Description

  The present invention relates to a connector of a type including a plurality of contact modules.

  In recent years, information communication devices, broadcast video devices, FA system control devices, medical devices, semiconductor manufacturing devices, testers, and the like have been required to process enormous amounts of information with high speed and high accuracy. Therefore, a high shield function is required for a connector applied to these devices.

  However, the connector of Patent Document 1 requires a shield member (first ground plate 14 and second ground plate 15) and a complicated shape in order to exert a shielding effect. For this reason, the number of parts is increased, and it is difficult to increase the productivity and the manufacturing cost tends to increase.

Further, the metal shield member is intended to cover the periphery of each signal contact 16, but since there are many regions where the shield member does not exist inside or outside the integrally molded product 27, it is difficult to obtain a sufficient shielding effect. .
Further, since a plurality of shield members are embedded in the insulator 28, it is difficult to reduce the size of the integrally molded product 27 (space saving is difficult). For this reason, the contact module 6 is increased in size, and as a result, the connector is increased in size.
Further, since a plurality of shield members are embedded in the insulator 28, it is difficult to increase the density of each contact module 6 (increase the number of signal contacts 16 per one contact module 6).

  Therefore, the present inventor has invented a connector for solving these disadvantages of the prior art and has applied for a patent (Japanese Patent Application No. 2007-117407). However, there is still room for improvement in this connector.

  An object of the present invention is to provide a connector that has a small number of parts, has a simple structure, is easy to manufacture, and can reliably obtain a high shielding effect even when a contact module is downsized.

Preferably, the first held surface that is continuous with the perforated end surface is held, and the second holding portion holds a second held surface that is a surface opposite to the first held surface of each contact module. .

  According to another aspect, the connector of the present invention has a plurality of contact pins, one end of which is inserted into the other connector and connected to a plurality of contacts built in the other connector, and the other end is connected to the substrate. A plurality of sandwiching plates formed in each of opposing surfaces of a plurality of sandwiching plates arranged in one direction, and at least one contact pin is sandwiched between the insulating portions of each sandwiching plate adjacent to each other. A plurality of contact modules, and a holding member that holds the contact modules in a stacked state by attaching the contact modules to a contact module group in which the contact modules are stacked in the thickness direction of each contact module. A sandwiched recess is formed on both side surfaces of the contact module, and the sandwiched recess and the It is characterized by forming a plurality of clamping projections are engaged.

  In this aspect, the holding member includes an insulating wall portion, and a first holding portion and a second holding portion that both extend in a direction substantially orthogonal to the insulating wall portion from both end portions of the insulating wall portion, When the holding member is mounted on the contact module group, the insulating wall covers a perforated end surface having an opening for projecting the contact pin formed on each contact module to the outside of the contact module, and the first holding A second held surface in which the first holding surface is continuous with the perforated end surface of each contact module, and the second holding portion is a surface opposite to the first held surface of each contact module Is preferably maintained.

Further, the clamping protrusion is formed on a surface of the first holding part facing the second holding part, and a part of the sandwiched recess is opened on the surface of the contact module facing the first holding part. The opposing surfaces of the two adjacent clamping projections may be tapered surfaces that approach the opposing surface side that faces the second holding portion side from the first holding portion side.

