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 the Invention 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 terminals, the connecting wires get tangled, making the work difficult, and since there are so many types of terminals, a great deal 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, although each of the terminal storage chambers a and b is provided with known locking means such as a locking arm for the terminal (not shown), it is difficult to confirm because the number of poles is extremely large, and it is difficult to confirm the locking means. There is also a risk that it may be overlooked while it is completely inserted and may come off during use.

An object of the present invention is to solve the above-mentioned problems, to consolidate connectors, and to facilitate terminal insertion work.
To provide a high-density multi-pin connector that can prevent incomplete insertion and deviation of terminals, and can easily increase or decrease the number of pins depending on vehicle type, class, etc.
The solution is that several multi-pole connectors are connected vertically or horizontally and combined into one, and the outer wall of each combined connector has a plurality of through holes facing the internal terminal housing chamber. are provided, and the plurality of through holes are removably blocked by a rear holder formed by protruding a terminal presser rod inserted through each through hole from a common board for each of the combined connectors. It is characterized by

Multi-pole connectors can be connected by providing a frame with a connector fitting part and fitting them together, by providing a push-in member and its fitting member' between adjacent housings, or by fixing the housings together with adhesive. It's okay.

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 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 addition, by providing a through hole in the housing side wall of the multi-pole connector facing the terminal housing chamber, and by removably inserting and inserting a rear holder consisting of a terminal holding bar protruding from the common board for each multi-pole connector, A fully inserted terminal can be easily checked and its displacement is also prevented.

Embodiment In FIG. 1, M indicates a male high-density multi-polar connector, and F indicates a female high-density multi-polar 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 as shown in Fig. 2 a''-c.
It is integrally formed in the rear half of the connector housing IA, and has fitting openings 6 and 7 for the connector housing IB and IC on the upper and lower sides thereof. On the side wall of the fitting opening 6.7,
A flexible locking arm 8 is formed and can be locked by engaging with a locking groove 9 recessed in the side wall of the connector housing IB, 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 presser bars 13, each connector housing I
A vertical groove 14 for accommodating the common substrate 12 is recessed in the left and right side walls of A-1c, and a plurality of through holes 15 are opened in the vertical groove 14.

Reference numeral 16 denotes a nand 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 female 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,
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
It has four tab-shaped contacts 25 on both sides. 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 90' in accordance with the arrangement of the terminal storage chamber 20.

Further, in the center of the connector housing 18, a bolt 26 is attached via a bolt holder 27 for tightening the male high-density polarized connector M to the naso 1-17. A guide frame 28 (see FIG. 3) for the Nando holder 16 is formed in the holder.

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 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, 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 insertion and connection with the male 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.

Furthermore, since the rear holder 10.11 has its terminal presser foot 13 integrally protruding from the common board 12, the board 12 is fitted into the vertical groove 14 and the connector housings IA to IA
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 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 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 coductor M moves forward toward the connector F side, and even though the female and jj I terminals 5 (5') and 21 have an extremely large number of poles, they fit smoothly. If so, you can connect. Note that if such bolts 26 and nuts 17 are not provided, the connectors (housing) IA, IB, I
C can be fitted together individually, and the work can be easily carried out in the same way as a normal multi-pole connector, and the advantages of the combined high-density multi-pole connector are exhibited here as well.

Next, since the aforementioned branch terminals 23 and 23' are incorporated in the terminal housing 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), it is necessary to perform a joint 31 between the electric wires 4 led out from the female high-density multi-pole connector C, as shown in FIG. 6a. was there. 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 Figure 6, the conventional joint wire 4' is abolished.As a result, there is no joint between wires connected to different connectors, so the circuit can be divided and assembled. can reduce the production cost of wire harnesses.

Figures 7a"-e" respectively show other embodiments of branch terminals applicable to combined connectors.

That is, the branch terminals 31 and 32 shown in a and b are as follows:
The part of the contactor 25 of the H-type branch terminal 23 shown in FIG.
One that is bent into a shape (al), one that has the contactors 25 on both sides bent in an L shape in opposite directions (bl), and one that is C
The branch terminals 33, 34, and 35 shown in ~e are each punched into a double H 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 IA 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 connected and combined into one to form one high-density multi-pole connector, so that it is possible to consolidate 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. In addition, since the rear holder common to each combined multi-polar connector is detachably inserted into the connector, incomplete insertion and detachment of the terminal can be prevented.
