Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a thread, a screw 2, and a wire harness 9 that make it possible to simplify the manufacturing process of automotive wire harnesses using an automatic wiring machine. Related, also, )-C exists.

With the current automatic wiring machine manufacturing technology for wire harnesses, (i) place the terminal fittings in a case called a magazine, and (b) place the wires of the required size and color in the predetermined positions. □Cut the wires to the required length (c) remove the insulation, (d) tighten the wires to the terminal fittings in (b), (e) remove the magazine, and (c) ) This is done by inserting the terminal fittings into the predetermined positions of the connector housing. In this case, if you insert the terminal fitting into the magazine without putting it into the connector housing from the beginning, the crimped part of the wire will be hidden inside the connector body, making it impossible to connect the wire. □It's for the sake of it.

However, with such conventional known technology, it is necessary to remove the magazine and then insert the terminal fitting into the connector housing, and many defective products occur due to the insertion of the terminal fitting. I spend a lot of time repairing it with □.

In addition, as shown in Figure 1, when crimping the terminal metal fitting placed on the male die a and the electric wire C, the width of the female die d, which has a U-shaped groove, is designed to be 8 mm or more. The pitch of the necessary terminal fittings parallel to the connector housing is also 13m.
m or more, but in reality, as connector housings become smaller, there are many connectors whose terminal fittings have a pitch of 73 This has the disadvantage of doubling the work.

The present invention has been made by focusing on the above-mentioned points, and involves inserting and locking the terminal fitting into the connector housing with the wire crimping part exposed, and then applying the wire by the wire crimping part. In this case, the connector housing is composed of a housing body block and a combination terminal accommodating block, and terminal accommodating compartments are provided at every other pitch on both of them, and when the two are combined and connected, the terminal accommodating compartments are By inserting or crimping the terminal fittings into the housing block and the combination terminal housing block separately, it is possible to prevent the terminal fittings from being inserted into the connector housing. Final terminal fitting pitch is 13m
This makes it possible to easily carry out caulking and connection work even when the diameter is less than m.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral A indicates a male connector housing, and reference numeral B indicates a female connector housing, which are assembled by fitting into each other.

Male connector housing A is housing body block AI
, a combination terminal housing block A2, and a cover A3 . Made of A4, female connector housing B
The housing main body block B1 consists of a combination terminal accommodating block B2, a cover 83, and B4.

Housing body block A+ of male connector housing A
is for accommodating a 4-pole terminal fitting C, and z
A fixed terminal accommodating compartment body 1゜1 and two terminal accommodating compartment support parts 2, 2 are provided alternately, and a terminal accommodating part for combination is provided with respect to the terminal accommodating compartment support parts 2, 2. Separated terminal receiving compartments 1', 1 in block A2
' are fitted together, so that four terminal accommodating compartments are arranged in parallel, and at this time, the locking pieces 3 of the combination terminal accommodating block A2 are connected to the connecting body block A+
The locking protrusion 4← comes together and the combined state of both is maintained. ,.

The cover A3, which is coupled to the rear half of the housing body block Al, has a locking protrusion 5t on the outer surface of the terminal accommodating section 1, 1'. A locking hole 6 corresponding thereto is formed, and a locking portion 8 for a flexible locking piece 7 of one inch A4 connected to the other side of the rear half of the housing main body block A+ is inserted, and a locking portion 8 for a flexible locking piece 7 of the length A4 is engaged. A3 and A4 work together to maintain the state of connection to the housing body block A1. and,
The cover A4 is provided with a rear holder 10 which is connected to the terminal fitting C, through which the electric wire W is inserted, and which engages with the electric wire and the crimping portion 9 of the terminal fitting C.

Flexible locking arms 12 are provided on both sides of the housing body block 1 to engage with the sleeve portion 11 of the female connector housing B (7).

Housing body block BI of female connector housing B
is for accommodating a four-pole terminal fitting, and two fixed terminal accommodating compartment bodies 13.13 and two terminal accommodating compartment support parts 14, 14 are provided alternately. The separated terminal accommodating compartment 13 in the terminal accommodating block B2 for combination with respect to the terminal accommodating compartment support part lj, 14
', 13' are fitted together so that four terminal accommodating blocks are arranged in parallel. The combined state of the two is maintained by engaging with the locking protrusion 16 at.

A locking hole 18 for the locking protrusion 17 on the outer surface of the terminal accommodating section 13, 13' is formed in the cover B3 that is coupled to the rear half of the housing body block B1, and a locking hole 18 is formed in the cover B3 that is coupled to the rear half of the housing body block B1. With respect to the flexible locking piece 19 of the cover B4 coupled to the other side. Locking part 20
is provided, and a double force bar 83. B4 cooperates to maintain the state of connection to the housing body block Bl. The cover 84 is provided with a rear holder 22 that engages with the wire clamping portion 21 of the terminal fitting.

A locking hole 23 into which the locking arm 12 of the male connector housing A engages is formed in the sleeve portion 11 of the housing body block BI.

In the above configuration, in order to assemble the male connector housing A, each terminal accommodating section 1 of the separated housing main body block A1 and the combination terminal accommodating block A2,
Insert the terminal fitting C into 1' and lock the wire crimping part 9 with the flexible locking arm 24 (Fig. 3A), then tighten the wire crimping part 9. Connect the electric wire to the terminal fitting C, and insert the cover A3. A4 is destroyed (Fig. 3), and the flexible locking piece 19 locks the connected state (Fig. 2), and the rear holder lO engages with the wire crimping part 9 to prevent the terminal fitting C from coming off. to prevent.

Note that the female connector housing B is assembled in the same manner.

The present invention is constructed as described above. Therefore, with the terminal fittings inserted into the connector housing part, the electric wires can be crimped and connected using an automatic wiring machine, and in this case, the feature can be easily performed even if the pitch of the terminal fittings is 13 mm or less. has.
