Definitions
- the present disclosure relates to terminals and connectors.
- a terminal that does not easily damage the mat seal during insertion is known (Japanese Patent Laid-Open No. 2016-001579).
- a lance engaging portion and a locking portion having inclined portions are formed by bending, so that the broken surface of the metal plate does not come into contact with the mat seal. Further, when the terminal is pulled out from the mat seal and separated, the inclined portion of the locking portion comes into contact with the mat seal, so damage to the mat seal can be suppressed.
- the convex lance engaging portion and locking portion are formed by intricately bending the metal plate. For this reason, there is a risk that the number of man-hours required for molding will increase, or that the cost of raw materials and processing will increase.
- the present disclosure has been completed based on the circumstances as described above, and aims to provide a technique of suppressing damage to the mat seal during detachment with a simple structure.
- the present disclosure is a terminal that is inserted from the rear to the front into a seal hole of a mat seal provided in a housing and that is removed from the front to the rear, the terminal including a substantially box-shaped first box portion, the first box portion having a first bottom wall, a pair of first side walls rising from both ends of the first bottom wall, a first ceiling wall facing the first bottom wall, and a locking wall positioned at a rear end that is a tip in a detachment direction, and the first ceiling wall and the locking wall It is connected via a connecting portion curved from the detachment direction to the direction of the first bottom wall.
- FIG. 1 is an exploded perspective view of a female connector including terminals according to Embodiment 1.
- FIG. FIG. 2 is a side cross-sectional view showing a state in which the terminals are held in their normal positions.
- FIG. 3 is a perspective view of the terminal viewed obliquely from above and behind. 4 is a partially enlarged view of FIG. 3.
- FIG. 5 is a partially enlarged view of FIG. 2.
- FIG. FIG. 6 is a side cross-sectional view showing the terminal in contact with the seal hole during the detachment process.
- FIG. 7 is a perspective view showing a conventionally shaped terminal.
- FIG. 8 is a side cross-sectional view showing the terminal in contact with the seal hole in the process of detaching the conventionally-shaped terminal.
- the present disclosure is a terminal that is inserted from the rear to the front into a seal hole of a mat seal provided in a housing and that is removed from the front to the rear, and includes a substantially box-shaped first box portion, the first box portion having a first bottom wall, a pair of first side walls rising from both ends of the first bottom wall, a first ceiling wall facing the first bottom wall, and a locking wall positioned at a rear end that is a tip in a detachment direction, wherein the first ceiling wall and the locking wall are: It is connected via a connecting portion curved in the direction of the first bottom wall from the detachment direction.
- the connecting portion curved from the detachment direction toward the first bottom wall contacts the seal hole before the fractured surface. Since the seal hole is expanded by the connecting portion, contact with, for example, a fractured surface formed at the rear end of the first box portion can be avoided, and damage to the mat seal can be suppressed.
- the load When a load is applied to the terminal in the detachment direction, the load can be received by the plate surface of the locking wall. As a result, the load is distributed over the entire plate surface, and deformation of the terminal can be suppressed.
- At least one of the first side walls has an extension portion extending toward the rear, and the extension end of the extension portion overlaps the plate surface of the locking wall when viewed from the direction perpendicular to the detachment direction.
- the extension end can also receive the load in the detachment direction. As a result, the load is further distributed, and deformation of the terminal can be suppressed.
- the terminal includes a substantially box-shaped second box portion spaced forward from the first box portion.
- the second box portion has a second bottom wall, a pair of second side walls rising from both ends of the second bottom wall, and a second ceiling wall facing the second bottom wall.
- the second box portion passes through the seal hole expanded by the first box portion. Since the height of the second box portion is smaller than the height of the first box portion, the second box portion is less likely to get caught in the seal hole, and the terminal can be easily removed from the housing. Since the load on the terminal is reduced when it is detached, deformation of the second box portion can be suppressed.

- the first side walls 58A and 58B are collectively referred to as the first side wall 58.
- the first bottom wall 57 is a part of the lower wall of the main body 51 and extends in the front-rear direction and the left-right direction (width direction).
- the first bottom wall 57 is connected to the wire barrel portion 52 via the connecting portion 62 .
- the first side wall 58 rises from both left and right ends of the first bottom wall 57 .

- the connecting portion 60 is connected to the rear end of the first ceiling wall 59 at substantially the center.
- the lateral width of the connecting portion 60 is smaller than the width of the first ceiling wall 59 .
