Description

The present invention relates to a connector, particularly a connector in which a terminal holder is insert-molded.

Conventionally, in a connector in which the terminal holder is insert-molded into the connector body, the positioning hole for determining the position of the terminal holder is exposed to the outside of the connector at the time of insert molding, and the terminal holder and the connector body are connected to each other. There was a risk of water entering from the boundary. Therefore, an invention that does not expose the boundary portion to the outside is disclosed (see, for example, Patent Document 1).

Japanese Patent No. 4849323 (pages 4-5, FIG. 4)

In the invention disclosed in Patent Document 1, in insert molding, a slide core protruding from the tip of a slide type for forming a hood opening which is a part of a connector is provided, and a fitting hole is provided in the terminal holder. The terminal holder is positioned by fitting the slide core into the fitting hole. Therefore, although the boundary between the terminal holder and the connector body is not exposed to the outside of the connector, the surface provided with the fitting hole of the terminal holder forms the bottom surface of the hood opening, and the terminal holder and the connector body are formed. The boundary with the hood was exposed at the opening of the hood.
Then, when water infiltrates into the hood opening, there is a problem that a leak may occur between the terminals attached to the terminal holder, and there is a problem that water may infiltrate into the boundary portion.
In addition, since multiple terminals are attached to the terminal holder in a row and fitting holes are provided at positions vertically separated from each other in the terminal row, positioning accuracy is poor and terminal alignment may be poor. There was a problem.
Further, when the terminal holder is tilted because the tip of the terminal attached to the terminal holder penetrates (slides) into the slide type before the slide core is fitted into the fitting hole and positioned. There is a problem that the terminal and the slide type may interfere with each other and damage the terminal.

The present invention is to solve the above-mentioned problems, and to provide a connector in which the risk of leakage between terminals and water intrusion into the boundary portion is eliminated, and misalignment and damage of terminals are prevented.

The connector according to the present invention is a connector in which a terminal holder to which a plurality of first terminals and a plurality of second terminals are assembled is insert-molded into a connector body.
The terminal holder has a flat plate-shaped holder base having a holder first surface and a holder second surface facing each other, and a holder hill formed on one side of the holder second surface.
In the first terminal, an intermediate range is arranged on the first surface of the holder, and a part of one end range penetrates the holder first terminal hole provided on the holder hill, and one tip portion thereof is formed. The second terminal protrudes from the surface of the holder hill, and an intermediate range is arranged on the holder second surface, and a part of one end range penetrates into the holder second terminal groove provided on the holder hill. However, one of the tips protrudes from the surface of the holder hill, and the holder first terminal hole and the holder second terminal groove are arranged in a rectangular shape, and the holder first terminal hole and the holder second terminal groove are arranged in a grid pattern. Holder positioning holes with a substantially rectangular cross section are provided on the outside in the width direction, respectively.
The connector body has a connector hood that surrounds the holder pedestal, one tip of the first terminal, and one tip of the second terminal, and a part of the connector hood is on the surface of the holder hill. A hood opening bottom plate is installed, and the hood opening bottom plate has a hood positioning hole communicating with the holder positioning hole, and one tip of the first terminal and one tip of the second terminal, respectively. A hood first terminal hole and a hood second terminal hole are formed to penetrate the hood, and the range of one tip of the first terminal protruding from the hood first terminal hole and the tip of one of the second terminals are described. The range protruding from the second terminal hole of the hood is characterized in that it protrudes into the hood opening which is a part of the connector hood.
Further, the length (A) of the holder positioning hole is larger (A> B) than the distance (B) between the first terminal and the second terminal on the holder hill.
Further, the depth (D) of the holder positioning hole from the surface of the holder hill is larger than the protrusion amount (H) of the first terminal and the second terminal from the surface of the bottom plate of the hood opening ( It is characterized by D> H).
Further, the holder positioning recess is provided at the center position in the longitudinal direction of the bottom surface of the holder positioning hole.
Further, a substantially trapezoidal trapezoidal or substantially conical trapezoidal hood opening bottom plate first convex portion and a hood opening bottom plate second convex portion are formed on the surface of the hood opening bottom plate, and the first terminal and the second terminal are formed. Each of the terminals is characterized by penetrating the first convex portion of the bottom plate of the hood opening and the second convex portion of the bottom plate of the hood opening.

