In the present embodiment described above, as shown in FIG. 10 and FIG. 11, the periphery of each signal contact 65B, 65C, 65E, 65F is completely covered with the insulating portion 43 and the insulating portion 55, and the periphery thereof is electrically conductive. It is completely covered by the recessed portions 36, 37, 49, 50 for the insulating portions provided in the layer portions 35, 48. Therefore, the signal contacts 65B, 65C, 65E, and 65F are reliably shielded by the inner surfaces of the recesses 36, 37, 49, and 50 for each insulating portion (the noise that is picked up from the outside and is generated by itself during transmission). Can be very effectively prevented from leaking outside). Therefore, the connector 10 having excellent shielding characteristics and capable of high-speed transmission is obtained.
Further, conductive layer portions 35 and 48 are formed on the entire surfaces of the sandwich plate 33 and the sandwich plate 34, and a recess (for an insulating portion) is formed on the surface (inner side surface) of the conductive layer portions 35 and 48 facing the other sandwich plate. Since the recesses 36, 37, 49, 50) are formed, the surface areas of the conductive layer portions 35, 48 are extremely large.
Further, in the present embodiment, since the sandwiching plates 33 and 34 (conductive layer portion and insulating portion) constituting the contact module 31 are resin molded products, complicated shape portions such as a concave portion for insulating portion and a contact holding groove are provided. Even if equipped, it can be easily produced without reducing productivity.

  In addition, since the metal shield member is not embedded in the contact module 31, the number of parts can be reduced as compared with the conventional connector, and when the same number of contacts as the conventional connector is provided, the contact module 31 is used in the prior art. It can be made smaller.

  Further, since the contact modules 31 constituting the contact module group 72 are separated from each other, for example, even when external noise or internal noise occurs in one contact module 31, this noise constitutes the contact module group 72. It is difficult to reach other contact modules 31. Therefore, there is little possibility that the transmission characteristics of other contact modules 31 are adversely affected by the noise.

  In addition, since each contact module 31 is integrated using the holding member 75 instead of the housing which is necessary in the conventional connector, it can be said that the manufacture (assembly) is easy also in this respect.

  Further, the end contacts 40, the end storage portion 45, the storage portion 52, the connecting portion 53, the end storage portion 57, and the communication portion 58 provided in the holding plate 33 and the holding plate 34 are provided with the ground contacts 65 </ b> A, 65 </ b> D, Since the signal contacts 65B, 65C, 65E and 65F are sandwiched, the ground contacts 65A and 65D and the signal contacts 65B, 65C, 65E and 65F can be firmly held by the sandwich plate 33 and the sandwich plate 34 and manufactured ( Assembly) is easy and productivity is high.

The In addition, the contact end portions 316 of the contact pins 315A, 315B, 315C, 315D, 315E, and 315F pass through the corresponding through holes 336 of the vertical portion 331 and protrude rearward of the vertical portion 331.
When the connecting rod 280 and the holding member 330 are coupled to the contact module group 320 in this way, gaps are formed between the left and right contact modules 230 and the center contact module 230, respectively, as shown in FIG.
When the press-fit terminals 317 of the contact pins 315A, 315B, 315C, 315D, 315E, and 315F of the plug connector 300 are driven into the through holes of the substrate CB2 (see FIGS. 62 and 63), the ground contact pins 315A, 315C, and 315E The press-fit terminal 317 is connected to the ground pattern on the substrate CB2, and the press-fit terminal 317 of each signal contact pin 315B, 315D, 315F is connected to the circuit pattern on the substrate CB2.

As shown in FIG. 63, the receptacle connector 220 and the plug connector 300 configured as described above are covered with the receptacle connector holding portion 334 of the holding member 330 on the upper surface of the upper piece portion 292 of the holding member 290, and the receptacle connector holding portion 335 is placed on the lower piece portion. 293, the contact end portions 316 of the ground contact pins 315A, 315C, and 315E of the plug connector 300 are fitted into the fitting holes (opening recess 237, opening recess 249, and opening recess 261) of the receptacle connector 220. In addition, the spring-like bifurcated portions 271 of the corresponding ground contacts 270A, 270C, 270E are connected to the respective spring-like bifurcated portions 271 while being elastically deformed inside the receptacle connector 220. Similarly, the contact end portions 316 of the signal contact pins 315B, 315D, and 315F of the plug connector 300 are fitted into the fitting holes (opening recess 237, opening recess 249, and opening recess 261) of the receptacle connector 220, and the receptacle connector 220 is inserted. Are connected to each spring-like bifurcated portion 271 while elastically deforming the spring-like bifurcated portion 271 of the corresponding signal contact 270B, 270D, 270F.
Accordingly, the ground contacts 270A, 270C, 270E and the ground contact pins 315A, 315C, 315E are electrically connected to the ground pattern of the board CB1 on the receptacle connector 220 side and the ground pattern of the board CB2 on the plug connector 300 side, The signal contacts 270B, 270D, and 270F and the signal contact pins 315B, 315D, and 315F are electrically connected to the circuit pattern of the board CB1 on the receptacle connector 220 side and the circuit pattern of the board CB2 on the plug connector 300 side.