- a rectangular plate-like locking wall 61 that is elongated in the left-right direction is connected to the tip of the connection portion 60 .

- the locking wall 61 is arranged to block the upper half of the cylindrical body surrounded by the first bottom wall 57, the first side wall 58, and the first ceiling wall 59 from the rear.
- the connecting portion 60 when the terminal 50 is removed (pulled out) from the housing 10, the connecting portion 60 first comes into contact with the inner peripheral surface of the seal hole 41, as shown in FIG. Since the connecting portion 60 is smoothly curved downward from the rear, the terminal 50 is less likely to get caught in the seal hole 41 and damage the inner peripheral surface of the seal hole 41 .
- the seal hole 41 is expanded by the connecting portion 60 . As a result, contact with, for example, a fractured surface formed at the rear end corner of the first box portion 54 can be avoided during detachment, and damage to the seal hole 41 by the terminal 50 can be suppressed.
- the terminal 50 is prevented from coming off by the restricting portion 34 of the retainer 30 .
- the plate surface of the locking wall 61 abuts against the front surface of the restricting portion 34 to restrict displacement of the terminal 50 .
- one first side wall 58 (first side wall 58A in this embodiment) has an extension 64 extending rearward on the rear end side.
- the extending portion 64 is positioned below the boundary between the first ceiling wall 59 and the first side wall 58A and above the side portion 63 .
- a rear edge (an example of an extending end) 64A of the extending portion 64 extends vertically.
- the length of the extending portion 64 in the front-rear direction is set such that the rear edge 64A overlaps the plate surface of the locking wall 61 when viewed in the left-right direction.
- a rear edge 64A of the extending portion 64 overlaps the plate surface of the locking wall 61 when viewed from the left-right direction. Therefore, when an external force is applied to the terminal 50 in the separating direction, the plate surface of the locking wall 61 and the rear edge 64A come into contact with the front surface of the restricting portion 34 . Thereby, the load is further dispersed, and deformation of the terminals 50 can be suppressed.
- the second box portion 55 is arranged on the front side with a gap from the first box portion 54, and an intermediate portion 56 is arranged between the first box portion 54 and the second box portion 55.
- the second box portion 55 has a second bottom wall 70 located on the lower side, a pair of second side walls 71A and 71B, and a second ceiling wall 72 located on the upper side.
- the second side walls 71A and 71B are collectively referred to as the second side wall 71.
- the 2nd box part 55 of this embodiment is opened in the front-back direction. It is possible to insert the tab of the mating terminal (male terminal) through the front opening and conduct.
- the second bottom wall 70 is a part of the lower wall of the main body 51 and extends in the front-rear direction and the left-right direction (width direction).
- the second side walls 71 are formed to rise from the left and right ends of the second bottom wall 70 and extend vertically.
- the second ceiling wall 72 spans from one second side wall 71A toward the other second side wall 71B and constitutes the upper wall of the second box portion 55 .
- the second ceiling wall 72 is spaced apart from the second bottom wall 70 and is inclined downward toward the front on the front side.
- the rear end of the second ceiling wall 72 forms a notch portion 73 which is recessed from above to below. As shown in FIG. 5, inside the housing 10, the end surface of the notch 73 and the lance 17 are engaged. As a result, the terminal 50 is elastically locked to the lance 17 and prevented from coming out of the cavity 16 .
- the maximum value of the distance between the lower wall (first bottom wall 57) of the main body portion 51 and the first ceiling wall 59 is defined as the height H1 of the first box portion 54.
- the maximum value of the distance between the lower wall (second bottom wall 70) of the body portion 51 and the second ceiling wall 72 is defined as the height H2 of the second box portion 55.
- the height H3 of the intermediate portion 56 is equal to or less than the height H1.
- the vertical lengths of the first side wall 58 and the second side wall 71 are set so that the height H2 of the second box portion 55 is equal to or less than the height H1 of the first box portion 54.
- the first box portion 54 that passes through the seal hole 41 first passes through the seal hole 41 while expanding.
- the intermediate portion 56 and the second box portion 55 pass through the seal hole 41 after being expanded by the first box portion 54 having the height H1. Since both the heights H2 and H3 are equal to or less than H1, the intermediate portion 56 and the second box portion 55 are less likely to get caught in the seal hole 41, and the terminal 50 can be easily pulled out. Moreover, the load applied to the second box portion 55 during the pulling process is reduced, and deformation of the second box portion 55 can be suppressed.