The connector according to the present invention is the outer side of the holder first terminal hole and the holder second terminal groove arranged in a grid direction in the width direction, that is, the holder first terminal hole and the holder second terminal arranged in a row, respectively. Since the holder positioning hole is provided at the extension position in the row direction, the accuracy of the position regulation of the terminal holder is high, and the accuracy of the alignment of the first terminal hole and the second terminal is improved.
In addition, since the holder pedestal is surrounded by the connector hood and the holder positioning hole formed in the holder pedestal communicates with the hood positioning hole formed in the bottom plate of the hood opening, the terminal holder (holder pedestal) and the connector body (hood). Since the interface with the bottom plate of the opening is exposed only to the hole where the holder positioning hole and the hood positioning hole are combined (same as the "water storage hole" described later), the possibility of water entering the boundary portion is reduced.
Further, since the length (A) of the holder positioning hole is larger than the distance (B) between the first terminal and the second terminal on the holder hill (A> B), the holder positioning hole and the hood positioning hole are combined. The holes (same as the "water storage holes" described later) exert a water storage function, making it difficult for polar leaks to occur.
Further, since the depth (D) of the holder positioning hole is larger than the protrusion amount (H) of the first terminal and the second terminal (D> H), the holder positioning hole provided in the slide mold at the time of insert molding is formed. After the tip of the invading part (same as the "punch positioning part" described later) invades the holder positioning hole, the first terminal and the second terminal enter the part where the first terminal and the second terminal provided in the slide type invade. Since the tips of the terminals intrude into each other, the "pickability" of the slide type is improved, and the deformation and damage of the first terminal and the second terminal are prevented.

That is, the total of the holder positioning hole depth D and the hood opening bottom plate thickness T (hereinafter referred to as "punch positioning portion length L1"; L1 = D + T) is the protrusion amount H and the hood opening bottom plate thickness T. It is larger than the total (hereinafter referred to as "holder height protrusion amount L2". L2 = H + T) (L1> L2).

(Insert molding type)
7 to 9 schematically show insert molding of the connector according to the first embodiment, and FIG. 7 is a perspective view showing a part (slide punch) of the insert molding mold, FIGS. 8 and 9. 9 is a side view showing a part of the molding process as a cross section.
In FIGS. 7 to 9, the slide punch (same as the slide mold) 400 constituting the insert molding die has a punch body 460 for forming the hood opening 260 and an end face of the punch body for forming the surface 250a of the hood opening bottom plate 250. It has 460a. Then, a punch first terminal hole 461 and a punch second terminal hole 462 into which the tip portions of the first terminal 1 and the second terminal 2 penetrate are opened in the punch main body end surface 460a, and the punch first terminal hole 461 and the punch are opened.

At this time, the distance from the tip surface 450a of the punch positioning portion 450 to the punch body end surface 460a (same as the punch positioning portion length L1) is such that the holder pedestal protrudes from the surface 140a of the holder pedestal 140 of the first terminal 1 and the second terminal. It is larger than the quantity L2 (L1> L2).
Further, the side surface of the punch positioning portion 450 is provided with a punched tapered surface for facilitating die cutting during insert molding, while the inner wall of the holder positioning hole 150 is also formed on the tapered surface having the same inclination. When the convex portion 451 of the punch positioning portion is fitted into the holder positioning recess 151, the side surface of the punch positioning portion 450 comes into close contact with the inner wall of the holder positioning hole 150.

Therefore, the slide punch 400 is lowered while the terminal holder 100 to which the first terminal 1 and the second terminal 2 are assembled is held by a die or a fixed punch (not shown), and the tip surface 450a of the punch positioning portion 450a. When the player reaches the surface 140a of the holder hill 140, the tips of the first terminal 1 and the second terminal 2 have not yet reached the end surface 460a of the punch body (see FIG. 9).
When the tip surface 450a reaches the surface 140a, the holder hill protrudes until the first terminal 1 reaches the punch first recess 463 and the tip of the second terminal 2 reaches the punch second recess 464. The amount L2 may be extended (in the present invention, the punch first recess 463 and the punch second recess 464 are made uniform on the tip surface 450a).

