  In a display device such as a liquid crystal television, a speaker requires a relatively large amount of electric power. Therefore, a speaker conductor is formed with a diameter larger than that of other conductors, and is connected to the conductor. These connectors are also formed larger than other connectors.

  However, display devices such as liquid crystal televisions in recent years tend to be increasingly narrowed and thinned, and accordingly, a wiring space for large-diameter conductors for speakers arranged around the periphery of the display unit and Since the arrangement space for a large-sized connector for relay is also narrowed, it is difficult to fix the conductor and fix the connector in this narrow space, and an improvement measure has been demanded.

  In addition, in the structure in which the conductive wire is fixed with the adhesive tape, the connector itself is not fixed, so that the connector is likely to slightly vibrate during operation of the speaker. Further, in the structure in which the connector itself is fixed by the holder, the number of parts is increased and it is difficult to secure a mounting space for the holder, and it is difficult to fix the connector by the holder.

It is possible to hold the connector stably and strongly. Therefore, a dedicated connector fixing component is not required, and the connector can be easily held and fixed by performing the fitting operation without increasing the number of components. In addition, a relatively large relay connector has a large variation in the outer surface portion, and the connector having a large variation can be held stably and strongly. Also, since the position of the connector relative to the rib can be shifted in the longitudinal direction of the conductor, the length of the conductor connected to the connector varies, and the connector is stable and strong even when the location of the connector is not constant. Can be held.

Embodiment 4
16 and 17 are a perspective view and a plan view showing another configuration of the connector holding structure A. FIG. 18, 19, and 20 are a perspective view, a plan view, and a front view showing a configuration in a state where the connector 2 and the cables 9, 9,. 18 and 19 correspond to FIGS. 16 and 17.
Here, the cables 9, 9,... Are a plurality of conductors different from the conductors 1, 1 connected to the connector 2.
The connector holding structure A in the present embodiment has a configuration different from the connector holding structure A shown in the first to third embodiments, but has a function of holding the connector 2 similarly to these.

Further, the connector holding structure A in the present embodiment fixes the cables 9, 9,. However, even if no cable 9, 9,... Is fixed to the connector holding structure A, the function of holding the connector 2 of the connector holding structure A is not hindered. On the other hand, when the connector 2 is not held by the connector holding structure A, the cables 9, 9,... Cannot be fixed by the connector holding structure A. The number of cables 9 to be fixed by the connector holding structure A may be one.
Hereinafter, differences from the first to third embodiments will be described, and other parts corresponding to the first to third embodiments will be denoted by the same reference numerals and description thereof will be omitted.

First, the configuration of the connector holding structure A in the present embodiment will be described.
The connector holding structure A shown in FIGS. 16 to 20 holds the connector 2 connecting the two conducting wires 1 and 1 to the resin molded product 3 facing the conducting wires 1 and 1. The resin molded product 3 is provided with two ribs 8 and 8 which are opposed to each other in a direction perpendicular to the longitudinal direction of the conducting wire 1. The front cabinet 15 constitutes the resin molded product 3.

Hereinafter, the surface having the ribs 8, 8 of the resin molded product 3 is referred to as a rib forming surface 30. Further, the height direction of the rib 8 (that is, the protruding direction of the rib 8), the longitudinal direction of the conducting wire 1, and the direction orthogonal to the longitudinal direction of the conducting wire 1 (more specifically, orthogonal to the longitudinal direction of the conducting wire 1, And the direction along the rib forming surface 30) is referred to as the up-down direction, the front-rear direction, and the left-right direction.
Each rib 8 has a rectangular plate-shaped rib body 80 along the front-rear direction. Below, the mutually opposing surface (or separating surface) of the rib bodies 80, 80 is referred to as an opposing surface (or separating surface).

