Description

Cable-side electrical connector {ELECTRICAL CONNECTOR ON CABLE SIDE}

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a cable-side electrical connector, and more particularly, to a mating connector attached to a circuit board from a direction perpendicular to the face of the circuit board so that the connected cable is parallel to the face of the circuit board. It relates to an elongated electrical connector.

As this kind of connector, what is disclosed by patent document 1 is known. This well-known connector is attached with the metal shell which shields on the upper surface on the opposite side to the attachment surface to a circuit board. The metal shell is also bent to the side of the side of the connector, and has a leg-shaped engaging piece that is parallel to the side and extends toward the side of the circuit board, and the engaging piece engages in locking engagement with the mating connector. Protrusions are formed at the leading end positions of the locking pieces in the extended direction (see Patent Document 1, Fig. 1).

[Patent Document 1] Japanese Laid-Open Patent Publication No. 2006-244732

This type of connector attached to a circuit board is required to reduce the height, that is, to reduce the height dimension in a direction perpendicular to the surface of the circuit board, for the purpose of miniaturization of the electronic apparatus mounting the circuit board. do. Therefore, the cable connected to this connector also extends in the direction parallel to a circuit board, and is accommodated in the height dimension of a connector. Therefore, although the height reduction of the connector of the patent document 1 is requested | required, since the fitting of the connector is made in the height direction of a connector, the said engaging piece which extends in this direction and has a protrusion at the front end side is a connector. It is only possible to extend the height range to a maximum length, and as a result, the locking piece cannot secure a sufficient length and the amount of deflection displacement at the tip is small. This leads to failure to obtain sufficient elasticity for locking engagement with the mating connector. Moreover, since the locking piece, which is not of sufficient length, is made of a part of the metal shell, it has a relatively high rigidity and makes it difficult to secure elasticity.

An object of the present invention is to provide a cable-side electrical connector that is capable of sufficiently securing a displacement amount in a lock portion for locking engagement while being a height-reducing connector.

In the cable side electrical connector according to the present invention, the cable connected to the cable side electrical connector extends at a right angle with respect to the connector fitting direction with the mating connector, and the lock lever performs the fitting lock with the mating connector and release of the lock. Has

In the cable-side electrical connector, in the present invention, the lock lever extends along the side of the housing to form an arm shape having flexibility, and is connected to the mating connector from the supported end supported by the housing. And a horizontal arm portion extending in a horizontal direction perpendicular to the connector fitting direction, and a vertical arm portion extending in the vertical direction by redirecting from the horizontal arm portion in the connector fitting direction. The lock part which engages with a mating connector is formed in the free end side of an arm part, and a junction part of a horizontal arm part and a vertical arm part, or a horizontal arm part, or the said junction part or a longitudinal direction is formed. The extended portion extending from the arm portion to the opposite side to the supported end portion is provided with a pressurized portion which is pressed and displaced toward the unlocking position. A and it characterized.

According to the present invention having such a configuration, the lock lever has a horizontal arm portion and a vertical arm portion extending from the horizontal arm portion. When the locking lever is engaged with the mating connector, the lock lever is bent at the horizontal arm portion and further at its end. Vertical arm part rose At the position of the lock portion formed on the free end side of the vertical arm portion, the warp of the transverse arm portion and the warp of the vertical arm portion are displaced by an overlapping amount, so that the displacement in the lock portion is large and the amount of displacement for the lock portion is sufficiently secured. In the connector requiring height reduction, the vertical arm portion is short, but the length of the horizontal arm portion can be relatively large. For example, when the mating connector is attached to the circuit board and the connector of the present invention is fitted to the mating connector in a direction perpendicular to the circuit board, the connector of the present invention is relatively in the direction parallel to the surface of the circuit board. There is a margin of dimension, and the horizontal arm part extending in this direction can also be lengthened. As a result, since the curvature of both arm parts overlaps, the displacement in the said lock part can fully be ensured.

In the connector of the present invention, unlocking is performed by bending the lock lever by pressing the pressurized portion as if the connector is pinched.

In the present invention, the lock lever can be formed by integral molding with the housing. This reduces the number of parts because there is no need to make the lock lever separately. However, it is also possible, of course, to make the lock lever separately from a metal plate or the like and attach it to the housing as necessary.

