<Assembly process>
As shown in FIG. 3, four unit sockets 110 constitute a set of socket housings 11. The socket housing 11 in a state where the set is released is divided into four unit sockets 110. The unit socket 110 constituting the set of socket housings 11 is housed in the corresponding socket housing portion 2151 of the holder portion 210 as a single unit. Adjacent unit sockets 110 are assembled in a state in which the side walls 113 are adjacent to each other. There is no partition wall separating the side wall 113 and the side wall 113 from each other, and they are adjacent to each other in close contact. Thereby, the enlargement of the connector structure by installing a partition wall is suppressed.

A plurality of unit sockets 110 may be assembled into the corresponding socket accommodating portion 2151 of the holder portion 210 as a single unit. Or you may assemble | attach to the socket accommodating part 2151 in the unit socket 110 unit. At this time, the adjacent unit sockets 110 may be assembled sequentially from one end of the socket accommodating portion 2151 and finished at the other end. In addition, the unit socket 110 may be vacant in the socket accommodating portion 2151 when the assembly is completed.

  When the unit sockets 110 are assembled at the corresponding positions of the socket accommodating part 2151, the socket housing 11 and the holder part 210 are integrated. As a result, the fitting between the socket housing 11 and the base housing 21 is converted into the fitting between the holder part 210 to which the unit socket 110 is assembled and the cover part 230.

  As shown in FIG. 4, the holder part 210 assembled in all the places where the unit sockets 110 correspond is assembled in the holder accommodating part 2301 of the cover part 230. The holder part 210 assembled to the cover part 230 integrally constitutes the base housing 21. Thereby, the connector structure 1 by fitting the socket housing 11 and the base housing 21 is obtained.

  As shown in FIG. 4, the holder part 210 is assembled to the holder accommodating part 2301 from the upper position of the cover part 230 with the bottom face down. The guideline for alignment is the horizontal direction between the lower ends of the guide ribs 2110 and 2110 at the left and right ends of the front wall 211 of the holder portion 210 and the upper ends of the guide grooves 2312 and 2312 provided at the left and right ends of the inner surface of the front wall 231 of the cover portion 230. Is a match. Thus, the holder part 210 is in an assembly position with respect to the cover part 230 where the positions in the horizontal direction are matched.

  The holder part 210 is lowered along the guide groove part 2312 from a position where the horizontal position of the guide protrusion part 2110 of the holder part 210 and the guide groove part 2312 of the cover part 230 are aligned. As a result, the bottom surface of the bottom wall 216 of the holder unit 210 comes into contact with the top surface of the bottom wall 236 of the cover unit 230 and stops. In this way, the holder part 210 is assembled to the holder accommodating part 2301 of the cover part 230.

  In the process of assembling the holder part 210 and the cover part 230, the lock lever 2111 provided on the front wall 211 of the holder part 210 bends backward as a whole. The amount of deflection increases as the fitting progresses. When the holder part 210 is in the assembly completion position, the protrusion 2113 provided on the lock lever 2111 fits into the locking hole 2310 formed in the lock lever groove 2311 of the cover part 230. As a result, the rearward deflection of the lock lever 2111 is somewhat weakened, and the holder part 210 is held by the cover part 230 at the locking position when assembly is completed.

<Unit socket assembly process>
As shown in FIG. 6, the unit socket 110 is assembled to the holder unit 210 with the bottom face down. At this time, the holder part 210 is in a posture with the opening 2150 facing upward. FIGS. 6A and 6B are process diagrams in which the unit socket of the connector structure is fitted to the corresponding portion of the cover, where FIG. 6A is a state before fitting, FIG. 6B is a state during fitting, and FIG. Is an external perspective view showing a completed state, (D) is a bottom view of the holder.

The position where the unit socket 110 is assembled to the holder portion 210 depends on the correspondence between the guide protrusions 1120 and 1120 and the guide groove portions 2121 and 2121. The unit socket 110 differs in size depending on the number of socket contacts 12 to be mounted, and in particular, the width dimension in the left-right direction is different. Since the guide ridges 1120 are provided at the left and right ends of the rear wall 112, the intervals at which the guide ridges 1120 are provided differ depending on the number of socket contacts 12 to be mounted. Since the guide groove portion 2121 of the holder portion 210 is provided at a position corresponding to this, the interval between the guide groove portions 2121 is determined by the corresponding unit socket 110.
As a result, the unit socket 110 is assembled at the position of the corresponding socket accommodating portion 2151.

  As shown in FIG. 6, the unit socket 110 is accommodated in a corresponding socket accommodating portion 2151. The guide ridges 1120 and 1120 at the left and right end portions of the rear wall 112 of the unit socket 110 proceed downward along the guide groove portions 2121 and 2121 at corresponding positions of the holder portion 210.

  The locking piece 1123 provided on the rear wall 112 of the unit socket 110 is a cantilever having a lower end as a base end portion and an upper end as a movable portion. The entire locking piece 1123 is elastically displaced in the front-rear direction with the thick operating portion 1124 at the upper end as an action point. The locking piece 1123 at the initial stage of the assembly process is in a position where the operation portion 1124 is slightly closer to the wall side.

  As the assembly process proceeds, the outer surface of the locking piece 1123 comes into contact with the upper end of the inner surface of the rear wall 212 of the holder part 210 at a position where the lower end of the unit socket 110 is accommodated in the socket accommodating part 2151. Due to the contact, the locking piece 1123 is elastically displaced forward, which is the wall side. The displacement of the locking piece 1123 increases with the progress of the assembly process.

  When the unit socket 110 is inserted to the assembly completion position of the socket housing part 2151, the bottom surface of the unit socket 110 comes into contact with the upper surface of the bottom wall 216 of the holder part 210. At the assembly completion position, the locking piece 1123 contacts the inner side surface of the rear wall 212 of the holder part 210 with the outer surface in a tilted position, and applies a biasing force. The locking projection 1125 provided on the outer surface of the locking piece 1123 is located at the position of the corresponding locking hole 2120 provided on the rear wall 212 of the holder part 210. The locking projection 1125 is locked in the locking hole 2120, and the unit socket 110 is held at the assembly completion position of the holder unit 210.

  The unit socket 110 accommodated is extracted from the holder portion 210 by bringing the operation portion 1124 of the locking piece 1123 down to the front wall side and releasing the locking state between the locking protrusion 1125 and the locking hole 2120. . The extraction operation is performed in the reverse procedure of the assembly process. The unit socket 110 released from the locked state is removed from the socket accommodating portion 2151 by moving upward.

<Another assembly order>
As shown in FIG. 7, the unit socket 110 may be assembled to a holder part in which the holder part and the cover part are integrated. The assembling procedure of the unit socket 110 at this time is substantially the same as the operation procedure for assembling the unit socket 110 to the holder unit 210 separated from the cover unit 230. Further, the assembling procedure of the holder part 210 and the cover part 230 at this time is substantially the same as the operation procedure for assembling the holder part 210 to which the unit socket 110 is assembled to the cover part 230.