In the present embodiment described above, as shown in FIG. 73, the periphery of each signal contact 270B, 270D, 270F and the signal contact pins 315B, 315D, 315F is completely covered by the insulating portion 245 and the insulating member 260. The periphery is completely covered by the recesses 233, 234, and 235 for the insulating portion that are recessed in the conductive layer portion 232. Further, the entire surface (outer side surface) of the sandwiching plate 231 is configured by the conductive layer portion 232, and a recess (insulating portion recess portion 233) is formed on the surface (inner side surface) of the conductive layer portion 232 facing the other sandwiching plate 231. 234, 235) (the surface area of the inner surface of the conductive layer portion 232 is extremely large), the signal contacts 270B, 270D, 270F and the signal contact pins are formed by the recesses 233, 234, 235 for the insulating portions. 315B, 315D, and 315F are reliably shielded (it can be very effectively prevented from picking up external noise and leaking noise generated by itself during transmission). Therefore, the connector 200 having excellent shielding characteristics and capable of high speed transmission is obtained.
In addition, since the contacts forming the differential pair have the same specifications (the same material and the same shape (length)), it is possible to reduce the possibility of a difference in transmission characteristics between the differential pairs. Specifically, it is possible to suppress signal time deviation (jitter) and waveform waviness (ringing), and to improve signal quality by a synergistic effect with excellent shielding characteristics.

  Further, as in the second embodiment, not only the contact module 230 of the receptacle connector 220 but also the contact module 310 of the plug connector 300 are separated from each other. There is little possibility that external noise entering the contact module or internal noise generated by the contact module will adversely affect the transmission characteristics of other contact modules.

Further, since the sandwiching plate 231 constituting the contact module 230 and the contact module 310 is a resin molded product, even if it has a complicated shape portion such as a recess for an insulating portion or a contact holding groove, productivity is not reduced. Easy to produce.
In addition, since the metal shield member is not embedded in the contact module 230 and the contact module 310, the number of parts can be reduced as compared with the conventional connector, and when the same number of contacts as the conventional connector is provided, the contact is reduced. The module 230 and the contact module 310 can be made smaller than the conventional technology.
In addition, since each contact module 230 and contact module 310 are integrated by using the holding member 290 and the holding member 330 instead of the housing necessary for the conventional connector, manufacturing (assembly) is easy also in this respect. It can be said that.
Also, an opening recess 237, an end storage portion 238, and a communication portion 239 provided in the sandwiching plate 231; an opening recess 249 provided in the insulating portion 245; an end storage portion 250, a communication portion 251, and a communication portion 252; The contacts 270A, 270B, 270C, 270D, 270E, 270F and the contact pins 315A, 315B, 315C, 315D, 315E, 315F are sandwiched by the opening recess 261 and the end storage portion 262 that are recessed in the insulating member 260. The contacts 270A, 270B, 270C, 270D, 270E, 270F, and the contact pins 315A, 315B, 315C, 315D, 315E, and 315F can be firmly held by the sandwiching plate 231 and the insulating member 260 and are easy to manufacture (assemble). And high productivity.
Further, since the through hole 336 is formed in the vertical portion 331 of the holding member 330, the contact pins 315A, 315B, 315C, 315D, 315E, and 315F) can be easily held at predetermined positions (alignment can be easily ensured). ). Similarly, since the vertical portion 291 of the holding member 290 has a through hole 294, the contact pins 315A, 315B, 315C, 315D, 315E, and 315F can be easily guided accurately into the receptacle connector 220 (each contact 270A, 270B, 270C, 270D, 270E, 270F).

As mentioned above, although this invention was demonstrated based on 3rd Embodiment, it can implement, giving various deformation | transformation.
For example, as in the modification shown in FIGS. 77 and 78, two insulating members 345 may be disposed between the left and right clamping plates 231.
Similar to the conductive layer portion 232, the insulating member recesses 233, 234, 235, the opening recess portion 237, the end storage portion 238, and the communication portion 239 are formed on both side surfaces of the insulating member 345. An insulating part 245 is fitted on the surface. Further, a front step 346 is formed at the front of the upper end of the insulating member 345, and a pair of left and right front engaging projections 347 protrude from the upper surface of the front step 346. In addition, a rear engagement recess 348 is formed in the vicinity of the upper end portion of the rear end surface of the insulating member 345, and a key groove 349 is formed in the lower end portion of the front end surface of the insulating member 345.
Between the fitting recess 255 of the left holding plate 231 and the left fitting recess 255 of the left insulating member 345, and the left fitting of the right fitting recess 255 and the right insulating member 345 of the left insulating member 345. Insulating members 260 are respectively fitted between the concave portions 255 and between the fitting concave portion 255 of the right holding plate 231 and the right fitting concave portion 255 of the right insulating member 345, and adjacent holding plates 231. Each of the contacts 270A, 270B, 270C, 270D, 270E, and 270F is sandwiched between the insulating member 260 and the adjacent insulating member 345 and the insulating member 260.
Although not shown in the drawing, the rear portion of the contact module group configured by arranging a plurality of contact modules 340 having such a structure is engaged with the rear engagement recess 241 and the rear engagement recess 348. It is coupled by a connecting rod having a protrusion, and the front part of the contact module group is coupled by a holding member having an engagement protrusion corresponding to the key groove 243 and an engagement groove corresponding to the front engagement convex part 347. If a gap is formed between adjacent contact modules 340, the receptacle connector and the plug connector are completed.

