Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a high-density multipole 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 Akira In the above-described high-density multi-pole connector, a large number of terminal housing 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 vacant rooms will be created and will be wasted. If connectors were manufactured at the same time, the number of products would increase, making management difficult.

Means for Solving the Problems An object of the present invention is to solve the above problems, to consolidate connectors, and to facilitate terminal insertion work.
Moreover, the purpose is to provide a high-density multi-pin connector that can easily increase or decrease the number of pins depending on the type of car, class, etc., and the solution is to provide a frame body with a plurality of connector fitting parts, and the connector The present invention is characterized in that a multi-polar connector is fitted into the fitting part, and these inter-row connectors are combined to form one connector.

The above-mentioned frame body can be formed, for example, integrally with one multipolar connector housing, that is, so as to surround the housing, or can be formed completely separate and independent from the housing.

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 a 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 a circuit to be revised or abolished, such as a room lamp control unit, a defogger control unit, etc., a high-density multi-pole connector with a number of poles corresponding to specifications can be easily constructed.

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 Figure 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 end of the electric wire 4 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 integrally formed in the rear half of the connector housing IA, as shown in FIGS. 2A to 2C.
The connector housing IB has fitting openings 6 and 7 for the IC on the upper and lower sides thereof. A flexible locking arm 8 is formed on the side wall portion of the fitting opening 6.7, and the connector housing I
B. It can be locked by engaging with a locking groove 9 recessed in the side wall of the IC.

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-like shape. Corresponding to these terminal retainers 13, each connector housing L
A vertical groove 14 for accommodating the common substrate 12 is formed in the left and right side walls of the A-IC, and a plurality of through holes 15 are formed in the vertical groove 14 .

Reference numeral 16 denotes a nut 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 lB
A female terminal 5' for power distribution is inserted and fixed therein.

The female high-density multi-pole connector F is integrally formed with a connector housing 18 corresponding to the connector housing IA-1c constituting the male-type high-density multi-pole connector M,
A housing portion 19 for fitting the connector M is provided at the front end thereof.

In the terminal housing chamber 20 of the connector housing 18,
The male 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
Four tab-shaped contacts 25 are placed on both sides of the holder. The branch terminal 23' is formed by bending the contact 25 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 Nando 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 multipole 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 the IC is fitted, the flexible locking arm 8 engages with the locking groove 9, and as shown in FIG.

Next, the terminal retainers 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, so the terminal presser rod 13 cannot be inserted. The female terminals 5, 5' are pulled through the wire 4,
Or, even if the terminal is pushed backwards during fitting and connection with another terminal 21, the terminal presser rod 13 acts as a stopper and prevents the terminal from being pulled out. Furthermore, if one of the female terminals 5 or 5' is incompletely inserted and protrudes from the terminal accommodation chamber 3 or 3', the presser bar 13 cannot be inserted. Incomplete insertion of 5' can be prevented.

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 #1 groove 14 of the connector housing IA.
~ It has the effect of preventing looseness between ICs.

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 sleeve 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 nut 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
Can be fitted and connected smoothly. Note that if such bolts 26 and nuts 17 are not provided, the connectors (housings) LA, IB, and IC may be fitted individually to the connector F, and they can be easily fitted in the same way as normal multi-pole connectors. This is where the advantages of a combined high-density multipole connector can be realized.

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 made into a cylindrical structure. That is, in the conventional high-density multi-pole connector (see Fig. 8), as shown in No. 6 UjB a,
Electric wire 4 led out from the female high-density multi-pole connector C
It was necessary to perform joint 31 between each other. Note that 32 indicates an external connector. However, since the connector F in this embodiment has the branch terminals 23 and 23', by inserting the female terminal 5' into the contact 25, the joint 31 is formed inside both connectors F and M. As shown in FIG. 6, the conventional joint line 4' is eliminated. As a result, there are no joints between the electric 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.
It is bent into a shape (al, fb is made by bending the contactor 25 portions on both sides into an L shape in opposite directions). Also, C
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 in C, both connecting pieces 24 are formed in a U-shape. d is one of the connecting pieces 24 bent into L.
It is bent into a shape, and the contact 25 portion of the L-shaped bent portion is bent outward, and e is bent inward so that the upper and lower contacts 25 are opposed to 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 LA can be formed separately, or the connector F can be formed in an integrated manner like the connector M.

Effects of the Invention As is clear from the above, according to the present invention, several multi-pole connectors are combined using a frame to form one high-density multi-pole connector, so that it is possible to consolidate the connectors. By eliminating the difficulty of inserting terminals due to multi-pole design, and increasing or decreasing the number of pins by changing some of the multi-pole connectors that are combined, we provide a high-density multi-pole connector with no waste. be able to.
