As shown in FIGS. 4 and 5, the contact assembly 20 is composed of a contact accommodating portion 30 and a contact subassembly 31. The contact subassembly 31 is composed of a plurality of plug contacts 32 (contacts) and a contact holding portion 33. As shown in FIG. 4, the contact accommodating portion 30 and the contact holding portion 33 form a housing H that holds a plurality of plug contacts 32.

As shown in FIG. 5, the plurality of plug contacts 32 are arranged so as to form two rows separated in the height direction, similarly to the plurality of receptacle contacts 10 of the receptacle 5 shown in FIG. The plurality of plug contacts 32 included in the upper row of the two rows are arranged at predetermined intervals in the pitch direction. Similarly, the plurality of plug contacts 32 included in the lower row of the two rows are arranged at predetermined intervals in the pitch direction. The predetermined spacing is, for example, 1.27 mm, but is not limited to this.

The plurality of plug contacts 32 have the same shape. Of the plurality of plug contacts 32, the four plug contacts 32 arranged above and the four plug contacts 32 arranged below are arranged so as to be upside down.

It is supported by the holding portion 33.

As shown in FIGS. 7 and 8, the contact portion 40 has a first extension portion 50 and a second extension portion 51.

The first extension portion 50 extends from the fixed portion 41 in the fitting direction. The first extension portion 50 extends from the fixed portion 41 in a direction away from the fixed portion 41. The first extension portion 50 has a tip 50A in the fitting direction. The plate thickness direction of the first extension portion 50 is orthogonal to the pitch direction.

The second extension portion 51 extends in the removal direction from the tip 50A of the first extension portion 50. The second extension portion 51 extends from the tip 50A of the first extension portion 50 so as to approach the fixed portion 41.

The first extension portion 50 and the second extension portion 51 face each other in the height direction. Therefore, as shown in FIG. 7, the contact portion 40 is formed in a U shape that opens toward the fixed portion 41 when viewed in the pitch direction.

In FIG. 7, the boundary line Q between the first extension portion 50 and the second extension portion 51 is shown by a broken line. As shown in FIG. 7, the first extension portion 50 and the second extension portion 51 are smoothly connected while being curved so as to be convex in the fitting direction in the vicinity of the boundary line Q.

The first extension portion 50 has a linear extension portion 52 and a curved extension portion 53. The linear extension portion 52 and the curved extension portion 53 are connected in the order of description in the fitting direction.

The linear extension portion 52 extends from the fixed portion 41 in the fitting direction. The linear extension portion 52 is a portion that extends substantially linearly in the no-load state of the plug contact 32. The linear extension portion 52 is slightly inclined downward toward the fitting direction in the no-load state of the plug contact 32.

As shown in FIGS. 7 and 8, the second extension portion 51 has a narrow portion 55, a tapered portion 56, and a wide portion 57. The narrow portion 55, the tapered portion 56, and the wide portion 57 are connected in the order described in the extraction direction.

The narrow portion 55 is a portion that extends from the tip 50A of the first extension portion 50 while being curved in the extraction direction.

The tapered portion 56 is a portion that extends from the narrow portion 55 in the removal direction and gradually widens.

The wide portion 57 is a portion extending from the tapered portion 56 in the removal direction. As shown in FIG. 8, the wide portion 57 is wider than the narrow portion 55. That is, the dimension 57W of the wide portion 57 in the pitch direction is larger than the dimension 55W of the narrow portion 55 in the pitch direction. Returning to FIG. 7, the wide portion 57 has an inward direction 57A facing the first extension portion 50. The inward direction 57A is a surface facing downward.

The second extension portion 51 is located above the first extension portion 50. That is, the second extension portion 51 is arranged on the opposite side of the other plug contact 32 that faces the plug contact 32 to which the second extension portion 51 belongs in the height direction with the first extension portion 50 interposed therebetween.

As shown in FIG. 9, the contact accommodating portion 30 is made of an insulating resin such as LCP (Liquid Crystal Polymer), and is formed in a square tube shape extending in the insertion / extraction direction. That is, the contact accommodating portion 30 is formed with a receptacle insertion frontage 60 as a mating connector accommodating space for receiving the receptacle 5. The receptacle insertion frontage 60 is formed so as to penetrate the contact accommodating portion 30 in the insertion / removal direction.

The contact accommodating portion 30 has two height direction division screens 61 that partition the receptacle insertion frontage 60 in the height direction. A plurality of contact receiving grooves 62 are formed on each height direction screen 61. Each contact receiving groove 62 is a groove that receives each plug contact 32. Each contact receiving groove 62 is formed so as to open toward the receptacle insertion frontage 60 and in the insertion / removal direction. Therefore, the contact accommodating portion 30 partitions each contact receiving groove 62 in the pitch direction, and has a plurality of contact facing walls 63 facing each plug contact 32 inserted in each contact receiving groove 62 on both sides thereof in the pitch direction. Has (opposing wall). Specifically, the two contact facing walls 63 adjacent to each other in the pitch direction partition one contact receiving groove 62 in the pitch direction and face the plug contact 32 inserted in the contact receiving groove 62 in the pitch direction. .. That is, the contact receiving grooves 62 and the contact facing walls 63 are alternately formed in the pitch direction. In other words, one contact receiving groove 62 is formed between the two contact facing walls 63, and one contact facing wall 63 is formed between the two contact receiving grooves 62.

