Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-density multipolar connector used for connecting wire harnesses and the like.

Conventional wire harnesses generally have a structure in which a large number of electrical wires are bundled together with tape, and branch lines are led out from the main line. The female or male connector provided at the end is connected to male or female connectors provided on various electrical components.

However, according to such a female and male connector connection method,
In areas such as automobile instrument panels where a large number of switches and meters are concentrated, there are a large number of connectors, and connecting them requires a great deal of effort and time, and occupies a large amount of space.

Therefore, as shown in FIG.
, d, it is also possible to consolidate a large number of conventional connectors with a small number of pins for each type of electrical equipment.

Problems to be Solved by the Invention In the above-described high-density multipolar connector, a large number of terminal accommodation chambers a and b are integrally formed.

Therefore, when inserting the terminal, the connecting wires become tangled, making it difficult to insert the terminal, and since the terminal has too many poles, a large amount of force is required to engage and disengage the connectors c and d.

In addition, since the terminal accommodation chambers a and b are integrally molded, if the number of circuits is small due to differences in vehicle type, class, etc., a large number of empty spaces will be created, resulting in waste. If connectors were manufactured using the same methods, the number of products would increase, making management difficult.

Furthermore, since the above-mentioned high-density multi-pole connector does not have a branch connection function, it is necessary to make a branch connection using crimp terminals or the like between the wires connected to the terminal, which makes the work much easier. It's a hassle.

Means for Solving the Problems An object of the present invention is to solve the above problems, to consolidate connectors, and to facilitate the insertion of terminals.
To provide a high-density multi-pole connector that can reduce the production cost of wire harnesses by having an internal branch connection function, and that can easily increase or decrease the number of poles depending on vehicle type, class, etc. The solution is to connect a pressure-type high-density multi-pole connector that accommodates a large number of female terminals to a female-type high-density multi-pole connector that accommodates corresponding male terminals, thereby electrically connecting the female, m, and m terminals. In the connector that performs the connection, at least one of the male type and female type high-density multi-pole connector is formed by connecting several multi-pole connectors vertically or horizontally and combining them into one, and at least one Is it possible to connect the female terminals on both sides of the connecting piece? It is characterized by having a branch terminal with 3I tab-shaped contacts protruding from it.

Multi-pole connectors can be connected by providing a frame with a connector fitting part and fitting them together, by providing an insertion member and its fitting member between adjacent housings, or by bonding the housings together. It may be fixed with an agent.

Function The high-density multi-pole connector of the present invention is one in which several multi-pole connectors are fitted into the fitting opening of the frame body and combined to form one high-density connector, so that the effectiveness of the aggregation is improved. At the same time, by limiting the number of poles per multi-pole connector to be fitted, it is possible to eliminate difficulties caused by entanglement of connecting wires when inserting the terminal.

In addition, among the several multi-pole connectors, one connector is dedicated to the basic electrical component circuits and branch circuits for distributing power, regardless of the car model or class, and the rest are dedicated to the branch circuit for distributing power, regardless of the car model or class. By using the present invention for circuits to be revised or abolished, such as room lamp control units, diffuser control units, etc., it is possible to easily construct a high-density multi-pole connector with a number of poles corresponding to specifications.

Furthermore, the number of pins of the multi-pole connectors to be combined can be selected according to the specifications of the vehicle type, grade, etc., so that there is no vacant space in the terminal accommodation chamber.
There is no waste and no terminal connection errors occur.

In addition, since the connector is equipped with a branch terminal,
Since the conventional branch connections between wires can be omitted, the work of stripping the wires and crimping the conductors using crimp terminals can be greatly reduced, helping to reduce the production cost of wire harnesses.

In FIG. 1, M indicates a male high-density multi-pole connector, and F indicates a female high-density multi-pole connector.

The male high-density multi-polar connector M is constructed by combining three multi-polar connector housings IA, IB and IC made of an insulating material into one by a frame 2. A female terminal 5 connected to the terminal of the electric YA4 is inserted into the terminal accommodating chamber 3 of each connector housing, and is locked by known means.

