The connector device 1 of the present invention includes a connector 10 and a cap 20, and the connector 10 has at least a contact 14 and a housing 12.

  Before describing the connector device 1 of the present embodiment, first, a connection object will be described. Examples of the connection object include a mating connector (a cable connected or mounted on a board), a card, and the like. In this embodiment, the connector device corresponds to the mating connector.

  First, the cap 20 which is the point of the present invention will be described. The cap 20 is an electrically insulating plastic and is manufactured by a known technique of injection molding. This material is appropriately selected in consideration of dimensional stability, workability, flexibility, cost, etc. Can include polybutylene terephthalate (PBT), polyamide (66PA, 46PA), polycarbonate (PC), and synthetic materials thereof.

  The cap 20 is used for adsorbing at the time of reflow for automatic mounting, and for increasing dustproofness to the fitting port 18. The cap 20 mainly has a main body 22 and projecting pieces 24 projecting in one direction from both sides in the width direction of the main body 22. Since the main body 22 is a portion that is adsorbed during reflow, the main body 22 has a substantially plate shape, and the opposite surface of the protruding piece 24 is flat. The size of the main body 22 may be any size as long as it can be adsorbed by an automatic machine, but is appropriately designed in consideration of the size of the connector, the difference in the number of cores, workability, strength, and the like.

  An engaging portion 28 protruding to one side is provided at the free end of the protruding piece 24. In this embodiment, since the fitting portion 18 is mounted inside, the engaging portion 28 protrudes outward. That is, when mounting on the outside of the fitting port 18, the engaging portion 28 protrudes inward. The shape and size of the protruding piece 24 and the engaging portion 28 may be anything as long as they can be engaged with the fitting port 18 of the housing 12 and do not drop off when adsorbed. And design appropriately considering the handling of differences in the number of cores. Although the shape of the engaging portion 28 is a trapezoid in this embodiment, a triangle or a square is conceivable.

In this embodiment, the width is 1.0 mm.

The divided engaging portions 28 of the protruding pieces 24 are arranged so that their positions are shifted. By disposing the engagement portion 28 so as to be displaced, at least one engagement portion 28 corresponds to a change (warping or falling down due to heat) of the fitting port 18 of the housing 12 before and after reflow mounting. It engages with the side wall 30 of the housing 12 before and after reflow. As a method of shifting the position of the engaging portion 28, there are an inclination (taper) as shown in FIG. 5 (A) and a step as shown in FIG. 5 (C). Considering the change of the fitting port 18 of the housing 12 before and after reflow mounting (warping, collapse or swelling due to heat), the position of the divided engagement portion 28 should be about 0.5 to 1.5 mm. desirable.
By shifting the position as described above, even if the engaging portion 28 that is initially engaged changes (deforms) in the same manner as the housing 12 due to heat during reflow, the other engagement that is not initially engaged is changed. Since the joining portion 28 does not change (deform), the other engaging portion 28 is engaged as shown in FIG.

The type and size of the connecting portion 40 are appropriately designed in consideration of the board occupation area, workability, strength, stable connection, and the like.

  The fixing portion 38 is a portion held by the housing 12 and is fixed by press-fitting, hooking (lance), welding, or the like. In this embodiment, the fixing portion 38 is fixed by press-fitting, and the fixing portion 38 is provided near the center between the contact portion 36 and the connecting portion 40. The position and size of the fixing portion 38 are appropriately designed in consideration of stable contact and holding force.

It is designed to deviate by ~ 1.5 mm.
As described above, only one slit 26 is provided, but a plurality of slits 26 may be provided as long as the role is satisfied. However, the design is made in consideration of the miniaturization of the connector.

  As an application example of the present invention, it is used in a connector device 1 used in electrical equipment and electronic equipment such as a sequencer, an inverter, a car navigation system, etc. In particular, even if warping occurs in an insulator or cap after reflow, It is about a structure that does not fall off or fall (comment: is this expression OK?).

Claims (10)

A cap that is held in the mating port of the connector,
In a cap comprising a main body and a projecting piece that protrudes in one direction from both sides in the width direction of the main body and has an engaging portion that protrudes to one side at the free end side,
The projecting piece is provided with at least one slit so that the engaging portion has a predetermined interval,
A cap characterized in that at least two or more engaging portions of the protruding pieces divided by the slit are arranged so as to shift positions. So that the engaging part of the protruding piece protrudes outward,
The projecting piece is provided with at least one slit so that the engaging portion has a predetermined interval,
The cap according to claim 1, wherein the engaging portions of at least two or more protruding pieces divided by the slits are arranged so as to shift positions. 3. The cap according to claim 1, wherein after reflow, even if the side wall of the housing is deformed by heat, at least one pair of opposing engaging portions engage with the side wall of the housing. 4. The cap according to claim 1, wherein the engaging portion is shifted by 0.5 to 1.5 mm. The cap according to claim 1, wherein the engaging portion is a convex portion. A connector comprising a plurality of contacts and a housing that holds and arranges the contacts and has at least two side walls, and that forms a fitting port through which the mating connector is inserted and removed by the side walls,
The fitting port is reflowed with a cap provided with a main body and a protruding piece that protrudes in one direction from both sides in the width direction of the main body and has an engaging portion that protrudes to one side at the free end. In the connector device,
The projecting piece is provided with at least one slit so that the engaging portion has a predetermined interval,
The engaging portions of at least two or more of the protruding pieces divided by the slit are arranged so as to shift the positions,
The connector device reflows in a state where the engaging portion is engaged with a side wall of the housing. So that the engaging part of the protruding piece protrudes outward,
The projecting piece is provided with at least one slit so that the engaging portion has a predetermined interval,
The connector device according to claim 6, wherein the engaging portions of the at least two projecting pieces divided by the slit are arranged so as to shift positions. 8. The connector device according to claim 6, wherein after reflow, even if the side wall of the housing is deformed by heat, at least one pair of opposing engaging portions engage with the side wall of the housing. The connector device according to claim 6, wherein the engaging portion is shifted by 0.5 to 1.5 mm. The connector device according to claim 6, wherein the engaging portion is a convex portion.