In the present invention, as an embodiment, the lock portion is a lock claw projecting to the opposite side with respect to the side of the housing, and the pressurized portion is formed on the side opposite to the side of the housing and pushed toward the side. We can do wealth.

In the present invention, the housing preferably has a metal shell for shielding attached to an outer surface thereof, and a part of the metal shell is disposed close to the lock lever in an outer position where the side of the housing is opposite to the side surface of the housing. have. In this way, the connector is covered with a metal shell to have shielding properties. In addition, since the lock lever is protected from the outside by a part of the metal shell, even if the lock lever is unexpectedly subjected to a large force in the outward direction, the displacement is regulated by the part of the metal shell. Moreover, since the housing side surface is located in the inner direction, the housing is originally regulated by the side surface in that direction.

It is desired that a part of the metal shell be disposed in an outer position with respect to a part of the longitudinal arm portion of the lock lever. Even if a part of the metal shell is located outside the longitudinal arm portion of the lock lever, the lock lever is sufficiently protected. The reason for this is that in the range where the lock lever extends, the vertical arm portion is displaced the largest, so that if the displacement is restricted by the vertical arm portion, it is sufficiently protected.

In the present invention, when the lock lever has a lock hook projecting on the opposite side to the side of the housing as the lock portion, a part of the metal shell disposed close to the lock lever in the outer position on the opposite side to the side of the housing is It is preferable that it is formed in the protrusion range of the said lock hook. In this way, the width dimension between both sides as a whole connector does not become large by forming a metal shell.

In the present invention, the metal shell may have an upper surface portion covering the upper surface opposite to the fitting side to the mating connector, and the upper surface portion may also cover the upper surface side of at least a part of the lock lever. By doing so, even when an unexpected force is applied upward, the lock lever is restricted and protected in that direction.

As described above, in the present invention, since the lock lever having the lock portion at the tip side has the horizontal arm portion and the vertical arm portion, the horizontal direction, for example, the mating connector is attached to the circuit board without any limitation in the dimensions of the connector. When the connector of the present invention is fitted with the mating connector in a direction perpendicular to the circuit board, the horizontal arm portion can be made sufficiently long in the direction parallel to the surface of the circuit board, so that the height dimension of the connector is small and the vertical length is increased. Even if the arm portion is short, the total length of the lock lever is long, and the displacement amount of the lock portion at the time of locking is largely secured, thereby making the lock easy and reliable. In addition, since the lock lever can be molded integrally with the housing, it is not necessary to form a separate member and the number of parts does not increase.

The problem of large connector size does not occur.

The connector of this embodiment of this structure is assembled and used by the following points.

<Assembly point>

First, a cable such as the flat cable F is connected to the housing 11 to which the terminal 20 is attached, as indicated by the double-dotted line in FIG. 5. Each cable of the flat cable (F) is exposed by a core wire (core wire) at their ends, and is connected by the horizontal portion 21, which is the connection portion of the corresponding terminal 20 by soldering. The flat cable F has a ground portion F1 at a position ahead of the exposed core wire, and the ground portion F1 is in contact with the elastic tongue 41D of the lower shell 40 after the lower shell is attached. As a result, conduction is made with the lower shell 40. This flat cable extends forwardly through the space between the upper shell 30 and the extension part 15 of the housing 11. Next, after connecting the flat cable F, the upper shell 30 is attached from above. The engaging hole 33A of the front plate part 33 of the upper shell 30 and the engaging hole 32B-1 of the rear plate part 32 are connected to the corresponding engaging hook 18A and the engaging hook 16A of the housing 11. Each hangs, the upper shell 30 is fixed to the housing 11.

