The first surface (lower surface) of the pair of first walls 11 in the third direction and the first surface of the pair of second walls 12 in the third direction, that is, the first surface of the main portion 10 in the third direction are first mounted. It is a surface 13. Further, the second surface (upper surface) of the pair of first walls 11 in the third direction and the second surface of the pair of second walls 12 in the third direction, that is, the second surface of the main portion 10 in the third direction are second. 2 Mounting surface 14.

The first mounting surface 13 comes into contact with the first substrate 4 in a state where the connector 2 and the other connector 3 (see FIG. 3) are connected to each other. In other words, the first mounting surface 13 comes into contact with the first substrate 4 with the main portion 10 sandwiched between the two substrates 4 and 5. The second mounting surface 14 comes into contact with the second substrate 5 in a state where the connector 2 and the other connector 3 are connected to each other. In other words, the second mounting surface 14 comes into contact with the second substrate 5 with the main portion 10 sandwiched between the two substrates 4 and 5. In this embodiment, the pair of mounting surfaces 13 and 14 are all flat. That is, at least one of the pair of mounting surfaces 13 and 14 (here, both sides) is flat. Therefore, the first mounting surface 13 and the second mounting surface 14 come into contact with the first board 4 and the second board 5, respectively, in a state where the connector 2 and the other connector 3 are connected to each other.

The portion surrounded by the pair of first walls 11 and the pair of second walls 12 is the opening 15. That is, the opening 15 penetrates the main portion 10 in the third direction (vertical direction) so as to connect the pair of mounting surfaces 13 and 14. The opening 15 has a rectangular shape that is long in the first direction (front-back direction) in a plan view. The size of the opening 15 is a size in which the connector 2 and the other connector 3 can be accommodated.

The main portion 10 has a plurality of (here, four) protrusions 17 having a semicircular columnar shape. Each of the plurality of protrusions 17 projects from the inner peripheral surface of the opening 15 toward the inside of the opening 15. In the present embodiment, two of the four protrusions 17 are oriented (to the left) from the first surface (right surface) to the second surface (left surface) in the second direction of the inner peripheral surface of the opening 15. It stands out. Further, the remaining two protrusions 17 project in a direction (to the right) from the second surface in the second direction to the first surface of the inner peripheral surface of the opening 15.

It protrudes from each of the. The two protrusions 17 protruding from the first surface of the opening 15 in the second direction and the two protrusions 17 protruding from the second surface of the opening 15 in the second direction face each other in the second direction (left-right direction). is doing.

Here, the plurality of protrusions 17 are all in contact with the side surface of the connector 2. Therefore, when an external force acts on the connector 2, the movement of the connector 2 is hindered by the frictional force (static frictional force) generated by the plurality of protrusions 17 coming into contact with the side surface of the connector 2. That is, the plurality of protrusions 17 (holding structure 16) are configured to generate frictional force with the side surface of the connector 2 by coming into contact with the side surface of the connector 2. In other words, the plurality of protrusions 17 (holding structure 16) hold the main portion 10 in the connector 2 by the frictional force with respect to the connector 2.

The main portion 10 further has an expansion portion 18. The expansion portion 18 is provided on at least one of the pair of mounting surfaces 13, 14 on the peripheral edge of the opening 15, and is recessed in a direction away from the one mounting surface 13, 14.

(3) Mounting Structure of Protective Member The mounting structure of the protective member 1 will be described below with reference to FIGS. 1 to 4B. As shown in FIG. 4B, the mounting structure of the protective member 1 includes a protective member 1, a connector 2, another connector 3, and two boards 4 and 5. The main portion 10 of the protective member 1 is attached to the connector 2. The connector 2 is connected to the other connector 3. A connector 2 and another connector 3 are mounted on the two boards 4 and 5, respectively. The main portion 10 of the protective member 1 is attached to the connector 2 in a state of being sandwiched between the two substrates 4 and 5.

Here, a method of assembling the mounting structure of the protective member 1 will be described. First, the main portion 10 of the protective member 1 is pushed against the connector 2 so that the connector 2 is located inside the opening 15. As a result, as shown in FIGS. 1 to 2B, the main portion 10 of the protective member 1 is held by the connector 2 by contacting the side surface of the connector 2 with the plurality of protrusions 17 (holding structures) bent. .. That is, the main portion 10 of the protective member 1 is attached to the connector 2. Here, as shown in FIG. 2B, in the present embodiment, in the third direction (vertical direction, that is, the direction in which the pair of mounting surfaces 13 and 14 are lined up), the length L1 of the main portion 10 is the length of the connector 2. It is longer than L2. In other words, the thickness dimension of the main portion 10 is larger than the thickness dimension of the connector 2.

