【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an assembled state of a pressure contact connector according to an embodiment of the present invention, and FIG. 2 is a perspective view of a terminal. In the figure, the connector case 10 is provided with a hood portion 11 on the front side on the upper left side in the drawing, and a terminal holding portion 12 on the rear side on the lower right side in the drawing. Eight cylindrical portions 13 capable of inserting and holding the terminals 20 are formed in the connector case 10, and an opening 14 is formed above the rear side of the terminal holding portion 12 in the cylindrical portion 13. . On the other hand, the terminal 20 has a male fitting portion 21 formed on the front side on the upper left side in the drawing, and a pressure contact portion 22 on the rear side on the lower right side in the drawing. The pressure contact portion 22 is formed in a U-shaped cross section having an opening at the top, and a U-shaped pressure contact metal fitting 23 having an opening at the bottom is fitted and held in the central portion. The press-fitting metal fitting 23 is formed with a press-fitting slot 23a which is cut out in a slit shape from the upper side to the lower side. When the electric wire W is inserted into the same press-fitting slot 23a from above, the covering portion is cut by the end of the metal fitting. Since the conductor wire is exposed, it comes into contact with the same end portion and becomes electrically conductive. Since the same press contact slot 23a is formed from above the terminal 20 to below, the inserting direction is perpendicular to the axial direction of the terminal 20.

The lid 30 is composed of a ceiling plate 31 formed to be larger than the opening 14 portion of the connector case 10 and side sides 32 extending downward from the left and right end sides of the ceiling plate 31. A clamp 31 a is formed on the upper surface of the ceiling plate 31, and a pressing protrusion 31 b is formed on the lower surface of the ceiling plate 31 so as to project toward the inside of each cylindrical portion 13. The clamp 31a is composed of a trunk portion 31a1 that vertically projects from the ceiling plate 31, and wing portions 31a2 and 31a2 that obliquely project from the tip of the trunk portion 31a1 toward the upper surface of the ceiling plate 31. On the other hand, a rectangular fixing hole 51 shown in FIG. 4 is formed in the vehicle body 50 in which the press-connecting connector 40 is arranged. Here, the length of the fixing hole 51 in the lateral direction corresponds to the thickness of the clamp 31a in the front-rear direction, and the length of the fixing hole 51 in the longitudinal direction is the length in the width direction of the clamp 31a including the wing portion 31a2. It's shorter than that.

On the other hand, an engaging protrusion 32a protruding inward is formed at the lower end of the side edge 32. Correspondingly, the engaging protrusion 32a can be engaged under the side surface of the connector case 10. The concave portion 15 is formed. Next, the operation of this embodiment having the above configuration will be described. As shown in FIG. 5, the terminal 20 is inserted into the tubular portion 13. It should be noted that the method of engaging and holding the terminal 20 in the cylindrical portion 13 may be a general engaging method. When the terminal 20 is inserted into the cylindrical portion 13 at a predetermined position, the pressure contact portion 22 is located at the position of the opening 14 in the connector case 10, and the pressure contact metal fitting 23 faces the opening 14. When the electric wire W to be pressed is placed along the upper surface of the connector case 10 and the electric wire in the opening 14 is pushed into the cylindrical portion 13, the electric wire W is inserted into the press-fitting slot 23 a of the press-fitting metal fitting 23. This state is shown in FIGS. 6 and 7. When the electric wire W is inserted into the press contact slot 23a, the end of the metal fitting is cut into the cover, so that the electric wire W comes into contact with the electric wire portion to establish electrical conduction. In this way, as many conductors as necessary are pressure-welded.

Next, when the lid 30 is pushed toward the connector case 10, the engagement protrusion 32a of the side edge 32 comes into contact with the side surface of the connector case 10 and the side edge 32 is expanded. When the push-in projection 31b is further pushed in as it is, the push-down projection 31b comes into contact with the upper surface of the electric wire W inserted into the tubular portion 13 and further pushes it down. When the push-down protrusion 31b pushes the wire W to a position where it is pushed down to a predetermined position in the press-contact slot 23a, the engaging protrusion 32a of the side edge 32 enters into the concave portion 15 formed on the side surface of the connector case 10 and engages with it. FIG. 7 shows a state in which the pressure contact connector 40 is connected to the middle of the conductor W in this manner. When this harness is attached to the vehicle body 50, the clamp 31a of the pressure contact connector is pushed into the fixing hole 51 formed in the vehicle body 50. Since the width of the fixing hole 51 is shorter than the width of the wings 31a2, 31a2 spreading on both sides of the trunk 31a1, the wings 31a2, 31a2 come into contact with the edge of the fixing hole 51, but when pushed in with force. The wing portions 31a2 and 31a2 can be inserted into the fixing hole 51 by bending toward the trunk portion 31a1. When passing through the fixing hole 51, the wings 31a2, 31a2 open, and when attempting to pull out, the back side of the vehicle body 50 tries to open around the fixing hole 51 to prevent the blades from coming off.

At this time, as shown in FIG. 9, the respective members are arranged in the order of the vehicle body 50, the ceiling plate 31, the electric wire W, and the connector case 10 from the vehicle body 50 side. That is, the pair of connectors is inserted into the hood portion 11 of the connector case 10, but since the electric wire W is disposed in the back of the hood portion 11, there is nothing on the front side of the hood portion 11, It is easy to fit each other. FIG. 10 shows another embodiment of the present invention. In the press-connecting connector 40 shown in the figure, the connector case 10 and the lid 30 are not formed as separate parts, but are connected integrally with a thin strip plate 33 instead of the one side 32 and are integrally molded. When assembling, the electric wire W is assembled up to the pressure contact in the same manner as described above, and thereafter, while bending the strip 33, the remaining side 32 is wound around the connector case 10 side and engaged.

11 and 12 show another embodiment of the present invention. In the figure, the connector case 61 has a hood portion 62 at the lower portion in the figure and a terminal holding portion 63 at the upper portion in the figure. A pressure contact portion 64a of the terminal 64 is arranged on the upper surface side of the terminal holding portion 63, and a pressure contact slot 64a1 is formed in each pressure contact portion 64a. Further, an engaging projection 65 is formed on the side surface of the terminal holding portion 63. On the other hand, the lid 66 includes a base wall 67 facing the surface where the pressure contact portion 64a is provided, engagement walls 68a and 68b vertically extending from both ends of the base wall 67 in the longitudinal direction, and a base wall 67. And a restriction wall 69 extending vertically from the long side of the above and connecting both engaging walls 68a and 68b. Here, engagement holes 68a1 and 68b1 into which the engagement projections 65 can be fitted are formed in both engagement walls 68a and 68b, and a fixing clamp 69a is formed in the restriction wall 69.

In such a configuration, the electric wire W is press-fitted into the press-contact slot 64a1 of each press-contact portion 64a to cover the lid 66. The regulation wall 69 of the lid 66 contacts the electric wire W and bends along the hood portion 62. The completed harness is as shown in FIG. 12, and when the harness 69 is attached to the vehicle body with the clamp 69a, the electric wire W is sandwiched between the hood portion 62 and the vehicle body. Therefore, it becomes easy to insert the paired connector into the hood portion 62. Regarding the lid 66, a wall portion similar to the regulation wall 69 may be formed on the remaining long side of the base wall 67 to cover the terminal holding portion 63 of the connector case 61. At this time, the clamp 69a may be attached to any wall of the lid 66.