Each contact facing wall 63 has two contact facing surfaces 64. Each contact facing surface 64 is a surface orthogonal to the pitch direction. A preload recess 65 extending in the insertion / removal direction is formed on each contact facing surface 64. The preload recess 65 is formed so as to open in the removal direction.

Of the plurality of contact facing walls 63, the plurality of contact facing walls 63 arranged above the receptacle insertion frontage 60 and the plurality of contact facing walls 63 arranged below are configured upside down. Therefore, the contact facing wall 63, which is one of the plurality of contact facing walls 63 arranged above, will be described in detail below.

As shown in FIG. 10, the contact facing wall 63 has a preload surface 70 and a guide surface 71 for partitioning the preload recess 65. Both the preload surface 70 and the guide surface 71 are flat surfaces facing upward, and are formed in a row in the drawing direction in the order described.

The preload surface 70 is a plane orthogonal to the height direction.

The guide surface 71 is a flat surface that slightly inclines downward toward the removal direction.

In the present embodiment, the preload surface 70 and the guide surface 71 are connected so as to form an angle, but instead of this, a curved surface may be interposed and smoothly connected.

Next, a method of assembling the contact assembly 20 will be described with reference to FIGS. 11 and 12.

First, as shown in FIG. 11, the contact subassembly 31 and the contact accommodating portion 30 are opposed to each other in the insertion / removal direction. At this time, the contact subassembly 31 and the contact accommodating portion 30 are arranged so as to be arranged in the order described in the fitting direction.

Next, from the state of FIG. 11, the contact subassembly 31 is moved in the fitting direction relative to the contact accommodating portion 30. Then, as shown by the alternate long and short dash line, the wide portion 57 of the second extension portion 51 of the contact portion 40 of each plug contact 32 is captured by the corresponding preload recess 65. Specifically, the inner surface 57A of the wide portion 57 of each plug contact 32 comes into contact with the corresponding guide surface 71. More specifically, of the wide portions 57 of each plug contact 32 shown in FIG. 8, the guide surface corresponding to the inward 57A of the two lateral protrusions 58 projecting outward in the pitch direction from the narrow portion 55. Contact each of 71.

When the contact subassembly 31 is further moved in the fitting direction from this state, the wide portion 57 of each plug contact 32 slides with respect to the corresponding guide surface 71 and moves along the inclination of the guide surface 71. At this time, since the guide surface 71 is inclined upward toward the fitting direction, the wide portion 57 is gradually displaced upward with elastic deformation of the first extension portion 50.

Eventually, as shown in FIG. 12, the wide portion 57 reaches the preload surface 70 and comes into contact with the preload surface 70. On the other hand, when the contact holding portion 33 comes into contact with the plurality of contact facing walls 63 in the insertion / removal direction, further movement of the contact subassembly 31 in the fitting direction is prohibited.

In the state of FIG. 12, the wide portion 57 is in a state of being displaced upward mainly with elastic deformation of the first extension portion 50. That is, in the state of FIG. 12, the contact portion 40 of the plug contact 32 is elastically deformed in the direction away from the receptacle insertion frontage 60. The state in which the contact is held in the elastically deformed state is called the preload state. Then, by setting the plug contact 32 in the preload state, the position and posture of each plug contact 32 can be set to a desired position and posture before fitting the plug 4 and the receptacle 5. Therefore, the contact pressure when each plug contact 32 comes into contact with each receptacle contact 10 is ensured as designed without variation, and high connection reliability between the plug 4 and the receptacle 5 is realized.

In particular, when the signal line P1 corresponding to the solder connection surface 42A of the electric wire connection portion 42 of each plug contact 32 shown in FIG. 6 is solder-connected, the contact holding portion 33 is slightly melted by heating each plug contact 32. If each plug contact 32 is not in the preloaded state and is held by the contact holding portion 33 by releasing one end like a cantilever, for example, the position and orientation of each plug contact 32 will change unknowingly. Can be considered. Therefore, setting each plug contact 32 in the preloaded state is particularly advantageous when the signal line P1 is solder-connected to each plug contact 32.

Next, a method of manufacturing the plug 4 will be described with reference to FIGS. 13 to 15.

First, as shown in FIG. 13, the end treatment of the electric wire 2 is performed. Specifically, the sheath P2 is excised for a predetermined length, a braid (not shown) is folded back, and a copper foil P3 is wound around the folded braid. For each signal line P1, the conductor P5 is exposed for a predetermined length by cutting off the insulating coating P4.

Next, as shown in FIG. 14, the conductors P5 of the plurality of signal lines P1 are aligned using the locator 23, and the plurality of signal lines P1 are fixed between the locator 23 and the copper foil P3 by the resin mold P6.

