Description

  The present invention relates to a shield connector.

  Conventionally, as a shield connector, first, in order to connect an electric wire, after connecting the wire terminals to each other at the upper part of the housing, a metal cover is put on the upper side of the housing (the following, patent Reference 1).

JP 2001-250642 A

  By the way, when the extension direction of the electric wire terminal to be connected is not a coaxial direction but different directions such as orthogonal directions, a connector with an L-shaped terminal fitting attached to one electric wire terminal is used. It can be connected to the connector etc.

  Specifically, as shown in FIG. 47, the end portion of the electric wire 2 is arranged on the horizontal upper surface of the housing 1, and the press-fitting hole is in a downward direction that is a direction orthogonal to the extending direction of the electric wire 2. The bent tip portion 3A of the L-shaped terminal fitting 3 is press-fitted into the press-fitting hole. The upper portion of the housing 1 is covered with a shield cover 4 made of aluminum die cast.

Here, as a method of attaching the L-shaped terminal fitting 3 to the housing 1, first, the barrel of the terminal fitting 3 is pressure-bonded to the end portion of the electric wire 2 through the rubber plug 5. Then, with the shield cover 4 removed, the tip portion 3A is press-fitted into the press-fitting hole from above the housing 1.
And when the surplus part of the electric wire 2 in the upper part of the housing 1 is pulled back to the outside and then the shield cover 4 is put on, a shield connector is manufactured.
Thus, when using an L-shaped terminal, the complicated operation | work of pulling back the electric wire 2 after press-fitting outside at the time of manufacture of a shield connector is needed.

  Moreover, since the upper surface of the housing 1 to which the terminal metal fitting 3 is attached needs to be opened for press-fitting, a strong aluminum die-cast shield cover 4 is necessary to protect the electric wire terminal arranged there. However, since this aluminum die-cast shield cover 4 is expensive, there has been a demand for using a thinner and cheaper shield member.

  The present invention has been completed based on the above circumstances, and a shield connector in which the tip end portion of the terminal fitting is formed in a direction different from the wire insertion direction without requiring complicated work and high cost. The purpose is to provide.

The shield connector according to the present invention includes a housing, a terminal end of the electric wire connected to the base end side metal fitting having a connection insertion hole, and a distal end side of the base end side terminal metal fitting. A distal end side metal fitting, a connecting member that is inserted through the coupling insertion holes to connect the proximal side terminal metal fitting and the distal end side metal fitting, and a shield shell that covers the housing. Is provided in a direction different from the axial direction of the base end side terminal insertion hole, and the base end side terminal insertion hole, A mounting insertion hole through which the connecting member can be inserted, and the distal end side terminal fitting inserted through the mounting insertion hole is press-fitted and fixed to the housing, and the fixed distal end terminal Front to bracket The base end side terminal fittings inserted through the base end side terminal insertion holes are overlapped, and the connecting member has bolts inserted through the connection insertion holes, and screw groove portions screwed into the bolts. It consists of a nut formed on the peripheral surface, and the bolt inserted from the attachment insertion hole is inserted into the both connection insertion holes and is screwed into the nut .

  According to the said structure, the terminal part of an electric wire is attached to the base end side terminal metal fitting, and the base end side terminal metal fitting is inserted in the base end side terminal insertion hole. On the other hand, the distal end side terminal fitting is inserted into the attachment insertion hole, and the proximal end side terminal fitting and the distal end side terminal fitting are connected by a connecting member.

Thereby, since it is not necessary to press-fit an L-shaped terminal or the like, it is possible to eliminate a complicated work of pulling back the electric wire after press-fitting. Moreover, since it is not necessary to open the upper part of the housing for press-fitting, it is possible to use a relatively thin and inexpensive shield shell instead of covering the upper part of the electric wire terminal with a strong shield cover. Therefore, it is possible to provide a shield connector in which the tip end portion of the terminal fitting is formed in a direction different from the electric wire insertion direction without requiring complicated work and high cost.
In addition, the base end side metal fitting and the distal end side metal fitting can be connected with a simple configuration.
In addition, the tip side terminal fitting can be fixed to the housing with a simple configuration.

In addition, it is good also as following structures.

In addition, since it is not necessary to open the portion where the wire terminal is arranged above the housing for press-fitting, a relatively thin and inexpensive shield shell is used instead of covering the upper portion of the wire terminal with a strong shield cover. Can be used. Therefore, it is possible to provide the shield connector 10 in which the tip end portion of the terminal fitting is formed in a direction different from the electric wire insertion direction without requiring complicated work and high cost.

(2) Since the mounting insertion holes 24A to 24C are provided in a direction orthogonal to the axial direction of the terminal insertion holes 22A to 22C, the connection state can be maintained firmly.

(3) Since the connecting member 70 includes a bolt 71 inserted into the connecting insertion holes 44 and 64 and a nut 72 having a thread groove portion 73 screwed with the bolt 71 formed on the inner peripheral surface, the connecting member 70 has a simple configuration. Thus, the proximal end terminal fitting 40 and the distal end side fitting 50 can be connected.

(4) Since the nut insertion portion 27 that accommodates the nut 72 in the rotation restricted state is provided in the attachment insertion holes 24A to 24C, the bolt 71 can be easily screwed into the nut 72.

(5) The front end side metal fitting 50 is formed with a nut holding portion 52 that holds the nut 72. Therefore, when the nut holding part 52 holds the nut 72, the nut 72 can be easily accommodated in the nut accommodating part 27 and the detachment of the nut 72 can be restricted.

(6) Since the distal end side terminal fitting 50 is press-fitted and fixed to the housing 20, the distal end side terminal fitting 50 can be fixed to the housing with a simple configuration.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.
(1) In the said embodiment, although the connector 10 shall be attached to the one end side of EPS harness H, it is not restricted to this, It can apply also to the connector attached other than EPS harness H. Moreover, it is also possible to use it for the connector used other than a vehicle.

  (2) In the above embodiment, the distal end side terminal fitting 50 is formed in the direction orthogonal to the extending direction of the electric wire 11 terminal. However, the present invention is not limited to this, and the electric wire 11 terminal in a direction other than the orthogonal direction. It is good also as a structure by which the front end side metal fitting 50 (axial direction of an attachment penetration hole) is formed toward a direction different from the extending direction (axial direction of terminal penetration holes 22A-22C).

( 3 ) In the above embodiment, the collar 78 is arranged in the through hole 34 of the flange portion 33 of the housing 20, but the collar 78 may not be provided. For example, as shown in FIG. 46, an extension through hole 196A extending into the through hole 34 of the flange portion 33 of the housing 20 is formed in the connection support plate 196, and the tip of the extended through hole 196A ( The lower end may be abutted against the case CA.
