Problems solved by technology

However, in the configuration in which the cable is held only by the clamp, the bonding force between the cable and the sealing resin portion that seals the inner space of the housing cannot be ensured sufficiently, and peeling occurs at the connection portion, resulting in poor environmental resistance.

Embodiment approach 1

[0089] figure 1 It is a perspective view of the proximity sensor in Embodiment 1 of the present invention, figure 2 is along figure 1 Sectional view of line II-II shown in . in addition, image 3 yes figure 2 An enlarged cross-sectional view of region III shown in, Figure 4 yes figure 1 A schematic perspective view of the cable shown in and the splice spacer fixed thereto. First, refer to the Figure 1 ~ Figure 4 , the configuration of the proximity sensor 1A in this embodiment will be described.

[0090] Such as figure 1 and figure 2 As shown, the proximity sensor 1A as an electronic device in this embodiment has a substantially cylindrical outer shape, and includes: a housing 10, a detection part assembly 20 including a first sealing resin part 26, a cable 30, a joint spacer member 40, The jig 50 and the second sealing resin part 60 .

[0091] The casing 10 includes a metal elongated cylindrical member with both ends opened, and has a front end and a rear end ...

Embodiment approach 2

[0181] Figure 15 And FIG. 16(A) and FIG. 16(B) are a flowchart and an assembly diagram for explaining the manufacturing method of the proximity sensor in Embodiment 2 of this invention, respectively. Below, refer to Figure 15 16(A) and 16(B) describe the method of manufacturing the proximity sensor in this embodiment.

[0182] Furthermore, as will be described later, the method of manufacturing the proximity sensor in this embodiment is slightly different from the method of manufacturing the proximity sensor 1A in the first embodiment, and accordingly, its shape is also slightly different. It is roughly clear in the assembly diagrams of FIG. 16(A) and FIG. 16(B), so its illustration is omitted here.

[0183] First, if Figure 15 As shown, make joint spacer member 40 (step ST21), next, joint spacer member 40 is installed on the cable 30 (step ST22), then, joint spacer member 40 is welded on the cable 30 (step ST23), Next, the cable 30 is connected to the probe assembly 20...

Abstract

The invention provides an electronic machine with an excellent environment resistance; the electronic machine comprises a housing, a cable pulled out from the housing, a joint isolation member arranged on the cable and made from a resin, a cylindrical clamp holding the cable, and a sealing resin portion that fills the inner space defined by the housing and the clamp; the cable has a core wire anda sheath covering the core wire and made from the resin; the core wire is not covered by the sheath in the cable end and exposed; the joint isolation member has a cylindrical base portion that coversthe outer periphery of the sheath, and a cylindrical protruding portion that protrudes to the front end of the cable. The inner and outer peripheries of the protruding portion and the front end face of the protruding portion in the axial direction are respectively covered by the sealing resin portion.

Description

technical field [0001] The present invention relates to an electronic device, and more particularly, to an electronic device in which a space inside a case is sealed with resin, and a cable is pulled out from the inside of the case. Background technique [0002] In a specific electronic device, in order to ensure the environment resistance, the space inside the case housing the electronic components is sealed with resin. In this case, how to pull out a power supply cable for supplying electric power, a signal cable for connecting to an external terminal, and the like from the inside of the housing while ensuring environmental resistance becomes a problem. [0003] Generally, cables such as the power supply cable and signal cable are held by elastically deformable clips fitted in openings provided in the case, thereby relieving stress applied to the cables. However, in a configuration in which the cable is held only by clips, the bonding force between the cable and the seali...