Next, the lower shell 40 is attached to the housing 11 to which the upper shell 30 is attached. The engaging hole 43A of the front plate part 43 of the lower shell 40 and the engaging hole 42B-1 of the rear plate part 42 are each caught by the corresponding engaging hook 18B of the housing and a notching hook, not shown, respectively. The lower shell 40 is fixed to the housing 11. At this time, the front plate portion 43 of the lower shell 40 is located inside the front plate portion 33 of the upper shell 30 and a part overlaps and is in contact with each other, the rear plate portion of the lower shell 40 42 is located inside the side plate part 34 of the upper shell 30, and a part overlaps and is in contact with each other. In addition, at the time of assembling the lower shell 40, the rear portion 44B of the side plate portion 44 of the lower shell 40 passes over the lock hook 13C-1 of the lock lever 13 and the lock lever ( 13) is located in contact with the upper portion. At that time, the pressing portion 13D of the lock lever 13 is pressed to displace the lock hook 13C-1 toward the side surface of the housing so that the rear portion 44B is connected to the lock hook 13C-1. It is preferable that the lower shell 40 can be easily assembled so as not to interfere.

In this way, the upper shell 30 and the lower shell to the housing 11 to which the terminal 20 is attached are attached to obtain the connector of the present embodiment.

<Use point>

(1) With respect to the mating connector 60 attached to a circuit board (not shown), the connector 10 of this embodiment is fitted from the upper direction, ie, at right angles with respect to the circuit board, as shown in FIG. . Although the fitting portion 12 of the connector 10 enters the receiving recess of the mating connector 60, the fitting is made, but in the fitting process, the lower end of the lock lever 13 of the connector 10 is fitted. The lock claw 13C-1 formed to protrude laterally is subjected to a pressing force from the mating connector and elastically displaces toward the side surface of the housing 11. This elastic displacement is easily obtained by overlapping the elastic deflections of the horizontal arm portion 13B and the vertical arm portion 13C of the lock lever 13. In this way, when the fitting progresses to a predetermined position, the pressing force from the mating connector is released, locking with the corresponding locking portion is performed, and the connector is prevented from being reliably removed.

(2) Next, when pulling out the connector 10 from the mating connector 60, the side surface of the to-be-pressed part 13D which is a pushbutton part of both lock levers 13 is close to the side surface of the housing 11. Press in the direction of loss, and pick up the connector with your fingers. When the to-be-pressed portion 13D is pressed in the direction of the housing side surface, the horizontal arm portion 13B causes elastic bending in that direction, and therefore, the vertical arm portion 13C is the amount of displacement at the rear end of the horizontal arm portion 13B. Displace by the same amount. As a result, the lock hook 13C-1 at the lower end of the vertical arm portion 13C is pulled out of the corresponding lock portion of the mating connector, and the connector 10 can be pulled out upward.

(3) The lock lever 13 may receive an external force in addition to the normal direction when handling the connector 10, especially in a state before fitting to the mating connector. For example, in FIG. 2, the lock lever 13 may receive an unexpected force in the arrow B direction or the upward direction away from the side surface of the housing 11, and conventionally there is no stopper in these directions. The lock lever was even deformed and broken depending on the magnitude of the external force. In this embodiment, all 44A of the side plate parts 44 of the lower shell 40 which are firmly attached to the housing 11 are the outer side of the horizontal arm part 13B of the lock lever 13, and the rear part ( Since 44B faces the upper outer surface of the vertical arm portion 13C in close proximity, even if the lock lever 13 is unexpectedly forced outward, all of the side plate portion 44A and the rear portion 44A 44B functions as a stopper to prevent deformation in the same direction of the lock lever 13. In addition, since the lateral edge of the upper plate part 31 of the upper shell 30 covers a part of the upper surface of the lock lever 13, even if the lock lever 13 is unexpectedly forced upward, the upper plate part 31 By the lateral edges, deformation upward of the lock lever 13 is prevented.

Thus, in the present invention, the lock lever can secure a large amount of elastic displacement in the lock portion of the vertical arm portion by the horizontal arm portion that can be set relatively long even if the vertical arm portion is short. Even if the connector is long and requires a height reduction, it can be locked easily and reliably.

The present invention is not limited to the illustrated embodiment, and various modifications are possible. For example, the lock portion formed in the lock lever is not a protruding lock hook, but a mating connector has a protruding portion, and may be formed as a hole portion or a groove portion caught therein. The extended portion in which the pressurized portion for unlocking may be formed may extend from the vertical arm portion without extending from the junction of the horizontal arm portion and the vertical arm portion, and the pressurized portion may not be formed in the extension portion. It may be formed without being located at the horizontal arm portion or the junction portion.
