rear end part of the separation guide piece 11g (the lower end part in FIG. 21). With this arrangement relation, a contact between the terminal edge part 13b′ of the conductive contact 13′ and another member, for example, the ground bar SC3′ (refer to FIG. 29 and FIG. 30) is prevented, and electrical insulation is well achieved.
With the use of the ground bars SC3′, there is a possibility that the ground bars SC3′ and the conductive contact 13′ may make contact with each other to cause a short circuit. However, as described above, an arrangement is made in which the contact engaging part 11b′ is adjacent over an entire terminal edge part 13b′ of the conductive contact 13′ on a rear end side, thereby making it possible to reliably preventing the situation as described above.
Still further, in the embodiments described above, the guide inclined surface 11c of the contact engaging part 11b is configured as a guide member for a center conductor of a cable. Alternatively, the guide inclined surface 11c may be configured as a guide for an outer perimeter surface of a cable.
wherein the insulating housing is provided with a contact engaging part covering at least a part of a rear end portion on a surface of the conductive contact exposed to the surface of the insulating housing,
the contact engaging part includes a guide inclined surface facing the cable-shaped signal transmission medium from both sides in a contact width direction perpendicular to an extending direction of the conductive contact to position the cable-shaped signal transmission medium, and
the guide inclined surface is disposed on each of both sides of the cable-shaped signal transmission medium in a pair, and the paired guide inclined surfaces are formed so as to be separated from each other in a direction of rising from a cable mounting surface where the cable-shaped signal transmission medium is mounted,
wherein the contact engaging part includes a first end surface and a second end surface, and a length of the contact engaging part extends from the first end surface to the second end surface in the extending direction,
wherein the conductive contact has a terminal edge part provided at a rear end portion of the conductive contact in the extending direction, the terminal edge part being disposed along the length of the contact engaging part between the first end and the second end, and
the terminal edge part of the conductive contact is disposed at a position drawn from the rear end part of the contact engaging part to a slightly forward side.