According to the present invention, the number of parts of the receptacle connector (Claim 1) and the plug connector (Claim 3) is small and the structure is simplified as compared with a conventional connector using a metal shield member. Furthermore, since a metal shield member is not required, the contact module can be made smaller than the prior art when the same number of contacts as the prior art connector is provided, and the contact density in the contact module can be increased. . Furthermore, since the surface area of the conductive layer can be increased, the shield effect of the connector can be enhanced. Therefore, the connector to which the present invention is applied can transmit signals at high speed.
In addition, when the holding member is attached to the contact module group, the holding protrusions of the holding member engage with the holding recesses formed on both side surfaces of the contact module. Therefore, each clamping plate constituting the contact module can be reliably joined, and each clamping plate can be prevented from separating after joining (because each clamping plate is pressed in the joining direction from the outside of the contact module, Even if the force for joining the sandwiching plates of the contact module itself becomes weak, the joining state of each sandwiching plate can be reliably maintained). Therefore, it is possible to reliably obtain a high shielding effect.
Furthermore, since the pinching protrusions are provided, the contact module group and the holding member can be mounted only when both directions are correct, and erroneous fitting can be reliably prevented.
Further, the setting position of the holding protrusion in the holding member is determined according to the setting position of the holding recess in the contact module. That is, the pinching protrusion can be used as an identification mark for identifying the specification (thickness or the like) of the contact module corresponding to the holding member. For this reason, it is possible to prevent erroneous attachment of contact modules having different specifications (thickness, etc.) to the holding member.

  According to the second or fourth aspect of the invention, when the holding member is attached to the contact module group, the insulating wall portion of the holding member covers the perforated end surface of the contact module group, so that the insulating property of the perforated end surface can be improved. it can.

  According to the fifth aspect of the present invention, when the holding protrusions of the holding member are engaged with the respective holding recesses of the contact module group, the respective holding recesses corresponding to the opposing surfaces (taper surfaces) of the adjacent holding protrusions. It functions as a guide surface that guides to the insulating wall side. Therefore, the assembly operation of the contact module group and the holding member can be easily performed. Further, when the contact module group and the holding member are assembled, each contact module is held in a correct position with respect to the holding member.

  According to the sixth aspect of the present invention, when each of the clamping protrusions engages with the corresponding sandwiched recess, the contact module group and the holding member are not easily disengaged, and the contact module group is in contact with the holding member. I will not play.

  According to the seventh aspect of the present invention, the contact module group and each direction of the holding member (particularly the direction connecting the first holding portion and the second holding portion) after engaging each holding protrusion with the corresponding holding recess. It is possible to effectively reduce backlash and detachment.

  According to the invention of claim 8, since each guide key engages with a guide groove formed between adjacent contact modules, it is possible to prevent positional deviation and inclination in the holding member of the contact module group, It is possible to keep the contact module group in a regular position. In addition, since the guide key and the guide groove function as a guide when the contact module group is inserted into the holding member, it is possible to improve workability and increase the yield.

According to the ninth aspect of the present invention, since it is not necessary to form the guide key and the holding protrusion by shifting their positions (in the thickness direction of the contact module), the guide groove engaging with the guide key and the holding protrusion, It is possible to reduce the thickness and size of the contact module in which the sandwiched recess is formed.
Furthermore, if the guide key and the clamping protrusion are not formed integrally, the clamping protrusion cannot be smoothly fitted into the clamping recess unless the clearance between the clamping protrusion and the clamping recess is set large. If comprised like a claim, the protrusion for clamping can be smoothly and accurately fitted to the recessed part for clamping.

Since the recesses 136, 137, 149, and 150) are formed, the surface areas of the conductive layer portions 135, 148, and 160 are extremely large.
Furthermore, in the present embodiment, since the sandwiching plates 133, 134, and 138 (conductive layer portion and insulating portion) constituting the contact modules 121, 122, 131, and 132 are resin molded products, the insulating portion recesses and the contact holding portions are provided. Even if it has a complicated shape part such as a groove, it can be easily produced without reducing productivity.

  Moreover, since a metal shield member is not embedded in the contact modules 121, 122, 131, 132, the number of parts can be reduced compared to the conventional connector, and when the same number of contacts as the conventional connector is provided, The contact modules 121, 122, 131, and 132 can be made smaller than the prior art.

