Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dual in-line multi-pole connector, and in particular allows easy connection of a plug inserted into a jack without deforming the plurality of connection terminals of the plug. This invention relates to a multi-pole connector that can be detached at any time.

[Conventional technology]

Basic computer equipment, OA (Office
When developing hardware or software by connecting a logic analyzer or other measuring device to a device with a built-in microcomputer, etc., using a multi-core flat cable, a dual-in-line multi-pole Many connectors are used.

In the case of a plug in such a multi-pole connector, each connection terminal to be inserted into the terminal connection hole on the jack side is thin and flexible, and a large number of them are arranged in a dual-in-line configuration, so that the jack has no contact with the jack. The contact resistance when inserting the plug is large, and a certain amount of insertion force is required. Therefore, when pulling out a plug that conventionally requires such an insertion force from a jack, a corresponding amount of pulling force is required, so generally, for example, the tip of an extraction tool such as a screwdriver is inserted into the gap between the jack and the plug when they are connected. The method used is to insert it, pry up the gap, and then pull it out.

[Problem that the invention attempts to solve]

However, the conventional method described above has the disadvantage that the plurality of connection terminals are often deformed or broken because the plug cannot be pulled out horizontally with respect to the jack.

In order to eliminate the above-mentioned drawbacks of the conventional connector, the present invention aims to provide a multi-pole connector that is easy to handle and allows the plug inserted into the jack to be easily pulled out in a horizontal position. .

[Means for solving problems]

In order to achieve the above object, the present invention provides a plug including a plurality of connecting terminals arranged vertically in two rows protruding from both sides of an insulating substrate, and a group of connecting terminals protruding from one side of the plug. Correspondingly, in a multi-pole connector consisting of a jack having a plurality of connection holes into which the group of connection terminals are inserted and connecting pins extending from the connection holes, the plugs are arranged in two rows facing each other on one board surface. a first insulating substrate having a plurality of connection terminals arranged in tandem so as to protrude and a plurality of connection holes connected to the plurality of connection terminals on the other substrate surface; A second connector with multiple connection terminals protruding from both sides that can be attached and detached correspondingly.
The insulating substrate and the plug removal mechanism interposed between the first and second insulating substrates are integrated by screwing. and a U-shaped holder that accommodates the plug removal mechanism in a built-in groove provided on the connection hole forming surface of the first insulating substrate, and has both ends extending to both sides of the second insulating substrate; It is comprised of a pair of release levers each pivotally supported by each extension of the holder and having a hook portion whose tip end is bent toward the second insulating substrate surface.

[Effect]

When the pair of detachment levers are rotated about their bending points, the plug is easily detached from the jack by the principle of leverage.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the multi-pole connector according to the present invention, and in the figure, reference numeral 1 indicates a plurality of connecting holes 2 arranged in tandem in two rows, and connecting pins extending downward from the connecting holes 2. It is a dual inline type jack with 3 protruding from it. The plug 4 paired with the jack 1 includes a terminal plate (second insulating substrate) having a plurality of connecting terminals 6 protruding from both sides corresponding to the connection hole group 2 of the jack 1, and both ends of a holder 8a. hook portions 8c, 8 whose tips are bent inward and interposed between the plug 4 and the jack 1;
A detachment mechanism 7 is formed by pivoting detachment levers 8b and 8b' each having a diameter c' and an insulating substrate 10.
A plug comprising a built-in groove for accommodating the holding body 8a on the lower surface thereof, a group of connecting holes (not shown) corresponding to the connecting terminal group 6 of the terminal plate 5, and a connecting pin 11 protruding from the upper surface of each of the connecting holes. Main body (first
An insulating board) 9 is integrally screwed together with screws 12, and two sets of connecting pins 11 of the plug body 9 are connected via a cable connecting printed board 13 in this case. flat cable connectors 14 and 15 are attached.

Incidentally, the plug in a conventional multi-pole connector is constructed by screwing the terminal board 5 and the plug body 9 together with a screw 12, and then attaching the flat cable connector 14 via a printed board 13 for cable connection. , 15 are attached, and there is no provision for mechanically removing the plug from the jack 1, so removal is not easy and, as mentioned above, there is the problem of deforming the connection terminal group 6 of the plug. It was hot.

Now, plug 4 of the multi-pole connector according to the present invention.
As described above, since the detachment mechanism 7 is attached to the plug 4, the plug 4 to which the flat cables 16 and 17 are connected is connected to the printed board 18 on the device side, for example, as shown in the cross-sectional view of the main part in FIG. When the plug 4 is attached to the jack 1 attached to the plug 4, the hooks 8c and 8c' at the tips of the release levers 8b and 8b' of the release mechanism 7, which is integrally formed with the plug 4, connect the plug 4 and the jack 1. The connection is reliably established with the media interposed between the two. Therefore, when pulling out the plug 4 from the jack 1 next time, the plug 4
Both detachment levers 8b, 8 are integrally connected to the
If you hold b' with your fingers and press it in the direction of the arrow, the hooks 8 of the release levers 8b and 8b'
c and 8c' are pushed down to the opposite surface of the jack 1 by lever action using the support shafts 8d and 8d' as fulcrums, respectively, and as a result, the plug 4 is pushed up horizontally in the direction to be pulled out from the jack 1 and is easily pulled out. can leave. At this time, since the connection terminal group 6 of the plug moves vertically, there will be no accident of deformation or breakage.

In addition, even if one or more connecting terminals 6 of the plug 4 are broken due to this frequent insertion/removal operation, the terminal board 5 that integrates the terminal group can be removed by removing the two screws 12 and removing the plug body. 9, the terminal group of the plug can be easily repaired by replacing it with a new terminal board.

[Effect of idea]

As is clear from the above explanation, according to the multi-pole connector of the present invention, the plug can be easily and horizontally removed from the jack with a single touch operation, making the plug removal operation extremely easy. At the same time, the risk of deforming or breaking the plurality of jack insertion connection terminals on the plug side is eliminated. Furthermore, the plug has a compact structure and has a separated structure that allows the connecting terminal group to be easily replaced, so that it has the advantage that even if it is deformed or broken, it can be easily repaired. Therefore, it exhibits excellent effects when applied to multi-polar connectors that are frequently disconnected.