In this embodiment, the frame body 2 is formed integrally with the rear half of the connector housing IA, as shown in FIGS. A flexible lock 115i!8 is formed on the side wall of the fitting opening 6.7, and engages with a lock groove 9 recessed in the square wall of the connector housing IB, IC. It can be locked.

Reference numerals 10 and 11 are carrier holders for preventing the female terminal 5 from coming off backwards, and are comprised of a plurality of terminal presser rods 13 protruding from a common board 12 in a comb-teeth shape. Corresponding to these terminal presser bars 13, each connector housing I
A vertical groove 14 for accommodating the common board 12 is recessed in the left and right (=J walls of A to IC), and a plurality of through holes 15 are formed in the vertical groove 14.
is open.

Reference numeral 16 denotes a seat holder projecting from the center of the connector housing IA, into which a nut 17 is embedded and fixed. In addition, the upper connector housing IB
A female terminal 5' for power distribution is inserted and fixed therein.

": The #-type high-density multi-pole connector F is integrally formed with connector housings 18 corresponding to the connector housings IA to IC constituting the male-type high-density multi-pole connector M, and the connector M is attached to the front end thereof. Mantle body part 1 for fitting
9 is provided.

In the terminal housing chamber 20 of the connector housing 18,
The female terminal 21 corresponding to the female terminal 5 is inserted and fixed. The connector housing 18 has a rearward projection 22 at the top. In this rear projection 22, a branch terminal 23 or 23' as shown in FIGS. 4a and 4b is further secured from the fitting side by press-fitting or other means.

The branch terminal 23 is a bus bar formed by punching a rigid sheet metal such as brass into an H shape, and the connecting piece 24
It has four tab-shaped contacts 25 on both sides. The branch terminal 23' is formed by bending the contact 250 portion at right angles to the connecting piece 24 to form a U-shape. There are locking protrusions 24a on both sides of the connecting piece 24 of each terminal, and
A press-fit locking protrusion 25a is provided at the base end of the tab-shaped contact terminal 25 on one side. Note that 20a is a connecting piece 24 provided between the terminal accommodation chambers 20 and 20.
This is a slit for insertion into. Thereby, the insertion angle of the female terminal 5' can be changed by 906 in accordance with the arrangement of the terminal storage chamber 20.

Further, a bolt 26 is attached to the center of the connector housing 18 via a bolt holder 27 for tightening the nut 17 of the male high-density multi-pole connector M, and the fitting end of the bolt holder 27 is A guide frame 28 (see FIG. 3) for the nut holder 16 is formed.

On the other hand, locking holes 29 are formed in the upper and lower circumferential walls of the housing portion 19 of the connector F, and the locking holes 29 are engaged with locking claws 30 protruding from the outer peripheral walls of the connector housing IB and IC of the connector M, and are temporarily locked. It is now possible to do so. In addition, in Fig. 3, 10' and 11' are connectors F.
14' indicates a vertical groove, and 15' indicates a through hole for mounting the carrier holder.

Next, male and female high-density multi-pole connectors M.

The assembly of F and its function will be explained.

The connector M is connected to the connector housing IB in parallel to the insertion direction of the electric wire 4 into the fitting openings 6 and 7 of the frame body 2 formed integrally with the connector housing IA.

When IC is fitted, the flexible locking arm 8 engages with the lock 'a9', and as shown in FIG.

Next, the terminal presser rods 13 of the rear holder 10.11 are inserted through the left and right through holes 15 of each of the housings IA to IC. At this time, if each housing is not installed in the correct position, the vertical grooves 14 will not be aligned and a single groove will not be formed, making it impossible to insert the terminal presser rod I3. The female terminals 5, 5' are pulled through the wire 4,
Or even if it is pushed backwards when connecting with the male terminal 21, the terminal presser rod 13 acts as a stopper,
Its removal is prevented. Also, if one of the female terminals 5 or 5' is incompletely inserted and protrudes from the terminal accommodation chamber 3 or 3', the presser rod 13
Since it is not possible to insert the female terminal 5, 5'
can prevent incomplete insertion.

