Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sleeve for electrical terminals that electrically connects and accommodates male and female terminals that are engaged with each other insulated from the outside in the engaged state.

In the present invention, a female terminal is one in which the electrical contact portion is shaped like a noseptacle, and a male terminal is one in which the electrical contact portion is shaped like a tab.

The female terminal is configured to accommodate and hold the tab-shaped electrical contact portion of the male terminal in its receptacle-shaped electrical contact portion.

An object of the present invention is to facilitate the insertion of the mating male and female terminals into the sleeve body as described above.

An example of the implementation of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a substantially box-shaped sleeve body having flexible properties, and the sleeve body 1 has a terminal accommodating chamber 2 that penetrates in the longitudinal direction. It has a length capable of accommodating the entirety of the male and female terminals connected to each other.

The terminal accommodating chamber 2 has both left and right side surfaces located in the upper and lateral direction in the planar direction of the tab-shaped electrical contact portion accommodated in the portion, and upper and lower surfaces located in a direction perpendicular to the planar direction of the tab-shaped electrical contact portion. are doing.

In the terminal accommodating chamber 2, protrusions 3, 3 are formed that protrude from the lower surface of the terminal accommodating chamber 2, slightly toward the front in the center thereof. ), and has an inclined surface that slopes downward in the same direction.

On the other hand, there are projections 5.5', 5 that protrude from both left and right sides of the upper and lower surfaces slightly toward the rear of the central portion of the terminal storage chamber 2.
”, 5 /// is formed, and the protrusion 5゜5
', 5'', and 5''' widen in the rear direction (to the right in FIG. 2) of the sleeve body 1, and have sloped surfaces that slope downward in the same direction.

In addition, the above-mentioned protrusions 3, 3 and 5, 5Z 5tZ 5
The distance from /// is equal to the longitudinal length of the receptacle-shaped electrical contact portion 6 of the female terminal 7, and is equal to the thickness of the plate bone of the receptacle-shaped electrical contact portion 6 during the protrusion of the protrusions 3, 3.

Furthermore, among the above-mentioned protrusions 5, 5', 5'', and 5''', the terminal accommodating chamber 2 is provided in both left and right directions (in the vertical direction in FIG. 3).
The distance between the protrusions 5, 5', 5/', and 51// is approximately the same as the width of the wire connecting portion 10 connected to the receptacle-like electrical contact portion of the female terminal 7.

Since the sleeve body 1 of the present invention is constructed as described above, when the female terminal 7 is inserted into the terminal accommodating chamber 2 from the rear of the sleeve body 1, the receptacle-shaped electrical contact portion 6 is inserted into the protrusion 5,
Using the respective inclined surfaces of 5′, 5″, and 5″, and while bending the projections 5, 5/, 5//, 5/// and the sleeve body 1, the projections 5, 5/, 5/ ', 5
protrusions 5, 5/, which can be inserted and locked between /l/ and the protrusions 3, 3, and are arranged in parallel on the upper and lower sides of the terminal accommodating chamber 2, respectively;
5//.

By utilizing the gaps provided between the terminals 5" and 5", the female terminal 7 can be placed in the terminal storage chamber 2 in either the up or down direction without considering the up and down direction of the wire connection section 10. It is.

Further, when inserting the tab-shaped contact portion of a male terminal (not shown) inserted and held in the receptacle-shaped electrical contact portion 6 into the terminal accommodating chamber 2, the inclined surfaces of the protrusions 3, 3 can be used as a guide. .

Claims (1)

[Scope of utility model registration request] A wire connecting portion connected to the electrical contact portion is accommodated and locked in the center of a terminal accommodating chamber that is formed to fit the tab-shaped electrical contact portion of the mating terminal or penetrates the receptacle-shaped electrical contact portion in the axial direction. A flexible property in which a wire connection part is housed in the rear part of the terminal housing chamber and is connected to the tab-shaped electrical contact part of the mating terminal that is fitted and gripped by the electrical contact part, and is housed in the front part of the terminal housing chamber. The terminal accommodating chamber of the sleeve body has a terminal accommodating chamber that is located between both left and right side surfaces of the tab-shaped electrical contact portion housed in the section, which are located in the upper transverse direction in the plane direction, and of the tab-shaped electrical contact portion. a projection having upper and lower surfaces located in a direction perpendicular to the plane, and protruding from the opposing upper and lower surfaces, respectively, and protruding from the front end of the receptacle-shaped electrical contact portion located in the center of the terminal accommodating chamber; The rear surface of the protrusion toward the sleeve is an inclined surface that widens the base of the protrusion in the same direction, and protrusions that abut the rear end of the receptacle-like electrical contact portion are provided protruding from both left and right sides of the upper and lower surfaces, respectively. A sleeve for an electrical terminal, characterized in that the surfaces of the protrusions facing each other in the vertical direction toward the rear of the sleeve are sloped surfaces that widen the bases of the protrusions in the same direction.