The rib main body 80 includes a clamping piece 81 for clamping the connector 2 from the top to the center in the vertical direction. The clamping piece 81 has flexibility. The opposing surfaces of the sandwiching pieces 81 and 81 are in contact with the outer surface (specifically, the left and right surfaces) of the connector 2 as will be described later.
A locking claw 82 that locks to the connector 2 is protruded from the top of the rib main body 80 as will be described later. The projecting position of the locking claw 82 is the central portion in the front-rear direction on the opposing surface of the rib main body 80. The locking claw 82 has a tapered surface so that the protruding amount gradually increases from the top side to the base side of the rib main body 80.

As will be described later, abutting portions 83 and 83 that abut against the connector 2 protrude from the center portion of the rib body 80 in the vertical direction. The projecting positions of the contact portions 83, 83 are both ends in the front-rear direction on the facing surface of the rib main body 80.
A reinforcing portion 85 that reinforces the rib main body 80 is provided so as to protrude from the center in the vertical direction to the base of the separation surface of the rib main body 80. The reinforcing portion 85 is not provided on the separation surface of the holding piece 81. Therefore, the reinforcing portion 85 does not impair the flexibility of the sandwiching piece 81.

The opposing surfaces of the rib bodies 80, 80, and thus the opposing surfaces of the clamping pieces 81, 81, are separated by an appropriate length in the left-right direction so as to be equal to or slightly shorter than the dimensions of the connector 2 to be clamped. doing. As a result, the connector 2 can be easily and strongly held between the opposing surfaces of the holding pieces 81 and 81.
The locking claws 82 and 82 are separated from each other by an appropriate length in the left-right direction so as to be shorter than the dimension of the connector 2 to be clamped. As a result, when the sandwiching pieces 81, 81 are bent in a direction away from each other, the connector 2 can easily pass between the locking claws 82, 82, and the sandwiching pieces 81, 81 are not bent. In addition, the connector 2 cannot pass between the locking claws 82.

The abutting portions 83, 83 provided on one rib main body 80 and the abutting portions 83, 83 provided on the other rib main body 80 are spaced apart from each other by an appropriate length. The separation distance and the height from the rib forming surface 30 to each contact portion 83 are designed according to the number of cables 9, 9,... To be fixed by the connector holding structure A and the outer diameter.
The locking claw 82 and the contact portion 83 of each rib main body 80 are separated by an appropriate length in the vertical direction. As a result, the connector 2 held between the locking claw 82 and the contact portions 83 and 83 is prevented from unnecessarily shaking in the vertical direction.

  When there is a variation in the dimensions of the connector 2 to be held by the connector holding structure A, the designer of the connector holding structure A determines the dimensions of each part of the connector holding structure A as representative of the dimensions of the plurality of connectors 2, 2,. What is necessary is just to design according to a value (for example, average value or mode value etc.).

Next, the holding of the connector 2 by the connector holding structure A in the present embodiment will be described.
The connector 2 has a rib body in a posture in which the bottom surface of the connector 2 (that is, one of the two surfaces along the longitudinal direction of the conducting wire 1 and not provided with the convex portion 23) faces the rib forming surface 30. The ribs 80 and 80 are inserted between the rib bodies 80 and 80 from the top side toward the base side. At this time, if the protrusions 23 and 23 of the connector 2 are slid along the front and rear end surfaces of the rib bodies 80 and 80, the connector 2 is easily positioned in the front and rear direction.

  When the connector 2 inserted between the rib bodies 80, 80 abuts against the taper surfaces of the locking claws 82, 82, the connector 2 further slides on the taper surfaces of the locking claws 82, 82 and further the rib bodies 80, 82. Move to 80 base side. At this time, since an external force is applied from the connector 2 to the locking claws 82, 82 in a direction that pushes the gap between the clamping pieces 81, 81, the clamping pieces 81, 81 bend in a direction away from each other. With the bending of the clamping pieces 81, 81, the locking claws 82, 82 are further separated from each other.