Further, since the rear holder 10.11 has its terminal presser rod 13 integrally protruding from the common board 12, the board 12 is fitted into the vertical groove 14 and the connector housings IA to I
It has the effect of preventing wobbling between C.

The connector housing IB and the IC can be fitted into the frame 2 after inserting and fixing the female terminals 5, 5' into the respective terminal housing chambers 3 or 3', so that a large number of electric wires 4 do not become entangled. , easy to work with.

When this connector M is lightly fitted into the housing portion 19 of the connector F, the locking claw 30 and the locking hole 29 engage, and both connectors M and F are temporarily locked.

At the same time, the tip of the NAND holder 16 enters the guide frame 28 at the tip of the bolt holder 27, as shown in FIG.

Therefore, when tightening the connector F, by rotating the bolt 26, the connector M advances toward the connector F side, and despite the extremely large number of female and male terminals 5 (, 5') and 21, the connector M can be tightened smoothly. Can be mated and connected. Note that if such bolts 26 and nuts 17 are not provided, the connectors (housings) IA, IB, and IC
The advantages of the integrated high-density multi-pole connector can be demonstrated here as well, as it is only necessary to fit them together individually, and the work can be easily carried out in the same way as a normal multi-pole connector.

Next, since the above-mentioned branch terminals 23 and 23' are incorporated in the terminal storage chamber 20 of the connector F, the wiring form of the electric wires connected to the connectors M and F can be simplified. That is, in the conventional high-density multi-pole connector (see FIG. 8), as shown in FIG. There was a need. In addition, 3
2 indicates an external connector. However, the connector F in this embodiment has branch terminals 23, 23 . By inserting the female terminal 5' into the contact 25, the joint 31 is absorbed into the inside of both connectors F and M, as shown in FIG. 4' is eliminated.As a result, there is no joint between the wires connected to different connectors, so the circuit can be divided and assembled, and the production cost of the wire harness can be reduced.

Figures 7a to 7e show other embodiments of branch terminals, each applied to a combined connector.

That is, the branch terminals 31 and 32 shown in a and b are as follows:
The contactor 25 on one side of the H-type branch terminal 23 shown in FIG.
(a) with the contacts 25 on both sides bent into an L shape in opposite directions (bl);
The branch terminals 33, 34, and 35 shown in "-e" are each punched into a double L shape with three contacts 25 on both sides of the connecting piece 24, and C is the connecting piece 24.
Both of them are bent into a U-shape, d is one of the connecting pieces 24 is bent into an L shape, and the contact 25 part of the L-shaped bent part is bent outward, and e is bent inward. upper and lower contacts 25
The two are arranged to face each other.

In this way, the number of poles of the contacts 25 provided on the connecting piece 24 can be freely increased or decreased as necessary, and the three-dimensional arrangement of the contacts 25 can be changed by arranging the corresponding terminal accommodation chambers 20. .

In the above, an example has been described in which the connector housing IB and IC of the connector M are fitted into the frame 2 from the wire insertion direction. It is also possible to open the upper and lower peripheral wall portions of the frame 2 to form an H shape, and to fit the wires in a direction perpendicular to the wire insertion direction. Furthermore, it goes without saying that the frame body 2 and the connector housing IA can be formed separately, or the connector F can be formed in an integrated manner like the connector M.

As is clear from the above, according to the present invention, several multi-pole connectors are connected and combined into one to form one high-density multi-pole connector. While aiming to consolidate the terminals, we eliminate the difficulty of inserting terminals due to the increase in number of pins, and by changing some parts of the multi-pin connectors that are combined, we can increase or decrease the number of pins, creating a high-density multi-pin connector that eliminates waste. can be provided. Further, by providing a branch terminal having a branch connection function in the connector, branch connections between electric wires can be omitted, and the production cost of the wire harness can be reduced.
