- the signal conductor W1 exposed at one end of the electric wire W crosses the narrow portion 911 as shown in the top view of the chain terminal of the third embodiment of the present invention in FIG. Arranged.
- the electric wire W does not contact the carrier 91.
- the rectangular piece 92 in which the signal conductor W1 is placed on the rectangular piece main body 921 is placed in the press-molding die block M23 and further pressed. At this time, the rectangular piece 92 closes the whole rectangular piece main body 921 in which the signal conductor W1 of the electric wire W is arranged. That is, the rectangular piece main body 921 is formed so that the end portions on both sides of the rectangular piece main body 921 are close to each other.
- the rectangular piece 92 is formed in the shape of a terminal at the same time as the signal conductor W1 of the electric wire W is connected to the rectangular piece main body 921 through the above-described steps. Thereafter, the rectangular piece 92 press-molded by the mold block M23 is arranged in the press-cutting mold block M24, and the carrier cutting position shown in FIG. 7A, that is, parallel to the longitudinal direction of the electric wire W, The narrow portions 911 of the carrier 91 are cut at cut surfaces located on both sides of the signal conductor W1 of the electric wire W. In the terminal 100 formed by cutting in this way, as shown in FIG. 7B, a part of the narrow part 911 that can be regarded as a part of the carrier is formed at the rear end. In this way, the terminal 100 connected to the signal conductor W1 of the electric wire W is formed.
- the step of press-molding the rectangular piece 92 into the shape of the terminal, and the connection between the terminal and the signal conductor W1 of the electric wire W are performed. Can be performed at the same time. That is, unlike the conventional case, it is not necessary to take out a terminal formed by press molding from a mold and place the terminal in a terminal crimping apparatus including an anvil and a crimper. For this reason, when producing the electric wire with which the terminal was assembled
- the burr formed along with the cutting is also formed at the rear end of the terminal 100. As a result, it is possible to avoid the formation of a burr that prevents efficient contact with the mating terminal at the tip of the terminal 100.
- the signal conductor W1 is placed on the rectangular piece 92 provided continuously to the narrow portion 911 of the carrier 91, the electric wire W is sandwiched between the carrier 91 and the mold and is crushed during press molding. There is nothing.

Abstract
Description
(1) キャリアと、該キャリアの長手方向に延びる一端部に複数連設された、矩形状の矩形片と、を備えた連鎖端子であって、
前記矩形片が、電線の一端において露出した信号導体を包むようにプレス成形されることによって、中空筒状の端子に形成される、
ことを特徴とする連鎖端子。
(2) 前記矩形片は、前記キャリアの一端部と該矩形片の一端部を結ぶキャリアツナギを介して、前記キャリアの一端部に連設され、
前記キャリアツナギは、前記矩形片を前記キャリアを含む平面よりも高い位置に配置する形状である、
ことを特徴とする上記(1)に記載の連鎖端子。
(3) 前記キャリアの幅は、前記信号導体における露出した部分の長手方向の長さよりも小さいことを特徴とする上記(1)に記載の連鎖端子。
(4) 前記キャリアは、前記信号導体における露出した部分の長手方向の長さよりも幅が小さい幅狭部と、前記幅狭部の幅方向の長さよりも幅が大きい幅広部と、を有し、
前記矩形片は、前記幅狭部の一端部に連設される、
ことを特徴とする上記(1)に記載の連鎖端子。
上記(2)~(4)の構成の連鎖端子によれば、キャリアと矩形片の切断位置を端子の後端に位置することができるため、端子の先端に相手端子との効率的な接触を妨げるバリが形成されてしまうことを避けることができる。
図1を参照して、本発明の第1の実施形態の端子が成形される過程を、その端子の形状の変化と併せて説明する。図1(a)~(f)は、本発明の実施形態の端子がプレス成形される一連の工程を説明する図である。
矩形片12は、上述した図1(a)~(e)に示す工程を経て、電線Wの信号導体W1が矩形片本体121に接続されると同時に、端子の形状に形成される。その後、金型ブロックM4によってプレス成形された矩形片12がプレス切断用の金型ブロックM5に配置され、図1(f)に示すようにキャリアツナギ122が切断される。こうして、電線Wの信号導体W1に接続された状態の端子20が形成される。
続いて、図2を参照して、本発明の第1の実施形態の端子の構造を適用した連鎖端子を製造する方法について説明する。図2(a)は、本発明の第1の実施形態の連鎖端子を製造するための金型の斜視図、図2(b)は、図2(a)の要部の拡大図である。
第1の実施形態では、図1、図2に示すように、矩形片12の後端側(キャリア11から遠い側)に電線Wの信号導体W1の先端を載置する際、電線Wがキャリア11を横断しないように、つまり、キャリア11と電線Wの間に矩形片12が挟まれるようにしている。第1の実施形態のようにキャリア11を横断しないように電線Wを矩形片12に載置するようにすると、プレス成形の際に電線Wがキャリア11と金型によって挟まれ、押し潰されることを考慮する必要がなくなるため、下側金型40および上側金型50の型の形状をより単純なものにすることができる。さらに言うならば、電線Wの径が大きくなればなるほど電線Wがキャリア11と金型によって挟まれることを考慮する必要があるが、それが解消される。一方、キャリア11を横断しないように電線Wを矩形片12に載置する第1の実施形態では、キャリア11と矩形片12の切断位置(つまり、キャリアツナギ122の一部分)が端子20の先端に位置することになる。このため、端子20の先端に相手端子との効率的な接触を妨げるバリが形成されてしまうことが避けられない。
そこで、本発明の第2の実施形態では、キャリアとの切断によって形成されるバリが端子の後端に形成される連鎖端子80、およびその連鎖端子を構成する端子70について説明する。
矩形片62は、上述した工程を経て、電線Wの信号導体W1が矩形片本体621に接続されると同時に、端子の形状に形成される。その後、金型ブロックM13によってプレス成形された矩形片62がプレス切断用の金型ブロックM14に配置され、図5(a)に示すキャリア切断位置、つまり、電線Wの長手方向に平行な、該電線Wの両脇に位置する切断面、にてキャリア61およびキャリアツナギ622が切断される。このように切断して形成される端子70は、図5(b)に示すように、キャリアの一部とみなすことができるキャリアツナギ622の一部が後端に形成されることになる。こうして、電線Wの信号導体W1に接続された状態の端子70が形成される。
第3の実施形態もまた、キャリアとの切断によって形成されるバリが端子の後端に形成される連鎖端子110、およびその連鎖端子を構成する端子100について説明する。第2の実施形態では、電線Wがキャリア61と金型によって挟まれ、押し潰されることを回避するために、矩形片本体621とキャリア61の高さに差を設けたが、第3の実施形態では、同じ事柄を回避するために、キャリア61の幅方向の長さに特徴を持たせる。