Next, the other connector 3 is connected to the connector 2 by fitting the fitting recess 33 of the other connector 3 into the base portion 23 of the connector 2. Specifically, the fitting recess 33 is fitted to the base 23 by pushing the second substrate 5 toward the first substrate 4 so that the fitting recess 33 is aligned with the base 23 in a plan view. .. Here, in the present embodiment, when the contact 32 of the other connector 3 first contacts the contact 22 of the connector 2, the main portion 10 of the protective member 1 does not contact the second substrate 5 (see FIG. 4A). That is, in the third direction (vertical direction, that is, the direction in which the pair of mounting surfaces 13 and 14 are lined up), the length L1 of the main portion 10 is such that the connector 2 and the other connector 3 are not connected to each other and the connector 2 is used. The maximum length L3 of the connector 2 and the other connector 3 in the state where the contact 22 of the connector 22 and the contact 32 of the other connector 3 are in contact with each other is shorter. In other words, the length L1 of the main portion 10 is shorter than the maximum distance from the upper surface of the first substrate 4 to the lower surface of the second substrate 5 when the contacts 22 and 32 are in contact with each other.

By further pushing the second substrate 5 toward the first substrate 4 from the state shown in FIG. 4A, the main portion 10 of the protective member 1 is pushed by the second substrate 5 and bends. As a result, the main portion 10 of the protective member 1 is sandwiched between the two substrates 4 and 5 in a bent state. Then, the connector 2 is connected to the other connector 3 by fitting the base portion 23 into the fitting recess 33 in a state where the main portion 10 of the protective member 1 is bent. Here, in the present embodiment, the main portion 10 is a force required for the elastic force acting on the two substrates 4 and 5 from the main portion 10 to release the state in which the connector 2 and the other connector 3 are connected to each other. It is configured to be smaller than (hereinafter referred to as "fitting force"). Therefore, the state in which the main portion 10 of the protective member 1 is sandwiched between the two substrates 4 and 5 (see FIG. 4B) is maintained even if the external force for pushing the second substrate 5 toward the first substrate 4 is lost. To.

Specifically, parameters such as the thickness dimension (third direction (vertical direction) dimension), the compressibility, and the hardness of the main portion 10 are set so that the elastic force becomes smaller than the fitting force. As an example, the main portion 10 has a thickness dimension of about 3.5 mm before a constant force is applied, and the thickness dimension of the main portion 10 after a constant force is applied. It has a compression ratio of about 3.0 mm. Further, as an example, the main portion 10 has a hardness of about 3 to 30 degrees. Of course, the compressibility and hardness are merely examples, and the purpose is not limited to the main portion 10 having these compressibility and hardness.

(4) Advantages The protective member 1 of the present embodiment is sandwiched between two boards 4 and 5, and is a connector 2 including connection parts 221, 321 and other connectors by the two boards 4 and 5 and the main part 10. 3 is surrounded so as to be separated from the outside of the protective member 1.

Further, for example, when sealing between two substrates 4 and 5 with a sealing material made of epoxy resin, in the protective member 1 of the present embodiment, the sealing material invades the space where the connector 2 and the other connector 3 are located. It also has the advantage of being easy to block.

In addition, the protective member 1 of the present embodiment has an advantage that it can be replaced with a new one even if it deteriorates over time.

(5) Modification example The following is a list of modification examples of this embodiment. Since the basic configurations of the modifications described below are the same as those of the protective member 1 of the present embodiment, the description of the common points will be omitted. Further, the modifications described below can be applied in combination as appropriate. For example, the third modification can be combined with either the first modification or the second modification. Further, for example, the third modification can be combined with any one of the second embodiment, the first modification to the fifth modification of the second embodiment, and the third modification to be described later.

(5.1) First Modified Example In the protective member 1 of the first modified example, as shown in FIGS. 5 and 6, the main portion 10 is in a third direction (up and down) in addition to the expansion portion 18 of the first embodiment. At the second end (lower end) of the direction), the extension 18 is further provided over the entire circumference of the peripheral edge of the opening 15. Further, in this modification, the expansion portion 18 has a taper 181.

The taper 181 is inclined so as to widen the opening area of the opening 15 from the first end (upper end) to the second end (lower end) of the main portion 10 in the third direction. In other words, the taper 181 is inclined so as to narrow the opening area of the opening 15 as the distance from the connecting portion 221 (or the mounting surface 13) of the connector 2 increases.