  When the bottom surface of the connector 2 inserted between the rib bodies 80, 80 comes into contact with the four contact portions 83,..., 83, the movement of the connector 2 is completed. At this time, since the connector 2 is positioned on the base side with respect to the locking claws 82 and 82, the external force from the connector 2 to the locking claws 82 and 82 is lost. Therefore, the shape of the clamping pieces 81 and 81 is restored from the bent state by the elastic restoring force of the clamping pieces 81 and 81. Accordingly, the sandwiching pieces 81, 81 sandwich the connector 2 in a state where the opposing surfaces of the sandwiching pieces 81, 81 are in contact with both the left and right sides of the connector 2. Further, the locking claws 82 and 82 are locked to the top surface of the connector 2.

The horizontal movement of the connector 2 held by the connector holding structure A is regulated by the sandwiching pieces 81 and 81. Further, the vertical swing of the connector 2 is restricted by the locking claws 82, 82 and the contact portions 83,. The fluctuation of the connector 2 in the front-rear direction is suppressed by the frictional resistance between the connector 2 and the rib main body 80.
The position of the connector 2 in the front-rear direction can be adjusted in a range where the convex portions 23, 23 are not located between the rib bodies 80, 80.

  As described above, the ribs 8 and 8 are separated from each other by an appropriate length. Moreover, nothing other than the connector holding structure A is provided between the rib bodies 80 of the resin molded product 3. Therefore, even if the connector 2 is held by the connector holding structure A, the gap 84 exists between the base portions of the rib main bodies 80 and 80.

Next, fixing of the cables 9, 9,... By the connector holding structure A in the present embodiment will be described.
First, before the connector 2 is held by the connector holding structure A, the cables 9, 9,... Are inserted between the rib bodies 80, 80. At this time, the simplest insertion procedure is to insert the cables 9, 9,... Halfway from the top side of the rib bodies 80, 80 toward the base side.
Next, the connector 2 is held by the connector holding structure A by the procedure as described above. As a result, the cables 9, 9,... Are inserted between the connector 2 held by the connector holding structure A and the rib forming surface 30, that is, through the gap 84.

  The lateral movement of the cables 9, 9,... Inserted through the gap 84 is restricted by the sandwiching pieces 81, 81. Further, the vertical movement of the cables 9, 9,... Is restricted by the connector 2 and the rib forming surface 30. Even if a large external force is applied from the base side to the top side of the rib main bodies 80, 80 so that the cables 9, 9,... Are removed from the gap 84, the ribs 80, 80 are locked by the locking claws 82, 82. The connector 2 is not dropped from the connector holding structure A, so that the cables 9, 9,.

  The fixing of the cables 9, 9,... By the connector holding structure A is not limited to the procedure performed before the connector 2 is held by the connector holding structure A. For example, after the connector 2 is held by the connector holding structure A, a procedure of inserting the cables 9, 9,...

Conventionally, the cables 9, 9,... Are fixed with ribs as described in Patent Documents 1 and 2. Therefore, if an external force greater than the frictional resistance force between the ribs is applied to the cables 9, 9,..., The cables 9, 9,.
The connector 2 is a holder for holding the connector, and is fixed separately from the cables 9, 9,.

  On the other hand, if the cables 9, 9,... Are fixed with the connector holding structure A, the material of the resin molded product 3 is reduced by the amount that the ribs described in Patent Documents 1 and 2 are unnecessary, The molded product 3 can be reduced in size and weight. Reduction in size and weight of the resin molded product 3 can contribute to narrowing, thinning, and weight reduction of the display device. Further, the connector holding structure A is integrally formed on the resin molded product 3 rather than a mold in which the connector holding structure A and the ribs described in Patent Documents 1 and 2 are integrally formed on the resin molded product 3. Such a mold reduces the mold manufacturing cost.

Further, since the fixing position of the connector 2 and the fixing position of the cables 9, 9,... Can be concentrated in one place, the working efficiency can be improved as compared with the case where these are dispersed.
Further, the cables 9, 9,... Are prevented from falling off the connector holding structure A.