77 and 78, the contact group of six sets (one set is made up of contacts 270A, 270B, 270C, 270D, 270E, and 270F arranged in the vertical direction) is divided into four clamping plates (clipping plates 231; In addition, since the structure is sandwiched by using the insulating member 345 and the two insulating portions 245) and the three insulating members 260, two sets of contacts are included in the two sandwiching plates 231 and one insulating member 260. There are the following advantages over the contact module 230 sandwiched between:
First, in the contact module 230, for example, a total of six clamping plates 231 are required to sandwich six sets of contacts, but in this modification, four are sufficient. That is, the number of parts, the number of assembling steps, and the processing time for processes such as plating performed for each part can be reduced, so that the productivity can be improved and the manufacturing cost can be reduced.
Secondly, the contact module 340 includes a sandwiching plate 231, an insulating member 345 that is thicker than the sandwiching plate 231 and has higher mechanical strength, and a sandwiching plate that includes two insulating portions 245. Compared with the contact module 230, the mechanical strength of the contact module and the contact module group can be increased.
77 and 78, the thickness of the conductive layer portion 232 on both the left and right side portions of the sandwiching plate constituting the contact module 340 is smaller than half the plate thickness of the insulating member 345. If the holding member for the receptacle connector and the holding member for the plug connector have no left and right side walls, all the contacts 270A, 270B, 270C, 270D, 270E, 270F and the contact pins 315A, 315B, 315C, 315D It is possible to arrange a plurality of plug connectors or receptacle connectors in the left-right direction with the same distance in the left-right direction of 315E, 315F.
Note that the receptacle connector and the plug connector may be configured with one or three or more insulating members 260 positioned between the left and right clamping plates 231.

Further, the modification shown in FIG. 79 can be implemented.
On the inner side surface of the conductive layer portion (conductive layer) 232 ′ of the receptacle connector 350 of this modified example, an opening concave portion 237 that is a concave portion for holding a ground contact, an end storage portion 238, and a communication portion 239 are formed. Absent. That is, the receptacle connector 350 has only signal contacts 270B, 270D, and 270F.
Even when the ground contact is omitted as described above, if the distance between the differential pairs is adjusted to an appropriate distance by adjusting the thickness of the insulating member 260 (depth of the fitting recess 255), the gap between the differential pairs The occurrence of crosstalk can be suppressed (electromagnetic interference can be suppressed).
Of course, this modification can be applied to a plug connector.

Further, two or more signal contacts 270B, 270D, 270F and signal contact pins 315B, 315D, 315F arranged in the vertical direction between the opposing fitting protrusions 246, 247, 248 and the insulating member 260 are sandwiched. Also good. Also in this case, the contact and the contact pin that face in the left-right direction across the insulating member 260 have the same specifications.
Alternatively, the contact holding groove may be formed only in one of the two opposing conductive layer portions, or the contact holding groove may be formed only in one of the opposing insulating portion and insulating member.

  Further, in the third embodiment, the side plate of the sandwiching plate 231 and the insulating plate recesses 233, 234, 235 of the sandwiching plate made up of the insulating member 345 and the two insulating portions 245 (parts extending in parallel with the respective contacts). In the third embodiment, the insulating portion recesses 233, 234, and 235 are the portions that form the upper and lower edges.) Are all covered by the conductive layer portions 232 and 232 ′, but a part of them is covered with the conductive layer. You may implement as a shape which is not covered with a part. FIG. 80 shows an example of this, and a part (upper part) of the insulating part recess 233 is not covered with the conductive layer part 232 ″. FIG. 80 shows a modified example of the receptacle connector, but it is naturally applicable to a plug connector.

Furthermore, a contact holding groove may be provided in the side surface of the insulating member 260 instead of the sandwiching plates 231 and 231 ′ (conductive layer portions 232, 232 ′, 232 ″ and the insulating portion 245).
Further, although not shown in the drawings, the number of contacts or contact pins sandwiched between the sandwiching plate 231 and the sandwiching member 260 adjacent to each other may be any number as long as it is one or more.
Further, the insulating portion may be integrally formed (so-called two-color molding) on the conductive layer portion 232 (conductive layer portion 232 ′) using a mold.
Furthermore, after plating is formed on the entire surface of the synthetic resin material, the conductive layer portion (plating) where the insulating portion is formed may be removed, and the insulating portion may be formed on the removed portion.

Subsequently, a fourth embodiment of the present invention will be described with reference to FIGS. Note that the front-rear and left-right directions in the following description are based on the directions of the arrows in the figure.