In addition, since the engagement key 183 and the engagement key 184 are formed on the holding member 110 and the holding member 175, and the key groove 135E and the key groove 148E are formed on the contact module group 116 and the contact module group 172, the following advantages are obtained. .
That is, when the holding member 175 is attached to the contact module group 172 (and the holding member 110 is attached to the contact module group 116), the pair of engagement keys 183 and the pair of engagement keys 184 correspond to the contact modules 131 and 132. The key grooves 148E and 135E are fitted (the front ends of the engagement keys 183 and 184 are in contact with each other as shown in FIG. 21). Then, the opposing surfaces of the clamping plates 133, 134, and 138 constituting the contact module 131 (contact module 121) and the opposing surfaces of the clamping plates 133 and 134 that constitute the contact module 132 (contact module 122) (conducting layer portions and insulating layers). Each of the contact modules 131 (contact module 121) and the contact module 132 (contact module 122) are included in each of the clamping plates. Since the connection between the conductive layer portions is maintained, a high shielding effect can be surely exhibited.
Further, since the side surfaces of the respective engagement keys 183 and 184 are tapered surfaces that are inclined from the lower side to the upper side, when the respective engagement keys 183 and 184 are engaged (fitted) with the corresponding key grooves 148E and 135E. The contact module group 172 and the holding member 175 (contact module group 116 and the holding member 110) are firmly engaged (not easily detached), and the contact module group 172 is in contact with the holding member 175 (the contact module group 116 is the holding member). 110) (particularly the effect on the roll and the vertical direction is remarkable).
Further, the side surfaces of the respective engagement keys 183 and 184 are tapered surfaces that are inclined from the rear to the front, and as shown in FIG. 21, the distance between the opposing surfaces of the adjacent engagement keys 183 and 184 is from the rear to the front. It is getting smaller. Therefore, when the engagement keys 183 and 184 of the holding member 175 (holding member 110) are engaged with the key grooves 135E and 148E of the contact module group 172 (contact module group 116), the adjacent engagement keys 183 and 184 are adjacent. The key surfaces 135E and 148E corresponding to the opposite surfaces (taper surfaces) function as guide surfaces that guide the vertical portions 176 (vertical portions 111). Therefore, it is possible to easily assemble the contact module group 172 and the holding member 175 (the contact module group 116 and the holding member 110), and further, the contact module group 172, the holding member 175, the contact module group 116, and the holding member. When 110 is assembled, each contact module 121, 122, 131, 132 is guided and held at the correct left-right position with respect to the holding member 175 and the holding member 110.
In addition, in this embodiment, the engagement key 183 and the engagement key 184 are provided at predetermined intervals on the lower portion (lower piece portion 178, contact module holding portion 113A) of the holding member 175 and the holding member 110, and the upper portion (upper piece portion). 177, not provided in the contact module holding part 112A). Therefore, when the contact module group 116 and the contact module group 172 are misoriented in the vertical direction or the key grooves 135E and 148E are not formed at intervals corresponding to the engagement keys 183 and 184, the holding member 110 is used. Therefore, the contact module group 116 and the holding member 110 and the contact module group 172 and the holding member 175 can be reliably prevented from being erroneously mounted. Even if the engagement keys are formed on the upper portions of the holding member 175 and the holding member 110 with different sizes, shapes, positions, and intervals from the lower portions, the same effect of preventing erroneous insertion can be obtained.
Further, since the holding member 175 and the holding member 110 are provided with a total of eight guide keys 180, 182, 188 and 189, the guide keys 180, 182, 188 and 189 are connected to the upper edges of the contact module groups 116 and 172, respectively. By engaging the V-shaped grooves (guide grooves) formed by the portion 135F, the lower edge portion 135G, the upper edge portion 148F, and the lower 148G, the holding member 175 and the holding member 110 are brought into contact module group 172 and contact module group. It is possible to slide easily while positioning in the front-rear direction with respect to 116. Therefore, mounting (sliding backward) and removing (sliding forward) the holding member 175 and the holding member 110 with respect to the contact module group 172 and the contact module group 116 can be easily performed.
