Description

[Detailed description of the invention] A. Field of industrial application The present invention relates to a terminal mounting structure for an octal pin type electrical socket for control equipment, etc., in which a base part is fitted into a cover part having a socket seat and a terminal block on the surface. .

B. PRIOR ART The one shown in FIG. 5 is an electric socket for control equipment according to the first conventional example, which is attached to a DIN rail, etc., and consists of a cover part C having a socket seat 1 on its surface, and a base part D, which is attached to the DIN rail. When assembling, place the cylindrical socket fitting 4 into the vertical hole 3 of the socket seat 1 with the cover part C facing backwards, place the perforated lead plate 5 extending from the lower end of the socket fitting 4 on the back side of the cover part C, and attach the base. Fit the hexagonal nut 16 into the hexagonal hole 15 of part D so that it will not fall even if it is facing downward, connect the base part D to the cover part C from above, and screw the terminal screw 12 into the hexagonal nut 16. The lead plate 5 is fixed to the back surface of the cover part C by attaching the hexagonal nut 16 to the hexagonal hole 15 to prevent the hexagonal nut 16 from falling from the base part D during assembly as described above. It took a special effort to put it on. What is shown in FIG. 6 is the main part of Embodiment 2, in which a patch plate 18 with a female thread 17 cut out is caulked with a pin 19 or the like on the back side of the perforated end of the lead plate 5 of the socket fitting 4. The lead plate 5 was placed against the reverse side of the cover part C, the base part D was attached, and the terminal screw 12 was screwed into the female thread 17. In this second embodiment, there is no fear that the backing plate 18 will fall during assembly, but special steps were required to process the female threaded portion 17 and caulk the backing plate 18.

C. Problems to be solved by the invention The present invention has been proposed by focusing on the problems of the prior art examples 1 and 2 mentioned above. To provide a terminal mounting structure for an electric socket or the like, which does not require special processing or mounting structure on a nut part, and allows efficient assembly work by turning over a cover part and placing a base part on it.

D. Means for Solving Problems As illustrated in FIGS. 1 to 4, the present invention provides a fitting type terminal, such as a socket fitting 4, which enters the hole 3 of the cover part C and is exposed on the surface side of the cover part. The lead plate 5 extending from the lower end of the lead plate is fitted along the back surface of the cover part, and the perforated end 5a of the lead plate is fitted into the rectangular recess 8 on the back surface of the cover part. The square plate nuts 6 are overlapped and fitted, and the upper surface 10 of the base portion D formed separately from the cover portion C is applied to the back surface of the cover portion to fit and connect the cover portion C to the base portion D. The problem was solved by screwing the cover part surface square plate nut 6.

E. Function When the socket fitting 4 is attached to the upper surface 10 of the base part D and the cover part C is fitted to the base part D, if the socket fitting 4 is deviated from the predetermined position direction, the socket fitting 4 is inserted into the hole 3 of the cover part C. Since it is difficult to insert the metal fitting 4, assemble the cover part C as shown in Figure 1.
This is done by turning it over and placing the base part D on it. In this case, first insert the socket fitting 4 into the hole 3 from the back side of the cover part C. Then, the lead plate 5 of the socket fitting 4 is placed between the jetties 7 on the back side of the cover part. In this way, the perforated end 5a of the lead plate 5 fits into the rectangular recess 8. Then, the square plate nut 6 is stacked on the perforated end 5a and fitted into the rectangular recess 8. Next, the base part D is fitted and coupled to the cover part C so that the upper surface 10 of the base part D (facing downward in FIG. 1) is placed on the back surface of the cover part C. At this time, the jetty 7 is fitted into the groove 9 of the base portion D. In this state, the square plate nut 6 is surrounded by the rectangular recess 8 and is prevented from escaping by the upper surface 10 of the cover portion D. Therefore, from the surface of the cover portion C, the perforated end 5a of the lead plate 5 terminal screw 12
When inserted and screwed, the screw is screwed into the square plate nut 6, and the perforated end 5a of the lead plate 5 is connected to the cover part C.
Fixed against. This electrical socket is used by attaching the base part D to a DIN rail or the like, and inserting a plug for a control device or the like into the socket part on the surface of the cover part C.

F. Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 4. C and D are a trapezoidal cover part and a base part, respectively. The cover portion C has a socket seat 1 at the center of the surface. A hole 3 is formed vertically through the socket seat 1 from the front to the back, and a cylindrical socket fitting 4, which is one of the mating terminals, is inserted into the hole 3 from below. There is an exposed opening on the surface side of the cover. Reference numeral 5 denotes a lead plate that integrally extends laterally from the lower end of the socket fitting 4, and has a perforated end portion 5a with a through hole provided in the center. Reference numeral 7 denotes a jetty protruding from the back surface of the cover part C, and a square recess 8 is formed between the T-shaped end 7a, the cross-shaped part 7b, and the stepped part 7c of the jetty. This rectangular recess 8 reaches the surface of the cover portion C and forms a rectangular opening. This square pit 8
A perforated end 5a of a lead plate 5 extending along the back side of the cover portion C is fitted into the hole, and a square plate nut 6 is fitted into the rectangular recess 8 over this. Reference numeral 9 denotes a concave groove provided on the upper surface 10 of the base portion D, which is formed to match the entire shape of the jetty 7, and is formed to fit the entire shape of the jetty 7.
When the jetty 7 is fitted into the groove 9, the jetty 7 is fitted into the groove 9. Reference numeral 11 is an escape hole to prevent the tip of the terminal screw 12 from getting caught. Reference numeral 13 is a relief hole on the side of the base part D, and when the base part D and the cover part are fitted, it is inserted into the square hole 14 on the cover part D side. It is a locking claw. In the above configuration, the square plate nut 6 and the perforated end 5 of the lead plate 5
a is the upper surface 1 of the stepped portion 7 and the base portion D in the rectangular recess 8;
It is clamped and fixed between 0 and 0.

Effects of the invention The present invention is as described above, in which the perforated rectangular end of the lead plate of the mating terminal is fitted into the rectangular recess on the back of the cover part, and a square plate nut is fitted over this. ,
Since the base part is fitted into the cover part and the terminal screw is screwed into the square plate nut, the square plate nut must be inserted into the special hole during the assembly work, which is performed by turning the cover part over and overlapping the base parts. There is no need to fix it, and there is no need for special work such as forming nuts or caulking, so you can work efficiently.
It also has the advantage of being inexpensive to manufacture.