Then, as shown in FIG. 15, the conductor P5 of each signal line P1 is solder-connected to the solder connection surface 42A of the wire connection portion 42 of the corresponding plug contact 32 of the contact assembly 20 by using an automatic solder connection device. In FIG. 15, the conductor P5 of each signal line P1 is drawn slightly floating from the corresponding solder connection surface 42A, but the conductor P5 of each signal line P1 is automatically soldered to the corresponding solder connection surface 42A. It is pressed by the wire connection device at the time of solder connection.

Next, as shown in FIG. 3, the main shield 21, the sub-shield 22, and the boot assembly 24 are assembled to the contact assembly 20 and the electric wire 2. Then, as shown in FIG. 2, the two hoods 16 and the release lever 17 are assembled to the plug body 15.

Although the preferred embodiment of the present invention has been described above, the above-described embodiment has the following features.

As shown in FIG. 4, the plug 4 (connector) includes a plug contact 32 (contact) and a housing H (housing) that holds the plug contact 32. The housing H holds the plug contact 32 in an elastically deformed state. As shown in FIG. 12, the plug contact 32 includes a fixed portion 41 fixed to the contact holding portion 33 (housing), a first extension portion 50 extending from the fixed portion 41 so as to be separated from the fixed portion 41, and a first extension portion 50. It has a second extension portion 51 extending from the first extension portion 50 so as to approach the fixed portion 41. The plug contact 32 is elastically deformed when the second extension portion 51 comes into contact with the preload surface 70 of the contact accommodating portion 30 (housing). According to the above configuration, downsizing of the plug 4 held in the housing H in a state where the plug contact 32 is elastically deformed is realized.

In particular, as compared with the configuration of Patent Document 1, since the second extension portion 51 extending toward the fixed portion 41 is in contact with the housing H and is in the preloaded state, downsizing in the insertion / removal direction of the plug 4 is realized. Has been done. Further, since the length of the contact portion 40 in the insertion / removal direction is also suppressed, the amount of bending when the contact portion 40 is bent upward is also suppressed, and thus downsizing in the height direction of the plug 4 is also realized at the same time. ..

Subsequently, as shown in FIG. 12, the second extension 51 has an inward direction 57A facing the first extension 50. The plug contact 32 is elastically deformed when the inner surface 57A of the second extension portion 51 comes into contact with the housing H. According to the above configuration, a configuration in which the plug contact 32 is elastically deformed upward in the direction in which the first extension portion 50 to the second extension portion 51 is viewed is realized.

As shown in FIG. 8, the second extension portion 51 has a wide portion 57. The plug contact 32 has a narrow portion 55 that is narrower than the wide portion 57 between the wide portion 57 and the fixed portion 41. Then, as shown in FIG. 12, the plug contact 32 is elastically deformed when the inner surface 57A of the wide portion 57 comes into contact with the housing H. According to the above configuration, the plug contact 32 can be assembled to the contact accommodating portion 30 in the fitting direction in which the first extension portion 50 extends from the fixed portion 41.

In the above embodiment, the second extension portion 51 has the narrow portion 55, but instead, the first extension portion 50 may be configured to have the narrow portion 55.

As shown in FIGS. 9, 10 and 11, the housing H has a contact facing wall 63 facing the plug contact 32 in the pitch direction as the width direction of the plug contact 32. The contact facing wall 63 has a guide surface 71 (contact surface) capable of contacting the inner surface 57A of the wide portion 57. As shown in FIG. 12, when viewed along the pitch direction, the guide surface 71 extends so as to incline toward the first extension portion 50 as it approaches the fixed portion 41. According to the above configuration, when the plug contact 32 is assembled to the contact accommodating portion 30 in the fitting direction in which the first extension portion 50 extends from the fixed portion 41, the wide portion 57 moves along the guide surface 71. , The plug contact 32 is automatically elastically deformed upward in the direction from the first extension portion 50 to the second extension portion 51. Therefore, it is not necessary to elastically deform the plug contact 32 before assembling it to the contact accommodating portion 30, and the assembling workability is improved.

Instead of using the guide surface 71 to preload the plug contact 32, the two plug contacts 32 are pushed by inserting a jig between the two plug contacts 32 facing each other in the height direction. A plurality of plug contacts 32 may be assembled to the contact accommodating portion 30 in the unfolded state.

The housing H includes a contact holding portion 33 that holds the fixed portion 41 of the plug contact 32 by insert molding, and a contact accommodating portion 30 that is configured to be connectable to the contact holding portion 33 and has a contact facing wall 63. Including.

The contact accommodating portion 30 has a receptacle insertion frontage 60 (another connector accommodating space) for receiving a receptacle 5 (another connector). The second extension portion 51 is arranged on the side opposite to the receptacle insertion frontage 60 with the first extension portion 50 interposed therebetween.

As shown in FIG. 1, the wire harness E includes a plug 4 and an electric wire 2.