(Positioning of terminal holder)
Then, when the slide punch 400 further descends, the punch positioning portion 450 invades the holder positioning hole 150, and eventually the punch positioning portion convex portion 451 fits into the holder positioning recess 151, and the tip surface 450a abuts on the bottom surface 150a. The side surface of the punch positioning portion 450, which is a tapered surface, and the inner wall of the holder positioning hole 150 are in close contact with each other.
At this time, a gap corresponding to the hood opening bottom plate thickness T of the hood opening bottom plate 250 is formed between the punch body end surface 460a of the slide punch 400 and the surface 140a of the holder hill 140 (to be exact, the connector). A gap obtained by adjusting the amount of shrinkage or expansion of the resin forming the main body 200). That is, the end surface 460a of the punch body forms the surface 250a of the hood opening bottom plate 250, the surface 140a of the holder hill 140 forms the back surface 250b of the hood opening bottom plate 250, and the gap forms the hood opening bottom plate 250. become. Therefore, the punch positioning portion length L1 is the sum of the holder positioning hole depth D and the hood opening bottom plate thickness T (L1 = D + T, see FIG. 3).

(Action effect)
Since the connector 300 is a secondary molded body manufactured by the insert molding, it has the following effects.
(A) Since the holder positioning holes 150 are provided near both sides of the holder first terminal hole 141 and the holder second terminal groove 142 arranged in a grid shape in the width direction (Y direction), the terminal holder 100 The accuracy of position regulation is high, and the accuracy of alignment of the first terminal 1 and the second terminal 2 is improved. That is, even if the terminal holder 100 is displaced around the holder positioning hole 150 at the fulcrum (rotated in the XX plane about the Y axis), the tip of the first terminal 1 and the tip of the second terminal 2 are used. Is close to the fulcrum (center of rotation), so the amount of deviation is small.
(B) Further, the convex portion 451 of the punch positioning portion fits into the holder positioning recess 151 (hereinafter referred to as “first-stage fitting”), and the side surface of the punch positioning portion 450 and the holder positioning hole, both of which are tapered surfaces. Since it is in close contact with the inner wall of 150 (hereinafter referred to as "second stage close contact"), the accuracy of position regulation of the terminal holder 100 is further improved, and the alignment accuracy of the first terminal 1 and the second terminal 2 is further improved. That is, the Y direction, which is difficult to incline in the first-stage fitting, is restricted, and the X-direction, in which the amount of inclination is large, is restricted in the second-stage adhesion.
(C) Further, since the punch positioning portion length L1 (L1 = D + T) is larger than the holder height protrusion amount L2 (L2 = H + T) of the first terminal 1 and the second terminal (L1> L2), the insert is inserted. At the time of molding, after the punch positioning portion 450 has entered the holder positioning hole 150, the first terminal 1 has entered the punch first terminal hole 461 and the second terminal has entered the punch second terminal hole 462. That is, since the intrusion starts after the first terminal 1 and the second terminal 2 are aligned, the "pickability" of the first terminal 1 and the second terminal 2 is improved by the slide punch 400, and deformation and damage are prevented. To.

(D) Further, even when water enters the hood opening 260, the water storage hole 350 in which the holder positioning hole 150 and the hood positioning hole 255 are integrated exhibits a water storage function, and is deep and has a large volume. Therefore, it becomes possible to store the infiltrated water. Therefore, the possibility that the infiltrated water overflows to the surface 250a of the hood opening bottom plate 250 is reduced, and interpolar leakage is less likely to occur.
(E) Further, almost the entire surface of the terminal holder 100 is surrounded by the connector main body 200, and only the boundary surface exposed portion 355 is exposed in the water storage hole 350. That is, the boundary surface exposed portion 355 is limited to an extremely narrow range, and the distance from the boundary surface exposed portion 355 to the bottom surface 150a of the holder positioning hole 150 is equal to the holder positioning hole depth D, and the holder positioning hole 150 is deep. Due to the large volume, even if water that has entered the hood opening 260 collects in the holder positioning hole 150, it is difficult for the water to reach the boundary surface exposed portion 355. Therefore, the possibility that the infiltrated water will infiltrate from the boundary surface exposed portion 355 is reduced, and the leakage between the poles is less likely to occur.
(F) Further, since the hood bottom surface first convex portion 253 and the hood bottom surface second convex portion 254 are formed on the surface 250a of the hood opening bottom plate 250, water is temporarily stored in the hood opening 260. Even if the water accumulated in the hole 350 overflows and covers the surface 250a, the interpolar leak does not occur unless it reaches the tips of the first convex portion 253 on the bottom surface of the hood and the second convex portion 254 on the bottom surface of the hood.