- the terminal 50 is formed by punching a metal plate and then bending it. Fractured surfaces formed by punching have minute burrs and irregularities. When the terminal 50 is pulled out from the housing 10 , if a burr or the like is caught on the inner peripheral surface of the seal hole 41 , the mat seal 40 will be damaged.
- FIG. 7 and 8 show a terminal 90 configured by removing the connecting portion 60 and locking wall 61 from the terminal 50 of this embodiment.
- the terminal 90 When the terminal 90 is pulled out rearward, the rear end surface 92 of the first box portion 91 contacts the seal hole 41 .
- the end surface 92 is a fractured surface that is formed when the metal plate is stamped. In the terminal 90 that does not have the connecting portion 60 and the locking wall 61, the end surface 92 is likely to get caught when the seal hole 41 is expanded, and the mat seal 40 may be damaged.
- the terminal 50 is a terminal 50 that is inserted from the rear to the front into the seal hole 41 of the mat seal 40 provided in the housing 10 and is removed from the front to the rear. 1, and the first ceiling wall 59 and the locking wall 61 are connected via a connecting portion 60 curved in the direction of the first bottom wall 57 from the rear.
- the connecting portion 60 that connects the first ceiling wall 59, which is the upper surface, and the locking wall 61, which is the rear surface, of the first box portion 54 of the terminal 50 first contacts the seal hole 41 (see FIG. 6). Since the curved connection portion 60 contacts the inner peripheral surface of the seal hole 41 and expands the seal hole 41 , the terminal 50 is less likely to get caught in the seal hole 41 . As a result, damage to the mat seal 40 during detachment and deformation of the terminal 50 due to excessive load can be suppressed.
- the plate surface of the locking wall 61 and the restricting portion 34 contact each other, thereby restricting displacement of the terminal 50 .
- the load is dispersed and the deformation of the terminal 50 can be suppressed.
- At least one of the first side walls 58A has an extension 64 extending rearward, and the rear edge 64A of the extension 64 overlaps the plate surface of the locking wall 61 when viewed in the left-right direction.
- the terminal 50 of the present embodiment includes a substantially box-shaped second box portion 55 that is spaced forward from the first box portion 54 .
- the second box portion 55 has a second bottom wall 70 , a pair of second side walls 71 rising from both ends of the second bottom wall 70 , and a second ceiling wall 72 facing the second bottom wall 70 . and the first ceiling wall 59 or less.
- the first box portion 54 (height H1) first passes through the seal hole 41 while expanding.
- the second box portion 55 (height H2) which is smaller in height than the first box portion 54 can easily pass through the enlarged seal hole 41 .
- the second box portion 55 is less likely to get caught in the seal hole 41, and the terminal 50 can be easily detached.
- the load applied to the second box portion 55 is reduced in the pulling process, deformation of the second box portion 55 can be suppressed.
- the first side wall 58A has the extending portion 64, but the first side wall 58B may have the extending portion 64.
- FIG. both of the first side walls 58A and 58B may have extensions 64 respectively.
- the terminal 50 having the second box portion 55 was illustrated, but the terminal 50 may be configured without the second box portion 55 .
- the second box portion 55 has a shape that opens forward, and the terminal 50 is a female terminal.
- the terminal 50 is not limited to a female terminal, and may be a male terminal having a tab extending forward in place of the second box portion 55 .

図3に示すように、第2箱部55は、第1箱部54とは間隔を空けた前方側に配されており、第1箱部54と第2箱部55との間には、中間部56が配されている。第2箱部55は、下方側に位置する第2底壁70と、一対の第2側壁71A、71Bと、上方側に位置する第2天井壁72と、を有している。以下の説明において、第2側壁71A、71Bをまとめて第2側壁71と表記する。本実施形態の第2箱部55は、前後方向に開口している。前方の開口から相手方端子(雄端子)のタブの挿入及び導通が可能である。
端子50は、金属板を打ち抜き加工して、その後折り曲げ加工等により成形される。打ち抜き加工によってできる破断面には微小なバリや凹凸が存在する。ハウジング10から端子50が引き抜かれる際に、バリ等がシール孔41の内周面に引っかかると、マットシール40が損傷する。
(1)上記実施形態では、第1側壁58Aが延出部64を有する場合を例示したが、第1側壁58Bが延出部64を有する構成でもよい。また、第1側壁58A、58Bの両方がそれぞれ延出部64を有していてもよい。
